The job that can’t wait
We believe that people are the key 
to unlocking a clean energy future, 
and we ran a recruitment campaign 
in the UK to attract talent to ‘the 
job that can’t wait’. We were 
delighted with the response to the 
campaign, which saw a sevenfold 
increase in applications to our 
Advanced Apprenticeship scheme 
and started a national conversation 
about the importance of STEM at 
all stages of education.

Business model 
What we do

National Grid plc is one of the world’s 
largest investor-owned energy utilities, 
committed to delivering electricity and  
gas safely, reliably and efficiently to the 
customers and communities we serve.

Our core regulated businesses
National Grid owns a range of high-quality, 
long-term assets. All our assets share low 
commercial risk profiles and are typically 
supported by long-term contracts or stable 
regulatory arrangements. Our core regulated 
businesses in the UK and US generated over 
90% of our operating profits this year.

Our other energy businesses
Supporting the core regulated businesses, we 
also own a diverse and growing portfolio of 
commercial energy businesses also operating 
across the UK and US. These include our Grain 
LNG terminal and electricity interconnectors 
between the UK and continental Europe, which 
generate revenue by selling capacity to store 
or transmit energy. Our UK metering business 
generates revenue primarily through meter 
rentals. We also own a commercial property 
business which develops and sells surplus land.

Our business is organised into segments,  
based upon activity and location

Core regulated 

 UK Electricity

 US Regulated

Electricity 
Our UK electricity business comprises both 
the electricity transmission network (ET) and 
a separate Electricity System Operator (ESO). 

Electricity
We own and operate transmission facilities 
across upstate New York, Massachusetts, 
New Hampshire, Rhode Island and Vermont. 

Our electric locations by state: 
•  New York; 
•  Massachusetts; and 
•  Rhode Island. 

9,109

miles (14,659 kilometres) of overhead lines 
(2018/19: 8,881 miles; 14,293 kilometres)

Gas
We own and operate gas distribution 
networks across the northeastern US 
and are responsible for connecting millions 
of customers to the energy they use.

Our gas locations by state: 
•  New York; 
•  Massachusetts; and 
•  Rhode Island.

35,682

miles (57,425 kilometres) of gas pipelines  
(2018/19: 35,560 miles; 57,228 kilometres)

We own the high-voltage transmission 
network in England and Wales. We are 
responsible for ensuring electricity is 
transported safely and efficiently from 
where it is produced; reaching homes and 
businesses safely, reliably and efficiently. 
We also facilitate the connection of assets 
to the transmission system. 

4,481

miles (7,212 kilometres) of overhead lines 
(2018/19: 4,481 miles; 7,212 kilometres) 

1,391

miles (2,239 kilometres) of underground cable 
(2018/19: 1,437 miles; 2,312 kilometres)

Our role as ESO
The ESO now operates as a separate company 
within National Grid effective from 1 April 
2019. We are responsible for making sure 
supply and demand of electricity is balanced 
in real time across Great Britain (GB). While 
we operate as the ESO across GB, we do 
not own the transmission assets in Scotland. 

Although the ESO is legally separate from 
ET, its results are still presented to the Board 
as part of the UK segment, and therefore 
no change has been made to our 
reportable operating segments.

 UK Gas Transmission

Our UK Gas Transmission (GT) business 
comprises both the gas transmission assets 
and an integrated gas system operator. 

We also own and operate the high-pressure 
gas transmission network in Great Britain. 
We are responsible for making sure GB’s 
gas is transported safely and efficiently from 
where it is produced to where it is 
consumed. 

As the Gas System Operator we are 
responsible for ensuring that supply and 
demand are balanced in real time on a 
day-to-day basis.

  National Grid Ventures  
and other activities

National Grid Ventures (NGV) manages our diverse 
portfolio of energy businesses that are similar to 
our core regulated operations. This operating 
segment represents our main strategic growth 
area outside our regulated core business, in 
competitive markets across the US and the UK. 
The business comprises commercial operations 
in energy metering, electricity interconnectors, 
renewables development and the storage of 
liquefied natural gas (LNG) in the UK. 

In July 2019, we completed the acquisition of 
Geronimo, a leading wind and solar developer in 
North America. In December, we announced the 
start of commercial operations at the 200 MW 
Crocker Wind Farm in Clark County, South Dakota.

Our other activities that do not form part of any 
of the segments over the page or NGV, primarily 
relate to our UK property business together with 
insurance and corporate activities in the UK and 
US, and the Group’s investments in technology 
and innovation companies through National Grid 
Partners (NGP).

Business model 
How we operate

Our operating model creates a 
stable, reliable and sustainable 
business that benefits our 

What we rely on
The key internal resources that we rely  
on to do business are:
•  our physical assets that move the energy;
•  appropriate funding that allows us to invest  

in our workforce and assets; and

•  our talented workforce that ensures energy  

is moved efficiently and reliably. 

We also rely on maintaining strong relationships  
with a number of key external stakeholder groups 
to ensure we best meet their needs and maintain  
our licence to operate (see pages 44 – 47).

How we do business
We combine these input factors with our technical 
expertise to achieve our purpose and vision.

We do all of this in accordance with our culture 
and values, which guide everything that we do.

Our strategy is designed to maintain and develop 
our business model and is supported by robust 
governance and risk management processes.

The value we create
We deliver value for our stakeholders, which include our 
customers, as well as financial value for shareholders, by: 
•  operating within our regulatory frameworks thereby 

being efficient and compliant; 

•  performing well against our regulatory incentives, 
delivering customer benefits and good returns; 

•  managing our cash flow requirements and securing 

low-cost funding; and 

•  maintaining a disciplined approach to investment  

in our networks.

Internal resources

Strong relationships

Physical assets
We own electricity and gas networks that 
transmit energy over long distances from 
where it is produced. In the US, we also 
distribute it locally to where it is consumed. 
These networks are built to last for many 
decades. Such networks account for the vast 
majority of our asset base. We also own three 
subsea electricity interconnectors, with three 
further subsea cables under construction as 
well as LNG importation facilities.

Funding
We fund our business through a combination 
of shareholder equity and long and short-term 
debt. We maintain an appropriate mix of the 
two and manage financial risks prudently.

Employees
Our highly skilled, dedicated employees have 
a strong public service ethos. They manage 
and maintain the physical energy infrastructure, 
and assist and develop the many stakeholder 
relationships that are crucial to the Company’s 
success.

As we support the changes needed to build 
a net zero energy system, we are providing 
employment opportunities and supporting 
our workforce to build the skills necessary 
to support these changes. By attracting and 
retaining the people capable of supporting 
the journey to net zero in the energy sector 
we can help the places we operate reach 
their emissions targets.

23,069

employees worldwide

Customers
In the UK we do not own the energy that flows 
through our electricity cables and gas pipes. 
This energy is owned by our customers, such 
as electricity generators and gas shippers. 
These industrial customers, together with 
domestic consumers through a small portion 
of their energy bills, pay to use our networks. 
In the US, we have nearly seven million 
residential and commercial accounts.

Contractors and suppliers
We work in partnership with our supply chain, 
which has complementary experience, skillsets 
and resources. We agree mutually beneficial 
contractual arrangements and, wherever 
possible, leverage economies of scale and use 
sustainable and global sourcing opportunities. 

Communities and governments
The societal impact of our activities means 
that a range of stakeholders have a legitimate 
interest in and influence on the work we do. 
These include national and regional 
governments, local communities, our supply 
chain, and business and domestic consumers 
of the energy we transport.

Economic, health, safety and 
environmental regulators
We are subject to economic regulation by 
bodies that are entirely independent of the 
Company. These economic regulators set 
the prices we can charge for providing an 
economic, efficient and non-discriminatory 
service. Our regulated revenue therefore 
covers day-to-day running costs, financing 
capital expenditures to renew and extend our 
networks, and incentives or penalties relative 
to performance targets. It also affords our 
shareholders a fair return on their investment.

The energy we transport and the activities we 
undertake are intrinsically hazardous; therefore 
our operations have to comply with laws and 
regulations set by government agencies 
responsible for health, safety and 
environmental standards.

Our strategy places the customer at the heart 
of our decision-making and consists of three 
long-term priorities:
•  optimising our operational performance;
•  growing our core business; and
•  evolving for the future.

As the energy industry continues its transition 
to a cleaner future, we have evolved our strategy 
so that it clearly articulates our priorities, while 
positioning our business to continue to deliver 
long-term economic benefits in the regions in 
which we operate. 

The evolved strategy is founded on four 
strategic pillars which are to:
•  enable the energy transition for all;
•  deliver for our customers efficiently; 
•  grow our organisational capability; and
•  empower our people for great performance.

We have well-established governance structures 
that include comprehensive risk management, 
strong controls and financial discipline.

Revenue and profits 
The vast majority of our revenues are set in accordance with our 
regulatory agreements (see pages 28 – 37), and are calculated based 
on a number of factors including investment in network assets; 
performance against incentives; allowed returns on equity and cost 
of debt; and customer satisfaction.

Cash flows
Our ability to convert revenue to profit and cash is important. By managing 
our operations efficiently, safely and for the long term, we generate 
substantial cash flows. Coupled with long term debt financing, as well as 
additional capital generated through the take up of the shareholder scrip 
dividend option during periods of higher investment, we are able to invest 
in growing our asset base and finance returns through dividends.

Investment
We invest efficiently in our networks to deliver strong and sustainable 
growth in our regulated asset base over the long term. We continually 
assess, monitor and challenge investment decisions so we can continue 
to deliver safe, reliable and cost-effective networks.

Capital allocation
Our capital allocation is determined by the need to fund our businesses 
to deliver the investment and outputs required under our regulatory 
frameworks in the UK and US. The investments we make in our 
business seek a balance between growth and cash flow.

Chairman’s Statement

 “National Grid evolved 
its vision to reflect our 
belief that a responsible 
business needs to 
stand for something 
beyond profit.”

As we all continue to face the unprecedented 
challenge of COVID-19 around the world, 
National Grid remains committed to doing the 
right thing for our employees, our customers, 
our communities and our suppliers.

Our priority throughout this period continues to be keeping our key 
workers safe. We have well-developed procedures in place to manage 
the effect of a pandemic, and we swiftly and successfully implemented 
our business continuity plans which allowed us to maintain safe working 
environments for our workforce. That ensured they could play their part 
in this time of global crisis by keeping our networks running and the 
energy flowing to hospitals, care homes, businesses and homes. I would 
like to thank them for their dedication and resilience.

In mid-April, after our financial year end, the extraordinary resilience of 
our US employees also enabled power to be quickly restored to over 
200,000 customers across New York, Rhode Island and Massachusetts 
following extensive storm damage, despite the additional constraints 
arising from COVID-19.

Some short-term delay to our capital programmes was inevitable given 
the lockdown measures put in place by governments to control the 
spread of COVID-19. However, work on our capital programmes has 
now resumed. In the US, the suspension of debt collection and customer 
termination activities across our jurisdictions resulted in lower customer 
collections and additional provisioning for bad and doubtful debts.

We are now working diligently to prepare for the future, in which the safety 
of our employees and customers will remain of paramount importance.

The Board’s ongoing priorities are our societal responsibilities, the 
balance sheet and liquidity. In support of these and in recognition of the 
uncertainty surrounding the evolution of the pandemic, we are keeping 
a number of scenarios under regular review. Our current base case 
assumes a scenario of continued gradual easing of restrictions in all our 
operating territories, to keep the spread of the pandemic under control.

Against that backdrop, I am pleased that we are able to use our 
extensive resources to help support the communities we serve to get 
through and recover from the pandemic. Although the Company has 
implemented a number of measures to limit discretionary external 
spending, it has not implemented pay reductions, furlough or 
compulsory redundancy schemes.

National Grid plc Annual Report and Accounts 2019/20

Strategic Report | Chairman’s Statement

Nationalisation
The Board spent a lot of time in 2019 considering our response to the 
Labour Party’s proposal to nationalise nearly all of National Grid’s UK 
assets. We implemented some measures which would have strengthened 
our ability to secure a fair price for these assets, should the Labour Party 
have won the General Election. Although the Conservative Party secured 
a majority at this election, we note that the new Labour leader pledged 
his support for common ownership in a range of sectors, including 
energy, in his leadership campaign.

The path to net zero
Our focus for the future is to lead the way in the delivery of a clean 
energy transition. During the year, National Grid committed to reduce 
its own emissions to net zero by 2050, and we also saw significant 
legislative action towards a net zero ambition.

The UK and States of New York and Massachusetts each established 
legally-binding targets to achieve net zero emissions by 2050, while 
Rhode Island maintained its legally-binding target of 80% emission 
reductions by 2050. We welcome this progress as it is clear that 
decarbonisation and the pathway to reach net zero will remain one of the 
major long-term issues facing our economies.

While the pathway to decarbonisation of electricity has been identified, 
there is no obvious solution for the decarbonisation of heat. We continue 
to work with governments and others in the industry to identify solutions, 
but it is clear that the right regulatory and policy frameworks will be 
critical to enable a fair and affordable transition to a clean energy future.

Reviews
Although the power outage in Great Britain on 9 August 2019 caused 
significant disruption, the Board is pleased that the subsequent internal 
and external reviews confirmed our systems operated correctly and 
identified the failure of certain generators and railway assets as the cause. 
The external reviews highlighted a number of recommendations which 
we hope are implemented to improve the resilience of the overall GB 
infrastructure in future. The Board believes it is important that the current 
external review of the structure of the ESO results in a stable outcome 
which best enables the UK to meet its 2050 net zero commitment.

The Board was deeply concerned that the actions taken to implement 
a moratorium on new gas connections in downstate New York resulted in 
strong public criticism of the Company by Governor Cuomo, significant 
reputational damage, difficulties for customers, and a settlement with 
the New York Public Services Commission. The Board commissioned 
two external reviews which have provided valuable insights into how our 
US business got into this situation and a number of recommendations, 
which are being implemented at pace by our new President of the US 
business. As we continue working with the Public Services Commission 
to find a long-term solution, we will ensure our approach to meeting 
increasing demand for energy in New York State takes account of all 
key stakeholders.

Financial reporting
The International Financial Reporting Standard (IFRS) technical 
requirements make reporting some of the performance measures that 
we use as a regulated business challenging. We provide additional 
information, on page 32, about both our significant assets and liabilities 
that do not form part of our audited accounts, to help our investors 
gain a fair, balanced and understandable view of our business. 
Where practicable we reconcile these with our statutory measures 
in ‘Other unaudited financial information’ on pages 240 – 249.

How we generate and preserve value
Our dividend policy aims to grow the ordinary dividend per share at least 
in line with the rate of RPI inflation each year for the foreseeable future. 
As is usual practice, the Board reviews this policy regularly, taking into 
account a range of factors including expected business performance 
and regulatory developments. Following stress testing of the finances 
of the Company against a number of potential COVID-19 scenarios, the 
Board has decided to recommend a final dividend in line with this policy. 
Accordingly, the Board has recommended an increase in the final dividend 
to 32.00p per ordinary share ($2.0126  per American Depository Share). 
If approved, this will be paid on 19 August 2020 bringing the full year 
dividend to 48.57p per share ($3.0799  per American Depository Share), 
an increase of 2.60% over the 47.34p per share for the financial year 
ended 31 March 2019.

We completed the sale of our remaining stake in Cadent in June 2019 
for £1,965 million, and the proceeds were reinvested in the business to 
support the significant capital investment programme and asset growth 
across the Group over the medium term.

Regulatory issues
We continue an open dialogue with our regulators. In the UK, we submitted 
our final business plans for RIIO-2 in December 2019.

We are resuming settlement negotiations in the KEDNY/KEDLI rate 
cases in the interest of agreeing on a multi-year rate plan that mitigates 
bill impacts for our customers while allowing us to maintain safe and 
reliable service, advance our clean energy goals, and earn a reasonable 
return. If we are unable to reach a negotiated settlement, the rate cases 
will continue to a litigated outcome at which time we would then plan to 
file a new multi-year rate case proposal.

In light of the financial hardships that our customers have experienced 
from the COVID-19 pandemic, Niagara Mohawk Power Corporation 
(NMPC) delayed the implementation of certain previously approved rate 
increases. NMPC also delayed the filing of a rate case this spring and 
are exploring options including an extension of the current rate plan 
or a rate case filing later this summer.

Appointments and Board changes 
US Executive Director Dean Seavers stood down from the Board for 
personal reasons in November 2019. The Board appointed Badar Khan, 
who was already a member of the Executive Committee, as interim 
President of the US business. Following a thorough process to identify 
a permanent successor, which included both internal and external 
candidates, I’m pleased that Badar was confirmed as President of the 
US business in April 2020.

The Board was pleased to welcome two new Non-executive Directors 
during the year – Jonathan Silver, who has a strong background in 
finance and US government policy, and Liz Hewitt, who brings extensive 
business, financial and investment experience from international 
companies across a range of sectors.

You can read more details of all our Board members’ experience 
and the Committees they support in the Corporate Governance review 
on pages 63 – 107.

Culture and Responsible Business
The recent tragic death of George Floyd and the subsequent widespread 
expressions of public support for the Black Lives Matter movement have 
reinforced the right of everyone to equal opportunities, to have their voice 
heard, and to feel safe as they go about their daily life. These recent 
events highlight that companies have a vital role to play in addressing 
inequality and injustice wherever we see it, encouraging our employees 
to speak up, challenge and act where something does not feel right. 
We will not condone intolerance of any kind at National Grid.

The Board hosted several meetings throughout the year with a 
cross-section of employees to ensure the voice of the employee 
was heard by the Board, and was pleased with the effectiveness 
of these sessions.

During the year, National Grid evolved its vision to reflect our belief that 
a responsible business needs to stand for something beyond profit. 
We have a responsibility to demonstrate our commitment to society 
more broadly, and that’s why our vision is to be at the heart of a clean, 
fair and affordable energy future.

Our purpose and values are key to our Company’s DNA. In particular, 
they have enabled all our employees to respond with huge commitment, 
agility and flexibility to the challenges of COVID-19. I am immensely 
grateful to them.

Strategic Report

Chief Executive’s review

 “ National Grid has 
a leading role to play 
in ensuring a cleaner 
energy future in all 
our regions.”

by 2040. Rhode Island maintained a legally binding target to reduce 
carbon emissions by 80% by 2050 and the Governor signed an 
executive order targeting 100% renewable electricity by 2030. 

At National Grid, we have evolved our strategy and vision to reflect our 
belief that we have a responsibility to ensure that the energy future we 
help to shape is one where everyone shares the benefits and where 
we enable the communities we serve to deliver a clean transition. 
That’s why our vision is to be at the heart of a clean, fair and 
affordable energy future. You can read more about our new strategy 
on page 12. Throughout this report, we have reported our performance 
against the strategy that was effective until 31 March 2020, and which 
is set out on pages 16 – 17.

During the year, we committed to reducing our own emissions to net 
zero by 2050 and to continue to facilitate the industry-wide transition 
to a low-carbon future. 

We worked with the UK government to accelerate the transition to 
electric vehicles to cut carbon emissions and improve air quality for 
communities the length and breadth of the country. We were pleased to 
see a £500 million commitment in the 2020 Budget to support the rollout 
of new rapid-charging hubs so drivers are never more than 30 miles 
from a charging point.

We are developing the world’s first zero-carbon industrial cluster in the 
UK’s Humber region in partnership with Drax and Equinor. The Zero 
Carbon Humber consortium will use carbon capture and storage to 
create a zero-carbon region by 2040.

We are developing hydrogen trials and investing to understand the impact 
of hydrogen on our existing gas assets to address the decarbonisation 
of heat. While gas clearly has a role to play for many years to come, we 
understand the urgency of finding a solution to decarbonise heat in a 
way that is fair, affordable and not overly disruptive to consumers.

We’ve started construction work on our Viking Link interconnector, 
connecting Great Britain and Denmark, and continue construction on 
IFA2 and North Sea Link. Our interconnectors have a key role to play 
in a decarbonised energy sector, enabling the most efficient use of 
renewable energy across Europe.

Delivering for investors
During the year, we spent more than £5 billion growing and enhancing 
our US and UK energy networks, through a combination of organic 
growth, reinvesting the proceeds from the Cadent sale and innovative 
financing methods such as our green bond. We achieved this strong 
performance while also delivering a high level of asset growth of 9%. 
The proposed final dividend of 32.00p, which is still subject to shareholder 
approval, brings our full year dividend to 48.57p, an increase of 2.60% 
and in line with our policy. This is covered 1.2 times by our underlying 
earnings per share of 58.2p.

Safety
In the UK and NGV businesses, we’ve seen a strong safety performance 
this year. We continue to focus our efforts on developing a generative 
safety culture, and in the UK we’ve seen our lowest ever number of lost 
time injuries.

In the US, we’re focused on improving safety and ensuring it is front 
of mind for all our workforce after seeing a deterioration in performance 
over the last 12 months. Tragically, we also had a fatality in the US where 
one of our colleagues was struck by a vehicle which had driven into a 
clearly marked out area where he was working. 

John Pettigrew
Chief Executive
We’ve made strong progress against our 
strategic priorities despite a challenging year. 

The far-reaching and devastating global consequences of COVID-19 
cannot be underestimated and we all owe a debt of gratitude to those 
who have been on the frontline fighting this virus across the world.

At National Grid, our role throughout this crisis has been to play our part 
in keeping the lights on and the gas flowing. Keeping the networks 
running, keeping our customers connected to the power they rely on 
and expect, and protecting the communities where we live and serve 
has never been more important.

I’m immensely proud of the way all our workforce have responded to this 
pandemic, and particularly those who go out to work every day in the 
field and in our control rooms to ensure we continue to power hospitals, 
homes and society during such a challenging period.

We took immediate action to lessen any financial hardship our 
customers may have faced, suspending debt collection and customer 
termination activities across our US jurisdictions, and delaying planned 
bill increases in New York State. We have also strengthened customer 
support activities to help lower-income customers manage their energy 
bills during the crisis and beyond. 

We donated a total of £600,000 to the National Emergencies Trust, the 
Trussell Trust and University Hospitals Birmingham Charity in the UK, 
and $1 million to community-based charities across our US jurisdictions 
to provide help and support to the people that needed it most. We also 
introduced a programme of practical help, encouraging our thousands 
of UK employees to volunteer for half a day per week with charities 
working on the COVID-19 response. 

We are planning additional support activities for the communities we 
serve for the post COVID-19 environment, including employability skills 
support and helping small and local businesses in our supply chain. 
We recognise that the impact of COVID-19 will be felt over the long term, 
and we are committed to applying our Responsible Business principles 
for our workforce, our communities and the economy in our response.

While the end of the financial year was dominated by responding to the 
COVID-19 pandemic, 2019 saw uncertainties particularly in the UK where 
the external environment was dominated by Brexit and a General Election.

Leading the clean energy transition 
It’s been a year of significant progress in the clean energy transition 
with climate change rising up the agenda for the public and politicians 
alike. We’ve seen climate change protests across the world, and an 
increased commitment from governments to take action, including in 
the geographies in which we operate. The UK legislated for net zero 
emissions by 2050, and New York and Massachusetts each set an 
economy-wide limit of net zero carbon emissions by 2050, with New 
York additionally legislating the target of 100% carbon-free electricity

Strategic Report | Chief Executive’s review

Delivering for our customers
Customer performance remains a key metric and I’m pleased we’ve 
seen a steady increase in our customer satisfaction scores for GT and 
ET. However, our scores were below target in the US, our metering 
business and the ESO. We have identified areas of improvement and 
action has already started to address some of these.

IFA2, the 149-mile (240-kilometre) subsea cable between Great Britain 
and France is on track to become operational later this year, and work 
also continues on our North Sea Link to Norway which is expected to 
be operational in 2021/22. Construction is now underway on Viking 
Link, the 472-mile (760-kilometre) subsea cable between Great Britain 
and Denmark.

Optimising performance
We set out our ambition last year to increase efficiency in our UK and US 
regulated businesses, becoming more responsive to customers’ needs, 
while also delivering sustainable cost savings. This year we reduced our 
costs in both regions by significantly more than our £50 million UK target 
and the $30 million US target through a variety of measures including 
careful contract management and negotiation and improving workforce 
productivity. Removing these costs from our business will help to 
minimise future increases to customer bills.

In the UK Transmission businesses, the weighted average Return on 
Equity of 12.4% was maintained and within the 200 to 300 basis points 
outperformance that we committed to under RIIO-T1. In the US, Return 
on Equity of 9.3% represented 99% of our allowed return, benefiting 
from revenues from rate case increases in addition to control of our 
costs and was up 50 basis points on last year. Our Group Return on 
Equity was marginally lower at 11.7%, down 10 basis points from last 
year, partly due to lower income from our other businesses.

National Grid has continued to deliver world-class reliability and responded 
well to storms in the US. We were recognised with the EEI’s Emergency 
Assistance Award and the Emergency Recovery Award for our fast and 
effective response to storms in 2019. In the UK, we regret the disruption 
caused by the power outage on 9 August 2019 but welcomed the 
Ofgem and government reports into the incident which confirmed that 
the outage was not caused by National Grid infrastructure. We were 
pleased that they agreed with our view that, given an increasingly complex 
and challenging energy network, it is appropriate to carry out a review of 
the Security and Quality of Supply Standards. 

We were pleased with the stakeholder group support we received for 
the RIIO-2 business plans we submitted in December 2019. The Open 
Hearings expected in April 2020 were delayed due to COVID-19, but we 
continue to work with Ofgem and all our stakeholders to find the most 
appropriate framework to balance the needs of our customers and 
investors. You can read more about the composition of the stakeholder 
group on pages 45 – 47.

We welcomed Ofgem’s decision to apply the Strategic Wider Works model 
as part of the RIIO-T1 framework to the Hinkley Seabank Connection 
Project, which we believe is in the best interests of consumers.

In the US, we secured our Massachusetts Electric rate order with a 
five-year performance-based mechanism and an allowed Return on 
Equity of 9.6%. 

In New York, we enforced a temporary gas moratorium in May 2019, 
which led to a very challenging period for all our stakeholders. We found 
operational solutions to resolve the issue for the short term and have 
now submitted our report into long-term solutions to the State of New 
York Public Services Commission (NYPSC). We are listening to our 
stakeholders’ concerns and will continue to work with the NYPSC as 
we try to resolve the issue in the coming months.

Growing our assets 
We completed the sale of our remaining stake in Cadent for £1,965 million 
and reinvested the proceeds in our capital investment programme.

In the US, we invested £3.2 billion in the year on projects including the 
completion of the Gardenville substation upgrade in West Seneca, New 
York, which will supply an affordable and reliable source of renewable 
power for decades to come. We delivered asset growth in the US of 
12.2%, up 300 basis points on the prior year.

In the UK, we awarded the £400 million tunnelling contract for our London 
Power Tunnels 2 project in December 2019. This 20.85-mile 
(33.5-kilometre), £1 billion link will provide resilience across South London 
from Wimbledon to Crayford and is due to complete in 2028. Another 
highlight has been the completion of the tunnelling for our Feeder 9 
project under the Humber, which has been a critical investment in our 
gas infrastructure. These are just two of the projects which contributed to 
capital investment during the year of £1.3 billion and asset growth of 4%.

Our interconnector portfolio continues to grow with new subsea power 
links to France, Norway and Denmark planned over the next four years.

Evolving to a low-carbon future 
In our role at the heart of the clean energy transition, we have continued 
to take action to enable decarbonisation across our business.

We completed our acquisition of Geronimo, a leading wind and solar 
developer in North America, in July 2019. Since the acquisition, 
Geronimo has announced the commercial operation of its 200 MW 
Crocker Wind Farm in South Dakota, along with the signing of a power 
purchase agreement with Basin Electric Power Cooperative for its 
128 MW Wild Springs solar project, also in South Dakota.

The ESO is also preparing to enable a green energy future and by 2025, 
aims to have transformed the operation of Great Britain’s electricity 
system so it can operate with zero carbon.

I was pleased to note that 2019 was the cleanest year on record for the 
UK as, for the first time, the amount of zero carbon electricity used by 
the UK’s homes and businesses outstripped that from fossil fuels for a 
full 12 months.

As the UK energy industry continues to evolve, we are working closely 
with the government and regulator to review the most appropriate 
structure for the ESO following legal separation last year.

Unlocking future potential
I was pleased that our focus on diversity was recognised with Forbes 
naming us one of the Best Employers for Diversity 2020, and the US 
Human Rights Company Foundation awarding us Best Place to Work 
LGBTQ Equality. Our environmental commitments were also recognised 
with a place for the fourth consecutive year on the CDP A list, which 
names the world’s most pioneering companies leading on environmental 
transparency and performance.

National Grid continues to focus on being a responsible business and 
increasing our positive impact on society. The unprecedented global 
challenge of COVID-19 demonstrated more than ever the importance of 
being a responsible business, and we concentrated our efforts on how best 
to support our workforce and our communities through this difficult time.

In addition to the immediate volunteering programme we set up to 
support those who needed it most during the COVID-19 pandemic, 
we partner with charity organisations to encourage and enable our 
employees to volunteer with them. In early 2020, we launched a 
community investment strategy which will provide access to skills 
development for 45,000 people across the US and the UK, as we help 
to equip future generations to be part of the clean energy transition.

We invest millions every year in training to ensure our workforce have 
the skills to meet the changing needs of a net zero economy, as well 
as supporting STEM-related activities for tens of thousands of 
schoolchildren around our key infrastructure projects.

Looking ahead
I’d like to end by expressing my gratitude to all our workforce who have 
worked tirelessly to achieve the performance we have delivered this 
year, and to ensure the networks keep running as efficiently and safely 
as ever through unprecedented times.

Strategic Report

Evolving our strategy for the future

We have evolved our strategy in order to better reflect our purpose and 
in response to our business environment. 

The evolved strategy reflects a belief that we have a responsibility to 
ensure that the energy future we help to shape is one where everyone 
shares its benefits. We will continue to connect people to the energy 
they need for the lives they lead, safely, reliably and securely. 

Our purpose
Our purpose remains to Bring Energy to Life, providing the heat,  
light and power people and businesses rely on and supporting local 
communities to prosper.

like renewable natural gas, blending hydrogen in networks and carbon 
offsetting. Decarbonising transport by building electricity network 
flexibility and supporting charging infrastructure.

Empower colleagues for great performance 
Building diverse and inclusive teams that reflect the communities the 
Company serves, attracting the best talent, prioritising learning and 
developing the skills needed now and in the future to accelerate the 
energy transition.

Our values 
As a purpose-led, responsible business, how National Grid delivers for 
its customers and communities is as important as what is delivered. 
Colleagues right across the Company, in the United Kingdom and the 
United States, are committed to:

Doing the right thing, keeping customers, communities and the wider 
public safe.

Finding a better way, delivering excellent performance at best value 
and innovating new energy solutions.

Making it happen, with a strong focus on excellence, efficiency 
and results.

Strategic Report

Our business environment

As well as managing through the COVID-19 
pandemic, our societal ambition remains to 
achieve net zero, with emphasis on fairness 
and affordability, digitalisation and 
decentralisation during the transition.

2019/20 developments

Our response

Climate risk continues to rise up the 
corporate agenda, against the rapidly 
evolving societal attitudes to climate 
change and the role of energy companies 
in leading and meeting net zero 
commitments.

At least 9 countries have legislated or 
are in the process of legislating, and 
at least 112 countries are discussing 
legislating, net zero targets by 2050 
or sooner.

UK 
The UK became the first major 
economy to commit to a legally 
binding target of net zero emissions 
by 2050.

2019 was the cleanest year on record 
for the UK as, for the first time, the 
amount of zero carbon electricity used 
by the UK’s homes and businesses 
outstripped that from fossil fuels for 
a full 12 months.

US 
The states of New York and 
Massachusetts each set an 
economy-wide limit of net zero carbon 
emissions by 2050, with at least 85% 
of reductions from their states’ own 
energy and industrial emissions (and 
the remainder possible via carbon 
offsets). New York additionally 
legislated the target of 100% 
carbon-free electricity by 2040.

Rhode Island maintained a legally 
binding target to reduce carbon 
emissions by 80% below 1990 levels 
by 2050, and Governor Raimondo 
signed an executive order targeting 
100% renewable electricity by 2030.

Across the wider US, one in three 
Americans – more than 110 million 
people – live in a community which 
has committed to or achieved a 100% 
clean electricity target. 

•  In both the UK and US, we are taking important steps to address the future 
of heat, engaging across the industry and with government and regulatory 
bodies. In the US, we collaborated with industry partners to develop 
interconnection guidelines for renewable natural gas (RNG) in New York 
State that seek to facilitate growth of this clean energy resource. In the UK, 
we have conducted three feasibility studies on the potential role of 
hydrogen and how our networks could facilitate its uptake.

•  For our UK regulated business, the single biggest contributor towards 

our net zero target to reduce is Sulphur Hexaflouoride (SF6), and we will be 
leaders here. In the US, through our gas pipeline replacement programme, 
we replaced 460 miles (740 kilometres) of pipe in 2019/20, reducing 
greenhouse gas emissions from the unintended release of natural gas.
•  The ESO has agreed contracts with five parties, worth £328 million over 

a six-year period, in a world-first approach to managing the stability of the 
electricity system. This aids our ambition to be able to operate GB’s 
electricity system carbon free by 2025.

•  The world’s largest offshore wind farm, the 1.2 GW Hornsea Project One 
wind farm, is connected to our electricity transmission network and first 
generated power in 2019.

•  In January 2020, we announced the launch of our first ever green bond. 
Raising approximately €500 million, the bond’s proceeds will finance or 
refinance UK electricity transmission projects with environmental benefits.
•  We have partnered with Drax Group and Equinor to explore how large-scale 
carbon capture usage and storage and hydrogen could convert the UK’s 
Humber region into the world’s first net zero carbon industrial cluster.

•  New York Transco, a joint venture in which NGV is a partner, was selected 
to develop the New York Energy Solution transmission project, unlocking 
renewable energy upstate for customers downstate.

•  NGV completed its acquisition of Geronimo, a leading US onshore wind and 
solar developer, to establish a foundation on which to grow a large-scale 
renewables business, such as the 200 MW Crocker Wind Farm in South 
Dakota. The £209 million deal also secured a controlling share of a 379 MW 
solar and wind generation joint venture, Emerald Energy Venture LLC 
(‘Emerald’), with Washington State Investment Board.

•  Interconnectors played an important role in helping the UK use more zero 

carbon electricity than that from fossil fuels, and we are currently 
constructing three additional interconnectors: IFA2 to France, North Sea 
Link to Norway and Viking Link to Denmark.

•  We believe our gas businesses can facilitate the transition to a 

decarbonised gas system and are investing in solutions such as renewable 
natural gas and blending hydrogen in our network.

•  We have committed to meeting the Task Force on Climate-related Financial 

Disclosures (TCFD) recommendations in full (see pages 57 – 62).

Net zero
2019 was a turning point for climate 
action, from protests on the street to 
legislative action. Governments 
around the globe are considering 
and acting on ambitious carbon 
reduction targets. 

70%

National Grid’s reduction in carbon 
emissions since 1990. 

Net zero

by 2050
Our net zero commitment is to reduce 
our own greenhouse gas emissions to 
net zero by 2050.

The future of heat 
In the absence of both clear 
technology roadmaps and public 
policy frameworks that underpin the 
decarbonisation of heat by 2050, we 
currently continue to believe that our 
gas assets will have useful purposes 
beyond 2050. In common with the 
Committee on Climate Change’s Net 
Zero report in May 2019, we believe 
that the future of heat is one reliant on 
multiple technologies and fuels, with 
an enduring role for natural gas. 
However, the scale and purpose 
for which the networks will be used 
is dependent on technological 
developments and, crucially, 
policy choices of governments 
and regulators.

The future of heat is uncertain, and its 
decarbonisation is reliant on relatively 
nascent technologies, such as 
hydrogen and carbon capture usage 
and storage, as well as biogas and 
heat pumps. These new and evolving 
technologies will need to be used in 
new contexts and on a scale that has 
not yet been demonstrated. We 
do not believe that any of these 
technologies can, in the next 30 years, 
reach sufficient scale to represent an 
existential threat to our gas businesses.

2019/20 developments

Our response

UK 
Cost of energy remains a key priority, 
evidenced by 2019’s implementation 
of the energy price cap, and two of 
Ofgem’s key priorities: to ‘drive down 
prices’ and ‘decarbonise to deliver a 
net zero economy at the lowest cost 
to consumers’. 

With the government’s recent 
commitment to net zero, industry 
participants and advisors, such as 
the Committee on Climate Change, 
have stressed the importance that 
net zero is delivered in a fair way as 
a ‘just transition’ across society, with 
vulnerable consumers protected.

US 
Energy costs remain a priority for 
consumers and regulators, and 
fairness is high on the agenda in the 
discussion about decarbonisation 
pathways and their associated costs. 

State regulators continue to explore 
innovative regulatory frameworks 
that reward utilities for managing 
customer bill impacts, while delivering 
desired regulatory and policy 
outcomes. This includes adjustments 
to the cost-of-service model that 
are more forward-looking, and which 
establish new shareholder incentives 
for cost efficiency.

UK
Last year 29% of generation was 
connected at the distribution network 
level or behind-the-meter. The July 
2019 Future Energy Scenarios (FES) 
document suggested that by 2050 
this could rise to 58%. This is driven 
by new technology and business 
models enabling solutions such as 
solar panels, electric vehicles and 
battery storage to be more accessible 
to all consumers. 

US
Distributed energy resource 
investments and installations 
continue to grow across the US. 
This includes not only small-scale 
solar photovoltaics, but also electric 
vehicles, distributed storage and 
demand-side resources. Utilities 
across the country are exploring 
how to integrate these resources 
into the grid, ensuring their utilisation 
is effective, safe and reliable.

•  Our US and UK regulated businesses are pushing for greater affordability 
and innovative ways to minimise the total cost of energy to consumers.

•  In the UK, we have generated £603 million of savings for consumers 

in the first seven years of the RIIO arrangements, excluding any share 
from Cadent. 

•  Our £150 million Warm Homes Fund has helped over 42,000 households 
suffering from fuel poverty access heating systems and become more 
energy efficient. This is the largest private sector investment in energy 
efficiency ever made in the UK.

•  Our utility energy efficiency programmes continued to deliver excellent 

results for US customers, achieving annual electricity savings equal to 3.7% 
of sales in Massachusetts and 1.1% in New York. All three states that we 
serve rank in the top five in energy efficiency performance nationally 
according to the ACEEE.

•  In response to the COVID-19 crisis, we have expanded customer support, 
paused late payment collections activities, and placed a freeze on related 
service cutoffs.

•  In our Massachusetts Electric Company rate order, we gained approval 
for our proposed five-year forward-looking ratemaking mechanism that 
includes a consumer dividend and earnings sharing mechanism that 
rewards efficient company performance.

•  In upstate New York, we delivered an estimated $200 million in net societal 

benefits in our second year of performance incentives. Such benefits 
increase the affordability of energy and were achieved by reducing electric 
system peak to mitigate supply costs, increasing adoption of energy 
efficiency and facilitating uptake of heat pumps for beneficial electrification, 
among other initiatives. 

•  In Albany, New York, we worked with the public transit authority to launch 
four electric buses to test customer experience with the technology and 
enable expansion to other fleets across our territory. This is an example of 
our efforts to make electric transport options more widely accessible to all.

•  We are supporting growth in distributed energy resources (DERs) in our US 
service territories, where our US regulated business connected 314 MW of 
generation in calendar year 2019. We also made investments in the grid to 
enable future growth, including to increase distribution system capacity and 
to deploy advanced communications, monitoring and controls technologies 
essential to enhanced DER integration.

•  We continued our partnership with leading home solar panel and battery 
storage company, Sunrun, securing new contracts for grid services from 
rooftop solar and storage across the US, with nearly 40 MW capacity and 
ancillary services in calendar year 2019. 

•  Our ‘bring-your-own’ device demand response programme expanded in 
Massachusetts and Rhode Island and received the Energy Storage North 
America (ESNA) Innovation Award and the Peak Load Management Alliance 
(PLMA) Program Pacesetter Award. It enables residential customers to 
receive a financial incentive for enrolling their devices to be managed by us 
to create grid flexibility.

•  Since the start of financial year 2019/20, ET continues to process or has 

processed 207 connection applications, of which 20% have been made for 
transmission connected batteries, and a further 14% have been made up of 
a new customer type, where the customer mixes their generation make-up, 
for example solar with batteries. 

•  The ESO is working on a £10.3 million innovation project to explore how 

DERs can be used to restore power in the highly unlikely event of a total or 
partial blackout of the UK electricity transmission network.

Fairness and 
Affordability 
National Grid delivers energy safely, 
reliably and affordably to the 
communities we serve. As well as 
affordability, we will play our role 
in ensuring that no one is left behind 
in the short term during the COVID-19 
crisis, or in the longer-term transition 
to clean energy.

Decentralisation
The energy system continues its 
transition from high to low carbon. 
This change coincides with a shift 
to more decentralised generation, 
including renewables and battery 
storage. As the volume of this 
intermittent and distributed generation 
increases, a more resilient and flexible 
system will be required; one that 
makes best use of available energy 
resources to meet consumers’ needs 
in a balanced, efficient and 
economical way.

Our response

•  For our digital transformation, we are adopting a Group-wide centralised 
hub model supported by regional delivery. Strategy for the transformation 
is formed centrally with regional autonomy.

•  We expanded a personalisation platform to serve more than two million 
customers in Massachusetts and Rhode Island. Advanced data and 
analytics proactively identify eligible customers and present the next best 
offer to individuals, increasing offer enrolment and reducing bad debt. 

•  ConnectNow, our ET network connections project, will improve the 

customer experience of connecting to the network. Focusing on small  
scale connections such as solar, storage, electric vehicle charging and data 
centres, this digital platform assists customers through the application 
process, providing transparency and facilitating communication.
•  We are harnessing advances in digital technology and innovation to 

improve business performance. For example, the ESO in collaboration with 
the Alan Turing Institute has used data science and machine learning to 
deliver a 33% improvement in solar forecasting. This will help the ESO run 
the system more efficiently, and enable more solar capacity to be 
connected and utilised.

•  In 2020, the ESO launched a free Carbon Intensity application, aimed at 

empowering people to make conscious decisions about how they consume 
energy by showing them the greenest times of day to use electricity.
•  NGP invested in Dragos, a leading cybersecurity provider of industrial 
control systems and operational technology. Our cybersecurity team 
conducted a pilot of Dragos’ asset identification, threat detection and 
response software platform to help secure National Grid’s critical 
infrastructure in the UK and US. 

•  Dragos was among eight new investments and six follow-on investments 
made by NGP, whose portfolio at the close of the fiscal year comprised 
21 investments at a fair value of £134 million ($167 million).

Case study – NGV
Our response to COVID-19 in our communities
NGV has helped the University Hospitals Birmingham (UHB) Charity to 
launch a special appeal, to raise £1 million to support patients and staff 
through the COVID-19 pandemic. 

The donation has been used to purchase almost 400 tablet computers 
that will be used by patients to help them speak to their loved ones while 
they are in isolation. The tablets will be distributed across the UHB Charity’s 
five hospitals, including the Nightingale Hospital, which has recently been 
established at the National Exhibition Centre in Birmingham, UK. 

Scan here for the full story.

In 2019, the application of digital 
technologies across the energy 
industry continued at pace globally. 
Bloomberg New Energy Finance 
tracked 379 applications, projects, 
partnerships and product developments 
for industrial digitalisation. This is 78% 
more than in 2018, and they expect a 
further increase in activity in 2020, as 
positive results of digitalisation drive 
its increased use.

Utility networks in all geographies 
are identifying significant potential 
for their businesses through digital 
transformations. Advances in 
technologies to operate systems, 
manage assets and engage with 
customers will be a key facet of our 
business going forward. 

Digitalisation
Businesses and lives are being 
transformed by innovations such as 
artificial intelligence and virtual reality. 
The energy landscape has seen many 
changes as companies look to create 
new business models and reduce energy 
prices through digital technologies. 
Technology commercialisation, consumer 
demand and regulatory stimulus will 
continue to drive these trends.

Our response to COVID-19
COVID-19 is affecting countries, communities, supply chains and 
markets, including the UK and our service territory in the US. Since the 
World Health Organisation declared the outbreak as a pandemic on 
11 March 2020, National Grid has applied UK and US Federal and State 
government advice and guidance on dealing with the potential and actual 
spread and impact on our business and our customers. 

The Company has successfully activated its crisis management 
framework which includes identifying the areas that are deemed critical 
and the corresponding level of reliability and service continuity needed 
to deliver normal services during the pandemic. Our plans include 
continued safe and reliable service during large numbers of workforce 
absence due to illness. Under government guidelines in both the UK 
and the US, utility workers are identified as key/essential workers and 
have been subject to specific guidance and permissions on family 
arrangements and movements. We have moved to working from home 
arrangements, where possible, and have also identified critical areas 
including control rooms, call centres, dispatch and key sites including 
generation and LNG facilities, terminals, substations and compressor 
stations. For all these activities plans are in place to maintain critical 
safety and maintenance activities, which includes sequestering 
some employees. 

Some of our work, especially in the US, requires contact with members 
of the public. To safeguard our employees and the public we are 
following government requirements and recommendations for social 
distancing. This includes our collections, meter installations and shut-off 
arrangements while continuing to provide a safe and reliable network. 
We have also made arrangements to ensure that those customers with 
financial difficulties who cannot make payments do not have services 
cut off. 

Finally, we are also working with our supply chains so that our systems 
and networks have the necessary materials and parts. Our regular 
engagement with government agencies and our regulators, as well 
as following all advisory services regarding management of the 
spread of COVID-19, is expected to continue for the foreseeable future.

Strategic Report

Delivering against our 
strategy

Our strategy in 2019/20 focused on three 
strategic priorities for our business, 
delivering for customers safely and 
efficiently today while setting a growth 
pathway for the future.

Customer first
We have a vital role to play in 
enabling customers to benefit 
from the changes in our industry. 
The clean energy transition and 
associated technological 
advancements mean we can 
provide our customers with a 
more cost-effective service, 
while leaving no-one behind. 
We measure customer 
satisfaction as a KPI within 
each of our business segments.

16

National Grid plc Annual Report and Accounts 2019/20

Strategic Report | Delivering against our strategy

Our three strategic priorities

Examples of progress in 2019/20

1. Optimise performance
Our customers want us to be more efficient to make their 
energy more affordable, so we must find ways to improve 
how we run our business. 

We need to enhance the customer experience and our productivity through 
more efficient and customer-focused processes. Given the scale of our 
core business in the UK and US, even small improvements will have a 
huge impact on our overall performance. Finding new ways of optimising 
operations will be an important factor in our ability to compete and grow. 

•  Continued the transition begun through our UK and US programmes 
to leaner and more efficient operating models in the UK and US core 
businesses; 

•  Submitted price controls for the UK electricity, gas and system 

operator business as part of RIIO-2;

•  Received authorisation of a new five-year rate plan for our electric 

distribution companies in Massachusetts; and 

•  Continued embedding our Business Management System (BMS) 

across the Group by publishing BMS standards through the 
employee handbook, the National Grid Book, in order to increase 
standardisation across business activities.

2. Grow core business
Delivering strong operational performance provides a 
foundation from which we can invest in our core business 
and pursue other opportunities.

In the US and UK, we continue to look for business development 
opportunities that are close to our core business. 

In NGV, we will build on our successful efforts to pursue opportunities 
in interconnectors and large-scale renewables.

•  Grew our UK and US regulated businesses capex to £5.4 billion 
•  In January 2020 we celebrated the completion of the new, three-mile 

; 

(five-kilometre) Humber Tunnel that will house a key gas pipeline 
between Yorkshire and North Lincolnshire;

•  Interconnectors IFA2, Viking Link and North Sea Link are under 

construction and are on track to be delivered to plan; and 

•  Delivered the largest battery storage facility in the northeastern 
US on Nantucket as a flexible alternative to undersea cables. 

3. Evolve for the future
We need to future-proof our business against the effects 
of a changing energy landscape. Our networks are already 
managing changes to the generation mix, while the needs 
and expectations of our customers are evolving. 

Our preparations for the future are underway. For example, at NGV this 
collaboration brings together our non-network businesses to focus on 
targeted investment in the energy sector outside of our core business. 

We are also looking to develop new capabilities that are essential for 
long-term success. For example, NGP is increasing our capability in new 
and disruptive energy technologies to meet the changing needs of our 
customers and communities.

•  Following legal separation on 1 April 2019, this is the first year 
the ESO operated as a separate entity from the UK electricity 
transmission company, evolving for its customers and stakeholders; 

•  We are expanding a software platform using advanced data and 
analytics to proactively identify and present offers to customers 
in Massachusetts and Rhode Island; 

•  NGP, launched in 2018, growing with a portfolio fair value of £134m 

at 31 March 2020; and

•  NGV completed the acquisition of Geronimo, a developer of wind 

and solar generation.

Progress in 2019/20

The UK regulated businesses delivered a weighted average RoE 
of 12.4%, consistent with the return achieved in the prior year. 
US RoE increased to 9.3% (2018/19: 8.8%), with increased 
revenues from new rates driving improved US regulatory 
performance. Group RoE of 11.7% was marginally lower than 
2018/19 (11.8%), with benefits arising in the prior year from the 
Fulham property sale and US legal settlements.

Our UK customer satisfaction (CSAT) KPI comprises Ofgem’s 
electricity and gas transmission customer satisfaction scores. 
Figures represent our baseline targets set by Ofgem for reward 
or penalty under RIIO (maximum score is 10). We have seen 
a steady increase in CSAT for GT, through our efforts to 
understand the impact that our actions have with a particular 
focus on responding to their queries. In the first year post 
separation from ESO, we have also focused on building direct 
relationships with our ET customers, to understand the 
experience they need us to deliver and redesigning our service 
accordingly. Due to legal separation in April 2019, the scores 
also reflect the independent ESO result. The ESO CSAT score 
was below target for the year 2019/20 and we have identified 
query response times and tailoring communications as 
improvement areas for the next 12 months. Action has already 
begun to take place within the value streams to address these 
areas and they will form part of new insight plans for the ESO 
in 2020/21.

The US metric measures customers’ sentiment with National 
Grid by asking customers their level of trust in our advice to 
make good energy decisions. The metric, which is tied to the 
value customers feel they receive from National Grid, has 
improved over the past few years yet was below target in 2019/20. 

NPS scores reported represent the Metering business. Although 
the score has dropped since 2018/19, we have identified areas 
of improvement, for example, making sure metering queries 
raised by our customers are progressed more efficiently.

Network reliability
We aim to deliver reliability by planning our capital investments to meet challenging 
demand and supply patterns, designing and building robust networks, having 
risk-based maintenance and replacement programmes, and detailed and tested 
incident response plans. We measure network reliability separately for each of 
our business areas. The table below represents our performance across all our 
networks in terms of availability. For both our UK and US networks we continued 
to maintain excellent reliability.

Asset growth during the year was 9.0% (2018/19: 7.2%). This was 
primarily driven by the accelerated US rate base growth of 12.2% 
(2018/19: 9.2%) and higher levels of investment in other assets, 
such as in NGP. This is combined with increased UK RAV growth 
of 3.8% (2018/19: 3.6%). 

Cumulative investment in delivering new 
low-carbon energy sources (£m)
We invest in new low-carbon energy sources 
primarily through our interconnector businesses 
(North Sea Link, IFA2 and Viking Link), investments 
in companies delivering low-carbon energy 
sources (for example, our investment in Sunrun) 
and investments into large-scale renewables 
(for example, our new investment in Geronimo).

distribution network across our US footprint. Given 
the variability and unpredictability of customer-
driven projects, the Company does not presently 
have a MW target. Current targets primarily focus 
on regulatory compliance and customer need 
date attainment. 

NGV capital investment (£m) 
NGV is focused on investment in a broad range of 
energy businesses across the UK and US, including 
our interconnector business, large-scale renewable 
generation, LNG storage and regasification, and 
energy metering.

Investment in delivering new low-carbon energy sources increased 
in the year by £738 million (105%). Principally from increased 
investment in our interconnector projects under construction, with 
IFA2 nearing completion, further progress made on North Sea Link 
and the commencement of construction on Viking Link. In addition, 
the acquisition of Geronimo was made in July 2019, a leading wind 
and solar developer in North America. 

A total of 18.3 GW of low-carbon generation is currently connected 
to our network, following additional offshore wind capacity 
connecting at Hornsea 1 (+800 MW) and East Anglia 1 (+680 MW). 
The government’s offshore wind sector deal and continued cost 
reductions observed in the latest Contracts for Difference (CfD) 
allocation round, indicates further increases in capacity over the 
coming years.

There has been a 17% increase in the installed capacity compared 
to the previous year. Rhode Island installed a record amount of 
capacity (100 MW) while the installed capacity in Massachusetts 
was on par with 2018/19. Although New York experienced a 
decline in customer-ready projects to interconnect, it received a 
record amount of capacity (3,000 MW). The Company continues 
to make progress in Massachusetts and Rhode Island to enable 
greater renewable energy integration by completing area-wide 
transmission and distribution studies. While non-residential 
systems have represented less than 7% of connected applications, 
they have accounted for 78% of the installed capacity over the last 
three years.

Excluding NGP, NGV capital investment has increased in the year 
by £371 million (84%). There has been increased investment in our 
interconnector projects under construction, with IFA2 nearing 
completion, further progress made on North Sea Link and the 
commencement of construction on Viking Link. In addition, an 
acquisition of Geronimo was made in July 2019, a leading wind 
and solar developer in North America.

The majority of lost time injuries are a result of individual issues such as slips, trips and 
falls, and soft tissue injuries from inappropriate tooling, lifting and carrying. We continue 
to address these and other incidents by implementing best practice injury prevention 
techniques that mitigate potential for harm factors. Although this fiscal year saw injury 
challenges in our US business, where, tragically, we lost a colleague in a road traffic 
accident, we will continue to focus on improving our generative safety culture.

We measure employee engagement through our employee engagement survey (EES). 
The results of our 2019/20 survey, which was completed by 82% of our employees, have 
helped us identify specific areas where we are performing well and those areas we need 
to improve. At Group level, the overall results of the 2019/20 EES showed a positive trend 
from the 2018/19 survey, with 26 questions significantly improving and just seven questions 
showing a significant decline.

Our engagement score was 77%, which is four points ahead of the 2018/19 results.

During 2019/20, the representation of our female and ethnic minority groups has increased 
as we continue to build our diverse talent pipeline.

We use the London Benchmarking Group measurement framework to provide an overall 
community investment figure which includes education (but excludes investment in 
university research projects). While we have no specific target, our overall aim is to ensure 
we add value to society to enable communities to thrive. 

In the UK, the overall contribution of our activities was valued at nearly £39 million. In the 
US, our contribution was just over £7.5 million. 

This gives us a combined Group-wide contribution of nearly £47 million. This was lower 
than prior years because some events were cancelled due to COVID-19.

We measure quality (>1 hour) interactions with young people on STEM subjects. In the UK, 
in 2019/20, we have had 1,707 quality interactions with young people on STEM subjects. 
We had 51,519 interactions in the US. Overall we have seen a total of 53,226 interactions 
with young people on STEM, an increase of 11,765. 

Our Scope 1 greenhouse gas emissions for 2019/20 equate to 3.9 million tonnes of carbon 
dioxide equivalent (2018/19: 4.5 million tonnes) and our Scope 2 emissions (including 
electricity line losses) equate to 2.6 million tonnes (2018/19: 2.5 million tonnes). This is a 
total of 6.5 million tonnes of carbon dioxide equivalent for Scope 1 and 2 emissions. 
These figures include line losses and are equivalent to an intensity of around 447 tonnes 
per £1 million of revenue (2018/19: 469 tonnes). 

Our Scope 3 emissions for 2019/20 were 29.8 million tonnes (2018/19: 32.3 million tonnes).

Our global underlying energy use is 28,223 GWh where the UK and US are responsible for 
8,112 GWh and 20,111 GWh respectively. This includes gas and electricity network losses 
and fuel used for US power generation.

We measure and report in accordance with the World Resources Institute and World 
Business Council on Sustainable Development Greenhouse Gas Protocol. 100% of our 
Scope 1, 2 and 3 emissions, are independently assured against ISO 14065 Greenhouse 
Gas assurance protocol. This data complies with the UK government’s Streamlined Energy 
and Carbon Reporting (SECR) requirements and is our first disclosure to comply with SECR.

Group lost time injury frequency rate

Innovation

In our US gas businesses, our innovation continues to prioritise 
increasing public safety, protecting our workforce, reducing the cost 
of the work we perform and reducing our impact on the environment. 
For example, we are testing robotics to enhance existing pipelines and 
reduce gas emissions and have several programmes exploring the 
introduction of renewable natural gas and alternative low-carbon 
heating solutions for our customers.

National Grid Partners
NGP, our dedicated corporate innovation and investment function, has 
had a strong second year of operation delivering value to the Group. In 
2019, we established and built our central disruptive innovation capability 
while continuing to make strategic investments in our incubation and 
corporate venture capital portfolios. NGP also expanded its programming 
to include culture and entrepreneurial programming and founded a global 
utility council branded as the ‘Next Grid Alliance’ to encourage collaboration 
within our peer group on solutions for the industry. This forum of peers 
allows National Grid to tap into the wealth of innovation and investment 
learnings from across the industry and share our own best practices. 

Our investment portfolio includes direct investments in seventeen start-up 
companies and four venture funds to date with a fair value of £134m at 
31 March 2020. The venture fund investments are focused on expanding 
access to start-ups in key innovation regions including Israel and the 
United Kingdom. We also successfully exited our positions in Pixeom 
and Aporeto during 2019, providing financial returns from those investments. 

NGP’s investments provide valuable insights, collaborations and 
deployment opportunities that strengthen and future-proof our core 
business activities. For example, we have deployed cyber detection and 
response solutions from Dragos, asset management decision software 
from Copperleaf, and demand response management services from 
Autogrid. Several portfolio companies are in pilot on areas such as gas 
infrastructure risk prevention and manhole explosion prevention. 

In April 2019, we created a central innovation team, targeting disruptive 
innovations and introduced design thinking, agile delivery, and lean 
start-up methods to our organisation. While in its infancy the team 
has explored innovation opportunities in collaboration with our core 
businesses with several projects progressing into prototype stages 
during 2020. This organisation is also tasked with creating centralised 
innovation reporting to allow National Grid to track the value created 
through its sustaining innovation efforts across the Group. 

NGP has launched a series of initiatives designed to provide our employees 
with the types of experiences to further foster an entrepreneurial culture 
and skill set. These activities include an apprenticeship programme, 
entrepreneur-led speaker series, employee immersions and sprints in 
Silicon Valley, and secondments and advisory board positions within 
NGP’s portfolio. These initiatives aim to provide strong training and 
retention programmes to develop the next generation of entrepreneurial 
leaders within the Group.

NGP has delivered strategic and financial value to the core businesses 
and looks forward to delivering on our mandate to invest in valuable 
start-ups, to tackle innovation and business development projects that 
can improve our business, and to act as a catalyst for change across 
the broader Group. 

More details can be found at www.ngpartners.com including details of each 
of our portfolio investments.

Further details about our R&D and 
innovation activities can be found in 
Additional Information on pages 237 – 239.

Our innovation activities are focused 
on future-proofing the business for our 
customers as the energy landscape 
changes. Collaboration is a key part 
of our approach to innovation.

Innovation in our UK principal operations
Our commitment to net zero continues to shape our innovation strategy. 
Our innovation portfolio enables us to identify and target carbon savings 
for our own operations and we are also developing innovation projects to 
ensure we are prepared and play a pivotal role in the decarbonisation of 
energy for power and heat, transport and industry. We also search for 
new technologies and techniques to improve the way we work. 

We place a high value on collaboration to inform, generate ideas and 
solve the challenges we see ahead of us. We work in collaboration with 
technical organisations, academia and suppliers in the energy sector 
that align with our goals and objectives.

The ESO has been innovating to ensure we continue to provide secure, 
affordable and sustainable supplies of energy in a fast-changing world. 
Our innovation programme is used to learn and then accelerate market 
development. The year ahead will see even more projects generated by 
the ESO, including the world’s first Black Start from Distributed Energy 
Resources (DERs). This is a £10 million Network Innovation Competition 
(NIC) project with SP Energy Networks. It will develop and demonstrate 
coordination of DERs to provide a safe and effective Black Start service 
and lower cost to consumers.

The UK electricity transmission network is continuing with innovation 
investments. We are focused on reducing our carbon footprint from our 
construction activities and seeking ways to reduce the greenhouse gas 
impact from gas-insulated assets. We have engaged extensively with 
regional stakeholders in our Zero 2050 South Wales project to better 
understand the changes in decarbonising society and our role as a 
transmission business as our energy landscape evolves. We have made 
progress in the construction of our transmission accelerator at Deeside, 
recognising the need to test and adopt new technologies faster, and we 
continue to research technologies to enhance our cyber security and 
further digitise our grid infrastructure. 

Similarly, our UK gas transmission business has led our research to better 
understand the role of transitioning to a hydrogen future. Our Hydrogen 
Portfolio of projects aims to identify the opportunities and potential 
challenges to hydrogen injection into the National Transmission System 
(NTS). Working in collaboration with industry we aim to fill the gaps in the 
vision for a national hydrogen deployment. The portfolio includes safety 
and integrity reviews, demonstrating how existing networks can 
transition from gas to hydrogen. 

Additionally in the UK, NGV has been active in establishing consortia 
to better integrate offshore renewables, and to commercially deploy 
hydrogen and Carbon Capture and Storage technologies targeting 
industrial decarbonisation in the Humber and London regions.

Innovation in our US principal operations 
Similar to the UK, our US innovation approach is designed to enable our 
networks and customer services to adapt to a low-carbon, distributed and 
digitised future. We focus innovation and Research and Development 
(R&D) on the advancement of products, systems and work methods that 
prepare the way for more efficient and safer networks that further 
proliferate the integration of renewables. 

In Massachusetts, we continue to explore how best to integrate solar 
energy, storage and electric vehicle charging into the distribution 
network. Our Solar Phase III programme comprises an additional  
14 MW of photovoltaics (PV) and 5.8 MW of energy storage. The aim 
is to analyse the impact of future high levels of distributed renewables 
on distribution systems and in this stage the programme will also test 
the economic and technical benefits of localised balancing from energy 
storage. Several New York Reforming the Energy Vision (REV) pilots 
are also underway, testing market solutions in support of Distribution 
System Operation (DSO) developments, smart city opportunities and 
renewable heating technologies. These projects are providing the 
knowledge and experience to evolve our systems for the grid of the future.

Strategic Report

Internal control and risk management

The Board is committed to protecting and 
enhancing our reputation and assets, while 
safeguarding the interests of our shareholders.

Managing our risks
National Grid is exposed to a variety of uncertainties that could have 
a material adverse effect on the Group’s financial condition, our 
operational results, our reputation and the value of our shares.

The Board oversees the Company’s risk management and internal 
control systems. As part of this role, the Board sets and monitors the 
amount of risk the Company is prepared to seek or accept in pursuing 
our strategic objectives – our risk appetite. The Board assesses the 
Company’s principal risks and monitors the risk management process 
through risk review and challenge sessions twice a year.

Risk management process
Overall risk strategy, policy and process are set at Group level with 
implementation owned by the business. Our enterprise risk management 
process provides a framework through which we can consistently 
identify, assess, prioritise, manage, monitor and report risks. The 
process is designed to support the delivery of our vision, strategy and 
business model as described on pages 2 – 7.

Our corporate risk profile contains the principal risks that the Board 
considers to be the main uncertainties currently facing the Group as 
we endeavour to achieve our strategic objectives. These top risks are 
agreed through discussions about the Group’s risk profile with the 
Executive Committee and the Board. The risks are reported and 
debated with the Executive Committee and the Board every six months.

When determining what our principal risks should be, a broad range 
of factors are considered. We test principal risks annually to establish 
their impact on the Group’s ability to continue operating and to meet its 
liabilities over the assessment period. We test the impact of these risks 
on a reasonable worst-case basis, alone and in clusters, over a five-year 
assessment period. This work informs our viability statement (see pages 
26 – 27). The five-year period was carefully considered in light of the 
current COVID-19 pandemic. The Board considered, with appropriate 
assumptions, that this period remained appropriate for our stable 
regulated business model. The Board, Executive Committee and other 
leadership teams discuss the results of the annual principal risk testing 
at the end of the year.

Top-down, bottom-up assessment
Risk management activities take place through all levels of our 
organisation. Through a ‘top-down, bottom-up’ approach, all business 
areas identify the main risks to our business model and our business 
objectives. Each risk is assessed by considering the financial, 
operational and reputational impacts, and how likely the risk is to 
materialise. The business area identifies and implements actions to 
manage and monitor the risks. These are collated and reported at 
functional and regional levels on a regular cadence. The most 
significant risks for the UK, US and NGV businesses are highlighted 
in regional risk profiles and reported to the Executive Committee and 
the Board through a formal process twice a year. Additionally, the 
Executive Committee and the Board may also identify and assess 
other principal risks. These risks and any associated management 
actions are cascaded through the organisation as appropriate.

Emerging risks
We have an established process to identify and monitor emerging risks, 
which is designed to provide sufficient warning of concerns which may 
impact the business. The process is designed to ensure adequate steps 
are taken to prevent the occurrence or manage the impact of surprises.

The Enterprise Risk Management (ERM) process monitors management 
information from a wide variety of sources to take into account 
consideration of emerging risks. This includes:
•  Top-down analysis which is performed through the annual risk 
management process of broad thinking to consider the biggest 
impacts for the Company. 

•  Facilitation of risk discussions across our various businesses. Most 
importantly, we review various sources of management information, 
internal and external factors to identify potential emerging risks. 
•  Monitoring the external market to consider other emerging risks 

within the regions we operate in. The following diagram shows our 
approach and inputs used to analyse the emerging risks.

Changes during the year
The Company’s risk profile has been developed drawing upon the 
most significant risks across our business profiles. With the addition 
of principal risks addressing climate change and our response to the 
COVID-19 pandemic, 10 principal risks are now carried at Executive 
Committee and Board level as detailed below. All of our principal risks 
were reviewed at least twice across the year, including Key Risk Indicators 
(KRIs), developed last year to help embed the risk appetite framework 
in the business and enhance the monitoring and mitigation of risks. 

Principal risks
In 2019/20, we reviewed our assessment of the potential threats, 
opportunities and impacts from climate change. This included the 
impact of both our operations on climate change and of climate change 
on our operations, as well as the transitional risk during the journey to 
a net zero economy in developing a new climate change principal risk 
(see case study on page 23).

Since the onset of the COVID-19 pandemic, we have continually 
assessed its impact on our workforce, finances and all aspects of our 
operations, including the impact on the Electricity System Operator on 
managing the rapid decrease in energy demand across all UK networks, 
with regular reports provided to the Board. The Board has agreed that a 
new principal risk is included (see page 25). A negative outcome from 
RIIO-2 and the continuing possibility of a hard Brexit remain our most 
important emerging threats in the UK business. However, the Board 
considers, after testing with management, that these events do not need 
to be classified as principal risks as they are well covered below this level 
of risk and are regularly reviewed by the Directors. 

More recently, political escalations have been considered as a threat 
against the Company’s ability to operate in New York. Following the 
failure to obtain necessary permits to build a new pipeline, and the 
Company’s associated decision to enact a moratorium, various actions 
have been taken to address the threat of loss of licence in New York. 
During November 2019, a settlement was agreed to immediately resume 
connecting gas services in Brooklyn, Queens and Long Island for 
applications that had been put on hold. A total of $36 million in customer 
assistance, gas conservation measures and clean energy investments 
has been committed by the Company along with the appointment of an 
external monitor and the requirement to deliver a plan to address service 
to customers through winter 2020/21. The settlement agreement also 
provides a framework for identifying longer-term solutions to address 
the supply constraints in downstate New York. In considering this 
emerging threat, we have supported the Company’s other jurisdictions 
to take into consideration the possibility of New York governmental 
decisions influencing other states in the area. Both our Rhode Island 
and Massachusetts businesses have been working to lay solid 
foundations regarding clean energy strategies, investments and close 
monitoring of pipeline operations to help address these issues.

Strategic Report | Internal control and risk management

Case study on climate change moving from an emerging risk 
to a principal risk
Our risk registers typically include risks likely to manifest within the 
short to medium, rather than longer term. In the case of climate 
change, weather-related event risks previously featured, as did 
transition risks associated with the decarbonisation of heat and 
electricity and these were included as a threat in several of our 
existing principal risks (e.g. energy interruption, disruptive forces).

Over the last 12 to 18 months, facilitated workshops were held with 
each of the core businesses to ensure completeness of risk capture 
specifically relating to climate change and our net zero commitment, 
considering both physical and transitional risks.

Consideration was given to whether the individual or combined 
risks arising from increased variability in temperature, and/or greater 
wear and tear on assets under more extreme weather conditions 
such as flooding and higher temperatures, should feature more 
prominently. This was especially pertinent in the light of updates 
in climate science, observations of the changing weather such as 
increased intensity and frequency of storms on the US east coast, 
and wildfire ferocity in locations such as South America, California 
and Australia. We also understand the growing urgency to find a 
solution to decarbonise heat and the future of gas in a way that is fair, 
affordable and not overly disruptive to consumers. 

As a result, a recommendation to develop a bespoke climate change 
risk was considered by the Executive Committee and Board, and 
discussed with US, UK and NGV executives and subject matter 
experts. The addition of a bespoke climate change principal risk was 
finalised in autumn 2019. 

Our principal risks and uncertainties
Accepting that it is not possible to identify, anticipate or eliminate every risk that may arise, and that risk is an inherent part of doing business, 
our risk management process aims to provide reasonable assurance that we understand, monitor and manage the main uncertainties that we face 
in delivering our objectives. This aim includes considering inherent risks, which in turn exist because of the nature of day-to-day operations in our 
industry, and financial risks, which exist because of our financing activities. Our principal risks, and a summary of actions taken by management, 
are provided in the table below. We have provided an overview of the key inherent risks we face on pages 227 – 230, as well as our key financial 
risks, which are incorporated within note 32 to our consolidated financial statements on pages 182 – 194. Risk trends reported below take into 
account controls, any additional mitigation actions and may be influenced by internal or external developments.

People risks
It is through the high-quality work of our employees that we will achieve our vision, respond to the changing needs of our stakeholders and create a 
competitive advantage. Building and fostering an engaged and talented team that has the knowledge, training, skills and experience to deliver our 
strategic objectives is vital to our success. We must attract, integrate and retain the talent we need at all levels of the business.

Risks

Actions taken by management

Failure to build sufficient capability and leadership 
capacity (including effective succession planning) 
required to deliver our vision and strategy.

*Risk trend: Neutral (18/19 Neutral)

* Risk trends are assessed to include any external factors 
outside our control as well as the strength and 
effectiveness of our controls and additional mitigations as 
reviewed by management up to 31 March 2020.

We have embedded strategic workforce planning in our US and UK organisations. This process helps to 
effectively inform financial and business planning, as well as human resourcing needs. 

Our entry-level talent development schemes (graduate training and apprenticeships) are a potential source 
of competitive advantage in the market place. We are involved in a number of initiatives to help secure 
the future engineering talent we require, including the UK annual residential work experience week and the 
US Pipeline and Graduate Development Programmes.

We also continue to develop the rigour of our succession planning and development planning process, 
particularly at senior levels. It is now being applied deeper into the organisation as well as continued 
attention in relation to the ethnic diversity of both our management and field force population. 

There are multiple activities underway to drive this agenda, including ‘neutral’ talent and selection 
processes, development interventions and a global review of our inclusion and diversity strategy and 
resources.

During the year, in the UK, a three-year labour agreement was reached with our trade unions, introducing 
revised terms and conditions.

Financial risks
While all risks have a financial liability, financial risks are those which relate to financial controls and performance. Financial risk management is a critical process 
used to make investment decisions and aims to maximise investment returns and earnings for a given level of risk.

Our key financial risks are described in note 32 to our financial statements on pages 182 – 194.

Internal control and risk management 
continued

Strategic and regulatory risks 
Strategic risk is the risk of failing to achieve the Company’s overall strategic business plans and objectives, as well as failing to have the ‘right’ strategic plan. 
We voluntarily accept some risk so we can generate the desired returns from our strategy. 

Management of strategic risks focuses on reducing the probability that the assumed risk would materialise, while improving the Company’s ability to effectively 
respond to the risk should it occur. The risk owners, executive leaders, and their teams develop and monitor actions to control the risks. These risks link to our 
strategic priorities of ‘Grow our core business’ and ‘Evolve for the future’. The political climate and policy decisions of our regulators in 2019/20 were key 
considerations in assessing our risks.

As referred to above, the new climate change related risk is classed as a strategic and regulatory risk but is also an operational risk, in particular as regards 
weather-related events in the northeastern US (where storm planning and preparation are key to what we do), flood defence in both the UK (where flood resilience 
works are being developed) and the US (where flood contingency plans are in place) and the investigation of the impact of rising temperatures and widening 
temperature ranges on the performance and operation of our networks.

Risks

Actions taken by management

Failure to identify and/or deliver upon actions 
necessary to ensure our business model, strategy, 
asset management and operations respond to 
the physical and transitional impacts of climate 
change and demonstrate our leadership of climate 
change within the energy sector.

*Risk trend: Increasing  
(New Principal Risk)

* Risk trends are assessed to include any external factors 
outside our control as well as the strength and 
effectiveness of our controls and additional mitigations as 
reviewed by management up to 31 March 2020.

Failure to influence future energy policy and secure 
satisfactory regulatory agreements.

Risk trend: Increasing

Failure to respond to shifts in societal and political 
expectations and perceptions leads to threats to 
the Company’s licence to operate and ability to 
achieve its objectives.

Risk trend: Increasing
due to current political environment 
(18/19 Increasing Risk)

Putting in place measures to develop:
•  evolution of our environmental sustainability metrics to better reflect our strategy, measure our impact 

and track our progress; 

•  organisational design changes appropriate to meet this challenge with a single point of contact for all 

climate change actions and activities; 

•  approval of a revised environmental sustainability strategy, including our strategy for heating and gas, 

with granular actions identified to achieve net zero; and

•  working with regulators and industry parties in the UK and the US on the future of heat and the role 

of gas in the long term. 

Note that a number of the above measures also address the physical impacts of climate change on 
our operations. 

We have committed to full compliance with the Task Force on Climate-related Financial Disclosures 
(TCFD) requirements including physical and transitional scenario analysis (see pages 57 – 62).

Ongoing work to address transition risks and opportunities includes:
•  ensuring our electricity network is reliable and able to actively support and contribute to a future where 

renewables and intermittency of supply are increasing; 

•  supporting the charging infrastructure required for increased use of electric vehicles; 
•  promoting energy efficiency programmes for customers in the US; 
•  facilitating decarbonisation in the US and UK including zero carbon operation of the GB electricity 

system through ESO in the UK; and

•  continuing work on programmes to develop skills in our current and future workforce.

In both the UK and the US, we strive to maintain a good understanding of the regulatory agenda and 
emerging issues, so that robust, public interest aligned responses can be selected and developed in good 
time. Our reputation as a competent operator of important national infrastructure is critical to our ability 
to do this. We have plans and governance structures in place to address specific issues such as RIIO-2 
and US rate case filings. 

 Ongoing work to support our regulatory relationships includes:
•  our internal teams focused on messaging around gas capacity, large-scale renewables, utilities of the 

future and electric vehicles;

•  establishment of US and UK Regulatory Steering Committees; and
•  increased focus on understanding the needs and expectations of all our stakeholders through 

regulatory relationship surveys, investor surveys and review of media sentiment. 

Processes and resources are in place to review, monitor and influence perceptions of our business and 
our reputation by:
•  enhancing and consolidating our digital roadmap and social channels;
•  developing an internal forum to increase management of stakeholder and media reputational issues;
•  delivering on our commitment to be a responsible business (see pages 48 – 56);
•  implementing campaigns to recruit for the future – e.g. ‘the job that can’t wait’, (see page 1); and
•  promoting partnerships and discussions of decarbonisation across the jurisdictions where we operate.

These processes, along with twice-yearly Board strategy discussions, are reviewed regularly to ensure 
they continue to support our short- and long-term strategy. We regularly monitor and analyse market 
conditions, competitors and their potential.

Failure to adequately anticipate and minimise the 
adverse impact from disruptive forces such as 
technology and innovation on our business model.

NGP, our central innovation function, is developing our strategy with regards to new technology and 
monitoring disruptive technology and business model trends, acting as a bridge for emerging technology 
into the core regulated businesses and business development teams. 

In addition, NGP is investing in emerging start-up companies and in venture funds and the NGV function 
will further the focus on new strategies, business development and technology and innovation.

Strategic Report | Internal control and risk management

Operational risks
Operational risks relate to the losses resulting from inadequate or failed internal processes, people and systems, or due to external events. These risks normally 
fall within our low-risk appetite level as there is no strategic benefit from accepting the risk, as it will not be in line with our vision and values.

Our operational principal risks have a low likelihood of occurring. However, should an event occur, without effective prevention or mitigation controls, it would be 
likely to have a high level of impact. The risk owners, executive leaders, and their teams develop and monitor actions to control the risks. Operational risks are 
managed through policy, standards, procedure-based controls, active prevention and monitoring. The operational risks link to our strategic priority to ‘Optimise 
Performance’. Principal risk assessment includes reasonable worst-case scenario testing i.e. gas transmission pipeline failure, loss of licence to operate, cyber 
security attack – and the financial and reputational impact should a single risk or multiple risks materialise. 

Risks

Actions taken by management

Failure to prepare and respond to significant 
disruptive factors caused by the COVID-19 
pandemic because of poor development and 
execution of our response plans resulting in an 
impact on our ability to maintain our networks, 
provide service, support our people and meet our 
liquidity/financial targets, as well as reputational 
and regulatory obligations.

*Risk trend: Increasing 
(New Principal Risk)

* Risk trend for COVID-19 was assessed outside our standard 
assessment period due to the risk being added as a 
principal risk after 31 March 2020. 

Catastrophic cyber security incident caused by 
the abuse of digital systems leading to the loss of 
confidentiality, availability and integrity.

Risk trend: Increasing  
due to the dynamic nature of the cyber 
security threat 
(18/19 Increasing Risk)

Catastrophic asset failure results in a significant 
safety and/or environmental event.

Risk trend: Neutral  
(18/19 Neutral)

Failure to predict and respond to a significant 
disruption of energy that adversely affects our 
customers and/or the public.

Risk trend: Increasing 
(18/19 Neutral)

The COVID-19 pandemic impacts multiple areas of our business, therefore our response to this risk 
involves a comprehensive plan, to support the safety of our workforce and customers, that is frequently 
revised and adjusted due to the dynamic profile of this risk. This includes:
•  people: monitoring of absence and wellbeing, and monitoring of current working practices; employee 

360 degree communications planning; 

•  operations: prioritisation of critical processes, sequestering of essential staff and redeployment of 

workforce, assessment of our supply chain resilience and analysis of network availability and reliability;

•  stakeholders: frequent engagement with internal and external stakeholders, including customers, 

shareholders and regulators; 

•  safety procedures: customer and workforce engagement for essential repairs, monitoring of agreed 

regulatory deviations; and

•  finance: monitoring of cash flow levels, review and where necessary suspension of customer collection 

arrangements; access to short and long-term debt facilities.

We continue to commit significant resources and financial investment to maintain the integrity and security 
of our systems and our data by continually investing in strategies that are commensurate with the 
changing nature of the security landscape. This includes:
•  collaborative working with UK and US government agencies including the Department for Business, 

Energy and Industrial Strategy (BEIS), the Centre for Protection of National Infrastructure (CPNI) and the 
Department for Homeland Security on key cyber risks; 

•  development of an enhanced critical national infrastructure security strategy; 
•  our involvement in the US with developing the National Institute of Standards and Technology 

Cyberspace Security Framework;

•  awareness, training and self-assessments; and
•  cyber response incident procedures and contingency planning.

This year, we continued to focus on risk mitigation actions designed to reduce the risk and help meet our 
business objectives. We incorporated monitoring action status into various business processes and senior 
leadership including:
•  putting a Group-wide process safety management system in place to make sure a robust and 
consistent framework of risk management exists across our higher hazard asset portfolio, with 
safety-critical assets clearly identified on the asset register;

•  implementing asset management and data management standards with supporting guidelines to 

provide clarity around what is expected, with a strong focus on what we need in place to keep us safe, 
secure and legally compliant; and 

•  in support of this, we developed a capability framework to make sure our workforce have the 
appropriate skills and expertise to meet the performance requirements in these standards. 

We continue to apply a holistic approach encompassing preventative and mitigating actions including 
pre-emptive measures to maintain network reliability such as: 
•  flood contingency plans for substations;
•  system operator supply and demand forecasting; 
•  our UK GT Winter Preparedness Plan; 
•  US gas mains replacement programmes;
•  US storm hardening programme; and 
•  diversity of suppliers in our US gas procurement. 

Should energy flow disruptions occur:

Strategic Report

Viability statement

The Board’s consideration of the longer-term viability of the Company 
is an extension of our business planning process. The process includes 
financial forecasting, a robust risk management assessment, regular 
budget reviews as well as scenario planning incorporating industry 
trends, considering any emerging issues and economic conditions. 
Our business strategy aims to enhance our long-term prospects by 
making sure our operations and finances are sustainable. 

Utilising our established top-down/bottom-up risk management 
process, the principal risks facing the Company as described on pages 
23 – 25 are identified, monitored and challenged. Over the course of the 
year, the Board has considered the principal risks shown in the table 
below in detail. The Board considered the preventative and mitigating 
controls and risk management actions in place and discussed the 
potential financial and reputational impact of the principal risks against 
our ability to deliver the Company’s business plan. These factors were 
also carefully reassessed in light of the COVID-19 factors.

The assessment of the potential impact of our principal risks on the 
longer-term viability of the Company tests the significant solvency and 
liquidity risks involved in delivering our business objectives and priorities. 
After careful consideration of the uncertain and dynamic COVID-19 
events, including reviewing the fast-changing external factors and 
their cumulative impact in the medium and long term, and other 
considerations including: our long-term business model, high-quality, 
long-term assets and stable regulatory arrangements; the Board’s 
stewardship responsibilities; and the Company’s ability to model a range 
of severe but plausible reasonable worst-case scenarios, the Board 
concluded that it remains appropriate to consider a five-year timeframe 
over which we should assess the long-term viability of the Company.

Operational impacts 
Scenario 1 – A significant cyber-attack.

Scenario 2 – Significant supply disruption event occurring in the 
US leading to loss of licence.

Scenario 3 – A catastrophic gas pipeline failure in the US.

Scenario 4 – Emerging technology leads to significant numbers of 
people going ‘off grid’.

Scenario 5 – Significant physical damage due to climate change 
events in the US and the UK along with reputational damage 
through failure to adjust our business model to meet customer 
expectations.

Performance impacts
Scenario 6 – The breach of personal data information.

Scenario 7 – The result of a ‘Hard Brexit’ in the UK.

Scenario 8 – A poor outcome to RIIO-2 negotiations.

Cluster impacts
Scenario 9 – A significant supply disruption event in the US leading 
to loss of licence coupled with a ‘Hard Brexit’ and challenging 
RIIO-2 results in the UK.

Scenario 10 – Failure to adequately respond to the COVID-19 
pandemic including triggering a gas pipeline failure and supply 
disruption in the US leading to loss of licence coupled with 
challenging RIIO-2 results in the UK.

The following factors have been taken into account in making this decision:
•  we have reasonable clarity over a five-year period, allowing an 

appropriate assessment of our principal risks to be made;

•  in order to test the five-year period, the Board considered whether 
there are specific, foreseeable risk events relating to the principal 
risks that are likely to materialise within a five to ten-year period, and 
which might be substantial enough to affect the Company’s viability 
and therefore should be taken into account when setting the 
assessment period; and

•  each principal risk was considered for inclusion within the testing and, 
where appropriate, a reasonable worst-case scenario was identified 
and assessed for impacts on operations and/or financial performance 
over the five-year assessment time period as detailed below.

In addition to testing individual principal risks, the impact of a cluster 
of the principal risks materialising over the assessment period was 
also considered. COVID-19 and our management of the issues the 
business faces during the pandemic, was also noted as an emerging 
risk that resulted in the addition of a new principal risk. Recent external 
developments such as the Northeast Supply Enhancement (NESE) 
Pipeline and events in the downstate NY gas business regarding National 
Grid’s licence and the ability to provide continuing supply to our customers 
were also considered along with the ongoing regulatory environment in 
our operating jurisdictions. We also carefully considered the impact of 
our response to COVID-19 on our business plans and financial models. 
In the opinion of the Board, the reasonable worst-case scenarios 
represent the estimated cumulative impact with principal risk clusters.

The reputational and financial impacts for each scenario were 
considered (to the nearest £500 million). The principal risk relating to 
leadership capacity was not tested as the Board did not feel this would 
threaten the viability of the Company within the five-year assessment 
period. Further, considering the breadth of ramifications COVID-19 may 
have across different areas of the Company and its consequential power 
to exacerbate the negative consequences of other principal risks, any 
potential undesired outcome of COVID-19 was considered in 
aggregation with other principal risks in the scenarios.

The Board assessed our reputational and financial headroom and 
reviewed principal risk testing results against that headroom. The testing 
of risk groups and clusters also included an assessment of the impact 
upon the business plan, as adjusted for expected impacts of COVID-19.
No principal risk or cluster of principal risks was found to have an impact 
on the viability of the Company over the five-year assessment period. 
Preventative and mitigating controls in place to minimise the likelihood of 
occurrence and/or financial and reputational impact are contained within 
our assurance system.

In assessing the impact of the principal risks on the Company, including 
our two new principal risks of Climate Change and Response to 
COVID-19, the Board has considered the fact that we operate in stable 
markets and the robust financial position of the Group, including the 
ability to sell assets, raise capital and suspend or reduce the payment of 
dividends. It has also considered Ofgem’s legal duty to have regard to 
the need to fund the licensed activities of National Grid Gas plc, National 
Grid Electricity System Operator Limited and National Grid Electricity 
Transmission plc.

Each Director was satisfied that they had sufficient information to judge 
the viability of the Company. Based on the assessment described above 
and on pages 22 – 25 the Directors have a reasonable expectation that 
the Company will be able to continue operating and meet its liabilities 
over the period to May 2025.

Financial review 

Summary of Group financial performance  
Performance management framework 
In managing the business, we focus on various non-IFRS measures 
which provide meaningful comparisons of performance between years, 
monitor the strength of the Group’s balance sheet as well as profitability 
and reflect the Group’s regulatory economic arrangements. Such 
alternative and regulatory performance measures are supplementary to, 
and should not be regarded as a substitute for, IFRS measures, which 
we refer to as statutory results. We explain the basis of these measures 
and, where practicable, reconcile these to statutory results in ‘Other 
unaudited financial information’ on pages 240 – 249.  

Specifically, we measure the financial performance of the Group from 
different perspectives: 

•  Capital investment and asset growth: Currently we expect to invest 

c. £5 billion per year.  

•  Accounting profit: In addition to statutory IFRS measures we 

distinguish between adjusted results, which exclude exceptional 
items and remeasurements, and underlying results, which further 
take account of: (i) volumetric and other revenue timing differences 
arising from our regulatory contracts, and (ii) major storm costs, 
which are recoverable in future periods, neither of which give rise  
to economic gains or losses. In doing so, we intend to make the 
impact of such items clear to users of the financial information in  
this Annual Report. 

•  Economic profit: Measures such as Return on Equity and Value 
Added take account of the regulated value of our assets and of  
our regulatory economic arrangements to illustrate the returns 
generated on shareholder equity.  

•  Balance sheet strength: Maintaining a strong investment grade 
credit rating allows us to finance our growth ambitions at a 
competitive rate. Hence, we monitor credit metrics used by the 
major rating agencies to ensure we are generating sufficient cash 
flow to service our debts. 

This balanced range of measures of financial well-being informs our 
dividend policy, which is to grow the dividend per share at least in line 
with UK Retail Price Index inflation for the foreseeable future. 

Initial assessment of the potential impact of the COVID-19 
pandemic on the Group’s position and results
The COVID-19 pandemic has affected our reported results in the year.  
To date, we have experienced a more significant impact in our US 
businesses than in our UK businesses, mainly due to our large US 
customer base. The most significant impact on our results for 2019/20  
is the increase in the bad debt charge, which rose from £181 million last 
year to £234 million this year for the Group as a whole, and increased in 
the US from £146 million last year to £231 million this year. The increase 
in the US charge reflects the impact of moratoriums in response to 
regulatory instructions as requested by regulatory authorities in the US 
states in which we operate, which restrict our ability to collect debts due. 
However, we remain committed to continuing to supply our customers 
and termination of customer connections has been cancelled.

Additionally, in the US, lower gas volumes (reduced customer demand) 
increased timing outflows in March 2020, with warm weather also a factor  
in this increase. In our UK Transmission businesses, the disruption has 
resulted in a pause to some capex work and although some adaptations to 
the new environment have been required, there has been no significant cost 
increase in 2019/20. COVID-19 has not caused a significant disruption to 
our NGV businesses. In total, other than the US bad debt charge, there has 
been a relatively small impact on our underlying results for 2019/20 and 
incremental operating costs of around £10 million have been incurred as  
a direct consequence of the disruption caused by the pandemic.

For 2020/21, we expect some continuing impact, driven largely by our  
US operations where we are expecting (i) higher levels of bad debt,  
(ii) additional direct COVID-19 costs, and (iii) deferral of rate increases. 
However, given regulatory mechanisms and precedents, we expect to 
recover a large part of this. In the UK, we do expect to see some limited 
cost impact from COVID-19. We are also currently working with regulators 
on support mechanisms for our customers, which may lead to cash flow 
impacts in 2020/21, but we would ultimately expect to be recoverable. 
Therefore whilst COVID-19 will impact earnings and cash flow in the short 
term, we currently anticipate limited economic impact longer term. 
However, there could be a range of impacts on cash flows and earnings, 
which could be different from our current assessment.

We explain the basis of these alternative performance measures and 
regulatory performance measures and, where practicable, reconcile 
them to statutory results on pages 240 – 249.

The Group’s statutory results for the year were adversely impacted by 
exceptional charges. The impact on statutory EPS as a result of these 
charges is presented after each item. These included additional 
environmental provisions and a reduction in the discount rate applied  
to certain provisions across the Group (8.6p)and a deferred tax charge 
due to the reversal of the expected reduction in the UK corporation  
tax rate originally enacted by the Finance Act 2016 (5.6p). Last year’s 
statutory results were adversely impacted by exceptional charges 
incurred in respect of the Massachusetts Gas labour dispute (6.2p),  
our UK and US cost efficiency and restructuring programme (4.7p) and 
the impairment of development costs in respect of the termination of  
the NuGen and Horizon nuclear connection projects (3.3p). 

Statutory operating profit was also adversely impacted by commodity 
remeasurement losses of £125 million in 2019/20 (2018/19: £52 million 
gains) from mark-to-market movements on derivatives which are used  
to hedge the cost of buying wholesale gas and electricity on behalf of 
our US customers. 

Underlying operating profit was up 1% as higher rate case revenues  
in our US Regulated businesses and lower operating costs more than 
offset higher deferrable storm costs, higher bad debts costs, increased 
depreciation, the non-recurrence of favourable US legal settlements  
and sale of our Fulham property site in 2018/19. The combination of 
these factors was partly offset by higher net financing costs, driven by 
the implementation of IFRS 16 and higher average net debt. Underlying 
profit after tax increased by 1% and, combined with a higher share 
count, resulted in a 1% decrease in underlying EPS to 58.2p. 

Capital investment of £5.4 billion increased our asset growth to 9%.  
We delivered Value Added (our measure of economic profit) of £2.0 
billion in 2019/20, slightly lower than in 2018/19. Group RoE of 11.7% 
was comparable to 11.8% in 2018/19, reflecting the higher new rate 
allowances in our US businesses, while 2018/19 benefited from the 
Fulham sale and legal settlements. RCF/net debt at 9.2% remained 
consistent with the Company’s strong investment grade credit rating. 
The recommended full-year dividend per share of 48.57p is in line with 
policy and is covered 1.2 times by underlying EPS.  

28

National Grid plc Annual Report and Accounts 2019/20Strategic ReportThe adoption of IFRS 16 ‘Leases’ during the year increased our net debt by £474 million, with a corresponding increase in right-of-use assets 
recorded on the balance sheet. This standard has resulted in lower operating costs within our businesses, offset by a higher depreciation charge  
and a higher interest cost.

•  Changes in environmental provisions: a £326 million net increase in the provision for estimated costs and cost sharing allocations borne 
by the Company associated with environmental clean-up related to former manufacturing gas plant facilities, formerly owned or operated by 
the Group or its predecessor companies and additionally, £76 million for the impact of a reduction of 0.5% in the real discount rate applied to 
the environmental provisions across the Group; and 

•  Deferred tax arising on the reversal of the reduction in UK corporation tax rate: The Finance Act 2016 reduced the UK corporation 
tax rate to 17% with effect from April 2020. A £192 million deferred tax charge has been made, following the reversal of this legislation, which 
retains the UK corporation tax rate at 19%, resulting in an increase in deferred tax liabilities. 

In the prior year we classified the £283 million cost arising as a result of the Massachusetts Gas labour dispute as exceptional, along with the  
£204 million charge relating to the UK and US cost efficiency and restructuring programme and the £137 million impairment charge relating to 
nuclear connection development costs.  

We also exclude certain unrealised gains and losses on mark-to-market financial instruments from adjusted profit; see notes 5 and 6 to the financial 
statements for further information. Net remeasurement losses of £125 million on commodity contract derivatives were incurred in addition to net 
remeasurement losses of £64 million on financing-related instruments and a further £1 million of remeasurement losses related to our share of 
post-tax results of joint ventures.

Timing over/(under-recoveries)
In calculating underlying profit, we exclude regulatory revenue timing over- 
and under-recoveries and major storm costs. Under the Group’s regulatory 
frameworks, most of the revenues we are allowed to collect each year are 
governed by regulatory price controls in the UK and rate plans in the US. 
If more than this allowed level of revenue is collected, the balance must be 
returned to customers in subsequent years; likewise, if less than this level 
of revenue is collected, the balance will be recovered from customers in 
subsequent years. We also collect revenues from customers and pass 
these on to third parties (e.g. NYSERDA). These variances between allowed 
and collected revenues and timing of revenue collections for pass-through 
costs give rise to over- and under-recoveries.   

The following table summarises management’s estimates of such 
amounts for the two years ended 31 March 2020. All amounts are 
shown on a pre-tax basis and, where appropriate, opening balances  
are restated for exchange adjustments and to correspond with 
subsequent regulatory filings and calculations. All amounts are 
translated at the current year average exchange rate of $1.29:£1.

Timing over-recoveries of £146 million in UK Electricity Transmission 
were more than offset by timing under-recoveries of £54 million in UK 
Gas Transmission and timing under-recoveries of £239 million in US 
Regulated in 2019/20. In calculating the post-tax effect of these timing 
recoveries, we impute a tax rate, based on the regional marginal tax 
rates, consistent with the relative mix of UK and US balances. For the 
year ended 31 March 2020 this tax rate was 31%. 

Major storm costs
We also take account of the impact of major storm costs in the US 
where the aggregate amount is sufficiently material in any given year. 
Such costs (net of certain deductibles) are recoverable under our rate 
plans but are expensed as incurred under IFRS. Accordingly, where the 
total incurred cost (after deductibles) exceeds $100 million in any given 
year, we exclude the net costs from underlying earnings. In 2019/20, 
although we experienced a number of storms, the $98 million of 
deferrable storm costs we incurred (in aggregate) fell just below this 
threshold. During 2018/19 we experienced bad weather events across 
the year, with storms unusually occurring during April and May as well  
as in the winter months. In that year the total net costs exceeded the 
$100 million threshold and were excluded from our underlying results.

£538 million in the year. In 2018/19, there were £137 million of exceptional 
costs related to the cancellation of nuclear connections (net of termination 
income) and £100 million in relation to our cost-efficiency and restructuring 
programme. Timing over-recoveries of £146 million in 2019/20 compared 
to under-recoveries of £77 million in the prior year primarily due to the 
collection of prior year balances. 

Adjusted operating profit increased by £305 million (30%), driven by  
£223 million favourable year-on-year timing over-recoveries. Underlying 
operating profit increased by 8%. Net revenues (excluding timing) were 
relatively flat, with higher re-opener allowances for cyber and data centres, 
funding for ESO legal separation and the RPI uplift, being fully offset by 
output and allowances true-up in the annual iteration, along with lower ESO 
incentive income. Regulated controllable costs were lower, with efficiency 
savings and lower Electricity System Operator separation costs, partly offset 
by higher IT costs and inflation. Post-retirement benefit costs were little 
changed year-on-year. Other costs were lower, mainly relating to 2018/19’s 
provisions against income recognised on early termination of connections. 

The decrease in depreciation and amortisation charges reflects a benefit 
from the release of provisions related to prior years.

The statutory operating profit for all three reportable segments fell in the 
year primarily as a result of the £402 million exceptional charges referred 
to earlier. The reasons for the movements in underlying operating profit 
are described in the segmental commentaries below. Unless otherwise 
stated, the discussion of performance in the remainder of this financial 
review focuses on underlying results.

UK Gas Transmission statutory operating profit increased £80 million in 
the year. In 2018/19, £36 million of costs in relation to our efficiency and 
restructuring programme were treated as exceptional. Timing under-
recoveries of £54 million in 2019/20 compared to £38 million in the prior 
year reflecting lower than expected volumes and higher shrinkage costs. 

Adjusted operating profit increased by £45 million (15%), including  
£16 million year-on-year adverse timing under-recoveries. Underlying 
operating profit increased by 18%. Net revenue (excluding timing) was 
higher, reflecting the re-opener allowances for cyber and data centres, 
the RPI uplift and the impact of 2018/19’s Avonmouth pipeline project 
revenue allowance clawback. Regulated controllable costs were £17 
million lower, driven by efficiency savings. Post-retirement costs were 
lower, mainly related to the 2018/19 Guaranteed Minimum Pension 
(GMP) ruling. Other costs were higher principally due to the non-
recurrence of provision releases in 2018/19.

US Regulated statutory operating profit fell partly as a result of  
the £177 million year-on-year adverse swing in commodity contract 
remeasurements. Exceptional charges also increased reflecting  
£392 million environmental costs detailed above. In 2018/19, 
£283 million of exceptional costs were incurred for the Massachusetts 
Gas labour dispute in addition to £68 million of restructuring costs. 
Timing under-recoveries of £239 million in 2019/20 compared to timing 
over-recoveries of £223 million in 2018/19, driven by revenue decoupling, 
commodity recoveries and lower net energy efficiency collections 
contributed to a reduction in statutory and adjusted operating profit. 

Adjusted operating profit decreased by £327 million (19%), including 
£462 million year-on-year adverse timing under-recoveries, partly  
offset by £93 million of deferrable storm costs qualifying as major (in 
aggregate) in 2018/19. Underlying operating profit increased by 3%.  
Net revenues (excluding timing) increased by £257 million as the benefits 
of rate case increments (including KEDNY, KEDLI and Niagara Mohawk) 
and £82 million from foreign exchange movements. A stronger US dollar 
increased underlying operating profit by £23 million in the year. US 
Regulated controllable costs decreased as a result of cost efficiencies 
(principally from benefit of restructurings and contract management), 
partly offset by workload increases and inflation. Bad debt related costs 
increased by £85 million, driven by £117 million additional provision  
for receivables related to the impact of COVID-19. Depreciation and 
amortisation increased due to the growth in assets. Other costs were 
higher due to increased property taxes and higher storm costs partly 
offset by lower cost of removal. Deferrable storm costs were removed 
from underlying results last year.

National Grid Ventures’ statutory operating profits were broadly in line 
with 2018/19, with higher use of our LNG import terminal at Grain and 
lower business development costs, offset by lower revenues from our 
declining meter population and costs related to the Geronimo business. 

In ‘other’ activities, we incurred net costs of £27 million, compared to  
a net profit of £137 million in 2019/20. The performance of the Property 
business was lower than prior year reflecting the sale of the Fulham site 
to the St William joint venture in 2018/19.  Corporate and other activities 
did not include last year’s benefit of £95 million of legal settlements  
to recover costs associated with a US systems implementation. The 
National Grid Partners operating loss of £11 million was £3 million higher 
than in 2018/19.   

Financing costs and taxation 
Net finance costs 
Net finance costs (excluding remeasurements) for the year were 6% 
higher than last year at £1,049 million, with the £56 million increase 
mostly driven by the impact of IFRS 16, lower capitalised interest and 
adverse foreign exchange movements, partly offset by interest on tax 
settlements. The effective interest rate of 4.1% on net debt was 20bps 
lower than the prior year rate of 4.3%.  

Joint ventures and associates 
The Group’s share of net profits from joint ventures and associates 
increased as a result of St William’s first year of profits. Our Minnesota-
based joint venture, Emerald Energy Ventures LLC, which we acquired  
in July also contributed £1 million of post-tax earnings in 2019/20.

Tax
The underlying effective tax rate of 19.9% was 30bps higher than last 
year. The tax charge for the year benefited from the release of reserves 
following settlement of tax audits relating to earlier years and gains  
on chargeable disposals which are offset by previously unrecognised 
capital losses. In the prior year, significantly higher gains on property 
disposals that were offset by previously unrecognised capital losses 
resulted in a lower underlying effective tax rate. The Group’s tax strategy 
is detailed later in this review.

Discontinued operations 
We completed the sale of our remaining 39% interest in Quadgas 
HoldCo Limited, the holding company for the Cadent gas networks,  
in June 2019 for approximately £2 billion. As described further in  
note 10 to the financial statements, we have treated all items of  
income and expense relating to the disposal of Quadgas HoldCo  
Limited within discontinued operations.

Capital investment, asset growth and value added 
Value added is a measure that reflects the value to shareholders of our dividend and the growth in National Grid’s regulated and non-regulated 
assets (as measured in our regulated asset base, for regulated entities), net of the growth in overall debt. It is a key metric used to measure our 
performance and underpins our approach to sustainable decision-making and long-term management incentive arrangements. 

A key part of our investor proposition is growth in our regulated asset base. The regulated asset base is a regulatory construct, representing the 
invested capital on which we are authorised to earn a cash return. By investing efficiently in our networks, we add to our regulatory asset base over 
the long-term and this in turn contributes to delivering shareholder value. Our regulated asset base comprises our regulatory asset value in the UK, 
plus our rate base in the US. We also invest in related activities that are not subject to network regulation and this further contributes to asset growth.

Capital investment
Capital investment comprises capital expenditure in critical energy infrastructure, equity investments, funding contributions and loans to joint 
ventures and associates, the acquisition of Geronimo during 2019/20 and, in the case of National Grid Partners, investments in financial assets.

Investment in UK Electricity Transmission increased primarily due to Hinkley-Seabank and London Power Tunnels 2 spend. In UK Gas Transmission, 
investment reduced due to completion of the Feeder 9 gas pipeline replacement project and lower asset health spend. In the US, investment was up 
20% on a constant currency basis, reflecting increased capital expenditure in New York (gas pipe replacement and mandated gas works) and higher 
spend in Massachusetts due to 2018/19’s disruption to capex spend caused by the labour dispute. Investment in National Grid Ventures continued 
to increase with ongoing construction on three new subsea interconnectors, IFA 2 (France), North Sea Link (Norway) and Viking Link (Denmark) and 
the acquisition of Geronimo, a renewable energy business based in Minneapolis, Minnesota in July 2019 for total consideration of £209 million. In 
addition, a total amount of £61 million (including joint ventures) was invested by National Grid Partners in the year.

Asset growth and value added 
To help readers’ assessment of the financial position of the Group, the table below shows an aggregated position for the Group, as viewed from a 
regulatory perspective. The measures included in the table below are calculated in part from financial information used to derive measures sent to 
and used by our regulators in the UK and US, and accordingly inform certain of the Group’s regulatory performance measures, but are not derived 
from, and cannot be reconciled to, IFRS.  

There are certain significant assets and liabilities included in our IFRS balance sheet, which are treated differently in the analysis below, and 
to which we draw readers’ attention. These include the £1.5 billion reduction in IFRS deferred tax liabilities we recognised in relation to US tax 
reform in 2017/18, which, from a regulatory perspective, remains as a future obligation. The UK RAV is higher than the IFRS value of property, 
plant and equipment and intangibles, principally because of the annual indexation (inflationary uplift) adjustment applied to RAV, compared to  
the IFRS value of these assets (held at amortised cost). In addition, under IFRS we recognise liabilities in respect of US environmental remediation 
costs, and pension and OPEB costs. For regulatory purposes, these are not shown as obligations because we are entitled to full recovery of 
costs through our existing rate plans. In our Value Added calculation, we have recognised an asset to reflect expected future recovery of the  
£117 million COVID-19 related provision for bad and doubtful debts that we have included in 2019/20. Regulatory IOUs which reflect refunds  
due to customers in future periods are treated within this table as obligations but do not qualify for recognition as liabilities under IFRS. Adjusted 
net debt movements exclude proceeds from the Cadent disposal and, in 2019/20, exclude movements on derivatives which are designated in 
cash flow hedging arrangements and for which there is no corresponding movement in total assets and other balances.

National Grid plc Annual Report and Accounts 2019/20Strategic ReportFigures relating to prior periods have, where appropriate, been 
re-presented at constant currency, for opening balance adjustments 
following the completion of the UK regulatory reporting pack process  
in 2019, finalisation of US balances, to reflect the impact of IFRS 16  
and to remove the investment in Cadent.

During 2019/20, our combined regulated asset base and NGV and Other 
businesses’ assets grew by £3.7 billion or 9% on a constant currency 
basis compared to an increase of 7.2% in the prior year. UK RAV growth 
was 3.8% including RPI indexation of 2.6% while US rate base grew 
strongly by 12%. 

Value added, which reflects the key components of value delivery to 
shareholders (i.e. dividend and growth in the economic value of the 
Group’s assets, net of growth in net debt) was £2.0 billion in 2019/20.  
This was slightly lower than last year’s £2.1 billion, with improved US 
returns and the impact of asset growth, offset by the loss of interest and 
dividend income from Cadent and higher cash tax. Of the £2.0 billion 
value added, £0.9 billion was paid to shareholders as cash dividends  
and £1.1 billion was retained in the business. This measure excludes  
any benefit arising from the sale of our 39% interest in Quadgas Holdco 
Limited. Value added per share was 58.9p compared with 61.2p  
in 2018/19.  

Cash flow, net debt and funding 
Net debt is the aggregate of cash and cash equivalents, borrowings, 
current financial and other investments and derivatives (excluding 
commodity contract derivatives) as disclosed in note 29 to the financial 
statements. ‘Adjusted net debt’ used for the RCF/adjusted net debt 
calculation is principally adjusted for pension deficits and hybrid debt 
instruments. For a full reconciliation see page 245.  

The following table summarises the Group’s cash flow for the year,

Cash flow generated from continuing operations was £4.9 billion,  
£450 million higher than last year, principally due to exceptional items  
in 2018/19 and favourable working capital (mainly higher inflows from 
collection of prior year winter receivables), partly offset by adverse timing 
on revenues and provisions. Cash expended on investment activities 
increased for the reasons described above. Net interest paid increased 
due to the growth in net debt and also higher interest income received  
in 2018/19. The Group made net tax payments of £199 million during 
2019/20. A 46% scrip take-up in the year reduced the cash dividend to 
£892 million, £268 million lower than in 2018/19, when the scrip take-up 
was 26%. Proceeds of £1,965 million (plus £6 million of interest) from the 
Quadgas HoldCo Limited disposal, were partly offset by outflows for 
residual provisions and accruals classified within discontinued operations. 
In 2018/19, discontinued operations included dividend and interest income 
of £156 million from our investment in Quadgas. Non-cash movements 
primarily reflect changes in the sterling-dollar exchange rate, the impact  
of adopting IFRS 16 ‘Leases’, accretions on index-linked debt, finance 
lease additions and other derivative fair value movements.  

Overall, the increase in net debt was driven by continuing high levels  
of capital investment and the impact of a stronger US dollar on the 
translation of US dollar-denominated debt. As at 31 March 2020 
the Group reduced its total financial liabilities denominated in US dollars 
from $21 billion at the start of the year to $20 billion at 31 March 2020, as 
a hedge of foreign exchange movements in the value of its US businesses.  

During the year we raised over £2.9 billion of new long-term senior  
debt including 13 bond issues, and £1.1 billion of hybrid debt refinancing. 
The Board has considered the Group’s ability to finance normal 
operations at the same time as funding a significant capital programme, 
in light of the potential impacts of COVID-19. This includes stress-testing 
of the Group’s finances under a ‘reasonable worst case’ scenario and 
consideration of levers available to ensure our businesses are adequately 
financed. As a result, the Board has concluded that the Group will have 
adequate resources to do so. In April, we issued £0.9 billion of debt 
through 2 bonds, evidencing our ability to raise new finance. In addition, 
as at 17 June 2020, we have £5.8 billion of undrawn committed facilities, 
all of which have expiry dates beyond June 2021. The three major credit 
rating agencies – Moody’s, Standard & Poor’s (S&P) and Fitch – have all 
maintained their strong investment grade ratings of National Grid plc on 
stable outlook.

National Grid plc Annual Report and Accounts 2019/20Strategic Report | Financial ReviewFinancial review 
continued

Property, plant and equipment increased as a result of the continuing 
capital investment programme, foreign exchange gains and the impact 
of adopting IFRS 16 ‘Leases’. Assets held for sale comprised our 39% 
interest in Quadgas, which was sold in June 2019. Pension liabilities 
increased in the US, as a result of lower asset valuations and foreign 
exchange movements, partly offset by a lower discount rate. Provisions 
increased principally as a result of additional environmental provisions 
recognised in the year and foreign exchange movements. Other 
movements are largely explained by net working capital inflows and 
changes in the sterling-dollar exchange rate.

Regulatory gearing, measured as net debt as a proportion of total 
regulatory asset value and other business invested capital, was 63% as 
at 31 March 2020. This was down from 66% at the previous year-end 
and remains appropriate for the current Group credit rating of A-/A3 
(S&P/Moody’s). 

Retained cash flow as a proportion of adjusted net debt was 9.2%, 
which is above the long-term average 9% level currently indicated by 
Moody’s as consistent with maintaining our current Group rating.

Off-balance sheet items 
There were no significant off-balance sheet items other than 
the commitments and contingencies detailed in note 30 of the 
financial statements. 

Economic returns 
In addition to value added, one of the principal ways in which we 
measure our performance in generating value for shareholders is 
to divide regulated financial performance by regulatory equity, to 
produce Return on Equity (RoE). 

As explained on page 245, regulated financial performance adjusts 
reported operating profit to reflect the impact of the Group’s various 
regulatory economic arrangements in the UK and US. In order to 
show underlying performance, we calculate RoE measures excluding 
exceptional items of income or expenditure. 

Group RoE is used to measure our performance in generating 
value for our shareholders by dividing regulated and non-regulated 
financial performance, after interest and tax, by our measure of equity 
investment in all our businesses, including the regulated businesses, 
NGV and Other activities and joint ventures. 

Regulated RoEs are measures of how the businesses are performing 
compared to the assumptions and allowances set by our regulators.  
US and UK regulated returns are calculated using the capital structure 
assumed within their respective regulatory arrangements and, in the 
case of the UK, assuming 3% RPI inflation. As these assumptions 
differ between the UK and the US, RoE measures are not directly 
comparable between the two geographies. In our performance 
measures, we compare achieved RoEs to the level assumed when 
setting base rate and revenue allowances in each jurisdiction.

The overall weighted average RoE for the two UK transmission 
businesses was 12.4%, representing 230 basis points outperformance 
of the base allowed return. Electricity Transmission performance 
reduced in the year with improved totex incentive performance offset by 
lower SO incentives including a reversal of profits recognised in 2018/19. 
Gas Transmission return increased due to improved totex performance 
in 2019/20.

RoE for the US Regulated business of 9.3% was 50bps higher in 
2019/20, with improved performances in KEDNY, across Massachusetts 
and in Rhode Island all contributing to this increase. The achieved  
RoE represents 99% of the weighted average allowed return across  
all jurisdictions. US returns exclude the impact of the Massachusetts 
Gas labour dispute in 2018/19. They are also not impacted by the 
COVID-19 related bad debt provision recognised in 2019/20 and include 
an adjustment reflecting our expectation for future recovery of these  
bad debt costs. 

Overall Group RoE, which incorporates Property, Corporate and Other, 
and financing performance was 11.7%, slightly lower than 2018/19. 

Tax transparency
As a responsible tax payer, we have voluntarily increased our tax 
disclosures, which continue to be an area of significant interest to  
many of our stakeholders.

Tax strategy
National Grid is a responsible tax payer. Our approach to tax is consistent 
with the Group’s broader commitments to doing business responsibly and 
upholding the highest ethical standards. This includes managing our tax 
affairs, as we recognise that our tax contribution supports public services 
and the wider economy. We endeavour to manage our tax affairs so that 
we pay and collect the right amount of tax, at the right time, in accordance 
with the tax laws in all the territories in which we operate. We will claim 
valid tax reliefs and incentives where these are applicable to our business 
operations, but only where they are widely accepted through the relevant 
tax legislation such as those established by government to promote 
investment, employment and economic growth. We do not have 
operations in tax havens or low tax jurisdictions without commercial 
purpose.

We have a strong governance framework and our internal control and 
risk management framework helps us manage risks, including tax risk, 
appropriately. We take a conservative approach to tax risk. However, 
there is no prescriptive level or pre-defined limit to the amount of 
acceptable tax risk. 

We act with openness and honesty when engaging with relevant tax 
authorities and seek to work with tax authorities on a real-time basis. 
We engage proactively in developments of external tax policy and 
engage with relevant bodies where appropriate. Ultimate responsibility 
and oversight of our tax strategy and governance rests with the Finance 
Committee, with executive management delegated to our CFO. For 
more detailed information, please refer to our published global tax 
strategy on our website.

Our Hong Kong entity is UK tax resident and our entities in Australia  
and Canada are dormant. Therefore, those jurisdictions have not been 
included in the table above.

Our Isle of Man company is a captive insurance company which  
is treated as a controlled foreign company for UK tax purposes and  
as such UK corporation tax is paid on its profits by National Grid. In  
the Netherlands, we have a finance company which raised external 
finance for the Group and an old holding company which held trading 
investments which were sold many years ago, which is in the process  
of being liquidated. The finance company is taxed on its profits in  
the Netherlands at the corporate tax rate of 25%, whilst the holding 
company’s profits are offset by tax losses on which deferred tax has  
not previously been recognised.

Transfer pricing is not a significant issue for the Group since there are 
limited transactions between Group companies, but any transactions 
between related parties are made on an arm’s-length basis and aligned 
to OECD principles.

Group’s total tax charge to tax paid
The total tax charge for the year disclosed in the financial statements  
in accordance with accounting standards and the equivalent total 
corporate income tax paid during the year will differ.

The principal differences between these two measures are as follows:

1.   Tax refunds in respect of prior years are primarily driven by a refund received in respect of tax 
losses carried back to earlier years following agreement of historical US Federal tax audits.

2.  Profit/(loss) before income tax from continuing operations after exceptionals.

Effective cash tax rate
The effective cash tax rate for the Group is 11.3%. The difference 
between this and the accounting effective rate of 27.4% (see note 7  
on page 143) is due to the following factors.

National Grid is a capital-intensive business, across both the UK and 
the US, and as such invests significant sums each year in its networks. 
In 2019/20 the total capital expenditure was £5,079 million. To promote 
investment, tax legislation allows a deduction for qualifying capital 
expenditure at a faster rate than the associated depreciation in the 
statutory accounts. The impact of this is to defer cash tax payments 
into future years.

Given the substantial amounts of expenditure qualifying for deduction 
incurred by National Grid this has left us in a net tax loss position in the 
US in the year ended 31 March 2020. Consequently, in the current 
period we made no significant federal tax payments.

In the current year we made significant cash tax payments in the UK 
(£306 million). This was offset by the receipt of cash for tax losses 
carried back to earlier years in the US as a result of settlement of prior 
year audits. These receipts in the US also contributed to a lower overall 
effective rate of cash tax for the Group.

The Group continues to fund deficit payments into its defined benefit 
pension schemes and has made significant payments into the Gas and 
Electricity schemes during the course of the year. These payments have 
further reduced the overall cash tax paid in the UK.

Group’s total tax contribution 
In the current year we have expanded this disclosure to cover our global 
total tax contribution. The total amount of taxes we pay and collect 
globally year-on-year is significantly more than just the tax which we pay 
on our global profits. 

Group’s total tax contribution 2019/20 (taxes paid/collected)

For 2019/20 our total tax contribution globally was £2,794 million 
(2018/19: £2,620 million), taxes borne were £1,635 million (2018/19: 
£1,422 million) and taxes collected were £1,159 million (2018/19:  
£1,198 million). Whilst total tax collected in 2019/20 has remained 
consistent with the prior year, the total taxes borne by the Group has 
increased from the prior year primarily as a result of higher property  
and profit taxes being paid.

Two thirds of the tax borne by the Group is in relation to property taxes 
of which c. £850 million are paid in the US across over 1,100 cities and 
towns in Massachusetts, New Hampshire, New York, Rhode Island and 
Vermont. These taxes are the municipalities principal source of revenue 
to fund school districts, police and fire departments, road construction 
and other local services.

In the UK we participate in the 100 Group’s Total Tax Contribution 
Survey. The survey ranks the UK’s biggest listed companies in terms  
of their contribution to the total UK government’s tax receipts. The  
most recent results of the survey for 2018/19 ranks National Grid as  
21st highest contributor of UK taxes (2017/18: 25th), 18th in respect of  
taxes borne (2017/18: 23rd) and 5th in respect of capital expenditure 
(£1,200 million) on fixed assets (2017/18: 4th). Our ranking in the survey  
is proportionate to the size of our business and capitalisation relative  
to the other contributors to the survey.

However, National Grid’s contribution to the UK and US economies is 
broader than just the taxes it pays over to and collects on behalf of the 
tax authorities.

Both in the UK and the US we employ thousands of individuals directly. 
We also support jobs in the construction industry through our capital 
expenditure, which in 2019/20 was £5,079 million, as well as supporting 
a significant number of jobs in our supply chain. 

Furthermore, as a utility we provide a core essential service which allows 
the infrastructure of the country/states we operate in to run smoothly. 
This enables individuals and businesses to flourish and contribute to  
the economy and society.

Development of future tax policy 
We believe that the continued development of a coherent and 
transparent tax policy across the Group is critical to help drive growth  
in the economy. In the UK we continue to contribute to research into  
the structure of business tax and its economic impact by contributing  
to the funding of the Oxford University Centre for Business Tax at the 
Saïd Business School. 

We are a member of a number of industry groups which participate in 
the development of future tax policy, such as the Electricity Tax Forum 
and CBI Employment Taxes Working Group, together with the 100 
Group in the UK, which represents the views of Finance Directors  
of FTSE 100 companies and several other large UK companies. We 
undertake similar activities in the US, where the Company is an active 
member in the Edison Electric Institute, the American Gas Association 
and the Global Business Alliance. This helps to ensure that we are 
engaged at the earliest opportunity on tax issues which affect our 
business.

We continue to engage on consultations where the subject matter of 
which directly impacts taxes borne or collected by our business, with  
the aim of openly contributing to the debate and development of tax 
legislation.

National Grid plc Annual Report and Accounts 2019/20Strategic ReportBrexit
As described elsewhere in the Strategic Report, our Brexit working 
group considered the issues and consequences of the UK’s decision  
to leave the EU. In the last month of 2018/19, and in anticipation of the 
original 29 March 2019 deadline for the UK to exit the EU, we executed 
our plan to bring forward the procurement of key items for capital 
delivery and operations in case of delays at ports. In the context of the 
Group financial statements, however, these actions did not have a 
material effect.

New accounting standards
As of 1 April 2019, we adopted IFRS 16 ‘Leases’. This did not have a 
material impact on the Group’s results or financial position, although  
as described in note 37 to the financial statements, on transition our 
property, plant and equipment and net debt each increased by  
£0.5 billion to take account of the additional lease obligations. We  
note that the rating agencies already made adjustments to impute  
this and accordingly, adoption of the new standard does not impact  
our credit ratings. 

Post balance sheet events
In the period between 31 March 2020 and 17 June 2020, there  
have continued to be substantial environmental, economic and  
social changes in both the UK and US. As described further in the 
Strategic Report, these have had, and will continue to have, significant 
ramifications for the Group. Other than as disclosed in respect of those 
areas where forward-looking forecasts are relevant (notably goodwill 
impairment reviews (note 11 to the financial statements), expected credit 
losses on financial instruments including trade receivables (notes 19  
and 32) and the presumption of the going concern basis generally  
(note 1)), none of these developments have impacted or caused 
adjustment to the financial statements.

Pensions 
In 2019/20, the defined benefits pensions and other post-retirement 
benefits operating costs decreased by £97 million to £197 million, 
principally as a result of our UK restructuring programme and the  
GMP equalisation ruling. Employer contributions during the year  
were £327 million (2018/19: £418 million), including £86 million  
(2018/19: £84 million) of deficit contributions. 

As at 31 March 2020, the total UK and US assets and liabilities and the 
overall net IAS 19 (revised) accounting deficit is shown below. Further 
information can be found in note 25 to the financial statements.

As at 31 March 2020, pension assets of £1,589 million in the UK pension 
schemes and £260 million in the US Niagara Mohawk Plan were 
recognised on the basis that these plans were in a surplus position. 

Dividend
The Board has recommended an increase in the final dividend to 32.00p 
per ordinary share ($2.0126 per American Depository Share) which will 
be paid on 19 August 2020 to shareholders on the register of members 
as at 3 July 2020. If approved, this will bring the full year dividend to 
48.57p per ordinary share, an increase of 2.6% over the 47.34p per 
ordinary share in respect of the financial year ended 31 March 2019.  
This is in line with the increase in average UK RPI inflation for the year 
ended 31 March 2020 as set out in the announcement of 28 March 
2013, in which we stated that our dividend policy aims to grow the 
ordinary dividend per share at least in line with the rate of RPI inflation 
each year for the foreseeable future.

At 31 March 2020, National Grid plc had in excess of £5 billion of 
distributable reserves, which is sufficient to cover more than two years  
of forecast Group dividends. If approved, the final dividend will absorb 
approximately £1,123 million of shareholders’ funds. This year’s dividend 
is covered approximately 1.2x by underlying earnings. 

The Directors consider the Group’s capital structure and dividend policy 
at least twice a year when proposing an interim and final dividend and 
aim to maintain distributable reserves that provide adequate cover for 
dividend payments.

Highlights
Our UK business performed well in 2019/20 as we maintained our 
focus on safe, customer-led, reliable, innovative and efficient operations. 
On 1 April 2019, we completed the legal separation of the ESO within 
a newly formed subsidiary company which holds the ESO licence. 
To ensure appropriate ring-fencing between itself and the rest of the 
National Grid Group, the company is governed by its own Board of 
Directors including three independent directors. Following separation, 
we moved the Gas System Operator (GSO) function to become part 
of the Gas Transmission business to further simplify our structure.

Optimise performance
Our safety ambition is to have a culture where we always do the right 
thing regarding safety. Our strategy is to be proactive in our safety 
management by engaging our leaders and employees and implementing 
a consistent and simple risk-based approach. This strategy will enable 
us to develop the highest level of safety culture maturity. To support this 
ambition, we are focusing more on leading indicators that measure our 
positive efforts on safety management to help prevent incidents, while 
continuing to track more traditional lagging indicators.

As at 31 March 2020, our LTIFR was 0.06. This is better than our UK 
target of <0.08, and is our best ever LTIFR performance. Our Electricity 
Capital Delivery business has worked more than a year without having 
any LTIs in approaching five million person hours of complex 
construction activity. This outstanding result was driven by a relentless 
focus on the work we do and commitment to keeping one another safe. 

38

We delivered a good year of returns, with a Return on Equity of 12.4%. 
Statutory operating profit and underlying operating profit were higher 
at £1,663 million and £1,576 million respectively.

We have committed to reduce our direct emissions to net zero by 2050 
and to increase our influence to support the overall industry-wide 
transition to a low-carbon future. We have developed solutions to enable 
the rollout of a strategic backbone for electric vehicles throughout the 
UK and are working in partnership with industry to develop Carbon 
Capture and Storage (CCS) solutions. We continue to engage with 
stakeholders to shape and define the delivery of the £500 million funding 
commitments to help grow the UK’s rapid charging network made in the 
Chancellor’s March 2020 Budget. In addition, the Chancellor announced 
at least £800 million for a CCS Infrastructure Fund which will support 
CCS in at least two sites.

Following the floods of 2007, we instigated an investment programme 
to protect assets against future flooding. The programme ensures overall 
resilience of the network to threats, focusing on protection of specific 
sites against the threat of flooding and reducing the likelihood of 
consumers being affected by a flooding incident on the ET system. 
Following detailed modelling and consultation with the Environment 
Agency, permanent flood defences were installed at Thorpe Marsh 
400 kV substation in 2014 and a demountable barrier was procured to 
protect the 275 kV substation which is located on higher ground. Neither 
of the substations were jeopardised during the flooding event. The ET 
network remained resilient during Storm Ciara in February 2020.

Customer first
As noted in the Chief Executive’s review, at the end of 2019/20, we found 
new ways to put the customer first in the face of the COVID-19 pandemic.

We work with our customers to meet their needs and deliver successful 
outcomes for all parties. We were pleased to see continued improvement 
in our CSAT scores in our ET and GT businesses, achieving scores of 
8.2 (2018/19: 7.9) and 8.0 (2018/19: 7.8) respectively. For the ESO, our 
CSAT score in 2019/20 was 7.6.

In October 2019, we welcomed Ofgem’s ‘minded-to’ position on 
Hinkley-Seabank connection to use the existing Strategic Wider Works 
(SWW) mechanism for this vital project. In May 2020, we reached 
agreement on the final cost and the regulatory funding model. The 
allowance for the project is £656 million and will be funded through 
the existing SWW mechanism rather than the Competition Proxy Model 
(CPM). The project remains on target to be ready for connection in 2025.

Grow core business
In December we awarded the £400 million tunnelling contract 
associated with our London Power Tunnels 2 project, a 20.8 mile 
(33.5 kilometre), £1 billion link from Wimbledon to Crayford which will 
provide significant resilience across South London when completed in 
2028. We have embarked on a partnership with a social enterprise, My 
Kinda Future, to inspire the next generation of engineers in South London 
and to help us with local recruitment and upskilling required around our 
key sites. The team will work on designs and set up across key sites this 
year, launching four different tunnel-boring machines in 2021. Four other 
major contracts associated with the cable and substation works will be 
let this year. These partners will form an enterprise, focused on innovation 
and collaboration to successfully deliver the project outcome, rewiring 
London and connecting with the capital. 

We took over the Western Link HVDC cable with our Joint Venture 
partner Scottish Power Transmission on 23 November 2019. The link is 
a submarine HVDC link between Scotland and England and Wales which 
delivers up to 2,250 MW. We are working with Ofgem after they opened an 
investigation into the delivery and operation of the cable in January 2020.

A particular highlight has been the completion of the tunnelling for Feeder 9 
under the Humber estuary, a critical reinforcement of the gas network.

Evolve for the future
We published and submitted our business plans to Ofgem in December 
2019 for our ET, GT and ESO businesses for the 2021–2026 RIIO-2 price 
control period. These plans have been developed following our largest 
ever engagement exercise to date, with customers, industry stakeholders, 
businesses and households across the country. 

National Grid plc Annual Report and Accounts 2019/20

Strategic Report | Principal operations – UK

Our plans include investment to maintain network reliability and provide 
flexibility and optionality for the UK to achieve net zero greenhouse gas 
emissions by 2050, while being protected against new threats:
•  Our ET plan has a baseline total expenditure spend of £7.1 billion over 
the five-year period. Our ET business assumes connection of 15.3 GW 
of customer capacity, providing the UK with clean power and flexible 
storage, as well as increased investment to maintain reliability and 
resilience. The baseline spend for ET, under our proposed financial 
plan, would see consumer bills reduce slightly in real terms. 

•  Our GT plan has a baseline total expenditure spend of £2.8 billion 

over the five-year period. Our GT business, which comprises GB gas 
system operator and gas transmission, includes an increase in asset 
health and cyber resilience investment, as well as a programme of 
work to test and prove hydrogen conversion options. The baseline 
spend for GT, under our proposed financial plan, would see 
consumer bills reduce slightly in real terms. 

These plans will deliver a safer, cleaner, greener and more affordable 
energy system. We have challenged ourselves to ensure our business 
plans deliver at the lowest cost and create optionality as we develop 
the pathway to net zero. We continue to constructively work with our 
regulator, Ofgem, ahead of draft determinations in the summer and final 
determinations in November 2020.

The wellbeing of our workforce is important to us. 38% of our UK 
employees have undertaken mental-health-related training courses 
during the year, an increase of 30% compared to last year.

The UK cost efficiency programme that we announced in 2018 
continues to deliver a more efficient and agile business ahead of RIIO-2. 
Through this initiative we have simplified ways of working with a leaner 
organisation and more efficient IT and back office activities. In 2019/20, 
the programme enabled us to deliver efficiency savings of £54 million 
in ET, and £19 million in GT.

We have made good progress on the £116 million Dorset Visual Impact 
Provision (VIP) project, with site establishment and preliminary civil works 
well underway. We are on track to underground 5.5 miles (8.8 kilometres) 
of overhead line and remove 22 pylons in the Dorset Area of Outstanding 
Natural Beauty (AONB) by 2022. Funding and planning applications have 
been submitted for the Peak District East VIP project. This £43 million 
project will remove six pylons and 1.2 miles (2 kilometres) of overhead 
line in the Peak District National Park. The planning application for 
Snowdonia VIP project has been submitted. This project will replace a

section of overhead line which goes through Snowdonia National Park 
with cables in a 2.1 mile (3.4 kilometre) tunnel. Engineering and 
consenting activities have also commenced on the first of our RIIO-2 
portfolio of VIP projects: the undergrounding of 2.7 miles (4.4 kilometres) 
of overhead line through the North Wessex Downs AONB.

Our GSO became part of the GT business with effect from 1 January 
2020, providing even greater transparency and clarity around the 
management of Great Britain’s gas and electricity networks. A unified 
GSO and GT structure is a better way to be organised, offering greater 
alignment, simplified governance, clearer accountability, and better 
coordination between system operator and gas asset management. 
It makes the legal separation of the ESO even clearer.

In our GT business we are reviewing the potential to decarbonise the gas 
network through a transition to carbon-free hydrogen. Working with the 
UK gas networks on the Gas Goes Green programme, we are identifying 
the steps required to repurpose our assets to carry hydrogen either as a 
blend or up to 100%.

System Operator
As the ESO, we continue to help facilitate the move to a lower-carbon 
economy while simultaneously delivering safe, reliable and affordable 
energy to the end consumer. We operate an electricity system that is 
transitioning towards net zero and have seen several new energy 
records set, as greater levels of renewables continue to connect to 
the network and coal power stations close. During the spring of 2019 
there were 18 consecutive days where coal-fired generation was not 
part of the generation mix; solar output peaked in May 2019 at 
around 9.5 GW and the maximum wind output of 16.86 GW was 
recorded in December 2019. In combination, these changes to the 
generation mix have led to 2019 being the first year on record in 
which low-carbon sources generated more electricity than fossil fuel 
sources. In 2020, we have continued to see further records set. 
Further details about the ESO power generation mix can be found at: 
www.nationalgrideso.com/great-britains-electricity-explained

Our ESO RIIO-2 plan proposes new activities that will generate net 
benefits of around £2 billion for consumers over the five-year RIIO-2 
period and spend over its two-year price control (2021–2023) of £514 
million. The ambitious ESO plan focuses on how the ESO must 
evolve to meet the challenges of the changing energy landscape. 
Supported by a new, bespoke regulatory model designed to drive the 
right behaviours and outcomes, the ESO will facilitate the transition to 
a zero-carbon power system. Under RIIO-2, the ESO will lower 
average annual consumer bills by around £3.

Following the cessation of the UK’s Capacity Market scheme in 
November 2018 due to the ruling of the European Court of Justice, 
we worked closely with BEIS and Ofgem to initiate contingency plans 
making sure that security of supply could be maintained during the 
2019/20 winter period. On 24 October 2019, the EU Commission 

ruled on the validity of the Capacity Market state aid challenge, 
confirming their original decision in 2015 to grant state aid approval. 
Following the announcement, we have resumed our role as the 
Electricity Market Delivery Body and ran auctions in early 2020. 

On 15 May 2018, Ofgem opened an investigation into the ESO (when 
it still formed part of National Grid Electricity Transmission plc) 
pertaining to an alleged breach of its licence condition to operate the 
system in an economic and efficient manner, including the production 
and publication of forecasts of demand on the electricity transmission 
network. The investigation is ongoing. 

On 9 August 2019, following the near simultaneous tripping of two 
large power generators, we experienced power outages in various 
parts of England and Wales. The frequency on our network dropped 
resulting in low frequency demand disconnections, preventing further 
issues. Service was restored within 45 minutes to all customers. In 
September 2019, we published the technical report into the event. In 
January 2020 Ofgem published its findings which supported many of 
the recommendations we included in our report. We operate one of 
the safest and most resilient power networks in the world and, while 
we recognise the disruption that the outage caused, our systems 
performed as they should. We have worked closely with Ofgem, 
the government, the wider energy industry and other sectors like 
transport to learn the lessons from this incident. 

On 1 April 2019, National Grid ESO became a separate legal entity 
within the National Grid Group. The major programme to achieve this 
saw the creation of the NGESO Board, which includes three 
Non-executive Directors and the creation of a new office space, 
physically separate from other parts of National Grid. Following 
separation, we moved the GSO function to become part of the GT 
business to further simplify our structure and to provide greater clarity. 
We will continue to regularly review the way we are structured to make 
sure we are delivering the best possible service for our customers.

Highlights
In the US, in 2019/20 we improved our storm restoration efforts, 
successfully replaced hundreds of miles of leak-prone pipe in our gas 
network, exceeded our electric vehicle charging deployment goals 
ahead of schedule, reached record-setting Distributed Generation (DG) 
in Rhode Island, and renewed our focus on safety culture. 

The clean energy future continues to be a focus in the US. The 
Company’s net zero by 2050 announcement was in line with the 
ambitious targets and important steps being taken by governments, 
regulators and across our communities, to deeply decarbonise 
economy-wide. The US business is currently building a plan to achieve 
this new target, which will impact our fleet, building stock, and pipeline 
replacement efforts. At the end of March 2019, we had already reduced 
emissions by 71% below 1990 levels in the US, exceeding our interim 
target of 45% by 2020 group wide. We achieved this by focusing on a 
range of activities, which include a major pipeline replacement 
programme to minimise gas losses through leakage and the reduction 
of a high-emission greenhouse gas called SF6 in our electricity networks. 

An important milestone we reached, contributing to decarbonisation, 
was exceeding our electric vehicle charging station deployment goals 
ahead of schedule in New York. We enabled over 1,405 ports at roughly 
184 customer sites and have a number of customers who are eagerly 
awaiting an extension of the programme, which will be proposed to our 
New York State regulator in a future rate case.

In the renewable space, we interconnected a record number of DG 
projects for our customers in Rhode Island, totalling 99.8 MW and 
connecting 1,938 applications.

Safety continues to be a critical pillar of our daily operations. The Company 
is fully committed to the well-being and safety of our workforce and 
customers alike. This year, a tragic event took the life of one of our 
employees and reminded us to continue striving to ‘find a better way’ 
to improve our safety culture. As at 31 March 2020, our LTIFR was 0.16. 
We have focused safety culture transformation programmes to engage 
our workers on hazard and risk awareness, and required controls to 
prevent safety incidents. We have asked our workforce to direct their 
attention to the safety of themselves and their colleagues every day. 

Optimise performance
During 2019/20, the US business focused on growth, customer value, 
and deep decarbonisation. Our US Regulated net revenue was 
£123 million (2%) lower, with £257 million of incremental rate cases and 
£85 million of exchange rate benefit, more than offset by £465 million 
adverse timing (lower volumes and commodity recoveries). We invested 
£3.2 billion in energy infrastructure and technology solutions during the 
year. We also added 41,043 active new customer accounts across gas, 
electric and DG combined. 

Our energy infrastructure investments are designed to bring cleaner 
energy to our customers and enhance reliability. One of our larger 
investments, The Metropolitan Reliability Infrastructure Project, will 
increase system reliability and operational flexibility of the existing 
transmission system in Brooklyn, New York. It will also increase supply 
diversity options and provide capacity for operation in case there is an 
outage. The project consists of roughly 40,000 feet of transmission main 
that will connect the Southern line to the Brooklyn Backbone and our 
Greenpoint Facility by autumn 2021.

Through our gas pipeline replacement programme, we have 
successfully replaced 460 miles (740 kilometres) of pipe in 2019/20, 
compared to 400 miles (644 kilometres) in 2018/19. By replacing 
leak-prone pipe, we are significantly reducing unintended release of 
natural gas, reducing methane emissions and keeping our customers 
and communities safe. An innovative robotic sealing technique has 
helped us to seal cast iron pipes in congested urban areas like Boston 
and New York City. We are on schedule to replace our leak-prone pipe 
inventory across the US enterprise within the next 20 years.

A challenge we are currently facing that came to the forefront in 2019/20, 
is significant growth in demand for natural gas across our service area 
in New York City and Long Island. That growth is expected to continue 
over the next 10 years due to increased demand from new construction 
and conversion of oil to natural gas. As a solution to the gas supply 
issue, we supported the NESE Pipeline project to meet increased 
demand. When NESE was not approved by New York State, we ceased 
to connect new customers to gas in order to ensure we could continue 
to deliver gas to our existing customers safely and reliably. The New York 
Public Service Commission ultimately ordered us to connect some of 
those new customers, which we accomplished by increasing use of 
temporary supply solutions. We are now working with New York State, 
our stakeholders and our customers to find long-term solutions to gas 
supply constraints in the region. 

In 2019, we experienced an unprecedented gas supply disruption on 
Aquidneck Island that required temporarily stopping service to about 
7,500 customers. This was caused by a reduction in transmission flow 
coming into our system in Rhode Island. Since then, we have been 
working hard to learn from the event and have cooperated with a federal 
investigation and the Division of Public Utilities and Carriers in a summary 
investigation. The Division’s report, released in autumn 2019, reflected 
National Grid’s fundamental commitment to safety and exemplary 
emergency response. We have already addressed many of the proposed 
recommendations included in their report, securing additional winter 
gas supply, expanding our energy efficiency and demand response 
programmes and improving long-range planning. We now remain 
focused on securing the ongoing needs of Aquidneck Island and 
Rhode Island’s energy future.

Strategic Report | Principal operations – US

Customer first
As noted in the CEO review, at the end of 2019/20, we identified new 
ways to put the customer first in the face of the COVID-19 pandemic. 

Our unwavering commitment to our customers was demonstrated 
by a few initiatives designed to make it easier for our customers to 
do business with us. We converted more customers to paperless 
billing by improving our paperless capabilities, strengthened our online 
marketplace where customers can purchase energy efficiency and 
smart home products, increased the speed at which we verify our 
customers’ identity who call into the customer service line, and 
improved estimated time of restoration calculations during storms.

Our proactive outage communications and our Interactive Voice 
Recording upgrades increased our customer satisfaction scores, 
while storms and challenges with gas shortages in Rhode Island and 
downstate New York have caused some headwinds. As a result, 
customer ease has remained relatively flat and improvements in trust 
have increased slightly. 

We continue to work towards quick and efficient storm response to 
improve these scores. We have improved our restoration efforts over 
the past decade by developing an emergency response team that 
works hard to service our customers. The team focuses on forestry, 
staging crews, materials, advanced analytics and reporting tools, 
while employing a classification index that anticipates restoration 
times based on storm types. We demonstrated efficient and successful 
storm response in April 2020 when 70 mph+ winds caused power 
outages for over 200,000 customers across all of our jurisdictions.

National Grid has a long history as a leader in economic development, 
investing in the communities across our territory. We have seen 
record-breaking economic development grant activity in New York over 
the past five years. We help our customers evaluate infrastructure needs 
and improve productivity, efficiency and profitability so that they remain 
and grow in the region. 

The town of Lima, New York, recently experienced a significant 
economic boost with the expansion of Bristol ID Technologies creating 
new jobs within this rural community. The Company’s electric capital 
investment grant provided $118,000 to help offset the new electric 
infrastructure required for this impactful business expansion, resulting 
in higher-volume production at a reduced cost and more clients.

Grow core business
In September, the Massachusetts Department of Public Utilities (MADPU) 
approved an electric rate case, which enables us to deliver on important 
investments in reliability and storm response, provide greater assistance 
to income-eligible customers and support electric transportation and 
energy storage policies that are helping drive us towards a clean energy 
future. The Company had not updated its rates since 2016 and will not 
file a new rate case for Massachusetts Electric until 2023. 

In December, our Rhode Island Gas and Electric Infrastructure, Safety, 
and Reliability (ISR) plans were filed with the Rhode Island Public Utilities 
Commission (RIPUC). The plans provide mechanisms to fund maintaining 
and upgrading the gas and electric distribution systems by replacing aging 
equipment, addressing load growth, and responding to emergencies. 
In addition, the Gas ISR plan allows for proactive replacement of 
leak-prone pipe. Both of these plans were approved by the RIPUC in 
March 2020.

In the latest gas rate case, filed April 2019 for KEDNY/KEDLI, the 
Company proposed a suite of demonstration projects to explore 
low-carbon heating solutions. The solutions are divided into programmes 
or technologies. The rate case is still underway. Over the past year, we 
have taken meaningful steps to develop low-carbon heating solutions. 
In coordination with all New York’s gas utilities, we have developed the 
RNG Interconnection Guideline. RNG is pipeline-compatible, gaseous 
fuel with lower lifecycle carbon dioxide equivalent emissions than 
geologic natural gas. The purpose of the guideline is to provide a 
necessary technical framework that can incorporate RNG into the 
natural gas distribution network.

Evolve for the future
Over the past few years, the Company has been hard at work 
decarbonising the transportation sector. 

In partnership with the Capital District Transportation Authority, National 
Grid deployed four electric public buses in Albany, New York. National 
Grid and the transportation authority will monitor the range, charging 
timelines, electricity usage and performance of the vehicles throughout 
its route network. If the demonstration proves to be successful, the 
Company will work with other transportation authorities to deploy more 
electric buses across the region. 

In upstate New York, National Grid’s EV charging programme surpassed 
its EV charging installation goal. The Company originally planned to 
complete 56 projects through this programme with an approximate 
$3 million allocation. However, we have more than tripled that goal with 
the completion of over 184 projects. Over 40 of the programme’s site 
hosts serve disadvantaged communities.

Looking ahead
In 2018/19, the Company announced the Accelerate Programme, 
an ambitious, three-year efficiency challenge that set out an aspirational 
target of a 20% efficiency improvement in operational and capital 
expenses across the US business by 2020/21. The Accelerate Programme 
is aimed at improving both the quality and cost-effectiveness of our 
services to customers. This programme will continue to allow us to find 
a better way, so we can grow and serve customers long into the future. 
As we forge ahead into our clean energy future, we continue to identify 
pathways for deep decarbonisation along with the states we serve, 
focusing on the power, heat and transportation sectors. As one of the 
world’s largest investor-owned utilities, we will work alongside 
policymakers to ensure we can deliver clean, safe, reliable and 
affordable energy to customers today and tomorrow.

Highlights 
This section relates to NGV, non-regulated businesses and other 
commercial operations not included within the business segments. 

NGV, which operates separately from our core regulated units, is focused 
on investment in a broad range of energy businesses that operate in 
competitive markets across the UK and US. Its portfolio includes 
electricity interconnectors, LNG storage and regasification, energy 
metering, large-scale renewable generation and competitive transmission. 

Our ‘other’ activities comprise NGP, the venture investment and 
innovation arm of National Grid plc, as well as UK property and US 
non-regulated businesses, which include LNG operations and 
corporate costs. 

In aggregate, the NGV and other segment delivered £237 million of 
statutory operating profit, £242 million underlying operating profit and 
accounted for £885 million of continuing investment in 2019/20. 

As at 31 March 2020, our LTIFR was 0.05. This is better than our NGV 
target of 0.08.

Operational performance 
Electricity interconnectors: NGV is the leading developer and operator 
of electricity interconnectors to and from the UK. NGV’s operational 
portfolio currently comprises 4 GW of interconnector capacity. 

BritNed is an independent joint venture between National Grid and 
TenneT, the Dutch transmission system operator. It owns and operates a 
1 GW HVDC link between GB and the Netherlands. In 2019/20 BritNed’s 
availability was 98.6%. 

The England-France interconnector (IFA) is a 2 GW HVDC link between 
the French and British transmission systems, with ownership shared 
between National Grid and Réseau de Transport d’Electricité (RTE). 
In 2019/20, IFA’s availability was 91.4%. 

Nemo Link is an independent joint venture between National Grid and 
Elia, the Belgian transmission system operator. It owns and operates 
a 1 GW HVDC link between GB and Belgium. Nemo Link’s availability 
was 96.1% in 2019/20.

LNG storage and regasification: Grain LNG is one of three LNG 
importation facilities in the UK. It operates under long-term take or pay 
contracts with customers and provides importation services of ship 
berthing, temporary storage, ship reloading and regasification into the 
NTS. Utilisation of terminal capacity was 30.8% in 2019/20, up from 
18.8% in 2018/19. Grain LNG set a record for the highest single-day 
gas send-out from a European terminal in November 2019.

Grain LNG’s road tanker loading also offers the UK’s transport and 
off-grid industrial sector a more environmentally friendly alternative to 
diesel or heavy fuel oil. The facility allows tanker operators to load and 
transport LNG in bulk across the UK via road or rail. 

UK metering: National Grid Metering (NGM) provides installation and 
maintenance services to energy suppliers in the UK’s regulated market. 
It maintains an asset base of around 8.8 million domestic, industrial and 
commercial meters, down from 9.9 million in 2018/19.

US competitive transmission: NGV is a part-owner of Millennium 
Pipeline, which provides consumers in the northeastern US with 
additional natural gas infrastructure to meet growing demand for cleaner 
and more reliable energy. It is strategically positioned to serve utility and 
power plant loads across New York State and into New England. 

NGV is also a part-owner of New York Transco, which energised three 
new transmission upgrade projects in New York in 2016 that provide 
several ongoing benefits, including reducing upstate to downstate 
transmission congestion to save money for electricity consumers and 
offering better access to clean energy, and supporting the retirement 
of traditional power generation. The assets include the Ramapo to Rock 
Tavern 345 kV Line, Frasers-Coopers Corner 345 kV Line and Staten

National Grid Property entered into a new joint venture agreement with 
Places for People, one of the largest regeneration, development and 
property management companies in the UK and a registered provider 
of affordable housing. As part of the venture, we aim to build up to 500 
new homes on the first three sites, and delivering 10 sites into the joint 
venture over the next three years.

Evolve for the future 
UK Carbon Capture, Utilisation & Storage (CCUS): In 2019 NGV 
launched Zero Carbon Humber, a consortium looking to develop the 
world’s first zero-carbon industrial cluster in the UK’s Humber region 
by 2040. Such a project would protect 55,000 jobs in the region and 
establish the UK as a world leader in CCUS technology. 

US offshore wind: Ørsted and Eversource, with support from NGV, are 
developing the Revolution Wind offshore wind farm which was awarded 
competitive tenders to supply electricity to distribution utilities in Rhode 
Island and Connecticut. The proposed 704 MW wind farm will be 
located over 15 miles (24 kilometres) south of the Rhode Island and 
Massachusetts coasts. The project is expected to be operational by 
2023, pending permits and final investment decisions. NGV has the 
option to acquire the transmission connection between Revolution Wind 
and the onshore electric transmission network.

National Grid Partners: NGP is the venture investment and innovation 
arm of National Grid. NGP’s portfolio at the close of the fiscal year 
comprises 21 companies at a fair value of £134 million.

US battery storage: NGV is a 50-50 joint venture partner with NextEra 
Energy Resources in two battery energy storage systems on Long 
Island. These include two 5 MW, 40 MWh battery energy storage 
systems in East Hampton and Montauk, New York. The batteries have 
helped decrease emissions and enabled energy peak-shaving during 
the busy summer months on the eastern end of Long Island.

UK property: National Grid Property deals with the management and 
regeneration of our brownfield surplus estate in the UK. Our specialist 
team works with our communities to return these redundant sites back 
into beneficial use to provide new homes and employment opportunities 
across the UK.

In 2019/20, we disposed of 34 sites and exchanged contracts on a 
further five land sales, to facilitate the delivery of thousands of new 
homes across the UK. Our joint venture with Berkeley Group, called 
St William Homes, has entered its sixth year and recorded its first profit 
in 2019/20. Around 7,600 homes are already under construction 
across London and the South East. 

Grow core business 
Electricity interconnectors: NGV will grow its interconnector portfolio 
by 3.8 GW in the next four years, with new subsea power links to France, 
Norway and Denmark. 

Construction continues on the 149-mile (240-kilometre) IFA 2 
interconnector. Developed with RTE, the 1 GW subsea cable will connect 
Great Britain and France. The link is expected to be operational in 2020. 

North Sea Link (NSL) will connect Great Britain and Norway. Developed 
between National Grid and the Norwegian transmission system operator 
Statnett, NSL will be 447 miles (720 kilometres). The 1.4 GW link is 
expected to be operational in 2021/22. 

Preliminary construction works have now also commenced on the 
Viking Link interconnector. Developed together with Danish transmission 
system operator Energinet, Viking Link will be a 1.4 GW 472-mile 
(760-kilometre) long subsea link connecting Great Britain and Denmark. 

NGV will have 7.8 GW of operational interconnector capacity when 
Viking Link becomes operational in 2023/24. 

US large-scale renewables: NGV completed its acquisition of 
Geronimo, a leading wind and solar developer in North America based 
in Minneapolis, in July 2019. Since the acquisition, National Grid has 
announced the commercial operation of its 200 MW Crocker Wind Farm 
in South Dakota, along with the signing of a Power Purchase Agreement 
with Basin Electric Power Cooperative for its 128 MW Wild Springs solar 
project, also in South Dakota. These developments, together with further 
activities that build on their strong pipeline of future renewable energy 
projects, complement the 379 MW portfolio of operational wind and 
solar assets which are held in joint venture with Washington State 
Investment Board and operated by National Grid.

US competitive transmission: In April 2019, New York Transco’s 
New York Energy Solution (NYES) was selected by the New York 
Independent System Operator to provide transmission upgrades that 
will relieve congestion of New York’s bulk electric power system, while 
enhancing reliability and facilitating upstate clean energy resources to 
the downstate demand centers. The upgrades will be taking place on an 
existing 54.5-mile (88-kilometre) utility corridor and on utility-owned land. 
New York Transco is well into the consenting and permitting process for 
the NYES project, which remains on track for a late 2023 service date. 
NGV expects to participate in additional public policy electric transmission 
projects in New York that will be necessary to accommodate increasing 
amounts of renewable energy, in particular offshore wind.

UK property: St William continues to grow and we now expect the 
joint venture to deliver around 20,000 new homes across London and 
the South East. A further four sites have been negotiated into the joint 
venture during 2019/20 with further sites expected to be negotiated into 
the joint venture during 2020/21. In the next 12 months, we expect our 
St William Homes joint venture to complete construction of over 100 
new homes across London.

Strategic Report | Our stakeholders

How we create value for our stakeholders

The long-term success of our business is critically dependent on the 
way we work with a large number of important stakeholders. We aim 
to create value for our stakeholders every day by maintaining levels of 
business conduct that are governed by our values. We continue doing 
so as the energy landscape changes. 

How our Board keeps up to date with stakeholder interests
Reporting and monitoring: Our Company-wide engagement collates 
information on stakeholder interests that informs business-level 
decisions, with an overview of developments being reported on a 
regular basis to the Board or a Board Committee. In some cases, this 
will be through an annual or more frequent round-up for the business 
area interfacing with the relevant stakeholder (this is generally the case 
for customers and suppliers). 

Direct engagement: In other instances, one or more members of the 
Board may be involved directly in the engagement (such as shareholder 
or other investor networking). In each case, it is important for all members 
of the Board to gain sufficient understanding of the issues relating to 
every stakeholder, so their views are taken into account in Board discussions. 
The table below sets out our focus on the key relationships and shows 
how the relevant stakeholder engagement is reported up to the Board 
or Board Committees to help inform decisions made by Directors. 

We have provided some examples of how particular engagement 
outcomes were considered by the Board below, noting that these 
examples are not exhaustive in summarising all our stakeholder 
considerations. Within each example, when outlining how the Board 
considered the impact on a particular stakeholder group, we also list 
the broader range of stakeholders the Board considered as part of 
its discussions. 

We considered the interests of our stakeholders in reviewing matters 
such as our liquidity and financial arrangements, our dividend, 
operational matters, for example resolving the gas supply issues in 
New York City and Long Island and developing our business plans. 
You can also read more about how the Board showed regard for the 
interests of various stakeholder groups through a worked example of 
its response to the COVID-19 pandemic on page 65.

This section, How we create value for our stakeholders, serves as our 
section 172 (1) statement.

Company engagement
The Company Secretariat team, together with the Company’s 
Registrar, engage with our retail shareholders throughout the year 
to deal with enquiries relating to shareholdings.

Board-level engagement
Updates from Company-level engagement with shareholders 
are provided to the Board as appropriate.

The AGM and shareholder networking programme provide the 
Board with valuable opportunities to engage with our shareholders. 
All members of the Board attended the 2019 AGM to discuss 
proposals and answer shareholder questions as necessary. The 
shareholder networking programme in 2019 included presentations, 
and a visit to our Gas National Control Centre in Warwick where 
shareholder attendees had direct one-to-one contact with senior 
management, Board members and engineers across a two-day period.

During the shareholder networking programme and 2019 AGM, the 
Board members listened and responded to views of our shareholders. 
Any resulting actions were fed back to the businesses as necessary.

We recognise the importance of keeping an engaged shareholder 
base so that we can closely monitor their interests. As such, the 
Company Secretariat team, in collaboration with our Registrar, 
implemented an asset reunification programme in January 2020. 
This exercise provided us with an opportunity to re-unite as many 
shareholders as possible with their unclaimed assets. The 
programme will continue throughout 2020 and so far, as at 30 May 
2020, £13 million was reunited with the respective shareholders 
and we have re-engaged 8,372 shareholders on the register.

Ongoing engagement between our investors and the political 
sub-group of our Executive Committee highlighted concerns 
around the UK Labour Party’s policy for state ownership of the UK 
operating companies. The Board, in line with its fiduciary duty to 
its shareholders, took steps to protect the value of shareholdings 
in the event of UK state ownership.

Company engagement
Over the year, the Investor Relations team held 436 investor 
meetings across 10 countries and 26 cities: met with over 400 
institutions, representing 49.9% of our share register; and hosted 
three site visits, offering investors the opportunity to meet divisional 
management and view our assets.

The investor perception study highlighted that senior management 
was held in high regard and that the ability to maintain operational 
excellence is taken for granted. The survey further noted that there 
was an opportunity for the Company to raise the profile of the role it 
is playing in the energy transition and also emphasised the strategic 
benefits of the combination of the Company’s UK and US assets.

Our engagement programme focuses on updating investors on 
the regulatory and operational progress in our UK, US and NGV 
businesses, as well as the growth opportunities available to us. 

During the year, the Debt Investor Relations team in Treasury held 
meetings between senior Group Treasury representatives and debt 
investors in the UK, Continental Europe and the US. Topics 
covered included our financial results, US rate case filings and 
bond issuance. The team also met with debt investors at various 
conferences over the course of the year.

Board-level engagement
The Board received regular feedback on investor perceptions 
and opinions about the Company and as part of our engagement 
programme we provide the opportunity for our current and 
potential investors to meet with the Chairman, the Executive 
Committee and operational management. 

Additionally, the Board received the results of an independent 
audit of investor perceptions where interviews were carried out 
with investors to establish their views on the performance of the 
business and management. The findings and recommendations 
of the audit were then reviewed by the Board. 

Our investors also expect that we stand for something far more than 
providing economic returns. To facilitate the change towards net 
zero, in January 2020, we also announced the launch of our first 
green bond, issued by National Grid Electricity Transmission plc. 
The €500 million proceeds from the bond issuance will finance 
electricity transmission projects with environmental benefits. 

An ESG data book was published in the year to measure the overall 
performance of the Company in operating responsibly, while 
creating positive social impact. In preparing this data book, we held 
discussions with investors to identify the most commonly used ESG 
data providers, and reviewed these questionnaires to determine the 
most relevant data to communicate to investors. During this process 
over 400 questions were reviewed. Subsequently, these were 
consolidated and refined down to those included in this document.

Company engagement
Engagement with our people takes many forms, including 
reviewing and implementing actions from the EES results; 
Employee Resource Group (ERG) sessions, which provide the 
opportunity for ERG chairs and leads to discuss the importance 
and impact of their group and provide valuable feedback on 
inclusion and diversity related topics; meetings with trade union 
representatives, and leadership offsites located at a range of 
different business locations in the UK and US.

Board-level engagement
The annual EES provides senior leaders and the Executive Committee 
and Board with an insight into how our employees are feeling about 
the Company and its direction. Action plans are developed to 
progress any areas of improvements that are identified. 

The Board also conducts site visits and meets with a wide range 
of employees through our employee engagement programme: 
you can read more on this on page 73. 

The Executive Committee also received regular talent updates 
and considered the remuneration structure for senior management. 

Company engagement
UK – regular interactions with Ofgem and the Health and Safety 
Executive. The Company also organises stakeholder fora and 
consultations with stakeholders, including members of the public, 
our suppliers and customers around specific projects and 
proposed business plan submissions for RIIO-2. 

We work with other networks and organisations outside of the 
energy industry to identify good practice. 

US – regular interface with both federal and state regulators and 
customers on an ongoing basis, as well as the pre-filing 
stakeholder engagement programme in the build-up to and during 
any rate case process. Specific engagement was undertaken 
regarding the decarbonisation pathways and the Niagara Mohawk 
Power Corporation advanced metering infrastructure. 

Board-level engagement
The Board met with the Chair, CEO and incoming CEO of Ofgem in 
November 2019. The topics of conversation included our net zero 
ambition, with a focus on practical solutions to move the agenda 
forward. The discussions also covered RIIO-2. 

The outcomes of engagement activities are reported to the 
appropriate forum and ultimately to the Executive Committee and 
Board. In the US, any rate case engagement is reported up to the 
Executive Committee and the ordering of Executive Committee and 
Board as appropriate.

The Board met with the Governor of Massachusetts and a member 
of the Governor’s office in March 2019. Recognising the severity of 
the adverse reaction of various stakeholders to the gas moratorium 
that was enforced by the Company in downstate New York, the 
Board commissioned two external reviews to understand how the 
US business had made the original decision. Long-term solutions 
are being implemented.

The topics discussed and actions from Board and Executive 
Committee’s engagement with our people can be found on page 73.

The Board was pleased to see a continued improving trend in 
overall employee engagement through the 2020 EES results. The 
introduction of the Leadership Index has allowed leaders to gain 
feedback from their direct reports on areas where their personal 
actions, style and behaviours can have an immediate impact on 
enablement and engagement. The Leadership Index will be a key 
focus area for 2019/20.

In the UK, discussions with our regulators have contributed to the 
productive outcome of key business issues such as:
•  the 9 August 2019 power outage: the Company had regular 

engagement with Ofgem and the UK government, and the Board 
regularly discussed the outcome of investigations and reports 
focused on this, including the response to Ofgem on the findings 
from the investigation. In January 2020, the Board welcomed 
Ofgem’s report on this incident which confirmed that our actions 
did not cause the outage.

•  the future of our ESO business, which will be reviewed by Ofgem 

following legal separation last year. 

•  RIIO-2 business plans: for the development of the RIIO-2 

business plans, we have followed Ofgem’s enhanced stakeholder 
engagement process, which is based on greater engagement 
with our industry and end consumers to prioritise their needs in 
our RIIO-2 business plans. Three independent groups were 
established to provide challenge throughout this process – two 
independently Chaired User Groups, (one for the ESO and one for 
the transmission businesses) and an Ofgem Challenge Group. 
Regular discussions were held at the Executive Committee and 
the Board on progress with stakeholder engagement, the 
development of the RIIO-2 business plans and on interactions 
with the challenge groups. On invitation, the Chairs of the Chaired 
Independent User Groups met with the Board in 2019.

Following a period of engagement with Ofgem, we submitted 
our final business plans for RIIO-2 in December 2019. Thereafter, 
engagement has continued with Ofgem evidencing various aspects 
of the Company’s RIIO-2 business plans such as the formal 
question and answer process to explore our RIIO-2 business plan 
submission ahead of its draft and final determinations later in 2020.

In the US we refined the Company’s regulatory strategy and 
business planning for rate cases and other US regulatory priorities. 
The Company’s rate case pre-filing stakeholder engagement 
programme has become a major contributor to the Company’s 
successful rate case outcomes.

The external reviews conducted on the gas moratorium have 
highlighted lessons and recommendations which are already being 
implemented. In the short term, all affected customers have been 
contacted and plans are in place to make sure that they are 
connected to a gas supply in the near future. Medium- to long-term 
solutions that are in the best interests of our customers and 
regulators continue to be progressed. The Board is closely 
monitoring the output of these developments.

Communities 
and 
governments 

Policy and public affairs and in house US government relations teams 
develop, grow and leverage the Company’s relationships with key 
politicians, officials, wider stakeholders and influencers to ensure the 
Company is connected with legislation and government policy.

Our customers 

Engagement with local communities in the form of consultations 
during construction phases of projects and work with 
environmental education centres. 

We liaise with land owners and wider communities where the 
Company has assets and we have established dedicated teams 
to manage relationships.

Board-level engagement
During the year, the Board received regular updates on the 
potential impact of renationalisation which had been included as a 
policy in the Labour Party manifesto ahead of the December 2019 
UK General Election. Regular updates were also received in relation 
to Brexit. 

The downstate New York gas moratorium and feedback from 
engagement with the Governor of New York formed an important 
part of the Board’s agenda for the US business.

Company engagement
UK customer programme – we use several channels such as 
operational fora, liaison meetings, market research, stakeholder 
events and interactive customer listening sessions to engage with 
our customers. We have in place a robust governance structure 
to ensure our engagements and insights are shared at all levels. 
This includes a strategic meeting accountable for customer and 
stakeholder experience across the UK core business. It is chaired 
by our UK Executive Director and attended by the UK Executive 
Committee members on a quarterly basis. To support this, we have 
a committee made up of senior leaders from across the UK 
business. This governance is designed to ensure our pipeline of 
work addresses customer needs and continuously raises the bar. 
We also ensure customer experience remains one of our top 
priorities by measuring and tracking progress against our customer 
experience strategy throughout the Company.

US customer team – collects and communicates 
‘voice of customer’ feedback throughout the business, gathered 
via customer surveys on a tracking and ad hoc basis to measure 
customer sentiment of residential, commercial and wholesale 
customers. An online community of 6,000 residential customers 
enhances insight with fast and continuous feedback. We are also 
leveraging design to inform customer experience solutions, 
process changes and product development.

Board-level engagement
In the year, the Board received updates on both the UK and US 
customer strategies. Bi-annual reports were also submitted to 
the Board from the UK, US and NGV businesses. 

Company engagement
Strategic relationship meetings are conducted regularly between 
suppliers and the procurement team.

Our suppliers

We work closely with our suppliers and peers to build on our 
knowledge and promote best practice in the industry to combat 
issues such as climate change.

Board-level engagement
Bi-annual reports relating to our suppliers were submitted to the 
Executive Committee and annual reports to the Board. 

The Board agenda continued to be strongly focused on community 
and governmental issues this year such as:
•  the December 2019 UK General Election and the resulting exit 

from the European Union on 31 January 2020. We have continued 
to work with our UK regulators and the UK government to ensure 
that free trade agreements are negotiated for our interconnectors 
so that consumers continue to reap their benefits. We have also 
looked after the interests of our European staff and sought to 
ensure continued co-operation in energy balancing across 
Europe in the future.

•  in the US, the impact on communities following the gas 

moratorium in downstate New York was considered in depth by 
the Board and the Safety, Environment and Health Committee. 
We progressed dialogue with the New York State Governor and 
enacted settlement agreements and are now developing 
long-term solutions.

•  the clean energy agenda: UK and US governments and 

communities are strongly focused on carbon reduction activities. 
To focus on meeting our net zero commitment and embedding 
sustainability into our culture, we applied a sustainability lens 
across our operations and challenged our businesses to commit 
to challenging targets. In the US, at the state level, we have strong 
alignment with policymakers and regulators who, like us, are 
committed to a cleaner energy agenda. In the UK, we continue 
to work to maintain access for customers to european energy 
that is affordable and renewable, and the Board also approved 
the Company’s announcement of its target to become carbon 
neutral by 2050.  

Views of other stakeholder groups considered
Customers, Investors, Regulators, Suppliers, Our colleagues

In the UK, feedback received through our stakeholder-led RIIO-2 
business plan provided an understanding on how satisfied our 
customers are with the service we provide. Their views on the 
outputs we should provide during RIIO-2, how these should be 
delivered and the effect on their bills, were considered by the Board. 

In the US, we have incorporated ‘voice of the customer’ in Executive 
Committee and Board papers and received feedback to support our 
five new strategic imperatives which will guide our customer focus.

The Executive Committee and Board also received updates on the 
US KEDNY/KEDLI and Niagara Mohawk rate case filings.

In collaboration with our suppliers, our focus is on delivering 
low-carbon and sustainable schemes for our projects. We 
established major contracts that will support our role in accelerating 
the clean energy transition. For example:
•  the Board were updated on the six-year, £400 million contract 

with Hochtief-Murphy Joint Venture, who will deliver the tunnelling 
and shaft work for the London Power Tunnels 2 project; and
•  the Board received an update on the chosen supplier, Balfour 

Beatty, who had been chosen to be the civil works supplier for the 
Company’s interconnector to Denmark. The four-year, £90 million 
contract will deliver the British onshore civils works for the project.

Strategic Report

Our commitment to being  
a responsible business

In 2019, National Grid conducted a 
comprehensive review of where we can 
create the most positive impact on society. 
The resulting principles of responsibility 
are being embedded to inform everything  
we do as a business. 

Responsibility at National Grid
Our purpose is to “Bring Energy to Life” and we do this through the 
delivery of the electricity and gas that powers our customers and 
communities; safely, reliably, and efficiently. But we also have an 
important role as a responsible citizen in society as a whole, in our 
communities, and as a responsible employer. 

To further this ambition, during 2019/20 we applied the lens of being a 
purpose-led organisation, including the principles of an ESG (Environmental, 
Social and Governance) framework, to review and adapt the way we 
manage our business responsibly, looking at everything from our strategic 
investment process, to our role in the community, to our procurement 

processes and policies. This brings together, and enhances, our focus 
on the environment, people and communities that have been at the core 
of our approach to responsible business for many years.

We have committed to embedding the following five key elements of 
being a responsible business into our strategy and goals. These are 
areas where the Company can create maximum total societal impact: 
the environment, our governance, our colleagues, the communities 
we serve and operate within, and the economy. 

This approach has informed and guided our response to the COVID-19 
crisis, with a focus on caring for our colleagues, supporting the 
communities and customers we serve, and helping protect and 
restore the economies we operate within.

Our approach to reporting 
This section contains information relating to the key focus areas that are 
considered material to shareholders, as identified by our internal review 
of total societal impact.

We have rigorous policies in place that support our approach to 
corporate responsibility and we report on a number of non-financial 
performance measures relating to these policies. 

Our principles of responsible business

Governance

Ensuring that our governance 
mechanisms reflect our 
commitments and ensure that 
the principles of responsibility 
guide us in everything we 
do as a business.

Our communities

and affordably; ensuring  
they get the benefits.

National Grid plc Annual Report and Accounts 2019/20

Strategic Report | Our commitment to being a responsible business

Our communities 
We are committed to delivering sustainable energy safely, reliably and 
affordably for the communities we serve. In 2019 we recognised the 
importance of ensuring that our communities enjoy the benefits of 
the clean energy transition and that no one should be left behind in 
delivering those benefits. 

These shifts in our sector will require investment. We are committed to 
working with the communities we serve to help them meet, or exceed, 
their overall climate and carbon ambitions, and we will look to do so in 
an affordable way. As we develop long-term affordability targets, we 
will ensure that National Grid’s cost to our customers is reported 
transparently on an annual basis.

As well as affordability, the principle of fairness is also important. We 
will play our role in ensuring that no-one is left behind in the transition to 
clean energy, and that the associated benefits are enjoyed by all. A fully 
decarbonised transportation infrastructure, for example, should be 
accessible by everyone across the communities we serve. 

Finally, we embrace our responsibility to maintaining the delivery of energy 
to the communities we serve, safely and reliably. 

Engaging with our communities
We regularly seek feedback from our customers to find out what they 
think of us and the services we provide, and take the appropriate action 
to improve and exceed customer satisfaction. You can read more about 
our customer satisfaction performance on page 18. 

Supporting communities to thrive 
Responsibility in our communities means safely maintaining the resilient 
energy systems society expects and has become accustomed to, as 
well as ensuring that our economic and social role in the community has 
the greatest possible positive impact. That’s why we partner with charity 
organisations and encourage and enable our employees to volunteer to 
work with them. In early 2020 we launched a Company-wide community 
investment strategy to ensure that our programmes enable skills development 
with a focus on lower-income communities. These programmes are 
intended to create employment opportunities in the energy sector, related 
to the clean energy transition. We are committed to tracking programme 
participants from initial interaction all the way through to eventual 
employment either at National Grid, our partners, suppliers or other 
organisations involved in the challenge of meeting net zero. Our goal is 
to create 45,000 jobs across the US and UK through this new initiative.

Case study – UK
The Hinkley Connection Project
Our project will connect the UK’s first nuclear power station for a 
generation; introduce T-pylons to our network; and release low-carbon 
and renewable energy from the south west. It’s a positive and exciting 
future. Getting there, however, means impacting communities with 
construction for seven years. 

In return, we’re helping local people create a future of their own and are 
investing in the local economy via adult skills and employment. Working 
with stakeholders we have created bespoke training and support for the 
long-term unemployed. Our aim is to help more than 300 long-term 
unemployed into work; so far, 49% of those under training have gained 
employment.

We listened to government agencies, local authorities, job centres and 
charities – as well as our customer, EDF. Their feedback helped us 
design a course that responds to local labour markets and, with retention 
a key challenge, encourages trainees to complete it. Based on 
stakeholder feedback, we emphasised traffic management training.

Stakeholders challenged us to focus training in areas most affected by 
construction and we are now revisiting our approach. 

Through our commitment to benefit the communities in which we 
operate, we are connecting with people, as well as low-carbon 
generation, leaving a legacy of job creation and upskilling.

“In early 2020 we launched 
a Company-wide community 
investment strategy to 
ensure that our programmes 
enable skills development 
with a focus on lower-income 
communities.”

Contribution of our corporate 
responsibility work

Part of our responsibility is to serve society fairly and affordably. In the US 
we already care for vulnerable customers with low-income programmes, 
bill discounts and free energy efficiency advice. In response to the COVID-19 
crisis, we have expanded customer support, paused late payment 
collections activities, and placed a freeze on related service cutoffs.

In the UK, National Grid established a £150 million Warm Homes Fund. 
This is the largest private sector investment in energy efficiency ever 
made in the UK, and is designed to support local authorities, registered 
social landlords and partnerships to help approximately 50,000 
households suffering from fuel poverty. Protecting vulnerable customers 
remains a key priority as we seek to ensure that no-one gets left behind 
in the transition. And by engaging with customers to reduce their energy 
usage, we can also help them reduce their carbon emissions, 
contributing to the overall decarbonisation of the economy. 

Reliability and resilience are part of our regulatory duty, but also our social 
contract. There isn’t a choice between a clean energy system and a 
reliable one. Due to the effects of climate change, we expect our network 
will need to be more prepared to recover from extreme weather events, 
and we are committed to ensuring the reliability of supply, as well as 
playing a leading role in disaster recovery.

Case study – US
Ideal Dairy Farm, New York
The New York State Energy Research and Development Authority and 
National Grid work collaboratively to deliver technical and financial 
resources to the agriculture community across New York State. We are 
pleased Ideal Dairy, LLC has been a beneficiary of this scheme.

Energy costs are a significant expense for a farm. Expansion has always 
been part of Ideal Dairy farm. Recognising the importance of greater 
economies of scale, Ideal Dairy decided to proceed with a multi-million 
dollar expansion project. National Grid provided financial incentives for 
the energy-efficient equipment as well as an economic development 
grant for a new commercial underground three-phase 1,600 amp service 
to support this expansion. The new well-lit parlour and barns with 
efficient ventilation systems keep the areas bright and comfortable for  
the cows and workers. This optimises production.

Ideal Dairy has grown from 1,230 cows in 2016 to 2,300 cows while 
doubling production to 22,000 gallons of milk a day through efficiencies. 
With the success of this project, they added a freestall barn in 2019 and 
plan for another one in 2021. They anticipate this will enable them to grow 
to 3,000 cows. Through this expansion, Ideal Dairy is improving the 
environment by reducing their energy consumption, and keeping their 
workers satisfied, whilst serving their community.

Environmental: The path to net zero
We are embracing our role at the heart of the energy system and 
understand the critical role we play in tackling climate change. 
The markets in which we operate have announced ambitious carbon 
reduction targets and further legislative actions are anticipated in all 
our markets. These targets will be challenging and we embrace 
the opportunity to support the delivery of these goals. 

While the biggest impact we can have is supporting the economy-wide 
clean energy transition, it is important we also reduce our own direct 
impact on the environment. 

In 2012, we developed our environmental sustainability strategy, “Our 
Contribution”, to set a framework for embedding sustainable decision-
making into our business operations. We focused on three key areas – 
climate change, responsible use of natural resources and caring for the 
natural environment – and set targets to deliver progress through the 
end of 2020. In 2019/20, we have continued to advance our work.

We continue to focus on carbon reduction being factored into both 
our major investment decisions and our tender process for major 
construction projects. These actions encourage not only our teams, 
but also our supply chain to deliver lower-carbon solutions. Supply chain 
emissions are classified as Scope 3 emissions and, as such, the tender 
carbon weighting will help us reduce our Scope 3 emissions.

We also have programmes in place to ensure that we are making 
improvements to the natural environment. One such programme focuses 
us on finding better ways to deliver an increase in environmental benefits 
on non-operational land, while working with local partners and communities. 
Work under this programme prioritises local environmental benefits, for 
example increasing pollination, community access to green space and 
bio-diversity (see the Pollinator Meadow Project case study below).

“In 2019 we furthered our 
commitment to combating 
climate change with the 
announcement that we will 
aim to achieve net zero for 
our direct emissions by 2050.”

Case study – US
Pollinator Meadow Project – Pawtucket, Rhode Island
Our electric transmission corridors must be regularly maintained to 
prevent vegetation from endangering the wires. We see this as an 
opportunity to practise environmental stewardship. 

As meadows are becoming rare as more New England pastures grow 
back into forests, transmission line corridors are increasingly important 
as low growing-shrub and meadow habitat. To assess the viability and 
practicality of incorporating wildflower plantings into our vegetation 
management program, we implemented a pollinator pilot project in 
Pawtucket, Rhode Island. During this pilot, we converted almost two 
acres of transmission line corridor to wildflower meadow. The project 
was a success and the flowers continue to flourish. We will continue to 
monitor the project and are committed to creating at least one new 
pollinator site in the US per year, over the next five years.

Projects like these not only help the environment, but also allow us to build 
connections with local environmental organisations and customers and 
increase public understanding of our vegetation management programmes.

Case study – UK
Chairman’s Awards: Save Evie’s Whale
The annual Chairman’s Awards are a demonstration of how we use 
governance to bring our purpose, vision and values and the role we play 
in society to life. Every year more than 150 teams submit entries that 
show how the work we do at National Grid contributes positively to our 
people, our customers and communities now and in the future. 

In 2019 the “Save Evie’s Whale” campaign was chosen as the winner 
of the Chairman’s Awards at an event in New York. The campaign was 
inspired by Evie O’Grady, the seven-year-old daughter of one of our 
employees, who made a drawing of a whale – because she was so upset 
about the number of whales dying due to plastic pollution in our oceans. 
Evie’s drawing and her story became an inspiration to encourage 
employees to think about the environmental impact of single-use plastics. 
In June 2019 we made a commitment to remove single-use plastics from 
sale at our UK offices by 2020. 

The “Save Evie’s Whale” campaign brought that commitment to life and 
provided a platform to engage with employees and suppliers about 
reusable cups and other materials, and effective recycling behaviours. 
Piloted in our Warwick UK offices, with the campaign we have successfully 
eliminated plastic straws and plastic cutlery and eliminated over 46,000 
polystyrene containers and 22,000 plastic containers going into general 
waste annually. The programme also created significant cost savings by 
reducing the use of consumables, improving recycling rates, and cutting 
the volume of waste generated. “Save Evie’s Whale” has since been rolled 
out in offices across the UK, and also at local schools and community 
groups, inspiring behaviour change in society. Over 4 million pieces 
of single-use plastic have so far been eliminated.

Strategic Report | Our commitment to being a responsible business

Building on earlier actions to manage office waste, we launched waste 
reduction campaigns across our offices in the UK and the US. In the UK 
we have eliminated over four million items of single-use plastics, mainly 
related to food and beverages (see the Save Evie’s Whale case study 
on the previous page). In 2019, we also diverted 95% of office waste 
from our targeted sites away from landfill, and are aiming to complete 
work at the remaining sites in 2020.

Our Further Commitments to Reducing our Impact and
Achieving Net Zero
As we work to meet our 2020 ‘Our Contribution’ commitments, we 
will continue to reduce our carbon footprint, maximise the value of 
our resources and enhance the environment; however, we recognise 
that we can do more to combat climate change and improve the 
environment. To accomplish this, as part of our Responsible Business 
review, we are developing new metrics and targets to further challenge 
us and allow for monitoring and evaluating our performance. These will 
be announced later this year.

The cornerstone of our revised targets is our commitment to achieve net 
zero for our scope 1 and 2 greenhouse gas emissions by 2050 that was 
announced in November 2019. This replaces our previous target of an 
80% reduction by 2050 to better align with our ambitions. We also set 
more ambitious interim targets for our emissions reductions of 80% by 
2030 and 90% by 2040.

To achieve these targets, we will also progress our emission reductions 
by continuing, and accelerating, current emissions reduction 
programmes, and by looking for new, innovative ways to reduce our 
emissions. We are reducing leakage from our gas pipelines through our 
gas mains replacement programmes and through innovative robotic 
pipe sealing techniques. We are piloting the use of parts of our gas 
network for the distribution of hydrogen and RNG. We are working with 
suppliers to evaluate potential alternatives to SF6.

Energy efficiency is one of our key focus areas. We have ongoing energy 
reduction targets in our US and UK core office facilities. As an example 
of our progress, in the UK, we have exceeded our target by reducing 
energy consumption by 11% from a 2015/16 baseline. In the US, we 
performed whole-building LED replacements at two of our key locations 
and expect to yield annual site electricity savings of 6% and 17%. We are 
also working to reduce our transport energy use through the purchase 
of alternative fuel fleet vehicles and employee programmes promoting 
the purchase/lease of electric vehicles.

For the US and UK, our operational energy use is 2,330 GWh, our 
facilities energy use is 285 GWh, our transport energy use is 405 GWh 
and electricity energy losses from our networks are 12,311 GWh. US 
generation is also responsible for 12,892 GWh. In these figures, facilities 
energy use is defined as the energy used in powering and heating our 
offices, whilst operational energy accounts for energy used in fulfilling 
our primary business. Transport covers business travel, including our 
own fleet, hire cars and personal car use for business. 

Understanding National Grid’s greenhouse gas emissions
We monitor and report our greenhouse gas emissions in accordance with 
the World Resources Institute and World Business Council on Sustainable 
Development Greenhouse Gas Protocol.

Scope 1: Direct Emissions from the operational activities of National Grid.

Scope 2: Indirect Emissions from gas and electricity purchased and used  
by National Grid. 

Scope 3: Other Indirect Emissions from activities occurring from 
sources that National Grid does not own or control.

Our main sources of greenhouse gas emissions  
are shown below. 

Key:

included in our net zero target

Greenhouse gas emissions

We have committed to achieving net zero 
emissions for our Scope 1 and 2 emissions 
by 2050. Most of our Scope 3 emissions are 
emitted from two key business activities: 
the sale of gas and electricity to customers 
in the US (82%) and the purchase of goods 
and services (18%). We are working with 
our customers and our supply chain to 
reduce Scope 3 emissions and assessing 
appropriate targets for our Scope 3 
emissions to align with pathways to 
2050 targets.

Our colleagues
We employ around 23,000 people, located both in the UK and the US. 
Our people are the lifeblood of National Grid. Their safety and wellbeing 
are our primary concern and a priority for every one of us at National Grid 
– they underpin everything we do. Any safety incident is one too many 
and we continually strive to improve safety for our employees. Our 
ambition is to ensure that all of our employees and contractors are able 
to go home safely at the end of each and every day.

Our COVID-19 response started with supporting our people to work 
safely from home or as required in the field for essential activity, and to 
support their physical and mental health needs wherever they are. We 
have also facilitated volunteering opportunities during the crisis, and 
increased paid-time available for volunteerism. 

Preparing our colleagues for the clean energy transition
Responsibility towards our people also means training them and 
(re)skilling them for the evolving needs of our businesses. The necessary 
skills and profiles of our employees and those at our partners and 
competitors are changing. We need forward-thinking, creative minds 
to help meet the challenges we face in connecting people to the energy 
they use. We anticipate a number of areas of increased focus in the 
future, such as data analytics to manage more complex grid flows and 
the customer interactions needed to balance supply and demand. We 
will also need skills to design and implement new energy technologies, 
such as renewables and heat pumps. Technicians will have skills to 
install and maintain energy efficiency measures and technologies as 
well as skills to support the deployment and enablement of new 
heating technologies such as hydrogen and change management skills 
to bring society along in the green transition. In 2019 National Grid 
commissioned a “Net Zero Skills Report” to identify the jobs needed 
to help society achieve net zero and provide a basis for engagement 
with stakeholders working on the challenge alongside us. 

Investing in our colleagues
Our people and our communities will benefit from the time and financial 
investments we are making in ensuring that the future skills needed for 
National Grid, and the broader energy industry, are available. We are 
developing national and local skills development partnerships and 
initiatives, with a focus on the lower-income communities we serve. 
We aim to give access to 45,000 young people from these communities 
over the next five years, tracking their progress from first interaction right 
through to employment at National Grid, our partners and suppliers, 
or adjacent companies and industries. Our employees are expected 
to play a critical role in these programmes.

Keeping our colleagues safe
The safety of all our employees, contractors and the general public is 
of prime importance to us. We measure the safety of our employees 
and contractors and this is reflected in our KPIs, shown on page 20. 
To ensure we maintain our high standards of safety performance, we 
have effective policies, procedures and training in place so we can 
continue to perform at the level we and our stakeholders expect. 

Delivering energy every second of every day is critical to the functioning 
of the economies and communities we serve. The reliability of our energy 
networks is one of the highest priorities after safety. Our networks 
continue to provide reliability running at more than 99.9% availability 
in both the UK and US. You can read more about this on page 19, 
and find out how we manage our operational risks on pages 22 – 25. 

Engaging with our colleagues
Through a third-party partner, we carry out an annual EES to measure 
engagement levels and to help us address areas employees believe we 
need to improve. Employee engagement forms one of our KPIs – you 
can read more about this and our performance on page 20. 

“We create an environment 
in which our employees can 
make a positive contribution, 
develop their careers and 
reach their full potential.”

Living wage
In the UK, we are accredited by the Living Wage Foundation. Our 
commitment to our direct employees extends to our contractors and 
the work they do on behalf of National Grid. We believe that everyone 
should be appropriately rewarded for their time and effort. We also go 
above the Living Wage requirements and voluntarily pay our trainees 
the Living Wage. 

We undertake a Living Wage review each year to ensure continued 
alignment. We also increase individual salaries as required.

Our culture
The culture we strive for stems from embracing our values: every day we 
do the right thing, find a better way and make it happen. You can read 
more about our values on page 12. We also know that building sufficient 
capability and leadership capacity (including effective succession planning) 
is an important factor in delivering our vision and strategy. You can read 
more about how we are mitigating the risks in this area on pages 22 – 25.

Health and wellbeing 
We take a proactive, risk-based approach to managing health and 
wellbeing at National Grid. We continue to focus our efforts on creating 
sustainable wellbeing behaviour change within our workforce. We do 
this mainly through education and training and by managing our key 
wellbeing risks. 

Our wellbeing programme focuses on musculoskeletal injury prevention 
and mitigation, chronic disease prevention, support for a healthy lifestyle 
and mental wellbeing. We engaged in mental health awareness week 
focusing on tools to support managers and employees dealing with 
mental health and wellbeing. The training has been well attended. 
We supported World Mental Health Day to focus on suicide prevention 
and encouraging employees to talk and help remove stigma. In 2019, 
the UK and NGV businesses signed up to the Mental Health at Work 
Commitment focusing on six key commitments which are implemented 
and monitored through the Thriving at Work standard. In the US, we are 
tackling musculoskeletal and soft tissue injuries through preventive 
athletic training programmes to encourage stretching and flexing 
before undertaking manual tasks. In 2019, the US launched a Fatigue 
Risk Management System, with essential training for employees and 
supervisors to identify and mitigate fatigue risk in each area of Operations.

Gender pay gap
We review gender and ethnicity pay gaps annually in both the UK and  
US and although we are broadly comfortable with our performance, 
we continue to strive to recruit and develop more women and ethnic 
minorities. For more information about our UK gender pay, visit our

Promoting an inclusive and diverse workforce 
National Grid is dedicated to building a workforce which is representative 
of the communities we serve, in all aspects of diversity. We also continue 
to provide an inclusive culture across each stage of our colleague journey. 

Our inclusion and diversity policies demonstrate our commitment to 
providing an inclusive, equal and fair working environment by: 
•  driving inclusion and promoting equal opportunities for all; 
•  ensuring our workforce, whether part-time, full-time or temporary, 

is treated fairly and with respect; 

•  eliminating discrimination; and 
•  ensuring that selection for employment, promotion, training, 

development, benefit and reward is based on merit and in line 
with relevant legislation. 

We are committed to transparency and reporting annually on our progress 
on BAME and female representation on our Board, at manager level, 
among new joiners and our workforce as a whole. We remain focused 
on bringing the best diverse talent into our organisation and supporting 
them to reach their full potential.

We also adopt this approach to our future talent, with our Apprenticeship 
and Graduate programmes actively encouraging applications from diverse 
candidates. During 2019/20, in the US we attracted 31% female applicants 
and 51% ethnically and racially diverse applicants to our graduate 
development roles. We also took 36% female applicants and 52% 
ethnically and racially diverse applicants into our internship programmes. 
Our UK Graduate Programme attracted 25% female applicants and 57% 
ethnically and racially diverse applicants. Our UK Industrial Placement 
and Student Internship programmes attracted 28% female applicants 
and 45% ethnically and racially diverse applicants. 

A total of 18.3% of our workforce have declared themselves to be 
of ‘minority’ racial or ethnic heritage and we currently have 24.7% 
females across our total workforce. We are very much aware, however, 
of the number of ‘declined to state’ responses we have across all diverse 
characteristics and as a result in 2019/20 we launched our #thisisme 
campaign, not only to increase our disclosure rates, but also to demonstrate 
our commitment to a culture of openness and security for colleagues to 
share who they are. This year also saw a number of our most senior leaders 
participate in reverse mentoring. This allowed them to get a different 
perspective on life, not only at National Grid but also more generally. 
This has provided a mutual knowledge share and dialogue between 
senior individuals from our organisation and more junior individuals from 
a diverse range of background with fantastic feedback from all parties.

We continually work to ensure our application, assessment, 
development and training provisions more broadly, are all inclusive 
and accessible. We offer our current colleagues training and 
development programmes which ensure they are aware of acting 
on bias, while providing specific development programmes for our 
diverse colleagues in both the UK and US. We have 17 Employee 
Resource Groups (ERG) (11 in the US; 6 in the UK), which are all 
highly active and visible across the business, with events and 
awareness-raising campaigns throughout the year (including a 
strong presence at WorldPride in New York this year). Our ERGs 
also provide a crucial support network to our diverse colleagues. 

We continue to participate in numerous awards and benchmarks 
to recognise the great work of our colleagues (including Disability 
Confident, The Times Top 50 Employers for Women, Best Places 
to Work for LGBT Equality and Forbes 2019 Best in State Employer; 
we were also shortlisted in the Top 10 Outstanding Employers at The 
Ethnicity Awards for 2019). These also offer us the opportunity to learn, 
focus our strategy and continually improve our approach to inclusion 
and diversity. We have close partnerships with external best practice 
organisations and are active members of sector- and industry-wide 
groups which ensure we are sharing best practice and campaigning 
at a sector-wide level for greater inclusion for all.

Our policy is that people with disabilities should be given fair 
consideration for all vacancies against the requirements for the role. 
Where possible, we make reasonable adjustments in job design and 
provide appropriate training for existing employees who become 
disabled. We are committed to equal opportunity in recruitment, 
promotion and career development for all employees, including those 
with disabilities. Our policy recognises the right for all people to work 
in an environment that is free from discrimination. 

The gender demographic table that follows shows the breakdown in 
numbers of employees by gender at different levels of the organisation. 
We have included information relating to subsidiary directors, as this is 
required by the Companies Act 2006 (Strategic Report and Directors’ 
Reports) Regulations 2013. 

We define ‘senior management’ as those managers who are at the 
same level, or one level below, the Executive Committee. Our definition 
also includes those who are directors of subsidiaries, or who have 
responsibility for planning, directing or controlling the activities of the 
Group, or a strategically significant part of the Group, and are employees 
of the Group.

“We are fair to our suppliers 
and committed to paying 
them promptly.”

We are fair to our suppliers and committed to paying them promptly. 
We also influence our supply chain to operate as responsible businesses, 
requiring all suppliers to share our commitment to respecting, protecting 
and promoting human rights.

This includes alignment to the United Nations Compact Guiding 
Principles, the International Labour Organisation standards and the 
Ethical Trade Initiative Base Code as a reference standard.

The economy 
Our economic contribution to society comes primarily through the 
delivery of safe and reliable energy. Crucially, we make sure energy 
reaches homes and businesses safely, reliably and efficiently. But our 
contribution as a responsible, purpose-led business also comes as an 
employer, a tax contributor, a business partner, and community partner.

We help national and regional governments formulate and deliver their 
energy policies and commitments. Our approach to regulatory 
consultation is to seek a framework that puts consumers at the centre 
of our price control, while enabling the clean energy transition. Evolving 
that partnership to help enable the clean energy transition and slow the 
pace of climate change before it cannot be reversed, will also be key in 
protecting future economic growth, and safety and wellbeing in society.

Our geographic footprint means that our economic contribution is felt 
in lower-income communities that can truly benefit from the ripple effect 
of our local presence, from rural communities in New England, to the UK 
where most of our economic contributions are made outside London. 
Our tax contribution helps to fund services and we are committed to a 
coherent and transparent tax policy and recognise our economic role 
in society in doing this (more information on tax can be found on 
pages 28 – 37).

National Grid plc Annual Report and Accounts 2019/20

Strategic Report | Our commitment to being a responsible business

Governance 
Our approach to corporate governance plays an important role in 
helping us develop our culture at National Grid – a culture that embraces 
diversity and inclusion, and an environment where everyone can fulfil 
their potential. Our Board will continue to play a vital role in setting the 
tone right from the top. We apply a robust framework to ensure that 
stakeholder considerations are suitably captured and enhancements 
made to strengthen the views of stakeholders in the boardroom.

Human rights 
Respect for human rights is incorporated into our employment practices 
and our values, which are integral to our Code of Ethical Business 
Conduct – the way in which we conduct ourselves allows us to build 
trust with the people we work with. We earn this trust by doing things 
in the right way, building our reputation as an ethical company that our 
stakeholders want to do business with, and that our employees want to 
work for. We were recently recognised by Ethisphere as one of 2020’s 
World’s Most Ethical Companies. Although we do not have specific 
policies relating to human rights, slavery or human trafficking, our Global 
Supplier Code of Conduct (GSCoC) integrates human rights into the way 
we do business. Throughout our supply chain alongside other areas of 
sustainability we create value, preserve natural resources and respect 
the interests of the communities we serve and from which we procure 
goods and services. Through our GSCoC, we expect our suppliers to 
comply with all legislation relating to their business, as well as adhering 
to the principles of the United Nations Global Compact, the International 
Labour Organisation (ILO) minimum standards, the Ethical Trading 
Initiative (ETI) Base Code, the UK Modern Slavery Act 2015, the US 
Trafficking and Violence Protection Act 2000 and, for our UK suppliers, 
the requirements of the Living Wage Foundation. 

Anti-bribery and corruption 
We have policies and governance in place that set and monitor our 
approach to preventing financial crimes, fraud, bribery and corruption, 
including our Code of Ethical Business Conduct (covering bribery and 
corruption). We have a Company-wide framework of controls designed 
to prevent and detect bribery. 

We investigate all allegations of ethical misconduct thoroughly and, 
where appropriate, we take corrective action and share learnings. We 
also record trends and metrics relating to such allegations – only a small 
percentage of these relate to bribery or corrupt practices, so we do not 
consider them to be material for reporting purposes. 

Governance and oversight 
We review and update our framework regularly so we can make sure our 
procedures remain proportionate to the principal risks we have identified. 

Our UK and US Ethics and Compliance Committees (ECC) oversee the 
Code of Ethical Business Conduct and associated awareness programmes. 
Any cases alleging bribery are required to be referred immediately to the 
relevant ECC so the members can satisfy themselves that cases are 
investigated promptly and, where appropriate, acted upon, including 
ensuring any lessons learnt are communicated across the business. 

The Audit Committee receives an annual report on the procedures currently 
in place to prevent and detect fraud and bribery. You can read more about 
the Audit Committee’s role on pages 76 – 81. None of our investigations 
over the last 12 months have identified cases of bribery. 

Anti-financial crimes policy 
We have launched a new Anti-Financial Crimes policy which applies 
to all employees and those working on our behalf. It sets out our 
zero-tolerance approach to bribery, fraud, money laundering, tax 
evasion and other corrupt business practices. 

To ensure compliance with the UK Bribery Act 2010 and other relevant 
legislation, we operate an anti-financial crime risk assessment process 
across the Company to identify higher-risk areas and make sure 
adequate procedures are in place to address them. Fraud and bribery 
risk assessments are conducted annually across the business. As part 
of our global training strategy, we introduced an e-learning course for 
all employees so they can adequately understand the Company’s 
zero-tolerance approach to fraud, bribery or corruption of any kind. 

“Our Code of Ethical 
Business Conduct sets 
out the standards and 
behaviours we expect from 
all employees to meet our 
values of Do the Right 
Thing, Find a Better Way 
and Make it Happen.”

Ethical business conduct 
Our Code of Ethical Business Conduct sets out the standards and 
behaviours we expect from all employees to meet our values of Do the 
Right Thing, Find a Better Way and Make it Happen. The document is 
issued to all employees and is supported by a global communication 
and training programme to promote a strong ethical culture. Additionally, 
we provide briefings for high-risk areas of the business, such as 
Procurement. Our Code is updated every three years and is currently 
being updated with a release date later in 2020. In addition, we have 
a new Ethics Business Management Standard which provides a 
framework around our ethics programme and describes what is 
expected of the business. 

Compliance framework 
Each of our business areas is required to consider its specific risks and 
maintain a compliance framework, setting out the controls it has in place 
to detect and prevent bribery. As part of our compliance procedure, the 
business is asked to self-assess the effectiveness of its controls and 
provide evidence that supports its compliance. 

Each year, all function heads are asked to certify the compliance in 
their area, and to provide details of any exceptions. This culminates 
in presentation of a Certificate of Assurance from the Chief Executive 
to the Board (following consideration by the Audit Committee). 

Working with our supply chain 
Our GSCoC is issued to our suppliers annually and sets out our 
expectations and fundamental principles, including preventing and 
detecting bribery and corruption, which should extend into the supply 
chain. All our suppliers must comply with all laws relating to their 
business which includes human rights, business ethics, resilience, 
supplier diversity, skills development and environmental sustainability, 
as well as adherence to the principles of the United Nations Global 
Compact, in accordance with all applicable local, state, federal, national 
and international laws or regulations including the UK Bribery Act 2010 
and the US Foreign Corrupt Practices Act 1977. We provide specific 
guidance and briefings for high-risk areas, so contractors, agents and 
others who are acting on behalf of National Grid do not engage in any 
illegal or improper conduct. 

Whistleblowing 
We have confidential external speak-up helplines available 24/7 in all the 
regions where we operate. We publicise the contact information to our 
employees and on our external website so concerns can be reported 
anonymously. Our policies make it clear that we will support and protect 
whistleblowers and any form of retaliation will not be tolerated.

Our commitment to being  
a responsible business continued

Preventing modern slavery 
We strive to prevent modern slavery from taking place anywhere in our 
business or in our supply chain. 

We also facilitated an industry masterclass to discuss common issues 
in the sector and work more closely together to increase awareness and 
drive positive change.

We expect all our suppliers to be compliant with the Modern Slavery Act 
and to publish a Statement if required. Each year, we update our own 
Statement and publish this on our Company website in line with the 
Modern Slavery Act’s requirements. In 2019, our Statement was 
independently assessed by Development International, a new ranking 
of the nation’s largest publicly listed organisations, and we were listed 
in the top quartile for FTSE 100 listed companies. In 2018, we were also 
assessed by the Business & Human Rights Resource Centre (BHRRC) 
and were positioned 12th in the FTSE 100 ranking and recognised as one 
of a ‘small cluster of leaders standing out’ in this space. BHRRC did not 
publish a ranking in 2019.

We are an active member of the United Nations Global Compact 
Modern Slavery Working Group, signatories to the Construction 
Protocol, and are working with Achilles to develop a community 
approach to address the issue. We are also revising our procurement 
process, so that modern slavery criteria and identifying human rights 
risks form part of our sourcing process. 

In 2019 we signed up to the People Matter Charter which has been 
created by the Supply Chain Sustainability School, of which we are 
a partner member, to develop and implement consistent workforce 
standards throughout our industry.

We work closely with our suppliers and peers to build on our knowledge 
and promote best practice in the industry to combat modern slavery. 
During 2019, we continued to engage with suppliers identified as being 
within potentially high-risk categories. Through this engagement, which 
included a US workshop following on from the UK workshop in 2018, 
we encouraged our suppliers to conduct similar risk assessments with 
their own supply chain.

Non-financial information
This section provides information as required by regulation in relation to:
•  environmental matters; 
•  our employees; 
•  social matters; 
•  human rights; and 
•  anti-corruption and anti-bribery. 

In addition, other information describing the business relationships, 
products and services which are likely to cause adverse impacts in 
relation to the matters above, can be found as follows: 
•  business model – pages 2 – 7; 
•  KPIs – pages 18 – 20; 
•  principal risks – pages 22 – 25; and
•  Audit Committee Report (our due diligence) – pages 76 – 81.

Our policies and related governance
Descriptions of the policies and the outcomes pursued in relation 
to the above matters are discussed, where material, throughout 
this section. A full list of our policies can be found online, at  
www.nationalgrid.com/about-us/corporate-governance

In addition to our policies, we have a suite of Business Management 
System (BMS) standards. These standards provide the foundation for 
bringing energy to life for our stakeholders. They act as our guiderails 
by defining the minimum requirements for the high value and risk 
activities most important to our business – allowing our leaders to 
effectively drive change instead of responding to it.

The BMS delivers benefit in four key ways:
Risk Mitigation: The BMS defines and sets minimum requirements 
for our principal and other risks so they can be effectively and 
consistently managed across our businesses.

Best Practice: The BMS establishes a common language and 
framework for what constitutes best practice and provides the 
opportunity for Communities of Practice (CoP) to share across 
the organisation. 

Standardisation: The BMS helps us build efficient processes and 
lean functions in our business areas with global responsibilities – HR, 
IT, Procurement, Finance and Corporate Affairs. By building one way 
of doing things, we can capture the maximum benefit from our work.

Simplification: The BMS acts as a catalyst to challenge and remove 
documentation and rules that don’t deliver value. The standards will 
also increase the freedom of leaders to act, knowing the boundaries 
which can’t be compromised as they strive to work in new and 
innovative ways. 

Some of the BMS standards that we pursue to ensure consistent 
governance on a range of non-financial matters, can be seen below. 
They are not limited to this selection. These have been summarised 
for the purpose of the Non-Financial Information Statement.

Financial Disclosures (TCFD) 

National Grid has committed to 
implementing the recommendations 
of the TCFD in full, and below is our third 
disclosure which builds on our previous two. 

Key Milestones in 2019/20

This year we have continued to make good progress on the 
recommendations, aided by developments in the markets we operate 
in, with aggressive ‘net zero emissions’ and renewable targets set in 
the UK, New York State, Rhode Island and Massachusetts in the last 
12 months, as well as increasing public scrutiny and focus across the 
sector and in corporate boardrooms. This year, we have progressed our 
scenario planning work, elevated climate change as a principal risk to 
our Group risk register, issued our first green bond, and evolved our 
greenhouse gas emission reduction targets. Our work was recognised 
by CDP as we were named on its climate change A List for the fourth 
year in a row. 

In our 2018/19 disclosure, we outlined the areas we planned to focus our 
attention on during 2019/20. The table below outlines those actions, the 
progress we have made against each during this financial year, and our 
areas of focus for the upcoming financial year.

Actions to progress in 2020/21

Governance

Ensuring senior leadership has an 
appropriate understanding and responsibility 
for the risks and opportunities associated 
with climate change.

Continue to increase knowledge and 
skills among senior leadership in this 
area and include climate change expertise 
as a factor to consider in our Board 
succession planning.

The Board and Executive Committee have 
discussed climate change throughout the 
year and taken actions as follows:
•  engaged with key stakeholders on aspects 

of the net zero transition, for example, 
bringing in the UK Committee for Climate 
Change to speak to Electricity Transmission 
executives; 

•  senior leadership devoted a day to 

responsible business and our total societal 
impact, including climate change; and
•  committed National Grid to reduce our 
Scope 1 and 2 emissions to net zero 
by 2050.

Strategy

The use of climate-related scenarios to inform 
our business strategy (and disclosure of the 
possible outcomes under those scenarios).

We have undertaken an analysis of the impact 
to our business model of transitional scenarios 
where decarbonisation goals are, or are not, met. 
The details of this are presented in the scenarios 
section of this disclosure. 

Assess the physical risk to our assets using 
updated climate scenarios and quantify the 
potential impacts. Incorporate this work into 
the transition scenario analysis. Build on the 
transitional scenarios we have developed.

Risk 
Management

Embedding climate change into our risk 
management process. 

Metrics  
and Targets

The development of metrics and targets 
to assess performance, and influence 
decision-making and remuneration.

After a full review of our risks, climate change 
is now a principal risk for the Group, from its 
previous status as an emerging risk. See 
page 23. We also developed ‘business unit 
specific risks’ to ensure that each part of the 
business has specific climate change risks.

Deliver identified control actions to mitigate 
climate change risk. Continue to review the 
risk and controls as further information is 
developed, including through scenario 
planning work.

We announced our commitment to be net zero 
for Scope 1 and 2 emissions by 2050 in 
November 2019. We revised our interim Scope 
1 and 2 targets to an 80% reduction by 2030 
and a 90% reduction by 2040.

Personal objectives will be set throughout 
the business to ensure delivery against our 
commitments. Continue monitoring our 
metrics and targets and develop and/or 
evolve metrics, as needed.

In addition, our NGESO published an update 
to their operability strategy showing the 
milestones to deliver zero carbon operation 
of the Great Britain Transmission network by 
2025. See page 39.

Financial Disclosures (TCFD) continued

How do we approach the governance of climate-related risks 
and opportunities? 
The Board of Directors is responsible for the oversight of climate-
related risks and opportunities impacting the Group. During the year, 
there has been an increased focus on climate-related matters as the 
landscape evolved with regulatory developments and changes in 
stakeholder expectations. The Board was involved in the following 
discussions relevant to climate change:
•  Approving the Group’s commitment to achieve net zero for our 
Scope 1 and 2 greenhouse gas emissions by 2050 replacing 
our previous target of 80% reduction by 2050. In addition, we 
have set the following interim targets: 80% reductions by 2030 
and 90% by 2040.

•  Climate change was elevated to a principal risk during the year, 
with the risk now being owned by Alison Kay, a member of the 
Executive Committee who has responsibility for Group Safety, 
Health and Environment. The governance process that was 
undertaken to upgrade the risk from an emerging risk to a 
principal risk is described in the case study on page 23.

•  Strategy sessions were held, which included discussions related to 
climate change and considered the scenario testing performed this 
year (discussed on page 26). Topics discussed included the clean 
energy transition, the future of heat, as well as our strategy for 
renewables and electrification of vehicles. In addition, the Board 
held four sessions to consider our role as a responsible business 
and our role as a key facilitator of the energy transition featured. 
•  Approving the RIIO-2 submissions which reflect our investment 

proposition for supporting the UK energy transition.

•  Quarterly review of performance on our environmental sustainability 

metrics and targets.

Responsibility for asset investment and maintenance planning is 
delegated by the Board to the Executive Committee who then further 
delegates the responsibility to the core operational businesses.

What is the oversight process for climate change related risks 
and opportunities?
The Safety, Environment and Health Committee (SEH Committee) 
is responsible for assessing the Group environmental sustainability 
strategy and performance, as well as how the Company adapts its 
business strategy considering potential climate change risks and 
opportunities. As part of this, the SEH Committee tracks, challenges 
and seeks assurance for the delivery of the plans approved by the 
Executive Committee.

The Audit Committee remains responsible for reviewing and approving 
the content of our TCFD disclosures and is taking an increasingly active 
role in overseeing disclosures around metrics and targets. The 
Committee considered papers in September 2019, November 2019, 
March 2020 and May 2020 summarising the financial reporting and 
disclosure considerations in respect of climate change. 

The Finance Committee is responsible for overseeing our financing 
strategy. This year, the Committee reviewed and approved our Green 
Financing Framework. This framework, published in November 2019, 
aims to facilitate the disclosure, transparency and integrity of our Green 
Financing for our stakeholders.

A TCFD steering group oversees progress against the TCFD 
recommendations and the publication of our annual disclosure. 
The group reports to the Chief Financial Officer, Andy Agg. 

Future Intent
As the climate change landscape is evolving, we will continue to build 
upon the good base level of experience and knowledge within senior 
management (including at Board and Executive levels), as well as 
consider climate change expertise in our Board succession planning. 
The SEH Committee will continue to monitor our environmental 
sustainability performance quarterly and approve updates to our 
environmental sustainability strategy and targets annually. The Audit 
Committee will continue to oversee the programme to evolve the 
assurance model for our responsible business reporting. The Finance 
Committee will consider the financial impact of environmental factors on 
our credit metrics and relevant considerations with regards to debt investors. 

What is our strategy for responding to climate change?
Our strategy focus is three-fold: tackle the climate crisis by helping the 
markets we operate in transition to a net zero economy, while reducing 
our own impact on the environment and ensuring our networks operate 
reliably under changing conditions. Our strategy is informed by the 
evolving climate change policy and ambitions of the states and countries 
in which we operate, by the risks and opportunities identified during our 
continuing climate change scenario testing and by our ambition to have 
a positive impact. 

Our financing strategy, which includes us issuing debt from our 
operating companies, is focused on aligning the debt issuances to 
the business purpose of each of our regulatory deals. As part of this 
strategy, we launched a Green Financing Framework to enable us to 
issue green bonds, loans or other financial instruments in November 
2019. Green bonds allow us to access new capital pools and engage 
with investors who are keen to work with asset owners to facilitate the 
clean energy transition. In January 2020, we issued our first green bond 
in the UK, with the €500 million proceeds being used to finance projects 
with an environmental benefit across our UK electricity business. We are 
currently evaluating issuing a green bond in the US in 2020.

Regulatory Framework
The next 10 years are a crucial period with expected rapid change in 
the energy system, and therefore it is vital that the funding and regulatory 
framework is in place to deliver against these targets. Across our business, 
we are developing proposals for our regulatory rate filings that support 
our strategy to enable the transition and reduce our own impact. 

UK RIIO-2 Business Plans
Our RIIO-2 Business Plans were developed through a comprehensive 
stakeholder engagement programme throughout the RIIO-2 process 
and have also evolved to reflect the UK government target, announced 
in June 2019, to achieve net zero emissions by 2050. Our plans cover a 
crucial period (2021 – 2026) for investment to help deliver the UK’s net 
zero target. The route to net zero emissions is not yet clear but our plans 
are flexible enough to deliver the investment needed in the 2020s. We 
have built a plan to align with the pathway to net zero by 2050.

In our Electricity Transmission business, we propose £1.35 billion of 
expenditure to connect new generation and transport electricity across 
the country to where it is consumed, connect us to neighbouring 
electricity markets and support the Electricity System Operator in being 
able to operate a zero-carbon electricity system by 2025. Whilst 
consistent with Ofgem’s business plan criteria, we recognise that these 
investments alone are insufficient to deliver net zero targets and have 
therefore proposed whole system options to accelerate progress 
towards net zero, for example through ultra-rapid vehicle charging at 
motorway service areas. As the optimal path to achieving net zero is 
unclear, we developed a series of uncertainty mechanisms that allow 
our plans to flex to deliver against the range of low-carbon system 
developments our customers could bring forward.

In our Gas Transmission business, we recognise that natural gas has an 
important role to play in supporting the transition to a low-carbon future. 
Natural gas, hydrogen and biomethane can help to decarbonise heat, 
the biggest source of UK carbon emissions. Our business plans cover 
a period where developing options and understanding choices is key. 
We will focus on leading the development of options associated with 
gas transmission, specifically hydrogen, to facilitate the decarbonisation 
of heat, industry and transport.

In our ESO business, our business plans focus on facilitating the 
transition to net zero. For example, our business plans aim to deliver new 
architecture and systems in our control centres to be able to operate a 
zero carbon network by 2025, and new monitoring and control systems 
to ensure power system stability in a low-carbon world.

Across all our businesses our plans include targets and commitments to 
manage our own environmental impact, with £530 million of investment 
planned across Electricity and Gas Transmission. We have committed to 
reducing NOx emissions from our gas compressors, and achieving net 
zero construction emissions by 2025/26. We are targeting investments 
to replace leaking SF6 (an insulating gas and source of GHG emissions) 
equipment to reduce emissions by 50% by 2030, phasing out the 
procurement of new assets containing SF6 and introducing SF6 free 
technologies.

In the UK, there is uncertainty on what further measures will be 
needed to adapt to climate change and meet the UK goal of net zero 
by 2050. We welcome Ofgem’s Decarbonisation Action Plan and the 
shift to a more flexible, adaptive regulatory price control regime with 
a system-wide net zero re-opening mechanism. 

US Rate Cases
In the US, we have ongoing and upcoming regulatory rate case 
proceedings. In all proceedings, gas and electric, we are focused on 
including proposals to support our climate change strategy and enable 
the net zero transition of the states in which we operate.

In the US gas distribution businesses, we are focused on decarbonising 
our gas networks and the heating sector. We are doing this by reducing 
emissions related to natural gas through energy efficiency and demand 
response, continued investment in our leaking pipe replacement 
programmes and advancement of the future of heat. For example, we 
included a $90 million future of heat proposal in our April 2019 KEDNY/
KEDLI filing which combined expanded energy efficiency and demand 
response programmes, renewable natural gas interconnection 
investments, geothermal investments, and a hydrogen blending study. 
We plan to include future of heat proposals and continued pipe 
replacement programmes in our next Niagara Mohawk and 
Massachusetts gas rate filings. This work aligns with the Rhode Island 
Heating Sector Transformation, launched by the Governor in July 2019 to 
identify how the heating sector needs to change to meet the state’s 
climate objectives. This initiative concluded in April 2020 with 
recommendations provided to the Governor. Those recommendations 
included increased energy efficiency, electrification through air and 
ground source heat pumps, and fuel decarbonisation through renewable 
natural gas and renewable oil.

In the US electric distribution businesses, we are focused on climate 
change and the new energy landscape. For our next Niagara Mohawk 
rate case filing, we will submit a proposal that focuses on three key areas: 
grid modernisation, customer engagement and supporting the state to 
achieve its clean energy goals outlined in the Climate Leadership and 
Community Protection Act (CLCPA). We will also leverage these grid 
modernisation investments to enable customers to engage with their 
energy consumption in an informed and seamless manner. Enabling 
New York State’s clean energy transition is a common theme across all 
the above-described proposals and will be further enabled by our work 
in the electrification of transportation. The Massachusetts rate filing, 
approved in October 2019, includes work to advance Massachusetts’s 
climate objectives including a climate change mitigation and adaptation 
plan, an off-peak rebate programme for electric vehicle owners, 
approval to include up to $50 million in energy storage in our 2021 grid 
modernisation plan filing, and a path forward for a significant investment 
in electric vehicle charging infrastructure in 2021. In Rhode Island, we 
launched an electric vehicle infrastructure and off-peak rebate 
programme and will be filing a Grid Modernisation and Advanced 
Metering Functionality proposal in the second half of 2020/21. 

Future Intent
We are in the process of updating our budgets and forecasts to reflect 
the detailed financial impacts of our net zero strategy. 

low-carbon solutions. We have assumed that transition impacts 
in this scenario would be focused around technological shifts to 
support decarbonisation.

•  In the 4ºC scenario, changes are less rapid and less comprehensive, 

and emissions remain high, so that the physical ramifications of 
climate change are more apparent by 2030. In rationalising this 
slower global progress, our 4ºC scenario assumed fragmented and 
ad hoc policy (within the Group’s operating territories and globally). 

The main transition impacts of the 1.5ºC scenario were:
•  A trend towards more large-scale renewables in the 
generation mix: this would be a positive development for 
the Group, but for our electric network businesses the rate 
of new connections could increase beyond today’s levels: 
this could increase costs or, without investment ahead of need,  
lead to a backlog. 

•  A trend towards electrification: increases in electricity demand 
would likely trigger electricity network upgrades and investment. 
Although network costs are a very small proportion of the customer 
bill, spikes in spending would need to be managed in conjunction 
with our regulators to ensure that customers, especially lower-income 
customers, are not unduly adversely affected.

•  Public pressure on gas: in line with the Committee on Climate 

Change and other external sources, we do not believe substitutes to 
methane gas for space heating can reach scale in our territories by 
2030 (or even 2040, unless extensive new policy is rapidly deployed). 
However, in this scenario we anticipate that, without mitigating action 
to reduce and offset emissions, there is a risk of pushback against 
the use of gas by environmental groups or concerned citizens. 
We are already experiencing growing resistance to building new gas 
infrastructure in our US business from politicians, concerned citizens 
and environmental groups.

The main impacts of the 4ºC scenario were:
•  Physical ramifications of climate change: in this scenario 
we expect extreme weather events of escalating severity and 
frequency, which could increase disruption to our assets and our 
customers. This would require investment to ‘harden’ assets and 
would heighten the safety risk to our field employees. Our approach 
to physical climate risk is discussed in more detail below.

•  Lower system visibility: as this scenario sees less coordinated 
policy and regulation in pursuit of decarbonisation, we would 
anticipate a greater variety of solutions being deployed across our 
networks. This could increase overall system costs and reduce 
visibility over the network, potentially slowing our responsiveness  
to disruptive events. We do note, however, that a greater number  
of distributed assets would increase the potential for local balancing, 
which could mitigate this.

•  Inequality of access: without carefully designed policy, we believe 
decarbonisation activities have the potential to leave some sectors of 
society behind: for example, heat pumps and the energy efficiency 
upgrades they typically require are currently cost-prohibitive for many. 
As well as the ethical implications of this, there is a risk to the Group, 
especially for our US businesses, that a proportion of our customers 
would struggle to pay their bills.

How have we advanced our climate change scenario analysis? 
This year, we have advanced our scenario analysis work that considered 
both the transition and physical risks to our business. This work is and 
will continue to inform our strategy and investment plans.

Analysis shows that, without action, both scenarios present risks to us. 
However, while these would need to be managed, we would not need 
to materially change our business model. We also note that for a group 
in our position, some of these changes represent material opportunities.

Transition Risk Analysis
To further understand the risk that climate change could have on our 
business, we have undertaken a high-level scenario analysis. We used 
two scenarios: the first assumes that the global response to the threat of 
climate change is enough to limit global average temperature increases 
to no more than 1.5ºC above pre-industrial levels (as set out in the Paris 
Agreement) by 2100 (the 1.5ºC scenario). The second scenario assumes 
that the 1.5ºC target is missed by some margin, comparable to a 4ºC 
global average temperature increase (the 4ºC scenario).

To facilitate business planning, we have considered scenarios out to 
2030. In this analysis, we assessed the impacts of the scenarios without 
factoring in activities we might take to adapt to the threats of climate 
change, or the opportunities of decarbonisation. 

We made the following simplifying assumptions: 
•  In the 1.5ºC scenario, rapid changes are made to progress 

decarbonisation goals: coordinated policy, regulation and customer 
behaviour favours bans on polluting technologies, and support for 

Physical Risk Scenario Analysis
We recognise that, due to the amount of carbon already in the atmosphere, 
some escalation of extreme weather events is likely in both the ‘1.5ºC’ 
and ‘4ºC’ scenarios, especially under a longer-term view. This year, we 
began Group-level work to assess our physical risks to ensure that any 
necessary measures to defend our assets are identified. We ran an initial 
workshop with the US, UK and NGV teams and the UK Meteorological 
Office (Met Office) consultancy team to define the key areas of focus 
(e.g. flooding, icing and hurricane frequency for the US and UK regions) 
and define how the climate science can answer the questions we have 
on the weather conditions our assets will have to operate in up until 
2100. Using the output of this work, we will develop and progress a 
scope to analyse weather data specific to the regions we operate in and 
assist in developing an understanding of the vulnerability of our assets 
as well as the mitigating measures that will be needed to protect them. 
We are also undertaking work with a team from the Massachusetts 
Institute of Technology (MIT) to study the impacts of weather changes 
related to climate change in the northeastern US.

What are the risks and opportunities from climate change? 
The rapid changes in the energy market and demands to meet net zero emission targets present several challenges that are both a risk and 
opportunity for us. In addition, the changes in temperature and weather patterns have and continue to present challenges and risks. These risks 
and opportunities, along with a summary of the work we are doing to address them, are presented in the table below.

Markets 

Markets

The operating environment and regulatory 
framework are rapidly changing in line 
with the decarbonisation of the electricity 
and gas networks in the UK and US. 

Commercial opportunities from the 
transition towards net zero (short/medium 
and long-term). 

Facilitating the transition to a low-carbon economy is central to our purpose as a business, 
and certain key actions we are taking in relation to decarbonisation and decentralisation are 
set out on pages 12 – 15.

Development of a strategy to enable the building of charging stations across our 
US jurisdictions and UK highways and to meet demand for electric vehicles.

We have developed a dedicated programme to understand what is required to incorporate 
hydrogen and renewable natural gas into the gas supply.

Acquisition of Geronimo, a leading developer of wind and solar generation assets based 
in Minneapolis, Minnesota, to help position us to develop and grow a large-scale 
renewable business in the US.

Our interconnectors form an important part of the UK decarbonisation, by allowing us 
to exchange surplus renewable electricity with neighbouring countries. 

We are leading the development of Carbon Capture Utilisation and Storage (CCUS) 
technology in the Humber, UK, to support this area to become the first zero carbon region 
in the world.

Our continuing energy-efficiency programmes across Massachusetts, Rhode Island 
and New York have reduced CO2 emissions by more than 725,000 metric tonnes over the 
past year which is equivalent to the GHG emissions from over 156,000 passenger vehicles 
driven for one year.

Markets

Changes in supply and demand for 
existing and new technologies.

Our analysis, underpinned by the ESO Future Energy Scenarios (FES) shows that, even with 
increased decentralisation of electricity, there is a key role for Electricity Transmission in the 
UK under a range of scenarios that meet the UK’s 2050 climate change goals.

As the transition to renewable generation continues, we will work with the Long Island 
Power Authority (LIPA) to transform our generation fleet by responding to future RFPs. 
Under our existing contracts which extend through 2028, LIPA determines their reliability 
and sustainability needs and which units are operated, retired or transformed.

Our FES will be aligned to not meeting, meeting or exceeding the 2050 net zero target.

Security and 
reliability

Electricity grid reliability and 
peak capacity.

Our principal focus is around ensuring that our electricity network is able to actively support 
and contribute to a future where demand for and supply of electricity are ever changing. 

Security and 
reliability

Facilitating zero carbon operation 
of the Great Britain electricity system.

With growth in renewables increasing intermittency on the network, and electrification of 
transport and heat likely, we are working with our stakeholders to ensure that grid reliability 
is understood, managed and planned at appropriate levels. 

In April 2019, the ESO announced its ambition to transform the operation of the electricity 
system by 2025. Our goal is to be able to operate the system safely and securely at zero 
carbon whenever there is sufficient renewable generation online and available to meet the 
total national load. 

To facilitate this, the ESO has agreed contracts with five parties, worth £328 million over 
a six-year period, in a world-first approach to managing the stability of the electricity system. 

Physical risks

Extreme weather 

Physical impacts from extreme weather 
events such as storms and flooding.

We continue to address the physical risks from extreme weather-related events, with a focus 
on flooding events (in both the UK and US) and storm hardening (in the US). See case study 
on page 61. As this work continues, it will be informed by not only the weather patterns we 
are experiencing, but also the results of the ongoing scenario testing.

Changing weather 
conditions

Increased frequency of weather incidents 
leading to asset damage/compromise and 
operational risks.

We will undertake a review of resilience from weather impacts to date. Work is ongoing 
to update standards with updated information. As an example, our US engineering team 
is updating standards for new and rebuilt substations to address changes in inland and 
coastal flooding projections.

The ongoing scenario testing will consider whether our design standards are still 
appropriate under different scenarios, for example, a wider temperature range.

Changing weather 
conditions

Changes in supply of and demand for 
gas and electricity as a result of changing 
weather conditions.

The ESO is undertaking a project, Mapping Impacts and Visualisation of Risks of extreme 
weather on system operation (MIVOR), to evaluate the impacts of extreme weather events 
on system operation up to 2050.

Future intent 
We will continue our physical risk analysis in 2020/21, including a review 
of the effectiveness of adaptation measures to date, identification of future 
areas of vulnerability, and assessment of these against future weather 
conditions and the likelihood of that happening. We will complete the 
scenario testing and determine any further adaptation measures that 
need to be undertaken. While financial provision has been made in the 
UK business plans for flood measures based on 2019 climate science 
data, additional adaptation measures can only be determined after this 
exercise has been completed and will be considered under the 
uncertainty mechanism provisions in the RIIO-2 business plans. The US 
business plans also include actions to harden our networks against 
expected weather conditions in the nearer term, but this work will help 
us better plan for future conditions.

What is the process for identifying and managing  
climate-related risks? 
Our approach to identifying and managing the risks in our business 
is set out on page 22. During the year, a Group-level bespoke climate 
change principal risk was developed and added to our Group risk 
register, as described in the case study on page 23. The newly added 
climate change principal risk is underpinned by a series of Group 
controls and actions to mitigate the risk (this is further described on 
page 24). Several of the Group-level controls have been implemented 
while others are in progress. Ongoing work includes establishing 
programmes to develop the skills in our current and future workforce. 
Our recent report, Building the Net Zero Energy Workforce, looks at the 
skills and expertise the energy sector will need to help the UK reach its 
emissions target. It also identifies the need to recruit for 400,000 jobs 
in the sector between 2020 and 2050 to meet the target. Supported 
by the #jobthatcantwait campaign, we will be recruiting new talent 
who can help deliver the transition to net zero and adapt our networks 
accordingly. We have seen a marked increase in applicants in response 
to this campaign. 

Following the adoption of the Group-level climate change principal risk, 
the US and UK businesses developed bespoke climate change risks 
on their respective risk profiles. These risks are being cascaded to the 
underlying operating business units to develop to ensure their risks 
and control actions are specific to them. 

Future intent 
The Executive Committee will review the results as part of the regular 
semi-annual review of Group risks in early 2020/21 and as part of that 
discussion will specifically consider whether changes need to be made 
to the Group climate change risk.

Case study: extreme weather-related planning
Ensuring network reliability is core to our business and we 
are constantly undertaking actions, often referred to as storm 
hardening, to improve our networks’ resilience to the increasing 
frequency of strong weather events, given the significant impact 
this can have on our customers. These activities have focused 
on both our electric and gas businesses. As noted in the financial 
review (see page 30), this year we incurred $98 million of major 
storm costs, the majority of which are recoverable under our rate 
plans. Examples of ongoing efforts in 2020/21 include hardening 
efforts for our gas assets in Long Island and New York City. 
We worked with a collaboration of New York State and New 
York City representatives and other key stakeholders, to develop 
recommendations for future storm hardening and resiliency 
projects for our gas network, strategies for addressing climate 
risk factors, and guidelines for incorporating climate change 
projections in long-term capital planning. Another example is 
our annual investment in our electric distribution infrastructure 
to improve resilience and grid modernisation work to increase 
speed in knowing outage locations and improving our ability to 
restore supply.

In the UK, flood defence has been a keen focus for the business. 
Our target is resilience to 1 in 1000-year flooding events in the 
UK or a 0.1% chance in any given year. This resilience level was 
developed through consultation with Ofgem and BEIS via the ENA 
Flood Working Group and recognised in the National Flood 
Resilience Review 2016 as being best practice for critical local 
and national infrastructure. As of 31 March 2020, we had invested 
£71 million in flood defences with work completed or in progress 
at 37 sites and expected to be completed at a further 12 sites in 
2020 and 2021. Our RIIO-2 (2021 – 2026) plans aim to protect 
a further 100 sites from surface-level flooding and recommend 
further investments to manage the risks posed from the secondary 
impacts of flooding, such as erosion and subsidence to our tower 
and cable routes.

Financial Disclosures (TCFD) continued

Case study: the future of heat
The transition to a low-carbon economy is and will continue to change 
the sources of energy used (e.g. heat pumps and hybrid solutions), 
and the way energy is supplied and consumed (e.g. building retrofits 
to improve energy efficiency). Gas distribution in the US and gas 
transmission in the UK and US remain core to our business strategy, 
and we believe it will remain central to the energy mix in both 
countries. There is likely to be a mosaic of solutions, including 
reducing emissions from the natural gas transmission and distribution 
networks, as well as conversions to both electric and lower carbon 
gas heating (renewable natural gas or gas blended with hydrogen), 
focusing on cost-effective solutions and meeting different 
consumer needs. 

In conjunction with government agencies, other utilities and key 
stakeholders and other gas networks, we have developed a programme 
of work to gather evidence and help us understand what is required 
to incorporate hydrogen and renewable natural gas into the gas 
supply. We are also working with industry to consider what 
improvements and changes are needed to maintain well-functioning, 
liquid gas markets throughout the transition, and ensure security of supply 
and delivery of natural gas, renewable natural gas and hydrogen.

Refer to page 13 for further details on the future of heat.

Future intent 
We continually review our metrics and targets, as needed, to ensure 
that the data we are measuring is meaningful, aligns with our strategy, 
and is providing the information the business and our stakeholders need 
to effectively monitor our performance and demonstrate our progress. 
In 2020/21, we will be laying out our pathway to achieve our net zero by 
2050 emission reductions and setting targets to align our ambitions and 
provide better visibility to our progress.

We are also evaluating development of a meaningful Scope 3 target that 
enables us to align to Science Based Targets Initiative (SBTI) criteria, 
specifically focusing on our customers.

What metrics are used to assess these risks and opportunities? 
We have continued to advance our environmental sustainability 
strategy, focusing on three key areas: climate change, responsible 
use of natural resources and caring for the natural environment. 
We have metrics and targets that allow us to measure our impact 
on the environment, demonstrate our commitment and monitor our 
performance. As previously discussed, the cornerstone of our suite 
of metrics is our commitment to reducing our impact by achieving 
net zero for our Scope 1 and 2 emissions by 2050, with interim targets 
of an 80% reduction by 2030 and a 90% reduction by 2040. Numerous 
underlying metrics support this goal and our broader sustainability 
ambition, including reducing the carbon footprint of our operating 
facilities, enhancing the natural value of our properties, recycling and/or 
reusing our recovered assets and reducing our office waste. These are 
discussed in more detail on pages 50 and 51.

We have also included enhanced disclosures in the financial statements 
prepared under IFRS to explain how we have considered the financial 
impacts of climate change, in particular evaluating the impact of new 
net zero commitments in our territories, and the effect this has had 
on judgements and estimates such as the useful economic life of 
our assets. See notes 1 and 13 to the financial statements for details. 
This remains a recurring area of focus for the Audit Committee.

Corporate Governance

Letter from the Chairman

During the year, our discussions around RIIO-2, 
gas supply contingency planning in the US, the 
brief power outage on 9 August 2019 in the UK 
and payment of the final dividend are examples 
of how the Board has had regard to section 
172 of the Companies Act 2006. We have 
considered the broader implications of our 
decisions, not just for shareholders but for a 
wider group of stakeholders and the likely 
consequences of our decisions in the longer 
term. On page 44 we set out our key 
stakeholders and how we have engaged with 
them to ensure that their views are being 
captured in the boardroom, to assist us in 
maintaining focus on creating the right culture 
for the Company. We continue to provide 
details throughout the Directors’ Report of the 
stakeholder matters that are considered in our 
decision-making. We will continue to engage 
with our stakeholders in a way that is guided by 
our purpose to Bring Energy to Life, our vision 
and values and the Company’s culture.

This year the Board has continued with its 
chosen approach to workforce engagement 
under the Code: to build on and enhance 
the extensive existing range of engagement 
activities and employee communication 
channels to properly consider workforce 
views in relevant decision-making processes; 
see page 73 for further information. Following 
the success of our employee engagement 
sessions with Non-executive Directors in 
2018/19, we have continued to utilise and 
evolve these sessions throughout the year to 
ensure key topics, discussions and potential 
areas of concern amongst the workforce are 
considered. The Board has been able to 
identify key trends and topical issues, such as 
gender pay, culture, and safety. Where trends 
have been identified and Board action taken, 
employees have been kept informed through 
internal communications. Our chosen approach 
allows for the sharing of responsibility, and 
interaction amongst all Board members, which 
we believe ultimately drives a greater focus on 
the ‘true employee voice’ in Board decisions. 
We will continue to review and adapt our 
approach to ensure that we are utilising this 
vital engagement both in and out of the 
boardroom including considering the facilitation 
of virtual engagement sessions to enable the 
Board to continue with this despite COVID-19 
restrictions. 

Culture and the internal Board evaluation
Promoting a culture of openness and debate in 
the boardroom is one of my key responsibilities 
as Chairman, and as a Board we play an 
important leadership role in promoting the 
desired culture throughout the organisation. 
The Company has spent considerable time 
over the last few years getting the culture right 
for the Company and it continues on its 
journey; you can read more about this on 
page 72 where we explain how culture formed 
part of this year’s Board evaluation. 

During the year, we undertook a formal and 
rigorous internal evaluation of our Board and 
Committees which included some follow-up 
areas from our external evaluation last year. 
The evaluation focused on three areas: Board 
effectiveness; Board decision-making; and 
organisational culture and the individual style 
of leaders. During the evaluation process the 
Board gained insight into the different aspects 
of culture and the alignment of cultures around 
the Company. A facilitated session was 
arranged to discuss the comparisons of the 

Board evaluation results with the culture survey 
results of the Company’s senior management. 
Unfortunately, due to the COVID-19 pandemic, 
this session has been postponed as it would 
not have been effective to do this when Board 
members were not physically in the same 
location. The evaluation process and associated 
outcomes can be found on page 74. 

Board succession and diversity
In November 2019 Dean Seavers, US 
Executive Director stepped down and in 
May 2019 and January 2020 we appointed 
Jonathan Silver and Liz Hewitt as Non-
executive Directors respectively. On 
appointment Jonathan joined the Finance 
Committee, Remuneration Committee and 
Nominations Committee and his US regulatory 
experience alongside his strong financial 
background has provided valuable insight 
into Board and Committee discussions. Liz 
became a member of the Audit Committee, 
Safety, Environment and Health (SEH) 
Committee and Nominations Committee on 
appointment. Liz’s diverse and extensive 
experience has served to strengthen the 
Code’s requirement in relation to the Audit 
Committee’s competence, as a whole, to be 
relevant to the sector in which the Company 
operates. Her input to Board and Committee 
discussions is already very helpful. The 
Nominations Committee oversaw the rigorous 
selection process for these appointments. 
See page 84 for more information. 

Last year Mark Williamson, the Board’s Senior 
Independent Director, reported that in order 
to lead the Company through the completion 
of the RIIO-2 regulatory process it would be 
in the Company’s best interests for me to stay 
beyond the nine-year term identified in the 
Code. Following on from this, in January 2020 
I formally notified my intention to step down 
as Chairman of the Board following the 
identification of a suitable successor. Mark has 
been leading this process and we plan to have 
my designated successor in place in time for 
me to step down at the 2021 Annual General 
Meeting (AGM) at the latest. I will be standing 
for re-election at the Company’s AGM in July 
2020 and, in order to facilitate an effective 
succession, it is intended I remain as Chairman 
until my successor has been successfully 
onboarded. This crucial succession process 
will be set out further in next year’s 
Nominations Committee Report. 

Ensuring a diverse culture on the Board is 
crucial to improving effectiveness, encouraging 
constructive debate, delivering superior 
performance and enhancing the success 
of the Company. With the recent appointment 
of Liz Hewitt I am pleased to report that we are 
again meeting our diversity target of 33.3% of 
the Board being women. We also currently 
meet the Parker Review target for ethnic 
diversity on FTSE 100 boards. You can read 
more on how we strive towards our objectives 
in our Board Diversity Policy on page 85.

Dear shareholders,
I am pleased to present to you our Corporate 
Governance Report for 2019/20. The report 
provides an insight into the activities of the 
Board and its Committees over the year 
including how it has evaluated its effectiveness 
and how it provides appropriate and effective 
stewardship to the Company to ensure it 
achieves its strategic priorities. It also discusses 
how we create value for shareholders and 
wider stakeholders during an ongoing period 
of external economic, regulatory and 
political uncertainty. 

Towards the end of the year we have seen 
the acceleration of the COVID-19 pandemic. 
This is having a profound effect on how 
companies around the world operate during 
these unprecedented times and we recognise 
the increased importance of good governance 
at a time when effective engagement and 
collaboration with our stakeholders has never 
been more important. As a Board we are 
closely monitoring the developments of 
COVID-19 and the impact of this on all areas 
of the Company. Please see overleaf for 
information on our response to COVID-19.

Over the year there have been a number 
of other key events such as the brief power 
outage experienced on 9 August 2019 in the 
UK and the gas connection supply challenges 
in downstate New York in the US. Other 
external factors which have influenced the 
Board agenda include: the regulatory 
environment in the UK and the RIIO-2 business 
plan submissions; the increased gas regulation 
in the US, in particular New England; the 
increased political uncertainty leading up to the 
December 2019 UK General Election; Brexit; 
and the impact of the legal separation of the 
ESO. All of which have had, and some will 
continue to have, an impact on the way we 
work and operate. 

UK Corporate Governance Code 2018 
and stakeholder engagement 
We are pleased to report that we are fully 
compliant with the requirements of the new 
UK Corporate Governance Code (the Code); 
see page 86 for information on how we have 
adapted our practices to ensure compliance 
and transparent reporting against the Code. 

Our stakeholders are very important to us and 
we remain committed to maintaining regular 
open dialogue and effective communication 
with them. With the global restrictions in place 
due to COVID-19 this is requiring us to consider 
alternative methods to ensure we maintain the 
same level of engagement.

Corporate Governance | Letter from the Chairman

Our response to COVID-19
In order for us, as a Board, to be able to effectively monitor the 
Company’s crisis management we met on a weekly basis throughout 
April 2020 to monitor the impact of the current COVID-19 pandemic on 
the Company’s operations and how the Company was responding to 
the latest developments. These meetings were moved to a fortnightly 
basis from May 2020 and we will assess the need and frequency of 
these regular briefings as the pandemic continues.

How we have considered our stakeholders during COVID-19
Our commitment to being a responsible business is central to the way 
in which we operate. This has been the governing principle behind our 
response to the COVID-19 pandemic as Directors. We have had to think 
through and debate on the choices and actions we need to consider 
over the coming months to position us best for success in the medium- 
to long-term taking account of the impact on our key stakeholders. The 
Board has continued to monitor its responsibilities to the Company’s 
different stakeholder groups. Good engagement has been crucial in 
understanding the views of our stakeholders in order to make informed 
decisions during this period of crisis. For example, the Company has 
been seeking feedback from employees that has helped to shape its 
response to the COVID-19 pandemic.

Our colleagues
Our colleagues have been critical in making sure that we keep the 
lights on. The Board considered both the physical and mental wellbeing 
of our employees and are regularly briefed on the actions that would be 
taken to keep them safe and also to equip them to work from home 
efficiently. The Board has been in support of these initiatives, including: 
sequestering critical operations staff on-site in the UK and US to ensure 
service continuity; senior leaders communicating regularly via virtual 
online group calls; webchats and video messages; rolling out mental 
health training courses; and understanding colleague sentiment to the 
crisis and the COVID-19 recovery strategy through a pulse survey in 
the UK and US. The Company has not implemented pay reductions, 
furlough or compulsory redundancy schemes. We continue to monitor 
progress of how the Company can accommodate employees to return 
safely in the field, and how we can build on some of the positive changes 
in our culture and ways of working as the restrictions are lifted.

Communities
Our employees have also been supporting our communities by 
volunteering and providing their time and expertise to support charities 
and the most vulnerable. In the UK for example, as well as monetary 
support to various charities, the Company is operating a food bank 
and has helped the University Hospitals Birmingham (UHB) Charity to 
purchase almost 400 tablet computers that will be used by patients to 
help them speak to their loved ones while in isolation, see page 15 for 
a case study. In the US, the Company approved cessation of service 
disconnections for non-payment of outstanding bills. This reflects our 
commitment to support the communities in which we operate. Looking 
beyond the short-term, the Board will be kept informed of work to 
support getting people back into employment and into crucial roles, 
as well as helping support small- and medium-sized businesses 
(SMEs) to drive the local economies we operate in.

Investors 
The Board recognises it is imperative to promote the success of the 
Company on behalf of its members. The Finance Committee has held 
two ad hoc meetings to consider the short- and longer-term liquidity 
of the Company in a range of different COVID-19 related scenarios. 
The Board approved the recommendation to pay a final dividend in 
August 2020 following stress testing of the financials in various 
adverse scenarios.

Customers, regulators and suppliers
We are very conscious that many of our customers are currently 
experiencing additional financial challenges and have therefore 
willingly agreed to moratoriums on debt collection activities in our 
US regulated businesses.

Furthermore, US Niagara Mohawk sought and received permissions 
from regulators to defer for three months, scheduled rate changes that 
would have increased customer bills as of 1 April 2020. In addition, we 
decided to postpone the filing of the US Niagara Mohawk rate case 
which could have resulted in bill increases in 2021.

The Board also supported the active and constructive engagement 
with Ofgem to protect customers by supporting the proposal for the 
relaxation of network charge payment terms for those suppliers and 
shippers who are facing cash flow challenges as a result of COVID-19. 
Additionally, the Board noted the request made to modify the collection 
of forecast additional balancing costs by the ESO for a further year. 
These costs, estimated at up to £500 million, are required to safely and 
securely manage and balance the system given the unprecedented 
reduction in demand levels caused by COVID-19. We recognise that 
the increase is significant and is a material issue for ESO customers. 
The Board notes that the ESO is working with Ofgem and the industry 
with a view to ensuring that any scheme put in place is in the interests 
of end consumers and our customers. We have also continued the 
development and tender of future work for our suppliers, giving longer 
term visibility and greater certainty of income and the Board has been 
kept informed of any impacts on our suppliers and supply chain. 

We will continue to work closely with our stakeholders across both sides 
of the Atlantic in the current environment. The Board continues to be 
kept updated regularly on our COVID-19 response and on learnings that 
can be sustained to improve our ways of working and Company culture.

For information on how we have considered our stakeholders through 
the year see pages 44 – 47.

Your Board remains committed to the highest standards 
of Corporate Governance and in 2019/20 continued to 
embed the new UK Corporate Governance Code into 
the work that we do.

Our Board is responsible collectively for the effective oversight of the 
Company and its businesses. It determines the Company’s strategic

setting and leading the Company’s culture and wider sustainability goals. 
It considers key stakeholders in its decision-making and, in doing so,

Strategy remained a key focus throughout the year. The Board 
participated in two interactive strategy sessions in addition to 
the time allocated during Board meetings this year. The offsite 
sessions in September 2019 and January 2020 provided the 
Board with an opportunity to scrutinise business performance 
against the strategic plan and review the key strategic objectives 
for the year. In the year, the Board focused on:
•  developing a Business Plan that meets the Group’s 

requirements, aligned to the Company’s purpose, vision and 
values and underpinned by a robust financial strategy; 

•  reviewing and scrutinising Group trading performance, budget 

and consideration of share price; 

•  shareholders’ interests if the Labour Party had won the 2019 

UK General Election and implemented its manifesto 
commitment to nationalise National Grid UK regulated business 
and interconnectors; 

•  growth strategies for NGV, including renewable generation 

strategy; 

•  performance updates from the UK and US businesses; 
•  the key milestones and progress made by the Company  

on the energy transition; 

•  climate change and our strategy to further reduce our 

emissions, to achieve net zero by 2050 and make a wider 
contribution to the decarbonisation of the economies in which 
we operate; 

•  innovation and technology – see separate section below;
•  the increasingly strong performance of the UK and US 

commercial property portfolio; and 

•  the sequence of events that took place on Friday 9 August 

2019 cumulatively resulted in a widespread electricity power 
outage across the country.

Employee 
engagement 
and culture

Discussed the ongoing financial strategy and business plan for 
the year. Regular updates were received on emerging themes 
and key external challenges, and particular consideration was 
given to these and the current political environment.

The Group’s financial capacity under the Business Plan was 
stress tested using the current approach to fund the dividend 
until Financial Year 2026, in the context of current market 
expectations. The Board also reviewed the suitability of the 
Group’s dividend policy wording considering the key regulatory 
processes in the UK and US. 

In light of the COVID-19 pandemic, the Board discussed the 
issues that had been considered and analysis undertaken in 
relation to the payment of a dividend, which had included 
financial scenarios and resilience testing, and consideration 
of stakeholders including investors such as pension funds.

This year the Board received biannual updates on the 
implementation of employee voice on Board activity and culture. 

The Board reviewed the existing employee engagement 
implementation plan and commented on the overview of activity 
for the next half of the year. Focus has continued on improving 
communication channels between the Board and employees 
to ensure feedback and updates on actions are shared. 

Discussed the importance of a diverse and engaged workforce 
to deliver our Group strategy and the continued need to ensure 
an open culture where dialogue between the Board, senior 
management and the workforce is encouraged.

Our workforce continued to be a key focus as we navigated the 
impact of the COVID-19 pandemic. The health and safety of our 
employees remained paramount and discussions centred on 
keeping critical employees safe whilst their work continued. 
The Board received weekly updates on employee wellbeing 
and absenteeism.

Our colleagues

•  Approval of the initial five-year plan and the 
viability and going concern statements;

•  Confirmation that the Group had a financially 

sustainable business model for the foreseeable 
future, defined for this purpose only as the five 
years from March 2019 to March 2024;

•  The Board considers a range of factors when 
annually reviewing and setting the dividend, 
including expected performance and regulatory 
developments. No dividend policy changes were 
recommended and the current policy was 
reaffirmed; and 

•  Approved the payment of the final dividend at its 

additional June 2020 Board meeting.

Our colleagues

•  Board input on the approach taken to workforce 
engagement activities and the topics discussed 
based on employee feedback; and

•  The Board believes that existing approaches and 
mechanisms enable comprehensive two-way 
engagement opportunities with the workforce and 
is satisfied that the approach taken is an effective 
alternative to the proposed methods set out in 
the Code.

Please see pages 72 and 73 for more information.

Political and 
regulatory 
environment

The Board has continued to focus on how to promote the 
success of the Company during further developments to the 
external environment in the UK and US. 

In the UK, regular updates were received on risks and 
opportunities posed by Brexit proposals and the potential for 
state ownership, and continued engagement activities with our 
stakeholders on the issue. 

In the US, the Board received regular updates on the gas supply 
constraint in downstate New York. Once an agreement has been 
reached with the Governor of New York, the focus for the US 
Business will be on executing the longer-term supply strategy and 
undertaking a major change in the way it engages with external 
stakeholders in New York. 

•  Board input on, support for and monitoring of 

the UK and US regulatory strategies;

•  Political sub-group of the Executive Committee 
continued to take a more hands-on approach to 
the evolving political and regulatory landscape 
and its implications for the Company; and
•  The Board agreed that a lessons learned 

exercise would be undertaken which would 
include an assessment of the Company 
stakeholder management at the US state political 
level. The reviews were conducted by external 
consultants. The Board received a comprehensive 
assessment of the lessons learned at the March 
2020 meeting and the action plan to implement 
the reviews’ recommendations was approved 
at the April 2020 meeting.

Matters considered

Key decisions made / link to purpose

The Board scrutinised and challenged the Company’s UK 
regulatory strategy throughout the year, providing feedback, 
guidance and support for its ongoing development. 

The Board reviewed the financials of the business plans, 
noting that the majority of spend was associated with asset 
health and increased cyber security requirements. 

A strong stakeholder engagement strategy was adopted 
by the Transmission and System Operator Boards. This 
commitment was demonstrated by signing engagement 
charters to be stakeholder led and to be part of the User 
Group process. Our final business plans were submitted to 
Ofgem in December 2019 following extensive stakeholder 
engagement panels, challenge groups, and consideration 
against the 2050 net zero target. 

•  Draft business plans were reviewed, and the 

Board approved the creation of a sub-committee 
of the Board, chaired by the Chairman, to 
confirm the content for the business plans and 
accompanying assurance statements prior to 
the final submission to Ofgem;

•  the sub-committee considered how the 

comments from the Finance Committee on the 
Financeability Assurance Statements had been 
taken into account; and

•  stakeholder engagement consisting of 2,800 
individuals, representing the full cross-section 
of our stakeholder segments, and 13,000+ 
consumers, shaped the plans to deliver a safe 
and reliable network while enabling the transition 
to a low carbon network. The Board reiterated 
that the plans had inbuilt mechanisms to cope 
with potential changes to the energy landscape 
without increasing consumer bills in real terms.

Corporate Governance overview continued

Our culture journey

We recognise that how we do things is as important as what we do. 

The Board is responsible for influencing and monitoring culture 
throughout the organisation to ensure we are emulating desired beliefs 
and behaviours both in and outside the boardroom, and identifying 
areas where culture is embedded strongly and areas where shifts in 
culture are required. Our culture determines how we behave, 

how we make decisions and our attitude towards risk aligned with the 
Group’s purpose, vision and values. 

The Board has spent considerable time reviewing and determining the 
right culture for the organisation and recognises that there is still work 
to be done; the journey so far is outlined below.

2016/17

2017/18

Culture-themed internal Board and Committee evaluation 
assessed how the Board set the ‘tone from the top’ and how 
effectively this was cascaded throughout the Company.

Re-established clear purpose, vision and values and 
agreed a common definition of culture as ‘Our values, beliefs 
and behaviours that characterise our Company and guide 
our practice.’ 

The Board agreed culture-specific actions and a culture 
scorecard to be reported to the Board at least annually.

Agreed areas for increased Board focus including visible 
leadership and agreed the approach to engaging most 
effectively with employees.

Approved format for culture scorecard to aid the Board 
in monitoring culture at Group level. 

2018/19

Annual employee survey results were considered, and areas 
of improvement augmented into the Board’s behaviours 
including local engagement sessions in the UK and US.

The 2018 Corporate Governance Code was considered in 
depth by the Board, and key stakeholders were mapped out 
and discussed. The Board discussed its chosen approach 
to workforce engagement and an implementation plan 
was agreed. 

A revised culture scorecard was considered against an overall 
status for each of the Company’s values, bringing together 
data from teams including safety, ethics, compliance, supply 
chain management and customers. The Company committed 
to review how to evolve its approach to monitoring and 
measuring culture, along with how it could align the activity 
taking place to have a greater combined impact and make 
change happen at a faster pace.

2019/20

Looking 
ahead

Board culture evaluation
During the year the Board considered culture throughout 
its decision-making and the internal Board evaluation 
incorporated a review of culture. For more information 
see page 74.

Board review of culture scorecard
A new set of vision and values was agreed for the Company 
and the Board agreed to evolve its approach to measuring 
and monitoring culture across the Company with the aim of 
having a simplified approach. This would be based on the 
Company’s externally benchmarked annual safety survey, 
external customer feedback and the modification of the 
Company’s annual engagement survey to align around a 
more useful cultural diagnostic.

Culture diagnostic work throughout the year showed that the 
current culture was highly consistent across the Company, 
promoting a common identity across the organisation; areas 
of focus and change were also identified as part of the 
exercise and these have been considered.

Over the next year the Board will focus on the following 
culture-related activities:
•  monitor the implementation of the Company’s purpose, 
vision and values and the link to the Company’s culture; 

•  review and monitor the culture actions of the internal 

Board evaluation to ensure that the ‘tone from the top’ 
is correct and the Board has a clear view of culture both 
at Board level and within the organisation;

•  facilitate a culture session with the Chief Human 

Resources Officer and the Board to consider the results 
of the 2019/20 Board evaluation; and

•  review and monitor the change in culture and ways of 

working in the Company during the COVID-19 pandemic.

Workforce engagement

Employee engagement sessions
In response to the Code we have implemented a range of Employee 
Voice on Board (EVOB) activities to ensure that there is appropriate 
meaningful engagement between the Board and our workforce. 
Activities seek to expose Board members to a broad cross section 
of employees and employee experiences across the Company and 
our locations. Using the employee input through the EVOB activity 
to feed Board decision-making is a core part of the Code and a 
discussion topic and action log has been maintained following each 
of the relevant activities. 

During the year, the Non-executive Directors (NEDs) held three 
employee voice engagement sessions, in Boston, New York and 
London. Unfortunately the session scheduled for March 2020 in 
California was cancelled due to COVID-19. The employee engagement 
sessions provided an opportunity for employees and all NEDs to 
discuss topical subjects, including how successful employees felt the 
Company had been in embedding its values, beliefs and behaviours 
throughout the organisation, and shared their views on the gender 
pay gap. The two-way conversations were strongly encouraged and 
provided a great opportunity for the Directors and employees to 
engage more widely in a more informal environment. The Board 
allocates time directly after the sessions to discuss key outcomes 
and takeaways. Communications this year have increased to ensure 
our employees are kept informed about what was being heard in 
these sessions as well as progress against the actions taken from 
the meetings. The Board continues to receive updates on the actions 
taken from these sessions.

Communication

Employee Voice engagement sessions with NEDs
April 2019, Boston, US
Employees took the opportunity to discuss our corporate culture. 
The Board were pleased with the unanimous agreement of how 
important our safety culture was across the Company and the open 
discussions on wide-ranging topics which followed. Discussions 
focused on the requirement to positively reinforce the desired culture 
across all areas of the business and to ensure that communication 
channels and transparency of actions increased. Topics of concern 
were raised around the limitations of the existing processes and 
systems and the Board noted these challenges as areas for 
improvement. 

September 2019, New York, US
These sessions focused on the ongoing communication strategy 
being implemented throughout the Company. Discussions centred 
on sharing information across jurisdictions and individual business 
areas to help ‘find a better way’ and to promote project successes 
and learn from any programme failures. The Board listened to 
concerns around technology and provided an update on the plan 
going forward. 

December 2019, London, UK
The Board praised the active engagement at these sessions with 
topics focused on corporate identity, culture, diversity and the gender 
pay gap. Conversations highlighted the need to increase ethnic and 
gender diversity in senior roles and the NEDs informed the attendees 
of the latest initiatives (see table below). Positive conversations 
around reducing the gender pay gap also took place, which started 
with understanding the reasoning behind the difficulty experienced 
in recruiting women for some specific roles within the business. The 
Board encouraged discussions on ideas for programmes aimed at 
encouraging and enabling women to return from maternity leave. 

Employee Resource Group (ERG) Non-executive 
Director Dinner 
November 2019, London, UK
In November, a dinner was held to provide the opportunity for 16 UK 
ERG Chairs and leads to hold informal discussion with NEDs on 
the importance and impact of the ERG they support and lead. NEDs 
were able to discuss and gain feedback on inclusion and diversity 
related engagement topics. Following the positive feedback received 
from this session we have planned an equivalent US dinner for 2020.

What have we heard?

What have we done?

During the employee engagement sessions, some of 
the areas that we heard about were:

•  more needs to be done to create ethnic and 
gender diversity within the Company and to 
ensure that senior roles are representative

•  appreciating cultural differences is valued by our ethnically diverse colleagues, so we have refreshed 

and simplified our Reverse Monitoring process to build on cultural awareness by ‘walking in our shoes’; 
and

•  a new category for Inclusion has been created for the Chairman’s Awards, which can be awarded to 
any individual or group that has contributed positively towards inclusion at National Grid. Examples 
include involvement in our employee resource groups and evidence of working towards our Group 
inclusion and diversity strategy.

•  more visible support of and advocacy for the 
employee resource groups by the Board and 
Executive Committee

•  the Executive Committee has joined the Board in supporting and advocating the work of the employee 
resource groups on a regular basis, including attendance at the twice-yearly Inclusion Forums. The full 
calendar of events has also been circulated.

•  communication and cascading issues combined 
with process and system changes have caused 
problems

•  a communications strategy has been developed to ensure stronger alignment between the Group 
narrative and local communications to create a clear line of sight from Group messages to regional 
entities.

•  improvements needed in two-way communications 
to ensure priorities and focus areas are aligned 
and that all departments are working towards the 
overarching National Grid goal

•  the UK business has implemented a comprehensive leadership communications programme which 
includes Q&A sessions, breakfast and lunches with Executive Directors and increased frequency of 
Town Halls to engage in conversations about the Company’s direction, priorities and to give the 
Directors more opportunities to listen to issues and ideas from across the business.

•  frustrations that there are no obvious changes 

•  the US business is developing a communications plan to address any employee concerns more 

following the annual employee engagement survey

effectively and to ensure updates are communicated and cascaded successfully.

•  conversations around gender pay and 

suggestions that more needs to be done to 
engage and enable women returning from 
maternity leave

•  in response to gender pay gap concerns and that women require encouragement from the Company 
to return from maternity leave, we have compiled a list of leading senior examples who flex their work 
pattern. They have been interviewed by our communications team and their ‘work story’ will feature in 
our internal email bulletin every six weeks.

•  concerns around technology and cyber threats

•  a key focus for 2020/21 is to implement our updated information technology strategy in response to 

concerns raised by employees throughout the Group.

Performance evaluation

2019/20 Internal Board evaluation
Following the external Board evaluation which was undertaken 
last year, this year, we undertook an internally facilitated Board 
and Committee evaluation. 

The evaluation focused on Board development and the purpose of this 
review was to gain: 
•  insights into how Directors viewed the culture of the Company; 
•  an understanding of what constituted effective decisions made 

during the year and why; and

•  a deeper understanding about our culture and how it aligned with 

the Company’s ambitions. 

Our internal evaluation process

The effectiveness of each of the Board Committees was taken into 
account in the evaluation. The results confirmed that there were minor 
areas for improvement in relation to Board effectiveness. 

The process of the evaluation and the areas identified for further 
development are noted below.

January

February/ 
March

 Board received the Board and 
Committee Effectiveness 
Surveys – including questions 
on the effectiveness of the 
Board and its decision-making 
during the year.

Board completed a tailored Russell Reynolds Survey on 
organisational culture diagnostic and how Board members 
perceived the culture in the Company.

Completed Myers-Briggs type indicators (if not known).

Results received from surveys. These were reviewed and analysed to create an aggregated 
report in relation to organisational culture.

Comments from the effectiveness survey were discussed in the individual Director performance evaluations.

Later in 
2020

Effectiveness action plans 
created and discussed with 
the Board and its Committees.

Facilitated session with Chief Human Resources Officer analysing 
results of the organisational culture survey, including a comparison 
of the findings of the same survey completed by the Company’s 
senior management.

Actions to enhance the Board’s effectiveness for 2020/21

The Board discussed the results of the evaluation in April 2020 and in May 2020 the following actions were agreed:

Action

Responsibility

More effective discussion and decision-making through streamlined 
and targeted papers to the Board and its Committees.

Chief Executive and Group General Counsel and Company Secretary

External perspectives to be brought forward to the Board to bolster 
management expertise including in the areas of cyber, climate change, 
customer and developments in energy policy and energy technology. 

Chief Executive and Group General Counsel and Company Secretary

Continue with and enhance the effectiveness of employee engagement 
sessions to ensure a clearer alignment between these sessions and 
discussions/decisions made by the Board and its Committees. 

Chief Executive, Group General Counsel and Company Secretary and 
Chief Human Resources Officer

Devote more time to the discussion of strategic priorities at 
Board meetings.

Progress against actions for the Board agreed in 2018/19 external evaluation

Action

Progress made

Invite our customers into the boardroom to understand 
and directly hear their perspectives.

Continue to invite external speakers to Board meetings/
dinners on topical issues.

The Chairs of both our RIIO-2 Transmission and ESO Stakeholder Panels met with the Board in 
May and July 2019 respectively. This brought a valuable insight into how our RIIO teams were 
focusing on the needs of our customers during the regulatory review. We will keep the current 
situation under review and aim to invite additional customer groups into the boardroom later 
this year.

The Governor of Massachusetts and a member of the Governor’s office met with the Board in 
March 2019. The Chair, CEO and incoming CEO of Ofgem met with the Board in November 2019. 
We had invited Pacific Gas and Electric to meet with the Board in March 2020; however, this has 
now been postponed due to COVID-19. We continue to monitor the topical issues and will keep 
under review prospective external attendees who could meet with the Board later in the year. 

Use market research agencies to bring the voice of the 
customer and other stakeholders into the boardroom.

This has been undertaken this year through regular reports from the businesses who use these 
agencies to inform their views. 

Facilitated session to be held to consider how to 
enhance the collective strengths of the Board in light of 
the individual strengths evidenced as part of the 
evaluation.

An all-inclusive facilitated session was due to take place in March 2020 in California which would 
have covered culture and the results of this year’s internal Board evaluation. Due to COVID-19 this 
has been postponed. 

Sponsor of each paper to consider why the Board is 
being asked to consider a particular paper. On strategic 
papers, the Chairman to ask the sponsor at the 
beginning of the meeting what they are hoping to 
achieve in the meeting.

We have continued to develop our Board and strategic papers with the assistance of a third party 
to ensure Board meeting effectiveness. The amendments to our paper templates have been 
made to encourage and guide the sponsor and the paper author to consider the end aim or 
action they require from the Board. A focus for this year is to ensure the strategic aim is 
re-communicated at the beginning of each item before Board discussion and input commences. 

Add a Corporate Social Responsibility session annually 
to the Board agenda.

A deep dive into Corporate Social Responsibility took place at the January 2020 Board strategy 
session and will be discussed again later in the year.

Directors’ induction and training
Directors’ induction programme
Following appointment to the National Grid Board, each new Director 
receives a comprehensive induction programme tailored to their 
experience, background and the requirements of the role. Consideration 
is also given to Committee appointments, and the Group General 
Counsel and Company Secretary assists the Chairman in designing and 
facilitating the individual programmes. They are primarily designed with 
the purpose of onboarding and familiarising the new Directors with our 
business, vision, values, governance and people. 

Both Earl Shipp and Jonathan Silver were provided with a formal, tailored 
induction programme upon joining the Board last year. A detailed 
summary can be found below. 

The Board has also welcomed Liz Hewitt this year and we will report 
on progress against her induction plan next year. 

Non-executive Director induction examples
Earl and Jonathan both underwent a tailored induction programme 
covering a range of areas of the business including governance, 
remuneration and stakeholder matters. Throughout the year they have 
both met with senior management from key business areas and functions 
as well as employees across the UK, US and NGV businesses. They 
also both separately received a briefing from our legal advisors which 
included: company law and directors’ duties; corporate governance; 
the Market Abuse Regulation; and listing and disclosure obligations. 

Both directors met key employees in our Reward team to understand 
our reward strategy, remuneration policy and current market practice 
necessary to assist with their appointment to the Remuneration Committee. 

Earl Shipp
Focus was given to matters pertinent to his role on the Safety, 
Environment and Health Committee. 
•  Earl met with a number of employees throughout the business 

and in key safety roles including Paul Golby, the Committee Chair, 
to discuss National Grid’s Safety Framework, including carbon 
reduction and climate change, wellbeing, sustainability and our 
2050 net zero ambition. 

•  He undertook numerous site visits in both the UK and the US and 
attended a thorough and engaging safety roadshow in May 2019. 
This included a visit to our gas, electric and customer business units 
in New York and New Jersey where he was provided with a detailed 
end-to-end view of our smart grid approach and our Grid 
Modernisation Strategy. He also visited control rooms and contact 

centres in Boston and learnt more about our approach to 
personalisation and tailoring our customer experience journeys 
towards the electrification of vehicles and the clean energy future. 

Jonathan Silver
Focus for Jonathan’s induction was given to matters pertinent to his role 
on the Finance Committee. 
•  Jonathan met with the Group Treasurer and the Group Head of Tax 
who provided a summary of the financing strategy and an overview 
of the current financial risks faced by the Group, including the 
current risk appetite and management framework in relation to those 
risks. Discussions also included: treasury controls; processes and 
systems; National Grid’s tax strategy; the impact of US tax reform; 
and an overview of pension schemes and pension strategy. He also 
met key employees throughout the business to discuss financial 
accounting and control issues, the statutory audit, the annual 
business planning process and other substantive topics involving 
pensions and insurance. 

•  Jonathan undertook a number of site visits across Rhode Island and 
Massachusetts. This included a tour of a liquefied natural gas facility, 
as well as visits to renewable energy projects across Rhode Island. 
He also received in-depth information briefings and undertook 
control centre tours across the customer, gas distribution and gas 
transmission functions. 

Director development and training
The Chairman has overall responsibility for ensuring that our 
Non-executive Directors receive suitable ongoing training to enable them 
to remain an effective Board member. Individual training requirements 
are reviewed and agreed annually on a one-on-one basis. As our internal 
and external business environment continues to change, it is important 
to ensure that Directors’ skills and knowledge are refreshed and updated 
regularly. In addition to individual tailored training, updates on corporate 
governance, legal and regulatory matters are also provided by way of 
briefing papers and presentations at Board meetings. Non-executive 
Directors receive details of training and development opportunities 
offered by external advisors on various topics including cyber security, 
operational resilience, climate change and technical updates on a 
regular basis and we encourage and monitor attendance. In light of 
COVID-19, training opportunities have continued virtually via webinars. 
Additionally, the Non-executive Directors are expected to visit at least 
one operational site annually, a target which is regularly exceeded. 
Examples of site visits undertaken this year include a visit to the Feeder 
9 Project at Goxhill in the UK and South Street Substation Project in 
Providence, Rhode Island in the US.

Corporate Governance

Audit Committee

Continued focus on internal control over 
financial reporting and IT 
The Committee considers these matters at 
each meeting as a matter of routine. The focus 
in the early part of the year was on monitoring 
progress reported by management to address 
IT control deficiencies highlighted in previous 
years, and in May 2020 we concluded that 
sufficient additional control activity had been 
implemented to allow us to judge the 
‘significant deficiency’ previously reported in 
respect of US IT infrastructure controls to be 
remediated and closed. 

During the second half of the year, time was 
spent understanding management’s progress 
on enhancing control environments across all 
locations. In particular, in March and May 2020, 
the Committee considered management 
updates on the lessons learnt from the initial 
implementation of SAP S/4 HANA (as part of 
the MyFinance programme) for the ESO prior 
to the planned deployment of the technology 
as the financial system of record across the UK 
regulated business in mid-2021.

As we do annually, we considered the impact 
of these matters on the year-end attestation 
relating to the effectiveness of internal controls 
over financial reporting required under SOX. 

Overall framework for risk assurance
During the year, we discussed the Company’s 
control framework and its maturity and it was 
agreed that management would come back 
to the Committee regularly with updates on a 
number of improvements and enhancements 
to the Company’s risk, control and assurance 
framework that was consistent across the 
Group. I was pleased to see the appointment 
of a new Chief Risk and Compliance Officer 
and the establishment of a central team to 
drive a more common approach to second line 
of assurance. In May 2020, we were updated 
on the number of actions that had already 
been executed and the plans that had been 
developed, including the appointment of 
respective leads in all businesses and functions 
and the creation of implementation plans to 
push the improvements forward.

Cyber security and cyber audit update 
In September 2019, the Group Chief 
Information and Digital Officer and Chief 
Information and Security Officer joined for 
the delivery of the cyber-risk-related audit 
update to the Committee. The Committee 
noted the significant work being undertaken 
to remediate control weaknesses and that it 
was proceeding in line with expectations. 
Following this meeting, an update on digital 
was presented to the Board in December 2019 
to provide a consistent view of risk within the 
Company’s security framework. The Board 
confirmed it was comfortable with the 
Company’s current cyber priorities and 
stressed the importance of engagement 
with regulators for future cyber upgrades. 
The Committee will consider cyber assurance 
again later in the year. 

Review of the year 
The Committee met four times during the year 
to undertake its role in providing oversight and 
monitoring the integrity of financial reporting, 
the effectiveness of internal risk management, 
control and assurance processes, the 
Company’s governance framework and the 
external audit. Following the decision to defer 
the Group’s results announcement by a month 
in light of the COVID-19 pandemic, the 
Committee met in May 2020 with an additional 
meeting convened in June 2020. 

A substantial proportion of the Committee’s 
time from late March 2020 onwards was 
devoted to focusing on the year-end financial 
reporting, internal controls and related impacts 
arising from the COVID-19 pandemic in the UK 
and US. 

Assessing and responding to the impact 
of COVID-19 on year-end financial 
reporting and internal controls 
The Committee met as scheduled on 
25 March, in the week following the stay at 
home notices being issued in both the UK and 
US. The Committee discussed management’s 
evolving risk assessment relating to the impact 
of the pandemic on the year-end reporting and 
close process, as well as contingency plans. 
The Committee sought regular updates from 
management throughout the year-end close 
process as continuity plans were implemented.

As discussed on page 78, the key accounting, 
financial reporting and internal control related 
matters were discussed in the May 2020 
and June 2020 meetings, and throughout 
this period I remained in close contact with 
the Chief Financial Officer, receiving regular 
updates as the situation evolved. I am 
pleased to report that the Group’s close 
processes and Sarbanes-Oxley Act 2002 
(SOX) controls operated as intended without 
significant deviation. 

In light of the rapidly changing regulatory 
and economic circumstances throughout 
late March and early April 2020, a decision 
was taken to defer the Company’s results 
announcement by one month to June 2020. 
This decision was consistent with those taken 
by many other companies, and in keeping with 
advice from the Financial Reporting Council 
(FRC), Financial Conduct Authority (FCA) and 
SEC to afford management and the Board 
more time to better understand the evolving 
situation. This has also allowed us to 
appropriately address the key disclosure 
requirements in this Annual Report, in a 
number of key areas including: 
•  accounting matters – and in particular the 
impact of the moratoriums on collections 
in the US on bad debt reserves and cash 
collection forecasts; 

•  going concern – focused on the 

appropriateness of the Group’s analysis as 
regards reasonable downside scenarios; 
•  long-term viability statement – concerning 
the key assumptions and reassessment of 
viability from additional perspectives given 
the uncertainty and dynamic external 
factors and their cumulative effect in the 
medium and long term; and

•  the consideration and assessment of 
a specific COVID-19 risk scenario or 
cluster scenario.

S

Statement of compliance with the Competition and 
Markets Authority (CMA) Order – the Company 
confirms that it has complied with The Statutory Audit 
Services for Large Companies Market Investigation 
(Mandatory Use of Competitive Tender Processes 
and Audit Committee Responsibilities) Order 2014 
(Article 7.1), including with respect to the Audit 
Committee’s responsibilities for agreeing the audit 
scope and fees and authorising non-audit services.

Looking forward
Impact of COVID-19 
The Committee expects a significant 
proportion of its time will remain focused 
on the impact of the pandemic for the 
foreseeable future – across accounting, 
financial reporting and internal control related 
matters. The Committee will continue to 
monitor developments and adapt its approach 
to best support the Group’s stakeholders. 

Other matters
Cyber and internal control matters will remain 
high-priority areas as the Company seeks to 
embed improvements and efficiencies over 
the coming months. 

In addition, the Committee will continue to 
take a close interest in the Company’s evolving 
ESG-related reporting activities. It will also 
continue to monitor UK regulatory developments 
carefully, as the UK government responds to 
the findings of the Kingman and Brydon 
reports later in 2020.

Audit Committee Chair transition
Liz Hewitt was appointed as Non-executive 
Director and joined the Audit Committee as 
a member in January 2020. During 2019, 
Liz was identified as the right candidate to 
take over from me as Audit Committee Chair. 
Over the course of 2020/21 I will be working 
closely with the Nominations Committee and 
Board, as well as Liz, to ensure there is a 
seamless transition plan in place. As part 
of Liz’s tailored induction she has had meetings 
with myself, Deloitte, the Global Head of Audit 
and other senior members of the Company’s 
finance team and she will continue to work 
alongside me this year to ensure a smooth 
transition. 

Mark Williamson
Committee Chair

Climate change related financial 
disclosures
The Company has continued to make good 
progress towards providing disclosures 
consistent with the recommendations set 
out by the Task Force on Climate-related 
Financial Disclosures (TCFD). In the year, the 
Committee was presented with a roadmap 
to progress towards full compliance of TCFD 
and the current gap analysis. The Committee 
noted progress made in the year, including 
the identification of a principal risk relating 
to the threats and opportunities around 
climate change and the Company’s first set 
of disclosures concerning longer-term 
scenario analysis. 

In the context of the financial statements, 
the Committee also considered the impact 
of climate change on management’s key 
judgements and estimates, in particular 
regarding gas asset lives as set out on 
page 78. 

New UK system of financial record 
(MyFinance) – Phase 1
MyFinance became the financial system of 
record for the ESO at the point of legal 
separation on 1 April 2019. 

The Committee received updates from 
management on a regular basis throughout the 
year, in anticipation of the planned technology 
roll out across the UK business in early 
2021/22 (Phase 2). 

The Committee discussed the programme 
leadership, governance and assurance model, 
and lessons learnt from Phase 1 that will be 
applicable to Phase 2. 

Governance and regulatory changes
During the year, we received a detailed report 
on the outcomes and recommendations of 
the audit reforms in the UK following the 
publication of Sir Donald Brydon’s review into 
the quality and effectiveness of audit in the UK, 
as well as those of the UK Competition and 
Markets Authority and the Kingman review 
concerning the UK regulatory landscape. 
We also received a number of updates from 
Internal Audit in relation to the new Chartered 
Institute of Internal Auditors (IIA) Code of 
Practice and later in the year we will review 
this and make the appropriate changes to the 
Internal Audit Charter and the Committee’s 
Terms of Reference. 

Finance leadership changes 
The Committee also met privately with the 
Chief Financial Officer towards the end of his 
first full year in the role, to discuss succession 
planning within the Finance function during 
the coming year. We will continue these 
conversations in 2020/21.

Audit Committee continued

Significant issues/judgements relating to the financial statements
In considering the financial results announcements and the financial 
results contained in the Annual Report and Accounts, the Committee 
reviewed the significant issues and judgements made by management 
in determining those results. 

The significant issues and judgements considered for the year ending 
31 March 2020 are set out in the following table. 

In addition, the Committee and the external auditor discussed the 
significant issues addressed by the Committee during the year. You 
can read more in the Independent Auditor’s Report on pages 110 – 120. 

Matter considered

Factors and reasons considered, including financial outcomes

COVID-19 related 
matters

•  The Committee considered the accounting, reporting and internal control implications of the COVID-19 pandemic extensively 

throughout the period from late March through to June 2020. 

•  The Committee satisfied itself that management had adequately identified and considered all potentially significant accounting 
and disclosure matters in May 2020. Particular attention was devoted to understanding the implications of the moratoriums on 
collections of customer receivables issued by regulators in New York, Massachusetts and Rhode Island in March 2020. These 
events significantly impacted the business with immediate effect and contributed to a total bad debt charge of £234 million for 
the year, of which £117 million ($150 million) was considered incremental and due to the moratoriums.

•  The Committee also noted the other significant matters identified by management, being the additional uncertainty relating to 
determining the fair value of unquoted assets held by the Company’s pension and other post-employment benefit schemes. 
The Committee accepted management’s approach to delay finalising the financial statements until early June 2020 to allow 
for additional asset valuation data to be received and appropriate adjustments reflected over residual elements of specific 
asset classes. 

•  Concerning internal control, in March 2020, the Committee discussed management’s evolving risk assessment and contingency 
planning activities. The Committee noted, amongst other things, management’s process to have a back-up individual identified 
in order to plan for an unforeseen absence by someone involved in a key part of the year-end, close and reporting process. 
The Committee received regular updates throughout the year-end and close process, and acknowledged that in the vast majority 
of cases, control-related activities took place on time and by the individual originally assigned. 

•  In May and June 2020, the Committee was kept informed of the impacts of COVID-19 on the Company, including accounting 

matters, going concern and viability considerations, in light of continuing business developments as well as regulatory 
pronouncements, including from the UK FRC on the rapidly evolving corporate reporting landscape.

•  Details of the Committee’s conclusions in relation to going concern and the long-term viability statement are set out on page 80. 

Application of the 
Group’s Exceptional 
Items Framework

•  The Committee considered papers from management over the course of the year setting out how the exceptional items 

framework has been applied to certain events and transactions over the period, as set out in note 5 to the financial statements. 
•  For each item, the Committee has considered the judgements made by management, considering both, each item in isolation, 

and the aggregate view of the impact on adjusted profit and adjusted earnings per share. 

•  The Committee reached the conclusion that additional US environmental provisions, the impact of a 0.5% reduction in the 

discount rate applied to the Group’s environmental provisions and the reversal of the change in the UK tax rate should all be 
treated as exceptional.

•  The Committee concluded in line with management’s view that it was not appropriate to treat the incremental $150 million bad 

debt charge as an exceptional item this year. In addition, having considered the quantum and nature of the settlement in relation 
to the downstate New York gas moratorium and the additional COVID-19 related costs, it was deemed appropriate to include the 
impact of these items within adjusted profit. 

Gas Transmission and 
Gas Distribution asset 
lives in the context of 
climate change

•  Consideration was given to whether the developments in the UK and US towards binding carbon reduction targets should trigger 

any changes to our estimates, judgements or disclosures, especially regarding our gas asset lives. The Committee received 
various papers from management setting out an overview of the legislative changes in the period, analysis of the future pathways 
for the energy transition in the UK and US, and evaluation of the possible future use for our networks in these circumstances. 
•  The Committee accepted management’s view that on balance we believe there will be a role for our gas networks post 2050 

under a range of possible scenarios, and there is nothing at present to suggest that the asset lives should be shortened at this 
point. The Committee also accepted management’s view that in light of the evolving legislative developments and increasing 
investor attention, disclosure of a key judgement in relation to the impact of changes of legislation, disclosure of our gas asset lives 
as a key estimate, and appropriate sensitivity analysis were appropriate as set out in note 13 to this year’s financial statements. 

Going Concern 

•  The Committee evaluated papers prepared by management in May and June 2020, setting out management’s analysis under 
a reasonable but severe ‘worst-case’ scenario, principally reflecting potential outcomes as regards the length and severity of 
lockdown conditions, US customer moratoriums and a significant level of employee absenteeism. The Committee evaluated 
management’s analysis of the mitigating actions available to it to manage through such a situation, including the degree to which 
plans already existed and the likely challenges associated with implementing them. 

•  The Committee considered the assumptions made by management regarding availability of debt financing, noting recent debt 
issuances but also contingency plans in the event that debt markets could close. Having considered the available evidence, 
the Committee considered that the analysis presented, in conjunction with the disclosures included in note 1 to the financial 
statements, was appropriate to the Company’s circumstances.

Matter considered

Factors and reasons considered, including financial outcomes

Financial reporting

•  On an ongoing basis the Committee considered current IFRS financial reporting issues. In addition to the matters highlighted 

above assessed against the Group Exceptional Items Framework, we also considered the accounting as regards to the 
acquisition of Geronimo in accordance with IFRS 3 ‘Business Combinations’, the position at Western Link as regards to liquidated 
damage claims, and the impact of the 9 August 2019 UK power outage. 

•  Monitored and reviewed the integrity of the Group’s financial information and other formal documents relating to its financial 

performance, including the appropriateness of accounting policies, going concern and viability. 

•  Recommended to the Board the key accounting judgements and key sources of estimation uncertainty related to pensions and 
environmental provisions, made by management for the 2019/20 half and full-year financial statements, going concern and other 
reports filed with the SEC containing financial information. 

Internal controls

•  The Committee received regular updates on progress towards the Company’s annual SOX attestation. 
•  In March 2020, the Committee considered management’s progress against its wider financial controls action plan, and further 

process improvements introduced ahead of the year-end, including relating to governance process and formalisation of 
documentation around non-IFRS performance measures. 

Risk and viability 
statement

•  In addition to its regular work monitoring internal control processes, and reviewing and challenging the draft viability statement, 
the Committee specifically focused its attention this year on how the Company had factored the COVID-19 pandemic into its 
annual risk assessment process and long-term viability testing. 

External auditor

•  Received an update report at each meeting, including updates on the status of, and results from the annual audit process. 
•  Considered the external auditor’s report on the 2019/20 half and full-year results. 
•  Received and reviewed the management recommendations letter.
•  Ongoing consideration of the external audit plan, including monitoring the approach, scope and risk assessments contained therein.
•  Assessment of the effectiveness and independence of Deloitte, as well as review and update to the Group’s policy on the 

provision of non-audit services from Deloitte following updated FRC guidance in the year.

•  Review and approval of all audit fees proposed by management and for non-audit services in the year.
•  Recommended to the Board the re-appointment of Deloitte at the upcoming AGM. 
•  Received an update from Deloitte on workflows in relation to COVID-19 and received confirmation that the external audit team 

had been working well in new circumstances. 

•  Discussed the results of the client survey assessment, noting results were broadly consistent with the prior year. Key themes 

were highlighted and it was ensured that any actions would be incorporated into the 2020 audit. 

•  Continued to hold private meetings with Deloitte and maintained dialogue throughout the year.

Corporate audit

•  The Committee received a review of the Corporate Audit Charter. Minor changes were made to reflect the SOX control testing 

transition and the Committee approved the updated Corporate Audit Charter. 

Compliance, 
governance and 
disclosure matters

•  Received an update on the 2019/20 audit plan and the significant findings, and reviewed the plan for 2020/21. 
•  Received an update on cyber assurance and updates to the IT Risk Framework.
•  Reviewed PwC’s key messages in the external quality assessment (EQA) of Corporate Audit, noting the improvements made 

since the last EQA. 

•  Updated the Committee on the new IIA Code of Practice and confirmed a recommendation would be brought back to the 

Committee later in the year, which would also be reflected in the Corporate Audit Charter and the Committee’s terms of reference.

•  Welcomed Liz Hewitt to her first Audit Committee meeting in March 2020. 
•  Reviewed and approved the updated terms of reference for the Committee.
•  Received a detailed report on the outcomes and recommendations of the Brydon Review and other UK regulatory changes. 
•  Considered the progress towards implementing the Financial Stability Board’s TCFD recommendations. 
•  Received updates on ethics and business conduct, including whistleblowing to help monitor the management and mitigation 

of business conduct issues as part of the wider controls framework. The Committee noted that there had not been any significant 
breaches of the Company’s Code of Ethical Business Conduct; however, noted that some cases had highlighted opportunities 
for improved controls. The Committee was also pleased to hear that the whistleblowing procedures in place and internal 
procedures remained effective and a number of employee communications would take place in 2020 to improve the 
understanding of these procedures.

•  Received a bi-annual update of compliance with external laws and regulations, including updates on any non-compliance issues 

and steps being taken to improve compliance across the Company. The Committee discussed the controls and mitigating 
actions employed to reduce such instances of fraud and compliance breaches in support of the Group’s overall strategy and 
culture. The Committee noted that the review of enhancements to the Company’s risk, control and assurance framework would 
incorporate the improvement of assurance activities through culture, technology, organisation and reporting.

Financial Reporting 
Going Concern and Viability Statement 
The Committee, in conjunction with the Finance Committee, reviewed 
the Group’s going concern and viability statements (as set out on 
pages 26 and 27) and the supporting assessment reports prepared 
by management. 

The Finance Committee met in May 2020 to discuss the implications 
of COVID-19 to the Group’s going concern and viability statements. 

The current COVID-19 situation has highlighted the interconnectivity 
between risks and the speed at which risks may materialise and 
during this uncertainty, significant work was undertaken to consider 
the Company’s viability statement from additional perspectives. In May 
and June 2020, the Committee reviewed and challenged the viability 
statement and considered the period of assessment used, taking into 
account the COVID-19 events and other external factors in the fast-
changing situation including benchmarking the approach adopted by 
other companies. It also considered individual risk testing, cluster testing 
and the impact of the Company’s response to COVID-19 on business 
plans and financial models. After due consideration, these were 
recommended to the Board in June 2020. The financial statements are 
prepared on a going concern basis such that the Company and the 
Group have adequate resources to remain in operation as per National 
Grid’s Group Treasury policy. 

Statutory reporting framework policy
The Board has ultimate responsibility for effective management of risk 
for the Group including determining its risk appetite, identifying key 
strategic and emerging risks, and reviewing the risk management and 
internal control framework. The Committee, in supporting the Board 
to assess the effectiveness of risk management and internal control 
processes, relies on a number of Company-specific internal control 
mechanisms to support the preparation of the Annual Report and 
Accounts and the financial reporting process. This includes both the 
Board and Committees receiving regular management reports to include 
analysis of results, forecasts and comparisons against last year’s results, 
and assurance from the external auditor. Members of the Executive 
Committee attend quarterly performance reviews to supplement this. 

The Committee is kept fully informed of all new legislation, FRC advice 
and best practice and the requirements of the Code and Disclosure 
and Transparency Rules. Regular reviews in the drafting process 
support the development of an annual report and accounts that 
meets all requirements. 

The Board receives, in advance of the full-year results, a periodic 
SOX report on management’s opinion on the effectiveness of internal 
control over financial reporting. This report concerns the Group-wide 
programme to comply with the requirements of SOX and is received 
directly from the Group SOX and Controls Team and through the 
Audit Committee. 

In relation to the financial statements, the Company has specific internal 
mechanisms that govern the financial reporting process and the 
preparation of the Annual Report and Accounts. The Committee ensures 
that the Company provides accurate, timely financial results and 
implements accounting standards and judgements effectively, including 
in relation to going concern and viability. Our financial processes include 
a range of system, transactional and management oversight controls. 
Also, our businesses prepare detailed monthly management reports 
that include analysis of their results, along with comparisons to relevant 
budgets, forecasts and the previous year’s results. Quarterly performance 
reviews, attended by the Chief Executive and Chief Financial Officer, 
supplement these reviews. Each month, the Chief Financial Officer 
presents a consolidated financial report to the Board.

Fair, balanced and understandable 
The Committee undertook a full and formal review of the content in the 
2019/20 Annual Report and Accounts and recommended the approval 
of the half and full-year financial statements and the Annual Report and 
Accounts to the Board. The review is a well-established and documented 
process involving senior management and the core reporting team. 
To enable the Committee to make this recommendation, the Committee 
considered whether, taken as a whole, the Annual Report and Accounts 
is fair, balanced and understandable. The Committee also considered 
the Company’s compliance with relevant regulatory frameworks and 
the validation of management’s representations to Deloitte. Further, it 
provided oversight of the quality and integrity of the Group’s financial 
reporting and accounting policies and practices. 

As part of its review of the financial statements, the Committee 
considered, and challenged as appropriate, the accounting policies 
and significant judgements and estimates underpinning the 
financial statements. 

This work enabled the Committee to be satisfied that the Annual Report 
and Accounts, taken as a whole, is fair, balanced and understandable 
and provides the necessary information for shareholders to assess the 
Company’s position and performance, business model and strategy. 
This was reported to the Board at its meeting in June 2020.

Risk management and internal control 
Risk management 
The Committee has delegated responsibility from the Board for the 
oversight of the Group’s system of internal control and risk management 
systems. This includes policies, compliance, legislation including 
compliance with SOX and the UK Bribery Act 2010, appropriateness of 
financial disclosures, procedures, business conduct and internal audit. 
As part of the framework across the Group, National Grid’s values – 
“do the right thing”, “find a better way” and “make it happen” – continue 
to communicate and promote a culture of integrity across the business. 

During the year, the Board reviewed the principal risks facing the Group 
(as set out on pages 22 – 25). The Committee provided assurance and 
review of the risk management process to ensure that processes are in 
place to manage risk appropriately. 

Internal Control and Risk Management effectiveness 
We continually monitor the effectiveness of our internal controls and 
risk management processes to make sure they continue to be effective 
and assess them to make sure they remain fit for purpose. Following 
the review over the year the Committee confirmed that the processes 
had the correct authority, expertise and independence and provided 
sufficient assurance to the Company. As the business continues to 
evolve, systems and processes continue to be implemented to support 
this such as the recent deployment of new systems across finance, 
supported by the cyber team. The Committee was satisfied that the 
systems and processes are functioning effectively. 

The effectiveness of internal controls and risk management processes is 
regularly monitored and assessed by the Committee and management 
to make sure they remain robust. This review includes financial, 
operational and compliance controls. The Committee also monitors and 
addresses any business conduct issues or compliance issues. The 
Certificate of Assurance (CoA) process operates via a cascade system 
and takes place annually in support of the Company’s full-year results. 

Corporate Audit supports the Group’s risk management and internal 
controls processes. They deliver an independent and objective approach 
to evaluate and push forward processes. The Global Head of Audit has 
responsibility for the internal audit function and attends all Committee 
meetings, and has access to the Committee Chair when necessary. 

At each of the Committee’s meetings progress is reviewed including 
significant findings and how previous actions have been completed. 
The Committee notes timelines and where actions are overdue, these 
are challenged by the members. Corporate Audit is responsible for 
developing the Audit Plan including engaging in major change 
programmes across the business. The Committee approved the review 
of the Corporate Audit Charter in November 2019 following agreement 
from the Safety, Environment and Health Committee. 

This year, the Committee continued to keep IT controls at the top of its 
agenda and focus, following the appointment of a new Chief Information 
Security Officer. In May 2020, the Committee was informed that the prior 
year significant deficiency in respect of IT controls was closed, following 
work to fully remediate the IT infrastructure environment in the US. 

Audit Committee Chair Transition 
As outlined in the report on page 84, the Nominations Committee 
discussed in 2019 the plan to recruit a Non-executive Director with 
suitable capabilities to replace Mark Williamson as Audit Committee 
Chair when he retires. Following a thorough process, Liz Hewitt was 
appointed to the Board and joined as a member of the Audit Committee. 

Liz is a Chartered Accountant with significant experience in dealing with 
complex and challenging audit issues. She has extensive experience 
as chair of an audit committee previously holding the role with Synergy 
Health plc and Savills plc. Liz currently chairs the Audit Committees of 
Melrose Industries plc, Novo Nordisk A/S and the House of Lords. Further 
details on Liz’s career experience and skills can be found on page 67.

Corporate Governance | Audit Committee

External audit 
The Committee is responsible for overseeing the relationship with the 
external auditor. Mark Williamson meets with the external auditor prior 
to each meeting and outside the meeting cycle on a regular basis. 
•  Deloitte is the external auditor to the Company. 
•  Appointed in 2017 following a formal tender process. 
•  Reappointed at the 2019 AGM for the year ended 31 March 2020. 
•  Audit Committee was authorised by shareholders to set Deloitte’s 

remuneration at the 2019 AGM.

•  Current lead Audit Partner is Doug King and 2019/20 was the third 

year of his term. 

Following consideration of the auditor’s independence and objectivity, 
the audit quality, and the auditor’s performance, the Committee was 
satisfied with the effectiveness, independence and objectivity of Deloitte 
and recommended to the Board its reappointment for the year ended 
31 March 2021.

A resolution to reappoint Deloitte and give authority to the Audit 
Committee to determine their remuneration will be submitted to 
shareholders at the 2020 AGM.

Effectiveness and performance 
As part of the Committee’s responsibilities, a review during the year was 
undertaken to consider the effectiveness of the external auditor and 
ensure that the quality, challenge and output of the external audit 
process is sufficient. 

National Grid’s management take an active engagement in the external 
audit process and recognise the importance of the process. The 
Committee also regularly receives the views of senior management and 
members of the finance team in forming conclusions on effectiveness.

During the year, the Committee: 
•  reviewed the quality of audit planning including approach, scope, 

progress and level of fees; 

•  reviewed the outcome of recommendations from the Deloitte 

Management Letter in 2018/19; 

•  received the Deloitte Management Letter for 2019/20; 
•  held private meetings with Deloitte where management was not 

present; and

•  confirmed that the external audit process by Deloitte had been 

delivered effectively. 

Auditor independence and objectivity 
In addition to the review of effectiveness, the Committee is responsible 
for considering the independence and objectivity of Deloitte. The 
Committee has full oversight of the non-audit services policy and fees 
paid and enforces checks to ensure that employees of Deloitte are not 
appointed to roles in the financial reporting scope within the Company. 

The Committee considered the safeguards in place, including the annual 
review by Corporate Audit, to protect the external auditor’s 
independence. The external auditor reported to the Committee in June 
2020 that it had considered its independence in relation to the audit and 
confirmed that it complies with UK regulatory and professional 
requirements, SEC regulations and Public Company Accounting 
Oversight Board (PCAOB) standards and that its objectivity is not 
compromised. The Committee took this into account when considering 
the external auditor’s independence and concluded that Deloitte 
continued to be independent for the purposes of the external audit and 
confirmed that this recommendation was free from third-party influence 
and restrictive contractual clauses. 

The independence of the external auditor is essential to the provision 
of an objective opinion on the true and fair view presented in the 
financial statements. 

Audit quality 
Regularly throughout the year, the Committee looks at the quality of 
the auditor’s reports and considers its response to accounting, financial 
control and audit issues as they arise. To maintain audit quality, the 
Committee reviews and challenges the proposed external audit plan, 
including its scope and materiality, before approval, to satisfy itself that 
Deloitte has identified all key risks and has developed robust audit 
procedures and communication plans. 

The Committee also meets with Deloitte twice a year without 
management present, providing the external auditor with the opportunity 
to raise any matters in confidence and have an opportunity for open 
dialogue. This meeting also gives the Committee a chance to monitor 
the performance of the lead Audit Partner both inside and outside 
Committee meetings. 

Non-audit services
In line with the FRC’s Ethical Standard and to help protect the external 
auditor’s objectivity and independence, we have a policy governing 
Deloitte’s provision of non-audit services. In March 2020, the Committee 
approved amendments to the policy in line with the mandatory FRC 
changes outlined in the Revised Ethical Standards, published in 
December 2019. 

The cap on the total fees that may be paid to the external auditor for 
non-audit services in any given year is 70% of the average audit fees 
paid in the last three financial years. Following Deloitte’s appointment 
in 2017 this is the first year that this is effective on the Company. 

To help protect auditor objectivity and independence, the provision of 
any non-audit service by the external auditor requires prior approval. 
The policy allows for certain specified services to be undertaken under 
‘pre-approval’ by the Audit Committee where we believe there is no 
threat to the auditor’s independence and objectivity, the service has 
been reviewed by the CFO, and where fees do not exceed £50,000. 
These services are limited to:
•  audit, review or attest services. These are services that generally 
only the external auditor can provide, in connection with statutory 
and regulatory filings. They include comfort letters, statutory audits, 
attest services, consents and assistance with review of filing 
documents; and

•  other areas, such as provision of access to technical publications.

Our policy requires management to present a list of all non-audit work 
requests to the Committee at each official meeting to ensure the 
Committee is monitoring all non-audit services provided. Non-audit 
service approvals during 2019/20 principally related to comfort letters 
associated with debt offerings. Work performed by Deloitte during the 
year (which necessarily also includes engagements approved by the 
Committee in 2018/19) included pre-implementation governance reviews 
associated with the new UK financial record system (MyFinance) and  
a final element of market-related advisory work with the UK property 
division. 

External auditor fees 
The amounts payable to the external auditor, Deloitte, in each of the past 
two years were:

Audit and non-audit services (£m) 

18.0
1.1
16.9

18.6

3.3

 Audit services
 Non-audit services

Total billed non-audit services provided by Deloitte during the year 
ended 31 March 2020 were £1.1 million, representing 7% of total 
audit and audit-related fees. In 2018/19, non-audit services totalled  
£3.3 million (22% of total audit and audit-related fees).

Further information on the fees paid to Deloitte for audit, audit-related 
and other services is provided in Note 4 to the financial statements on 
page 136.

Total audit and audit-related fees include the statutory fee and fees 
paid to Deloitte for other services that the external auditor are required 
to perform, such as regulatory audits and SOX attestation. Non-audit 
fees represent all other services provided by Deloitte not included in 
the above.

Corporate Governance

Finance Committee

The Committee will continue to receive regular 
updates on implications as the pandemic 
continues to progress.

Prior to the emergence of COVID-19 other 
key focuses for the Committee included the 
external regulatory and political environments, 
and significant time was spent considering the 
implications of Brexit and the resulting market 
impact following the UK’s exit from the 
European Union on 31 January 2020.

In January 2020, the Committee members 
hosted an informal question and answer 
session with employees from the Tax, Pensions 
and Insurance teams in the UK, to further 
increase workforce engagement and to 
encourage a dialogue between the Committee 
and employees whom the Committee would 
not normally have the opportunity to engage 
with at meetings. Following the success of the 
January session, similar engagement sessions 
are planned to take place in 2020 and thought 
is being given as to how these can take place 
around COVID-19 restrictions.

Treasury
RIIO-2 was a key focus for the Committee over 
the year and regular updates on the financial 
implications of RIIO-2 were received including 
an additional presentation focused on the 
financial aspects of the RIIO-2 business plan. 
Discussions took place on the assumptions 
and parameters set by Ofgem and proposed 
financial frameworks, ahead of the RIIO-2 
business plan submission in November 2019. 

The Committee provided continued oversight 
over management decision-making and 
execution of financial risk. The Company 
reviewed the management of the Group’s 
financial risk appetite; as a result, the Committee 
approved minor policy changes to funding risk, 
liquidity risk, counterparty credit risk, credit 
rating risk and foreign exchange translation risk. 

Management provided regular updates on 
strategy formulation for the future, including 
investment requirements for the business, 
credit ratings, dividend policy and LIBOR 
transition. The Committee was pleased to 
receive details on the execution of new bonds 
during the year, approving the year’s financing 
strategy and receiving regular updates as 
financing is executed. Approval was also given 
to a hybrid refinancing strategy with hybrid 
bonds issued across two tranches in NGG 
Finance plc. 

A Green Financing Committee chaired by the 
Group Treasurer was established in December 
2019 to support the Company’s sustainability 
strategy and Green Financing Framework 
detailed on page 58 as the Group works 
towards its net zero ambition. In January 2020 
the Company launched its first green bond, 
which was well received by the market. 

In November, the Committee invited a credit 
rating agency to the Committee to provide an 
insight into methodologies used for ratings, the 
credit landscape in the UK and US for regulated 
utilities and the potential impact of Brexit. 

Insurance
The Committee received regular insurance 
updates which considered the current shape 
of the insurance market and how the Company 
was benchmarked against other organisations 
in relation to the Company’s approach to 
insurance renewals in April 2020. 

The Committee monitored the evolution and 
efficiency of cyber insurance as part of our 
cyber insurance programme. This continues to 
be a fast-growing area of the global insurance 
market and external advisors are due to 
present to the Committee in July 2020 to 
provide additional external insight. 

At its meeting in April, the Committee 
discussed the impact of COVID-19 on the 
insurance market and will be monitoring the 
insurance risk appetite closely throughout 
the year. 

Tax
The Committee has continued to monitor the 
potential tax impacts of Brexit and received a 
focused update on implications from a tax 
perspective throughout the year. An update 
was also received concerning the UK Finance 
Bill 2019/20 and the potential impact on the 
Company, particularly around the impact of the 
changes to the IR35 rules. The Committee will 
continue to monitor developments in this area. 
In January 2020, external advisors presented 
to the Committee on the evolving Tax 
Transparency debate.

The Company also continues to give focus to 
the changing tax landscape, particularly in 
relation to the effect of digitisation, in line with 
the business-wide digitalisation ambition. The 
Tax team continue to inform the Committee of 
external developments in relation to tax authorities 
to enable continued best practice and how 
technology can be leveraged in this area.

Pensions
In 2018/19 the Committee commenced plans 
to consider de-risking the UK pension plans, 
to more closely match the assets and liabilities. 
Throughout this year, the Committee 
considered these plans further and approved 
appropriate solutions to de-risk the Company’s 
pension arrangements, enabling the National 
Grid UK Pensions Scheme to enter into buy-in 
arrangements with both Legal & General 
and Rothesay, supporting the Company’s 
long-term strategy to reduce the level of risk 
within its pension arrangements. 

In July 2019, external advisors presented to the 
Committee on the UK pension landscape and 
trends in the market, including the increased 
decline in the defined benefit schemes across 
the market and the increase in utilisation of 
defined contribution schemes. The Committee 
received a further presentation from external 
advisors in April 2020 focusing on the US 
pension landscape and trends in the market 
alongside the impact of COVID-19 on the 
pensions market.

Looking forward
The Committee will remain focused on 
ensuring the Company is effectively managing 
financial risk, working closely with the Audit 
Committee with particular focus on impacts 
due to the COVID-19 pandemic as it continues 
to progress globally.

the Group, focusing on key areas such as treasury, 
tax, pensions, insurance, investments and 
commodities. The Committee also convened 
for an additional presentation in May 2019 
which focused on the financial impacts of the 
RIIO-2 business plans. 

Towards the end of the year the impact to 
global markets of the COVID-19 pandemic 
became clearer and the Committee held 
additional COVID-19 focused meetings in April 
and May 2020. Significant consideration was 
given to the financial implications of the global 
pandemic on the Company. This included 
financial scenario planning and risk mitigation. 
At its May meeting the Committee considered 
the Going Concern assumption of the 
Company, considering the uncertainties posed 
by COVID-19 and the additional focus by 
regulators. This consideration included a range 
of cash flow outcomes, the Company’s ability 
to access existing undrawn facilities alongside 
its ability to access long-term debt markets 
and short-term cash positioning.

Review of the year and COVID-19
During the year, the Committee met six times 
to undertake its oversight responsibilities for 
reviewing the strategies, policies, initiatives, 
risk exposure, targets and performance of the 
Company in relation to safety, environment, 
health and wellbeing. Two of these meetings 
were scheduled specifically to monitor the 
potential safety issues surrounding the lifting 
of the downstate New York gas moratorium. 
The Committee considered the Company’s 
contingency proposals to maintain security 
of supply throughout the winter, including 
the potential to add new CNG sites to meet 
demand, and challenged the associated risks. 

Towards the end of the year we have seen the 
acceleration of the global COVID‑19 pandemic; 
the health and wellbeing of all employees and 
contractors has been of paramount importance 
during these challenging and unprecedented 
times. The Committee has and will continue to 
focus on ensuring the strategies and policies 
being implemented across the business 
adequately protect the health, safety and 
wellbeing of everyone.

Committee member induction
Since joining the Committee in 2019, both 
Amanda Mesler and Earl Shipp have undertaken 
site visits in the UK and US as part of their 
induction. These site visits provided a useful 
insight into the Company and the opportunity 
to gain a wider perspective of National Grid 
and to meet and engage with a variety of 
employees to discuss their views on safety, 
environment and health on site and throughout 
the Company. The site visits are an important 
way of demonstrating Company safety, health 
and environment leadership and are a way to 
build Committee knowledge, skills and 
strengthen discussion around issues.

The Committee also welcomed Liz Hewitt as a 
member in January 2020. Liz brings excellent 
experience to the Committee and her wealth 
of knowledge in wide areas of business will 
add diversity and value to our discussions. 

Safety
In line with the Company’s key values, safety 
remains a top priority for the Company and 
the Committee. We have seen improvement 
in the Injury Frequency Rate in the UK, which 
remains world class; however, we must never 
become complacent and improvements still 
need to be made. The Committee was deeply 
saddened when in July 2019 a National Grid 
employee in the US was involved in a fatal 
traffic accident while working on behalf of the 
Company. The Committee has been kept up 
to date on the investigations surrounding this 
tragic incident and has strongly endorsed the 
Company’s commitment to ensuring that key 
lessons learned have been communicated to 
all our workforce. As a result, the Company 
rolled out a Group‑wide safety intervention to 
remind our workforce of the Company’s Safety 
Ambition. The feedback from the intervention 
has been positive and has encouraged our 
workforce to continue the important 
conversation around safety by discussing 
within teams recent safety incidents and ways 
to prevent future occurrences. The Committee 
will continue to monitor the implementation of 
these lessons learned. 

Further to my update last year about the 
employee safety culture survey, this year the 
Committee received an update on the results 
of the survey including the new plans built 
from the actions identified, which will help the 
Company to continue on its journey from a 
calculative safety culture to a more proactive 
safety culture. 

Gas safety and reliability
A significant amount of the Committee’s time 
this year has been spent on gas safety and 
reliability in the US. The post‑work stoppage 
initiatives following the Massachusetts labour 
dispute were reviewed, including monitoring 
the closure of open work actions and the 
implementation of new processes to ensure 
regulatory compliance. Regular updates were 
provided which identified areas of focus and 
improvement and the Committee discussed 
and considered risks around these. The 
Committee also reviewed and challenged the 
proposed plan to improve the safety of US 
LNG plants. The Committee will continue to 
monitor progress of the gas safety and 
reliability initiatives over the coming year. 

National Grid’s net zero commitment
Sustainability is a key focus and the Committee 
has been pleased to see the increasing 
prominence of this issue internally and 
externally. The Company recognises it has 
a critical role to play in the decarbonisation 
of the energy system and the importance of 
setting a net zero ambition for the Company’s 
own emissions, which aligns with its strategy 
of a cleaner future. In November 2019, the 
Committee endorsed the Company’s new 
target to reduce its own direct greenhouse gas 
emissions to net zero by 2050. The Committee 
reviewed the Company’s high‑level plan to 
achieve this and in January 2020 approved 
ambitious interim targets to reduce its direct 
emissions by 80% by 2030 and 90% by 2040. 
The Committee will continue to closely monitor 
and challenge the Company’s progress against 
the action plan and the implementation of the 
Company’s wider strategy around sustainability 
to achieve long‑term carbon reduction targets. 

Employee health and wellbeing
In January 2020, the Committee received an 
update in relation to the Company’s progress 
on its health and wellbeing strategy. It was 
noted that a transition had been made by the 
Company in its strategy from a disease‑based 
campaign towards a more holistic approach, 
with a wider range of health and wellbeing 
factors facing the workforce being considered. 
As part of the strategy, the Committee has 
continued to track the impact of musculoskeletal 
injuries (MSK) and its effect on employees. 
The Committee was pleased to see that as a 
result of physiotherapy services being available 
to UK employees as well as holding 20 MSK 
workshops across 11 locations, the sickness 
absence risk, in relation to MSK, had dropped 
from the third to fifth highest days lost over the 
past calendar year. Progress continues to be 
made in relation to mental health awareness 
and prevention activities. With the ongoing 
COVID‑19 pandemic the Committee will 
monitor the implementation of wellbeing 
policies and the impact on our workforce; this 
will be kept under review over the coming year 
to ensure that appropriate health and wellbeing 
campaigns and procedures are implemented.

Corporate Governance

Nominations Committee

Senior leadership
Following Dean Seavers stepping down from 
his role as Executive Director in November 
2019, Badar Khan (previously Group Director, 
Corporate Development and National Grid 
Ventures) stepped in as Interim President of 
the US business. Jon Butterworth (previously 
COO of National Grid Ventures) stepped in as 
Interim Managing Director of National Grid 
Ventures. Following success in their interim 
positions, the Committee approved the 
permanent appointment of Badar Khan as 
President of the US business and Jon 
Butterworth as permanent Managing Director 
of National Grid Ventures on 2 April 2020. 

Non-executive Director – Jonathan Silver
The appointment of Jonathan Silver began in 
2018 with the appointment of Korn Ferry, a 
search consultancy firm that does not have 
any other connection with the Company or 
individual directors. The Committee reviewed 
and agreed the Non-executive Director 
candidate profile which was formulated taking 
into account the current skills of the Board 
members and data analysis received from the 
2018 external Board evaluation process. This 
highlighted the additional need to strengthen 
the Board’s US regulatory, equity and financial 
experience. Having conducted an initial search, 
a list of potential candidates were selected for 
the first interview with the Chairman. It was 
agreed that a sub-group of the Committee 
(Nora Mead Brownell, Therese Esperdy and 
Mark Williamson), and John Pettigrew would 
interview the final candidates from the short 
list recommended by the Chairman. The 
Committee agreed the preferred candidate and 
made a recommendation to the Board in April 
2019. On 16 May 2019, following a thorough 
and rigorous process, the Board welcomed 
Jonathan Silver as a Non-executive Director 
to the Board and as a member of the Finance, 
Remuneration and Nominations Committees. 

Non-executive Director – Liz Hewitt
In April 2019, the Committee discussed 
recruiting a further Non-executive Director with 
capabilities to succeed Mark Williamson as 
Audit Committee Chair once he retired. The 
Inzito Partnership, who do not have any other 
connection with the Company or individual 
directors, was appointed to support the 
recruitment of this role. The Committee agreed 
the Non-executive Director candidate profile 
and a short list of potential candidates was 
then drawn up. First-stage interviews were 
conducted by the Chairman and final interviews 
were conducted by a sub-group of the 
Committee (Therese Esperdy, Paul Golby and 
Mark Williamson), John Pettigrew and Andy 
Agg. In November 2019, the Committee agreed 
that Liz Hewitt was the preferred candidate and 
made a recommendation to the Board. Liz has 
a strong background in dealing with complex 
and challenging audit issues. The Board 
welcomed Liz Hewitt as a Non-executive 
Director and member of the Audit, Safety, 
Environment and Health, and Nominations 
Committees on 1 January 2020. 

When considering the recruitment of new 
Directors, the Committee adopts a formal 
and transparent procedure which takes into 
account the skills, knowledge and level of 
experience required as well as diversity. For 
both appointments the candidate pool was as 
diverse as possible ensuring the Committee 
had options to balance the diversity on the 
Board. The effectiveness of the Board is also 
reviewed through the annual Board evaluation; 
see page 74 for further information.

Sir Peter Gershon
Chairman and Committee Chair

Key areas of focus in 2019/20:
•  Board and Committee composition; 
•  Chairman succession; and 
•  Senior leadership succession. 

Key areas of focus in 2020/21:
•  Chairman succession and onboarding; 
•  Review of senior leadership succession 

policy; and

•  Board and Committee composition. 

Review of the year
The Committee met seven times during the year 
to undertake its responsibilities in reviewing the 
leadership needs of the Company, based on 
the structure, size and composition of the 
Board and its Committees. In addition, the 
Committee reviews and oversees succession 
planning for Directors and senior management 
and makes recommendations, as appropriate, 
to the Board. 

Succession planning and 
Board composition 
A key focus for the Committee this year has 
been succession planning. The Committee is 
responsible for ensuring that the Company is 
headed by a high-quality Board and senior 
management team and recognises that the 
process of building a strong and effective Board 
and senior management team requires a good 
balance of continuity and refreshment. During 
the year, Board members assessed the skills 
and areas of expertise that they brought to the 
boardroom to ensure effectiveness in providing 
good corporate governance and strategic 
oversight. This assessment will further aid in 
identifying gaps and areas of strengthening 
needed when appointing members in the 
future. The Committee has also borne the 
Code in mind in its deliberations throughout the 
year to ensure that we have in place a strong 
Board and senior management team with the 
breadth of skills, experience and perspectives 
necessary to reflect the changing demands of 
the business and Company strategy. The 
Committee will continue to monitor the skills 
and capabilities, and length of tenure of Board 
members to ensure that broad and relevant 
expertise is evident and will recommend further 
appointments if necessary. Further information 
on our individual Directors’ skills and 
capabilities can be found on pages 66 and 67.

Board diversity objectives 

Objectives

Progress

The Board aspires to meet the target of 33% of Board and Executive 
Committee positions, and direct reports to the Executive Committee,  
to be held by women in 2020.

Objective met: there are currently 33.3% women on the Board, 33.3% 
women on the Executive Committee and 33.8% women direct reports to 
the Executive Committee.

The Board aspires to meet the Parker Review target for FTSE 100 boards 
to have at least one director from a non-white ethnic minority by 2021. 

We continually aspire to exceed this target and we take gender diversity 
into consideration in all our Executive and Non-executive Directors 
searches. All appointments are however made on merit. 

Objective met: we currently have one Director from a non-white ethnic 
minority on the Board. Additionally, our mandatory requirement for a 
diverse candidate pool should facilitate the opportunity to recruit further 
from non-white ethnic minorities. 

Terms of reference
Following the introduction of the Code, 
the Committee terms of reference have been 
revised to align with the new requirements. 
These reflect the broadening of the 
Committee’s responsibility for overseeing 
the development of a diverse pipeline of 
high-performing potential successors to 
senior management and keeping under 
review the leadership and succession 
needs of the Company. 

Diversity and Board diversity policy 
National Grid supports the creation of an 
inclusive and diverse culture which we believe 
supports the attraction and retention of 
talented people, improves effectiveness, 
delivers superior performance and enhances 
the success of the Company. 

Our Board diversity policy (Policy) reflects our 
continued commitment to promote an inclusive 
and diverse culture and we value diversity of 
thought, skills, experience, knowledge and 
expertise including of educational and 
professional backgrounds, alongside diversity 
criteria such as gender, ethnicity and age. 

The Policy applies to the Board, Executive 
Committee and direct reports to the 
Executive Committee.

As set out in the Policy:
•  all Board appointments and succession plans 
are made on merit and objective criteria, in 
the context of the skills and experience that 
are needed for the Board to be effective 
and to guard against ‘group think’;

•  we will only engage executive search firms 
who have signed up to the UK Voluntary 
Code of Conduct on Gender Diversity; and 
•  we will continue to make key diversity data, 

both about the Board and our wider 
employee population, available in the 
Annual Report and Accounts. 

Chairman’s succession
Mark Williamson 
Senior Independent Director
Throughout the year I have chaired the 
Nominations Committee, without Sir Peter 
Gershon present, to discuss the Chairman’s 
performance, tenure and succession. In last 
year’s report I reported that Sir Peter’s 
tenure may be extended beyond the 
recommended nine-year term in order to 
conclude the RIIO-2 process. This was 
agreed following discussion with 18 of our 
largest shareholders, who unanimously 
supported the extension. In January 2020, 
Sir Peter Gershon formally announced 
his intention to step down as Chairman 
and retire from the Board following the 
appointment of a suitable successor. To 
manage a smooth transition, we intend to 
appoint a Chairman designate to the Board. 
A search process for the next Chairman is 
currently underway, supported by Russell 
Reynolds, and the Committee considered a 
long-list of potential candidates at the 
January 2020 meeting. Over the next few 
months, the Committee will agree a shortlist 
of preferred candidates and a full explanation 
of the search and appointment process will 
be reported in next year’s report.

We will continue to review our progress 
against the Policy and report on our objectives 
(set out above) annually in the Annual Report 
and Accounts. The Committee will be reviewing 
this Policy throughout the year to ensure it 
remains up to date and relevant. 

Examples of the initiatives to promote and 
support inclusion and diversity throughout 
our Company are set out on page 53. 

Sir Peter Gershon
Chairman and Committee Chair

Director tenure
The Committee believes that Non-executive 
Directors should generally stay in role no longer 
than nine years, in line with the Code; however, 
the Committee may determine that on 
occasion it is in the Company’s best interest for 
a Director with particular skills, knowledge and 
experience to stay beyond the nine-year term. 
It is proposed that Paul Golby stay for a limited 
extension beyond 1 February 2021 in order 
for the Board to maintain the knowledge 
and experience required to conclude the 
RIIO-2 process.

Talent pipeline – Senior leadership 
succession
The Board and Nominations Committee support 
and encourage initiatives that strengthen the 
talent pipeline within the Company. Over the 
last 12 months we have seen several changes 
within the Executive and senior leadership 
team as we refresh the skills and capabilities 
needed to achieve our long-term strategy. The 
Committee has considered whether the talent 
pipeline and the collective strength of the 
current leadership and senior management 
bench in the business is strong enough in its 
key positions, specifically in relation to handling 
crises and ensuring the business is fit for the 
future. It is an area of focus for the Committee 
to ensure that the required pace of change 
facilitates strong and effective succession 
across the Board and the wider business. 

The Executive Committee continues to meet 
regularly to discuss the succession pipeline 
and health of the talent pool further down 
the organisation; as a result, a number of 
individuals have been identified as potential 
successors to key positions. Our senior leaders 
below the Board were invited to participate in the 
‘Energise Our Business’ programme this year 
which combines flexible online development 
and peer learning with more traditional 
development activity. The Committee has 
developed a strong understanding of executive 
talent requirements and the capabilities we 
need for the future to fit with our purpose, 
vision and values. This has been evidenced by 
the appointment of Badar Khan as President 
of the US Business and Jon Butterworth as 
Managing Director of National Grid Ventures. 
The Committee regularly reviews the 
development plans of the high potential senior 
leaders below the Board. The Board has also 
met with high-potential employees both in the 
UK and the US on several occasions during 
the year.

3.  Composition, Succession and Evaluation
Composition
The Board believes it operates effectively with an appropriate balance 
of independent Non-executive and Executive Directors who have the 
right balance of skills, experience, independence and knowledge of 
the Company. Details of our Board, their biographies and Committee 
membership are set out on pages 66 and 67 and fuller biographies are 
available on our website. Board and Committee attendance during the 
year to 31 March 2020 is set out on page 69. The size and composition 
of the Board and its Committees is kept under review by the 
Nominations Committee to ensure the appropriate balance of skills, 
experience, independence and knowledge. The Committee also 
monitors the expertise of the Board and will recommend further 
appointments if desirable. The appointment of Liz Hewitt in January 
2020 ensures the Board has a Non-executive Director with the required 
capabilities and expertise to succeed as Audit Committee Chair. The 
independence of the Non-executive Directors is considered at least 
annually along with their character, judgement, commitment and 
performance on the Board and Board Committees. The Board took into 
consideration the Code and indicators of potential non-independence, 
including length of service. Following due consideration, the Board 
determined that all Non-executive Directors were independent in 
character and judgement.

Succession
The Nominations Committee, which comprises the Chairman and 
Non-executive Directors, leads the process for Board appointments and 
makes recommendations to the Board. The Nominations Committee 
also has responsibility for ensuring that plans are in place for orderly 
succession to both the Board and senior management positions as well 
as overseeing the development of the talent pipeline to ensure that the 
future leadership needs of the Company are considered and these fit 
the culture and forward-looking strategy of the Company.

Each Director is subject to election at the first AGM following their 
appointment, and re-election at each subsequent AGM. Following 
recommendations from the Nominations Committee, the Board 
considers whether all Directors continue to be effective, committed 
to their roles and have sufficient time available to perform their duties. 
In April 2020 the Nominations Committee confirmed to the Board that 
all Directors continued to perform their duties in accordance with the 
principles above. Succession planning is ongoing for those members 
of the Board who are approaching the nine-year tenure recommendation. 

Evaluation
The 2019/20 performance evaluations of the Board, Board Committees 
and individual Directors were carried out internally with consideration 
given to composition, diversity, how effectively members work together 
to achieve objectives and effectiveness of decision-making. You can 
read more about this on page 74.

Chairman’s Performance
As part of our annual evaluation process, Mark Williamson, as Senior 
Independent Director, led a review of the Chairman’s performance. 
At a private meeting, the Non-executive Directors, with input from the 
Executive Directors, assessed his ability to fulfil his role as Chairman 
and considered the arrangements he has in place to fulfil his role. They 
concluded that the Chairman showed effective leadership of the Board 
and his actions continued to influence the Board and wider organisation 
positively. They also confirmed it would be in the Company’s best 
interest for Sir Peter Gershon to continue in his role as Chairman during 
the conclusion of the RIIO-2 regulatory process.

At the end of the year, the Chairman held performance meetings with 
each Board member to discuss their contribution and performance over 
the prior year, including how effectively they worked together to achieve 
objectives and any training and development needs. Following these 
meetings, the Chairman confirmed to the Nominations Committee that 
he considered each Director to have demonstrated a commitment to the 
role and that their contribution continued to be effective.

The statement below, together with the rest of the Corporate Governance 
report, explains the main aspects of the Company’s governance structure 
to give a greater understanding of how the Company has applied the 
principles in the UK Corporate Governance Code 2018 (the Code). For 
the year ended 31 March 2020, the Board considers that it has complied 
in full with the provisions of the Code, available at www.frc.org.uk. 
The Corporate Governance report also explains compliance with the 
Disclosure Guidance and Transparency Sourcebook. The index on 
page 87 sets out where to find each of the disclosures required in the 
Directors’ Report in respect of Listing Rule 9.8.4 R.

1.  Board Leadership and Company Purpose
Our Board is collectively responsible for the effective oversight and 
long-term success of the Company and champions our purpose, vision, 
values and desired culture, ensuring consistency with our workforce 
policies and practices. It also determines the strategic direction, business 
plan, objectives, principal risks and viability of the Company and sets the 
governance structure that will help achieve the long-term success of the 
Company and deliver sustainable shareholder and stakeholder value.

The Board sets the risk appetite and principal risks for the Company 
and takes the lead in areas such as safeguarding the reputation of the 
Company and its financial policy, as well as making sure we maintain 
a sound and prudent system of internal control and risk management. 
Since the onset of the COVID-19 pandemic, we have received updates 
on the impact on our UK networks that are managing the rapid and 
unprecedented decrease in energy demand across all UK networks 
and in May 2020 it was agreed to add COVID-19 as a principal risk. 
The Board also agreed to add a new climate change principal risk in 
March 2020. 

There is a clear schedule of matters reserved for the Board and 
schedule of delegation, which were both reviewed and updated in 
January 2020. The schedule of matters reserved for the Board is 
available on our website, together with other governance documentation.

The Board actively engages with shareholders and stakeholders, 
including employees, on a regular basis. Further information on how the 
Board has effectively discharged this responsibility can be found on 
pages 44 – 47.

2.  Division of Responsibilities
The Chairman, who was independent on appointment, is responsible 
for the leadership and management of the Board and its governance. 
He makes sure the Board is effective in its role by promoting a culture of 
openness and debate, facilitating the effective contribution of all Directors 
and helping to maintain constructive relations between Executive and 
Non-executive Directors. The Chairman sets the Board’s agenda making 
sure consideration is given to the main challenges and opportunities 
facing the Company, and adequate time is available to discuss all 
agenda items, including strategic issues. This particular area was 
reviewed as part of the internal Board evaluation. For further information 
on the Chairman’s independence and tenure, please see page 85. 

The annual evaluation of our Board considers the composition, including 
the combination of Executive and independent Non-executive Directors, 
to ensure there is no dominant decision-making. The Board supports 
the separation of the roles of the Chairman and Chief Executive. The key 
responsibilities are clearly documented and reviewed when appropriate. 
See our website for more details.

Non-executive Directors are advised of the time commitment and travel 
expected from them on appointment. External commitments, which may 
impact existing time commitments, must be agreed with the Chairman 
prior to appointment and during their time on the Board. As part of the 
Chairman’s succession, potential candidates are notified of the expected 
time commitment at the beginning of the process. Details of external 
appointments are set out in the biographies on pages 66 and 67 and on 
our website. Independent of management, our Non-executive Directors 
bring diverse skills and experience vital to providing strategic guidance, 
constructive challenge and debate. See our website for the matters 
reserved for the Board schedule.

The Group General Counsel and Company Secretary makes sure that the 
Board has access to the necessary policies, processes and resources 
required to operate effectively and efficiently. She is also responsible for 
ensuring that timely information is provided and advises and supports 
the Chairman and the Board on all governance matters.

with the UK Corporate Governance Code 2018

4.  Audit, Risk and Internal Control
Under the Disclosure and Transparency Rules and the Code, the 
composition and competence of the Audit Committee was considered by 
the Nominations Committee at its April meeting. The Board confirmed the 
recommendations of the Nominations Committee: that all members of 
the Committee are independent (including the Chair of the Committee), 
that Mark Williamson, as a chartered accountant, is considered to have 
competence in accounting, and that the Committee, as a whole, has 
competence relevant to the sector in which it operates.

The requirement for Directors to state that they consider the Annual 
Report and Accounts, taken as a whole, is fair, balanced and 
understandable remains a key consideration in the drafting and review 
process. The coordination and review of the Annual Report and Accounts 
is conducted in parallel with the formal audit process undertaken by the 
external auditors and the review by the Board and its Committees. The 
Board is satisfied that the current policies and procedures in place ensure 
the independence and effectiveness of the internal and external audit 
functions. Further details can be found on page 81.

The drafting and assurance process support the Audit Committee’s 
and Board’s assessment of the overall fairness, balance and clarity of 
the Company’s position and prospects as detailed in the Annual Report 
and Accounts, and the statement of Directors’ responsibilities as set 
out on page 109.

The Board has carried out a robust assessment of the nature and extent 
of the principal and emerging risks facing the Company in achieving its 
long-term strategic objectives, including those that would threaten the 
business model, future performance, solvency or liquidity. Further details 
can be found on pages 22 – 27.

The Board also sets the Company’s risk appetite, internal controls and 
risk management processes. The Board monitors the Company’s risk 
management, internal control systems and framework and undertakes 
a review of their effectiveness annually. The activities of the Audit 
Committee, which assists the Board with its responsibilities relating 
to risk and assurance, are set out on pages 76 – 81.

5.  Remuneration
The Remuneration Committee, comprised entirely of Independent 
Non-executive Directors, is responsible for recommending to the Board 
the remuneration policy for Executive Directors, the Chairman and senior 
management, and the implementation of this policy. The aim is to align 
the remuneration policy to the long-term Company strategy and key 
business objectives that will promote long-term sustainable success. 
Our policy is reviewed against workforce remuneration and 
performance, and is designed to reflect our shareholders’, customers’ 
and regulators’ interests. 

The Directors’ Remuneration Report on pages 88 – 107, sets out the 
work of the Remuneration Committee, its activities during the year and 
further details on how our Remuneration Policy is implemented including 
the remuneration of Non-executive Directors. Executive Remuneration, 
including alignment to broader workforce pay policies has been 
discussed at employee voice engagement sessions, along with gender 
pay reporting. These topics will remain key areas for discussion as we 
continue our programme of engagement into 2020/21. 

For more information regarding our policy on the Executive Directors 
pension contribution/allowance and the alignment to the workforce, 
please see page 89 of the Directors’ Remuneration Report.

Corporate Governance

Directors’ Remuneration Report

Annual statement from the Remuneration Committee Chair

Introduction
Last year, our shareholders approved the new Directors’ Remuneration 
Policy for the period from 2019, with 97.03% votes in favour. At the same 
time, the Directors’ Remuneration Report received 96.53% votes in 
favour. The Remuneration Committee and the whole Board are grateful 
to shareholders for their support for our Policy and our implementation 
of it. As a company, our aim is to ensure transparency with our 
shareholders and all stakeholders in what we do, particularly with regard 
to governance and remuneration. The Committee fully recognises the 
central importance of these areas for National Grid’s reputation, and the 
strong interest of shareholders in our standards and performance. Last 
year’s vote followed extensive consultation with our major institutional 
shareholders in light of which we put forward proposals that were 
approved at the AGM. This year we are not seeking approval of a new 
Policy, although through the annual advisory vote we are seeking your 
support for our implementation of the Policy during 2019/20. We are 
planning to seek your approval of a new Policy next year in light of 
decisions to be made by Ofgem during the year regarding the next 
regulatory period (RIIO-2) commencing April 2021. As we have done 
previously, we will consult with major institutional shareholders before 
putting forward our proposals.

Review of decisions made during the year
Annual Performance Plan (APP)
National Grid again delivered good financial performance for the year, 
with Group underlying Profit before Tax of £2,493 million, Underlying 
Earnings per Share of 58.2 pence and Group Return on Equity of 
11.70%; and the Directors have recommended an increase in the final 
dividend in line with our stated policy. Against this background, the 
Group financial metrics for the APP (impacting the CEO and CFO) 
represented 79.4%, a little over half way between target and stretch 
performance. The financial outcome for the Executive Director, UK was 
58.3%, just ahead of target performance, reflecting lower UK-specific 
financials versus Group particularly on RoE. The financial performance 
metrics for the APP are based on financial results, with technical 
adjustments made in line with past practice in respect of currency 
adjustments, unbudgeted pension costs, scrip dividend dilution and 
storm damage repair costs. 

The final APP outcomes (which incorporate assessments against 
individual objectives and financial performance) have, however, had 
one adjustment affecting all staff eligible for APP awards. With the 
bulk of colleagues working remotely due to COVID-19 restrictions, and 
heavily focused on maintaining continuity of service and supply to our 
customers, it would have been difficult for in-depth annual personal 
performance reviews to be undertaken in the normal way. The Committee 
therefore agreed with senior management that, across the Group, the 
individual component under the APP would be capped at the lower of 
actual and target, which is equal to 50% of maximum. The Committee 
has also applied this principle to the Executive Directors and other senior 
executives; the unadjusted individual scores for the Executive Directors 
are shown on pages 98 and 99, from which it can be seen that the 
outturn for the individual objectives of all current Executive Directors 
has been reduced in light of this approach. 

Coupled with the financial measures for the APP, the overall outcome 
for the CEO and CFO is 88.3% of salary, and for the Executive Director, 
UK 69.8% of salary, in each case out of a maximum potential of 125% of 
salary. In its assessment of the overall performance of John Pettigrew 
and the level of APP outcome for him for the year, the Committee gave 
careful consideration to the issues arising from the decision to impose 
a moratorium on new gas supply connections in National Grid’s service 
territory in downstate New York (KEDNY/KEDLI). Although this was an 
operational decision taken by the Group’s US leadership in response to 
a potential shortfall in gas supplies coming into the region, the Committee 
and John agreed that, as CEO, he was ultimately accountable for the 
adverse financial and reputational consequences suffered by the 
Company. The Committee also recognised the subsequent outstanding 
leadership that John had given in reaching a settlement with the New York 
authorities and in actions taken to address the situation. Accordingly, 
the Committee and John agreed that it would be appropriate for John 
to donate 20% of his APP award (net of tax) when it is paid in July to 
a charity involved in the emergency COVID-19 response in our US 
service territories.

In reaching its overall decisions on the APP, the Committee took 
account of Environmental, Social and Governance (ESG) considerations, 
including those related to COVID-19, noting in particular that no employees 
have been furloughed, no compulsory redundancies or pay reductions 
have been made, and trade union agreements have been honoured.

Corporate Governance | Directors’ Remuneration Report

Annual statement from the Remuneration Committee Chair continued

Long Term Performance Plan (LTPP)
The performance period for the 2017 LTPP ended on 31 March 2020, 
with a vesting outcome of 84.9% of the maximum potential (350% for 
the CEO and 300% for other Executive Directors). This outturn was 
based on our performance measures of Group Return on Equity and 
Group Value Growth, with adjustments in respect of inclusion of the value 
created from the sale of the residual interest in the UK Gas Distribution 
business and revised timing of UK tax payments. More details on the 
performance measures are set out on page 100. The Committee 
reviewed whether there were any factors which might cause it to 
reduce the vesting levels, including compliance with the dividend policy, 
but concluded after careful consideration that the vesting levels fairly 
reflected performance over the performance period, and that the 
additional two-year holding period and significant shareholding 
requirements appropriately align interests with shareholders, 
particularly through COVID-19 uncertainty.

I noted last year that our recently appointed CFO’s pension allowance 
was already set at 20% of base salary at the time of his appointment. 
Also, as reported last year, our previously appointed UK-based Executive 
Directors agreed to reduce their pension allowance from 30% of base 
salary to 20% by the end of 2022, without compensation. 

We recognise recent governance and remuneration statements from 
major institutions to the effect that companies are expected to develop 
a credible plan to align incumbent directors’ pension contribution rates 
with the majority of the wider UK workforce by the end of 2022. The 
Committee has been thinking carefully about this issue, particularly in 
the context of the variety of legacy pension plans in operation and the 
tiered structure of pension contributions throughout the Company which 
I described last year. This matter is under active review, and we shall 
incorporate our longer-term pension proposals as part of our consultation 
for the Directors’ Remuneration Policy binding vote in 2021.

Annual salary review
Against the background of the pandemic and its impact on wider 
society and the economies of the territories where National Grid 
operates, the Committee agreed that, whilst most managers and all 
those covered by trade union agreements would receive increases, it 
would exercise restraint and not award annual salary increases to the 
Group Executive Committee members at this time. The Committee 
however felt that an exception should be made in respect of Andy Agg, 
the CFO. Andy was appointed to his role in January 2019 and, as we 
have done for other appointments, his starting salary was set 
significantly below the assessed market rate for the job with the publicly 
stated intention to increase his salary, subject to his performance and 
progression in the role, toward the assessed market rate. In line with this 
plan Andy would have received a salary increase of 9% from 1 June 2020. 
However, in the context of the other senior executives not receiving a 
salary increase this year, the Committee decided to restrict Andy’s 
increase to 6.5%. In approving this increase, the Committee considered 
that Andy had made a very good contribution to the Group in his first full 
year as CFO, with a particular focus on strengthening his senior financial 
team as well as focusing on the financial preparations for RIIO-2. The 
Committee will again review Andy’s salary next year and may, as 
previously, award him an increase in excess of other senior executives, 
subject to continuing good performance, to bring his salary in line with 
the market rate.

The Remuneration Committee will continue to consider the current and 
potential impact of COVID-19 on the Company and its stakeholders in 
determining if and when any salary increases are awarded. Consistent 
with this decision, there will be no increases in fees for the Board 
Chairman or other Non-executive Directors at this time.

I would also like to note and thank John Pettigrew and Andy Agg for 
their generous donations of £50,000 and £20,000, respectively, to the 
Prince’s Trust to support the Trust’s work with young people giving them 
a lifeline and increased social mobility despite the challenges created 
by the COVID-19 pandemic. The £20,000 donation from Andy Agg 
represents some 50% of the salary increase he will receive for 2020.

Leaving arrangements for Dean Seavers
Dean Seavers, Executive Director, US, stepped down for personal 
reasons from the Board on 5 November 2019. His employment with 
National Grid subsequently terminated on 31 December 2019, following 
a handover period with his successor as President of National Grid’s US 
business. The Committee concluded that ‘good leaver’ remuneration 
provisions should apply under our Directors’ Remuneration Policy. 
Details of his leaving arrangements are provided on page 102.

The Board decided that this position will no longer sit on the Main Board. 
Badar Khan was appointed Interim President of the US Business and 
then was made permanent in this role from 1 April 2020.

Pension
Under the new Policy approved last year, any new UK-based 
Executive Directors will receive a pension contribution/allowance of 
up to 20% of base salary (reduced from 30% previously). To further align 
with the evolving shareholder expectations and market practice, the 
Committee decided that, from November 2019 onwards, any new 
UK-based Executive Directors will receive a pension contribution/
allowance of up to 12% of base salary, which is in line with the defined 
contribution rate available to the majority of the UK-based wider 
workforce. The Company has also cascaded this change so that it 
applies to all new UK hires regardless of level. The current average 
pension contribution across the various pension schemes for the wider 
UK workforce has decreased from 18% last year to 17% this year due 
to natural attrition.

What is our remuneration policy seeking to achieve?
Although we have regularly stated our remuneration policy objectives, it 
is important to set out again what we are seeking to achieve in the way 
we structure senior executives’ remuneration. Our policy aim is to ensure 
that how we structure remuneration and how we make decisions on 
annual and long-term reward plans are compatible with and fully support:
•  attracting, motivating and retaining senior executives while not 

over-paying; 

•  ensuring we pay our senior executives in a way that incentivises 
stretching financial and operational performance, within the risk 
appetite set by the Board;

•  being fully aligned to the way National Grid earns its returns for 

shareholders; and 

•  actively supporting our strategy, ethics, values and contribution to 

society in the territories where we operate.

In addition, in order to ensure internal alignment and common purpose, 
we apply the same broad architecture to the remuneration of our senior 
management team below the Executive Directors. 

The key components of our approach are:

1.   Significant weighting towards long-term value creation 

and alignment with shareholder interests

Nearly three quarters of John Pettigrew’s variable pay opportunity is 
represented by the LTPP. We continue to put a much higher weight on 
this element compared with the APP because National Grid is a 
long-term business with long-life assets. We want to make sure 
investment decisions are made, and operating efficiencies achieved, 
against this background. Moreover, for Executive Directors, some 85% 
of their variable pay opportunity (both annual and long-term) is delivered 
in National Grid’s shares. Consistent with our approach for aligning 
executive interests to the long term, LTPP awards have a three-year 
performance period and a further two-year post-vesting holding period. 
Our LTPP measures for 2020 will continue to be fully aligned with 
long-term value creation and shareholder interests. Figure 1 below 
illustrates how performance measures are structured for 2019 and 2020 
LTPP awards, taking account of the impact of the transition from RIIO-1 
to RIIO-2.

2.   We require senior executives to maintain very high 

shareholdings in National Grid

As CEO, John Pettigrew has to hold at least five times his pre-tax salary 
in National Grid’s shares, which is equivalent to around nine times his 
post-tax salary. Other UK-based Executive Directors must hold at least 
four times their pre-tax salary in National Grid’s shares (equivalent to 
around seven times their post-tax salary). This requirement ensures that 

89

National Grid plc Annual Report and Accounts 2019/20

Corporate Governance

Directors’ Remuneration Report continued

executives necessarily have a longer-term view in their decision-making, 
are rewarded for achieving success progressively over the long term, 
and have interests aligned to our private and institutional shareholders 
– gaining if the share price increases, and sharing in the consequences 
of share price falls. Moreover, we believe our senior management, not 
just Executive Directors, should view the dividends paid on shares they 
earn as part of their overall remuneration arising from National Grid, 
rather than focusing on the annual capital value. An important 
characteristic of our high shareholding requirement is that a newly 
appointed Executive Director who owns no National Grid shares should 
expect to take some six to seven years (assuming target payout levels) to 
have earned the minimum shareholding requirement and will be unable 
to sell shares (other than to pay income tax arising on vesting) prior to 
that point. Our post-employment shareholding requirement further 
enhances the alignment of interests between executives and 
shareholders. Our current post-employment shareholding policy requires 
Executive Directors to hold 200% of salary for two years. We have noted 
recent governance developments and shareholder expectations that the 
post-employment shareholding requirement should be at the same level 
as the in-employment shareholding requirement, although balanced 
against that our in-employment shareholding requirement is at the top 
end of market practice. We will review this matter as part of our 
consultation for the Directors’ Remuneration Policy vote in 2021.

3.   Achievement of short-term (APP) and long-term (LTPP) 
incentive opportunities is linked to National Grid’s 
performance

A key principle of our remuneration policy, and how it operates, is that 
reward should be aligned to the financial and operational performance 
of the Company and to shareholder interests. As set out in the Strategic 
Report, a number of our financial KPIs directly align to our APP and 
LTPP rewards. In addition, non-financial KPIs and wider business 

performance (for example, safety and environmental performance) 
are also taken into account, and discretion applied if appropriate, 
when determining an executive’s performance against their individual 
objectives and in confirming the overall final payouts (APP) and/or 
vesting outcomes (LTPP). Our approach, illustrating how variable pay 
is linked to performance, is illustrated below in Figure 2.

4.   Discretion and independent judgement is applied. 

Achievement of short-term (APP) and long-term (LTPP) 
incentive opportunities is linked to National Grid’s 
performance

As I stated last year, as a committee we consider whether to apply 
discretion when assessing remuneration outcomes for Executive 
Directors. Before approving any payments under either the APP or LTPP, 
we reflect with great care first on both the underlying financial and wider 
business performance of the Company; we then assess the wider 
performance of the Company in terms of its societal contribution, its 
relations with regulators, and its overall reputational standing with 
stakeholders. We also undertake a careful appraisal of the performance 
of each Executive Director and members of the Executive Committee 
against their individual objectives set for them at the start of the year and 
their demonstration of leadership qualities and our values. Whilst the 
underlying financial performance of the Company is a material factor 
in our assessments, the Committee has shown and will continue to 
demonstrate a willingness to apply discretion to adjust final payments 
in light of all factors considered relevant by the Committee.

In addition to applying discretion to final payment levels, the Committee 
considers whether there might be any basis for applying malus and/or 
clawback to awards made and/or payments already received by an 
individual where subsequent events or factors justify taking such steps.

Fair and Appropriate
When making remuneration decisions for the Executive Directors and 
other senior leaders, the Remuneration Committee takes account of 
the remuneration arrangements and outcomes for the wider workforce, 
statistical information, such as the CEO pay ratio and gender pay gap 
data, employee views on executive pay as part of our employee voice 
process, and our Company values. Last year, we voluntarily reported our 
CEO pay ratio one year early, with a median ratio of 76:1 for UK-based 
employees. This year, the median ratio for UK-based employees is 86:1. 
Our Group-wide median ratio was 48:1 last year and 53:1 this year. The 
increases in both ratios are largely due to the increase in LTPP vesting. 
The lower Group-wide ratio reflects the higher general level of wages in 
the US compared with the UK, and especially in the regions of the US 
where the Company operates. It is also important to recognise that 
around three quarters of our employees are in the US. In terms of UK 
gender pay gap, there has been an improvement from the median of 
4.4% last year to 2.6% this year.

Changes to the Committee membership
Nora Mead Brownell resigned from the Board on 8 April 2019. 
Jonathan Silver joined the Board and was appointed to the Committee 
on 16 May 2019.

Developments for 2020/21
Looking ahead, and as already mentioned, the Committee’s work will 
be dominated by considering the impact of RIIO-2 on our remuneration 
structure. In addition, we will also be mindful of the evolving practice on 

90

executive pension levels (where we have already taken steps to align 
different employee levels). We will also be considering how best to build 
into our remuneration arrangements consideration of key non-financial 
objectives, such as environmental issues and the Company’s 
performance in reducing emissions and enabling the wider societal 
evolution towards new and renewable energy sources and networks. 
In our review of policy for 2021, we will consult on all of these matters 
during the year ahead. 

Conclusion
The Committee has carefully reviewed the performance of the senior 
executive team during the year and the prior three years to assess 
whether the level of APP and LTPP payments/vesting were aligned with 
the Company’s performance over the period and concluded that the 
arrangements set out in this Remuneration Report were a fair reflection 
of their individual and collective performance. Accordingly, on behalf of 
the Committee, I commend this Directors’ Remuneration Report to you 
and ask for your support at the Annual General Meeting.

Notes:
1.   Dean Seavers stepped down from the Board for personal reasons on 5 November 2019 and left the Company on 31 December 2019. In the above table, the maximum if variable pay vested 

in full relates to the period 1 April to 31 December 2019 and includes base salary, benefits in kind, pension, 2019/20 APP and 2017 LTPP vesting.

2.   For each UK-based Executive Director the share price has increased between grant date of the LTPP awards in 2017 and the estimated share price value at vesting, being the three months’ 
average preceding 31 March 2020. Comparing the share price at grant of 973.80p for Andy Agg, John Pettigrew and Nicola Shaw versus the estimated average share price for the period 
1 January 2020 to 31 March 2020 (978.75p), there is an increase of 4.95p (0.5%) per share. Andy Agg received a second 2017 LTPP tranche and comparing the share price at grant of 
941.50 versus the estimated average share price for the period 1 January 2020 to 31 March 2020 (978.75p), there is an increase of 37.25p (4.0%) per share. This results in an estimated 
increase in value (net of dividend equivalents) of £10,554 in total for Andy Agg, £15,107 for John Pettigrew, and £7,063 for Nicola Shaw. For the former US-based Executive Director, Dean 
Seavers, the ADS price has decreased between grant date and the estimated average ADS price for the period 1 January 2020 to 31 March 2020 ($62.48). Comparing the ADS price 
at grant of $63.94 versus the estimated ADS price of $62.48 there is a reduction of $1.46 (2.0%) per ADS. This results in an estimated reduction in value (net of dividend equivalents) of 
$56,810 for Dean Seavers. Overall, the percentage growth in value over the three-year period due to dividend income per share/ADS is at least 11%, and this will increase further subject to 
a final dividend to be included on the vesting date.

Directors’ Remuneration Report continued

Directors’ remuneration policy – approved by shareholders in 2019

Key aspects of the current Director’s remuneration policy, along with elements particularly applicable to the 2019/20 financial year, are shown on 
pages 92 – 95 for ease of reference only. The current policy was approved for three years from the date of the 2019 AGM, held on 29 July 2019. 
A shareholder vote on the remuneration policy is not required in 2020. A copy of the full remuneration policy is available within the 2018/19 Annual 
Report and Accounts on the Company’s investor website (investors.nationalgrid.com).

From time to time, the Committee may consider it appropriate to apply some judgement and discretion in respect of the approved policy. 
This is highlighted where relevant in the policy, and the use of discretion will always be in the spirit of the approved policy.

Our peer group
The Committee reviews its remuneration policy against appropriate peer groups annually to make sure we remain competitive in the relevant 
markets. The primary focus for reward market comparisons is the FTSE 11-40 for UK-based Executive Directors and general industry and 
energy services companies with similar levels of revenue for US-based Executive Directors. These peer groups are considered appropriate 
for a large, complex, international and predominantly regulated business.

The Committee reviews annually the overall appropriateness and relevance of the remuneration policy and whether any changes should be put to 
shareholders. Decisions on the levels of measures and targets for performance related pay (APP and LTPP) and payouts are made taking account 
of overall financial and business performance. A member of the Audit Committee is required to be a member of the Committee and this ensures 
the Committee receives knowledgeable input on setting financial measures and assessing outturns including any adjustments and judgements 
considered by the Audit Committee. The Committee also works closely with the Nominations Committee in respect of pay and conditions of newly

Maximum levels

Salaries are generally reviewed annually and are targeted 
broadly at mid-market of our peer group. However a 
number of other factors are also taken into account:
•  business performance and individual contribution;
•  the individual’s skills and experience;
•  scope of the role, including any changes in responsibility; and
•  market data, including base pay and total remuneration 

opportunity in the relevant comparator group.

No prescribed maximum annual 
increase, although increases are 
generally aligned to salary increases 
received by other Company 
employees and to market movement. 
Increases in excess of this may be 
made at the Committee’s discretion 
in circumstances such as a 
significant change in responsibility, 
progression if more recently 
appointed in the role and broad 
alignment to mid-market.

None of the current Executive Directors are active 
members of a DB plan. 

Operation

Maximum levels

Externally hired Executive Directors will participate in 
a Defined Contribution (DC) arrangement. UK-based 
Executive Directors may alternatively choose to 
receive cash in lieu.

In cases of internal promotion to the Board, the 
Company will recognise legacy Defined Benefit (DB) 
pension arrangements of existing employees in both 
the UK and US where these have been provided 
under an existing arrangement.

In line with market practice, pensionable pay for 
UK-based Executive Directors includes basic salary 
only and for US-based Executive Directors it 
includes basic salary and APP award.

UK DC: annual contributions for new 
appointments of up to 20% of basic salary. 
Existing Executive Directors may receive annual 
contributions of up to 30% of basic salary. 
Executive Directors may take a full or partial 
cash supplement in lieu.

Life assurance of four times basic salary and a 
dependant’s pension of one third of basic salary 
is provided. Executives with HMRC pension 
protection may be offered lump sum life assurance 
only, equal to four times basic salary.

UK DB: a pension generally payable from age 60 
or 63. DB benefits are subject to capped increases 
in pensionable salary. No enhancement is provided 
on promotion to the Board. Funded DB benefits 
are subject to HMRC maximum allowances and 
limits. On death in service, a lump sum of four 
times pensionable salary and dependant’s 
pension of two-thirds of the Executive Directors’ 
pension is provided. DB pension plans were 
closed to new members by April 2006.

US DC: annual contributions of up to 9% of basic 
salary plus APP award with additional 401(k) plan 
match of up to 4%.

US DB: an Executive Supplemental Retirement 
Plan provides for an unreduced pension benefit at 
age 62 (this plan is closed to new participants from 
1 January 2015). For retirements at age 62 with 
35 years of service, the pension benefit would be 
approximately two thirds of pensionable salary. 
DB final average pay plan is subject to capped 
increases in pensionable pay. Upon death in 
service, the spouse would receive 50% of the 
pension benefit (100% if the participant died 
while an active employee after the age of 55).

Pension footnote: The Remuneration Committee agreed in November 2019 (i.e. after the July 2019 AGM Policy vote) that newly appointed Executive Directors will receive annual 
contributions of up to 12% of basic salary for the DC pension scheme, or cash supplement in lieu.

Annual Performance Plan (APP)

including the delivery of annual individual objectives and demonstration of our Company leadership qualities and values.

Operation

Maximum levels

Performance metrics, weighting 
and time period applicable

The APP comprises reward for achievement against 
financial measures and achievement against 
individual objectives.

Financial performance measures and targets are 
normally agreed at the start of each financial year 
and are aligned with strategic business priorities. 
Targets are set with reference to the budget. 
Individual objectives and associated targets are 
normally agreed also at the start of the year.

APP awards are paid in June.

50% of the APP award is paid in shares, which 
(after any sales to pay-associated income tax) must 
be retained until the shareholding requirement is 
met, and in any event for two years after receipt.

Awards are subject to malus and clawback 
provisions as set out in the paragraph overleaf.

The maximum award is 125% of basic salary 
in respect of a financial year.

At least 50% of the APP is based on performance 
against financial measures.

The Committee may use its discretion to set 
financial measures that it considers appropriate 
in each financial year and has the flexibility to 
modify the amount payable, to reflect wider 
financial and business performance, 
demonstration of leadership qualities and our 
values, or to take account of a significant event.

The payout levels at threshold, target and 
stretch performance levels are 0%, 50% and 
100%, respectively.

and shareholder interests over the longer term.

Operation

Maximum levels

Performance metrics, weighting and time period applicable

The maximum award for the 
CEO is 350% of salary and it 
is 300% of salary for the other 
Executive Directors based on 
salary at the time of the award.

Awards of shares may be granted each year, with 
vesting subject to long-term performance conditions.

The performance measures have been chosen as the 
Committee believes they reflect the Executive Directors’ 
creation of long-term value within the business. Targets 
are set for each award with reference to the business plan.

Participants may receive ordinary dividend equivalent 
shares on vested shares, from the time the award was 
made, at the discretion of the Committee.

Participants must retain vested shares (after any sales 
to pay tax) until the shareholding requirement is met, 
and in any event for a further two years after vesting.

Awards are subject to malus and clawback provisions 
as set out in the paragraph below.

The performance measures are Group Value Growth and Group 
RoE for all Executive Directors. For awards made in financial year 
2019/20: Group Value Growth measured over three years 
(2019/20, 2020/21 and 2021/22) and Group RoE measured over 
two years (2019/20 and 2020/21) such that Group Value Growth 
represents two thirds and Group RoE represents one third of the 
total vesting outcome.

For awards made in financial year 2020/21: Group Value Growth 
measured over three years (2020/21, 2021/22 and 2022/23) and 
Group RoE measured over one year (2020/21) such that Group 
Value Growth represents five sixths and Group RoE represents 
one sixth of the total vesting outcome.

For awards made in 2016 which will vest in 2019, the 
performance measures and percentage weightings are: Group 
Value Growth (50%) and Group RoE (50%) for the CEO and CFO; 
Group Value Growth (50%), Group RoE (25%) and UK or US RoE 
(25%) for the UK and US Executive Directors respectively.

For awards made in 2017 and 2018 which will vest in 2020 and 
2021 respectively, the performance measures were Group Value 
Growth and Group RoE, equally weighted, for all Executive Directors.

All awards have a three-year performance period.

For each performance measure, threshold performance will 
trigger only 20% of the award to vest; 100% will vest if maximum 
performance is attained.

Notwithstanding the level of award achieved against the 
performance conditions, the Committee may use its discretion to 
modify the amount vesting to reflect wider financial and business 
performance and take account of a significant event and/or 
compliance with the dividend policy.

Malus and clawback 
The Committee has discretion to determine whether exceptional circumstances exist which justify whether any or all of an award should be forfeited, 
even if already paid. Examples of exceptional circumstances include, but are not limited to, material misstatement, misconduct of the participant, 
a significant environmental, health and safety or customer issue or failure of risk management, and if certain other facts emerge after termination 
of employment. The Committee also has a prescribed process to follow when determining whether and how to apply this discretion.

of similar scale and complexity.

The cost of benefits provided to 
the Chairman is not subject to a 
predetermined maximum since 
the purchase cost will vary from 
year to year.

NED fees (excluding those of the Chairman) are set by 
the Executive Committee in conjunction with the Chairman. 
The Chairman’s fees are set by the Committee.

Fee structure:
•  Chairman fee (all inclusive);
•  basic fee, which differs for UK- and US-based NEDs;
•  Committee chair fee;
•  Committee membership fee; and 
•  Senior Independent Director fee.

No additional fees are paid for membership/chair of the 
Nominations Committee.

Fees are reviewed every year taking into account those 
in companies of similar scale and complexity.

The Chairman is covered by the Company’s private 
medical and personal accident insurance plans, and 
has the use of a car and driver, when required.

NEDs do not participate in incentives, pension or any 
other benefits. However, they are eligible for reimbursement 
for all Company-related travel expenses. In instances 
where these costs are treated by HMRC as taxable 
benefits, the Company also meets the associated tax 
cost to the Non-executive Directors through a PAYE 
settlement agreement with HMRC.

NEDs who also sit on National Grid subsidiary boards may 
receive additional fees related to service on those boards.

Corporate Governance | Directors’ Remuneration Report

Directors’ remuneration policy – approved by shareholders in 2019 continued

In the event of a UK Director’s role becoming redundant, statutory 
compensation would apply and the relevant pension plan rules may 
result in the early payment of an unreduced pension. 

On termination of employment, no APP award would generally be 
payable. However, the Committee has the discretion to deem an 
individual to be a ‘good leaver’, in which case a pro-rata discretionary 
payment could be paid, based on financial performance (as measured at 
the end of the financial year) and the achievement of individual objectives 
during the financial year up to termination. In the UK the discretionary 
payment would generally be paid at the normal time. In the US the 
payment would be made earlier if required for tax compliance purposes, 
in which case the Committee would apply discretion to determine an 
appropriate level of financial performance. Examples of circumstances, 
whilst not exhaustive, which could trigger ‘good leaver’ treatment include 
redundancy, retirement, illness, injury, disability and death. The 
Committee will apply discretion to determine if the pro-rata discretionary 
payment should be made sooner than it would normally be paid, for 
example, in the case of death.

On termination of employment, outstanding awards under the share 
plans will be treated in accordance with the relevant plan rules approved 
by shareholders. Unvested share awards would normally lapse. ‘Good 
leaver’ provisions apply at the Committee’s discretion and in specified 
circumstances. Examples of circumstances, whilst not exhaustive, which 
could trigger ‘good leaver’, include: redundancy, retirement, illness, injury, 
disability and death, where awards will be released to the departing 
Executive Director or, in the case of death, to their estate. Long-term 
share plan awards held by ‘good leavers’ will normally vest subject to 
performance measured at the normal vesting date and will be reduced 
pro-rata for each completed month starting on the date of grant. Such 
awards would vest at the same time as for other participants, apart from 
circumstances in which the award recipient has died, in which case the 
awards vest as soon as practicable (based on a forecast of performance).

At the Committee’s discretion, the Company may also agree other 
payments such as an agreed amount for legal fees associated with the 
departure of the Executive Director and outplacement support.

Service contracts/letters of appointment
In line with our policy, all Executive Directors have service contracts 
which are terminable by either party with 12 months’ notice. 
Non-executive Directors are subject to letters of appointment. 
The Chairman’s appointment is subject to six months’ notice by 
either party; for other Non-executive Directors, notice is one month. 
Both Executive Directors and Non-executive Directors are required 
to be re-elected at each AGM.

Please refer to the full remuneration policy within the 2018/19 
Annual Report and Accounts on the Company’s investor website 
(http://investors.nationalgrid.com) for our remuneration policy on 
Directors’ recruitment, external appointments, total remuneration 
opportunity and corporate and share capital events.

Shareholding requirement – in employment
The requirement of Executive Directors to build up and hold a significant 
value of National Grid shares ensures they share a significant level of risk 
with shareholders and aims to align their interests. Executive Directors 
are required to build up and retain shares in the Company. The level of 
holding required is 500% of salary for the CEO and 400% of salary for 
the other Executive Directors. Unless the shareholding requirement is 
met, Executive Directors will not be permitted to sell shares, other than 
to pay income tax liabilities on shares just vested or in exceptional 
circumstances approved by the Remuneration Committee.

Shareholding requirement – post employment
The requirement of Executive Directors to continue to hold National Grid 
shares after leaving ensures they continue to share a risk with 
shareholders and maintain alignment with shareholders’ interests. 
Executive Directors will be required to hold 200% of base salary 
calculated at their leave date, or maintain their actual holding percentage 
if lower, expressed as a number of shares and held for a period of two 
years. This calculation excludes the value of any awards not yet vested 
for ‘good leavers’ that will vest according to the normal schedule and 
which in any event must be held for a two-year period. The calculation 
will include recently vested LTPP awards or APP awards paid as shares 
which are subject to respective two-year holding periods, even after 
employment. Unless the post-employment shareholding requirement is 
met, Executive Directors will not be permitted to sell shares, other than 
to pay income tax liabilities on shares just vested or in exceptional 
circumstances approved by the Remuneration Committee.

Consideration of remuneration policy elsewhere in the Company
Our remuneration policy is generally aligned to the policies for our 
non-unionised workforce. All employees are entitled to base salary, 
benefits and pension contributions. In setting the remuneration policy 
the Committee considers the remuneration packages offered to 
employees across the Company. As a point of principle, salaries, 
benefits, pensions and other elements of remuneration are assessed 
regularly to ensure they remain competitive in the markets in which we 
operate. In undertaking such assessment our aim is to be at mid-market 
for all job bands, including those subject to union negotiation. As would 
be expected, we have differences in pay and benefits across the 
business which reflect specific accountabilities and labour markets. 
There are elements of remuneration policy which apply to all, for 
example, flexible benefits and share plans.

When considering annual salary increases, the Committee reviews the 
proposals for salary increases for the employee population generally, 
as it does for any other changes to remuneration being considered.

All employees are eligible for an annual performance-based award. 
Eligibility and the maximum opportunity available is based on market 
practice for incentives for the employee’s job band. In addition, around 
400 senior management employees are awarded LTPPs annually, which 
include the same performance measures as those for Executive Directors.

The Company has a number of all-employee share plans that provide 
employees with the opportunity to become, and to think like, a 
shareholder. These plans include Sharesave and the Share Incentive 
Plan (SIP) in the UK and the 401(k) and 423(b) plans in the US. Further 
information is provided on page 92.

The Company issues an employee engagement survey each year, 
which includes remuneration as a topic. It does not specifically invite 
employees to comment on the Directors’ remuneration policy but any 
comments made by employees are noted. The Board also regularly 
engages with employees on a variety of topics, including remuneration.

Policy on payment for loss of office
The contracts contain provisions for payment in lieu of notice, at the sole 
and absolute discretion of the Company. Such contractual payments are 
limited to payment of salary only for the remainder of the notice period. 
In the UK such payments would be phased on a monthly basis, over a 
period not greater than 12 months, and the Executive Director would be 
expected to mitigate any losses where employment is taken up during 
the notice period. In the US, for tax compliance purposes, the policy is 
to make any payment in lieu of notice as soon as reasonably practicable, 
and in any event within two and a half months of the later of 31 December 
and 31 March immediately following the notice date.

Notes:
Dean Seavers: 2019/20 fixed pay components in the table above are for the period he served as a Director during the year, from 1 April to 5 November 2019; 2019/20 variable pay 
components in the table above are for the period during which he was employed, from 1 April to 31 December 2019.
Andy Agg: 2018/19 figures in the table above are for the period he served as a Director during the year, from 1 January to 31 March 2019.
Salary: Base salaries were last increased on 1 June 2019 other than for Andy Agg, who was not eligible to receive a salary increase due to being appointed CFO on 1 January 2019. 
Benefits in kind: Benefits in kind (BIK) include private medical insurance, life assurance and, for UK-based Executive Directors, either a fully expensed car or a cash alternative to a car 
and the use of a car and a driver when required and which, for John Pettigrew, amounted to approximately £86,000 for 2019/20 (and approximately £75,000 for 2018/19). A Sharesave 
option award was granted to John Pettigrew on 27 December 2019 and the benefit (approximately £8,000) of this award is included. There were no Sharesave options granted to any 
of the other Executive Directors during 2019/20.
APP: John Pettigrew will donate 20% of his 2019/20 APP (net of tax) to a charity involved in the emergency COVID-19 response in our US service territories. Dean Seavers received a nil 
payout for the individual portion of the APP. Consistent with Company policy for all colleagues not covered by a trade union agreement, this results in a nil payout overall. Information 
relating to amounts paid for the loss of office can be found on page 102.
LTPP: The 2017 LTPP is due to vest in July 2020. The average share price over the three months from 1 January 2020 to 31 March 2020 of 978.75p ($62.48 per ADS) has been applied 
and estimated dividend equivalents are included. The 2018/19 LTPP figures have been restated because last year they were estimated using the average share price (January–March 
2019) and they now include the actual share price on vesting at 1 July 2019 and all dividend equivalent shares. Due to a higher share price at vesting of 842.10p versus the estimate of 
837.34p (and the additional dividend equivalent shares added for the dividend with a record date of 31 May 2019 with a dividend rate of 31.26p per share), the actual value at vesting was 
£770, £89,005 and £37,991 higher than for the estimate last year for Andy Agg, John Pettigrew, and Nicola Shaw, respectively. Despite a lower ADS price at vesting of $52.736 versus 
the estimate of $54.73, the actual value at vesting was £539 higher than for the estimate last year for Dean Seavers. This is because the change in ADS price was offset by the additional 
dividend equivalent ADSs for the dividend with a record date of 31 May 2019 with a dividend rate of $2.0256 per ADS. 
Impact of share price change: The impact of share price appreciation/depreciation, comparing share/ADS prices at grant versus the estimated share/ADS prices upon vesting is set 
out in the notes to the 2017 LTPP (vesting) table on page 101.
Exchange rate: $1.2868:£1.

AUDITED

Total pension benefits
Andy Agg, John Pettigrew and Nicola Shaw received a cash allowance in lieu of participation in a pension arrangement. Dean Seavers 
participated in a defined contribution pension arrangement in the US until he left the business at 31 December 2019. There are no additional 
benefits on early retirement. The values of these benefits, received during this year, are shown in the single total figure of remuneration table.

John Pettigrew has, in addition, accrued defined benefit (DB) entitlements. He opted out of the DB scheme on 31 March 2016 with a deferred 
pension and lump sum payable at his normal retirement date of 26 October 2031. At 31 March 2020, John Pettigrew’s accrued DB pension was 
£165,031 per annum and his accrued lump sum was £495,092. No additional DB entitlements have been earned over the financial year, other 
than an increase for price inflation due under the pension scheme rules and legislation. Under the terms of the pension scheme, if he satisfies 
the ill health requirements, or he is made redundant, a pension may be payable earlier than his normal retirement date. A lump sum death in 
service benefit is also provided in respect of these DB entitlements.

Annual Performance Plan (APP)
Performance against targets for APP 2019/20 
APP awards are earned by reference to the financial year and this year will be paid in July 2020. Financial measures determine 70% of the APP, 
and individual objectives determine 30% of the APP.

Payment of the APP award is made in shares (50% of the award) and cash (50%). Shares (after any sales to pay income tax) must be retained 
until the shareholding requirement is met, and in any event for two years after receipt. 

For financial measures, threshold, target and stretch performance levels are predetermined by the Committee and pay out at 0%, 50% and 
100% of the maximum potential for each part and on a straight-line basis in between threshold and stretch performance. 

Target and stretch performance levels for the individual objectives are also predetermined by the Committee, and an assessment of the 
performance relative to the target and stretch performance levels is made at the end of the performance year on each objective.

The outcomes of APP awards earned for financial performance are summarised in the table immediately below. Performance against individual

UK financial measures: Technical adjustments have been made reducing the underlying UK Operating Profit target to reflect the net effect of certain actuarial assumptions on 
pensions (£5m reduction) and normalisation to reflect the impact of RPI (£11m reduction) and reducing the UK Value Added target by £14m to ensure consistency of accounting 
treatment.
US financial measures: Technical adjustments have been made reducing the underlying US Operating Profit target by £70m to reflect the net effect of currency adjustments, 
deferrable storm costs and certain actuarial assumptions on pensions. Technical adjustments have been made reducing the US Value Added target by £33m to reflect the net effect 
of currency adjustments and the impact of deferred tax movements.
Individual Objectives: For 2019/20 the Committee has applied discretion to cap the payout for overall individual achievement against individual objectives at the lower of target and 
actual achievement to reflect restraint in the context of COVID-19 and to be consistent with decisions made for the wider managerial population. This discretion is not incorporated above.

Individual Objectives
The individual objectives of the Executive Directors when taken together were designed to deliver against each of our 2019/20 business priorities. 
The Committee adopts a two-stage process to agree individual objectives. First it reviews and provides feedback on the objectives including 
consideration of the weighting based on business criticality of the objective and then, at a second meeting, it completes a final review and approves 
the objectives. At the end of the year an overall assessment is made which takes account of the weighting and achievement of the respective 
individual objectives for each Director and the degree to which each element of the objective was met against specific target and stretch targets. 
As with the financial measures, the achievement of ‘stretch’ performance and ‘target’ performance overall results in 100% and 50% respectively 
of the maximum payout. 

For 2019/20 the Committee has applied discretion to cap the payout for overall achievement against individual objectives at the lower of target and 
actual achievement to reflect restraint in the context of COVID-19 and to be consistent with decisions made for the wider managerial population. This 
discretion is not incorporated in the percentage outcomes below. 

Andy Agg 

Individual objective & performance commentary

Drive operating efficiency of the business and finance function
•  Delivered targeted UK cost efficiencies of £50 million and on track to deliver a further £100 million in 2020/21

•  Enabled positive outcome on Massachusetts Electric (MECO) rate case
•  Maximum not awarded due to regulatory outcomes not fully at stretch levels

Support in updated investor proposition review and Total Societal Impact initiative 
•  Established and gained agreement from the Board for an appropriate investor proposition
•  Completed sale of minority stake in Cadent in line with agreed timing
•  More opportunities remain in identifying additional financeable growth opportunities for sustained outperformance

Drive the talent agenda
•  Made positive progress on development and succession planning deeper in the Finance function

aspirations

Summary

Andy had a good year and has firmly established himself in the CFO role. He provided good leadership on the investment 
proposition, started to transform the Finance function and strengthened talent capabilities. Outside of his core objectives he 
has also made strong contributions in articulating National Grid’s contributions as a corporate entity in the State Ownership 
debate, introducing GAAP reporting. More work is needed in driving the talent agenda in the US and progressing additional 
risk and control measures.

John Pettigrew

Individual objective & performance commentary

Optimise regulatory/government agreements and relationships 
•  Led a successful response to the near simultaneous tripping of two large power stations in August 2019 leading to power 
outages in various parts of England and Wales, including re-establishing power within the timeframes required by Ofgem, 
and engaging with Ofgem in the investigation and learnings reviews which confirmed that the outage was not caused by 
National Grid infrastructure

on certain issues

•  Achieved a successful outcome for the Hinkley-Seabank project in the UK and the MECO rate case in Massachusetts

administrations in Massachusetts and Rhode Island, though there is more work to be done in New York to rebuild our 
reputation following the issues arising from the downstate New York Gas moratorium

Develop external National Grid value proposition 
•  Established and gained agreement from the Board for an appropriate investor proposition
•  Additionally, established and gained agreement from the Board for a new framework for defining National Grid’s Total 

Societal Impact to support our aspirations as we continue to emphasise the importance of being a purpose-led organisation

Continue work to ensure National Grid is well placed for growth and innovation
•  Continued to build an effective platform for growth through National Grid Ventures, particularly with the purchase of 

renewables developer Geronimo Energy

•  Delivered the digital strategy in both the UK and US

AUDITED

LTPP performance
The LTPP value included in the 2019/20 single total figure relates to anticipated vesting in July 2020 of the conditional LTPP awards granted 
in 2017.

2017 LTPP
The 2017 award is determined by performance over the three years ended 31 March 2020 of Group RoE (50% weighting) and Group Value 
Growth (50% weighting), which is expected to vest on 27 July 2020. The financial components and weightings for this year’s vesting, i.e., the 
2017 LTPP awards, are the same for all Executive Directors. The Group Value Growth outturn includes an amount to reflect the value added 
from the sale of the residual interest in the UK Gas Distribution business and to adjust for revised timing of UK tax payments in 2019/20.

The Committee has decided not to apply any discretion following consideration of wider financial performance during the 3-year performance period.

Andy Agg: Andy Agg’s award of 49,080 shares was granted in two tranches. The first tranche of 21,996 shares was granted on 28 June 2017 followed by a second tranche of 
27,084 shares granted on 24 July 2017. Both awards are subject to the same performance conditions, performance period and vesting percentage/dividend equivalents estimates. 
Dean Seavers: Dean Seavers’ original award of 49,294 ADSs has been prorated to 41,078 ADSs on the basis of completed months employed between the grant date and 
31 December 2019.
Impact of share price change: The impact of share price change for the 2017 LTPP, comparing share price at grant versus the average share price for the period 1 January 2020 to 
31 March 2020 of 978.75p ($62.48 per ADS), for each Executive Director: for John Pettigrew and Nicola Shaw the share price at grant was 973.80p resulting in an increase per share of 
4.95p (0.5%) and this results in an estimated increase in value (including dividend equivalents) of £15,107 for John Pettigrew and £7,063 for Nicola Shaw; Andy Agg received his 2017 
LTPP award in two tranches and the share prices at grant for his awards were 973.80p and 941.50p resulting in increases per share of 4.95p (0.5%) and 37.25p (4%) respectively and this 
results in estimated increases in value (including dividend equivalents) of £1,028 and £9,526 respectively; for Dean Seavers the ADS price at grant was $63.94 resulting in a decrease per 
ADS of $1.46 (2%) and this results in an estimated reduction in value (including dividend equivalents) of $56,810. The impact of share price change is not included in the expected 
amounts to vest shown in the above table.

Leaving arrangements for Dean Seavers
Dean Seavers stepped down from the Board for personal reasons on 5 November 2019 and remained employed by the Company until 
31 December 2019 to support a smooth leadership transition and handover.

Mr Seavers’ remuneration in relation to his fixed pay for the period 1 April 2019 to 5 November 2019, his 2019/20 APP and his 2017 LTPP is 
disclosed in the Single Total Figure of Remuneration table on page 96. For the period from 6 November 2019 to 31 March 2020, Mr Seavers 
received remuneration totalling £1.1 million which predominantly includes his fixed pay (salary, benefits and pension) until 31 December 2019, his 
pay in lieu of notice of approximately £732,000 and his accrued holiday of approximately £133,000. All payments are in accordance with his 
service agreement and the Directors’ Remuneration Policy and subject to applicable tax withholdings. As part of Mr Seavers’ agreed leaver 
arrangements the Company will fund limited costs for security arrangements until 31 December 2020. These costs are expected to be no more 
than $35,000.

The Committee agreed to grant good leaver treatment for Mr Seavers’ outstanding LTPP awards given his overall long-term strong performance 
and contribution to the business. Mr Seavers’ outstanding ADS awards under the 2018 and 2019 Long Term Performance Plan (LTPP) will be 
prorated for completed months held since the award date until 31 December 2019, as set out in the table below. These awards will vest at the 
same time as other participants, subject to performance measured at the vesting date and any discretion the Committee may decide to 
exercise at the time of vesting, in line with our Directors’ Remuneration Policy. These shares will be subject to the two-year post-vesting holding 
requirement and post-employment shareholding requirement, if not already met.

Corporate Governance | Directors’ Remuneration Report

Statement of implementation of remuneration policy in 2019/20 continued

Payments to past Directors and post-employment shareholdings
There have been no payments to any other past Director during 2019/20. Past Directors are required to continue to hold their shares/ADSs with the 
Company’s third-party share scheme administrator in order to audit compliance; at 31 March 2020 Andrew Bonfield and Dean Seavers have each 
continued to meet their post-employment share-holding requirements. 

Shareholder dilution 
Where shares may be issued or treasury shares reissued to satisfy incentives, the aggregate dilution resulting from executive share-based incentives 
will not exceed 5% in any 10-year period. Dilution resulting from all incentives, including all-employee incentives, will not exceed 10% in any 10-year 
period. The Committee reviews dilution against these limits regularly and under these limits the Company, as at 31 March 2020, had headroom of 
3.89% and 7.86% respectively.

AUDITED

Statement of Directors’ shareholdings and share interests 
The Executive Directors are required to build up and hold a shareholding from vested share plan awards. The following table shows how each 
Executive Director complies with the shareholding requirement and also the number of shares owned by the Non-executive Directors, including 
connected persons. The shareholding is as at 31 March 2020 and the salary used to calculate the value of the shareholding is the gross annual 
salary as at 31 March 2020.

John Pettigrew has met his shareholding requirement. As Andy Agg and Nicola Shaw are still relatively new in post and to the Company, 
respectively, they have not yet met their requirement, but each are expected to do so in 2023 assuming on-target performance/vesting 
outturns. They will not be allowed to sell shares, except for covering associated tax liabilities, until this requirement is met. Dean Seavers had 
met his shareholding requirement before he stepped down from the Board. Non-executive Directors do not have a shareholding 
requirement. 

A further 50 shares have been purchased between April and June on behalf of each of Andy Agg, John Pettigrew and Nicola Shaw via the 
Share Incentive Plan (an HMRC tax-advantaged all-employee share plan), thereby increasing their beneficial interests. There have been no other 
changes in Directors’ shareholdings between 1 April 2020 and 17 June 2020.

The normal vesting dates for the conditional share awards subject to performance conditions are 1 July 2020, 1 July 2021 and 1 July 2022 
for the 2017 LTPP, 2018 LTPP and 2019 LTPP respectively.

Relative importance of spend on pay
The chart below shows the relative importance of spend on pay compared with other costs and disbursements (dividends, tax, net interest and 
capital expenditure). Given the capital-intensive nature of our business and the scale of our operations, these costs were chosen as the most relevant 
for comparison purposes. All amounts exclude exceptional items and remeasurements.

Performance graph
This chart shows National Grid plc’s 10-year annual Total Shareholder Return (TSR) performance against the FTSE 100 Index since 31 March 2010 
and illustrates the growth in value of a notional £100 holding invested in National Grid on 31 March 2010, compared with the same invested in 
the FTSE 100 index. The FTSE 100 Index has been chosen because it is the widely recognised performance benchmark for large companies in 
the UK. The TSR level shown at 31 March each year is the average of the closing daily TSR levels for the 30-day period up to and including that date. 
It assumes dividends are reinvested.

Notes:
Single total figure 2019/20: The figure for 2019/20 for John Pettigrew is explained in the single total figure of remuneration table for Executive Directors.
Single total figure 2018/19: The figure for 2018/19 has been restated to reflect actual share price at 1 July 2019, consistent with comparative figures shown in this year’s single total figure 
of remuneration table.
2014 LTPP: The 2016/17 single total figure of remuneration includes both the 2013 LTPP award and the 2014 LTPP award due to a change in the vesting period of three years to four years 
between the 2013 LTPP and 2014 LTPP.
PSP/LTPP plans: Prior to 2014, LTPP awards were made under a different LTI framework which incorporated a four-year performance period for the RoE element of the awards. The last 
award under this framework was made in 2013 and was fully vested in 2017. Awards made from 2014 are subject to a three-year performance period. The first of these awards vested in 2017.

Percentage change in CEO’s remuneration 
The table below shows how the percentage change in the CEO’s salary, benefits and APP between 2018/19 and 2019/20 compares with the 
percentage change in the average of each of those components of remuneration for non-union employees in the UK and the US. The Committee 
views this group as the most appropriate comparator group, as this group excludes employees represented by trade unions whose pay and benefits 
are negotiated with each individual union, each with their own pay structure.

Notes:
Non-union employees: The population is not a constant comparator group due to external hires, promotions and attrition between years. Calculating the APP change comparing employees 
that were employed throughout the period results in a 0.35% change. The result is impacted also by the proportion of new employees that have not accrued a ‘full year’ of APP payout and 
changes in business results which this year drive in particular a lower APP payout for our US business versus last year. 
Pay data for US employees have been converted at $1.2868:£1.

CEO pay ratio 
We have disclosed our CEO pay ratios comparing the CEO single total figure of remuneration to the equivalent pay for the lower quartile, median and 
upper quartile UK employees (calculated on a full-time equivalent basis) in accordance with the Companies (Miscellaneous Reporting) Regulations 
2018 (as amended), which formally apply to National Grid from this reporting year, 2019/20. We disclosed these ratios on a voluntary basis last year 
for 2018/19.

The comparison with UK employees is specified by the regulations. US employees represent approximately 73% of our total employees. Our median 
pay ratio on a Group-wide basis is 53:1, calculated on the same basis as the UK pay ratios and an exchange rate of $1.2868:£1.

Salaries at 31 March 2020 and estimated performance-based annual payments for 2019/20 have been annualised to reflect full-time equivalents. 
Performance payments have not been further adjusted to compensate where new employees have not completed a full performance year.

The CEO pay ratio has increased from 76:1 to 86:1 at the median. The CEO single total figure of remuneration has increased by approximately 17% 
versus last year and this increase is driven predominantly by an approximate 25% increase in estimated LTPP vesting value. Increases in salary, 
benefits in kind and pensions as a result of the increase to base salary are broadly offset by an approximate reduction of 11% in 2019/20 APP payout 
for the CEO. Excluding LTPP the total pay and benefits for the CEO has increased by 0.8% whilst the total pay and benefits for the reference 
employee at the median has increased by 2.4%, compared with last year.

Excluding estimated 2017 LTPP vesting, our UK median pay ratio is the same as last year at 38:1 and on a Group basis has marginally reduced to 
23:1 this year compared with 24:1 last year. The lower Group median pay ratio versus the UK reflects the higher labour cost in the US versus the UK, 
which is further influenced by the US locations in which we operate which have even higher labour costs than the US on average. The ratio of the pay 
of our Executive Director, UK, to the median UK employee is 41:1 and excluding the estimated 2017 LTPP vesting is 18:1.

This year the 2017 LTPP vesting represents some 56% of the CEO’s single total figure of remuneration. However, only 2% of UK-based employees 
will receive an estimated 2017 LTPP vest in our pay ratio calculations, and all of these employees are in the upper quartile of our ranked list and so 
are not selected as a 75th percentile (or below) reference employee. Removing the impact of 2017 LTPP vesting in our calculations results in lower 
ratios, for the reference employees of 49:1, 38:1 and 29:1 at the 25th, 50th and 75th percentiles respectively and these ratios are the same as last 
year. As employees advance through the Group, there will be the opportunity to receive higher rewards commensurate with increased accountability 
and market practice. 

The regulations require the total pay and benefits and the salary component of total pay and benefits for this year to be set out as follows:

Pay data 2019/20

CEO remuneration

UK employee 25th percentile

UK employee 50th percentile

UK employee 75th percentile

£34,521

£51,149

£60,913

£47,849

£61,842

£80,614

Flexibility is provided to adopt one of three methods for calculating the ratios. We have chosen Option A, which is a calculation based on the pay 
of all UK employees on a full-time equivalent basis, as this option is considered to be more statistically robust. The ratios are based on total pay 
and benefits inclusive of short-term and long-term incentives applicable for the respective financial year 1 April – 31 March. The reference employees 
at the 25th, 50th and 75th percentile have been determined by reference to pay and benefits as at the last day of the respective financial year, 
31 March, though estimates have been used for the respective APP payouts and performance outturns of the LTPP and dividend equivalents.

Corporate Governance

Directors’ Remuneration Report continued

Statement of implementation of remuneration policy in 2019/20 continued

All employees are eligible for a performance-based annual payment. Our principles for pay setting and progression in our wider workforce are the 
same as for our executives – mid-market approach to total reward, being sufficiently competitive to attract and retain high-calibre individuals without 
over-paying and providing the opportunity for individual development and career progression. The pay ratios reflect how remuneration arrangements 
differ, as accountability increases for more senior roles within the organisation, and in particular the ratios reflect the weighting towards long-term 
value creation and alignment with shareholder interests for the CEO.

We are satisfied that the median pay ratio reported this year is consistent with our wider pay, reward and progression policies for employees. 
The median reference employee falls within our collectively bargained employee population and has the opportunity for annual pay increases, 
annual performance payments and career progression and development opportunities.

Advisors to the Remuneration Committee 
The Committee received advice during 2019/20 from independent consultants Willis Towers Watson. Willis Towers Watson was selected by the 
Committee to become its independent advisor from 23 October 2017 following a competitive tendering process. Willis Towers Watson is a member 
of the Remuneration Consultants Group and has signed up to that group’s code of conduct. The Committee is satisfied that any potential conflicts 
were appropriately managed.

Work undertaken by Willis Towers Watson in its role as independent advisor to the Committee has included providing market information for the 
Executive Directors and other senior employees and for governance matters. This work has incurred fees of £57,488 incurred on the basis of time 
charged to perform services and deliverables. The Committee reviews the objectivity and independence of the advice it receives from its advisors 
each year. It is satisfied that Willis Towers Watson provided credible and professional advice. Willis Towers Watson also provided general and 
technical remuneration services in relation to employees below Board and Group Executive Committee level.

The Committee considers the views of the Chairman on the performance and remuneration of the CEO, and of the CEO on the performance and 
remuneration of the other members of the Executive Committee. The Committee is also supported by the Group General Counsel and Company 
Secretary, who acts as Secretary to the Committee, the Chief Human Resources Officer, the HR Director – Reward; and, as required, the Group 
Head of Pensions and Group Financial Controller. No other advisors have provided significant services to the Committee in the year.

Corporate Governance | Directors’ Remuneration Report

How our remuneration policy will be implemented in 2020/21

The remuneration policy adopted at the 2019 AGM will be implemented during 2020/21 as described below.

Salary
Salary increases will normally be in line with the increase awarded to other employees in the UK and US, subject to performance. Higher salary 
increases may also be awarded for a change in responsibility. Additionally, in line with the policy on recruitment remuneration, salaries for new 
directors may be set below market level initially and aligned to market level over time (provided the increase is merited by the individual’s contribution 
and performance).

As explained in the Remuneration Committee Chair’s Statement, for 2020/21 a salary increase for Andy Agg will be awarded and this will be effective 
from July in line with the rest of the workforce. Salary increases for John Pettigrew and Nicola Shaw will not be awarded at this time.

Pensions
The remuneration policy approved at the July 2019 AGM stated that new appointments would receive contributions of up to 20% of base salary. In 
addition to this, John Pettigrew and Nicola Shaw agreed progressive reductions from 30% to 20% of base salary. Implementation of this agreement 
is now underway and effective 1 April 2020, cash in lieu of pension contributions for each of John Pettigrew and Nicola Shaw have reduced to 26.7% 
and further reductions to 23.4% and then 20.0% will take place at 1 April 2021 and 1 April 2022 respectively. Andy Agg already receives the 
approved policy maximum of 20%. Further to the 2019 AGM the Committee agreed in November 2019 that newly appointed Executive Directors will 
receive annual contributions of up to 12% of basic salary for the DC pension scheme, or cash supplement in lieu. Further discussions on pension 
contributions will be conducted as part of the 2021 Directors’ Remuneration Policy review.

APP measures for 2020/21
Due to the uncertainty in the context of COVID-19, the Committee has opted not to finalise financial measures, associated weightings or targets at 
this time but intends to do so as soon as practicable. APP targets are considered commercially sensitive and consequently will be disclosed in the 
2020/21 Directors’ Remuneration Report.

Performance measures for LTPP to be awarded in 2020
Due to the uncertainty in the context of COVID-19, the Committee has opted not to finalise the targets for the 2020 LTPP financial measures. 
The weightings for these measure are Group RoE (16.67%) and Group Value Growth (83.33%). Group RoE will be measured over the first year of 
the three-year performance period and Group Value Growth will be measured over the entire three-year performance period, determining 1/6th and 
5/6ths of the total vesting outcome for the 2020 LTPP, respectively. LTPP awards are expected to be made later in the year and will be based on 
1 July 2020 salaries.

Fees for NEDs
Therese Esperdy was appointed as Non-executive Director to the National Grid USA Board in 2015 with an annual fee of £25,000 in addition to her 
current NED fees. We will not be increasing the Chairman’s fee or other NED fees at this time. Fees effective from 1 June 2019 remain unchanged 
and are set out in the table below.

Statement of Directors’ responsibilities

Each of the Directors, whose names and functions are listed on 
pages 66 – 67, confirms that:
•  to the best of their knowledge, the Group financial statements  

and the Parent Company financial statements, which have been 
prepared in accordance with IFRSs as issued by the IASB and 
IFRS as adopted by the European Union and UK GAAP FRS 101 
respectively, give a true and fair view of the assets, liabilities, 
financial position and profit of the Company on a consolidated and 
individual basis;

•  to the best of their knowledge, the Strategic Report contained in 
the Annual Report and Accounts includes a fair review of the 
development and performance of the business and the position of 
the Company on a consolidated and individual basis, together with a 
description of the principal risks and uncertainties that it faces; and

Company number: 4031152

The Directors are responsible for preparing the Annual Report and 
Accounts, including the Group financial statements and the Parent 
Company financial statements in accordance with applicable law 
and regulations.

Company law requires the Directors to prepare financial statements for 
each financial year. Under that law the Directors are required to prepare 
the Group financial statements in accordance with International Financial 
Reporting Standards (IFRSs) as adopted by the European Union and 
Article 4 of the IAS Regulation and have elected to prepare the Parent 
Company financial statements in accordance with United Kingdom 
Generally Accepted Accounting Practice (United Kingdom Accounting 
Standards and applicable law), including FRS 101 ‘Reduced Disclosure 
Framework’. Under company law, the Directors must not approve the 
accounts unless they are satisfied that they give a true and fair view of 
the state of affairs of the Group and Parent Company and of the profit 
or loss of the Group and Parent Company for that period.

In preparing the Group financial statements, International Accounting 
Standard 1 requires that Directors:
•  properly select and apply accounting policies;
•  present information, including accounting policies, in a manner that 

provides relevant, reliable, comparable and understandable 
information;

•  provide additional disclosures when compliance with the specific 

requirements in IFRSs are insufficient to enable users to understand 
the impact of particular transactions, other events and conditions 
on the entity’s financial position and financial performance; and

•  make an assessment of the Group’s ability to continue as a 

going concern.

In preparing the Parent Company financial statements, the Directors are 
required to:
•  select suitable accounting policies and then apply them consistently;
•  make judgments and accounting estimates that are reasonable 

and prudent;

•  state whether applicable UK Accounting Standards have been 

followed, subject to any material departures disclosed and explained 
in the financial statements; and

•  prepare the financial statements on the going concern basis 

unless it is inappropriate to presume that the Company will continue 
in business.

The Directors are responsible for keeping adequate accounting records 
that are sufficient to show and explain the Group and Parent Company’s 
transactions and disclose with reasonable accuracy at any time the 
financial position of the Group and Parent Company on a consolidated 
and individual basis, and to enable them to ensure that the Group 
financial statements comply with the Companies Act 2006. They are 
also responsible for safeguarding the assets of the Parent Company and 
its subsidiaries and hence for taking reasonable steps for the prevention 
and detection of fraud and other irregularities.

The Directors are responsible for the maintenance and integrity of the 
Company’s website. Legislation in the United Kingdom governing the 
preparation and dissemination of financial statements may differ from 
legislation in other jurisdictions.

Having made the requisite enquiries, so far as the Directors in office at 
the date of the approval of this Report are aware, there is no relevant 
audit information of which the auditors are unaware and each Director 
has taken all reasonable steps to make themselves aware of any 
relevant audit information and to establish that the auditors are aware 
of that information.

to the members of National Grid plc
Report on the audit of the financial statements

1. Opinion 

In our opinion:

•   the financial statements of National Grid plc (the ‘parent 

company’) and its subsidiaries (the ‘Group’) give a true and fair 
view of the state of the Group’s and of the parent company’s 
affairs as at 31 March 2020 and of the Group’s profit for the year 
then ended;

•   the Group financial statements have been properly prepared in 
accordance with International Financial Reporting Standards 
(IFRSs) as adopted by the European Union and IFRSs as issued 
by the International Accounting Standards Board (IASB);

•   the parent company financial statements have been properly 

prepared in accordance with United Kingdom Generally 
Accepted Accounting Practice, including Financial Reporting 
Standard 101 “Reduced Disclosure Framework”; and

•   the financial statements have been prepared in accordance with 

the requirements of the Companies Act 2006 and, as regards the 
Group financial statements, Article 4 of the IAS Regulation.

We have audited the financial statements, which comprise:

Group:
•  the consolidated income statement;
•  the consolidated statement of comprehensive income;
•  the consolidated statement of changes in equity;
•  the consolidated statement of financial position;
•  the consolidated cash flow statement; and
•  the related notes 1 to 39 to the consolidated financial statements.

Parent Company:
•  the parent company accounting policies;
•  the parent company balance sheet;
•  the parent company statement of changes in equity; and
•  the related notes 1 to 10 to the parent company financial statements.

The financial reporting framework that has been applied in the 
preparation of the Group financial statements is applicable law, IFRSs  
as adopted by the European Union and IFRSs as issued by the IASB. 
The financial reporting framework that has been applied in the 
preparation of the parent company financial statements is applicable  
law and United Kingdom Accounting Standards, including FRS 101 
“Reduced Disclosure Framework” (United Kingdom Generally Accepted 
Accounting Practice).

2. Basis for opinion
We conducted our audit in accordance with International Standards on 
Auditing (UK) (ISAs (UK)) and applicable law. Our responsibilities under 
those standards are further described in the auditor’s responsibilities  
for the audit of the financial statements section of our report. 

We are independent of the Group and the parent company in 
accordance with the ethical requirements that are relevant to our audit  
of the financial statements in the UK, including the Financial Reporting 
Council’s (the ‘FRC’s’) Ethical Standard as applied to listed public 
interest entities, and we have fulfilled our other ethical responsibilities in 
accordance with these requirements. The non-audit services provided 
to the Group and parent company for the year are disclosed in note 4  
to the financial statements. We confirm that the non-audit services 
prohibited by the FRC’s Ethical Standard were not provided to the  
Group or the parent company.

We believe that the audit evidence we have obtained is sufficient and 
appropriate to provide a basis for our opinion.

3. Summary of our audit approach

Key audit matters

The key audit matters that we identified in the current year were:
• Impact of COVID-19;
• Impact of climate change on property, plant and equipment;
• Environmental provisions;
• Classification of exceptional items;
• Net pension obligations; 
• Treasury derivative transactions; and 
• IT user access controls.

Changes in our key 
audit matters since  
the prior year

These key audit matters are consistent with those we identified in the prior year except that: 
• As a consequence of the COVID-19 outbreak, which has severely affected the UK and US economies, there are financial reporting 
impacts particularly with respect to key judgments, estimates and disclosures within the financial statements. In addition, there 
are potential financial control impacts as a consequence of remote working. This caused us to perform an updated audit risk 
assessment. Accordingly we have identified this as a key audit matter; and 

• The impact of climate change on property, plant and equipment has been identified as a new key audit matter due to the increase 

in shareholder focus and legislation enacted during the year in relation to “net-zero” carbon by 2050 commitments by the UK 
government and certain US states (specifically New York and Massachusetts) in which the Group operates. This has a potentially 
significant impact on the Group’s gas businesses and accordingly the estimated useful lives of its assets.

Materiality

Scoping

The materiality that we used for the Group financial statements was £120 million, which represents 5.1% of adjusted profit before tax 
(profit before tax excluding the impact of reported exceptional items and remeasurements) and 6.8% of statutory profit before tax.

Our scope covered six components of the Group in addition to procedures performed at the Group level. Of these, three were 
subjected to a full-scope audit whilst the remaining three were subject to specific procedures on certain account balances.

Our scoping covered 99% of the Group’s revenue; 97% of the Group’s gross assets; and 99% of the Group’s gross liabilities.

4. Conclusions relating to going concern, principal risks and viability statement

4.1. Going concern
We have reviewed the directors’ statement in note 1A to the financial statements about whether they considered it 
appropriate to adopt the going concern basis of accounting in preparing them and their identification of any material 
uncertainties to the Group’s and company’s ability to continue to operate as a going concern for a period of at least 
twelve months from the date of approval of the financial statements.

We considered as part of our risk assessment the nature of the Group, its business model and related risks including 
where relevant the impact of the COVID-19 pandemic and Brexit, the requirements of the applicable financial reporting 
framework and the system of internal control. We evaluated the directors’ assessment of the Group’s ability to continue 
as a going concern, including challenging the underlying data and key assumptions used to make the assessment, and 
evaluated the directors’ plans for future actions in relation to their going concern assessment.

We are required to state whether we have anything material to add or draw attention to in relation to the directors’ 
statement required by Listing Rule 9.8.6R(3) and report if the statement is materially inconsistent with our knowledge 
obtained in the audit.

Going concern is the basis of 
preparation of the financial 
statements that assumes an 
entity will remain in operation 
for a period of at least twelve 
months from the date of 
approval of the financial 
statements.

We confirm that we have nothing 
material to report, add or draw 
attention to in respect of these 
matters.

4.2. Principal risks and viability statement
Based solely on reading the directors’ statements and considering whether they were consistent with the knowledge we 
obtained in the course of the audit, including the knowledge obtained in the evaluation of the directors’ assessment of 
the Group’s and the company’s ability to continue as a going concern, we are required to state whether we have anything 
material to add or draw attention to in relation to:
• the disclosures on pages 23 – 25 that describe the principal risks, procedures to identify emerging risks, and an 

explanation of how these are being managed or mitigated;

• the directors’ confirmation on page 26 that they have carried out a robust assessment of the principal and emerging 

risks facing the Group, including those that would threaten its business model, future performance, solvency or 
liquidity; or

• the directors’ explanation on page 26 as to how they have assessed the prospects of the Group, over what period  

they have done so and why they consider that period to be appropriate, and their statement as to whether they have  
a reasonable expectation that the Group will be able to continue in operation and meet its liabilities as they fall due  
over the period of their assessment, including any related disclosures drawing attention to any necessary qualifications 
or assumptions.

We are also required to report whether the directors’ statement relating to the prospects of the Group required by Listing 
Rule 9.8.6R(3) is materially inconsistent with our knowledge obtained in the audit.

Viability means the ability of the 
Group to continue over the time 
horizon considered appropriate 
by the directors, which for 
National Grid is 5 years. 

We confirm that we have nothing 
material to report, add or draw 
attention to in respect of these 
matters.

5. Key audit matters
Key audit matters are those matters that, in our professional judgement, were of most significance in our audit of the financial statements of the current 
period and include the most significant assessed risks of material misstatement (whether or not due to fraud) that we identified. These matters 
included those which had the greatest effect on: the overall audit strategy, the allocation of resources in the audit and directing the efforts of the 
engagement team.

Throughout the course of our audit we identify risks of material misstatement (‘risks’). We consider both the likelihood of a risk and the potential 
magnitude of a misstatement in making the assessment. Certain risks are classified as ‘significant’ or ‘higher’ depending on their severity. The category 
of the risk determines the level of evidence we seek in providing assurance that the associated financial statement item is not materially misstated.

These matters were addressed in the context of our audit of the financial statements as a whole, and in forming our opinion thereon, and we do not 
provide a separate opinion on these matters.

5.1. Impact of COVID-19 

Key audit matter 
description

Account balances: Trade and other receivables. Refer to note 19 to the financial statements. Pensions and other 
post-retirement benefits. Refer to note 25 to the financial statements.

The COVID-19 pandemic has had a significant impact on the UK and US economies with consequences to the 
judgements and estimates made by the Group, principally in relation to the recoverability of US customer receivables 
and the valuation of certain pension assets. Refer to note 1E to the financial statements and the Audit Committee’s 
discussion on pages 76 – 78.

In March 2020 the COVID-19 pandemic resulted in the UK government and several US states in which the Group operates imposing 
lockdowns of their populations in order to stop the spread of the disease. This had a direct and severe impact on those economies 
as consumer spending decreased and unemployment rose at unprecedented rates, in turn severely impacting global demand and 
world financial markets. This has impacted the results of the Group for the 2020 financial year and is expected to continue to impact 
the Group for the remainder of FY21.
Management reassessed their controls framework, which encompassed a review of the ability to operate existing controls remotely 
and consideration of whether existing controls were suitable for addressing areas of new or increased risk. As a result of this 
assessment, a new COVID-19 entity-level control was implemented to assess the completeness of accounting considerations 
across the Group. Further, whilst there could be a potential impact upon a number of financial statement line items, management’s 
assessment determined that the primary risks that arose from the COVID-19 pandemic related to the valuation of:
• provisions for bad and doubtful debts in the US due to the increased uncertainty over customers’ ability to settle amounts when 

they fall due; and

• unquoted pension assets, particularly certain assets in the property and alternative investment portfolios which are subject to 

increased valuation uncertainties.

In calculating bad and doubtful debts, the key judgement relates to the requirement to incorporate ‘expected credit losses’ into the 
provision. This requires management to make forward-looking estimates of the expected level of losses which will be incurred on 
any outstanding trade receivables. In the US, unlike in the UK, the Group has retail customers. The regulatory moratorium in the  
US requiring the suspension of certain debt collection and customer termination activities has increased the level of estimation 
uncertainty related to the bad debt calculation in respect of US trade receivables. Management has considered relevant forward-
looking macroeconomic data in the US, as well as the effect on incurred losses experienced in the aftermath of the financial crisis of 
2008 and Superstorm Sandy in 2012 to inform their estimation. Accordingly, we have identified this as an area of ‘higher’ audit risk.

The key judgements related to the valuation of certain unquoted pension assets are discussed in the ‘net pension obligations’ key 
audit matter.

5.1. Impact of COVID-19 continued

Key audit matter 
description continued

A risk was also identified in relation to the impact of the pandemic on the Group’s cash flows and liquidity and accordingly its going 
concern analysis. Management performed a detailed analysis of the potential impact of the COVID-19 pandemic on revenue, profit 
and cash flows, in particular the impact on US customer collections. Possible cost mitigations were also considered. This detailed 
analysis also included consideration of a number of downside scenarios as to the duration of the lockdown measures, and concluded 
that no reasonably possible downside scenario existed wherein the Group would be unable to continue as a going concern. 

How the scope of our 
audit responded to the 
key audit matter

Related disclosure of management’s and the Board’s assessment of the ability to continue as a going concern, inclusive of the 
impact of the pandemic as a principal risk has been made in the Annual Report on page 25, and has been included as a 
consideration in the viability statement on page 26.

We performed controls testing at year end on areas of heightened risk, including the incremental COVID-19 specific control, and 
assessed whether management appropriately considered the related impact on existing controls.

Further, we held discussions within the Group and component engagement teams, with management, with our internal treasury, 
pensions and tax specialists and within the wider Deloitte network to identify the areas of risk to the financial statements as a  
result of the wider impacts of the pandemic. We used the outcome of these discussions to update our audit risk assessment and 
challenge management’s impact assessment. Our responses in respect of specific areas identified as risks related to COVID-19  
are outlined below. For these areas we also reviewed management’s disclosures in relation to the key judgements and estimates 
made in assessing the impact of COVID-19, inclusive of sensitivity disclosures related to the areas of estimation uncertainty. 

Provisions for bad and doubtful debts in the US: In challenging management’s assumptions related to the impact of the 
COVID-19 pandemic on the provision for bad and doubtful debts on US retail customers, we considered the extent to which  
the 2008 financial crisis and impact of Superstorm Sandy were reasonable data points to use in informing those estimates. We 
challenged management’s judgement in respect of the point in the range of calculated possible outcomes which management 
determined to be their best estimate.

Valuation of unquoted pension assets: We have described the procedures performed on the valuation of these pension assets 
in our ‘net pension obligation’ key audit matter.

Liquidity and ability to continue as a going concern: We have assessed the going concern model prepared by management, 
which considered the impact of COVID-19. We assessed the underlying assumptions, inclusive of mitigating cost actions being 
taken based on our understanding of the business and knowledge of the industry in which the Group operates. Where impacts 
were significant, our component audit teams were also involved in a more granular challenge of local management’s forecasts. 
Further, we assessed management’s evaluation of liquidity and loan covenant compliance over the period of assessment to confirm 
no breaches are anticipated over this timeframe.

Key observations

Our testing confirmed the incremental COVID-19 specific control operated effectively.

We concluded that management’s judgements and estimates made in determining the incremental level of expected credit losses 
as a consequence of the COVID-19 pandemic are reasonable.

Our conclusion on the valuation of certain pension assets is set out in our ‘net pension obligation’ key audit matter.

Our conclusion on going concern is set out in the ‘Conclusions relating to going concern, principal risks and viability statement’ 
section of this report.

We concluded that management’s disclosures included in note 1E to the financial statements in respect of the key judgements and 
areas of estimation uncertainty are appropriate.

5.2. The impact of climate change on property, plant and equipment

Key audit matter 
description

Account balance: Property, plant and equipment. Refer to notes 1E and 13 to the financial statements and the Audit 
Committee’s discussion on pages 76 – 78.

The UK government and certain of the US states in which the Group operates have enacted legislation and established targets in 
respect of net zero carbon emissions by 2050. Accordingly climate change represents a strategic challenge for the Group, which 
has also set targets for reducing direct greenhouse gas emissions by the same date. 

Natural gas, when burned, emits carbon dioxide and is considered a greenhouse gas. Therefore, the strategic challenge relates to 
the potential future use of the Group’s assets used to facilitate gas transmission services in the UK and gas distribution services in 
the US in the period approaching 2050 and beyond. The remaining useful economic life of the Group’s gas assets is up to 50 years 
in the UK and 80 in the US, extending well beyond the 2050 “net zero” commitment date. As described in note 13 to the financial 
statements, the impact of changing the useful economic lives of all of the Group’s gas assets, such that they would be fully 
depreciated by 2050, would be an increase in the annual depreciation expense of £188 million, and such that they would be fully 
depreciated by 2060, would be an increase in the annual depreciation expense of £79 million. 

As the continued use of natural gas as a primary energy source beyond 2050 appears to be in conflict with net zero targets and the 
impact of shortening the useful lives of the gas assets to 2050 has a material impact on annual depreciation, we identified a ‘higher’ 
risk related to the financial statement impact of those commitments, specifically pinpointed to management’s judgement in 
determining the useful lives of gas assets in the context of the net zero commitments. 

As described in note 13 to the financial statements and in the Audit Committee Report (page 78), management performed a 
detailed assessment of the potential uses for the Group’s gas assets as part of their consideration around whether developments in 
the UK and US towards binding carbon reduction targets should trigger any changes to National Grid’s estimates, judgements or 
disclosures, especially regarding gas asset lives. Management’s assessment included an overview of the legislative changes in the 
UK and US, and an evaluation of the possible future use of National Grid’s networks in a net zero energy system. 

Management’s best estimate of the useful economic lives of US gas assets, across all states in which it operates, is based on  
the depreciable life identified through depreciation studies for each asset and are approved by the respective state regulator. 
Accordingly, in the US, the IFRS asset depreciable lives are identical to those agreed by the Group’s regulators for regulatory 
purposes. Management concluded it is probable that there will be a role for its US gas networks post 2050 under a range of 
possible scenarios, and there is nothing at present to suggest that asset lives should be shortened at this point. 

In the UK, National Grid Gas Transmission (NGGT) owns and operates the UK gas transmission network (NTS). Pipelines represent 
the vast majority of the value that will be undepreciated by 2050. Having analysed the potential decarbonisation pathways, 
management has identified numerous potential uses for the Group’s UK gas pipeline assets in a net zero energy system including 
for the continued transmission of natural gas as a back-up fuel or in order for blue hydrogen to be produced alongside carbon 
capture and storage; and the transmission of hydrogen or other low or zero carbon gases.

5.2. The impact of climate change on property, plant and equipment continued

Key audit matter 
description continued

Management concluded that their best estimate for the useful economic life of the National Transmission System (NTS) pipeline assets 
in the UK is 50 years (or until 2070) as this best represents when the assets will continue to support business operations in the UK.

How the scope of our 
audit responded to the 
key audit matter

Management and the Audit Committee determined that in light of the evolving legislative developments and increasing investor 
attention, disclosure of a key judgement in relation to the potential future use of the Group’s gas assets post-2050 and disclosure 
of the gas asset lives as a key estimate (note 1E to the financial statements), with appropriate sensitivity analysis (note 13 to the 
financial statements) were appropriate.

We tested management’s internal control over the accounting for and disclosure of the potential impacts associated with the energy 
transition and climate change.
We challenged management’s judgement that the useful lives of the Group’s gas assets extend beyond 2050 in light of the different 
goals, commitments and legislation relating to net zero in the UK and the US states in which the Group operates by: 
• reviewing potential strategic pathways to achieve net zero targets;
• obtaining and reviewing government plans in the US and UK for achieving net zero which we compared to the potential strategic 

pathways;

• reviewing information from the Group’s regulators, including price controls in the UK and rate cases in the US, to consider 

whether they presented any contradictory evidence; 

• performing an assessment of the likelihood of occurrence of alternative scenarios for achieving net zero targets;
• considering the potential for re-purposing the Group’s gas networks for alternative uses, and in particular for transporting 

hydrogen; and

• reviewing a number of external reports including: Hydrogen in a low-carbon economy and Net Zero – Technical report, produced 

by the Committee on Climate Change; the UK’s draft integrated National Energy and Climate Plan (NECP) produced by the 
Department for Business, Energy & Industrial Strategy; and searching for contradictory evidence in respect of management’s 
judgements.

We utilised our sustainability specialists to review management’s key assumptions and to challenge the viability of some of the 
technological advances presented within the strategic pathways. We also consulted with Deloitte specialists in other countries 
regarding the suitability of existing gas infrastructure for transporting hydrogen.

We also reviewed the disclosures set out in note 1 to the financial statements and the sensitivity analysis set out in note 13 to the 
financial statements regarding the carrying value of the useful economic lives of the Group’s gas assets.

Key observations

Our testing confirmed that the relevant controls over management’s assessment of the impact of the energy transition and climate 
change operated effectively.

We observe that whilst some indicators do exist suggesting that the useful economic lives of the Group’s gas assets may be limited 
to 2050, these are mitigated by other statements by governments and advisory bodies which suggest gas, and therefore gas 
transmission and distribution assets, will continue to have a role beyond 2050. Furthermore, the emergence of a substantial 
hydrogen infrastructure could introduce a longer term role for National Grid gas assets past 2050, if technological developments 
allow the utilisation of existing assets in this infrastructure.

Whilst the targets, goals and ambitions in respect of net zero have now been formalised in legislation in the jurisdictions in which  
the Group operates, there is widespread recognition that work needs to be done to define the possible future decarbonisation 
pathways. We note that whilst state energy policy in the US states in which the Group operates is codified by the legislature, it is the 
regulators who are charged with implementing state energy policies. We concluded it was reasonable to assume that there will be  
a valuable use for the Group’s US gas assets beyond 2050 and that in the absence of any determination by the Group’s regulators, 
it continues to be reasonable to use the regulatory asset lives for the calculation of depreciation in accordance with IFRS. 

In the UK, we note that there is no alignment between the useful lives of the Group’s gas assets for IFRS depreciation purposes, 
and the period of recovery of the regulatory asset value under regulation. Nevertheless, we conclude that it is reasonable to assume 
that there will be a valuable use for these assets until 2070.

We consider the disclosures in note 1 to the financial statements and the sensitivity analysis in note 13 to the financial statements to 
be appropriate.

We are satisfied that management’s other disclosures in the Annual Report relating to the uncertainty surrounding the future use of 
the Group’s gas assets are consistent with the financial statements and our understanding of the business.

5.3. Environmental provisions 

Key audit matter 
description

Account balance: Provisions. Refer to notes 1E, 26 and 35 to the financial statements and the Audit Committee’s 
discussion on pages 76 – 78. 

At 31 March 2020 the Group has £2,071 million (2019: £1,639 million) of environmental provisions, of which £175 million (2019: £189 
million) are in the UK and £1,896 million (2019: £1,450 million) in the US.

The Group’s environmental provisions relate to a number of sites owned and managed by the Group together with certain US sites 
which are no longer owned. In the US the provision is in respect of 257 sites which vary in the level of clean-up required. Of the total 
US environmental provisions of £1,896 million, more than half relates to three former sites which were identified by the Environmental 
Protection Agency (EPA) as sites of significant contamination (Superfund sites). The EPA has the authority to force the parties 
responsible for the contamination of these sites either to perform clean-ups or reimburse the government for work led by the EPA.

There are a number of estimation uncertainties across all of the sites. We identified a ‘higher’ risk in relation to certain sites which 
are complicated because of their size, the number of parties involved and/or the stage of remediation the project is at. The 
uncertainties that exist in relation to these sites include: the impact of regulation; the form, timing, extent and associated cost of 
remediation needed; the methods and technologies used in remediation; the allocation of responsibility; and the discount rates 
applied to the forecast cash flows.

There were significant increases in the provisions recorded for two US Superfund sites in the year and a small reduction at the third. 
We determined that the estimation of the undiscounted cash outflows specific to these sites was the most significant and sensitive 
to a change in reasonably possible outcomes.

In respect of the US Superfund site with the most significant increase in provision, there were two reasons for management’s 
reassessment of the estimated cash outflows. An updated design report was received in the year which indicated that the work 
required to remediate the site was more extensive than had previously been expected, resulting in a higher estimated total cost. In 
addition, following an EPA order management increased its estimate of the share of the costs the Group would bear amongst the 
Potentially Responsible Parties (PRPs).

Key audit matter 
description continued

Regarding the other Superfund site with a significantly increased provision, an updated survey clarified the extent of remediation 
work which needs to be performed, leading to an increase in the Group’s share of the expected costs.

How the scope of our 
audit responded to the 
key audit matter

Management are required to make judgements in selecting an appropriate discount rate which reflects changes in UK gilt and US 
treasury rates as current market assessments of the time value of money. The Group decreased the real discount rates applied to 
the undiscounted cash flows from 1% in the prior year to 0.5% for both the UK and the US provisions. 

We tested the controls over the compilation of forecast cash flows and the determination of the discount rate.

We performed detailed risk assessments to categorise US sites based on size and the level of estimation uncertainty, determined 
by the stage of the remediation and the extent of work required. In respect of US sites other than the Superfund sites, we worked 
with our internal environmental specialists to assess cash flow estimates across a sample of sites. In order to assess the 
completeness of the year end liabilities we also completed public domain searches on Federal databases across all Group 
subsidiaries to determine whether any relevant costs or applicable sites were omitted. 

With respect to the US Superfund sites, we agreed underlying cost assumptions to third-party build information, approved 
engineering design reports and other benchmarks and utilised our internal environmental provision specialists to assist us in 
evaluating managements’ key assumptions. We also considered information obtained from the Group’s legal advisors and  
relevant EPA correspondence in our evaluation of the recorded provisions.

We performed additional procedures on the site with the most significant increase in provision. Specifically relating to the 
judgement over the estimated allocation of total remediation costs, we made enquiries of the Group’s internal legal counsel and 
obtained analysis directly from external legal counsel. With the assistance of our internal environmental specialists, we used this 
additional information to determine independently a range of potential outcomes and allocations of remediation costs at the site, 
and used this to assess management’s estimate.

We challenged the methodology that management has adopted for calculating the discount rate with the support of our internal 
valuation specialists. In addition, we independently calculated an appropriate discount rate range and used this to assess 
management’s rate. 

Key observations

Our testing confirmed that the relevant controls over the compilation of forecast cash flows and the determination of the discount 
rate were operating effectively.

We found the total cost assumptions associated with all of the tested sites to be reasonable, including the US Superfund sites. In 
respect of the US Superfund sites we are satisfied that management’s estimate of the proportion of costs expected to be allocated 
to the Group are within our independently calculated range. 

We consider the decrease in real discount rates from 1% to 0.5% applied in the UK and US to be reasonable based on the 
movement in gilts and treasury yields.

We noted that the assumptions and judgments that are required to formulate the provisions mean that the range of possible 
outcomes is broad. In respect of the Superfund site with the most significant increase in provision, as a consequence of the 
developments in the year, the level of uncertainty regarding the Group’s share of final costs has reduced. However, there continues 
to be a risk of further increases and we note that the remediation at the other two Superfund sites is less advanced and accordingly 
at risk of future increases. 

We are satisfied with the Group’s disclosures of environmental provisions in light of the underlying assumptions and accounting 
judgments made.

5.4. Classification of exceptional items 

Key audit matter 
description

Account balance: Operating costs (included in the exceptional items and remeasurements column). Refer to notes 1E 
and 5 to the financial statements and the Audit Committee’s discussion on pages 76 – 78.

The Consolidated Income Statement separately identifies exceptional items and certain remeasurements (the ‘middle column’). This 
results in focus being placed on what management refer to as ‘business performance’ or ‘adjusted profit’. 
Adjusted profit is a critical measure for stakeholders and is one of the principal measures which the Board uses to review the 
performance of the Group’s segments. In addition, underlying profit, which is derived from adjusted profit, is another widely used 
measure and is used in determining aspects of executive remuneration. Accordingly, the classification of items in the middle column 
is important for users of the financial statements. Consistency in the identification and presentation of these items is also important 
to ensure comparability of year-on-year reporting in the Annual Report and Accounts.
There is judgement in the classification and accuracy of the amounts determined to be exceptional in accordance the Group’s 
exceptional items framework and any amounts so classified impact the adjusted profit of the Group.
In the current year management classified the following items as exceptional charges in the middle column:
• Environmental charges of £402 million – Relating to the re-evaluation of estimates of total remediation costs and cost sharing 
allocations borne by the Group for the three US Superfund sites, as well as the impact of the change in the real discount rate 
applied to the estimated undiscounted cash flows for all environmental provisions; and

• Deferred tax arising on the reversal of the previously enacted reduction in the UK corporation tax rate of £192 million.

The key judgements related to the calculation of the environmental charges have been discussed in the ‘environmental provisions’ 
key audit matter.

5.4. Classification of exceptional items continued

How the scope of our 
audit responded to the 
key audit matter

We have tested the controls over the classification and accuracy of the amounts presented as exceptional items in the middle column. 

We have obtained the Group’s exceptional items framework and assessed the reasonableness of the framework for identifying items 
to be classified as exceptional. We assessed whether the classification of each of the items classified as exceptional complies with 
the approved framework and ESMA guidance and is reasonable. In making this assessment we also considered the consistency of 
application of the framework year on year. We substantiated the nature and quantum of significant individual items by examining 
appropriate evidence. 

We also considered other items which were not identified as exceptional in the context of management’s exceptional items 
framework as part of our challenge of management’s conclusions thereon, such as the provision for bad and doubtful debts in the 
US which was increased in the current year on account of the impact of COVID-19 and the related cessation of certain collection 
activities and disconnection of customers for non-payments.

Key observations

Our testing confirmed that the relevant controls over the classification and accuracy of the amounts presented as exceptional items 
in the middle column were found to be operating effectively.

We determined that the amounts disclosed as exceptional were so classified in accordance with the Audit Committee approved 
exceptional items framework and that the framework has been applied consistently with prior years.

Specifically, the classification of material increases in environmental provisions at the three Superfund sites and the impact on 
deferred tax balances of a change in tax rates have been classified as exceptional in prior years. We concur that the additional US 
bad debt charge should not be exceptional as it would represent just part of an amount calculated in accordance with IFRS.

5.5. Net pension obligations 

Key audit matter 
description

Account balance: Pensions and other post-retirement benefit obligations. Refer to notes 1E, 25 and 35 to the financial 
statements and the Audit Committee’s discussion on pages 76 – 78. 

Substantially all of the Group’s employees are members of one of a number of pension schemes in either the UK or US. These 
pension schemes include both defined benefit and defined contribution schemes. Healthcare and life insurance benefits are also 
provided to eligible retired US employees.

There are significant assumptions used in the valuations of the defined benefit obligations, which as at 31 March 2020 represent a 
liability of £24.6 billion (2019: £24.9 billion), and valuations of unquoted pension assets (‘unquoted assets’), which as at 31 March 
2020 make up £11.4 billion (2019: £8.4 billion) out of scheme assets of £23.7 billion (2019: £24.8 billion).

The critical judgements relating to the pension obligations include inflation assumptions, discount rates, mortality assumptions and 
future salary changes applied to active members. The setting of these assumptions is complex and changes to them can have a 
material impact on the value of pension obligations. Management uses external actuaries to assist in determining these 
assumptions. Accordingly, we have identified certain of these assumptions to be ‘higher’ audit risks.

Unlike the fair value of other assets that are readily observable and therefore more easily independently corroborated, the valuation 
of unquoted pension assets classified is inherently subjective. As such there is significant judgement in determining the fair value  
of these assets including the selection of the valuation methodology and other critical assumptions. The COVID-19 pandemic has 
resulted in the valuation of certain property assets being subject to increased uncertainty. In addition the valuation of certain 
unquoted investments including those held in private equity portfolios are subject to an unusually high level of uncertainty due to the 
most recent valuations on them being performed prior to the significant economic impacts of the COVID-19 pandemic. For these 
investments, management engaged external experts to assess the economic impact of COVID-19 on the asset valuations as at year 
end, including property specialists who assessed the value of the property portfolio held within pension assets. Accordingly, we 
have identified this as an area of ‘higher’ audit risk.

In the UK, the Group entered into two buy-in policies in the year. The Section A policy was entered into in August 2019, with the 
Section B policy completing in November 2019. The transactions involve the transfer of certain pension assets in the form of gilts 
and cash, valued at £2.8 billion and £1.6 billion respectively, in return for bulk annuity policies, with the intention of mitigating 
longevity risk. The transactions represent part of the Group’s long term de-risking strategy, of a similar nature to the longevity swap 
entered into in 2018. Under a buy-in transaction the ultimate obligation to pay the members remains with the scheme and is hence 
retained within the Group’s pension obligations; the bulk annuity is considered a qualifying insurance policy and is recognised at the 
valuation of the obligation it covers as an asset to the scheme. At the time of the transactions, the member obligations to which the 
policies relate were valued at £2.4 billion for Section A and £1.3 billion for Section B resulting in the recognition of actuarial losses of 
£700 million being recognised in Other Comprehensive Income, as disclosed in note 25 to the financial statements.

How the scope of our 
audit responded to the 
key audit matter

We tested the controls over the valuation of unquoted pension assets and over the critical assumptions used in determining the 
valuation of the pension obligations.

We engaged internal actuarial experts to assist in testing the discount rates used in calculating the pension obligations. We 
independently calculated appropriate discount rates and compared these to management’s rates. 

Our actuarial experts also assisted us in benchmarking and challenging the other assumptions used by management in determining 
the value of pension obligations particularly focusing on inflation, salary growth and mortality rates; this included comparing the 
inputs and assumptions used in determining the valuation of the Group’s schemes to those used in comparable pension plans and/
or our internal benchmarks. 

Additionally, we considered the competence, capability and objectivity of the independent actuaries engaged by the Group to 
perform valuations of the relevant schemes and where applicable, of unquoted assets.

We engaged internal specialists to challenge management’s valuation of certain unquoted scheme assets. Our work included 
assessing the reasonableness of the valuation methodologies applied, reviewing publically available information on these assets, 
comparing the valuations to internal benchmarks and confirmation of inputs used by management to determine the asset values.

Further, our actuarial experts assisted us with the assessment of management’s assumptions and valuation methodology related to 
the buy-ins and we consulted with technical experts as to the correct accounting treatment.

Key observations

Our testing confirmed that the relevant controls over the valuation of unquoted pension assets and over the critical assumptions 
used in determining the valuation of the pension obligations operated effectively.

We judge the discount rates and other key actuarial assumptions used by management to be within our internally developed 
reasonable range or consistent with our internally developed assumptions.

5. Key audit matters continued

5.5. Net pension obligations continued

Key observations 
continued

We note that the recognition of the actuarial loss on the buy-in transactions, representing the difference between the price paid and 
the value of the obligations covered by the buy-in policies is appropriately recognised in OCI as it is treated as a change in the fair 
value of plan assets. We assessed the appropriateness of the related disclosures in note 25 to the financial statements and 
consider them to be reasonable.

We consider management’s valuations of the unquoted investments to be reasonable and the disclosures in note 1E to the financial 
statements regarding the estimation uncertainty and in note 35 to the financial statements regarding the sensitivity of the pension 
assets balance to the valuation of unquoted assets to be appropriate.

5.6. Treasury derivative transactions 

Key audit matter 
description

Account balances: Derivative financial assets and derivative financial liabilities. Refer to notes 17 and 32 to the 
financial statements.

The Group mitigates the exposure to interest rate and foreign exchange rate risks with risk management activities including the use 
of derivatives such as cross-currency and interest rate swaps. The Group designates derivatives in hedge relationships where they 
judge this to meet the requirements of IFRS 9. Due to the technical nature of this assessment, we have identified it as a ‘higher’ 
audit risk. At 31 March 2020 the Group had derivative financial assets of £1,342 million (31 March 2019: £1,153 million) and 
derivative financial liabilities of £1,334 million (31 March 2019: £1,183 million). 

The valuation of the derivative portfolio requires management to make certain assumptions and judgements in particular around the 
valuation methodologies adopted and the discount rate to be applied to forecast cash flows.

The portfolio also includes ‘level 3’ derivative financial liabilities of £245 million (31 March 2019: £216 million) for which unobservable 
inputs that are significant to the fair value measurement must be used in the valuation models. This results in management having 
to make estimates in relation to unobservable inputs, which increase the complexity and level of estimation uncertainty, and there is 
judgement involved in determining the methodology used to fair value these derivatives. Accordingly, we have identified this as an 
area of ‘higher’ audit risk.

How the scope of our 
audit responded to the 
key audit matter

We have tested the controls over the recording and valuation of derivative financial instruments. This has included testing of the 
review controls performed by management over the valuations and its challenge of the estimates made.

In conjunction with our treasury specialists we have tested a sample of the valuation models used by management, including a 
challenge of the assumptions therein, to confirm the appropriateness of the valuation methodology adopted and the assumptions 
applied. We have obtained third party confirmations to test the completeness and accuracy of the information held within the 
Group’s treasury management system. 

We have assessed the appropriateness of the hedge documentation, eligibility of designations and hedge effectiveness testing 
performed by management and tested the disclosures within the financial statements.

We assessed whether the representation of items in the cash flow statement to reflect the change in accounting policy have been 
appropriately disclosed.

Key observations

Our testing confirmed that the relevant controls over the recording and valuation of derivative financial instruments were effective.

We conclude that the valuation of derivatives and the Group’s use of hedge accounting is appropriate.

We are satisfied that the disclosures in respect of the cash flow statement accounting policy change, and the amounts represented 
in the prior year to reflect the updated policy, are appropriate.

5.7. IT user access controls 

Key audit matter 
description

IT systems fulfil a critical role in the Group’s financial reporting and accordingly IT user access control deficiencies 
potentially impact all account balances. Refer additionally to the Audit Committee’s discussion of significant issues 
on pages 76 – 78.

In the past two financial years (ended on 31 March 2019 and 31 March 2018), we identified deficiencies relating to segregation of 
duties, control over privileged access and user access management both within the Group and the Group’s IT service organisations 
(together ‘access deficiencies’). The deficiencies identified increased the risk that individuals within the Group and at service 
organisations had inappropriate access during the period. 

Management continued executing on their remediation programme commenced during the year ended 31 March 2018 in order to 
strengthen the IT control framework, and substantially completed the programme. 

The existence of deficiencies during the year results in an increased risk that data and reports from the affected systems are not reliable.

The level of risk ascribed to our work in this area is dependent on the nature and complexity of the controls themselves and the 
balances within the financial statements the controls address.

How the scope of our 
audit responded to the 
key audit matter

In responding to the access deficiencies for in scope IT systems and the associated IT infrastructure, we have determined the 
impact that inappropriate levels of access throughout the year could feasibly have had on the affected systems and account 
balances including assessing the likelihood of inappropriate user access impacting the financial statements. Further, we tested 
controls implemented by management to identify instances of the use of inappropriate access, as well as mitigating controls 
included within management’s remediation programme. Where no such controls existed, we extended the scope of our audit  
such that we have not placed reliance on controls for information produced or held in the impacted systems.

Key observations

A number of the deficiencies identified as unremediated in the prior year were remediated by year-end. We do not consider the 
remaining deficiencies to be significant and we found the mitigating controls implemented by management operated effectively. 

Due to the fact that the newly remediated controls did not operate for the entire year, we conducted a largely substantive audit in 
the areas impacted by the access deficiencies. We continued to rely on controls in certain areas where the IT systems were not 
impacted by the access deficiencies.

6. Our application of materiality

6.1. Materiality

We define materiality as the magnitude of misstatement in the financial statements that makes it probable that the economic decisions of a 
reasonably knowledgeable person would be changed or influenced. We use materiality both in planning the scope of our audit work and in 
evaluating the results of our work.

Based on our professional judgement, we determined materiality for the financial statements as a whole as follows:

Group financial statements

Parent company financial statements

Materiality

£120 million (2019: £124 million).

£100 million (2019: £100 million).

Basis for 
determining 
materiality

Our determined materiality represents 5.1% of adjusted profit 
before tax and 6.8% of statutory profit before tax.

1.2% of net assets. 

Adjusted profit before tax is profit before tax, exceptional items and 
remeasurements as disclosed in the consolidated income 
statement. Prior year materiality was determined on a similar basis.

Rationale for 
the benchmark 
applied

We consider adjusted profit before tax to be an important 
benchmark of the performance of the Group. We consider it 
appropriate to adjust for exceptional items and remeasurements  
as these items are volatile and not reflective of the underlying 
performance of the Group.

As the Company is non-trading, operates primarily as a holding 
company for the Group’s trading entities, and is not profit orientated, 
we believe the net asset position is the most appropriate benchmark 
to use. 

We conducted an assessment of which line items we understand 
to be the most important to investors and analysts by reviewing 
analyst reports and National Grid’s communications to 
shareholders and lenders, as well as the communications of  
peer companies. This assessment resulted in us considering  
the financial statement line items above. 

Profit before tax is the benchmark ordinarily considered by us  
when auditing listed entities. It provides comparability against other 
companies across all sectors, but has limitations when auditing 
companies whose earnings are impacted by items which can be 
volatile from one period to the next, and therefore may not be 
representative of the volume of transactions and the overall size of 
the business in a given year, or where the impact of volatility may 
result in the recognition of material income or charges in a 
particular year.

Whilst not an IFRS measure, adjusted profit is one of the key 
metrics communicated by management in National Grid’s results 
announcements. It excludes some of the volatility arising from 
changes in fair values of financial assets and liabilities as well as 
“exceptional items” and this was the key measure applied in the 
prior year.

6.2. Performance materiality

We set performance materiality at a level lower than materiality to reduce the probability that, in aggregate, uncorrected and undetected misstatements exceed the 
materiality for the financial statements as a whole. Group performance materiality was set at £92.0 million for the 2020 audit (2019: £86.8 million), or 77% of Group 
materiality (2019: 70%). In determining to increase performance materiality, we considered the following factors:
• our cumulative experience from prior year audits;
• the level of corrected and uncorrected misstatements identified;
• our risk assessment, including our understanding of the entity and its environment; and
• our assessment of the Group’s overall control environment.

6.3. Error reporting threshold

We agreed with the Audit Committee that we would report to the Committee all audit differences in excess of £6.0 million (2019: £6.2 million), as well as differences 
below that threshold which, in our view, warranted reporting on qualitative grounds. We also report to the Audit Committee on disclosure matters that we identified 
when assessing the overall presentation of the financial statements.

7. An overview of the scope of our audit

The following significant components of the Group were identified in our audit planning: UK Electricity Transmission, UK Gas Transmission and US Regulated. Each 
of these components was subjected to a full-scope audit for Group reporting purposes, completed to the individual component materiality level discussed above. 

As each of the financially significant components maintains separate financial records we have engaged component auditors from the Deloitte member firms in  
the US or the UK to perform procedures at these components on our behalf. This approach allows us to engage local auditors who have appropriate knowledge  
of local regulations to perform this audit work. We issued detailed instructions to the component auditors and directed and supervised their work through a number 
of visits to the component auditors during the planning and performance stages of our audit alongside frequent remote communication and review of their work.  
In response to the COVID-19 pandemic which limited our ability to make component visits after the year end, frequent calls were held between the Group and 
component teams and remote access to relevant documents was provided.

Our oversight of component auditors focused on the planning of their audit work and key judgements made. In particular, our supervision and direction focused on 
the work performed in relation to key audit matters including internal controls (including general IT controls), environmental provisions, pensions, treasury derivative 
transactions and the classification of exceptional items. As part of our monitoring of component auditors we have also attended key local audit meetings.

Additionally our audit planning identified the following non-significant components where we consider there to be a reasonable possibility of material misstatement 
in specific items within the financial statements: UK Property, the Isle of Grain LNG terminal and the Metering business. Accordingly, we have directed component 
auditors to perform specific audit procedures in relation to material account balances and analytical procedures on the respective income statements and 
statements of financial position for these components. The work on these components is carried out by the same component audit team as for the UK Electricity 
Transmission and UK Gas Transmission components.

In addition to the work performed at a component level the Group audit team also performed audit procedures on the parent company financial statements, 
including but not limited to corporate activities such as treasury and pensions as well as on the consolidated financial statements themselves, including entity-level 
controls, litigation provisions, the consolidation, financial statement disclosures and risk assessment work on components not included elsewhere in the scope of 
our audit. The Group audit team also led the work in connection with the impact of climate change on the useful lives of the Group’s gas assets and co-ordinated 
certain procedures performed on key areas, such as environmental provisions, where audit work is performed by both the Group and component audit teams as 
well as analytical reviews on out-of-scope components.

8. Other information

The directors are responsible for the other information. The other information comprises the information included in the Annual 
Report, other than the financial statements and our auditor’s report thereon.

We have nothing to report in 
respect of these matters.

Our opinion on the financial statements does not cover the other information and, except to the extent otherwise explicitly 
stated in our report, we do not express any form of assurance conclusion thereon.

In connection with our audit of the financial statements, our responsibility is to read the other information and, in doing so, 
consider whether the other information is materially inconsistent with the financial statements or our knowledge obtained in  
the audit or otherwise appears to be materially misstated.

If we identify such material inconsistencies or apparent material misstatements, we are required to determine whether there is a 
material misstatement in the financial statements or a material misstatement of the other information. If, based on the work we 
have performed, we conclude that there is a material misstatement of this other information, we are required to report that fact.

In this context, matters that we are specifically required to report to you as uncorrected material misstatements of the other 
information include where we conclude that:
• Fair, balanced and understandable – the statement given by the directors that they consider the Annual Report and 
financial statements taken as a whole is fair, balanced and understandable and provides the information necessary for 
shareholders to assess the Group’s position and performance, business model and strategy, is materially inconsistent with 
our knowledge obtained in the audit; or

• Audit Committee reporting – the section describing the work of the Audit Committee does not appropriately address 

matters communicated by us to the Audit Committee; or

• Directors’ statement of compliance with the UK Corporate Governance Code – the parts of the directors’ statement 
required under the Listing Rules relating to the Company’s compliance with the UK Corporate Governance Code containing 
provisions specified for review by the auditor in accordance with Listing Rule 9.8.10R(2) do not properly disclose a departure 
from a relevant provision of the UK Corporate Governance Code.

9. Responsibilities of directors

As explained more fully in the directors’ responsibilities statement, the directors are responsible for the preparation of the financial statements and for being 
satisfied that they give a true and fair view, and for such internal control as the directors determine is necessary to enable the preparation of financial statements 
that are free from material misstatement, whether due to fraud or error.

In preparing the financial statements, the directors are responsible for assessing the Group’s and the parent company’s ability to continue as a going concern, 
disclosing as applicable, matters related to going concern and using the going concern basis of accounting unless the directors either intend to liquidate the  
Group or the parent company or to cease operations, or have no realistic alternative but to do so.

10.  Auditor’s responsibilities for the audit of the financial statements

Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or 
error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted 
in accordance with ISAs (UK) will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, 
individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements.

Details of the extent to which the audit was considered capable of detecting irregularities, including fraud and non-compliance with laws and regulations are set out below.

A further description of our responsibilities for the audit of the financial statements is located on the FRC’s website at: www.frc.org.uk/auditorsresponsibilities. This 
description forms part of our auditor’s report.

11. Extent to which the audit was considered capable of detecting irregularities, including fraud

We identify and assess the risks of material misstatement of the financial statements, whether due to fraud or error, and then design and perform audit procedures 
responsive to those risks, including obtaining audit evidence that is sufficient and appropriate to provide a basis for our opinion.

11.1. Identifying and assessing potential risks related to irregularities

In identifying and assessing risks of material misstatement in respect of irregularities, including fraud and non-compliance with laws and regulations, we considered 
the following:
• the nature of the industry and sector, control environment and business performance including the design of the Group’s remuneration policies, key drivers for 

directors’ remuneration, bonus levels and performance targets;

• results of our enquiries of management, internal audit and the Audit Committee about their own identification and assessment of the risks of irregularities; 
• any matters we identified having obtained and reviewed the Group’s documentation of their policies and procedures relating to:

• identifying, evaluating and complying with laws and regulations and whether they were aware of any instances of non-compliance;
• detecting and responding to the risks of fraud and whether they have knowledge of any actual, suspected or alleged fraud;
• the internal controls established to mitigate risks of fraud or non-compliance with laws and regulations;

• the matters discussed among the audit engagement team including significant component audit teams and involving relevant internal specialists, including  
tax, pensions, IT, and treasury specialists regarding how and where fraud might occur in the financial statements and any potential indicators of fraud. The 
engagement team includes audit partners and staff who have extensive experience of working with companies in the same sectors as National Grid operates, 
and this experience was relevant to the discussion about where fraud risks may arise. The discussion was also carried out across the engagement team  
specific to the potential fraud implications of COVID-19 in relation to added financial pressures as well as in relation to increases in remote working.

In common with all audits under ISAs (UK), we are also required to identify management override as a significant risk and to perform specific procedures to 
respond to that risk.

We also obtained an understanding of the legal and regulatory frameworks that the Group operates in, focusing on provisions of those laws and regulations that 
had a direct effect on the determination of material amounts and disclosures in the financial statements. The key laws and regulations we considered in this context 
included the UK Companies Act 2006, the UK Listing Rules, pensions and tax legislation, US Securities Exchange Act 1934 and relevant SEC regulations, as well 
as laws and regulations prevailing in each country in which we identified a full scope component. In addition, compliance with terms of the Group’s operating 
licence and environmental regulations were fundamental to the Group’s operations. 

In addition, we considered provisions of other laws and regulations that do not have a direct effect on the financial statements but compliance with which may be 
fundamental to the Group’s ability to operate or to avoid a material penalty. These included the Group’s operating licences and environmental regulations.

11.2. Audit response to risks identified

As a result of performing the above, we did not identify any key audit matters related to the potential risk of fraud or non-compliance with laws and regulations. 
Our procedures to respond to risks identified included the following:
• reviewing the financial statement disclosures and testing to supporting documentation to assess compliance with provisions of relevant laws and regulations 

described as having a direct effect on the financial statements;

• enquiring of management, the Audit Committee and in-house legal counsel concerning actual and potential litigation and claims;
• performing analytical procedures to identify any unusual or unexpected relationships that may indicate risks of material misstatement due to fraud;
• reading minutes of meetings of those charged with governance, reviewing internal audit reports and reviewing correspondence with relevant regulatory authorities; 
• in addressing the risk of fraud through management override of controls, testing the appropriateness of journal entries and other adjustments; assessing whether 
the judgements made in making accounting estimates are indicative of a potential bias; and evaluating the business rationale of any significant transactions that 
are unusual or outside the normal course of business.

We also communicated relevant identified laws and regulations and potential fraud risks to all engagement team members including internal specialists and 
significant component audit teams, and remained alert to any indications of fraud or non-compliance with laws and regulations throughout the audit.

12.  Opinions on other matters prescribed by the Companies 

Act 2006

In our opinion the part of the directors’ remuneration report to  
be audited has been properly prepared in accordance with the 
Companies Act 2006.

In our opinion, based on the work undertaken in the course of  
the audit:

•   the information given in the strategic report and the directors’ 
report for the financial year for which the financial statements  
are prepared is consistent with the financial statements; and

•   the strategic report and the directors’ report have been prepared

National Grid plc Annual Report and Accounts 2019/20Financial StatementsNotes to the consolidated financial statements 
– analysis of items in the primary statements

1. Basis of preparation and recent accounting developments

Accounting policies describe our approach to recognising and measuring transactions and balances in the year. The accounting policies applicable 
across the financial statements are shown below, whereas accounting policies that are specific to a component of the financial statements have 
been incorporated into the relevant note.

This section also shows areas of judgement and key sources of estimation uncertainty in these financial statements. In addition, we have 
summarised new International Accounting Standards Board (IASB) and EU endorsed accounting standards, amendments and interpretations  
and whether these are effective for this year end or in later years, explaining how significant changes are expected to affect our reported results.

National Grid’s principal activities involve the transmission and 
distribution of electricity and gas in Great Britain and northeastern  
US. The Company is a public limited liability company incorporated  
and domiciled in England and Wales, with its registered office at  
1–3 Strand, London WC2N 5EH.

The Company, National Grid plc, which is the ultimate parent of the 
Group, has its primary listing on the London Stock Exchange and  
is also quoted on the New York Stock Exchange.

These consolidated financial statements were approved for issue by 
the Board on 17 June 2020.

These consolidated financial statements have been prepared in 
accordance with International Accounting Standards (IAS) and 
International Financial Reporting Standards (IFRS) and related 
interpretations as issued by the IASB and IFRS as adopted by the EU. 
They are prepared on the basis of all IFRS accounting standards and 
interpretations that are mandatory for periods ended 31 March 2020 and 
in accordance with the Companies Act 2006 applicable to companies 
reporting under IFRS and Article 4 of the EU IAS Regulation. The 
comparative financial information has also been prepared on this basis.

The consolidated financial statements have been prepared on a 
historical cost basis, except for the recording of pension assets  
and liabilities, the revaluation of derivative financial instruments and 
certain commodity contracts and certain financial assets and liabilities 
measured at fair value.

These consolidated financial statements are presented in pounds 
sterling, which is also the functional currency of the Company.

The notes to the financial statements have been prepared on a 
continuing basis unless otherwise stated.

Our income statement and segmental analysis separately identify 
financial results before and after exceptional items and remeasurements. 
We continue to use a columnar presentation as we consider it improves 
the clarity of the presentation, and is consistent with the way that 
financial performance is measured by management and reported to  
the Board and Executive Committee, and assists users of the financial 
statements to understand the results. The inclusion of total profit for  
the period from continuing operations before exceptional items and 
remeasurements forms part of the incentive target set annually for 
remunerating certain Executive Directors and accordingly we believe it  
is important for users of the financial statements to understand how this 
compares to our results on a statutory basis and period on period.

A. Going concern
As at the date of approving these financial statements, the impact of 
COVID-19 on the Group’s operations is continually being assessed and 
subject to rapid change. The Directors have assessed the principal risks 
discussed on pages 24 – 25, including by modelling both a base case 
and a reasonable worst case scenario. The reasonable worst-case 
scenario covers the cash flow impact associated with an extended 
lockdown for a period of 12 months across both the UK and US.  
The main cash flow impacts identified in the reasonable worst-case 
scenario are:

•  a significant reduction in cash collections over an extended 

12-month period driven by lower customer demand and increased 
bad debt in our US businesses;

•  additional working capital required to fund payment term extensions 
and charge deferrals in the UK electricity market, intended to help 
customers and end-user consumers;

•  one-off increases in other costs such as cleaning, safety equipment 

and IT; offset by
•  a reduction in non-essential capital expenditure across the 

Group driven by increased absenteeism, supply chain issues  
and difficulty in accessing sites; and

•  a reduction in discretionary spend across all areas (e.g. 

recruitment, travel and consultancy spend).

As part of their analysis, the Board also considered the following 
potential levers at their discretion to improve the position identified by  
the reasonable worst-case scenario in the event that the debt capital 
markets are not accessible:

•  further significant changes in the phasing of the Group’s capital 

programme with elements of non-essential works and programmes 
delayed beyond June 2021;

•  a number of further reductions in operating expenditure across  
the Group primarily related to workforce cost reductions in both  
the UK and the US; and

•  the payment of dividends to shareholders.

Having considered the reasonable worst-scenario and further levers at 
the Board’s discretion, the Group continues to have headroom against 
the Group’s committed facilities identified in note 33 to the financial 
statements.

In addition to the above, the ability to raise new financing was separately 
included in the analysis and the Directors noted the £0.9 billion debt 
issuances completed in April 2020 (disclosed in note 21 to the financial 
statements) as evidence of the Group’s ability to continue to have access 
to the debt capital markets if needed. Other factors considered by the 
Board as part of their Going Concern assessment included the potential 
impact of Brexit trade talks, the Group’s various ongoing rate case 
determinations in the UK and US alongside inherent uncertainties in 
cash flow forecasts (such as the impact of storms in our US business).

Based on the above, the Directors have concluded the Group is well 
placed to manage its financing and other business risks satisfactorily, 
and have a reasonable expectation that the Group will have adequate 
resources to continue in operation for at least 12 months from the 
signing date of these consolidated financial statements. They therefore 
consider it appropriate to adopt the going concern basis of accounting 
in preparing the financial statements.

National Grid plc Annual Report and Accounts 2019/20Financial Statements | Notes to the consolidated financial statementsNotes to the consolidated financial statements 
– analysis of items in the primary statements continued

1. Basis of preparation and recent accounting developments continued

B. Basis of consolidation
The consolidated financial statements incorporate the results, assets 
and liabilities of the Company and its subsidiaries, together with a share 
of the results, assets and liabilities of joint operations. 

A subsidiary is defined as an entity controlled by the Group. Control is 
achieved where the Group is exposed to, or has the rights to, variable 
returns from its involvement with the entity and has the power to affect 
those returns through its power over the entity.

E. Areas of judgement and key sources of estimation 
uncertainty 
The preparation of financial statements requires management to make 
estimates and assumptions that affect the reported amounts of assets 
and liabilities, disclosures of contingent assets and liabilities, and the 
reported amounts of revenue and expenses during the reporting period. 
Actual results could differ from these estimates. Information about such 
judgements and estimations is in the notes to the financial statements, 
and the key areas are summarised below.

The Group accounts for joint ventures and associates using the equity 
method of accounting, where the investment is carried at cost plus 
post-acquisition changes in the share of net assets of the joint venture  
or associate, less any provision for impairment. Losses in excess of the 
consolidated interest in joint ventures and associates are not recognised, 
except where the Company or its subsidiaries have made a commitment 
to make good those losses.

Where necessary, adjustments are made to bring the accounting 
policies used in the individual financial statements of the Company, 
subsidiaries, joint operations, joint ventures and associates into line  
with those used by the Group in its consolidated financial statements 
under IFRS. Intercompany transactions are eliminated.

The results of subsidiaries, joint operations, joint ventures and 
associates acquired or disposed of during the year are included  
in the consolidated income statement from the effective date of 
acquisition or up to the effective date of disposal, as appropriate.

Acquisitions are accounted for using the acquisition method, where  
the purchase price is allocated to the identifiable assets acquired and 
liabilities assumed on a fair value basis and the remainder recognised  
as goodwill.

C. Treatment of interests in Quadgas HoldCo Limited 
(Quadgas) – discontinued operations and held for sale
At the end of June 2019, we completed the disposal of our retained  
39% interest in the UK Gas Distribution business (held through 
Quadgas) that was classified as held for sale. We have treated the 
results and cash flows of Quadgas as a discontinued operation in  
the consolidated income statement and consolidated cash flow 
statement. Refer to note 10 for further details.

D. Foreign currencies
Transactions in currencies other than the functional currency of  
the Company or subsidiary concerned are recorded at the rates of 
exchange prevailing on the dates of the transactions. At each reporting 
date, monetary assets and liabilities that are denominated in foreign 
currencies are retranslated at closing exchange rates. Non-monetary 
assets are not retranslated unless they are carried at fair value.

Gains and losses arising on the retranslation of monetary assets 
and liabilities are included in the income statement, except where 
the application of hedge accounting requires inclusion in other 
comprehensive income (see note 32(e)).

On consolidation, the assets and liabilities of operations that have a 
functional currency different from the Company’s functional currency 
of pounds sterling, principally our US operations that have a functional 
currency of US dollars, are translated at exchange rates prevailing at the 
reporting date. Income and expense items are translated at the average 
exchange rates for the period where these do not differ materially from 
rates at the date of the transaction. Exchange differences arising are 
recognised in other comprehensive income and transferred to the 
consolidated translation reserve within other equity reserves (see note 28).

Areas of judgement that have the most significant effect on the 
amounts recognised in the financial statements are as follows: 
•  categorisation of certain items as exceptional items or 

remeasurements and the definition of adjusted earnings (see notes 5 
and 8). In applying the Group’s exceptional items framework, we 
have considered a number of key matters, as detailed in note 5; 
•  the judgement that notwithstanding legislation enacted and targets 
established during the year ended 31 March 2020 committing  
the UK, New York State and Massachusetts to achieving net  
zero greenhouse gas emissions by 2050, these do not trigger  
a reassessment of the remaining useful economic lives of our  
gas network assets (see estimate below and note 13); and 

•  following the legal separation of the Electricity System Operator  

on 1 April 2019, we concluded that the Electricity System Operator 
acts as an agent in respect of certain Transmission Network Use  
of Service revenues, principally those collected on behalf of the 
Scottish and Offshore transmission operators, as detailed in note 3. 

Key sources of estimation uncertainty that have a significant risk 
of causing a material adjustment to the carrying amounts of assets 
and liabilities within the next financial year are as follows: 
•  the valuation of liabilities for pensions and other post-retirement 

benefits (see note 25); and 

•  the cash flows applied in determining the environmental provisions, 

in particular relating to three US Superfund sites (see note 26). 

In light of the current ongoing impact of the COVID-19 pandemic, 
valuations of certain assets and liabilities are necessarily more 
subjective. In particular, two further areas of estimation uncertainty 
impacting the Group’s position as at 31 March 2020 have been 
identified: 

•  the valuation of certain pension assets, in particular unquoted 
equities, properties and diversified alternatives, in light of the  
volatile economic markets (see note 25); and 

•  the recoverability of customer receivables, particularly in relation  

to US retail customers, in light of the suspension of debt collection 
activities and customer termination activities (see note 19). 

In addition, we also highlight the estimates made regarding the useful 
economic lives of our gas network assets due to the length over which 
they are being depreciated, the potential for new and evolving 
technologies over that period, and the range of potential pathways for 
meeting net zero targets (see note 13 for details and sensitivity analysis). 

In order to illustrate the impact that changes in assumptions for  
the valuation of pension assets and liabilities and cash flows for 
environmental provisions could have on our results and financial 
position, we have included sensitivity analyses in note 35. Information  
on what we believe a reasonably possible range of outcomes to be  
on recoverability of customer receivables are included in note 19.

H. New IFRS accounting standards and interpretations not 
yet adopted
The following new accounting standards and amendments to existing 
standards have been issued but are not yet effective or have not yet 
been endorsed by the EU: 
•  IFRS 17 ‘Insurance Contracts’; 
•  Amendments to IFRS 3 ‘Business Combinations’; 
•  Amendments to the References to the Conceptual Framework; 
•  Amendments to IAS 1 and IAS 8: Definition of material; and 
•  Amendments to IAS 1 ‘Presentation of Financial Statements’. 

Effective dates remain subject to the EU endorsement process.

The Group is currently assessing the impact of the above standards, 
but they are not expected to have a material impact. The Group has 
not adopted any other standard, amendment or interpretation that  
has been issued but is not yet effective.

F. Accounting policy choices
IFRS provides certain options available within accounting standards. 
Choices we have made, and continue to make, include the following:
•  Presentational formats: we use the nature of expense method for our 
income statement and aggregate our statement of financial position 
to net assets and total equity. In the income statement, we present 
subtotals of total operating profit, profit before tax and profit after  
tax from continuing operations, together with additional subtotals 
excluding exceptional items and remeasurements as a result of the 
three columnar presentation described earlier. Exceptional items 
and remeasurements are presented in a separate column on the 
face of the income statement.

•  Financial instruments: we normally opt to apply hedge accounting 
in most circumstances where this is permitted (see note 32(e)).

•  Cash flow statement: Following a review in the year, we have 
changed our accounting policy in relation to the presentation  
of derivatives in the cash flow statement, which has resulted in 
£412 million of cash outflows for 2019 and £330 million of cash 
inflows from 2018 to be presented as investing activities rather  
than financing activities. The reclassified cash flows are in relation  
to derivatives associated with our net investment hedges, and given 
they are designated in a hedge relationship, the Group has decided 
to present them together with the underlying hedged item rather 
than as part of our overall financing activities.

G. New IFRS accounting standards and interpretations 
effective for the year ended 31 March 2020 
The Group adopted IFRS 16 ‘Leases’ with effect from 1 April 2019. 
We have applied the modified retrospective approach permitted in 
the standard whereby prior year comparatives have not been restated 
on adoption. Instead, any cumulative transition adjustments are reflected 
through reserves. Refer to note 37 for full details of the impact and 
transition adjustments arising on adoption. 

The UK’s Financial Conduct Authority announced that LIBOR will cease 
to exist by the end of 2021, and will be replaced by alternative reference 
rates. In September 2019, the IASB amended IFRS 9 and IFRS 7 by 
issuing Interest Rate Benchmark Reform, which provides exceptions  
to specific hedge accounting requirements to ensure that hedging 
relationships are not considered to be modified as a result of the change 
in the reference rate. The amendments were endorsed in January 2020 
for adoption in the EU. The Group early-adopted these changes to IFRS 
9 and IFRS 7 with effect from 1 April 2019. There were no transition 
adjustments on adoption. Refer to note 32(e) for further details of the 
impact in the current period.

The Group has also adopted the following amendments to standards, 
which have had no material impact on the Group’s results or financial 
statement disclosure: 
•  IFRIC 23 ‘Uncertainty over Income Tax Treatments’; 
•  Amendments to IAS 28 ‘Investments in Associates – Long-term 

Interests in Associates and Joint Ventures’; 

•  Annual Improvements to IFRS Standards 2015–2017 Cycle; and 
•  Amendments to IAS 19 ‘Employee Benefits’.

2. Segmental analysis 

This note sets out the financial performance for the year split into the different parts of the business (operating segments). The performance of 
these operating segments is monitored and managed on a day-to-day basis. Revenue and the results of the business are analysed by operating 
segment, based on the information the Board of Directors uses internally for the purposes of evaluating the performance of each operating 
segment and determining resource allocation between them. The Board is National Grid’s chief operating decision maker (as defined by IFRS 8 
‘Operating Segments’) and assesses the profitability of operations principally on the basis of operating profit before exceptional items and 
remeasurements (see note 5). As a matter of course, the Board also considers profitability by segment, excluding the effect of timing. However,  
the measure of profit disclosed in this note is operating profit before exceptional items and remeasurements as this is the measure that is most 
consistent with the IFRS results reported within these financial statements.

The results of our three principal businesses are reported to the Board of Directors and are treated as reportable operating segments. The following 
table describes the main activities for each reportable operating segment:

UK Electricity Transmission

The high-voltage electricity transmission networks in England and Wales and independent Great Britain system operator.

UK Gas Transmission

The high-pressure gas transmission networks in Great Britain and system operator in Great Britain.

US Regulated

Gas distribution networks, electricity distribution networks and high-voltage electricity transmission networks in New 
York and New England and electricity generation facilities in New York.

The UK Electricity Transmission segment also includes the independent Electricity System Operator (ESO). Although there is a separate governance 
structure (including a separate Executive Committee), the Board receives financial information on an aggregated UK Electricity Transmission basis, 
which includes the results of the ESO, and accordingly the ESO is included within the reportable segment. 

National Grid Ventures (NGV) is our only other operating segment. It does not currently meet the thresholds set out in IFRS 8 to be identified as 
a separate reportable segment and therefore its results are not required to be separately presented. Instead, NGV’s results are reported alongside 
the results of all other operating businesses on an aggregated basis as “NGV and Other”, with certain additional disclosure included in footnotes. 

NGV represents our key strategic growth area outside our regulated core business in competitive markets across the US and the UK. The business 
comprises all commercial operations in metering, LNG at the Isle of Grain in the UK, electricity interconnectors and our new investments in Geronimo 
Energy LLC (Geronimo) and Emerald Energy Venture LLC (Emerald). Geronimo is a developer of wind and solar generation based in Minneapolis in 
the US. The acquisition is National Grid’s first ownership stake in wind generation and an expansion of our activities in solar generation. 

Other activities that do not form part of any of the segments in the above table or NGV primarily relate to our UK property business together  
with insurance and corporate activities in the UK and US and the Group’s investments in technology and innovation companies through  
National Grid Partners. 

The segmental information is presented in relation to continuing operations only and therefore does not include the profits and losses relating to our 
interest in Quadgas for any period presented (see note 10). 

(a) Revenue
Revenue primarily represents the sales value derived from the generation, transmission and distribution of energy, together with the sales value 
derived from the provision of other services to customers. Refer to note 3 for further details. 

Sales between operating segments are priced considering the regulatory and legal requirements to which the businesses are subject. The analysis 
of revenue by geographical area is on the basis of destination. There are no material sales between the UK and US geographical areas.

3. Revenue

Revenue arises in the course of ordinary activities and principally comprises:
•  transmission services;
•  distribution services; and
•  generation services.

Transmission services, distribution services and certain other services (excluding rental income but including metering) fall within the scope of IFRS 
15 ‘Revenue from Contracts with Customers’, whereas generation services (which solely relate to the contract with the Long Island Power Authority 
(LIPA) in the US) are accounted for under the leasing standard as rental income, also presented within revenue. Revenue is measured based on the 
consideration specified in a contract with a customer and excludes amounts collected on behalf of third parties and value added tax. The Group 
recognises revenue when it transfers control over a product or service to a customer.

IFRS 15 was adopted in the prior year and applied prospectively from 1 April 2018. Therefore, the analysis below is only provided for the current 
period and the immediate comparative period. Below, we include a description of principal activities, by reportable segment, from which the Group 
generates its revenue. For more detailed information about our segments, see note 2.

(a) UK Electricity Transmission
The UK Electricity Transmission segment principally generates revenue by providing electricity transmission services (both as transmission owner  
in England and Wales and system operator in Great Britain). Our business operates as a monopoly regulated by Ofgem, which has established  
price control mechanisms that set the amount of annual allowed returns our business can earn (along with the Scottish and Offshore transmission 
operators amongst others). The IFRS revenues we record are principally a function of volumes and price. Price is determined prior to our financial 
year-end with reference to the regulated allowed returns and estimated annual volumes. Where revenue received or receivable exceeds the 
maximum amount permitted by regulatory agreement, adjustments will be made to future prices to reflect this over-recovery. No liability is 
recognised, as such an adjustment to future prices relates to the provision of future services. Similarly, no asset is recognised where a regulatory 
agreement permits adjustments to be made to future prices in respect of an under-recovery. As part of our regulatory agreements we are entitled  
to recover certain costs directly from customers (pass-through costs). These amounts are included in the overall calculation of allowed revenue as 
stipulated by regulatory agreements. 

The System Operator earns revenue for balancing supply and demand of electricity on the transmission system, where it acts as principal. Revenue 
is recognised as the service is provided. The System Operator also collects revenues on behalf of transmission operators, principally NGET and the 
Scottish and Offshore transmission operators, from users who connect to or use the transmission system. However, these amounts are paid to the 
transmission operators before the System Operator has collected payment from the users (electricity suppliers) and therefore the System Operator 
does hold some exposure to credit losses with electricity suppliers. The System Operator must set the charges paid by electricity suppliers by 
reference to the price control mechanism described above. That mechanism does not grant the System Operator with discretion to deviate from  
that mechanism. The transmission operators own and maintain the electricity network and receive direct feedback from electricity suppliers on  
the quality of the network they provide. There is a judgement about whether the System Operator acts as a principal or agent in respect of the 
transmission network revenues collected on behalf of the Scottish and Offshore transmission operators (as set out in note 1). We have concluded 
that it acts as an agent in respect of these transmission revenues and therefore records the attributable revenue net of operating costs. 

The transmission of high-voltage electricity encompasses the following principal services: 

•  the supply of high-voltage electricity (including both transmission and system operator charges); and 
•  construction work (principally for connections). 

For the supply of high-voltage electricity, revenue is recognised based on capacity and volumes. Our performance obligation is satisfied over time as 
our customers make use of our network. We bill monthly in arrears and our payment terms are up to 60 days. 

For construction work relating to connections, customers can either pay over the useful life of the connection or upfront. Revenue is recognised over 
time, as we provide access to our network, and where the customer pays upfront, revenues are deferred and released over the life of the connection. 

For other construction where there is no consideration for any future services, for example diversions (being the re-routing of network assets at our 
customers’ request), revenues are recognised as the construction work is completed. 

(b) UK Gas Transmission
The UK Gas Transmission segment of the Group principally generates revenue by providing gas transmission services to our customers (both as 
transmission owner and as system operator) in Great Britain. Similar to our UK Electricity Transmission business, our business operates as a 
monopoly regulated by Ofgem. The price control mechanism in place that determines our annual allowances is also similar, as is the way in which 
revenue is recorded. 

The transmission of gas encompasses the following principal services: 

•  the supply of high-pressure gas (including both transmission and system operator charges); and 
•  construction work (principally for connections). 

For the supply of high-pressure gas, revenue is recognised based on capacity and volumes. Our performance obligation is satisfied over time as our 
customers make use of our network, and we bill monthly in arrears with payment terms of up to 45 days. 

For construction work relating to connections, customers pay for the connection upfront. Revenue is recognised over time, as we provide access to 
our network. Where revenues are received upfront, they are deferred and released over the life of the connection. 

For other construction where there is no consideration for any future services (such as diversions), revenues are recognised when the construction 
work is completed.

(c) US Regulated
The US Regulated segment of the Group principally generates revenue by providing gas and electricity distribution services in New York and  
New England, high voltage electricity transmission services in New York and New England, and electricity generation in New York. 

Distribution services
Provision of gas and electricity distribution services in New York and New England. This comprises the following principal services: 
•  Gas and electricity distribution: revenue is recognised based on usage by customers (over time) and billed monthly. Payment terms  

are 30 days; and 

•  Connections: revenue is recognised over time, as we provide access to our network. Where payments are made upfront, they are  

deferred over the life of the asset. 

Transmission services
Provision of electricity transmission services to customers and operation of electricity transmission facilities. Our principal services are: 
•  Electricity transmission: revenue is recognised based on usage by customers (over time) and billed monthly. Payment terms are 30 days; and 
•  Connections: revenue is recognised over time, as we provide access to our network. Where payments are made upfront, they are deferred  

over the life of the asset. 

Electricity generation
Provision of energy services and supply capacity to produce energy for the use of customers of the Long Island Power Authority (LIPA) through a 
power supply agreement. This falls within the scope of the leasing standard, where we act as lessor with rental income being recorded as other 
income, which forms part of total revenue. 

(d) NGV and Other 
NGV and Other includes electricity interconnectors, LNG at the Isle of Grain, Geronimo, metering, sales from our UK property business, rental 
income and insurance. 

The Group recognises revenue from transmission services through interconnectors and LNG at the Isle of Grain by means of customers’ use of 
capacity and volumes. Revenue is recognised over time and is billed monthly. Payment terms are up to 30 days. 

Other revenue in the scope of IFRS 15 principally includes revenues from our UK metering business and sales of renewables projects from Geronimo 
to Emerald (see note 38). Revenue is recognised as it is earned. In the case of the UK metering business, revenue is billed monthly and payment 
terms are up to 30 days. 

Other revenue, recognised in accordance with standards other than IFRS 15, includes property sales by our UK commercial property business 
(including sales to our St William joint venture) and rental income. Property sales are recorded at a point in time (when the sale is legally completed) 
and rental income is recorded over time. 

(e) Disaggregation of revenue
In the following tables, revenue is disaggregated by primary geographical market and major service lines. The table reconciles disaggregated 
revenue with the Group’s reportable segments (see note 2).

Revenue to be recognised in future periods, presented as contract liabilities of £1,158 million (2019: £994 million) (see note 23), relates to 
contributions in aid of construction. Revenue is recognised over the life of the asset. The asset lives for connections in UK Electricity Transmission, 
UK Gas Transmission, NGV and US Regulated are 40 years, 36 years (to 2055), 15 years and up to 51 years respectively. The weighted average 
amortisation period is 18 years. 

Future revenues in relation to unfulfilled performance obligations not yet received in cash amount to £3.1 billion (2019: £3.5 billion). £1.5 billion  
(2019: £1.6 billion) relates to connection contracts in UK Electricity Transmission which will be recognised as revenue over 29 years and £1.5 billion 
(2019: £1.8 billion) relates to revenues to be earned under Grain LNG contracts until 2029. The remaining amount will be recognised as revenue  
over 5 years. 

The amount of revenue recognised for the year ended 31 March 2020 from performance obligations satisfied (or partially satisfied) in previous 
periods, mainly due to the changes in the estimate of the stage of completion, is £nil (2019: £nil).

National Grid plc Annual Report and Accounts 2019/20Financial Statements5. Exceptional items and remeasurements

To monitor our financial performance, we use a profit measure that excludes certain income and expenses. We call that measure ‘business 
performance’ or ‘adjusted profit’. Business performance (which excludes exceptional items and remeasurements as defined below) is used by 
management to monitor financial performance as it is considered that it aids the comparability of our reported financial performance from year to 
year. We exclude items from business performance because, if included, these items could distort understanding of our performance for the year 
and the comparability between periods. This note analyses these items, which are included in our results for the year but are excluded from 
business performance.

5. Exceptional items and remeasurements continued
Exceptional items
Management uses an exceptional items framework that has been discussed and approved by the Audit Committee. This follows a three-step 
process which considers the nature of the event, the financial materiality involved and any particular facts and circumstances. In considering the 
nature of the event, management focuses on whether the event is within the Group’s control and how frequently such an event typically occurs.  
In determining the facts and circumstances, management considers factors such as ensuring consistent treatment between favourable and 
unfavourable transactions, the precedent for similar items, the number of periods over which costs will be spread or gains earned, and the 
commercial context for the particular transaction. 

Items of income or expense that are considered by management for designation as exceptional items include significant restructurings, write-downs 
or impairments of non-current assets, significant changes in environmental or decommissioning provisions, integration of acquired businesses, gains 
or losses on disposals of businesses or investments and significant debt redemption costs as a consequence of transactions such as significant 
disposals or issues of equity, and the related tax, as well as deferred tax arising on changes to corporation tax rates. 

Costs arising from restructuring programmes include redundancy costs. Redundancy costs are charged to the consolidated income statement in the 
year in which a commitment is made to incur the costs and the main features of the restructuring plan have been announced to affected employees. 

Set out below are details of the transactions against which we have considered the application of our exceptional items framework in each of the 
years for which results are presented. 

2020 
We concluded that the increase in costs associated with the changes in our environmental provisions (£402 million) and the additional deferred tax 
charge reflecting the impact of the remeasurement of the Group’s deferred tax liabilities as a result of a change in the substantively enacted UK 
corporation tax rate (£192 million) meet the criteria to be classified as exceptional. 

A further £10 million of COVID-19 related costs incurred in the year have similarly not been classified as exceptional in view of the quantum involved 
and all costs associated with the settlement reached with the State of New York in respect of the Downstate New York Gas Moratorium have also 
been treated as part of adjusted profit. 

Environmental charges: In the US, the most significant component of our £1.9 billion environmental provision relates to several Superfund sites,  
and arose from former manufacturing gas plant facilities, formerly owned or operated by the Group or its predecessor companies. 

The sites are subject to both State and Federal law in the US. Under Federal and State Superfund laws, potential liability for the historical 
contamination may be imposed on responsible parties jointly and severally, without regard to fault, even if the activities were lawful when they 
occurred. The provisions and the Group’s share of estimated costs are re-evaluated at each reporting period. As a result of notices issued by 
governmental authorities and newly developed cost estimates prepared by third-party engineers, we have re-evaluated our estimates of total  
costs and cost sharing allocations borne by the Company, and accordingly have increased our provision by £326 million. Under the terms of our rate 
plans, we are entitled to recovery of environmental clean-up costs from rate payers, but under IFRS no asset can be recognised for this recovery. 

Also included in the total environmental charge is the £76 million impact of the change in the real discount rate applied to the environmental 
provisions across the Group, of which £66 million relates to the US and £10 million to the UK. Given the substantial and sustained change in  
gilts and corporate bond yields, we concluded it was appropriate to reduce the real discount rate from 1% to 0.5%. The weighted average  
remaining duration of our cash flows is now around 10 years. 

2019 
In assessing certain items of income and expenditure against our exceptional items framework, we concluded that the costs associated with the 
Massachusetts Gas labour dispute (£283 million), our cost efficiency and restructuring programme (£204 million) and impairments relating to two 
nuclear connection cancellations (£137 million) should be treated as exceptional (as described further below). 

We also considered whether the £95 million income from two legal settlements received in the period should be classified as exceptional. However, 
we concluded it was appropriate to recognise the income in earnings before exceptional items (within NGV and Other), in line with the treatment of 
the original costs. 

Cost efficiency and restructuring programmes: Our UK and US businesses incurred restructuring charges as we reviewed organisational 
structures, operational activities and relevant roles and responsibilities to ensure we are able to operate more efficiently and to continue to drive 
outperformance for customers and shareholders. The cash outflow for the year was £93 million. 

Massachusetts Gas labour dispute: Between June 2018 and January 2019, National Grid implemented a workforce contingency plan across  
its Massachusetts Gas business following the expiration of contracts for the 1,250 members of the existing workforce. The net incremental cost of  
the experienced contractors working alongside supervisors and workers from other areas of the business was £283 million, reflecting the financial 
performance of the US regulated business had the workforce contingency plan not been implemented. The total cash outflow related to the labour 
dispute was £320 million for the year. 

Impairment of nuclear connection development costs: In 2018, Toshiba announced the cancellation of its NuGen project to build a new 
nuclear power station at Moorside in Cumbria, and NuGen terminated its connection agreement with UK Electricity Transmission. In February 2019, 
Hitachi terminated its connection agreements in respect of its Horizon projects at Wylfa and Oldbury. As there was no realistic prospect of these 
schemes continuing in their present form, we concluded that it was appropriate to impair the assets we had been developing for over 10 years.  
After deducting cash inflows relating to termination fees received of £13 million, the net impairment charge was £137 million. 

2018 
Final settlement of LIPA MSA transition: During the year, the Group reached an agreement with LIPA on an amount in final settlement of 
receivables and payables that arose following the cessation of the Management Services Agreement with LIPA in December 2013. The settlement 
resulted in a gain of £26 million, which was recorded as exceptional, consistent with the treatment of gains and losses on the original transaction.

National Grid plc Annual Report and Accounts 2019/20Financial Statements5. Exceptional items and remeasurements continued
Remeasurements
Remeasurements comprise unrealised gains or losses recorded in the consolidated income statement arising from changes in the fair value  
of certain of our financial assets and liabilities accounted for at fair value through profit and loss (FVTPL). These assets and liabilities include 
commodity contract derivatives and financing derivatives to the extent that hedge accounting is not achieved or is not effective. 

The unrealised gains or losses reported in profit and loss on certain additional assets and liabilities now treated at FVTPL are also classified within 
remeasurements. These relate to financial assets (which fail the ‘solely payments of principal and interest test’ under IFRS 9), the money market fund 
investments used by Group Treasury for cash management purposes and certain financial liabilities which we elected to designate at FVTPL. In all 
cases, these fair values increase or decrease because of changes in foreign exchange, commodity or other financial indices over which we have  
no control. 

We report unrealised gains or losses relating to certain discrete classes of financial assets accounted for at FVTPL within business performance. 
These comprise our portfolio of investments made by National Grid Partners, our investment in Sunrun Neptune 2016 LLC and the contingent 
consideration arising on the acquisition of Geronimo (all within NGV and Other). The performance of these assets (including changes in fair value)  
are included in our assessment of business performance for the relevant business units. 

Remeasurements excluded from business performance are made up of the following categories: 
i.  Net gains/(losses) on commodity contract derivatives represent mark-to-market movements on certain physical and financial commodity 

contract obligations in the US. These contracts primarily relate to the forward purchase of energy for supply to customers, or to the economic 
hedging thereof, that are required to be measured at fair value and that do not qualify for hedge accounting. Under the existing rate plans in  
the US, commodity costs are recoverable from customers although the timing of recovery may differ from the pattern of costs incurred; 

ii.  Net gains/(losses) on financing derivative financial instruments comprise gains and losses arising on derivative financial instruments reported  
in the consolidated income statement in relation to risk management of interest rate and foreign exchange exposures. These exclude gains  
and losses for which hedge accounting has been effective, and have been recognised directly in the consolidated statement of other 
comprehensive income or are offset by adjustments to the carrying value of debt (see notes 17 and 32); 

iii. Net gains/(losses) on financial assets measured at FVTPL comprise gains and losses on the investment funds held by our insurance captives 

which are categorised as FVTPL (see note 15); 

iv. Net gains/(losses) on financial liabilities measured at FVTPL comprises the change in the fair value (excluding changes due to own credit risk)  

of a financial liability that was designated at FVTPL on transition to IFRS 9 to reduce a measurement mismatch (see note 21); and 

v. Unrealised net gains/(losses) on derivatives and other financial instruments within our joint ventures and associates. 

Items included within tax
2020
The Finance Act 2016, which was enacted on 15 September 2016, reduced the main UK corporation tax rate to 17% with effect from 1 April 2020. 
Deferred tax balances were calculated at this rate for the years ended 31 March 2017 to 2019. On 17 March 2020, the UK Government utilised the 
Provisional Collection of Taxes Act 1968 to substantively enact a reversal of the reduction in the main UK corporation tax rate to 17% with effect from 
1 April 2020, resulting in the rate remaining at 19%. Deferred taxes at the reporting date have been measured using enacted tax rates and reflected 
in these financial statements, resulting in a £192 million deferred tax charge, principally due to the remeasurement of deferred tax liabilities. The 
treatment of this charge as exceptional is consistent with the treatment for the year ended 31 March 2017 when the original reduction in the tax rate 
was substantively enacted, resulting in the recognition of an exceptional tax credit of £94 million. 

2018
The Tax Cuts and Jobs Act (Tax Reform), which was enacted on 22 December 2017, reduced the US corporate tax rate from 35% to 21% with effect 
from 1 January 2018. Deferred taxes at the reporting date have been measured using these enacted tax rates. This resulted in a one-off deferred tax 
credit in the year ended 31 March 2018. However, as described in note 11, we expect the overall impact of Tax Reform to be economically neutral for 
the Group.

6. Finance income and costs

This note details the interest income generated by our financial assets and interest expense incurred on our financial liabilities, primarily our 
financing portfolio (including our financing derivatives). It also includes the net interest on our pensions and other post-retirement assets. In 
reporting business performance, we adjust net financing costs to exclude any net gains or losses on financial instruments included in 
remeasurements (see note 5). In addition, where debt redemptions relate to exceptional transactions they are typically treated as exceptional.

The Group adopted IFRS 9 with effect from 1 April 2018. The comparatives for 2018 were not required to be restated and were accounted for in 
accordance with IAS 39. Following the adoption of IFRS 9, finance income and costs remeasurements include unrealised gains and losses on certain 
assets and liabilities now treated at FVTPL. The interest income, dividends and interest expense on these items are included in finance income and 
finance costs before remeasurements, respectively.

2.   Interest on funding attributable to assets in the course of construction in the current year was capitalised at a rate of 3.6% (2019: 3.9%; 2018: 4.1%). In the UK, capitalised interest qualifies 
for a current year tax deduction with tax relief claimed of £15 million (2019: £19 million; 2018: £20 million). In the US, capitalised interest is added to the cost of plant and qualifies for tax 
depreciation allowances. 

3.   Includes a net foreign exchange gain on financing activities of £66 million (2019: £264 million gain; 2018: £314 million loss) offset by foreign exchange losses and gains on financing 

derivatives measured at fair value.

National Grid plc Annual Report and Accounts 2019/20Financial Statements7. Tax

Tax is payable in the territories where we operate, mainly the UK and the US. This note gives further details of the total tax charge and tax liabilities, 
including current and deferred tax. The current tax charge is the tax payable on this year’s taxable profits. Deferred tax is an accounting 
adjustment to provide for tax that is expected to arise in the future due to differences in the accounting and tax bases.

The tax charge for the period is recognised in the income statement, the statement of comprehensive income or directly in equity, according to  
the accounting treatment of the related transaction. The tax charge comprises both current and deferred tax.

Current tax assets and liabilities are measured at the amounts expected to be recovered from or paid to the tax authorities. The tax rates and tax 
laws used to compute the amounts are those that have been enacted or substantively enacted by the reporting date.

The Group operates internationally in territories with different and complex tax codes. Management exercises judgement in relation to the level  
of provision required for uncertain tax outcomes. There are a number of tax positions not yet agreed with the tax authorities where different 
interpretations of legislation could lead to a range of outcomes. Judgements are made for each position having regard to particular circumstances 
and advice obtained.

Deferred tax is provided for using the balance sheet liability method, and is recognised on temporary differences between the carrying amount 
of assets and liabilities in the financial statements and the corresponding tax bases.

Deferred tax liabilities are generally recognised on all taxable temporary differences, and deferred tax assets are recognised to the extent that it 
is probable that taxable profits will be available against which deductible temporary differences can be utilised. However, deferred tax assets and 
liabilities are not recognised if the temporary differences arise from the initial recognition of goodwill or from the initial recognition of other assets 
and liabilities in a transaction (other than a business combination) that affects neither the accounting nor the taxable profit or loss.

Deferred tax liabilities are recognised on taxable temporary differences arising on investments in subsidiaries and joint arrangements except where 
the Company is able to control the reversal of the temporary difference and it is probable that the temporary difference will not reverse in the 
foreseeable future.

Deferred tax is calculated at the tax rates that are expected to apply in the period when the liability is settled or the asset is realised, based on the 
tax rates and tax laws that have been enacted or substantively enacted by the reporting date.

The carrying amount of deferred tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient 
taxable profits will be available to allow all or part of the deferred tax asset to be recovered. Unrecognised deferred tax assets are reassessed at 
each reporting date and are recognised to the extent that it has become probable that future taxable profits will allow the deferred tax asset to be 
recovered.

Deferred tax assets and liabilities are offset when there is a legally enforceable right to offset current tax assets against current tax liabilities and  
when they relate to income taxes levied by the same tax authority and the Company and its subsidiaries intend to settle their current tax assets  
and liabilities on a net basis.

1.  Prior year adjustment is primarily due to agreement of prior period tax returns.
2.  Includes gains on chargeable disposals which are offset by previously unrecognised capital losses. 
3.  Other primarily comprises a recognition of deferred tax on previously unrecognised capital losses and claims for land remediation relief.

Factors that may affect future tax charges
On 17 March 2020, the UK government utilised the Provisional Collection of Taxes Act 1968 to substantively enact a reversal of the reduction in the 
main UK corporation tax rate to 17% with effect from 1 April 2020. The main UK corporation tax rate therefore remains at 19%. Deferred tax balances 
have been calculated at this rate. 

We will continue to monitor the developments driven by Brexit, the OECD’s Base Erosion and Profit Shifting (BEPS) project and European 
Commission initiatives including fiscal aid investigations. At this time, we do not expect this to have any material impact on our future tax charges. 
Governments across the world including the UK and the US have introduced various stimulus/reliefs for businesses to cope with the impact of the 
COVID-19 pandemic. We will monitor as the details become available for any that may materially impact our future tax charges.

1.   The deferred tax asset of £1,653 million as at 31 March 2020 (2019: £1,340 million) in respect of other net temporary differences primarily relates to net operating losses of £547 million 

(2019: £423 million) and US environmental provisions of £529 million (2019: £409 million).

2.   Exchange adjustments and other comprises foreign exchange arising on translation of the US dollar deferred tax balances. It also includes reclassification of £29 million from other 

temporary differences to share-based payments.

Deferred tax assets and liabilities are only offset where there is a legally enforceable right of offset and there is an intention to settle the balances 
net. The deferred tax balances (after offset) for statement of financial position purposes consist solely of deferred tax liabilities of £4,184 million 
(2019: £3,965 million). This balance is after offset of a deferred tax asset of £547 million (2019: £423 million) which has been recognised in respect of 
net operating losses (£535 million) and capital losses (£12 million).

Deferred tax assets in respect of some capital losses as well as trading losses and non-trade deficits have not been recognised as their future 
recovery is uncertain or not currently anticipated. The deferred tax asset not recognised relating to capital losses has increased due to 
remeasurement of opening deferred tax asset as a result of change in substantively enacted UK corporation tax rate from 17% to 19%. Hence the 
total deferred tax assets not recognised are as follows:

Capital losses

Non-trade deficits

Trading losses

The capital losses arose in the UK on disposal of certain businesses or assets. They are available to carry forward indefinitely but can only be offset 
against future capital gains. The UK non-trade deficits arose prior to 1 April 2017 and therefore can only be offset against future non-trade profits.

At 31 March 2020 and 31 March 2019, there were no recognised deferred tax liabilities for taxes that would be payable on the unremitted earnings of 
the Group’s subsidiaries or its associates as there are no significant corporation tax consequences of the Group’s UK, US or overseas subsidiaries or 
associates paying dividends to their parent companies. There are also no significant income tax consequences for the Group from the payment of 
dividends by the Group to its shareholders.

National Grid plc Annual Report and Accounts 2019/20Financial Statements8. Earnings per share (EPS)

EPS is the amount of post-tax profit attributable to each ordinary share. Basic EPS is calculated on profit for the year attributable to equity 
shareholders divided by the weighted average number of shares in issue during the year. Diluted EPS shows what the impact would be if all 
outstanding share options were exercised and treated as ordinary shares at year end. The weighted average number of shares is increased by 
additional shares issued as scrip dividends and reduced by shares repurchased by the Company during the year. The earnings per share 
calculations are based on profit after tax attributable to equity shareholders of the Company which excludes non-controlling interests.

Adjusted earnings and EPS, which exclude exceptional items and remeasurements, are provided to reflect the business performance sub-totals 
used by the Company. We have included reconciliations from this additional EPS measure to earnings for both basic and diluted EPS to provide 
additional detail for these items. For further details of exceptional items and remeasurements, see note 5.

Following the sale of the UK Gas Distribution business on 31 March 2017, National Grid plc returned £3,171 million of proceeds to shareholders 
through a special dividend, paid on 2 June 2017. In order to maintain the comparability of the Company’s share price before and after the special 
dividend, this was preceded by a share consolidation undertaken on 22 May 2017, replacing every 12 existing ordinary shares with 11 new ordinary 
shares. The weighted average number of ordinary shares outstanding for the year ended 31 March 2018 includes the effect of both the share 
consolidation and the special dividend from the date that the special dividend was paid. The associated share buyback programme which began  
on 2 June 2017 completed in March 2018. Purchased shares are held as treasury shares.

The Directors are proposing a final dividend for the year ended 31 March 2020 of 32.0p per share that will absorb approximately £1,123 million  
of shareholders’ equity (assuming all amounts are settled in cash). It will be paid on 19 August 2020 to shareholders who are on the register  
of members at 3 July 2020 (subject to shareholders’ approval at the AGM). A scrip dividend will be offered as an alternative. 

Following completion of the sale of the majority interest in UK Gas Distribution, the Company paid a special dividend on 2 June 2017 of 84.375p per 
existing ordinary share ($5.4224 per existing American Depositary Share). This returned £3,171 million to shareholders. No scrip dividend was offered 
as an alternative.

10. Discontinued operations and assets held for sale

The results and cash flows of significant assets or businesses sold during the year are shown separately from our continuing operations, and 
presented within discontinued operations in the income statement and cash flow statement. Assets and businesses are classified as held for sale 
when their carrying amounts are recovered through sale rather than through continuing use. They only meet the held for sale condition when the 
assets are ready for immediate sale in their present condition, management is committed to the sale and it is highly probable that the sale will 
complete within one year. Depreciation ceases on assets and businesses when they are classified as held for sale and the assets and businesses 
are impaired if the proceeds less sale costs fall short of the carrying value.

In June 2019, the Group sold its remaining 39% interest in Cadent (held through its holding in Quadgas HoldCo Limited (Quadgas)). This interest  
had been classified as held for sale from 30 June 2018 until the date of disposal, as detailed in the Annual Report and Accounts for the year ended 
31 March 2019. 

The aggregate carrying value of our investment in Quadgas at the disposal date was £1,956 million. This was comprised of the carrying value of the 
Group’s equity interest in Quadgas of £1,494 million, a shareholder loan to Quadgas of £352 million and a derivative financial asset with a fair value of 
£110 million. The total sales proceeds were £1,965 million. The gain on disposal was £9 million.

National Grid plc Annual Report and Accounts 2019/20Financial Statements10. Discontinued operations and assets held for sale continued
We considered the disposal of our 39% investment in Quadgas as the final stage of the plan to dispose of our interest in the UK Gas Distribution 
business first announced in 2015, and accordingly treated the results and cash flows arising from Quadgas as a discontinued operation on the basis 
that the sale formed the final part of a ‘single coordinated plan’ to dispose of UK Gas Distribution. As a consequence, we have classified the various 
elements of income, expense and cash flows within discontinued operations as set out below. Once the assets are treated as ‘held for sale’, equity 
accounting ceases for our investment in our associate. We therefore ceased to record our share of profits from 30 June 2018.

1.   Operating costs for the year ended 31 March 2020 relate to final transaction costs and other expenses in relation to Quadgas. Operating costs of £41 million for the year ended 31 March 

2018 related to amounts in respect of the disposal of the UK Gas Distribution business, primarily relating to the completion accounts settlement in November 2017. 

2.   For the year ended 31 March 2019, the amount presented is the net of £43 million impairment charge against the investment in Quadgas (see note 16) and £38 million share of Quadgas 

post-tax profits recognised prior to classification as held for sale.

3.   Of the total profit after tax from discontinued operations, the £23 million of operating expenses and the £9 million gain on disposal are treated as exceptional. For the year ended 31 March 

2019, the £43 million impairment charge against the investment in Quadgas, net operating costs of £1 million and the tax thereon are classified as exceptional items.

The summary cash flows for discontinued operations are as follows:

Cash flows used in operating activities of £97 million (2019: £71 million; 2018: £207 million) primarily related to cash outflows in respect of voluntary 
contributions totalling £66 million paid to the Warm Homes Fund, the utilisation of provisions and the payment of the final transaction fees incurred in the 
period. The utilisation of provisions in 2018 mainly related to payments of professional fees in respect of the disposal of the UK Gas Distribution business.

Cash inflows from investing activities of £6 million (2019: £156 million; 2018: £171 million) were comprised of dividends received and interest received 
on the shareholder loan. 

There were no cash flows for financing activities in 2020 or 2019. In 2018, net cash flows used in financing activities were £231 million for the 
settlement of RPI swaps relating to the final stages of the Group-wide liability management programme executed as part of sale process of the UK 
Gas Distribution business.

11. Goodwill

Goodwill represents the excess of what we paid to acquire businesses over the fair value of their net assets at the acquisition date. We assess 
whether goodwill is recoverable each year by performing an impairment review.

Goodwill is recognised as an asset and is not amortised, but is tested for impairment annually or more frequently if events or changes in 
circumstances indicate a potential impairment. Any impairment is recognised immediately in the income statement and is not subsequently reversed.

Goodwill and fair value adjustments arising on the acquisition of a foreign entity are treated as assets and liabilities of the foreign entity and translated 
at the closing exchange rate.

Goodwill is allocated to cash-generating units and this allocation is made to those cash-generating units that are expected to benefit from the 
business combination in which the goodwill arose.

Impairment is recognised where there is a difference between the carrying value of the cash-generating unit and the estimated recoverable amount 
of the cash-generating unit to which that goodwill has been allocated. Any impairment loss is first allocated to the carrying value of the goodwill and 
then to the other assets within the cash-generating unit. Recoverable amount is defined as the higher of fair value less costs to sell and estimated 
value-in-use at the date the impairment review is undertaken.

Value-in-use represents the present value of expected future cash flows, discounted using a pre-tax discount rate that reflects current market 
assessments of the time value of money and the risks specific to the asset for which the estimates of future cash flows have not been adjusted.

Impairments are recognised in the income statement and are disclosed separately.

Additions in the period relate to the goodwill recognised on the acquisition of Geronimo. Refer to note 38 for details.

There is no significant accumulated impairment charge as at 31 March 2020 or 31 March 2019.

The amounts disclosed above as at 31 March 2020 relate to the following cash-generating units: New York £3,544 million (2019: £3,382 million); 
Massachusetts £1,325 million (2019: £1,264 million); Rhode Island £493 million (2019: £470 million); Federal £790 million (2019: £753 million); and 
Geronimo £81 million (2019: £nil).

Goodwill is reviewed annually for impairment and the recoverability of goodwill has been assessed by comparing the carrying amount of our 
operations described above (our cash-generating units) with the expected recoverable amount on a value-in-use basis. In each assessment, the 
value-in-use has been calculated based on five-year plan projections that incorporate our best estimates of future cash flows, customer rates, costs 
(including changes in commodity prices), future prices and growth. Such projections reflect our current regulatory rate plans taking into account 
regulatory arrangements to allow for future rate plan filings and recovery of investment. Our plans have proved to be reliable guides in the past and 
the Directors believe the estimates are appropriate.

The future economic growth rate used to extrapolate projections beyond five years is 2.1% (2019: 2.2%). The growth rate has been determined 
having regard to data on projected growth in US real gross domestic product (GDP). Based on the position of our business in the underlying US 
economy, it is appropriate for the terminal growth rate to be based upon the overall growth in real GDP and, given the nature of our operations, to 
extend over a long period of time. Cash flow projections have been discounted to reflect the time value of money, using a post-tax discount rate of 
4.5% (2019: 5.3%). The equivalent pre-tax discount rate is 4.5% (2019: 5.3%) as tax is assumed to be a pass-through cost to our customers, 
recoverable under our rate plans. The discount rate represents the estimated weighted average cost of capital of these operations.

In reaching this conclusion, the Directors considered the manner in which Tax Reform has impacted the Group and its future cash flows. In our US 
business, we are subject to federal and state taxes; however, our regulatory arrangements require us to pass this cost back to our customers. The 
reduction in the corporation tax rate in 2018 from 35% to 21% is being reflected through lower bills to customers, reducing our revenues (and tax 
costs) in future periods. For the purposes of the goodwill impairment exercise, we have reflected the lower billing levels through lower revenue 
forecasts as well as lower tax charges.

Historically, as a result of tax losses arising from claiming accelerated depreciation allowances, we have not paid substantial amounts of tax in the 
US. Accordingly, for IFRS purposes, we have recognised significant deferred tax liabilities in respect of these accelerated allowances. In accounting 
terms, Tax Reform triggered the remeasurement of our deferred tax liabilities from 35% to 21% for the year ended 31 March 2018. However, the 
impact for our US business is that the amounts we have previously received from customers assuming a 35% federal tax rate instead of a 21% 
federal tax rate must now be returned to customers over a period of up to 50 years. Offsetting this change is the additional income we earn, since 
the rate base grows faster. (Our rate base is net of deferred tax liabilities, which, as a result of Tax Reform, is now smaller.) In overall terms, the 
outcome is economically neutral.

In assessing the carrying value of goodwill, we have sensitised our forecasts to factor in a reduction in revenues and lower tax costs into our cash 
flow forecasts, but we have not reflected the impact of additional rate base growth on future earnings. While it is possible that a key assumption in 
the calculation could change, the Directors believe that no reasonably foreseeable change would result in an impairment of goodwill, in view of the 
long-term nature of the key assumptions and the margin by which the estimated value-in-use exceeds the carrying amount. This remains the case 
even after taking into account the short-term effects of COVID-19, the most significant of which is an increase in bad debt charges in the short-term.

National Grid plc Annual Report and Accounts 2019/20Financial Statements12. Other intangible assets

Other intangible assets include software which is written down (amortised) over the period we expect to receive a benefit from the asset.

Identifiable intangible assets are recorded at cost less accumulated amortisation and any provision for impairment. Other intangible assets are tested 
for impairment only if there is an indication that the carrying value of the assets may have been impaired. Impairments of assets are calculated as the 
difference between the carrying value of the asset and the recoverable amount, if lower. Where such an asset does not generate cash flows that are 
independent from other assets, the recoverable amount of the cash-generating unit to which that asset belongs is estimated. Impairments are 
recognised in the consolidated income statement and are disclosed separately. Any assets which suffered impairment in a previous period are 
reviewed for possible reversal of the impairment at each reporting date.

Internally generated intangible assets, such as software, are recognised only if: i) an asset is created that can be identified; ii) it is probable that the 
asset created will generate future economic benefits; and iii) the development cost of the asset can be measured reliably. Where no internally 
generated intangible asset can be recognised, development expenditure is recorded as an expense in the period in which it is incurred.

Other intangible assets are amortised on a straight-line basis over their estimated useful economic lives. Amortisation periods for intangible 
assets are:

13. Property, plant and equipment

The following note shows the physical assets controlled by us. The cost of these assets primarily represents the amount initially paid for them. This 
includes both their purchase price and the construction and other costs associated with getting them ready for operation. A depreciation expense 
is charged to the income statement to reflect annual wear and tear and the reduced value of the asset over time. Depreciation is calculated by 
estimating the number of years we expect the asset to be used (useful economic life or UEL) and charging the cost of the asset to the income 
statement equally over this period.

We operate an energy networks business and therefore have a significant physical asset base. We continue to invest in our networks to maintain 
reliability, create new customer connections and ensure our networks are flexible and resilient. Our business plan envisages these additional 
investments will be funded through a mixture of cash generated from operations and the issue of new debt.

Property, plant and equipment is recorded at cost, less accumulated depreciation and any impairment losses. Cost includes the purchase price of 
the asset; any payroll and finance costs incurred which are directly attributable to the construction of property, plant and equipment; and the cost of 
any associated asset retirement obligations.

Property, plant and equipment includes assets in which the Group’s interest comprises legally protected statutory or contractual rights of use. Additions 
represent the purchase or construction of new assets, including capital expenditure for safety and environmental assets, and extensions to, enhancements 
to, or replacement of, existing assets. All costs associated with projects or activities which have not been fully commissioned at the period end are classified 
within assets in the course of construction. No depreciation is provided on freehold land or assets in the course of construction.

Other items of property, plant and equipment are depreciated, on a straight-line basis, at rates estimated to write off their book values over their 
estimated useful economic lives. In assessing estimated useful economic lives, consideration is given to any contractual arrangements and operational 
requirements relating to particular assets. The assessments of estimated useful economic lives and residual values of assets are performed annually.

Unless otherwise determined by operational requirements, the depreciation periods for the principal categories of property, plant and equipment are, 
in general, as shown in the table below split between the UK and US, along with the weighted average remaining UEL for each class of property, 
plant and equipment (which is calculated by applying the annual depreciation charge per class of asset by the net book value of that class of asset).

Gas asset lives
The role that gas networks play in the pathway to achieving the greenhouse gas emissions reductions targets set in the jurisdictions in which we 
operate is currently uncertain. However, we believe the gas assets which we own and operate today will continue to have a crucial role in maintaining 
security, reliability and affordability of energy beyond 2050, although the scale and purpose for which the networks will be used is dependent on 
technological developments and policy choices of governments and regulators. 

•  In the UK, the gas mains, services and regulating assets relating to the National Transmission System (NTS) were subject to a detailed review in 
January 2019. The most material components of these are our pipeline assets, which are due to be fully depreciated by 2070, with other assets 
being depreciated over various periods between now and then. That review was undertaken prior to the UK enacting legislation committing to 
net zero by 2050, but considered scenarios which included an extension of the emissions reduction targets (80% emissions reduction target at 
the time of the report). The review concluded that the most likely outcome was for the NTS network assets to remain in use beyond 2050, 
including in those scenarios where the greenhouse gas emissions of gas networks were largely eliminated.  

We do not believe developments since January 2019 would change the conclusions of this review.

•  With respect to our US gas distribution assets, asset lives are assessed as part of detailed depreciation studies completed as part of each 
separate rate proceeding. Depreciation studies consider the physical condition of assets and the expected operational life of an asset. We 
believe these assessments are our best estimate of the UEL of our gas network assets in the US. 

•   The weighted average remaining UEL for our US gas distribution fixed asset base is circa 50 years, however a sizeable proportion of our assets 
are assumed to have UELs which extend beyond 2080. We continue to believe the lives identified by rate proceedings are the best estimate of 
the assets’ UELs, although we continue to keep this assumption under review as we learn more about possible future pathways towards net 
zero. Whilst the targets, goals and ambitions have now been formalised in legislation in the states in which we operate, there is widespread 
recognition that work needs to be done to define the possible future decarbonisation pathways.

•   Asset depreciation lives feed directly into our regulatory recovery mechanisms, such that any shortening of asset recovery periods as agreed 
with regulators should be recoverable through future rates, subject to agreement, over future periods, as part of wider considerations around 
ensuring the continuing affordability of gas in our service territories.

Note that this sensitivity calculation excludes any assumptions regarding residual value for our asset base and the effect shortening asset 
depreciation lives would expect to have on our regulatory recovery mechanisms.

Items within property, plant and equipment are tested for impairment only if there is some indication that the carrying value of the assets may have 
been impaired. Impairments of assets are calculated as the difference between the carrying value of the asset and the recoverable amount, if lower. 
Where such an asset does not generate cash flows that are independent from other assets, the recoverable amount of the cash-generating unit to 
which that asset belongs is estimated. Impairments are recognised in the income statement and if immaterial are included within the depreciation 
charge for the year.

13. Property, plant and equipment continued
Right-of-use assets
The Group leases various properties, land, equipment and cars. With effect from 1 April 2019, new lease arrangements entered into are recognised 
as a right-of-use asset and a corresponding liability at the date at which the leased asset is available for use by the Group (see note 37). The 
right-of-use asset and associated lease liability arising from a lease are initially measured at the present value of the lease payments expected over 
the lease term, plus any other costs. The discount rate applied is the rate implicit in the lease or, if that is not available, then the incremental rate of 
borrowing for a similar term and similar security. The lease term takes account of exercising any extension options that are at our option if we are 
reasonably certain to exercise the option and any lease termination options unless we are reasonably certain not to exercise the option. Each lease 
payment is allocated between the liability and finance cost. The finance cost is charged to the income statement over the lease period using the 
effective interest rate method. The right-of-use asset is depreciated over the shorter of the asset’s useful life and the lease term on a straight-line 
basis. For short-term leases (lease term of 12 months or less) and leases of low-value assets (such as computers), the Group continues to recognise 
a lease expense on a straight-line basis.

Included within the net book value of property, plant and equipment at 31 March 2020 are right-of-use assets, split as follows:

National Grid plc Annual Report and Accounts 2019/20Financial Statements15. Financial and other investments

The Group holds a range of financial and other investments. These investments include short-term money funds, quoted investments in equities or 
bonds of other companies, long-term loans to our joint ventures, investments in our venture capital portfolio (National Grid Partners), bank deposits 
with a maturity of greater than three months, and cash balances that cannot be readily used in operations, principally collateral pledged against 
derivative holdings.

The Group has reported four categories of financial investments, and the classification for each investment is dependent on its contractual cash 
flows and the business model it is held under and recognised on trade date.

Debt instruments that have contractual cash flows that are solely payments of principal and interest, and which are held within a business model 
whose objective is to collect contractual cash flows, are held at amortised cost. This category includes our long-term loans to joint ventures as well 
as receivables in relation to deposits and collateral. 

Debt investments that have contractual cash flows that are solely payments of principal and interest, and which are held within a business model 
whose objective is both to collect the contractual cash flows and to sell the debt instruments, are measured at fair value through other 
comprehensive income. On disposal, any realised gains or losses are recycled to the income statement in investment income (see note 6). Other 
investments include insurance contracts, measured at fair value, and held to back the present value of unfunded obligations in note 25. 

The Group has elected to measure equity instruments at fair value through other comprehensive income that are shares held as part of a portfolio 
of financial instruments which back some long-term employee liabilities. They are not held for trading and so recognising gains and losses on these 
investments in profit and loss would not be representative of performance in the year. On disposal, any realised gains and losses are transferred to 
retained profits (see note 28).

Other financial investments are subsequently measured at fair value through profit and loss. This primarily comprises our money market funds, 
insurance company fund investments and corporate venture capital investments held by National Grid Partners.

Financial and other investments are initially recognised on trade date. Subsequent to initial recognition, the fair values of financial assets that are 
quoted in active markets are based on bid prices. When independent prices are not available, fair values are determined using valuation techniques 
used by the relevant markets. The techniques use observable market data to the extent available.

15. Financial and other investments continued
Fair value through profit and loss and fair value through other comprehensive income investments are recorded at fair value. The carrying value of 
current financial assets at amortised cost approximates their fair values, primarily due to short-dated maturities. The carrying value of the non-current 
loans to joint ventures approximates their fair values as at 31 March 2019. The exposure to credit risk at the reporting date is the fair value of the 
financial investments. For further information on our credit risk, refer to note 32(a). 

For the purposes of impairment assessment, the investments in bonds are considered to be low risk as they are managed with an investment remit 
to hold investment grade securities; life insurance policies are held with regulated insurance companies; and deposits, collateral receivable and other 
financial assets at amortised cost are investment grade. All financial assets held at fair value through other comprehensive income or amortised cost 
are therefore considered to have low credit risk and have a loss allowance equal to 12-month expected credit losses.

In determining the expected credit losses for these assets, some or all of the following information has been considered: credit ratings, the financial 
position of counterparties, the future prospects of the relevant industries and general economic forecasts.

No fair value through other comprehensive income or amortised cost financial assets have had modified cash flows during the period. There has 
been no change in the estimation techniques or significant assumptions made during the year in assessing the loss allowance for these financial 
assets. There were no significant movements in the gross carrying value of financial assets during the year that contribute to changes in the loss 
allowance. No collateral is held in respect of any of the financial investments in the above table. No balances are more than 30 days past due, and no 
balances were written off during the year.

16. Investments in joint ventures and associates 

Investments in joint ventures and associates represent businesses we do not control but over which we exercise joint control or significant 
influence. They are accounted for using the equity method. A joint venture is an arrangement established to engage in economic activity, which the 
Group jointly controls with other parties and has rights to the net assets of the arrangement. An associate is an entity which is neither a subsidiary 
nor a joint venture, but over which the Group has significant influence.

– analysis of items in the primary statements continued

17. Derivative financial instruments

Derivatives are financial instruments that derive their value from the price of an underlying item such as interest rates, foreign exchange rates, 
credit spreads, commodities, equities or other indices. In accordance with policies approved by the Board, derivatives are transacted generally to 
manage exposures to fluctuations in interest rates, foreign exchange rates and commodity prices. Our derivatives balances comprise two broad 
categories:

•  financing derivatives managing our exposure to interest rates and foreign exchange rates. Specifically, we use these derivatives to manage 

our financing portfolio, holdings in foreign operations and contractual operational cash flows; and

•  commodity contract derivatives managing our US customers’ exposure to price and supply risks. Some forward contracts for the purchase 

of commodities meet the definition of derivatives and are included here. We also enter into derivative financial instruments linked to 
commodity prices, including index futures, options and swaps. These are used to manage market price volatility.

Derivatives are initially recognised at fair value and subsequently remeasured to fair value at each reporting date. Changes in fair values are recorded 
in the period they arise, in either the consolidated income statement or other comprehensive income as required by IFRS 9. Where the gains or 
losses recorded in the income statement arise from changes in the fair value of derivatives to the extent that hedge accounting is not applied or is not 
fully effective, these are recorded as remeasurements, detailed in notes 5 and 6. Where the fair value of a derivative is positive it is carried as a 
derivative asset, and where negative as a derivative liability.

We calculate the fair value of derivative financial instruments by taking the present value of future cash flows, primarily incorporating market 
observable inputs. The various inputs include foreign exchange spot and forward rates, yield curves of the respective currencies, currency basis 
spreads between the respective currencies, interest rate and inflation curves, the forward rate curves of underlying commodities, and for those 
positions that are not fully cash collateralised the credit quality of the counterparties. 

Certain clauses embedded in non-derivative financial instruments or other contracts are presented as derivatives because they impact the risk profile 
of their host contracts and they are deemed to have risks or rewards not closely related to those host contracts. 

Further information on how derivatives are valued and used for risk management purposes is presented in note 32.

Information on commodity contracts and other commitments not meeting the definition of derivatives is presented in note 30.

The fair values of derivatives by category are as follows:

18. Inventories and current intangible assets

Inventories represent assets that we intend to use in order to generate revenue in the short term, either by selling the asset itself (for example, fuel 
stocks) or by using it to fulfil a service to a customer or to maintain our network (consumables).

Inventories are stated at the lower of weighted average cost and net realisable value. Where applicable, cost comprises direct materials and direct 
labour costs as well as those overheads that have been incurred in bringing the inventories to their present location and condition.

Emission allowances, principally relating to the emissions of carbon dioxide in the UK and sulphur and nitrous oxides in the US, are recorded as 
intangible assets within current assets, and they are initially recorded at cost and subsequently at the lower of cost and net realisable value. A liability 
is recorded in respect of the obligation to deliver emission allowances, and emission charges are recognised in the income statement in the period 
in which emissions are made.

Current intangible assets – emission allowances

There is a provision for obsolescence of £21 million against inventories as at 31 March 2020 (2019: £20 million).

Trade receivables are non-interest-bearing and generally have a 30 to 90 days term. Due to their short maturities, the fair value of trade and other 
receivables approximates their carrying value. The maximum exposure of trade receivables to credit risk is the gross carrying amount of 
£2,063 million (2019: £2,293 million).

Provision for impairment of receivables
A provision for credit losses is recognised at an amount equal to the expected credit losses that will arise over the lifetime of the trade receivables 
and accrued income.

There are no retail customers in the UK businesses. A provision matrix is not used in the UK as an assessment of expected losses on individual 
debtors is performed, and the provision is not material. 

In the US, £1,806 million (2019: £1,885 million) of the trade receivables and unbilled revenue balance is attributable to retail customers. For non-retail 
US customer receivables, a provision matrix is not used and expected losses are determined on individual debtors. 

The provision for retail customer receivables in the US is calculated based on a series of provision matrices which are prepared by regulated entity 
and by customer type. The expected loss rates in each provision matrix are based on historical loss rates adjusted for current and forecasted 
economic conditions at the balance sheet date. The inclusion of forward-looking information in the provision matrix setting process under IFRS 9 
resulted in loss rates that reflect expected future economic conditions and the recognition of an expected loss on all debtors even where no loss 
event has occurred. 

In March 2020, the Group’s US distribution businesses ceased certain customer cash collection activities in response to regulatory instructions  
and to changes in State, Federal and City level regulations and guidance, and actions to minimise risk to the Group’s employees. The Group has  
also ceased customer termination activities as requested by relevant local authorities. In addition, we have considered the macroeconomic data 
including unemployment levels and our previous experience regarding debtor recoverability during and in the aftermath of the 2008/09 financial  
crisis (which impacted all of our service territories) and that following Superstorm Sandy in 2012 which impacted our downstate New York gas 
business specifically.

Based on our review of these factors, we concluded that a reasonable range for the additional provision recognised in light of the cessation  
of customer terminations and collections following the moratoriums introduced would lie between £81 million and £161 million ($100 million  
and $200 million). We concluded an additional charge of £117 million represented our best estimate based on the information available, primarily  
as this represented an impact twice as severe as Superstorm Sandy, adjusted to incorporate all service territories impacted.

The year-on-year movements in average expected loss rates are driven primarily as a result of the moratoriums on cash collection and termination 
activities outlined above. 

US retail customer receivables are not collateralised. Trade receivables are written off when regulatory requirements are met. Write-off policies vary 
between jurisdictions as they are aligned with the local regulatory requirements, which differ between regulators. There were no significant amounts 
written off during the period that were still subject to enforcement action. Our internal definition of default is aligned with that of the individual 
regulators in each jurisdiction.

For further information on our wholesale and retail credit risk, refer to note 32(a). 

20. Cash and cash equivalents

Cash and cash equivalents include cash balances, together with short-term investments with an original maturity of less than three months that are 
readily convertible to cash.

Net cash and cash equivalents reflected in the cash flow statement are net of bank overdrafts, which are reported in borrowings. The carrying 
amounts of cash and cash equivalents and bank overdrafts approximate their fair values.

Cash at bank earns interest at floating rates based on daily bank deposit rates. Short-term deposits are made for periods varying between one 
day and three months, depending on the immediate cash requirements, and earn interest at the respective short-term deposit rates.

Net cash and cash equivalents held in currencies other than sterling have been converted into sterling at year-end exchange rates. For further 
information on currency exposures, refer to note 32(c).

National Grid plc Annual Report and Accounts 2019/20Financial Statements21. Borrowings

We borrow money primarily in the form of bonds and bank loans. These are for a fixed term and may have fixed or floating interest rates or are 
linked to RPI. We use derivatives to manage risks associated with interest rates and foreign exchange. 

Our price controls and rate plans lead us to fund our networks within a certain ratio of debt to equity and, as a result, we have issued a significant 
amount of debt. As we continue to invest in our networks, the value of debt is expected to increase over time. To maintain a strong balance sheet 
and to allow us to access capital markets at commercially acceptable interest rates, we balance the amount of debt we issue with the value of our 
assets, and we take account of certain other metrics used by credit rating agencies.

All borrowings are accounted for at amortised cost, with the exception of one liability measured at fair value through profit and loss, in order to 
eliminate a measurement mismatch.

Borrowings, which include interest-bearing, zero-coupon and inflation-linked debt, overdrafts and collateral payable, are initially recorded at fair value. 
This normally reflects the proceeds received (net of direct issue costs for liabilities measured at amortised cost). Subsequently, borrowings are stated 
either: i) at amortised cost; or ii) at fair value though profit and loss. Where a borrowing is held at amortised cost, any difference between 
the proceeds after direct issue costs and the redemption value is recognised over the term of the borrowing in the income statement using the 
effective interest method. For the liability held at fair value through profit and loss, interest is calculated using the effective interest method.

Where a borrowing or liability is held at fair value, changes in the fair value of the borrowing due to changes in the issuer’s credit risk are recorded in 
the own credit reserve (see note 28). All other changes in the fair value of the liability are recognised in the income statement within remeasurements 
(see notes 5 and 6).

The fair value of borrowings at 31 March 2020 was £34,174 million (2019: £32,252 million). Where market values were available, fair value of 
borrowings (Level 1) was £14,059 million (2019: £14,356 million). Where market values were not available, fair value of borrowings (Level 2) was 
£20,115 million (2019: £17,896 million), calculated by discounting cash flows at prevailing interest rates. The notional amount outstanding of the debt 
portfolio at 31 March 2020 was £30,422 million (2019: £28,417 million).

In April 2020, National Grid Electricity Transmission plc issued a £0.4 billion fixed interest rate bond from the NGET EMTN programme with a 20-year 
tenor and The Narragansett Electric Company issued a $0.6 billion (£0.5 billion) fixed interest rate bond with a 10-year tenor. Both issuances are part 
of the continued Group funding arrangements.

During the year, the assets of the Colonial Gas Company were merged with the Boston Gas Company, and have been ringfenced post-merger, and 
certain gas distribution assets of The Narragansett Electric Company are subject to liens and other charges and are provided as collateral over 
borrowings totalling £84 million at 31 March 2020 (2019: £81 million). 

Collateral is placed with or received from any derivative counterparty where we have entered into a credit support annex to the ISDA Master 
Agreement once the current mark-to-market valuation of the trades between the parties exceeds an agreed threshold. Included in current bank loans 
is £785 million (2019: £558 million) in respect of cash received under collateral agreements. For further details of our borrowing facilities, refer to note 
33. For further details of our bonds in issue, please refer to the debt investor section of our website. Unless included herein, the information on our 
website is unaudited.

Financial liability at fair value through profit and loss
The financial liability designated at fair value through profit and loss is analysed as follows:
i.  the fair value of the liability was £741 million (2019: £667 million), which includes cumulative change in fair value attributable to changes in credit 

risk recognised in other comprehensive income, post tax of £10 million (2019: £13 million);
ii.  the amount repayable at maturity in November 2021 is £759 million (2019: £724 million); and
iii. the difference between carrying amount and contractual amount at maturity is £18 million (2019: £57 million).

This liability has been reclassified in order to eliminate a measurement mismatch with derivatives which provide an economic hedge. The associated 
derivatives are collateralised and do not contain significant exposure to our own credit risk. The presentation of credit risk in other comprehensive 
income does not, therefore, create or enlarge an accounting mismatch in profit or loss. 

The change in the fair value attributable to a change in credit risk is calculated as the difference between the total change in the fair value of the 
liability and the change in the value of the liability due to changes in market risk factors alone. The change in the fair value due to market risk factors 
was calculated using benchmark yield curves as at the end of the reporting period holding the credit risk margin constant. The fair value of the liability 
was calculated using observed market prices.

National Grid plc Annual Report and Accounts 2019/20Financial Statements21. Borrowings continued
Lease liabilities
The Group adopted IFRS 16 on 1 April 2019, which resulted in the recognition of £474 million of additional lease liabilities. As we applied the modified 
retrospective approach to transition, comparatives were not restated. Refer to note 37 for details.

Lease liabilities are initially measured at the present value of the lease payments expected over the lease term. The discount rate applied is the rate 
implicit in the lease or if that is not available, then the incremental rate of borrowing for a similar term and similar security. The lease term takes 
account of exercising any extension options that are at our option if we are reasonably certain to exercise the option and any lease termination 
options unless we are reasonably certain not to exercise the option. Each lease payment is allocated between the liability and finance cost. The 
finance cost is charged to the income statement over the lease period using the effective interest rate method.

Gross lease liabilities are repayable as follows:

Less than 1 year

1 to 5 years

More than 5 years

Less: finance charges allocated to future periods

The present value of lease liabilities are as follows:

Less than 1 year

National Grid plc Annual Report and Accounts 2019/20Financial Statements25. Pensions and other post-retirement benefits

All of our employees are eligible to participate in a pension plan. We have defined benefit (DB) and defined contribution (DC) pension plans in the 
UK and the US. In the US we also provide healthcare and life insurance benefits to eligible employees, post-retirement. The fair value of associated 
plan assets and present value of DB obligations are updated annually in accordance with IAS 19 (revised). We separately present our UK and US 
pension plans to show geographical split. Below we provide a more detailed analysis of the amounts recorded in the primary financial statements 
and the actuarial assumptions used to value the DB obligations.

National Grid’s UK pension arrangements are held in separate Trustee administered funds. The arrangements are managed by Trustee companies 
with boards consisting of company- and member-appointed directors. In the US, the assets of the plans are held in trusts and administered by the 
Retirement Plans Committee comprised of appointed employees of the Company.

Defined contribution plans
These plans are designed to provide members with a pension pot for their retirement. The risks associated with these plans are assumed by the 
member.

Payments to these DC plans are charged as an expense as they fall due. There is no legal or constructive obligation on National Grid to pay 
additional contributions into a DC plan if the fund has insufficient assets to pay all employees’ benefits relating to employee service in the current and 
prior periods.

The National Grid YouPlan
YouPlan is the qualifying UK pension plan that is used for automatic enrolment of new hires.

National Grid pays contributions into YouPlan to provide DC benefits on behalf of employees. National Grid provides a double match of member 
contributions, up to a maximum Company contribution of 12% of salary as well as the cost of administration and insured benefits. 

Defined benefit plans
On retirement, members of DB plans receive benefits whose value is dependent on factors such as salary and length of pensionable service. 
National Grid’s obligation in respect of DB pension plans is calculated separately for each DB plan by projecting the estimated amount of future 
benefit payments that employees have earned for their pensionable service in the current and prior periods. These future benefit payments 
are discounted to determine the present value of the liabilities. Current service cost and any unrecognised past service cost are recognised 
immediately. The discount rate used is the yield curve at the valuation date on high-quality corporate bonds.

Advice is taken from independent actuaries relating to the appropriateness of the key assumptions applied, including life expectancy, expected salary 
and pension increases, and inflation. Comparatively small changes in the assumptions used may have a significant effect on the amounts recognised 
in the consolidated income statement, the consolidated statement of other comprehensive income and the net liability recognised in the consolidated 
statement of financial position.

Remeasurements of pension assets and post-retirement benefit obligations are recognised in full in the period in which they occur in the 
consolidated statement of other comprehensive income.

The principal UK DB pensions plans are the National Grid UK Pension Scheme (NGUKPS) and the National Grid Electricity Group of the Electricity 
Supply Pension Scheme (NGEG of ESPS). In the US, we have four principal plans and various healthcare and life insurance plans.

The COVID-19 pandemic
The COVID-19 pandemic has had a global impact on economies, equity and bond markets. Market volatility during March has had an impact on the 
value of assets held by our DB and DC pension plans. Our UK DB plans have low-risk investment strategies with limited exposure to equities and 
other return seeking assets, whilst the US plans have a greater exposure to these asset classes.

UK Pensions plans
The arrangements are subject to independent actuarial funding valuations at least every three years, and following consultation and agreement 
with us, the qualified actuary certifies the employers’ contributions, which, together with the specified contributions payable by the employees 
and proceeds from the plans’ assets, are expected to be sufficient to fund the benefits payable.

The results of the most recent actuarial valuations are shown below. See page 167 for the assumptions used for IAS 19 (revised) purposes. The 
actuarial valuations for NGUKPS as at 31 March 2019 have recently been completed, while we expect the valuation for NGEG of ESPS to be finalised 
by 30 June 2020.

25. Pensions and other post-retirement benefits continued

National Grid UK Pension Scheme
NGUKPS consists of three sections, each legally and actuarially separate. Sections A and B are supported by companies within the Group, 
while Section C is supported by Cadent Gas Limited, now an unrelated third party. The plan closed to new hires on 1 April 2002.

Section A
Following the latest actuarial valuation at 31 March 2019, Section A remains in surplus, and so no deficit funding contributions are required. National 
Grid and the Trustees have agreed a schedule of contributions whereby the employers will continue to contribute 51.8% of pensionable salary, less 
member contributions, in respect of future benefit accrual. 

As part of the sectionalisation of NGUKPS on 1 January 2017, a guarantee of £1 billion has been provided to Section A. This payment is contingent 
on insolvency or on failure to pay pension obligations to Section A and can be claimed against National Grid plc, National Grid Holdings One plc or 
Lattice Group Limited (up to £1 billion in total).

Section B
The latest full actuarial valuation at 31 March 2019 determined that Section B was in deficit. In addition to a £34 million payment already made in 
September 2019, National Grid and the Trustees agreed that an additional payment of approximately £32 million will be made by September 2020  
to eliminate the funding deficit. In addition, the employers contribute 51.4% of pensionable salary, less member contributions, in respect of future 
benefit accrual.

Pensions buy-ins
During the year, the Trustees of the NGUKPS entered into two buy-in arrangements in order to manage various risks. The policies provide bulk 
annuities in respect of some pensioner and dependant members of Sections A and B of NGUKPS and were funded by existing assets. In Section A, 
£2.8 billion of gilts were exchanged for a buy-in policy with Rothesay Life. In Section B, £1.6 billion of gilts were exchanged for a buy-in policy with 
Legal & General. Both policies are held by the Trustee. For both transactions, the pricing of the policies was highly competitive; however, under IAS 
19 the methodology for calculating the value of the buy-ins (as an asset held by the pension plan) differs from the price paid. This resulted in the 
recognition of an actuarial loss of £0.7 billion on purchase, recorded within the consolidated statement of other comprehensive income. 

National Grid Electricity Group of the Electricity Supply Pension Scheme
The last full actuarial valuation for the NGEG of the ESPS determined that the plan was in deficit. National Grid and the Trustees agreed on a 
schedule of contributions, whereby deficit funding of £48 million is payable each year from 2016 to 2027, which should lead to the elimination of the 
funding shortfall by March 2027. All deficit funding amounts due will be adjusted for changes in the RPI. In addition, National Grid contributes 40.7% 
of pensionable salary, less member contributions, in respect of the ongoing service cost. The plan closed to new hires from 1 April 2006.

The plan holds a longevity insurance contract which covers improvements in longevity, providing long-term protection to the scheme, should some 
pensioner and dependant members live longer than currently expected. 

Administration costs
Up to 31 March 2020, National Grid was responsible for the costs of plan administration and the Pension Protection Fund (PPF) levies for both 
Sections A and B of NGUKPS, and NGEG of ESPS. However, from 1 April 2020 onwards this will only apply to Section B of NGUKPS and NGEG of 
ESPS, whilst Section A of NGUKPS will fund these costs from the Section’s assets.

Security arrangements
National Grid has also established security arrangements with charges in favour of the Trustees.

1.  Following the completion of the March 2019 valuations for Sections A and B of NGUKPS, these amounts have changed to £186 million for Section A and to £nil for Section B.
2.  These amounts are payable if certain trigger events occur which have been individually agreed between the plans and their relevant supporting employers.

The majority of the security is provided in the form of surety bonds with the remainder in letters of credit. The assets held in security will be paid to 
the respective section or plan in the event that the relevant supporting employer is subject to an insolvency event or fails to make the required 
contributions; and applicable to NGEG of ESPS only, if NGET loses its licence to operate under relevant legislation. Counter indemnities have also 
been taken out to ensure the obligations will be fulfilled.

National Grid plc Annual Report and Accounts 2019/20Financial Statements25. Pensions and other post-retirement benefits continued
US pension plans
National Grid has multiple DC pension plans which allow employee as well as Company contributions. Non-union employees hired after 1 January 
2011, as well as new hire represented union employees, receive a core contribution into the DC plan, irrespective of the employee’s contribution into 
the plan.

National Grid sponsors four non-contributory qualified DB pension plans, which provide vested union employees, and vested non-union employees 
hired before 1 January 2011 with retirement benefits within prescribed limits as defined by the US Internal Revenue Service. National Grid also 
provides non-qualified DB pension arrangements for a section of current and former employees, which are closed to new entrants. Benefits under 
the DB plans generally reflect age, years of service and compensation and are paid in the form of an annuity or lump sum. An independent actuary 
performs valuations annually. The Company funds the DB plans by contributing no less than the minimum amount required, but no more than the 
maximum tax-deductible amount allowed under US Internal Revenue Service regulations. The range of contributions determined under these 
regulations can vary significantly depending upon the funded status of the plans. At present, there is some flexibility in the amount that is contributed 
on an annual basis. In general, the Company’s policy for funding the US pension plans is to contribute the amounts collected in rates and capitalised 
in the rate base during the year, to the extent that the funding is no less than the minimum amount required. For the current financial year, these 
contributions amounted to approximately £153 million (2019: £231 million).

US retiree healthcare and life insurance plans
National Grid provides healthcare and life insurance benefits to eligible employees, post-retirement. Eligibility is based on certain age and length of 
service requirements, and in most cases, retirees contribute to the cost of their healthcare coverage. In the US, there is no governmental requirement 
to pre-fund post-retirement healthcare and life insurance plans. However, in general, the Company’s policy for funding the US retiree healthcare and 
life insurance plans is to contribute amounts collected in rates and capitalised in the rate base during the year. For the current financial year, these 
contributions amounted to £18 million (2019: £14 million).

For the last few years it has been the Company’s policy to primarily direct contributions to the DB pension plans due to concerns over tax deductible 
limitations relating to the retiree and healthcare and life insurance plans.

Actuarial assumptions
The Company has applied the following financial assumptions in assessing DB liabilities:

Discount rate – past service

Discount rate – future service

Salary increases

Rate of increase in RPI – past service

Rate of increase in RPI – future service

At 31 March 2020, single equivalent financial assumptions are shown above for presentational purposes, although full yield curves have been used in 
our calculations. In 2018 and 2019, single equivalent financial assumptions were set which reflected the average duration for the aggregate past and 
future service obligations. 

The discount rate is determined by reference to high-quality UK corporate bonds at the reporting date. The rate of increase in salaries has been set 
using a promotional scale where appropriate. The rates of increases stated are not indicative of historical increases awarded or a guarantee of future 
increase, but merely an appropriate assumption used in assessing DB liabilities. Retail Price Index (RPI) is the key assumption that determines 
assumed increases in pensions in payment and deferment in the UK only.

Discount rates for US pension liabilities have been determined by reference to appropriate yields on high-quality US corporate bonds at the reporting 
date based on the duration of plan liabilities. The healthcare cost trend rate is expected to reach the ultimate trend rate by 2030 (2019: 2028).

Maturity profile of DB obligations
The weighted average duration of the DB obligation for each category of plan is 14 years for UK pension plans; 14 years for US pension plans and  
16 years for US other post-retirement benefit plans.

As at the reporting date, the present value of the funded obligations split according to member status was approximately:
•  UK pensions: 8% active members (2019: 10%; 2018: 10%); 14% deferred members (2019: 16%; 2018: 18%); 78% pensioner members (2019: 

74%; 2018: 72%);

•  US pensions: 36% active members (2019: 37%; 2018: 38%); 9% deferred members (2019: 9%; 2018: 8%); 55% pensioner members (2019: 

54%; 2018: 54%); and

•  US other post-retirement benefits: 35% active members (2019: 39%; 2018: 38%); 0% deferred members (2019: 0%; 2018: 0%); 65% pensioner 

members (2019: 61%; 2018: 62%).

The recognition of the pension assets in both the UK in relation to the NGUKPS, the NGEG of ESPS and the US in relation to Niagara Mohawk Plan 
reflects legal and actuarial advice that we have taken regarding recognition of surpluses under IFRIC 14. We have concluded that the Group has 
an unconditional right to a refund from the individual plans, including from each Section of the NGUKPS and the NGEG of ESPS, in the event of a 
winding up. In the UK, the Trustees must seek the agreement of the Company to any benefit augmentation beyond the provisions set out in the 
Scheme Rules. In the US, surplus assets may be used to pay benefits under other Plans, thereby allowing the Company to settle other liabilities 
under other Plans.

1.  For the year ended 31 March 2020, UK pensions includes an actuarial loss from the purchase of buy-in policies of £0.7 billion.

The markets for unquoted investments are illiquid and the valuations that have been provided by fund managers as at 31 March 2020 may be based 
on valuation models that have unobservable inputs. Given the current market volatility that has arisen as a result of COVID-19, this means that the 
prices provided are subject to additional estimation uncertainty. Sensitivity analyses for changes in private equity, property and diversified alternative 
valuations have been provided in note 35.

Defined benefit investment strategies and risks
DB pension plans can pose a significant risk to future cash flows, as National Grid underwrites the financial and demographic risks associated with 
these plans. Although the governing bodies have sole responsibility for setting investment strategies and managing risks, National Grid closely works 
with and supports the governing bodies of each plan, to assist them in mitigating the risks associated with their plans and to ensure that the plans 
are funded to meet their obligations.

In the UK, each plan has a Trustee that is the governing body. The Trustees’ responsibilities are set out in the Trust Deed and Rules. In the US, the 
fiduciary committee for all the retirement plans is the Retirement Plan Committee (RPC). The RPC is structured in accordance with US laws 
governing retirement plans under the Employee Retirement Income Security Act (ERISA).

The Trustees and RPC, after taking advice from professional investment advisors and in consultation with National Grid, set the key principles, 
including expected returns, risk and liquidity requirements. In setting these they take into account expected contributions, maturity of the pension 
liabilities, and in the UK, the strength of the covenant. The Trustees and RPC formulate an investment strategy to manage risk through diversification, 
including the use of liability-matching assets, which move in line with the long-term liabilities of the plan, and return-seeking assets, some of which 
are designed to mitigate downside risk. Where appropriate, the strategies may include interest rate and inflation hedging instruments, and currency 
hedging to hedge overseas holdings.

Investments are usually grouped into:
•  Return-seeking assets: equities, property and diversified funds where the objective is to achieve growth within the constraints of the plans’ risk 

profiles. These assets should produce returns greater than the liability increase, so improving the funding position, and are assessed by 
reference to benchmarks and performance targets agreed with the investment managers; and

•  Liability-matching assets: liability-driven investment (LDI) funds, buy-ins, government securities, corporate bonds and swaps, where the 

objective is to secure fixed or inflation-adjusted cash flows in future. These investments are generally expected to match the change in liability 
valuation, so protecting the funding position. Bonds and securities are also measured against certain market benchmarks.

Investments are predominantly made in assets considered to be of investment grade. Where investments are made in non-investment grade assets, 
the higher volatility involved is carefully judged and balanced against the expected higher returns. Similarly, investments are made predominantly in 
regulated markets. Where investments are made either in non-investment grade assets or outside of regulated markets, investment levels are kept to 
prudent levels and subject to agreed control ranges, to control the risk. Should these investments fall outside the pre-agreed ranges, corrective 
actions and timescales are agreed with the investment manager to remedy the position. 

The governing bodies ensure that the performance of investment managers is regularly reviewed against measurable objectives, consistent with 
each pension plan’s long-term objectives and accepted risk levels. Where required, the portfolios are amended, or investment managers changed.

The Trustees and RPC can generally delegate responsibility for the selection of specific bonds, securities and other investments to appointed 
investment managers. Investment managers are selected based on the required skills, expertise of those markets, process and financial security to 
manage the investments. The investment managers use their skill and expertise to manage the investments competently. In some cases, they may 
further delegate this responsibility, through appointing sub-managers. 

The pension plans hold sufficient cash to meet benefit requirements, with other investments being held in liquid or realisable assets to meet 
unexpected cash flow requirements. The plans do not borrow money, or act as guarantor, to provide liquidity to other parties (unless it is temporary).

In the UK, both NGUKPS and NGEG of ESPS have Responsible Investment (RI) Policies, which take into account Environmental, Social and 
Governance (ESG) areas. The NGUKPS RI also incorporates the six UN-backed Principles for Responsible Investment (UNPRI). The Trustees believe 
that ESG factors can be material to financial outcomes and therefore these should and will be considered alongside other factors. The Trustees 
recognise that their primary responsibility remains a fiduciary one, i.e. their first duty is to ensure the best possible return on investments with the 
appropriate level of risk. However, the Trustees also recognise the increasing materiality of ESG factors and that they have a fiduciary and regulatory 
duty to consider RI, including ESG factors and the potential impact on the quality and sustainability of long-term investment returns and therefore on 
the Trustees’ primary fiduciary duty.

Whilst in the US there is no regulatory requirement to have ESG-specific principles embedded in investment policies, investment managers often 
utilise ESG principles to inform their decision-making process.

The most significant risks associated with the DB plans are:
•  Asset volatility – the plans invest in a variety of asset classes, but principally in government securities, bulk annuities, corporate bonds,  

equities and property. Consequently, actual returns will differ from the underlying discount rate adopted, impacting on the funding position  
of the plan through the net balance sheet asset or liability. Each plan seeks to balance the level of investment return required with the risk that  
it can afford to take, to design the most appropriate investment portfolio. Volatility will be controlled through using liability-matching asset 
strategies including bulk annuities, as well as interest rate hedging and management of foreign exchange exposure, and diversification of  
the return-seeking assets; 

•  Changes in bond yields – liabilities are calculated using discount rates set with reference to the yields in high-quality corporate bonds prevailing 

in the UK and US debt markets and will fluctuate as yields change;

•  Member longevity – longevity is a key driver of liabilities and changes in life expectancy have a direct impact on liabilities. The NGEG of ESPS 
holds a longevity insurance contract (“longevity swap”) and NGUKPS holds buy-in policies for both Sections A and B, which covers exposure 
to improvement in longevity, providing long-term protection in the event that members live longer than expected;

•  Counterparty risk – is managed by having a diverse range of counterparties and through having a strong collateralisation process (including for 

the longevity swap held by NGEG of ESPS). Measurement and management of counterparty risk is delegated to the relevant investment 
managers. For our bulk annuity policies, various termination provisions were introduced in the contracts, managing our exposure to 
counterparty risk. The insurers’ operational performance and financial strength are monitored on a regular basis;

•  Deficit risk – the risk that the increase in the liability will outpace the growth in assets is managed through assessing the progress of the actual 

growth of the liabilities relative to the selected investment policy and adjusting the policy as required;

•  Manager risk – expected deviation of the return, relative to the benchmark, is carefully monitored, as is the process, team and expertise of the 
manager. Where appropriate, the Trustee or RPC will move assets under management to a more robust manager, whom they consider will 
have a better expectation of performing well in the future;

•  Currency risk – fluctuations in the value of foreign denominated assets due to exposure to currency exchange rates is managed through a 

combination of segregated currency hedging overlay and currency hedging carried out by some of the investment managers;

172

National Grid plc Annual Report and Accounts 2019/20Financial Statements25. Pensions and other post-retirement benefits continued
Defined benefit investment strategies and risks continued
•  Interest rate and inflation risk – changes in inflation will affect the current and future pensions but are partially mitigated through investing in 

inflation-matching assets and hedging instruments as well as bulk annuity buy-in policies;

•  Investment funds – the credit risk arising from investing in investment funds is mitigated by the underlying assets of the investment funds being 

ring-fenced from the fund managers, the regulatory environments in which the fund managers operate and diversification of investments 
among investment fund arrangements;

•  Political risk – an adverse influence on asset values arising from political intervention in a specific country or region is managed through regular 

review of the asset distribution and through ensuring geographical diversification of investments within the managers; and

•  Custodian risk – the creditworthiness and ability of the custodians to settle trades on time and provide secure safekeeping of the assets under 

custody is managed by ongoing monitoring of the custodial arrangements against pre-agreed service levels and credit ratings.

26. Provisions

We make provisions when an obligation exists resulting from a past event, and it is probable that cash will be paid to settle it, but the exact amount 
of cash required can only be estimated.

The main estimates relate to environmental remediation and decommissioning costs for various sites we own or have owned and other provisions, 
including restructuring plans and lease contracts we have entered into that are now loss making. The evaluation of the likelihood of the contingent 
events has required best judgement by management regarding the probability of exposure to potential loss. Should circumstances change 
following unforeseeable developments, the likelihood could alter.

Provisions are recognised where a legal or constructive obligation exists at the reporting date, as a result of a past event, where the amount of the 
obligation can be reliably estimated and where the outflow of economic benefit is probable.

Provision is made for decommissioning and environmental costs, based on future estimated expenditures, discounted to present values. An initial 
estimate of decommissioning and environmental costs attributable to property, plant and equipment is recorded as part of the original cost of the 
related property, plant and equipment.

Changes in the provision arising from revised estimates, discount rates or changes in the expected timing of expenditure that relates to property, 
plant and equipment, are recorded as adjustments to their carrying value and depreciated prospectively over their remaining estimated useful 
economic lives; otherwise such changes are recognised in the income statement.

The unwinding of the discount is included within the income statement within finance costs.

The remediation expenditure in the UK relates to old gas manufacturing sites and also to electricity transmission sites. Cash flows are expected to be 
incurred until 2075 although the weighted average duration of the cash flows is 11 years. A number of estimation uncertainties affect the calculation 
of the provision, including the impact of regulation, the accuracy of site surveys, unexpected contaminants, transportation costs, the impact of 
alternative technologies and changes in the real discount rate. This provision incorporates our best estimate of the financial effect of these 
uncertainties, but future changes in any of the assumptions could materially impact the calculation of the provision. The undiscounted amount is the 
undiscounted best estimate of the liability having regard to these uncertainties.

The remediation expenditure in the US is expected to be incurred until 2069, of which the majority relates to three Superfund sites (being sites where 
hazardous substances are present as a result of the historic operations of manufactured gas plants in Brooklyn, New York). The weighted average 
duration of the cash flows is nine years. The uncertainties regarding the calculation of this provision are similar to those considered in respect of UK 
sites. Under the terms of our rate plans, we are entitled to recovery of environmental clean-up costs from rate payers.

Decommissioning provisions
The decommissioning provisions represent £174 million (2019: £80 million) of expenditure relating to asset retirement obligations estimated to be 
incurred until 2115, with additional amounts being recognised in the year relating to both interconnectors and other assets commissioned in the year. 
In addition, £74 million (2019: £90 million) of expenditure relating to the demolition of gas holders is estimated to be incurred until 2026.

Restructuring provisions
In 2019, a cost-efficiency and restructuring programme was undertaken in both our UK and US businesses, as detailed in note 5, which resulted in 
the recognition of a £125 million charge in that year. £39 million (2019: £42 million) was utilised during the current year, resulting in a closing provision 
of £35 million (2019: £83 million). 

Other provisions
Included within other provisions at 31 March 2020 are the following amounts:
•  £37 million (2019: £30 million) in respect of legacy provisions recognised following the sale of UK Gas Distribution; 
•  £31 million (2019: £29 million) in respect of onerous lease commitments and rates payable on surplus properties with expenditure expected to 

be incurred until 2039;

•  £164 million (2019: £164 million) of estimated liabilities in respect of past events insured by insurance subsidiary undertakings, including 

employer liability claims. In accordance with insurance industry practice, these estimates are based on experience from previous years, but we 
currently expect that cash flows will be incurred until 2049; and

•  £nil (2019: £13 million) in respect of obligations associated with investments in joint ventures and associates.

27. Share capital

Ordinary share capital represents the total number of shares issued which are publicly traded. We also disclose the number of treasury shares the 
Company holds, which are shares that the Company has bought itself, predominantly to actively manage scrip issuances and settle employee 
share option and reward plan liabilities.

Share capital is accounted for as an equity instrument. An equity instrument is any contract that includes a residual interest in the consolidated 
assets of the Company after deducting all its liabilities and is recorded at the proceeds received, net of direct issue costs, with an amount equal 
to the nominal amount of the shares issued included in the share capital account and the balance recorded in the share premium account.

1.   The issue of shares under the scrip dividend programme is considered to be a bonus issue under the terms of the Companies Act 2006, and the nominal value of the shares is charged to 

the share premium account.

The share capital of the Company consists of ordinary shares of 12204⁄473 pence nominal value each including ADSs. The ordinary shares and ADSs 
allow holders to receive dividends and vote at general meetings of the Company. The Company holds treasury shares but may not exercise any 
rights over these shares including the entitlement to vote or receive dividends. There are no restrictions on the transfer or sale of ordinary shares.

In line with the provisions of the Companies Act 2006, the Company has amended its Articles of Association and ceased to have authorised share 
capital.

Treasury shares
At 31 March 2020, the Company held 272 million (2019: 277 million) of its own shares. The market value of these shares as at 31 March 2020 was 
£2,574 million (2019: £2,359 million).

For the benefit of employees and in connection with the operation of the Company’s various share plans, the Company made the following 
transactions in respect of its own shares during the year ended 31 March 2020:

i.   During the year, 3 million (2019: 3 million) treasury shares were gifted to National Grid Employee Share Trusts and 2 million (2019: 3 million) 

treasury shares were re-issued in relation to employee share schemes, in total representing approximately 0.1% (2019: 0.2%) of the ordinary 
shares in issue as at 31 March 2020. The nominal value of these shares was £1 million (2019: £1 million) and the total proceeds received were 
£17 million (2019: £18 million). National Grid settles share awards under its Long Term Incentive Plan and the Save As You Earn scheme, by the 
transfer of treasury shares to its employee share trusts.

ii.   During the year, the Company made payments totalling £6 million (2019: £2 million) to National Grid Employee Share Trusts to enable the 

trustees to make purchases of National Grid plc shares to settle share awards in relation to all employee share plans and discretionary reward 
plans. The cost of such purchases is deducted from retained earnings in the period that the transaction occurs.

National Grid plc Annual Report and Accounts 2019/20Financial Statements28. Other equity reserves

Other equity reserves are different categories of equity as required by accounting standards and represent the impact of a number of our historical 
transactions.

Other equity reserves comprise the translation reserve (see accounting policy D in note 1), cash flow hedge reserve and the cost of hedging  
reserve (see note 32), available-for-sale reserve, debt instruments at fair value through other comprehensive income reserve (FVOCI debt) and  
equity investments at fair value through other comprehensive income reserve (FVOCI equity) (see note 15), the capital redemption reserve and  
the merger reserve. 

The merger reserve arose as a result of the application of merger accounting principles under the then prevailing UK GAAP, which under IFRS 1 was 
retained for mergers that occurred prior to the IFRS transition date. Under merger accounting principles, the difference between the carrying amount 
of the capital structure of the acquiring vehicle and that of the acquired business was treated as a merger difference and included within reserves. 
The merger reserve represents the difference between the carrying value of subsidiary undertaking investments and their respective capital 
structures following the Lattice demerger from BG Group plc and the 1999 Lattice refinancing.

The cash flow hedge reserve will amortise as the committed future cash flows from borrowings are paid or capitalised in fixed assets (as described in 
note 32). Cost of hedging, FVOCI debt, and FVOCI equity reserves arose as a result of the adoption of IFRS 9 on 1 April 2018. See note 15 for further 
detail on available-for-sale, FVOCI debt and FVOCI equity reserves and note 32 in respect of cost of hedging reserve.

As the amounts included in other equity reserves are not attributable to any of the other classes of equity presented, they have been disclosed 
as a separate classification of equity.

1.   The exchange adjustments recorded in the translation reserve comprise a gain of £545 million (2019: gain of £896 million; 2018: loss of £1,304 million) relating to the translation of foreign 
operations offset by a gain of £5 million (2019: loss of £550 million; 2018: gain of £800 million) relating to borrowings, cross-currency swaps and foreign exchange forward contracts used 
to hedge the net investment in non-sterling denominated subsidiaries.

2.   Following a review in the year, we have changed our presentation of spot foreign exchange movements on derivatives designated in cash flow hedges of foreign currency risk and interest 
rates. This has no net impact on the consolidated statement of comprehensive income. It has resulted in a prior year gross up to £166 million (2018: £277 million) to ‘Net losses taken to 
equity’ with an equal and offsetting gross up to ‘Transferred to profit or loss’.

29. Net debt

Net debt represents the amount of borrowings and overdrafts less cash, current financial investments and related financing derivatives.

Funding and liquidity risk management is carried out by the treasury function under policies and guidelines approved by the Finance Committee of 
the Board. The Finance Committee is responsible for the regular review and monitoring of treasury activity and for the approval of specific 
transactions, the authority for which fall outside the delegation of authority to management.

The primary objective of the treasury function is to manage our funding and liquidity requirements. A further important objective is to manage the 
associated financial risks, in the form of interest rate risk and foreign exchange risk, to within pre-authorised parameters. Details of the main risks 
arising from our financing and commodity hedging activities are included in note 32.

Investment of surplus funds, usually in short-term fixed deposits or placements with money market funds that invest in highly liquid instruments of 
high credit quality, is subject to our counterparty risk management policy.

(d) Reconciliation of changes in liabilities arising from financing activities
The table below reconciles changes in liabilities arising from financing activities, including both changes arising from cash flows and non-cash 
changes. Liabilities arising from financing activities are those for which cash flows were, or future cash flows will be, classified in the statement of 
cash flows within financing activities.

Following a review in the year, we have changed our accounting policy in relation to the presentation of certain derivatives in the cash flow statement 
to be presented as investing activities rather than financing activities (further detail is disclosed in note 1). The reclassified cash flows are in relation to 
derivatives associated with our net investment hedges, and given they are designated in a hedge relationship, the Group has decided to present 
them together with the underlying hedged item rather than as part of our overall financing activities.

As a result we have separately disclosed the reconciliation below, excluding derivatives associated with our net investment hedges, given that they 
are classified in the statement of cash flows within investing activities.

National Grid plc Annual Report and Accounts 2019/20Financial StatementsNotes to the consolidated financial statements 
– supplementary information

This section includes information that is important to enable a full understanding of our financial position, particularly areas of 
potential uncertainty that could affect us in the future.

We also include specific disclosures for Niagara Mohawk Power Corporation in accordance with various rules including Rule 3-10 
of Regulation S-X (a US SEC requirement), as they have issued public debt securities which have been guaranteed by National 
Grid plc. Additional disclosures have also been included in respect of the guarantor company. These disclosures are in lieu of 
publishing separate financial statements for these companies (see note 36 for further information).

30. Commitments and contingencies

Commitments are those amounts that we are contractually required to pay in the future as long as the other party meets its obligations. These 
commitments primarily relate to energy purchase agreements and contracts for the purchase of assets which, in many cases, extend over a long 
period of time. Commitments previously included operating lease commitments but on transition to IFRS 16, which was effective from 1 April 2019, 
substantially all lease commitments are included on the balance sheet as right-of-use assets (see note 13) and lease liabilities (see note 21). 
Therefore, only low-value leases and short-term leases are off-balance sheet commitments, both of which are immaterial. We also disclose any 
contingencies, which include guarantees that companies have given, where we pledge assets against current obligations that will remain for a 
specific period.

1.   Energy purchase commitments relate to contractual commitments to purchase electricity or gas that are used to satisfy physical delivery requirements to our customers or for energy that 
we use ourselves (i.e. normal purchase, sale or usage) and hence are accounted for as ordinary purchase contracts (see note 32(f)). Details of commodity contract derivatives that do not 
meet the normal purchase, sale or usage criteria, and hence are accounted for as derivative contracts, are shown in note 17(b).

2.   Included within total guarantees are guarantees to both joint ventures and Engineering, Procurement and Construction contractors regarding the construction of interconnectors of £358 

million (2019: £470 million).

3.  Includes guarantees to related parties.

Through the ordinary course of our operations, we are party to various litigation, claims and investigations. We do not expect the ultimate resolution 
of any of these proceedings to have a material adverse effect on our results of operations, cash flows or financial position.

(see note 16 for details).

5.  Dividends of £25 million (2019: £30 million) were received from BritNed Development Limited.
6.  Includes £32 million (2019: £24 million) of dividend income from Millennium Pipeline Company LLC. No dividends were received from Quadgas this year (2019: £133 million).

Details of investments in principal subsidiary undertakings, joint ventures and associates are disclosed in note 34, and information relating to pension 
fund arrangements is disclosed in note 25. For details of Directors’ and key management remuneration, refer to the Directors’ Remuneration Report 
on pages 88 – 108 and note 4(c). 

32. Financial risk management

Our activities expose us to a variety of financial risks including credit risk, liquidity risk, capital risk, currency risk, interest rate risk, inflation risk and 
commodity price risk. Our risk management programme focuses on the unpredictability of financial markets and seeks to minimise potential 
volatility of financial performance from these risks. We use financial instruments, including derivative financial instruments, to manage these risks.

Risk management related to financing activities is carried out by a central treasury department under policies approved by the Finance Committee of 
the Board. The objective of the treasury department is to manage funding and liquidity requirements, including managing associated financial risks, 
to within acceptable boundaries. The Finance Committee provides written principles for overall risk management, and written policies covering the 
following specific areas: foreign exchange risk, interest rate risk, credit risk, liquidity risk, use of derivative financial instruments and non-derivative 
financial instruments, and investment of excess liquidity. The Finance Committee has delegated authority to administer the commodity price risk 
policy and credit policy for US-based commodity transactions to the Energy Procurement Risk Management Committee and the National Grid USA 
Board of Directors. Details of key activities in the current year are set out in the Finance Committee report on page 82.

We have exposure to the following risks, which are described in more detail below:
•  credit risk;
•  liquidity risk;
•  currency risk;
•  interest rate risk;
•  commodity price risk; and
•  capital risk.

Where appropriate, derivatives and other financial instruments used for hedging currency and interest rate risk exposures are formally designated 
as fair value, cash flow or net investment hedges as defined in IFRS 9. Hedge accounting allows the timing of the profit or loss impact of qualifying 
hedging instruments to be recognised in the same reporting period as the corresponding impact of hedged exposures. To qualify for hedge 
accounting, documentation is prepared specifying the risk management objective and strategy, the component transactions and methodology 
used for measurement of effectiveness. 

182

National Grid plc Annual Report and Accounts 2019/20Financial Statements32. Financial risk management continued
Hedge accounting relationships are designated in line with risk management activities further described below. Categories designated at National 
Grid are as follows:
•  currency risk arising from our forecasted foreign currency transactions (capital expenditure or revenues) is designated in cash flow hedges;
•  currency risk arising from our net investments in foreign operations is designated in net investment hedges; and
•  currency and interest rate risk arising from borrowings are designated in cash flow or fair value hedges. 

Critical terms of hedging instruments and hedged items are transacted to match on a 1:1 ratio by notional values. Hedge ineffectiveness can 
nonetheless arise from inherent differences between derivatives and non-derivative instruments and other market factors including credit, 
correlations, supply and demand, and market volatilities. Ineffectiveness is recognised in the remeasurements component of finance income and 
costs (see note 6). Hedge accounting is discontinued when a hedging relationship no longer qualifies for hedge accounting.

Certain hedging instrument components are treated separately as costs of hedging with the gains and losses deferred in a component of other 
equity reserves and released systematically into profit or loss to correspond with the timing and impact of hedged exposures, or released in full to 
finance costs upon an early discontinuation of a hedging relationship.

Refer to sections (c) currency risk and (d) interest rate risk below for further details about hedge accounting.

(a) Credit risk
We are exposed to the risk of loss resulting from counterparties’ default on their commitments including failure to pay or make a delivery on a 
contract. This risk is inherent in our commercial business activities. Exposure arises from derivative financial instruments, deposits with banks and 
financial institutions, trade receivables and committed transactions with wholesale and retail customers.

Treasury credit risk
Counterparty risk arises from the investment of surplus funds and from the use of derivative financial instruments. As at 31 March 2020, the following 
limits were in place for investments held with banks and financial institutions:

Triple ‘A’ G7 sovereign entities (AAA)

Triple ‘A’ vehicles (AAA)

Triple ‘A’ range institutions and non-G7 sovereign entities (AAA)

Double ‘A+’ G7 sovereign entities (AA+)

The maximum limit applies to all transactions, including long-term transactions. The long-term limit applies to transactions which mature in  
more than 12 months’ time.

As at 31 March 2020 and 2019, we had a number of exposures to individual counterparties. In accordance with our treasury policies,  
counterparty credit exposure utilisations are monitored daily against the counterparty credit limits. Counterparty credit ratings and market  
conditions are reviewed continually with limits being revised and utilisation adjusted, if appropriate. Management does not expect any  
significant losses from non-performance by these counterparties. Further information on financial investments subject to impairment  
provisioning is included in note 15.

Commodity credit risk
The credit policy for US-based commodity transactions is owned by the Finance Committee to the Board, which establishes controls and 
procedures to determine, monitor and minimise the credit exposure to counterparties.

Wholesale and retail credit risk
Our principal commercial exposure in the UK is governed by the credit rules within the regulated codes: Uniform Network Code and Connection  
and Use of System Code. These set out the level of credit relative to the RAV for each credit rating. In the US, we are required to supply electricity 
and gas under state regulations. Our policies and practices are designed to limit credit exposure by collecting security deposits prior to providing 
utility services, or after utility service has commenced if certain applicable regulatory requirements are met. Collection activities are managed  
on a daily basis. Sales to retail customers are usually settled in cash, cheques, electronic bank payments or by using major credit cards. We are 
committed to measuring, monitoring, minimising and recording counterparty credit risk in our wholesale business. The utilisation of credit limits 
is regularly monitored, and collateral is collected against these accounts when necessary. In March 2020, the Group’s US distribution business 
ceased certain cash collection and termination activities in response to regulatory instructions following the COVID-19 pandemic. This has resulted 
in the recognition of expected credit losses as at 31 March 2020 (see note 19 for further details).

Offsetting financial assets and liabilities
The following tables set out our financial assets and liabilities which are subject to offset and to enforceable master netting arrangements or similar 
agreements. The tables show the amounts which are offset and reported net in the statement of financial position. Amounts which cannot be offset 
under IFRS, but which could be settled net under terms of master netting arrangements if certain conditions arise, and with collateral received or 
pledged, are shown to present National Grid’s net exposure.

Financial assets and liabilities on different transactions are only reported net if the transactions are with the same counterparty, a currently 
enforceable legal right of offset exists, and the cash flows are intended to be settled on a net basis.

Amounts which do not meet the criteria for offsetting on the statement of financial position, but could be settled net in certain circumstances, 
principally relate to derivative transactions under ISDA agreements, where each party has the option to settle amounts on a net basis in the event of 
default of the other party.

Commodity contract derivatives that have not been offset on the balance sheet may be settled net in certain circumstances under ISDA or North 
American Energy Standards Board (NAESB) agreements.

For bank account balances and bank overdrafts, the ‘Gross amounts offset’ under cash pooling arrangements is £23 million as at 31 March 2020 
(2019: £19 million). Our UK bank accounts for National Grid subsidiaries participate in GBP, EUR and USD Composite Accounting System overdraft 
facilities subject to offsetting gross and net overdraft limits. In the US, no offsetting arrangements exist, and cash transactions are settled through 
Service Company bank accounts with subsequent intercompany payables and receivables reported by subsidiaries with the Service Company.

The gross amounts offset for trade payables and receivables, which are subject to general terms and conditions, are insignificant.

(b) Liquidity risk
Our policy is to determine our liquidity requirements by the use of both short-term and long-term cash flow forecasts. These forecasts are 
supplemented by a financial headroom analysis which is used to assess funding requirements for at least a 24-month period and maintain 
adequate liquidity for a continuous 12-month period.

We believe our contractual obligations, including those shown in commitments and contingencies in note 30, can be met from existing cash 
and investments, operating cash flows and other financing that we reasonably expect to be able to secure in the future, together with the use 
of committed facilities if required.

Our debt agreements and banking facilities contain covenants, including those relating to the periodic and timely provision of financial information 
by the issuing entity and financial covenants such as restrictions on the level of subsidiary indebtedness. Failure to comply with these covenants, 
or to obtain waivers of those requirements, could in some cases trigger a right, at the lender’s discretion, to require repayment of some of our debt 
and may restrict our ability to draw upon our facilities or access the capital markets.

1.   The interest on borrowings is calculated based on borrowings held at 31 March without taking account of future issues. Floating rate interest is estimated using a forward interest rate curve 

as at 31 March. Payments are included on the basis of the earliest date on which the Company can be required to settle.

2.   The receipts and payments line items for derivatives comprise gross undiscounted future cash flows, after considering any contractual netting that applies within individual contracts. Where 
cash receipts and payments within a derivative contract are settled net, and the amount to be received/(paid) exceeds the amount to be paid/(received), the net amount is presented within 
derivative receipts/(payments).

32. Financial risk management continued
(c) Currency risk
National Grid operates internationally with mainly the pound sterling as the functional currency for the UK companies and the US dollar for the 
US businesses. Currency risk arises from three major areas: funding activities, capital investment and related revenues, and holdings in foreign 
operations. This risk is managed using financial instruments including derivatives as approved by policy, typically cross-currency interest rate swaps, 
foreign exchange swaps and forwards.

Funding activities – our policy is to borrow in the most advantageous market available. Foreign currency funding gives rise to risk of volatility in the 
amount of functional currency cash to be repaid. This risk is reduced by swapping principal and interest back into the functional currency of the 
issuer. All foreign currency debt and transactions are hedged except where they provide a natural offset to assets elsewhere in the Group. 

Capital investment and related revenues – capital projects often incur costs or generate revenues in a foreign currency, most often euro transactions 
done by the UK business. Our policy for managing foreign exchange transaction risk is to hedge contractually committed foreign currency cash flows 
over a prescribed minimum size, typically by buying euro forwards to hedge future expenditure, and selling euro forwards to hedge future revenues. 
For hedges of forecast cash flows our policy is to hedge a proportion of highly probable cash flows. 

Holdings in foreign operations – we are exposed to fluctuations on the translation into pounds sterling of our foreign operations. The policy for 
managing this translation risk is to issue foreign currency debt or to replicate foreign debt using derivatives that pay cash flows in the currency of the 
foreign operation. The primary managed exposure arises from dollar denominated assets and liabilities held by our US operations, with a smaller 
euro exposure in respect of joint venture investments.

The carrying amounts of other financial instruments are denominated in the above currencies, which in most instances are the functional currency 
of the respective subsidiaries. Our exposure to dollars is due to activities in our US subsidiaries. We do not have any other significant exposure to 
currency risk on these balances.

Hedge accounting for currency risk
Where available, derivatives transacted for hedging are designated for hedge accounting. Economic offset is qualitatively determined because the critical terms 
(currency and volume) of the hedging instrument match the hedged exposure. If a forecast transaction was no longer expected to occur, the cumulative gain or 
loss previously reported in equity would be transferred to the income statement. This has not occurred in the current or comparative years.

Cash flow hedging of currency risk of capital expenditure and revenues is designated as hedging the exposure to movements in the spot translation 
rates only; the timing of forecasted transactions is not designated as a hedged risk. Gains and losses on hedging instruments arising from forward 
points and foreign currency basis spreads are excluded from designation and are recognised immediately in profit or loss, along with any hedge 
ineffectiveness. On recognition of the hedged purchase or sale in the financial statements, the associated hedge gains and losses, deferred in the 
cash flow hedge reserve in other equity reserves, are transferred out of reserves and included with the recognition of the underlying transaction. 
Where a non-financial asset or a non-financial liability results from a forecast transaction or firm commitment being hedged, the amounts deferred in 
reserves are included directly in the initial measurement of that asset or liability.

Net investment hedging is also designated as hedging the exposure to movements in spot translation rates only: spot-related gains and losses on 
hedging instruments are presented in the cumulative translation reserve within other equity reserves to offset gains or losses on translation of the 
hedged balance sheet exposure. Any ineffectiveness is recognised immediately in the income statement. Gains and losses arising from forward 
points and foreign currency basis spreads are excluded from designation and are treated as a cost of hedging, deferred initially in other equity 
reserves and released into profit or loss over the life of the hedging relationship. Amounts deferred in the cumulative translation reserve with respect 
to net investment hedges are subsequently recognised in the income statement in the event of disposal of the overseas operations concerned. Any 
remaining amounts deferred in the cost of hedging reserve are also released to the income statement.

Hedges of foreign currency funding are designated as cash flow hedges or fair value hedges of forward exchange risk (hedging both currency and 
interest rate risk together, where applicable). Hedge accounting for funding is described further in the interest rate risk section below.

186

National Grid plc Annual Report and Accounts 2019/20Financial Statements32. Financial risk management continued
(d) Interest rate risk
National Grid’s interest rate risk arises from our long-term borrowings. Our interest rate risk management policy is to seek to minimise total financing 
costs (being interest costs and changes in the market value of debt). Hedging instruments principally consist of interest rate and cross-currency 
swaps that are used to translate foreign currency debt into functional currency and to adjust the proportion of fixed-rate and floating-rate in the 
borrowings portfolio to within a range set by the Finance Committee of the Board. The benchmark interest rates hedged are currently based on 
LIBOR. 

LIBOR is being replaced as an interest rate benchmark by alternative reference rates in certain currencies including our functional currencies, USD 
and GBP, and foreign currencies in which we operate. This impacts contracts including financial liabilities that pay LIBOR-based cash flows, and 
derivatives that receive or pay LIBOR-based cash flows. The change in benchmark also affects discount rates which can impact valuations. We are 
managing the risk by planning to replace LIBOR cash flows with alternative reference rates on our affected contracts. 

We also consider inflation risk and hold some inflation-linked borrowings. We believe that these provide a partial economic offset to the inflation risk 
associated with our UK inflation-linked revenues.

The table in note 21 sets out the carrying amount, by contractual maturity, of borrowings that are exposed to interest rate risk before taking into 
account interest rate swaps.

1.  Represents financial instruments which are not directly affected by interest rate risk, such as investments in equity or other similar financial instruments.

Hedge accounting for interest rate risk
Borrowings paying variable or floating-rates expose National Grid to cash flow interest rate risk, partially offset by cash held at variable rates. Where a 
hedging instrument results in paying a fixed-rate, it is designated as a cash flow hedge because it has reduced the cash flow volatility of the hedged 
borrowing. Changes in the fair value of the derivative are initially recognised in other comprehensive income as gains or losses in the cash flow hedge 
reserve, with any ineffective portion recognised immediately in the income statement. 

Borrowings paying fixed-rates expose National Grid to fair value interest rate risk. Where the hedging instrument pays a floating-rate, it is designated 
as a fair value hedge because it has reduced the fair value volatility of the borrowing. Changes in the fair value of the derivative and changes in the fair 
value of the hedged item in relation to the risk being hedged are both adjusted on the balance sheet and offset in the income statement to the extent 
the fair value hedge is effective, with the residual difference remaining as ineffectiveness.

Both types of hedges are designated as hedging the currency and interest rate risk arising from changes in forward points. Amounts accumulated in 
the cash flow hedge reserve (cash flow hedges only) and the deferred cost of hedging reserve (both cash flow and fair value hedges) are reclassified 
from reserves to the income statement on a systematic basis as hedged interest expense is recognised. Adjustments made to the carrying value of 
hedged items in fair value hedges are similarly released to the income statement to match the timing of the hedged interest expense.

When hedge accounting is discontinued, any remaining cumulative hedge accounting balances continue to be released to the income statement to 
match the impact of outstanding hedged items. Any remaining amounts deferred in the cost of hedging reserve are released immediately to the 
income statement as finance costs.

The Group early-adopted IFRS Interest Rate Benchmark Reform amendments related to hedge accounting, with effect from 1 April 2019. The 
amendments allow existing hedge designations to continue unchanged during the period of uncertainty relating to the timing and method of 
benchmark migrations.

The amendments will be applied until the earlier point in time where affected cash flows are amended, the relationship is formally discontinued,  
and any cash flow hedge reserve balance has been released, or formal market conventions ending uncertainty are published and widely adopted.  
If amended cash flows do not cause a hedging relationship to be discontinued, then the amendments will cease to be applied only when that 
relationship is discontinued under IFRS 9. 

The IFRS amendments impact fair value and cash flow hedges of interest rate risk and related hedging instruments, and certain net investment 
hedges that use cross-currency interest rate swaps to pay a foreign currency floating rate and receive a functional currency floating rate. The  
notional values of hedging instruments, for each type of hedging relationship impacted, are shown in the hedge accounting tables in note 32(e). 
These amounts also correspond to the exposures designated as hedged.

1.   Following a review in the year, we have changed our presentation of spot foreign exchange movements on derivatives designated in cash flow hedges of foreign currency risk and interest 
rates. This has no net impact on the consolidated statement of comprehensive income. It has resulted in a prior year gross up of £166 million to net losses in respect of cash flow hedges 
with an equal and offsetting gross up to transferred to profit and loss in respect of cash flow hedges. 

2.   The use of derivatives may entail a derivative transaction qualifying for more than one hedge type designation under IFRS 9. Therefore, the derivative amounts in the table above are grossed

National Grid plc Annual Report and Accounts 2019/20Financial Statements32. Financial risk management continued
(f) Commodity price risk
We purchase electricity and gas to supply our customers in the US and to meet our own energy needs. Substantially all our costs of purchasing 
electricity and gas for supply to customers are recoverable at an amount equal to cost. The timing of recovery of these costs can vary between 
financial periods leading to an under- or over-recovery within any particular year that can lead to large fluctuations in the income statement. We follow 
approved policies to manage price and supply risks for our commodity activities.

Our energy procurement risk management policy and delegations of authority govern our US commodity trading activities for energy transactions. 
The purpose of this policy is to ensure we transact within pre-defined risk parameters and only in the physical and financial markets where we or  
our customers have a physical market requirement. In addition, state regulators require National Grid to manage commodity risk and cost volatility 
prudently through diversified pricing strategies. In some jurisdictions we are required to file a plan outlining our strategy to be approved by regulators. 
In certain cases, we might receive guidance with regard to specific hedging limits.

Energy purchase contracts for the forward purchase of electricity or gas that are used to satisfy physical delivery requirements to customers, or for 
energy that the Group uses itself, meet the expected purchase or usage requirements of IFRS 9. They are, therefore, not recognised in the financial 
statements until they are realised. Disclosure of commitments under such contracts is made in note 30.

US states have introduced a variety of legislative requirements with the aim of increasing the proportion of our electricity that is derived from 
renewable or other forms of clean energy. Annual compliance filings regarding the level of Renewable Energy Certificates (and other similar 
environmental certificates) are required by the relevant department of utilities. In response to the legislative requirements, National Grid has entered 
into long-term, typically fixed-price, energy supply contracts to purchase both renewable energy and environmental certificates. We are entitled to 
recover all costs incurred under these contracts through customer billing.

Under IFRS, where these supply contracts are not accounted for as finance leases, they are considered to comprise two components, being a 
forward purchase of power at spot prices, and a forward purchase of environmental certificates at a variable price (being the contract price less 
the spot power price). With respect to our current contracts, neither of these components meets the requirement to be accounted for as a derivative. 
The environmental certificates are currently required for compliance purposes, and at present there are no liquid markets for these attributes. 
Accordingly, this component meets the expected purchase or usage exemption of IFRS 9. We expect to enter into an increasing number of these 
contracts, in order to meet our compliance requirements in the short to medium term. It is possible that in future, if and when liquid markets develop, 
and to the extent that we are in receipt of environmental certificates in excess of our required levels, this exemption may cease to apply, and we may 
be required to account for forward purchase commitments for environmental certificates as derivatives at fair value through profit and loss.

(g) Fair value analysis
Included in the statement of financial position are financial instruments which are measured at fair value. These fair values can be categorised into 
hierarchy levels that are representative of the inputs used in measuring the fair value. The best evidence of fair value is a quoted price in an actively 
traded market. In the event that the market for a financial instrument is not active, a valuation technique is used.

1.  Our Level 3 investments include investments relating to Sunrun Neptune 2016 LLC accounted for at FVTPL.
2.  Contingent consideration relates to the acquisition of Geronimo (see note 38).

Level 1:

Level 2:

Financial instruments with quoted prices for identical instruments in active markets.

Financial instruments with quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments 
in inactive markets, and financial instruments valued using models where all significant inputs are based directly or indirectly on 
observable market data.

Level 3:

Financial instruments valued using valuation techniques where one or more significant inputs are based on unobservable market data.

Our Level 1 financial investments and liabilities held at fair value are valued using quoted prices from liquid markets.

Our Level 2 financial investments held at fair value are valued using quoted prices for similar instruments in active markets, or quoted prices for 
identical or similar instruments in inactive markets. Alternatively, they are valued using models where all significant inputs are based directly or 
indirectly on observable market data. 

Our Level 2 financing derivatives include cross-currency, interest rate and foreign exchange derivatives. We value these by discounting all future  
cash flows by externally sourced market yield curves at the reporting date, taking into account the credit quality of both parties. These derivatives 
can be priced using liquidly traded interest rate curves and foreign exchange rates, and therefore we classify our vanilla trades as Level 2 under  
the IFRS 13 framework. 

Our Level 2 commodity contract derivatives include over-the-counter gas and power swaps as well as forward physical gas deals. We value our 
contracts based on market data obtained from the New York Mercantile Exchange (NYMEX) and the Intercontinental Exchange (ICE) where monthly 
prices are available. We discount based on externally sourced market yield curves at the reporting date, taking into account the credit quality of both 
parties and liquidity in the market. Our commodity contracts can be priced using liquidly traded swaps. Therefore, we classify our vanilla trades as 
Level 2 under the IFRS 13 framework.

Our Level 3 financing derivatives include cross-currency swaps, inflation-linked swaps and equity options, where the market is illiquid. In valuing 
these instruments, we use in-house valuation models and obtain external valuations to support each reported fair value.

Our Level 3 commodity contract derivatives primarily consist of our forward purchases of electricity and gas that we value using proprietary models. 
Derivatives are classified as Level 3 where significant inputs into the valuation technique are neither directly nor indirectly observable (including our 
own data, which are adjusted, if necessary, to reflect the assumptions market participants would use in the circumstances).

Our Level 3 investments include equity instruments accounted for at fair value through profit and loss. These equity holdings are part of our corporate 
venture capital portfolio held by National Grid Partners and comprise a series of small unquoted investments where prices or valuation inputs are 
unobservable. These investments are either recently acquired or there have been recent funding rounds with third parties and therefore the valuation 
is based on the latest transaction price and any subsequent investment-specific adjustments.

Our Level 3 investments in associates include our investment in Sunrun Neptune 2016 LLC, which is accounted for at fair value. The investment is fair 
valued by discounting expected cash flows using a weighted average cost of capital specific to Sunrun Neptune 2016 LLC.

In light of the current ongoing impact of the COVID-19 pandemic, the valuations of certain assets and liabilities can be more subjective. While there 
have been significant movements in market indices, we are satisfied that there has been no significant impact on the fair values of our financial 
instruments measured at fair value, and that any impact is reflected in the fair values in the table above.

1.  Level 3 commodity price sensitivity is included within the sensitivity analysis disclosed in note 35.
2.  A reasonably possible change in assumption of other Level 3 derivative financial instruments is unlikely to result in a material change in fair values.
3.  The investments acquired in the period were on market terms, and sensitivity is considered insignificant at 31 March 2020.

The impacts disclosed above were considered on a contract-by-contract basis with the most significant unobservable inputs identified.

32. Financial risk management continued
(h) Capital risk management
The capital structure of the Group consists of shareholders’ equity, as disclosed in the consolidated statement of changes in equity, and net debt 
(note 29). National Grid’s objectives when managing capital are: to safeguard our ability to continue as a going concern; to remain within regulatory 
constraints of our regulated operating companies; and to maintain an efficient mix of debt and equity funding thus achieving an optimal capital 
structure and cost of capital. We regularly review and manage the capital structure as appropriate in order to achieve these objectives.

Maintaining appropriate credit ratings for our operating and holding companies is an important aspect of our capital risk management strategy and 
balance sheet efficiency. We monitor our balance sheet efficiency using several metrics including retained cash flow/net debt (RCF), regulatory 
gearing and interest cover. For the year ended 31 March 2020, these metrics for the Group were 9.2% (2019: 9.4%), 63% (2019: 66%) and 4.1x (2019: 
4.4x), respectively – see pages 28 and 244 – 245. We believe these are consistent with the current credit ratings for National Grid plc in respect of the 
main companies of the Group, based on guidance from the rating agencies.

We monitor the RAV gearing within NGET and the regulated transmission businesses within NGG. This is calculated as net debt expressed as a 
percentage of RAV, and indicates the level of debt employed to fund our UK regulated businesses. It is compared with the level of RAV gearing 
indicated by Ofgem as being appropriate for these businesses, at around 60% to 62.5%. We also monitor net debt as a percentage of rate base for 
our US operating companies, comparing this with the allowed rate base gearing inherent within each of our agreed rate plans, typically around 50%.

The majority of our regulated operating companies in the US and the UK are subject to certain restrictions on the payment of dividends by 
administrative order, contract and/or licence. The types of restrictions that a company may have that would prevent a dividend being declared or 
paid unless they are met include:
•  dividends must be approved in advance by the relevant US state regulatory commission;
•  subsidiary must have at least two recognised rating agency credit ratings of at least investment grade;
•  dividends must be limited to cumulative retained earnings, including pre-acquisition retained earnings;
•  the securities of National Grid plc must maintain an investment grade credit rating, and if that rating is the lowest investment grade bond rating 

it cannot have a negative watch/review for downgrade notice by a credit rating agency;
•  the subsidiary must not carry on any activities other than those permitted by the licences;
•  the subsidiary must not create any cross-default obligations or give or receive any intra-group cross-subsidies; and
•  the percentage of equity compared with total capital of the subsidiary must remain above certain levels.

There is a further restriction relating only to The Narragansett Electric Company, which is required to maintain its consolidated net worth above 
certain levels.

These restrictions are subject to alteration in the US as and when a new rate case or rate plan is agreed with the relevant regulatory bodies for each 
operating company and in the UK through the normal licence review process.

As most of our business is regulated, at 31 March 2020 the majority of our net assets are subject to some of the restrictions noted above. These 
restrictions are not considered to be significantly onerous, nor do we currently expect they will prevent the planned payment of dividends in future in 
line with our dividend policy.

All the above requirements are monitored on a regular basis in order to ensure compliance. The Group has complied with all externally imposed 
capital requirements to which it is subject.

National Grid plc Annual Report and Accounts 2019/20Financial Statements33. Borrowing facilities

To support our liquidity requirements and provide backup to commercial paper and other borrowings, we agree loan facilities with financial 
institutions over and above the value of borrowings that may be required. These committed credit facilities have never been drawn, and our 
undrawn amounts are listed below.

At 31 March 2020, we had bilateral committed credit facilities of £5,495 million (2019: £5,463 million). In addition, we had committed credit facilities 
from syndicates of banks of £277 million at 31 March 2020 (2019: £264 million). All committed credit facilities were undrawn in 2020 and 2019. An 
analysis of the maturity of these undrawn committed facilities is shown below:

million) is available as backup to specific US borrowings. £1,923 million of the undrawn bilateral facilities due to mature in one to two years, were 
renegotiated between 1 April and 17 June 2020 with new expiry dates to June 2024. Of the £1,887 million of undrawn committed borrowings facilities 
due to expire within four to five years, £110 million was renegotiated before 31 March 2020, with the expiry extended by a further year, with effect 
from 1 June 2020.

For the separately regulated business of National Grid Electricity System Operator Limited, the Group has a facility of £550 million (2019: £550 
million). This facility is not available as Group general liquidity support and is not represented in the table above.

In addition to the above, the Group has Export Credit Agreements (ECAs) totalling £901 million (2019: £859 million), of which £233 million (2019: £510 
million) is undrawn. Subsequent to the year end, two new ECAs totalling £598 million have been made available and have not been drawn.

34. Subsidiary undertakings, joint ventures and associates 

While we present consolidated results in these financial statements as if we were one company, our legal structure is such that there are a number 
of different operating and holding companies that contribute to the overall result. This structure has evolved through acquisitions as well as 
regulatory requirements to have certain activities within separate legal entities.

Subsidiary undertakings
A list of the Group’s subsidiaries as at 31 March 2020 is given below. The entire share capital of subsidiaries is held within the Group except where 
the Group’s ownership percentages are shown. These percentages give the Group’s ultimate interest and therefore allow for the situation where 
subsidiaries are owned by partly owned intermediate subsidiaries. Where subsidiaries have different classes of shares, this is largely for historical 
reasons, and the effective percentage holdings given represent both the Group’s voting rights and equity holding. Shares in National Grid (US) 
Holdings Limited, National Grid Holdings One plc and NGG Finance plc are held directly by National Grid plc. All other holdings in subsidiaries 
are owned by other subsidiaries within the Group. All subsidiaries are consolidated in the Group’s financial statements.

Principal Group companies are identified in bold. These companies are incorporated and principally operate in the countries under which they are 
shown.

National Grid plc Annual Report and Accounts 2019/20Financial Statements35. Sensitivities

In order to give a clearer picture of the impact on our results or financial position of potential changes in significant estimates and assumptions, the 
following sensitivities are presented. These sensitivities are based on assumptions and conditions prevailing at the year-end and should be used 
with caution. The effects provided are not necessarily indicative of the actual effects that would be experienced because our actual exposures are 
constantly changing.

The sensitivities in the tables below show the potential impact in the income statement (and consequential impact on net assets) for a reasonably 
possible range of different variables each of which have been considered in isolation (i.e. with all other variables remaining constant). There are a 
number of these sensitivities which are mutually exclusive, and therefore if one were to happen, another would not, meaning a total showing how 
sensitive our results are to these external factors is not meaningful.

The sensitivities included in the tables below broadly have an equal and opposite effect if the sensitivity increases or decreases by the same amount 
unless otherwise stated.

(a) Sensitivities on areas of estimation uncertainty
The table below sets out the sensitivity analysis for certain areas of estimation uncertainty set out in note 1E. These estimates are those that have a 
significant risk of resulting in a material adjustment to the carrying values of assets and liabilities in the next year. Note that the sensitivity analysis for 
the useful economic lives of our gas network assets is included in note 13.

Pensions and other post-retirement benefit liabilities (pre-tax)¹:

UK discount rate change of 0.5%²

US discount rate change of 0.5%²

UK RPI rate change of 0.5%³

UK long-term rate of increase in salaries change of 0.5%

US long-term rate of increase in salaries change of 0.5%

UK change of one year to life expectancy at age 654

US change of one year to life expectancy at age 65

Assumed US healthcare cost trend rates change of 1%

Pension assets:

Change in value of unquoted equities by 10%

Change in value of unquoted properties by 10%

Change in value of unquoted diversified alternatives by 10%

Environmental provision:

10% change in estimated future cash flows

1.   The changes shown are a change in the annual pension or other post-retirement benefit service charge and change in the defined benefit obligations.
2.   A change in the discount rate is likely to occur as a result of changes in bond yields and as such would be expected to be offset to a significant degree by a change in the value of the bond 
assets held by the plans. In the UK, there would also be a £205 million net assets offset from the buy-in policies purchased in the year, where the accounting value of the buy-in asset is set 
equal to the associated liabilities.

3.   The projected impact resulting from a change in RPI reflects the underlying effect on pensions in payment, pensions in deferment and resultant increases in salary assumptions. The buy-in 

policies purchased during the year would have a £152 million net assets offset to the above.

4.  In the UK, the buy-in policies purchased during the year, and the longevity swap entered into previously, would have a £223 million net assets offset to the above.

Pensions and other post-retirement benefits assumptions
Sensitivities have been prepared to show how the defined benefit obligations and annual service costs could potentially be impacted by changes 
in the relevant actuarial assumption that were reasonably possible as at 31 March 2020. In preparing sensitivities, the potential impact has been 
calculated by applying the change to each assumption in isolation and assuming all other assumptions remain unchanged. This is with the exception 
of RPI in the UK where the corresponding change to increases to pensions in payment, increases to pensions in deferment and increases in salary 
are recognised.

35. Sensitivities continued
(b) Sensitivities on financial instruments
We are further required to show additional sensitivity analysis under IFRS 7 and these are shown separately in the subsequent table due to the 
additional assumptions that are made in order to produce meaningful sensitivity disclosures.

Our net debt as presented in note 29 is sensitive to changes in market variables, primarily being UK and US interest rates, the UK RPI and the dollar 
to sterling exchange rate. These impact the valuation of our borrowings, deposits and derivative financial instruments. The analysis illustrates the 
sensitivity of our financial instruments to reasonably possible changes in these market variables.

The following main assumptions were made in calculating the sensitivity analysis for continuing operations:
•  the amount of net debt, the ratio of fixed to floating interest rates of the debt and derivatives portfolio, and the proportion of financial 

instruments in foreign currencies are all constant and on the basis of the hedge designations in place at 31 March 2020 and 2019 respectively;
•  the statement of financial position sensitivity to interest rates relates to items presented at their fair values: derivative financial instruments; our 

investments measured at fair value through profit and loss (FVTPL) and fair value through other comprehensive income; and our liability 
measured at FVTPL. Further debt and other deposits are carried at amortised cost and so their carrying value does not change as interest 
rates move;

•  the sensitivity of interest to movements in interest rates is calculated on net floating rate exposures on debt, deposits and derivative 

instruments;

•  changes in the carrying value of derivatives from movements in interest rates of designated cash flow hedges are assumed to be recorded fully 

within equity; and

•  changes in the carrying value of derivative financial instruments designated as net investment hedges from movements in interest rates are 
presented in equity as costs of hedging, with a one-year release to the income statement. The impact of movements in the dollar to sterling 
exchange rate are recorded directly in equity.

Financial risk (post-tax):

UK RPI change of 0.5%¹

UK interest rates change of 0.5%

US interest rates change of 0.5%

US dollar exchange rate change of 10%²

1.  Excludes sensitivities to LPI curve. Further details on sensitivities are provided in note 32(g).
2.   The other equity reserves impact does not reflect the exchange translation in our US subsidiaries’ net assets. It is estimated this would change by £1,319 million (2019: £1,119 million) in the 

opposite direction if the dollar exchange rate changed by 10%.

Our commodity contract derivatives are sensitive to price risk. Additional sensitivities in respect to commodity price risk and to our derivative fair 
values are as follows:

Commodity price risk (post-tax):

10% increase in commodity prices

10% decrease in commodity prices

Assets and liabilities carried at fair value (post-tax):

National Grid plc Annual Report and Accounts 2019/20Financial Statements36. Additional disclosures in respect of guaranteed securities 

We have preferred shares that are listed on a US national securities exchange and are guaranteed by other companies in the Group. These guarantors 
commit to honour any liabilities should the company issuing the debt have any financial difficulties. In order to provide debt holders with information on 
the financial stability of the companies providing the guarantees, we are required to disclose individual financial information for these companies. We 
have chosen to include this information in the Group financial statements rather than submitting separate stand-alone financial statements.

Niagara Mohawk Power Corporation, a wholly owned subsidiary of the Group, has issued preferred shares that are listed on a US national securities 
exchange and are guaranteed by National Grid plc. In order to provide preferred shareholders with information on the financial stability of the 
company providing the guarantee, we are required to disclose individual financial information for these companies. We have chosen to include this 
information in the Group financial statements rather than submitting separate stand-alone financial statements.

The following summarised financial information is given in respect of Niagara Mohawk Power Corporation as a result of National Grid plc’s guarantee, 
dated 29 October 2007, of Niagara Mohawk Power Corporation’s 3.6% and 3.9% issued preferred shares, which amount to £29 million. National 
Grid plc’s guarantee of Niagara Mohawk Power Corporation’s preferred shares is full and unconditional. There are no restrictions on the payment of 
dividends by Niagara Mohawk Power Corporation or limitations on National Grid plc’s guarantee of the preferred shares, and there are no factors that 
may affect payments to holders of the guaranteed securities. 

The following summarised financial information for National Grid plc and Niagara Mohawk Power Corporation is presented on a combined basis and 
is intended to provide investors with meaningful and comparable financial information, and is provided pursuant to the early adoption of Rule 13-01 of 
Regulation S-X in lieu of the separate financial statements of Niagara Mohawk Power Corporation.

Summarised financial information is presented, on a combined basis, as at 31 March 2020. The combined amounts are presented under IFRS 
measurement principles. Inter-company transactions have been eliminated. Investments in other non-issuer and non-guarantor subsidiaries are 
included at cost, subject to impairment.

37. Transition to new accounting standards
(a) Transition to IFRS 16
The Group has adopted IFRS 16 ‘Leases’, with effect from 1 April 2019. IFRS 16 introduces a single lease accounting model for lessees (rather than 
the current distinction between operating and finance leases). A contract is, or contains, a lease, if it provides the right to control the use of an 
identified asset for a specific period of time in exchange for consideration. The new standard results in our operating leases being accounted for in 
the consolidated statement of financial position as ‘right-of-use’ assets with corresponding lease liabilities also recognised. It therefore increases 
both our assets and liabilities (including net debt). It also changes the timing and presentation in the consolidated income statement as it results in an 
increase in finance costs and depreciation largely offset by a reduction in the previously straight-line operating costs. 

Transition options
We have applied IFRS 16 using the modified retrospective approach. Comparatives have not been restated on adoption. Instead, on the opening 
balance sheet date, right-of-use assets (net of accrued rent or rent-free periods, and reported within property, plant and equipment), additional lease 
liabilities (reported within borrowings) and any associated deferred tax have been recognised, with no cumulative transition adjustment to reflect 
through retained earnings. For short-term leases (lease term of 12 months or less) and leases of low-value assets (such as computers), the Group 
continues to recognise a lease expense on a straight-line basis as permitted by IFRS 16.

– supplementary information continued

37. Transition to new accounting standards continued
(a) Transition to IFRS 16 continued
We elected to apply the practical expedient to grandfather our previous assessments of whether contracts were previously accounted for as a lease, 
as permitted by the standard, instead of reassessing all significant contracts as at the date of initial application to determine whether they met the 
IFRS 16 definition of a lease. 

We have elected to apply the practical expedient on transition, which permits right-of-use assets to be measured at an amount equal to the lease 
liability on adoption of the standard (adjusted for any prepaid or accrued lease expenses). 

In addition, we have also elected the option to adjust the carrying amounts of the right-of-use assets as at 1 April 2019 for any onerous lease 
provisions that had been recognised on the Group consolidated statement of financial position as at 31 March 2019, rather than performing 
impairment assessments on transition. 

Impact of transition
At 31 March 2019, the Group disclosed non-cancellable operating lease commitments of £0.3 billion, of which the majority were in the US. A further 
£0.4 billion of lease liabilities were recognised due to the requirement in IFRS 16 to recognise lease liabilities for the term that we are reasonably 
certain to exercise lease extension or lease termination options for, rather than only for the period of the minimum contractual term that was used in 
determining our lease liability commitments. This was partially offset by the £0.2 billion impact of discounting our lease liabilities at the incremental 
borrowing rate for each lease. The weighted average discount rate applied to lease liabilities recognised on the transition date was 2.8%.There were 
some immaterial short-term and low-value leases, which will be recognised on a straight-line basis as an expense in the consolidated income 
statement over the remaining lease term. 

As a result, the Group has recognised additional right-of-use assets of £0.5 billion and lease liabilities (which are included within net debt) of £0.5 
billion at 1 April 2019. No additional net deferred tax has arisen. The transition adjustment is in addition to the £270 million of finance leases already 
recognised on the consolidated statement of financial position under IAS 17. There has been no impact on net assets as shown in the table below, 
which shows the impacted balances from the Group consolidated statement of financial position.

The impact of IFRS 16 on profit after tax as a result of adopting the new standard is not material. However, it has resulted in an increase in operating 
profit due to the operating costs now being replaced with depreciation and interest charges. 

The impact on the cash flow statement has also not been material, although there has been an increase in operating cash flows and decrease in 
financing cash flows, because repayment of the principal portion of the lease liabilities is now classified as cash flows from financing activities rather 
than operating cash flows. 

Ongoing accounting policy
With effect from 1 April 2019, new lease arrangements entered into are recognised as a right-of-use asset and a corresponding liability at the date at 
which the leased asset is available for use by the Group. The right-of-use asset and associated lease liability arising from a lease are initially 
measured at the present value of the lease payments expected over the lease term, plus any other costs. The discount rate applied is the rate implicit 
in the lease or if that is not available, then the incremental rate of borrowing for a similar term and similar security. 

The lease term takes account of exercising any extension options that are at our option if we are reasonably certain to exercise the option and any 
lease termination options unless we are reasonably certain not to exercise the option. 

Each lease payment is allocated between the liability and finance cost. The finance cost is charged to the income statement over the lease period 
using the effective interest rate method. The right-of-use asset is depreciated over the shorter of the asset’s useful life and the lease term on a 
straight-line basis. For short-term leases (lease term of 12 months or less) and leases of low-value assets (such as computers), the Group continues 
to recognise a lease expense on a straight-line basis.

(b) Transition to IFRS 9 and IFRS 15
On 1 April 2018, the Group adopted IFRS 9 and IFRS 15. Both standards were applied using the modified retrospective approach whereby comparative 
amounts were not restated on transition, but a cumulative adjustment was made to retained earnings in the opening consolidated statement of financial 
position as at 1 April 2018. The impact of the transition on the opening consolidated statement of financial position is set out in the following table:

(b) Transition to IFRS 9 and IFRS 15 continued

IFRS 9: Financial Instruments
IFRS 9 has changed the rules concerning the classification and measurement of financial instruments, impairment of financial assets, and hedge 
accounting. Details of the impact of applying IFRS 9 for the year ended 31 March 2019 are set out below.

Adjustments arising in the year ended 31 March 2019 as a result of the transition to IFRS 9: 

1. 

 The available-for-sale category for financial assets was replaced with investments held at fair value through profit and loss (FVTPL) and 
investments held at fair value through other comprehensive income (FVOCI). Changes to the classification and measurement of financial assets 
did not alter the carrying value of any financial assets held by the Group. The net impact to retained earnings of the reclassification on transition 
was an £8 million gain.  

As described in note 15, all recognised financial assets that are within the scope of IFRS 9 are initially recorded at fair value and subsequently 
measured at amortised cost or fair value based on the Group’s business model for managing the financial assets and the contractual cash 
flow characteristics of the financial assets. Therefore on 1 April 2018, the Group reclassified its investments as follows:
•  Money market funds and fund investments held by captive insurance companies were classified as financial assets at FVTPL because their 

contractual cash flows are not solely payments of principal and interest;

•  Investments in debt securities that have contractual payments that are solely payments of principal and interest, and which are held as part 

of the liquidity portfolio or to back employee benefit liabilities, were classified as financial assets at FVOCI because they are held in a 
business model whose objective is to collect the contractual cash flows and to sell the debt instruments;

•  The Group has elected to hold investments in equity securities, which are held to back employee benefit liabilities, as financial assets at 

FVOCI as the Group does not believe that changes in their fair value is reflective of the financial performance of the Group; and

•  Loans to joint ventures and associates, cash at bank, and short-term deposits are classified at amortised cost as they have contractual 

cash flows which are solely payments of principal and interest and the Group holds them to collect contractual cash flows.

Aside from derivative financial instruments, which remain classified as FVTPL, the Group did not previously have any financial assets or liabilities 
classified at FVTPL.

The table below illustrates those financial assets and liabilities that were reclassified at 1 April 2018:

Financial asset/liability

investments in equities and bonds

Cash surrender value of life 
insurance policies and investments 
in debt securities

Note that the table above does not include derivative assets, derivative liabilities, trade receivables, cash at bank and short-term deposits, 
borrowings measured at amortised cost or trade payables. This is because neither the classification nor the measurement of these items has 
changed on transition to IFRS 9. 

2. 

 The change from the incurred loss impairment model of IAS 39 to the expected loss model in IFRS 9 did not have a material impact on the 
Group’s credit loss provision. The Group calculates its impairment provision on trade receivables using a sophisticated provisions matrix. The 
inclusion of forward-looking information did not have a significant impact on the matrix as the relevant short-term future economic conditions 
affecting our retail customers in the US are expected to be similar to recent experience.

3. 

 The Group elected to reclassify an existing liability with a carrying value of £570 million from amortised cost to fair value through profit and loss to 
reduce a measurement mismatch. At transition, the resultant impacts included an increase in the carrying value of the liability of £32 million, a 
reduction in retained earnings of £40 million and the establishment of an own credit reserve (within other equity reserves) of £7 million. 

4.  Deferred tax was recognised on the adjustments recorded on the transition to IFRS 9. Reserve impacts are stated net of related deferred tax. 

5.  Retained earnings included the impact from adjustments 1, 3 and 6. 

6. 

 The Group adopted the hedge accounting requirements of IFRS 9, which more closely align with the Group’s risk management policies. On 
transition, it was concluded that all IAS 39 hedge relationships are qualifying IFRS 9 relationships with the treatment of the cost of hedging being 
the main change. The effect was a reclassification in reserves of a £67 million gain from retained earnings and a £10 million gain from the cash 
flow hedge reserve, into a new cost of hedging reserve (within other equity reserves). In this reserve, qualifying unrealised gains and losses 
excluded from hedging relationships are deferred and released systematically into profit or loss to match the timing of hedged items.

37. Transition to new accounting standards continued
(b) Transition to IFRS 9 and IFRS 15 continued
IFRS 15: Revenue from Contracts with Customers
IFRS 15 has primarily changed the accounting for our connection and diversion revenues in our regulated businesses. No practical expedients on 
transition were applied.

The accounting for revenue under IFRS 15 did not represent a substantive change from the Group’s previous practice under IAS 18 for 
recognising revenue from sales to customers with the exception of the following items:
•  Certain pass-through revenues (principally revenues collected on behalf of the Scottish and Offshore transmission operators) were recorded 
net of operating costs, whereas previously they were recognised gross of operating costs. Had we not adopted IFRS 15, our revenues and 
operating costs for the year ended 31 March 2019 would have been £1,197 million higher, with no impact to operating profits;

•  Contributions for capital works relating to connections for our customers were deferred as contract liabilities on our consolidated statement of 
financial position on transition, and released over the life of the connection assets. This was a change for our US Regulated business and our 
UK Gas Transmission business, where previously revenues were recorded once the work was completed. Had we not adopted IFRS 15, our 
revenues and operating profit for the year ended 31 March 2019 would have been £57 million higher; and

•  In the UK, contributions for capital works relating to diversions were recognised as the works are completed. This was a change for the UK 
regulated businesses where revenues were previously deferred over the life of the asset. Had we not adopted IFRS 15, our revenues and 
operating profit for the year ended 31 March 2019 would have been £26 million and £23 million lower, respectively.

Adjustments arising in the year ended 31 March 2019 as a result of the transition to IFRS 15:

7. 

 Deferred income from contributions for capital works were reclassified to contract liabilities. In addition, these liabilities for capital works relating 
to connections have increased as these capital contributions for connections were cumulatively adjusted for on 1 April 2018 and are now 
deferred and released over the life of the connection assets. This was a change for our US Regulated business and our UK Gas Transmission 
business where previously revenues were recorded once the work was completed. 

Partially offsetting the increase in contract liabilities for connections was the change in accounting treatment for contributions relating to 
diversions in our UK businesses. These contributions are recognised as revenue as the works are completed where previously revenue was 
recognised over the life of the assets.

8. 

 Deferred tax was recorded on the incremental amounts recorded against capital contributions and contract liabilities on the transition to IFRS 15. 
Deferred tax balances have been calculated at the rate substantially enacted at the balance sheet date.

9.  The transition adjustment reflected the net of adjustments 7 and 8 above.

38. Acquisition of Geronimo Energy LLC and Emerald Energy Venture LLC
On 11 July 2019, National Grid Ventures acquired 100% of the share capital of Geronimo Energy LLC (Geronimo) and 51% of Emerald Energy Venture 
LLC (Emerald), which is jointly controlled by National Grid and Washington State Investment Board (WSIB). Geronimo is a leading developer of wind 
and solar generation based in Minneapolis in the US, and the acquisition is a significant step in National Grid’s commitment to the decarbonisation 
agenda, towards developing and growing a large-scale renewable generation business in the US, and delivering sustainable, reliable and efficient 
energy. This is National Grid’s first ownership stake in wind generation and an expansion of our activities in solar generation. Whilst Geronimo 
develops the assets, Emerald has a right of first refusal to buy, build and operate those assets. 

The total consideration was £209 million, satisfied by a combination of cash and contingent consideration. The contingent consideration has been 
recorded within trade and other payables for the amount payable within one year, with the remainder recorded within other non-current liabilities. The 
fair value of contingent consideration recognised is determined as the present value of our best estimate of the value that we will be required to pay, 
taking into consideration management’s estimates of the volume of successful development activity by Geronimo over the relevant period. 

The fair values of the assets and liabilities recognised from both the acquisition of the subsidiary, Geronimo, and the joint venture, Emerald, are set 
out below.

The goodwill arising from the acquisition comprises the value associated with the potential future projects that will be developed by Geronimo as well 
as the expertise of the management team that have been acquired, neither of which qualify for recognition as tangible or intangible assets. At the 
acquisition date, there were no material contingent liabilities. 

Subsequent to the acquisition date, we made an additional capital contribution of £50 million into Emerald. 

Total acquisition-related costs of £3 million have been recognised within operating costs within the consolidated income statement, of which 
£1 million was recognised in the year ended 31 March 2020. 

Geronimo earns revenue from selling its development stage assets to Emerald and other third parties. Emerald generates revenue from the assets it 
purchases from Geronimo once they are operational and has no other business (see note 16). Neither entity has generated significant revenues or 
profits for the period between the acquisition date and the reporting date. Even if the acquisition had completed on 1 April 2019, there would have 
been no significant revenues or profits. 

39. Post balance sheet events
In the period between 31 March 2020 and 17 June 2020, there have continued to be substantial environmental, economic and social changes in 
both the UK and US. As described elsewhere in these Annual Report and Accounts, these have had, and will continue to have, significant 
ramifications for the Group. Other than as disclosed in respect of those areas where forward-looking forecasts are relevant (notably goodwill 
impairment reviews (note 11), expected credit losses on financial instruments including trade receivables (notes 19 and 32) and the presumption of 
the going concern basis generally (note 1)), none of these developments have impacted or caused adjustment to the financial statements.

National Grid plc Annual Report and Accounts 2019/20Financial StatementsCompany accounting policies

Financial Statements 

We are required to include the stand-alone balance sheet of our ultimate Parent Company, National Grid plc, under the Companies Act 2006. 
This is because the publicly traded shares are actually those of National Grid plc (the Company) and the following disclosures provide additional 
information to shareholders.

A. Basis of preparation
National Grid plc is the Parent Company of the National Grid Group, 
which is engaged in the transmission and distribution of electricity and 
gas in Great Britain and northeastern US. The Company is a public 
limited company, limited by shares. The Company is incorporated and 
domiciled in England, with its registered office at 1–3 Strand, London, 
WC2N 5EH.

The financial statements of National Grid plc for the year ended 31 
March 2020 were approved by the Board of Directors on 17 June 2020. 
The Company meets the definition of a qualifying entity under Financial 
Reporting Standard 100 (FRS 100) issued by the Financial Reporting 
Council. Accordingly, these individual financial statements of the 
Company have been prepared in accordance with Financial Reporting 
Standard 101 ‘Reduced Disclosure Framework’ (FRS 101). In preparing 
these financial statements the Company applies the recognition and 
measurement requirements of International Financial Reporting 
Standards (IFRS) as adopted by the EU, but makes amendments where 
necessary in order to comply with the provisions of the Companies Act 
2006 and sets out below where advantage of the FRS 101 disclosure 
exemptions has been taken.

These individual financial statements have been prepared on an 
historical cost basis, except for the revaluation of financial instruments, 
and are presented in pounds sterling, which is the currency of the 
primary economic environment in which the Company operates. The 
2019 comparative financial information has also been prepared on this 
basis.

These individual financial statements have been prepared on a going 
concern basis, which presumes that the Company has adequate 
resources to remain in operation, and that the Directors intend it to do 
so, for at least one year from the date the financial statements are 
signed. As the Company is part of a larger group it participates in the 
Group’s centralised treasury arrangements and so shares banking 
arrangements with its subsidiaries. The Company is expected to 
generate positive cash flows or be in a position to obtain finance via 
intercompany loans to continue to operate for the foreseeable future.

As described further in note 1 to the consolidated financial statements, 
the Directors have considered the impact of COVID-19 on the Group and 
on the Company, and have concluded that the Company will have 
adequate resources to continue in operation for at least 12 months from 
the signing date of these financial statements. Therefore, they continue 
to adopt the going concern basis of accounting in preparing the financial 
statements. 

In accordance with the exemption permitted by section 408 of the 
Companies Act 2006, the Company has not presented its own profit 
and loss account or statement of comprehensive income.

The following exemptions from the requirements of IFRS have been 
applied in the preparation of these financial statements of the 
Company in accordance with FRS 101:
•  a cash flow statement and related notes;
•  disclosures in respect of transactions with wholly owned 

subsidiaries;

•  disclosures in respect of capital management; and
•  the effects of new but not yet effective IFRS standards.

The exemption from disclosing key management personnel 
compensation has not been taken as there are no costs borne by the 
Company in respect of employees, and no related costs are recharged 
to the Company.

As the consolidated financial statements of National Grid plc, which are 
available from the registered office, include the equivalent disclosures, 
the Company has also taken the exemptions under FRS 101 in respect 
of certain disclosures required by IFRS 13 ‘Fair value measurement’ and 
the disclosures required by IFRS 7 ‘Financial instruments: Disclosures’. 

The Company has adopted IFRS 16 with effect from 1 April 2019. The 
adoption of IFRS 16 has had no impact on the Company. 

There are no areas of judgement or key sources of estimation 
uncertainty that are considered to have a significant effect on the 
amounts recognised in the financial statements.

The balance sheet has been prepared in accordance with the 
Company’s accounting policies approved by the Board and described 
below.

B. Fixed asset investments
Investments held as fixed assets are stated at cost less any provisions 
for impairment. Investments are reviewed for impairment if events or 
changes in circumstances indicate that the carrying amount may not be 
recoverable. Impairments are calculated such that the carrying value of 
the fixed asset investment is the lower of its cost or recoverable amount. 
Recoverable amount is the higher of its net realisable value and its 
value-in-use. The Company accounts for common control transactions 
at cost. 

C. Tax
Current tax for the current and prior periods is provided at the amount 
expected to be paid or recovered using the tax rates and tax laws that 
have been enacted or substantively enacted by the balance sheet date.

Deferred tax is provided in full on temporary differences which result in 
an obligation at the balance sheet date to pay more tax, or the right to 
pay less tax, at a future date, at tax rates expected to apply when the 
temporary differences reverse based on tax rates and tax laws that have 
been enacted or substantively enacted by the balance sheet date. 
Deferred tax is provided for using the balance sheet liability method and 
is recognised on temporary differences between the carrying amount of 
assets and liabilities in the financial statements and the corresponding 
tax bases used in the computation of taxable profit.

Deferred tax assets are recognised to the extent that it is regarded as 
more likely than not that they will be recovered. Deferred tax assets and 
liabilities are not discounted.

National Grid plc Annual Report and Accounts 2019/20Company accounting policies continued

D. Foreign currencies
Transactions in currencies other than the functional currency of the 
Company are recorded at the rates of exchange prevailing on the dates 
of the transactions. At each balance sheet date, monetary assets and 
liabilities that are denominated in foreign currencies are retranslated at 
closing exchange rates. Gains and losses arising on retranslation of 
monetary assets and liabilities are included in the profit and loss 
account.

E. Financial instruments
The Company’s accounting policies are the same as the Group’s 
accounting policies under IFRS, namely IAS 32 ‘Financial Instruments: 
Presentation’, IFRS 9 ‘Financial Instruments’ and IFRS 7 ‘Financial 
Instruments: Disclosures’. The Company applies these policies only in 
respect of the financial instruments that it has, namely investments, 
derivative financial instruments, debtors, cash at bank and in hand, 
borrowings and creditors.

The policies are set out in notes 15, 17, 19, 20, 21 and 22 to the 
consolidated financial statements. The Company is taking the exemption 
for financial instruments disclosures, because IFRS 7 disclosures are 
given in notes 32 and 35 to the consolidated financial statements.

F. Hedge accounting
The Company applies the same accounting policy as the Group in 
respect of fair value hedges and cash flow hedges. This policy is set 
out in note 32 to the consolidated financial statements.

G. Parent Company guarantees
The Company has guaranteed the repayment of the principal sum, 
any associated premium and interest on specific loans due by certain 
subsidiary undertakings primarily to third parties. Such guarantees are 
accounted for by the Company as insurance contracts. In the event of 
default or non-performance by the subsidiary, a liability is recorded in 
accordance with IAS 37 with a corresponding increase in the carrying 
value of the investment.

H. Share awards to employees of subsidiary undertakings 
The issuance by the Company to employees of its subsidiaries of 
a grant over the Company’s options represents additional capital 
contributions by the Company to its subsidiaries. An additional 
investment in subsidiaries results in a corresponding increase in 
shareholders’ equity. The additional capital contribution is based 
on the fair value of the option at the date of grant, allocated over the 
underlying grant’s vesting period. Where payments are subsequently 
received from subsidiaries, these are accounted for as a return of a 
capital contribution and credited against the Company’s investments 
in subsidiaries. The Company has no employees.

I. Dividends
Interim dividends are recognised when they are paid to the Company’s 
shareholders. Final dividends are recognised when they are approved 
by shareholders.

J. Directors’ remuneration
Full details of Directors’ remuneration are disclosed on pages 88 to 108.

During the year there was a capital contribution of £19 million (2019: £27 million) which represents the fair value of equity instruments granted to 
subsidiaries’ employees arising from equity-settled employee share schemes. 

Furthermore, the Company made a further investment of £2,000 million in National Grid (US) Holdings Limited, following a rights issue by that 
company; acquired National Grid (US) Investments 2 Limited from an indirect subsidiary undertaking for £2,420 million; and disposed of its 
investments in National Grid Holdings One plc and National Grid (US) Investments 2 Limited in exchange for an investment in National Grid 
Luxembourg Sarl at a cost of £2,572 million.

The Company’s direct subsidiary undertakings as at 31 March 2020 were as follows: National Grid (US) Holdings Limited; NGG Finance plc; and 
National Grid Luxembourg Sarl. The names of indirect subsidiary undertakings, joint ventures and associates are included in note 34 to the 
consolidated financial statements.

The Directors believe that the carrying value of the investments is supported by the fair value of their underlying net assets.

Additional Information | The business in detail

UK regulation
Our licences to participate in transmission and interconnection activities 
are established under the Gas Act 1986 and the Electricity Act 1989, as 
amended (the Acts). These require us to develop, maintain and operate 
economic and efficient networks and to facilitate competition in the 
supply of gas and electricity in Great Britain (GB). They also give us 
statutory powers, including the right to bury our pipes or cables under 
public highways and the ability to use compulsory powers to purchase 
land so we can conduct our business.

will undertake over the year to add value for consumers. Ofgem’s ESO 
Performance Panel will challenge the ESO on its plans, evaluate its 
performance and make recommendations to Ofgem. At the end of the 
year, Ofgem will decide whether to financially reward or penalise the 
ESO up to a maximum cap and floor (where sales revenues above the cap 
are returned to transmission system users, and revenues below the floor 
are topped up by transmission system users, thus reducing the overall 
project risk) of ±£30 million, informed by the Performance Panel’s 
recommendations, as well as other evidence collected throughout the year.

Our licensed activities are regulated by Ofgem, which has a statutory 
duty under the Acts to protect the interests of consumers. To protect 
consumers from the ability of companies to set unduly high prices, 
Ofgem has established price controls that limit the amount of revenue 
such regulated businesses can earn. In setting price controls, Ofgem 
must have regard to the need to secure that licence holders are able to 
finance their obligations under the Acts. Licensees and other affected 
parties can appeal licence modifications which have errors, including in 
respect of financeability. This should give us a level of revenue for the 
duration of the price control that is sufficient to meet our statutory duties 
and licence obligations with a reasonable return on our investments.

The price controls include a number of mechanisms designed to help 
achieve their objectives. These include financial incentives that 
encourage us to:
•  efficiently deliver, through investment and maintenance, the network 
outputs that customers and stakeholders require, including reliable 
supplies, new connections and infrastructure capacity; 

•  innovate so we can continuously improve the services we give 

our customers, stakeholders and communities; and

•  efficiently balance the transmission networks to support the 

wholesale markets. 

The main price controls for electricity and gas transmission networks 
came into effect on 1 April 2013 for the eight-year period until 31 March 
2021. They follow the RIIO (revenue = incentives + innovation + outputs) 
framework established by Ofgem.

Following the sale of a majority interest in the National Grid UK Gas 
Distribution business (now known as Cadent) on 31 March 2017, Cadent 
now has responsibility for operating within the price controls relating to 
its four gas distribution networks. In November 2018, we announced our 
decision to exercise our Options for the sale of our remaining 39% share 
in Cadent and this completed in June 2019. 

Our UK gas and electricity transmission and system operator businesses 
operate under four separate price controls. These comprise two for our 
electricity operations, one covering our role as Transmission Owner (TO) 
and the other for our role as System Operator (SO), and two for our gas 
operations, again one as TO and one as SO. In addition to the four 
regulated network price controls, there is also a tariff cap price control 
applied to certain elements of domestic sized metering activities carried 
out by National Grid Metering and also regulation of our electricity 
interconnector interests.

In 2017 Ofgem, the Department for Business, Energy and Industrial Strategy 
(BEIS) and National Grid plc agreed to create a legally separate business,  
the Electricity System Operator (ESO), within the National Grid Group. The 
ESO became a separate entity within the Group on 1 April 2019.

A primary goal of ESO legal separation in April 2019 was to increase 
transparency of our activities and help minimise any perceived conflicts 
of interest as we take on the challenge of driving forward the energy 
transformation. There are clear signals from Ofgem and the broader 
regulatory context that the ESO will play a crucial role in the changing 
energy environment. As an asset-light and service-based entity the ESO 
is also fundamentally different from other regulated network companies. 
The new price control arrangements for RIIO-2 are therefore an opportunity 
to implement a new regulatory framework that enables us to meet our 
stakeholders’ expectations.

In April 2018, Ofgem introduced a new regulatory and incentives 
framework for the ESO. This moved away from the use of targeted, 
mechanistic incentives towards a ‘principles-based’ evaluative incentives 
approach. The new approach includes a set of ‘Roles and Principles’ 
designed to set clear expectations about the baseline behaviours we 
expect from the ESO and a requirement for the ESO to produce a Forward 
Plan, following stakeholder engagement, demonstrating the activities it 

In 2019, the ESO published a mission and set of ambitious goals 
accompanied by its Forward Plan and its RIIO-2 business plan to set out 
what, when and how it delivers. This RIIO-2 business plan reflects the 
ambition shared by us and Ofgem for the ESO to be innovative, 
ambitious and agile, responding to stakeholder needs and the changing 
energy landscape.

Ofgem published terms of reference for a review of system operators 
on 13 February 2020. The aim of the review is to consider the current 
and future challenges facing GB System Operation and assess whether 
the right governance framework is in place to deliver the UK’s net zero 
emissions target at lowest cost to consumers. A report on the outcome 
of the review will be produced which is expected to be received in June 
2020 or later.

Interconnectors derive their revenues from sales of capacity to users 
who wish to move power between market areas with different prices. 
Under European legislation, these capacity sales are classified as 
‘congestion revenues’. This is because the market price differences 
result from congestion on the established interconnector capacity which 
limits full price convergence. European legislation governs how congestion 
revenues may be used and how interconnection capacity is allocated. 
It requires all interconnection capacity to be allocated to the market through 
auctions. Under UK legislation, interconnection businesses must be 
separate from transmission businesses. 

There is a range of different regulatory models available for 
interconnector projects. These involve various levels of regulatory 
intervention, ranging from fully merchant (where the project is fully reliant 
on sales of interconnector capacity) to cap and floor.

The cap and floor regime is now the regulated route for interconnector 
investment in GB and may be sought by project developers who do 
not qualify for, or do not wish to apply for, exemptions from European 
legislation which would facilitate a merchant development. 

RIIO price controls 
The building blocks of the RIIO price control are broadly similar to 
the price controls historically used in the UK. There are, however, 
some significant differences in the mechanics of the calculations. 

How is revenue calculated? 
Under RIIO, the outputs we deliver are explicitly articulated and our 
allowed revenues are linked to their delivery. These outputs were 
determined through an extensive consultation process, which gave 
stakeholders a greater opportunity to influence the decisions. 

There are five output categories for transmission under the current 
RIIO price controls:

Safety: ensuring the provision of a safe energy network. 

Reliability (and availability): promoting networks capable of delivering 
long-term reliability, minimising the number and duration of interruptions 
experienced during the price control period and ensuring adaptation to 
climate change. 

Environmental impact: encouraging companies to play their role 
in achieving broader environmental objectives, specifically, facilitating 
the reduction of carbon emissions, as well as minimising their own 
carbon footprint. 

Customer and stakeholder satisfaction: maintaining high levels of 
customer satisfaction and stakeholder engagement, and improving 
service levels. 

Customer connections: encouraging networks to connect customers 
quickly and efficiently.

The business in detail continued

Within each of these output categories are a number of primary and 
secondary deliverables that reflect what our stakeholders want us to 
deliver over the remaining price control period and in preparation for 
future periods. The nature and number of these deliverables vary 
according to the output category. Some are linked directly to our 
allowed revenue and some to legislation, while others have only a 
reputational impact. 

Using information we have submitted, along with independent 
assessments, Ofgem determines the efficient level of expected costs 
necessary for these deliverables to be achieved. Under RIIO this is 
known as ‘totex’, which is a component of total allowable expenditure 
and is broadly the sum of what was defined in previous price controls 
as operating expenditure (opex) and capital expenditure (capex).

A number of assumptions are necessary in setting allowances for these 
outputs, including the volumes of work that will be needed and the price 
of the various external inputs required to achieve them. Consequently, 
there are a number of uncertainty mechanisms within the RIIO framework 
that can result in adjustments to totex allowances if actual input prices or 
work volumes differ from the assumptions. 

Where we under- or over-spend the allowed totex for reasons that are 
not covered by uncertainty mechanisms, there is a ‘sharing’ factor. This 
means we share the under- or over-spend with customers through an 
adjustment to allowed revenues in future years. This sharing factor provides 
an incentive for us to provide the outputs efficiently, as we are able to keep 
a portion of savings we make, with the remainder benefiting our customers.

The extended eight-year length of the first round of RIIO price controls 
is one of the ways that RIIO has given innovation more prominence. 
Innovation refers to all the new ways of working that deliver outputs more 
efficiently. This broad challenge has an impact on everyone in our business.

Allowed revenue to fund totex costs is split between RIIO ‘fast’ and ‘slow’ 
money categories using specified ratios that are fixed for the duration of 
the price control. Fast money represents the amount of totex we are able 
to recover in the year of expenditure. Slow money is added to our 
Regulatory Asset Value (RAV) – effectively the regulatory IOU. (For more 
details on the sharing factors under RIIO, please see the table overleaf).

In addition to fast money, each year we are allowed to recover regulatory 
depreciation, i.e. a portion of the RAV and a return on the outstanding 
RAV balance. Regulatory depreciation in electricity and gas transmission 
permits recovery of RAV consistent with each addition bringing benefit to 
consumers for a period of up to 45 years. We are also allowed to collect 
additional revenues related to non-controllable costs and incentives. 
In addition to totex sharing, RIIO incentive mechanisms can increase or 
decrease our allowed revenue to reflect our performance against various 
other measures related to our outputs. For example, performance 
against our customer and stakeholder satisfaction targets can have 
a positive or negative effect of up to 1% of allowed annual revenues. 
Many of our incentives affect our revenues two years after the year 
of performance.

During the eight-year period of the RIIO-T1 price control, our regulator 
included a provision for a mid-period review, which was completed 
during 2017 and led to some changes in allowances relating to certain 
specific costs. Further to the mid-period review, National Grid volunteered 
that £480 million (in 2009/10 prices) of allowances for electricity 
transmission investments should be deferred. In August 2017, Ofgem 
determined how the RIIO allowances would be correspondingly adjusted. 

Competition in onshore transmission
Ofgem stated in its final decision on the RIIO-T1 price control for 
electricity transmission that it would consider holding a competition to 
appoint the constructor and owner of suitably large new transmission 
projects, rather than including these new outputs and allowances in 
existing transmission licensee price controls. In the absence of the 
legislation needed to support a competition, at the end of July 2018, 
and after consultation, Ofgem decided to fund the delivery of the 
Hinkley-Seabank (HSB) electricity transmission project by National Grid 
through a regulatory model called the ‘Competition Proxy Model’ (CPM). 
This regulatory model seeks to replicate the outcome of an efficient 
competitive process for the financing, construction and operation of the 
project and to provide National Grid Electricity Transmission with a 
project-specific revenue allowance over the period of its construction 
and 25 years of operation, but with reduced allowances reflecting prices 
that Ofgem has observed in other competitions. Ofgem subsequently 
updated the analysis which supported this decision, and in October 2019 
consulted on a new minded-to position to fund delivery of the HSB project 
through the Strategic Wider Works (SWW) mechanism under the RIIO 
price control framework, rather than through the CPM as previously intended. 
The CPM is intended to be a ‘late competition’ model.

The ESO, at Ofgem’s request, is developing an Early Competition Plan. 
This plan will set out how a model for Early Competition could be 
implemented, identifying the process, roles and responsibilities, code 
and licence changes required along with cost and timescales to 
implement. Plans are being co-created with stakeholders to ensure 
developed model(s) are attractive to potential bidders in addition to being 
achievable and aligned with network planning processes. As part of this 
work, the ESO is also considering what, if any, role the ESO could have 
in distribution level competition. The Early Competition Plan is due to be 
completed by the end of February 2021.

In addition, the RIIO-T1 price controls for transmission included a

time of setting allowances. Both our gas and electricity transmission 
businesses requested additional funding under this mechanism in 
May 2018, leading to some changes to the allowed revenues.

Sharing factors are used to share over- and under-spends of allowed 
totex between the businesses and customers. The sharing figures 
displayed in the table below are the sharing factors that apply to our 
electricity and gas transmission businesses, for both TO and SO.

1.   Fast money allows network companies to recover a percentage of totex within a 

one-year period. 

2.   Slow money is where costs are added to RAV and, therefore, revenues are recovered 

slowly (e.g. over 45 years) from both current and future customers.

3.   The baseline is the expenditure that is funded through ex-ante allowances, whereas 
the uncertainty adjusts the allowed expenditure where the level of outputs delivered 
differ from the baseline level, or if triggered by an event.

RIIO-2
Ofgem has started work on the next round of RIIO price controls (RIIO-2) 
for the energy network sectors it regulates, including both gas and 
electricity transmission. It has consulted on a wide range of topics, 
including incentives, outputs, the cost of capital and other financial 
parameters. Decisions that have already been taken include reducing 
the default price control duration back to five years from eight years, 
extending the role of competition where appropriate from electricity 
transmission to other sectors and moving away from RPI to CPIH for 
inflation measurement when calculating RAV and allowed returns. In 
addition, Ofgem has proposed a methodology for the baseline-allowed 
cost of equity which, based on the evidence available, it used in May 
2019 to calculate its working assumption for RIIO-2 that is lower than 
the value under the current RIIO price controls. The RIIO-2 proposals 
will also apply, in part, to the ESO, but due to the nature of its activities 
some elements are less applicable to the ESO, and Ofgem has proposed 
that the duration will remain as a five-year price control, but with business 
plans (and totex allowances) it will be on a two-year cycle and overall the 
financial framework for the ESO is likely to be very different. 

We and other stakeholders will continue to work with Ofgem to develop 
the framework and parameters for RIIO-2. We submitted business plans 
in December 2019 and Ofgem is expected to publish and consult on its 
draft determination in summer 2020, followed by the final price control 
determination for transmission companies before the end of 2020.

US regulation
Regulators 
In the US, public utilities’ retail transactions are regulated by state utility 
commissions. The commissions serve as economic regulators, 
approving cost recovery and authorised rates of return. The state 
commissions establish the retail rates to recover the cost of transmission 
and distribution services, and focus on services and costs within their 
jurisdictions. They also serve the public interest by making sure utilities 
provide safe and reliable services at just and reasonable prices. The 
commissions establish service standards and approve public utility 
mergers and acquisitions.

The Federal Energy Regulatory Commission (FERC) regulates wholesale 
transactions for utilities, such as interstate transmission and wholesale 
electricity sales, including rates for these services, at the federal level. 
FERC also regulates public utility holding companies and centralised 
service companies, including those of our US businesses.

Regulatory process 
The US regulatory regime is premised on allowing the utility the 
opportunity to recover its cost of service and earn a reasonable return on 
its investments as determined by the commission. Utilities submit formal 
rate filings (rate cases) to the relevant state regulator when additional 
revenues are necessary to provide safe, reliable service to customers. 
Utilities can be compelled to file a rate case, either due to complaints 
filed with the commission or at the commission’s own discretion.

The rate case is typically litigated with parties representing customers 
and other interests. In the states where we operate, it can take 9 to 
13 months for the commission to render a final decision. The utility is 
required to prove that the requested rate change is prudent and 
reasonable, and the requested rate plan can span multiple years. Unlike 
the state processes, the federal regulator has no specified timeline for 
adjudicating a rate case; typically it makes a final decision retroactive 
when the case is completed.

Gas and electricity rates are established from a revenue requirement, 
or cost of service, equal to the utility’s total cost of providing distribution 
or delivery service to its customers, as approved by the commission in 
the rate case. This revenue requirement includes operating expenses, 
depreciation, taxes and a fair and reasonable return on shareholder 
capital invested in certain components of the utility’s regulated asset 
base. This is typically referred to as its rate base.

The final revenue requirement and rates for service are approved in 
the rate case decision. The revenue requirement is derived from a 
comprehensive study of the utility’s total costs during a recent 12-month 
period of operations, referred to as a test year. Each commission has its 
own rules and standards for adjustments to the test year. These may 
include forecast capital investments and operating costs.

Our rate plans
Each operating company has a set of rates for service. We have three 
electric distribution operations (upstate New York, Massachusetts and 
Rhode Island) and six gas distribution networks (upstate New York, 
New York City, Long Island, Massachusetts (two) and Rhode Island).

Our distribution operating companies have revenue decoupling 
mechanisms that delink their revenues from the quantity of energy 
delivered and billed to customers. These mechanisms remove the 
natural disincentive utility companies have for promoting and 
encouraging customer participation in energy-efficiency programmes 
that lower energy end use and distribution volumes.

Additional Information

The business in detail continued

We bill our customers for their use of electricity and gas services. 
Customer bills typically cover the cost of electricity or gas delivered, and 
charges covering our delivery service. With the exception of residential 
gas customers in Rhode Island, our customers are allowed to select an 
unregulated competitive supplier for the commodity component of 
electricity and gas utility services. 

A substantial proportion of our costs, in particular electricity and gas 
commodity purchases, are ‘pass-through’ costs. This means they are 
fully recoverable from our customers. We recover ‘pass-through’ costs 
through making separate charges to customers, designed to recover 
those costs with no profit. We adjust rates from time to time to make 
sure that any over- or under-recovery of these costs is returned to, or 
recovered from, our customers.

Our rate plans are designed to a specific allowed Return on Equity (RoE), 
by reference to an allowed operating expense level and rate base. Some 
rate plans include earnings-sharing mechanisms that allow us to retain 
a proportion of the earnings above our allowed RoE, achieved through 
improving efficiency, with the balance benefiting customers.

In addition, our performance under certain rate plans is subject to 
service performance targets. We may be subject to monetary penalties 
in cases where we do not meet those targets.

Our FERC-regulated transmission companies use formula rates (instead 
of periodic stated rate cases) to set rates annually that recover their cost 
of service. Through the use of annual true-ups, formula rates recover our 
actual costs incurred and the allowed RoE based on the actual transmission 
rate base each year. We must make annual formula rate filings documenting 
the revenue requirement that customers can review and challenge.

Revenue for our wholesale transmission businesses in New England 
and New York is collected from wholesale transmission customers. 
These are typically other utilities and include our own New England 
electricity distribution businesses. With the exception of upstate 
New York, which continues to combine retail transmission and 
distribution rates to end-use customers, these wholesale transmission 
costs are incurred by distribution utilities on behalf of their customers. 
They are fully recovered as a pass-through from end-use customers, 
as approved by each state commission.

Our Long Island generation plants sell capacity to the Long Island Power 
Authority (LIPA) under 15-year and 25-year power supply agreements 
and within wholesale tariffs approved by FERC. Through the use of 
cost-based formula rates, these long-term contracts provide a similar 
economic effect to cost-of-service rate regulation.

One measure used to monitor the performance of our regulated 
businesses is a comparison of achieved RoE to allowed RoE. However, 
this measure cannot be used in isolation, as several factors may prevent 
us from achieving the allowed RoE. These include financial market 
conditions, regulatory lag and decisions by the regulator preventing 
cost recovery in rates from customers.

We work to increase achieved RoE through: 
•  productivity improvements; 
•  positive performance against incentives or earned savings 

mechanisms, such as available energy-efficiency programmes; and 
•  filing a new rate case when achieved returns are lower than those the 
Company could reasonably expect to attain through a new rate case.

US regulatory filings 
The objectives of our rate case filings are to make sure we have the right 
cost of service and are able to earn a fair and reasonable rate of return, 
while providing safe, reliable and economical service. To achieve these 
objectives and reduce regulatory lag, we have been requesting structural 
changes, such as: 
•  revenue decoupling mechanisms; 
•  capital trackers; 
•  commodity-related bad debt true-ups; 
•  pension and other post-employment benefit true-ups, separately from 

base rates; and

•  performance-based frameworks such as incentives and multi-year plans.

We explain these terms below in the table on page 226.

Below, we summarise significant, recent developments in rate filings 
and the regulatory environment. In 2017/18, we made full rate case 
filings with Niagara Mohawk (electric and gas), in April 2017; Boston Gas 
and Colonial Gas, in November 2017; and the Narragansett Electric 
Company, also in November 2017. A joint proposal, setting forth a 
three-year rate plan for Niagara Mohawk, was approved by the New 
York State Public Service Commission (NYPSC) in March 2018. An 
amended settlement agreement setting forth a three-year rate plan 
for the Narragansett Electric Company was approved by the Rhode 
Island Public Utilities Commission (RIPUC) in August 2018. An order, 
establishing new base rates for Boston Gas and Colonial Gas, was 
approved by the Massachusetts Department of Public Utilities (MADPU) 
in September 2018. In 2018/19, we made a full rate case filing for 
Massachusetts Electric in November 2018. In 2019/20, we made a full 
rate case filing for KEDNY and KEDLI in April 2019. More recently, an 
order, setting forth a five-year performance-based ratemaking plan, was 
approved by MADPU in September 2019. These filings are expected to 
capture the benefit of recent increased investments in asset replacement 
and network reliability, and reflect long-term growth in costs, including 
property tax and healthcare costs. 

Massachusetts 
Massachusetts Electric and Nantucket Electric rate cases
We filed a rate case for Massachusetts Electric and Nantucket Electric 
with MADPU on 15 November 2018 with new rates effective on 
1 October 2019. The Massachusetts Electric rate case is the first for 
Massachusetts Electric and Nantucket Electric since the case filed in 
2015. It updates the electric companies’ rates to more closely align 
revenues with the cost of service and bring their earned RoEs closer to 
the allowed RoE. New rates were approved with an allowed RoE of 9.6% 
on an equity ratio of 53.5%. MADPU approved a five-year performance-
based ratemaking plan, which adjusts distribution rates annually based 
on a predetermined formula. As part of its decision, MADPU is requiring 
a management audit addressing the Company’s strategic planning 
processes, staffing decisions and its relationship to National Grid USA 
Service Company. The audit will take place in two phases beginning in 
mid-2020 and ending with a final report in 2021. The Company cannot 
predict the outcome of this proceeding.

Merger of Boston Gas Company and Colonial Gas Company
On 16 December 2019, MADPU approved the Company’s proposal to 
legally merge Colonial Gas Company into Boston Gas Company. The 
two companies had already effectively consolidated their operations, but 
the legal merger of these two entities allows for certain small efficiencies 
and cost savings. The legal merger was effective as of 15 March 2020. 
However, for ratemaking purposes, the Company must still maintain 
separate rates for customers of legacy Boston Gas Company and legacy 
Colonial Gas Company, until otherwise approved by MADPU.

Electric vehicle programmes
In September 2018, MADPU approved with modifications a petition filed 
by Massachusetts Electric Company and Nantucket Electric Company 
for approval of a three-year pilot Electric Vehicle Market Development 
Programme (EV Programme). The total allowed cost, including a 
performance incentive, is approximately $20 million. The companies 
submitted their first cost recovery filing in May 2020 with effect from 
1 July 2020. 

In September 2019 MADPU issued its final order in the Petition of 
Massachusetts Electric Company and Nantucket Electric Company for 
Approval of General Increases in Base Distribution Rates for Electric 
Service, which included approval of limited components of the 
companies’ proposed five-year Phase II Electric Vehicle Programme 
(Phase II). The total allowed cost for Phase II is approximately $9 million. 

MADPU allowed the companies to file future EV proposals under the 
umbrella of the grid modification proceedings, which the companies 
plan to do. Cost recovery for both the EV Programme and Phase II is 
governed by the Electric Vehicle Programme Provision.

Solar Massachusetts Renewable Target Program
In September 2018, MADPU approved a petition jointly filed by the 
Massachusetts electric distribution companies, including Massachusetts 
Electric Company and Nantucket Electric Company, to offer their 
customers a new solar programme. Following state legislation enacted in 
2016, the Solar Massachusetts Renewable Target (SMART) Programme 
is required by state regulations issued by the Department of Energy 
Resources (DOER). The programme’s objective is to develop a further 
1,600 MW of customer-based solar power, at a lower cost than the prior 
two solar programmes. It aims to do this by providing on-bill credits and 
incentive payments, directly from the Company to the customer, at a 
lower cost than previous programmes. Massachusetts Electric 
Company’s SMART allocation for large solar projects was filled up 
shortly after SMART opened. In November 2019, the Company has 
completed its first full year of enrolling projects in SMART and has 
submitted its proposed 2020 SMART Factor to recover its costs, 
which MADPU has approved subject to further review and investigation. 
In April 2020, DOER issued emergency regulations for additional SMART 
capacity, for review and comment. The SMART regulations require an 
additional 1,600 MW of customer-based solar power, and DOER has 
proposed certain changes to the programme incentive structure. About 
half of the total capacity will be located within the service territories of 
Massachusetts Electric Company and Nantucket Electric Company, 
as with the initial SMART programme. The regulations are effective 
immediately. In May 2020, DOER conducted a virtual public hearing 
and accepted written comments. Once DOER adopts final regulations, 
the electric distribution companies must file amended tariffs to allow 
for the expansion of SMART in summer/autumn 2020.

Statewide assessment of gas pipeline safety 
In November 2018, MADPU initiated an independent statewide pipeline 
safety audit of the natural gas distribution systems in Massachusetts and 
hired an independent auditor. The auditor assessed the safety of the gas 
systems in the entire state and made recommendations for improvements 
that may impact operations of Boston and Colonial Gas and pipeline 
safety compliance requirements in the future. The auditor’s final report 
was issued 29 January 2020, and included 37 recommendations for all 
the gas companies in Massachusetts as well as state agencies and 
other stakeholders. The final report also included a number of opportunities 
specific to Boston Gas and Colonial Gas. MADPU directed the gas 
companies to file plans in response to the final report. Boston Gas 
and Colonial Gas filed their plan on 28 February 2020, in which they 
accepted the final report’s recommendations and opportunities, and 
detailed their actions to assess and address the recommendations and 
observations. MADPU may take further action on the auditor’s final 
report, but the Company cannot predict what that action may be. 

Gas System Enhancement Plan (GSEP)
On 30 April 2019, MADPU approved our recovery of approximately 
$49.5 million in revenue requirements, related to $269.2 million of 
anticipated investments in 2019 under an accelerated pipe replacement 
programme, through rates effective from May 2019 to April 2020. 
MADPU also raised the cap on GSEP recoveries from 1.5% of revenue 
to 3% of revenue. 

Grid modernisation
In response to a 2014 regulatory requirement, we filed a Massachusetts 
electricity grid modernisation plan on 19 August 2015 that proposed 
multiple investment options. An order from MADPU approving some 
of the proposed investment was received on 10 May 2018. In its order, 
MADPU refined their objectives for grid modernisation to be: optimise 
system performance; optimise system demand and interconnect; and 
integrate distributed energy resources. We continue to implement our 
grid modernisation plan, and will be making annual cost recovery and 
annual update filings in conjunction with the plan in March and April of 
each year, respectively. We will also file our next proposed three-year 
grid modernisation plan (for 2021–23) on 1 July 2020. 

Massachusetts large-scale renewable contracts/clean 
energy contracts
During 2018, pursuant to state legislation enacted in 2016, our 
Massachusetts electric distribution companies, Massachusetts Electric 
Company and Nantucket Electric Company, filed with MADPU requests 
for approval of long-term contracts for their pro rata share of output and 
associated transmission from hydroelectric generation from Canada 
(approximately 1,200 MW), and from an offshore wind energy generation 
project (approximately 800 MW) to be located on the outer continental shelf.

Between April and June 2019, MADPU approved all of these 
contracts, along with the companies’ request to recover the costs 
and remuneration equal to 2.75% of the annual payments under the 
contracts. The MADPU approval of the contracts for hydroelectric 
generation from Canada was appealed to the Massachusetts Supreme 
Judicial Court in July 2019. Despite COVID-19, the parties have been 
heard, but the court has no specific deadline to issue a decision, and 
the contracts will not become effective without a decision from the 
court affirming final regulatory approval.

Also, the 2016 legislation requires the companies to solicit a total of 
1,600 MW of offshore wind energy generation, and a second competitive 
solicitation was issued in March 2019. In February 2020, Massachusetts 
Electric Company and Nantucket Electric Company submitted long-term 
contracts for their pro rata share of offshore wind energy generation 
(approximately 804 MW) to MADPU, seeking regulatory approval of the 
contracts, along with a request to recover the costs and remuneration 
equal to 2.75% of the annual payments under the contracts. While 
MADPU has no specific deadline to approve the contracts, despite 
COVID-19, hearings have been scheduled for July 2020.

The contracts will not become effective without regulatory approval.

New York 
Downstate New York 2019 rate cases
KEDNY and KEDLI filed a rate case with the NYPSC on 30 April 2019 
seeking to increase delivery revenues by $195 million and $61 million, 
respectively, for the year ending 31 March 2021. The filings propose 
more than $1.5 billion in capital investments to modernise KEDNY and 
KEDLI’s gas infrastructure by replacing ageing pipelines, implementing 
safety improvements, enhancing storm hardening and resiliency, and 
reducing methane emissions. The filings also include proposals to 
enhance gas safety and promote a sustainable and affordable path 
towards a low-carbon energy future. We are resuming settlement 
negotiations in the interest of agreeing on a multi-year rate plan that 
mitigates bill impacts for our customers while allowing us to maintain 
safe and reliable service, advance our clean energy goals, and earn a 
reasonable return. If we are unable to reach a negotiated settlement, the 
rate cases will continue to a litigated outcome at which time we would 
then plan to file a new multi-year rate case proposal. 

We also agreed to develop a range of options to address the natural gas 
constraints facing the region, which were initially presented in a report 
on 24 February 2020 outlining the gas capacity constraints affecting 
the downstate New York service territory and the reasonably available 
options for meeting long-term customer demand. These options were 
further presented at a series of six public meetings during March 2020 
in the downstate New York service territory. These meetings were 
designed to facilitate a dialogue with customers, residents, advocates, 
business leaders and local elected officials on potential solutions. On 
8 May 2020, we published a supplemental report with refined forecasts 
and additional analyses to evaluate the options for addressing the 
downstate New York supply constraints, including a preliminary 
assessment of the impacts of COVID-19 on customer demand, as well 
as a summary of the public’s comments and feedback on the potential 
solutions. In mid-May certain permits were denied in New York and New 
Jersey for a pipeline solution and therefore we are advancing a portfolio 
of solutions that were identified in the supplementary report. 

In light of the financial hardships our customers have experienced from 
COVID-19, we delayed implementation of certain previously approved 
rate increases. We also delayed filing a rate case this Spring and are 
exploring options including an extension of the current rate plan or a rate 
case filing later this Summer.

New York regulatory audits
Under the New York Public Service Law, the NYPSC is required to 
conduct periodic audits of various aspects of public utility activities. In 
2018 the NYPSC initiated a comprehensive management and operations 
audit of our three New York regulated businesses. New York law requires 
periodic management audits of all utilities at least once every five years. 

National Grid’s New York regulated business last underwent a New York 
management audit in 2014, when the NYPSC audited our New York 
gas business. 

In September 2018, the NYPSC selected Saleeby Consulting Group as 
the independent auditor to perform the audit. The Company was fully 
committed to the audit with the goal of demonstrating its full capabilities 
and receiving meaningful feedback that would drive useful recommendations 
to improve the Company’s electric and gas operations for the benefit of 
its customers. The audit began in November 2018 and ran until August 
2019, with a final report due in September 2019. Unexpectedly, in 
October 2019, the NYPSC employees advised us that they were 
terminating the contract with the auditors, effective immediately, because 
of the poor quality of the draft audit report by the auditor, with no fault 
whatsoever on the part of the Company. NYPSC employees advised 
their intention to complete the management audit themselves. The audit 
is expected to be completed sometime in the second half of 2020.

Downstate gas settlement
In May 2019, KEDNY and KEDLI stopped fulfilling applications for new 
and expanded firm service in most of their downstate New York service 
territories because the available firm gas supplies were insufficient to keep 
pace with demand. On 11 October 2019, the NYPSC issued an ‘Order 
Instituting Proceeding and to Show Cause’ that directed the Companies 
to provide gas service to a subset of previously denied applicants and 
show cause why the Companies should not be subject to financial 
penalties. On 24 November 2019, the Companies reached a settlement 
that was approved on 26 November 2019 by the NYPSC. The 
agreement resolves the proceeding opened by the NYPSC relating to 
the moratorium and provides the necessary framework for resolving the 
longer-term energy supply issues. Specifically, the settlement provides 
that KEDNY and KEDLI will lift the moratorium for approximately two 
years. National Grid will offer $7 million in customer assistance to 
address hardships resulting from the moratorium. National Grid also 
agreed to fund $8 million for new energy-efficiency and gas-conservation 
measures designed to relieve stress on the system and reduce peak-day 
gas usage, as well as $20 million of clean technology investments and 
programmes in New York. The settlement provides for the appointment 
of a monitor to oversee our downstate New York gas supply operations 
and compliance with the settlement. 

Advanced Metering Infrastructure
On 15 November 2018, Niagara Mohawk Power Corporation (NMPC) 
filed a report with the NYPSC detailing the initial outcome of NMPC’s 
Advanced Metering Infrastructure (AMI) research and collaborative 
sessions. The report, which included an AMI Business Plan, a detailed 
benefit-cost analysis, and a Customer Engagement Plan, proposed a 
six-year deployment of electric AMI meters and AMI-compatible gas 
modules in NMPC’s service territory beginning in 2019/20. This 
investment would modernise both customer and grid-facing components 
of the Company’s distribution system and is considered a key enabler 
of NMPC’s strategy to address the comprehensive state energy goals 
expressed in New York’s Reforming the Energy Vision proceedings. 
The near-term benefits include greater customer choice and control over 
energy use; improved system modelling, load forecasting, and capital 
investment planning; increased system efficiency; and operational 
efficiencies for outage response. On 4 September 2019, we filed a 
supplemental report detailing the AMI collaborative’s continued work. 
The filing provided an updated benefit-cost analysis and proposed a 
six-year, $640 million (20-year NPV) deployment of electric AMI meters 
and AMI-compatible gas modules in NMPC’s service territory beginning 
in 2019/20. Our proposal to deploy AMI is currently pending before the 
NYPSC. If approved by the NYPSC, the Company would replace 
approximately 1.7 million electric and 640,000 gas metering points.

Rhode Island 
Rhode Island combined gas and electric rate case
On 24 August 2018, the Rhode Island Public Utilities Commission 
(RIPUC) approved the terms of an Amended Settlement Agreement 
(ASA). We are currently in year two of the Company’s multi-year rate 
plan. The rate plan includes a 9.275% RoE on an equity ratio of 51%.  
The ASA also requires the Company to file the next rate case so that 
new rates take effect no later than 1 September 2022, unless the RIPUC 
consents to an extension of the term and specifies another date upon 
which rates are to take effect. The Company will file its Rate Year 3 
compliance filing on 1 June 2020 for distribution rates for year three 
of the multi-year rate plan, effective 1 September 2020.

Rhode Island Aquidneck Island gas service interruption
On 21 January 2019, we suffered a significant loss of gas supply to the 
distribution system that serves our customers on Aquidneck Island in 
Rhode Island. As a result, we made the decision to interrupt the gas 
service to the Aquidneck Island system to protect the safety of our 
customers and the public. Overall, approximately 7,500 customers lost 
their gas service. On 30 October 2019, RIPUC issued an Investigation 
Report regarding the gas service interruption which identified the causes 
of the outages, which included multiple factors, some of which were 
outside the control of the Narragansett Electric Company. RIPUC’s 
Report also recommended several gas system improvements, many of 
which we have addressed already. On 13 December 2019, we filed our 
response to the RIPUC’s Report and continue to meet with RIPUC on 
a quarterly basis regarding winter reliability issues for Aquidneck Island 
and Rhode Island.

Power Sector Transformation/Advanced Metering Functionality
On 27 November 2017, we filed a Power Sector Transformation (PST) 
Vision and Implementation Plan in conjunction with our combined gas 
and electric rate case (the PST Plan). The PST Plan proposed a suite 
of investments, including the full deployment of Advanced Metering 
Functionality (AMF), which were designed to modernise the state’s 
energy infrastructure. We intend to file our Updated AMF Business Case 
and Grid Modernisation Plan (GMP) with the RIPUC in the second half of 
2020/21. The Updated AMF Business Case will present a detailed plan 
for full-scale AMF deployment in Rhode Island, using a Rhode Island-
only scenario and a combination Rhode Island and New York 
deployment scenario to demonstrate the cost synergies that can be 
achieved through a multi-jurisdictional deployment. The estimated cost 
of the Rhode Island programme is approximately $414 million over 20 
years in nominal terms (assuming a Rhode Island-only deployment), 
which reflects the estimated useful life of the meters. The GMP will 
present a ten-year road map to guide the future development of projects 
and programmes to enhance distribution system planning and 
operations, which will be separately recovered as part of the 
Infrastructure, Safety and Reliability Plan or a future rate case.

Heating Sector Transformation
On 8 July 2019, the Governor signed Executive Order 19-06 launching 
the Heating Sector Transformation (HST) Initiative to advance the state’s 
development of clean, affordable, and reliable heating technologies. Two 
state agencies, the Office of Energy Resources (OER) and the Division of 
Public Utilities and Carriers (Division), were tasked to lead the initiative 
and instructed to work with government and non-government partners 
in the development of a report. We engaged with OER, the Division, 
and external stakeholders through a series of facilitated workshops. 
On 22 April 2020, the recommendations were provided to the Governor 
concluding that no one solution was more economically attractive than 
any other, and the state’s decarbonisation solutions should include 
increased energy efficiency, decarbonised electrification through air and 
ground source heat pumps, and fuel decarbonisation through renewable 
natural gas and renewable oil. The document presented guiding 
principles, rather than technology mandates, for additional policy 
development proffering that the heating sector policy should remain 
technology-agnostic while promoting early demonstration and 
development of promising, carbon-reducing technologies. The report 
does not specify next steps; however, OER acknowledged it will be 
conducting an energy and economic analysis to inform actional 
pathways to meet the Governor’s January 2020 Executive Order goal of 
meeting the state’s electricity demand with 100% renewable resources 
by 2030, which will be linked to decarbonising the heating sector.

Infrastructure, Safety and Reliability Plans
We filed our 2021 Gas and Electric Infrastructure, Safety and Reliability 
(ISR) Plans on 20 December 2019 for effect 1 April 2020. The Electric 
ISR Plan proposes capital spending of $103.8 million, plus $10.4 million 
for vegetation management and total operation and maintenance expense 
of $1.8 million. The Gas ISR Plan proposes total capital spending of 
$198.6 million. On 17 March 2020, RIPUC approved the Company’s Gas 
and Electric ISR Plans, which include $200 million and $104 million of 
investments, respectively, for 2020/21. The Electric ISR Plan investment 
also includes $3.7 million to readily respond to distributed energy 
resource (DER) interconnections and $12 million of operation and 
maintenance expense for vegetation management and inspection and 
maintenance programmes. RIPUC slightly modified the Electric ISR Plan 
to move $2 million for certain strategic DER investments such as 
advance capacitors and feeder monitor systems from the discretionary 
category (system capacity and performance) to the non-discretionary 
category. This means that the Company is allowed to invest in those 
assets if required by the system needs or customer connections, but we 
may defer the proactive investment in those technologies until after the 
Grid Modernisation plan is approved. The RIPUC approved both plans 
with only a $1 million reduction to the gas capital spending proposal. 

Rhode Island large-scale renewable contracts
In February 2019, the Company’s Rhode Island electric distribution 
company, the Narragansett Electric Company, filed with the RIPUC for 
approval of a long-term contract for output from offshore wind energy 
generation from an approximately 400 MW project to be located on the 
outer continental shelf. This contract is a voluntary obligation consistent 
with Governor Raimondo’s 1,000 MW clean energy goal for Rhode 
Island. The bid was submitted in response to the Massachusetts 
solicitation for offshore wind energy generation, and such bids were 
shared with Rhode Island. RIPUC approved the contract in May 2019.

In February 2020, the Narragansett Electric Company filed with the 
RIPUC for approval of a long-term contract for output from an 
approximately 50 MW solar facility to be located in Connecticut. 

The contract resulted from a competitive solicitation issued in 2018 to 
satisfy the Company’s obligations under the Rhode Island Long-term 
Contracting Standard. RIPUC approved the contract at a virtual open 
meeting on 27 March 2020 and the Company received its written 
decision on 11 May 2020. 

Federal Energy Regulatory Commission
Complaints on New England transmission allowed RoE 
In September 2011, December 2012, July 2014 and April 2016, a series 
of four complaints were filed with FERC against certain transmission 
owners, including our New England electricity transmission business. 
These complaints aimed to lower the base RoE, which FERC had 
authorised at 11.14% prior to the first complaint. FERC issued orders 
resolving only the first complaint, with the last order in March 2015, 
lowering the base RoE to 10.57%. A number of parties, including the 
Company, appealed FERC’s order on the first complaint to the US 
federal court. On 14 April 2017, the court vacated FERC’s order and 
remanded the first complaint back to FERC. This required FERC to 
reconsider the methodology it adopted in its order. On 5 June 2017, 
the New England Transmission Owners (NETOs), including the 
Company, submitted a filing to FERC to document the reinstatement 
of their transmission rates that had been in effect on 15 October 2014. 
FERC denied this filing and stated that, until further notice, the base RoE 
in New England must remain at the filed rate of 10.57%. On 16 October 
2018, FERC issued a Preliminary Order Directing Brief on our four New 
England RoE complaints. In this, FERC proposed a new methodology 
for determining whether an existing RoE remains just and reasonable 
and also for determining a new RoE where an existing RoE is found to 
be unjust and unreasonable. FERC also proposed to set the base RoE 
in New England at 10.41% with a 13.08% cap on incentives. Briefs were 
due in January 2019 and responses to the briefs were filed on 8 March 
2019. FERC is under no deadline to act on the briefs and it is too early 
to determine when or how FERC will come to a decision. 

On 21 November 2019, FERC issued an order addressing customer 
complaints involving the transmission RoE for the transmission owners 
in the Midcontinent Independent System Operator (MISO TOs). FERC 
issued an order on rehearing addressing the initial order on 21 May 2020. 
In those orders, FERC adopted a revised methodology for determining 
base RoEs for the MISO TOs. This differed significantly from the 
methodology and framework set forth in its 16 October 2018 preliminary 
order, which proposed a new RoE methodology in the dockets covering 
the four RoE complaints against the NETOs. On 23 December 2019, the 
NETOs filed a Supplemental Paper Hearing Brief and a Motion to 
Supplement the Record in the NETOs’ RoE dockets to respond to the 
new methodology adopted in the November 2019 MISO TOs’ order, as 
there is uncertainty as to whether the outcome in that proceeding may 
be applied to the NETOs’ cases. Further changes to the FERC RoE 
methodology applicable to the Company are possible as a result of the 
orders in the MISO TOs’ proceeding and the issues raised in pending 
pleadings in the NETOs’ proceedings. Given the significant uncertainty 
relating to FERC’s methodology, the Company is unable to predict the 
potential effect of the November 2019 and 21 May 2020 MISO TO orders 
on the NETOs’ RoE dockets or the outcome of the four complaints. 
Further, the Company cannot reasonably estimate a range of gain or 
loss for any of the four complaint proceedings.

Formula Rate 206 proceeding 
On 28 December 2015, FERC initiated a proceeding under Section 206 
of the Federal Power Act. It found that ISO-New England Transmission, 
Markets, and Services Tariff is unjust, unreasonable and unduly 
discriminatory or preferential. FERC found that ISO-New England’s tariff 
lacks adequate transparency and challenge procedures regarding the 
formula rates for ISO-NE Participating Transmission Owners (ISO-NE 
PTOs). In addition, the Commission found that the ISO-NE PTOs’ current 
Regional Network Service and Local Network Service formula rates 
appear to be unjust, unreasonable, unduly discriminatory or preferential, 
or otherwise unlawful. FERC explained that the formula rates appear to 
lack sufficient detail to determine how certain costs are derived and 
recovered in the formula rates. Accordingly, FERC established hearing 
and settlement judge procedures. Several parties are active in the 
proceeding, including FERC employees, various interested consumer 
parties, the New England States Committee on Electricity (NESCOE), 
and several municipal light departments. In August 2018, the parties to 
the proceeding agreed to the terms of a settlement and subsequently 
filed the proposed settlement with the settlement judge in the 
proceeding. It was opposed by certain municipal parties, making it a 
contested settlement. On 22 May 2019, FERC rejected the Formula 
Rate 206 settlement in its entirety and remanded the matter to the Chief 
Administrative Law Judge for hearing procedures. The parties have 
continued settlement negotiations and have been granted a suspension 
of the procedural schedule to attempt to finalise a settlement.

Internal control and risk factors 

Disclosure controls 
Working with management, including the Chief Executive and Chief 
Financial Officer, we have evaluated the effectiveness of the design and 
operation of our disclosure controls and procedures as at 31 March 
2020. Our disclosure controls and procedures are designed to provide 
reasonable assurance of achieving their objectives; however, their 
effectiveness has limitations, including the possibility of human error 
and the circumvention or overriding of the controls and procedures.

Even effective disclosure controls and procedures provide only 
reasonable assurance of achieving their objectives. Based on the 
evaluation, the Chief Executive and Chief Financial Officer concluded 
that the disclosure controls and procedures are effective to provide 
reasonable assurance that information required for disclosure in the 
reports that we file and submit under the Exchange Act is recorded, 
processed, summarised and reported as and when required and that 
such information is accumulated and communicated to our management, 
including the Chief Executive and Chief Financial Officer, as appropriate, 
to allow timely decisions regarding disclosure.

Internal control over financial reporting 
Our management, including the Chief Executive and Chief Financial 
Officer, has carried out an evaluation of our internal control over financial 
reporting pursuant to the Disclosure Guidance and Transparency Rules 
sourcebook and Section 404 of the Sarbanes-Oxley Act 2002. As required 
by Section 404, management is responsible for establishing and maintaining 
an adequate system of internal control over financial reporting (as defined 
in Rules 13a-5(f) and 15d-15(f) under the Exchange Act).

Our internal control over financial reporting is designed to provide 
reasonable assurance regarding the reliability of financial reporting 
and the preparation of financial statements for external purposes, 
in accordance with generally accepted accounting principles. 

Because of its inherent limitations, internal control over financial reporting 
may not prevent or detect misstatements. Also, projections of any evaluation 
of effectiveness to future periods are subject to the risk that controls may 
become inadequate because of changes in conditions, or that the 
degree of compliance with the policies or procedures may deteriorate.

Management’s evaluation of the effectiveness of the Company’s internal 
control over financial reporting was based on the revised Internal 
Control-Integrated Framework 2013 issued by the Committee of 
Sponsoring Organizations of the Treadway Commission. Using this 
evaluation, management concluded that our internal control over 
financial reporting was effective as at 31 March 2020.

Deloitte LLP, which has audited our consolidated financial statements for 
the year ended 31 March 2020, has also audited the effectiveness of our 
internal control over financial reporting.

During the year, there were no changes in our internal control over 
financial reporting that have materially affected it, or are reasonably likely 
to materially affect it.

Risk factors 
Management of our risks is an important part of our internal control 
environment, as we describe on pages 22 – 25. In addition to the 
principal risks listed, we face a number of inherent risks that could 
have a material adverse effect on our business, financial condition, 
results of operations and reputation, as well as the value and liquidity 
of our securities. 

Any investment decision regarding our securities and any forward-
looking statements made by us should be considered in the light of 
these risk factors and the cautionary statement set out on page 258. 
An overview of the key inherent risks we face is provided below.

Risk factors

Potentially harmful activities

Aspects of the work we do could potentially harm employees, 
contractors, members of the public or the environment. 

Potentially hazardous activities that arise in connection with our business 
include: the generation, transmission and distribution of electricity; and the 
storage, transmission and distribution of gas. Electricity and gas utilities also 
typically use and generate hazardous and potentially hazardous products and 
by-products. In addition, there may be other aspects of our operations that are 
not currently regarded or proved to have adverse effects but could become so, 
such as the effects of electric and magnetic fields.

A significant safety or environmental incident, or the failure of our safety 
processes or of our occupational health plans, as well as the breach of our 
regulatory or contractual obligations or our climate change targets, could 
materially adversely affect our results of operations and our reputation.

Safety is a fundamental priority for us and we commit significant resources 
and expenditure to ensuring process safety; to monitoring personal safety, 
occupational health and environmental performance; and to meeting our 
obligations under negotiated settlements.

Pandemics

We face risks related to health epidemics and other outbreaks. 

As seen in the context of COVID-19, pandemics and their associated counter-
measures may affect countries, communities, supply chains and markets, 
including the UK and our service territory in the US. The spread of such 
pandemics could have adverse effects on our workforce, which could affect 
our ability to maintain our networks and provide service. In addition, disruption 
of supply chains could adversely affect our systems or networks. 

Pandemics such as COVID-19 can also result in extraordinary economic 
circumstances in our markets which could negatively affect our customers’ 
ability to pay our invoices in the US or the charges payable to the system 
operators for transmission services in the UK. The suspension of debt collection 
and customer termination activities across our service area in response to such 
pandemics is likely to result in near-term lower customer collections, and could 
result in increasing levels of bad debt and associated provisions.

We are subject to laws and regulations in the UK and US governing health and 
safety matters to protect the public and our employees and contractors, who 
could potentially be harmed by these activities, as well as laws and regulations 
relating to pollution, the protection of the environment, and the use and disposal 
of hazardous substances and waste materials.

These expose us to costs and liabilities relating to our operations and properties, 
including those inherited from predecessor bodies, whether currently or formerly 
owned by us, and sites used for the disposal of our waste. 

The cost of future environmental remediation obligations is often inherently 
difficult to estimate and uncertainties can include the extent of contamination, 
the appropriate corrective actions and our share of the liability. We are 
increasingly subject to regulation in relation to climate change and are affected 
by requirements to reduce our own carbon emissions as well as to enable 
reduction in energy use by our customers. If more onerous requirements are 
imposed or our ability to recover these costs under regulatory frameworks 
changes, this could have a material adverse impact on our business, reputation, 
results of operations and financial position.

The extent to which pandemics such as COVID-19 may affect our liquidity, 
business, financial condition, results of operations and reputation will depend on 
future developments, which are highly uncertain and cannot be predicted, and 
will depend on the severity of the relevant pandemic, the scope, duration, cost to 
National Grid and overall economic impact of actions taken to contain it or treat 
its effects.

Internal control and risk factors continued

Infrastructure and IT systems

We may suffer a major network failure or interruption, or may not be 
able to carry out critical operations due to the failure of infrastructure, 
data or technology or a lack of supply. 

Operational performance could be materially adversely affected by: a failure 
to maintain the health of our assets or networks; inadequate forecasting of 
demand; inadequate record keeping or control of data or failure of information 
systems and supporting technology. This, in turn, could cause us to fail to meet 
agreed standards of service, incentive and reliability targets, or be in breach of a 
licence, approval, regulatory requirement or contractual obligation. Even incidents 
that do not amount to a breach could result in adverse regulatory and financial 
consequences, as well as harming our reputation.

Where demand for electricity or gas exceeds supply, including where we do not 
adequately forecast and respond to disruptions in energy supplies, and our 
balancing mechanisms are not able to mitigate this fully, a lack of supply to 
consumers may damage our reputation.

In addition to these risks, we may be affected by other potential events that are 
largely outside our control, such as the impact of the COVID-19 pandemic 
(including on our operations and as a result of large-scale working from home 
by our employees), weather (including as a result of climate change and major 
storms), unlawful or unintentional acts of third parties, insufficient or unreliable 
supply, or force majeure.

Law, regulation and political and economic uncertainty

Changes in law or regulation, or decisions by governmental bodies or 
regulators and increased political and economic uncertainty, could 
materially adversely affect us.

Most of our businesses are utilities or networks subject to regulation by 
governments and other authorities. Changes in law or regulation or regulatory 
policy and precedent (including any changes arising as a result of emergency 
legislation to address the COVID-19 pandemic and the UK’s exit from the 
European Union), including decisions of governmental bodies or regulators, in 
the countries or states in which we operate could materially adversely affect us. 
We may fail to deliver any one of our customer, investor and wider stakeholder 
propositions due to increased political and economic uncertainty. 

If we fail to engage in the energy policy debate, we may be unable to influence 
future energy policy and deliver our strategy. 

Weather conditions can affect financial performance, and severe weather that 
causes outages or damages infrastructure, together with our actual or perceived 
response, could materially adversely affect operational and potentially business 
performance and our reputation.

Malicious attack, sabotage or other intentional acts, including breaches of our 
cyber security, may also damage our assets (which include critical national 
infrastructure) or otherwise significantly affect corporate activities and, as a 
consequence, have a material adverse impact on our reputation, business, 
results of operations and financial condition.

Unauthorised access to, or deliberate breaches of, our IT systems may also 
lead to manipulation of our proprietary business data or customer information. 
Unauthorised access to private customer information may make us liable for a 
violation of data privacy regulations. Even where we establish business continuity 
controls and security against threats to our systems, these may not be sufficient.

Decisions or rulings concerning the following (as examples) could have a material 
adverse impact on our results of operations, cash flows, the financial condition 
of our businesses and the ability to develop those businesses in the future:
•  the RIIO-2 price controls; whether licences, approvals or agreements to 

operate or supply are granted, amended or renewed; whether consents for 
construction projects are granted in a timely manner; or whether there has 
been any breach of the terms of a licence, approval or regulatory requirement; 
and

•  timely recovery of incurred expenditure or obligations; the ability to pass 

through commodity costs; a decoupling of energy usage and revenue, and 
other decisions relating to the impact of general economic conditions on us, 
our markets and customers; implications of climate change and of advancing 
energy technologies; whether aspects of our activities are contestable; and 
the level of permitted revenues and dividend distributions for our businesses 
and in relation to proposed business development activities.

For further information, see pages 219 – 226, which explain our regulatory 
environment in detail.

Business performance

Current and future business performance may not meet our 
expectations or those of our regulators and shareholders.

Earnings maintenance and growth from our regulated gas and electricity 
businesses will be affected by our ability to meet or exceed efficiency targets 
and service quality standards set by, or agreed with, our regulators.

If we do not meet these targets and standards, or if we are not able to deliver the 
US rate plans strategy successfully, we may not achieve the expected benefits, 
our business may be materially adversely affected and our performance, results 
of operations and reputation may be materially harmed and we may be in breach 
of regulatory or contractual obligations.

Additional Information | Internal control and risk factors

Growth and business development activity

Failure to respond to external market developments and execute our 
growth strategy may negatively affect our performance. Conversely, 
new businesses or activities that we undertake alone or with partners 
may not deliver target outcomes and may expose us to additional 
operational and financial risk.

Failure to grow our core business sufficiently and have viable options for new 
future business over the longer term, or failure to respond to the threats and 
opportunities presented by emerging technology or innovation (including for 
the purposes of adapting our networks to meet the challenges of increasing 
distributed energy resources), could negatively affect the Group’s credibility 
and reputation and jeopardise the achievement of intended financial returns.

Our business development activities and the delivery of our growth ambition 
include acquisitions, disposals, joint ventures, partnering and organic investment 
opportunities, such as development activities relating to changes to the energy 
mix and the integration of distributed energy resources and other advanced 
technologies. These are subject to a wide range of both external uncertainties 
(including the availability of potential investment targets and attractive financing 
and the impact of competition for onshore transmission in both the UK and US) 
and internal uncertainties (including actual performance of our existing operating 
companies and our business planning model assumptions and ability to 
integrate acquired businesses effectively). As a result, we may suffer 
unanticipated costs and liabilities and other unanticipated effects.

Exchange rates, interest rates and commodity price indices

Changes in foreign currency rates, interest rates or commodity prices 
could materially impact earnings or our financial condition.

We have significant operations in the US and are therefore subject to the 
exchange rate risks normally associated with non-UK operations including the 
need to translate US assets, liabilities, income and expenses into sterling (our 
reporting currency).

We may also be liable for the past acts, omissions or liabilities of companies or 
businesses we have acquired, which may be unforeseen or greater than anticipated. 
In the case of joint ventures, we may have limited control over operations and our 
joint venture partners may have interests that diverge from our own. 

The occurrence of any of these events could have a material adverse impact on 
our results of operations or financial condition, and could also impact our ability 
to enter into other transactions.

In addition, our results of operations and net debt position may be affected 
because a significant proportion of our borrowings, derivative financial instruments 
and commodity contracts are affected by changes in interest rates, commodity 
price indices and exchange rates, in particular the dollar-to-sterling exchange rate. 

Furthermore, our cash flow may be materially affected as a result of settling 
hedging arrangements entered into to manage our exchange rate, interest rate 
and commodity price exposure, or by cash collateral movements relating to 
derivative market values, which also depend on the sterling exchange rate into 
the euro and other currencies.

Post-retirement benefits

We may be required to make significant contributions to fund pension 
and other post-retirement benefits.

Actual performance of scheme assets may be affected by volatility in debt and 
equity markets (including as a result of the COVID-19 pandemic). 

We participate in a number of pension schemes that together cover substantially 
all our employees. In both the UK and US, the principal schemes are DB schemes 
where the scheme assets are held independently of our own financial resources.

In the US, we also have other post-retirement benefit schemes. Estimates of the 
amount and timing of future funding for the UK and US schemes are based on 
actuarial assumptions and other factors, including: the actual and projected 
market performance of the scheme assets; future long-term bond yields; 
average life expectancies; and relevant legal requirements.

Changes in these assumptions or other factors may require us to make additional 
contributions to these pension schemes which, to the extent they are not 
recoverable under our price controls or state rate plans, could materially 
adversely affect the results of our operations and financial condition.

229

Additional Information

Financing and liquidity

An inability to access capital markets at commercially acceptable 
interest rates could affect how we maintain and grow our businesses.

Our businesses are financed through cash generated from our ongoing 
operations, bank lending facilities and the capital markets, particularly the 
long-term debt capital markets. 

Some of the debt we issue is rated by credit rating agencies, and changes 
to these ratings may affect both our borrowing capacity and borrowing costs. 
In addition, restrictions imposed by regulators may also limit how we service 
the financial requirements of our current businesses or the financing of newly 
acquired or developing businesses.

Financial markets can be subject to periods of volatility and shortages of liquidity 
– for example, as a result of unexpected political or economic events or the 
COVID-19 pandemic. If we were unable to access the capital markets or other 
sources of finance at commercially acceptable rates for a prolonged period, our 
cost of financing may increase, the discretionary and uncommitted elements of 
our proposed capital investment programme may need to be reconsidered, and 
the manner in which we implement our strategy may need to be reassessed. 

Such events could have a material adverse impact on our business, results 
of operations and prospects.

Some of our regulatory agreements impose lower limits for the long-term 
unsecured debt credit ratings that certain companies within the Group must 
hold or the amount of equity within their capital structures, including a limit 
requiring National Grid plc to hold an investment-grade long-term senior 
unsecured debt credit rating.

Customers and counterparties

Customers and counterparties may not perform their obligations.

Our operations are exposed to the risk that customers, suppliers, banks and 
other financial institutions, and others with whom we do business, will not satisfy 
their obligations, which could materially adversely affect our financial position.

This risk is significant where our subsidiaries have concentrations of receivables 
from gas and electricity utilities and their affiliates, as well as industrial customers 
and other purchasers, and may also arise where customers are unable to pay us 
as a result of increasing commodity prices or adverse economic conditions 
(including as a result of the COVID-19 pandemic).

Employees and others

We may fail to attract, develop and retain employees with the 
competencies (including leadership and business capabilities), values 
and behaviours required to deliver our strategy and vision and ensure 
they are engaged to act in our best interests.

Our ability to implement our strategy depends on the capabilities and 
performance of our employees and leadership at all levels of the business. Our 
ability to implement our strategy and vision may be negatively affected by the 
loss of key personnel (including personnel on sick leave or otherwise unable to 
work on an extended basis because of the COVID-19 pandemic) or an inability 
to attract, integrate, engage and retain appropriately qualified personnel, or if 
significant disputes arise with our employees.

In addition, some of our regulatory arrangements impose restrictions on the way 
we can operate. These include regulatory requirements for us to maintain adequate 
financial resources within certain parts of our operating businesses and may 
restrict the ability of National Grid plc and some of our subsidiaries to engage in 
certain transactions, including paying dividends, lending cash and levying charges. 

The inability to meet such requirements, or the occurrence of any such restrictions, 
may have a material adverse impact on our business and financial condition.

Our debt agreements and banking facilities contain covenants, including those 
relating to the periodic and timely provision of financial information by the issuing 
entity, and financial covenants, such as restrictions on the level of subsidiary 
indebtedness.

Failure to comply with these covenants, or to obtain waivers of those requirements, 
could in some cases trigger a right, at the lender’s discretion, to require 
repayment of some of our debt and may restrict our ability to draw upon our 
facilities or access the capital markets.

To the extent that counterparties are contracted with for physical commodities 
(gas and electricity) and they experience events that impact their own ability to 
deliver, we may suffer supply interruption as described in Infrastructure and IT 
systems on page 228.

There is also a risk to us where we invest excess cash or enter into derivatives 
and other financial contracts with banks or other financial institutions. Banks 
who provide us with credit facilities may also fail to perform under those contracts.

As a result, there may be a material adverse effect on our business, financial 
condition, results of operations and prospects.

There is a risk that an employee or someone acting on our behalf may breach 
our internal controls or internal governance framework, or may contravene 
applicable laws and regulations. This could have an impact on the results  
of our operations, our reputation and our relationship with our regulators 
and other stakeholders.

Articles of Association 
The following description is a summary of the material terms of our 
Articles of Association (Articles) and applicable English law. It is a 
summary only and is qualified in its entirety by reference to the Articles. 

Summary 
The Articles set out the Company’s internal regulations. Copies are 
available on our website and upon request. Amendments to the Articles 
have to be approved by at least 75% of those voting at a general meeting 
of the Company. Subject to company law and the Articles, the Directors 
may exercise all the powers of the Company. They may delegate 
authorities to committees and day-to-day management and decision-
making to individual Executive Directors. We set out the committee 
structure on page 68.

General 
The Company is incorporated under the name National Grid plc and is 
registered in England and Wales with registered number 4031152. Under 
the Companies Act 2006, the Company’s objects are unrestricted. 

Directors 
Under the Articles, a Director must disclose any personal interest in a 
matter and may not vote in respect of that matter, subject to certain 
limited exceptions. As permitted under the Companies Act 2006, the 
Articles allow non-conflicted Directors to authorise a conflict or potential 
conflict for a particular matter. In doing so, the non-conflicted Directors 
must act in a way they consider, in good faith, will be most likely to promote 
the success of the Company for the benefit of the shareholders as a whole.

The Directors (other than a Director acting in an executive capacity) 
are paid fees for their services. In total, these fees must not exceed 
£2,000,000 per year or any higher sum decided by an ordinary 
resolution at a general meeting of shareholders. In addition, special 
pay may be awarded to a Director who acts in an executive capacity, 
serves on a committee, performs services which the Directors consider 
to extend beyond the ordinary duties of a Director, devotes special 
attention to the business of National Grid, or goes or lives abroad on 
the Company’s behalf. Directors may also receive reimbursement for 
expenses properly incurred, and may be awarded pensions and other 
benefits. The compensation awarded to the Executive Directors is 
determined by the Remuneration Committee. Further details of 
Directors’ remuneration are set out in the Directors’ Remuneration 
Report (see pages 88 – 107).

The Directors may exercise all the powers of National Grid to borrow 
money. However, the aggregate principal amount of all the Group’s 
borrowings outstanding at any time must not exceed £35 billion or any 
other amount approved by shareholders by an ordinary resolution at 
a general meeting. At the Company’s AGM for 2020, shareholders 
will be asked to approve, by ordinary resolution, an increase in this 
amount (which has remained unchanged since the 2009 AGM) to 
£45 billion to enable the funding of growth over the medium-term in 
an efficient manner.

Directors can be appointed or removed by the Board or shareholders 
at a general meeting. Directors must stand for election at the first AGM 
following their appointment to the Board. Each Director must retire at 
least every three years, although they will be eligible for re-election. In 
accordance with best practice introduced by the UK Corporate Governance 
Code, all Directors wishing to continue in office currently offer themselves 
for re-election annually. No person is disqualified from being a Director 
or is required to vacate that office by reason of attaining a maximum age.

A Director is not required to hold shares in National Grid in order to 
qualify as a Director.

Rights, preferences and restrictions 
(i) Dividend rights 
National Grid may not pay any dividend otherwise than out of profits 
available for distribution under the Companies Act 2006 and other 
applicable provisions of English law. In addition, as a public company, 
National Grid may only make a distribution if, at the time of the distribution, 
the amount of its net assets is not less than the aggregate of its called-up 
share capital and undistributable reserves (as defined in the Companies 
Act 2006), and to the extent that the distribution does not reduce the 
amount of those assets to less than that aggregate. Ordinary shareholders 
and American Depositary Share (ADS) holders receive dividends.

Subject to these points, shareholders may, by ordinary resolution, 
declare dividends in accordance with the respective rights of the 
shareholders, but not exceeding the amount recommended by the 
Board. The Board may pay interim dividends if it considers that National 
Grid’s financial position justifies the payment. Any dividend or interest 
unclaimed for 12 years from the date when it was declared or became 
due for payment will be forfeited and revert to National Grid.

(ii) Voting rights 
Subject to any rights or restrictions attached to any shares and to any 
other provisions of the Articles, at any general meeting on a show of 
hands, every shareholder who is present in person will have one vote and, 
on a poll, every shareholder will have one vote for every share they hold. 
On a show of hands or poll, shareholders may cast votes either personally 
or by proxy. A proxy need not be a shareholder. Under the Articles, all 
substantive resolutions at a general meeting must be decided on a poll. 
Ordinary shareholders and ADS holders can vote at general meetings. 

(iii) Liquidation rights 
In a winding up, a liquidator may (in each case with the sanction of a 
special resolution passed by the shareholders and any other sanction 
required under English law): (a) divide among the shareholders the whole 
or any part of National Grid’s assets (whether the assets are of the same 
kind or not); the liquidator may, for this purpose, value any assets and 
determine how the division should be carried out as between shareholders 
or different classes of shareholders, or (b) transfer any part of the assets 
to trustees on trust for the benefit of the shareholders as the liquidator 
determines. In neither case will a shareholder be compelled to accept 
assets upon which there is a liability. 

(iv) Restrictions 
There are no restrictions on the transfer or sale of ordinary shares. Some 
of the Company’s employee share plans, details of which are contained 
in the Directors’ Remuneration Report, include restrictions on the transfer 
of ordinary shares while the ordinary shares are subject to the plan. 
Where, under an employee share plan operated by the Company, 
participants are the beneficial owners of the ordinary shares but not the 
registered owner, the voting rights may be exercised by the registered 
owner at the direction of the participant. Treasury shares do not attract a 
vote or dividends. 

(v) Variation of rights 
Subject to applicable provisions of English law, the rights attached to any 
class of shares of National Grid may be varied or cancelled. This must be 
with the written consent of the holders of three quarters in nominal value 
of the issued shares of that class, or with the sanction of a special resolution 
passed at a separate meeting of the holders of the shares of that class.

Additional Information

Shareholder information continued

General meetings 
AGMs must be convened each year within six months of the Company’s 
accounting reference date upon 21 clear days’ advance written notice. 
Under the Articles, any other general meeting may be convened 
provided at least 14 clear days’ written notice is given, subject to annual 
approval of shareholders. In certain limited circumstances, the Company 
can convene a general meeting by shorter notice. The notice must 
specify, among other things, the nature of the business to be transacted, 
the place, the date and the time of the meeting. Consistent with the UK 
government restrictions in relation to the COVID-19 pandemic, the 
Company’s AGM for 2020 will take place as a closed meeting.

Rights of non-residents 
There are no restrictions under the Articles that would limit the rights 
of persons not resident in the UK to vote in relation to ordinary shares. 

Disclosure of interests
Under the Companies Act 2006, National Grid may, by written notice, 
require a person whom it has reasonable cause to believe to be or to have 
been, in the last three years, interested in its shares to provide additional 
information relating to that interest. Under the Articles, failure to provide 
such information may result in a shareholder losing their rights to attend, 
vote or exercise any other right in relation to shareholders’ meetings.

Under the UK Disclosure Guidance and Transparency Rules (DTR) 
sourcebook, there is also an obligation on a person who acquires or 
ceases to have a notifiable interest in shares in National Grid to notify the 
Company of that fact. The disclosure threshold is 3% and disclosure is 
required each time the person’s direct and indirect holdings reach, 
exceed or fall below each 1% threshold thereafter.

The UK City Code on Takeovers and Mergers imposes strict disclosure 
requirements regarding dealings in the securities of an offeror or offeree 
company, and also on their respective associates, during the course of an 
offer period. Other regulators in the UK, US and elsewhere may have, or 
assert, notification or approval rights over acquisitions or transfers of shares.

Depositary payments to the Company 
The Depositary (The Bank of New York Mellon) reimburses the Company 
for certain expenses it incurs in relation to the ADS programme. The 
Depositary also pays the standard out-of-pocket maintenance costs for 
the ADSs, which consist of the expenses for the mailing of annual and 
interim financial reports, printing and distributing dividend cheques, the 
electronic filing of US federal tax information, mailing required tax forms, 
stationery, postage, facsimiles and telephone calls. It also reimburses 
the Company for certain investor relationship programmes or special 
investor relations promotional activities. There are limits on the amount of 
expenses for which the Depositary will reimburse the Company, but the 
amount of reimbursement is not necessarily tied to the amount of fees 
the Depositary collects from investors. 

For the period 16 May 2019 to 17 June 2020, the Company received a 
total of $1,835,589.41 in reimbursements from the Depositary consisting 
of $1,225,480.47 and $610,108.94 received in October 2019 and 
February 2020 respectively. Fees that are charged on cash dividends 
will be apportioned between the Depositary and the Company.

Any questions from ADS holders should be directed to The Bank of 
New York Mellon at the contact details on page 257.

Description of securities other than equity securities: 
Depositary fees and charges 
The Depositary collects fees by deducting them from the amounts 
distributed or by selling a portion of distributable property for: 
•  delivery and surrender of ADSs directly from investors depositing 

shares or surrendering ADSs for the purpose of withdrawal or from 
intermediaries acting for them; and

•  making distributions to investors (including, it is expected, cash 

dividends).

The Depositary may generally refuse to provide fee-attracting services 
until its fees for those services are paid.

Persons depositing or 
withdrawing shares must pay:

For:

$5.00 per 100 ADSs  
(or portion of 100 ADSs)

Registration or transfer fees

Expenses of the Depositary 

Taxes and other governmental 
charges the Depositary or the 
Custodian has to pay on any ADS or 
share underlying an ADS, for example, 
stock transfer taxes, stamp duty or 
withholding taxes

Issuance of ADSs, including 
issuances resulting from a 
distribution of shares or rights or 
other property; cancellation of 
ADSs for the purpose of 
withdrawal, including if the Deposit 
agreement terminates; and 
distribution of securities 
distributed to holders of deposited 
securities that are distributed by 
the Depositary to ADS holders.

Transfer and registration of shares 
on our share register to or from the 
name of the Depositary or its 
agent when they deposit or 
withdraw shares.

Cable, telex and facsimile 
transmissions (when expressly 
provided in the Deposit 
agreement); and converting 
foreign currency to dollars.

As necessary.

The Company’s Deposit agreement under which the ADSs are issued 
allows a fee of up to $0.05 per ADS to be charged for any cash distribution 
made to ADS holders, including cash dividends. ADS holders who receive 
cash in relation to the 2019/20 final dividend will be charged a fee of $0.02 
per ADS by the Depositary prior to distribution of the cash dividend. 

Documents on display
National Grid is subject to the US Securities and Exchange Commission 
(SEC) reporting requirements for foreign companies. The Company’s 
Form 20-F and other filings can be viewed on the National Grid website 
as well as the SEC website at www.sec.gov.

Events after the reporting period
In the period between 31 March 2020 and 17 June 2020, there have 
continued to be substantial environmental, economic and social 
changes in both the UK and US. As described further in the Strategic 
Report, these have had, and will continue to have, significant 
ramifications for the Group. Other than in respect of those areas where 
forward-looking forecasts are relevant (notably goodwill impairment 
reviews (note 11), expected credit losses on financial instruments 
including trade receivables (notes 19 and 32) and the presumption of the 
going concern basis generally (note 1)), none of these developments 
have caused adjustment to the financial statements.

Exchange controls 
There are currently no UK laws, decrees or regulations that restrict the 
export or import of capital, including, but not limited to, foreign exchange 
control restrictions, or that affect the remittance of dividends, interest or 
other payments to non-UK resident holders of ordinary shares except as 
otherwise set out in Taxation on pages 234 and 235 and except in respect 
of the governments of and/or certain citizens, residents or bodies of certain 
countries (described in applicable Bank of England Notices or European 
Union Council Regulations in force as at the date of this document).

Material interests in shares
As at 31 March 2020, National Grid had been notified of the following 
holdings in voting rights of 3% or more in the issued share capital of 
the Company:

disclosed.

As at 17 June 2020, no further notifications have been received.

The rights attached to ordinary shares are detailed on page 231. All ordinary 
shares and all major shareholders have the same voting rights. The 
Company is not, to the best of its knowledge, directly or indirectly controlled. 

Share capital
As at 17 June 2020, the share capital of the Company consists of 
ordinary shares of 12204/473 pence nominal value each and ADSs, which 
represent five ordinary shares each. 

Authority to purchase shares
Shareholder approval was given at the 2019 AGM to purchase up to 
10% of the Company’s share capital (being 341,188,512 ordinary shares). 
The Directors intend to seek shareholder approval to renew this authority 
at the 2020 AGM. 

In some circumstances, the Company may find it advantageous to have 
the authority to purchase its own shares in the market, where the Directors 
believe this would be in the interests of shareholders generally. The 
Directors believe that it is an important part of the financial management of 
the Company to have the flexibility to repurchase issued shares to manage 
its capital base, including actively managing share issuances from the 
operation of the scrip dividend scheme. It is expected that repurchases to 
manage share issuances under the scrip dividend scheme will not exceed 
2.5% of the issued share capital (excluding treasury shares) per annum. 

When purchasing shares, the Company has taken, and will continue 
to take, into account market conditions prevailing at the time, other 
investment and financing opportunities, and the overall financial position 
of the Company.

At the 2019 AGM, the Company sought authority to purchase ordinary 
shares in the capital of the Company as part of the management of the 
dilutive effect of share issuances under the scrip dividend scheme. 
During the year, the Company did not purchase any of its own shares.

3. Called-up share capital of 3,780,237,016 ordinary shares as at the date of this report.

As at the date of this report, the Company held 270,105,462 ordinary 
shares as treasury shares. This represented 7.15% of the Company’s 
called-up share capital.

Authority to allot shares
Shareholder approval was given at the 2019 AGM to allot shares of up 
to one third of the Company’s share capital. The Directors are seeking 
this same level of authority this year. The Directors consider that the 
Company will have sufficient flexibility with this level of authority to 
respond to market developments and that this authority is in line with 
investor guidelines.

The Directors currently have no intention of issuing new shares or of 
granting rights to subscribe for or convert any security into shares. This is 
except in relation to, or in connection with, the operation and management 
of the Company’s scrip dividend scheme and the exercise of options 
under the Company’s share plans. No issue of shares will be made that 
would effectively alter control of the Company without the sanction of 
shareholders in a general meeting.

The Company expects to actively manage the dilutive effect of share 
issuance arising from the operation of the scrip dividend scheme. In some 
circumstances, additional shares may be allotted to the market for this 
purpose under the authority provided by this resolution. Under these 
circumstances, it is expected that the associated allotment of new shares 
(or rights to subscribe for or convert any security into shares) will not exceed 
1% of the issued share capital (excluding treasury shares) per annum.

Dividend waivers 
The trustee of the National Grid Employee Share Trust, which is 
independent of the Company, waived the right to dividends paid during 
the year. They have also agreed to waive the right to future dividends, 
in relation to the ordinary shares and ADSs held by the trust. 

Under the Company’s ADS programme, the right to dividends in relation 
to the ordinary shares underlying the ADSs was waived during the year, 
under an arrangement whereby the Company pays the monies to satisfy 
any dividends separately to the Depositary for distribution to ADS 
holders entitled to the dividend. This arrangement is expected to 
continue for future dividends.

Share information
National Grid ordinary shares are listed on the London Stock Exchange 
under the symbol NG. The ADSs are listed on the New York Stock 
Exchange under the symbol NGG.

Taxation
The discussion in this section provides information about certain US 
federal income tax and UK tax consequences for US Holders (defined 
below) of owning ADSs and ordinary shares. A US Holder is the 
beneficial owner of ADSs or ordinary shares who:
•  is for US federal income tax purposes (i) an individual citizen or 

resident of the United States; (ii) a corporation created or organised 
under the laws of the United States, any state thereof or the District of 
Columbia; (iii) an estate, the income of which is subject to US federal 
income tax without regard to its source; or (iv) a trust, if a court within 
the United States is able to exercise primary supervision over the 
administration of the trust and one or more US persons have the 
authority to control all substantial decisions of the trust, or the trust 
has elected to be treated as a domestic trust for US federal income 
tax purposes;

•  is not resident or ordinarily resident in the UK for UK tax purposes; 

and

•  does not hold ADSs or ordinary shares in connection with the 

conduct of a business or the performance of services in the UK 
or otherwise in connection with a branch, agency or permanent 
establishment in the UK.

This discussion is not a comprehensive description of all the US federal 
income tax and UK tax considerations that may be relevant to any 
particular investor (including consequences under the US alternative 
minimum tax or net investment income tax). Neither does it address 
state, local or other tax laws. National Grid has assumed that shareholders, 
including US Holders, are familiar with the tax rules applicable to 
investments in securities generally and with any special rules to which 
they may be subject. This discussion deals only with US Holders who 
hold ADSs or ordinary shares as capital assets. It does not address the 
tax treatment of investors who are subject to special rules. Such 
investors may include: 
•  financial institutions; 
•  insurance companies;
•  dealers in securities or currencies;
•  investors who elect mark-to-market treatment;
•  entities treated as partnerships or other pass-through entities and 

their partners;

•  individual retirement accounts and other tax-deferred accounts;
•  tax-exempt organisations;
•  investors who own (directly or indirectly) 10% or more of our shares 

(by vote or value);

•  investors who hold ADSs or ordinary shares as a position in 
a straddle, hedging transaction or conversion transaction; 

•  individual investors who have ceased to be resident in the UK for 

a period of five years or less;

•  persons that have ceased to be US citizens or lawful permanent 

residents of the US; and

•  US Holders whose functional currency is not the US dollar. 

The statements regarding US and UK tax laws and administrative 
practices set forth below are based on laws, treaties, judicial decisions 
and regulatory interpretations that were in effect on the date of this 
document. These laws and practices are subject to change without 
notice, potentially with retroactive effect. In addition, the statements set 
forth below are based on the representations of the Depositary and 
assume that each party to the Deposit agreement will perform its 
obligations thereunder in accordance with its terms. 

US Holders of ADSs generally will be treated as the owners of the 
ordinary shares represented by those ADSs for US federal income tax 
purposes. For the purposes of the Tax Convention, the Estate Tax 
Convention and UK tax considerations, this discussion assumes that a 
US Holder of ADSs will be treated as the owner of the ordinary shares 
represented by those ADSs. HMRC has stated that it will continue to 
apply its long-standing practice of treating a holder of ADSs as holding 
the beneficial interest in the ordinary shares represented by the ADSs; 
however, we note that this is an area of some uncertainty and may be 
subject to change.

US Holders should consult their own advisors regarding the tax 
consequences of buying, owning and disposing of ADSs or ordinary 
shares depending on their particular circumstances, including the effect 
of any state, local or other tax laws.

Additional Information | Shareholder information

Taxation of dividends 
The UK does not currently impose a withholding tax on dividends paid 
to US Holders. 

US Holders should assume that any cash distribution paid by us with 
respect to ADSs or ordinary shares will be reported as dividend income 
for US federal income tax purposes. While dividend income received 
from non-US corporations is generally taxable to a non-corporate US 
Holder as ordinary income for US federal income tax purposes, dividend 
income received by a non-corporate US Holder from us generally will be 
taxable at the same favourable rates applicable to long-term capital 
gains provided (i) either: (a) we are eligible for the benefits of the Tax 
Convention or (b) ADSs or ordinary shares are treated as ‘readily 
tradable’ on an established securities market in the United States; and (ii) 
we are not, for our taxable year during which the dividend is paid or the 
prior year, a passive foreign investment company for US federal income 
tax purposes (a PFIC), and certain other requirements are met. We 
expect that our shares will be treated as ‘readily tradable’ on an 
established securities market in the United States as a result of the 
trading of ADSs on the New York Stock Exchange. We also believe we 
are eligible for the benefits of the Tax Convention. 

Based on our audited financial statements and the nature of our 
business activities, we believe that we were not treated as a PFIC for US 
federal income tax purposes with respect to our taxable year ending 
31 March 2019. In addition, based on our current expectations regarding 
the value and nature of our assets, the sources and nature of our 
income, and the nature of our business activities, we do not anticipate 
becoming a PFIC in the foreseeable future.

Dividends received by corporate US Holders with respect to ADSs or 
ordinary shares will not be eligible for the dividends-received deduction 
that is generally allowed to corporations.

Taxation of capital gains 
Subject to specific rules relating to assets that derive at least 75% of 
their value from UK land, US Holders will not be subject to UK taxation 
on any capital gain realised on the sale or other disposition of ADSs or 
ordinary shares.

Provided that we are not a PFIC for any taxable year during which 
a US Holder holds their ADSs or ordinary shares, upon a sale or other 
disposition of ADSs or ordinary shares, a US Holder generally will 
recognise a capital gain or loss for US federal income tax purposes that 
is equal to the difference between the US dollar value of the amount 
realised on the sale or other disposition and the US Holder’s adjusted 
tax basis in the ADSs or ordinary shares. Such capital gain or loss 
generally will be long-term capital gain or loss if the ADSs or ordinary 
shares were held for more than one year. For non-corporate US Holders, 
long-term capital gain is generally taxed at a lower rate than ordinary 
income. A US Holder’s ability to deduct capital losses is subject to 
significant limitations. 

US information reporting and backup withholding tax 
Dividend payments made to US Holders and proceeds paid from the 
sale, exchange, redemption or disposal of ADSs or ordinary shares to 
US Holders may be subject to information reporting to the US Internal 
Revenue Service (IRS). Such payments may be subject to backup 
withholding taxes if the US Holder fails to provide an accurate taxpayer 
identification number or certification of exempt status or fails to comply 
with applicable certification requirements.

US Holders should consult their tax advisors about these rules and any 
other reporting obligations that may apply to the ownership or disposition 
of ADSs or ordinary shares. Such obligations include reporting 
requirements related to the holding of certain foreign financial assets.

UK stamp duty and stamp duty reserve tax (SDRT)
Transfers of ordinary shares – SDRT at the rate of 0.5% of the 
amount or value of the consideration will generally be payable on any 
agreement to transfer ordinary shares that is not completed using a duly 
stamped instrument of transfer (such as a stock transfer form).

The SDRT liability will be cancelled where an instrument of transfer is 
executed and duly stamped before the expiry of the six-year period 
beginning with the date on which the agreement is made. If a claim is 
made within the specified period, any SDRT which has been paid will be 
refunded. SDRT is due whether or not the agreement or transfer is made 
or carried out in the UK and whether or not any party to that agreement 
or transfer is a UK resident.

Purchases of ordinary shares completed using a stock transfer form will 
generally result in a UK stamp duty liability at the rate of 0.5% (rounded 
up to the nearest £5) of the amount or value of the consideration. 
Paperless transfers under the CREST paperless settlement system will 
generally be liable to SDRT at the rate of 0.5%, and not stamp duty. 
SDRT is generally the liability of the purchaser, and UK stamp duty is 
usually paid by the purchaser or transferee.

Transfers of ADSs – no UK stamp duty will be payable on the 
acquisition or transfer of existing ADSs or beneficial ownership of ADSs, 
provided that any instrument of transfer or written agreement to transfer 
is executed outside the UK and remains at all times outside the UK.

An agreement for the transfer of ADSs in the form of American 
Depositary Receipts will not result in an SDRT liability. A charge to stamp 
duty or SDRT may arise on the transfer of ordinary shares to the 
Depositary or The Bank of New York Mellon as agent of the Depositary 
(the Custodian).

The rate of stamp duty or SDRT will generally be 1.5% of the value of 
the consideration or, in some circumstances, the value of the ordinary 
shares concerned. However, there is no 1.5% SDRT charge on the issue 
of ordinary shares (or, where it is integral to the raising of new capital, 
the transfer of ordinary shares) to the Depositary or the Custodian. 

The Depositary will generally be liable for the stamp duty or SDRT. Under 
the terms of the Deposit Agreement, the Depositary will charge any tax 
payable by the Depositary or the Custodian (or their nominees) on the 
deposit of ordinary shares to the party to whom the ADSs are delivered 
against such deposits. If the stamp duty is not a multiple of £5, the duty 
will be rounded up to the nearest multiple of £5.

UK inheritance tax
An individual who is domiciled in the US for the purposes of the Estate 
Tax Convention and who is not a UK national for the purposes of the 
Estate Tax Convention will generally not be subject to UK inheritance tax 
in respect of (i) the ADSs or ordinary shares on the individual’s death or 
(ii) a gift of the ADSs or ordinary shares during the individual’s lifetime. 
This is not the case where the ADSs or ordinary shares are part of the 
business property of the individual’s permanent establishment in the UK 
or relate to a fixed base in the UK of an individual who performs 
independent personal services.

Special rules apply to ADSs or ordinary shares held in trust. 

In the exceptional case where the ADSs or shares are subject both to 
UK inheritance tax and to US federal gift or estate tax, the Estate Tax 
Convention generally provides for the tax paid in the UK to be credited 
against tax paid in the US or vice versa.

All-employee share plans
The Company has a number of all-employee share plans as described 
below, which operated during the year. These allow UK or US-based 
employees to participate in tax-advantaged plans and to become 
shareholders in National Grid.

Sharesave
UK employees are eligible to participate in the Sharesave plan. Under 
this plan, participants may contribute between £5 and £500 in total each 
month, for a fixed period of three years, five years or both. Contributions 
are taken from net salary. At the end of the three or five years, 
participants may use their savings to purchase ordinary shares in 
National Grid at a 20% discounted option price, which is set at the time 
of each annual Sharesave launch. 

Share Incentive Plan (SIP)
UK employees are eligible to participate in the SIP. Contributions up to 
£150 per month are deducted from participants’ gross salary and used 
to purchase ordinary shares in National Grid each month. The shares are 
placed in a UK resident trust. 

US Incentive Thrift Plans
Thrift Plans are open to all US employees of participating National Grid 
companies; these are tax-advantaged savings plans (commonly referred 
to as 401k plans). These are defined contribution (DC) pension plans 
that give participants the opportunity to invest up to applicable federal 
salary limits. The federal limits for calendar year 2019 were: for pre-tax 
contributions, a maximum of 50% of salary limited to $19,000 for those 
under the age of 50 and $25,000 for those aged 50 and above; for 
post-tax contributions, up to 15% of salary. The total amount of 
employee contributions (pre-tax and post-tax) could not exceed 50% of 
compensation, and was further subject to the combined federal annual 
contribution limit of $56,000. For the calendar year 2020, participants 
may invest up to the applicable federal salary limits: for pre-tax 
contributions, this is a maximum of 50% of salary limited to $19,500 for 
those under the age of 50 and $26,000 for those aged 50 and above; for 
post-tax contributions, this is up to 15% of salary. The total amount of 
employee contributions (pre-tax and post-tax) may not exceed 50% of 
compensation, and is further subject to the combined federal annual 
contribution limit of $57,000.

Employee Stock Purchase Plan (ESPP)
Employees of National Grid’s participating US companies are eligible to 
participate in the ESPP (commonly referred to as a 423b plan). Eligible 
employees have the opportunity to purchase ADSs in National Grid on a 
monthly basis at a 15% discounted price. Under the plan, employees 
may contribute up to 20% of base pay each year, up to a maximum 
annual contribution of $18,888, to purchase ADSs.

Change of control provisions
No compensation would be paid for loss of office of Directors on a 
change of control of the Company. As at 31 March 2020, the Company 
had borrowing facilities of £4.2 billion available to it with a number of 
banks, which, on a change of control of the Company following a 
takeover bid, may alter or terminate; however, the Company is currently 
not drawing on any of such borrowing facilities. All of the Company’s 
share plans contain provisions relating to a change of control. 
Outstanding awards and options would normally vest and become 
exercisable on a change of control, subject to the satisfaction of any 
performance conditions at that time. In the event of a change of control 
of the Company, a number of governmental and regulatory consents 
or approvals are likely to be required, arising from laws or regulations 
of the UK, the US or the EU. Such consents or approvals may also be 
required for acquisitions of equity securities that do not amount to a 
change of control.

No other agreements that take effect, alter or terminate upon a change 
of control of the Company following a takeover bid are considered to be 
significant in terms of their potential impact on the business as a whole.

Code of Ethics 
In accordance with US legal requirements, the Board has adopted a 
Code of Ethics for senior financial professionals. This Code is available 
on our website: www.nationalgrid.com (where any amendments or waivers 
will also be posted). There were no amendments to, or waivers of, our 
Code of Ethics during the year.

Conflicts of interest
In accordance with the Companies Act 2006, the Board has a policy and 
procedure in place for the disclosure and authorisation (if appropriate) of 
actual and potential conflicts of interest. The Board continues to monitor 
and note possible conflicts of interest that each Director may have. The 
Directors are regularly reminded of their continuing obligations in relation 
to conflicts, and are required to review and confirm their external 
interests annually. During the year ended 31 March 2020, no new actual 
or potential conflicts of interest were identified that required approval by 
the Board. The Board has considered and noted a number of situations 
in relation to which no actual conflict of interest was identified. Due to 
current ongoing contractual negotiations that the Company has with 
Costain plc, the situational conflict that Paul Golby has by virtue of being 
a Non-executive Director of the Company and Chairman of Costain plc 
has been kept under constant review during the year and Paul Golby 
has been recused of all discussions in relation to contractual issues 
with Costain plc. He has also confirmed to us in writing that the same 
arrangements are in place in Costain plc. 

Corporate governance practices: differences from New York 
Stock Exchange (NYSE) listing standards
The Company is listed on the NYSE and is therefore required to disclose 
differences in its corporate governance practices adopted as a UK listed 
company, compared with those of a US company.

The corporate governance practices of the Company are primarily based 
on the requirements of the Corporate Governance Code 2018 but 
substantially conform to those required of US companies listed on the 
NYSE. The following is a summary of the significant ways in which the 
Company’s corporate governance practices differ from those followed 
by US companies under Section 303A Corporate Governance 
Standards of the NYSE.

The NYSE rules and the Code apply different tests for the independence 
of Board members.

The NYSE rules require a separate nominating/corporate governance 
committee composed entirely of independent Directors. There is no 
requirement for a separate corporate governance committee in the UK. 
Under the Company’s corporate governance policies, all Directors on 
the Board discuss and decide upon governance issues, and the 
Nominations Committee makes recommendations to the Board with 
regard to certain responsibilities of a corporate governance committee.

The NYSE rules require listed companies to adopt and disclose 
corporate governance guidelines. While the Company reports 
compliance with the Code in each Annual Report and Accounts, 
the UK requirements do not require the Company to adopt and 
disclose separate corporate governance guidelines.

The NYSE rules require a separate audit committee composed of 
at least three independent members. While the Company’s Audit 
Committee exceeds the NYSE’s minimum independent Non-executive 
Director membership requirements, it should be noted that the quorum 
for a meeting of the Audit Committee, of two independent Non-executive 
Directors, is less than the minimum membership requirements under 
the NYSE rules.

The NYSE rules require a compensation committee composed 
entirely of independent Directors, and prescribe criteria to evaluate the 
independence of the committee’s members and its ability to engage 
external compensation advisors. While the Code prescribes different 
independence criteria, the Non-executive Directors on the Company’s 
Remuneration Committee have each been deemed independent by 
the Board under the NYSE rules. Although the evaluation criteria for 
appointment of external advisors differ under the Code, the Remuneration 
Committee is solely responsible for the appointment, retention and 
termination of such advisors.

Directors’ indemnity
The Company has arranged, in accordance with the Companies Act 
2006 and the Articles of Association, qualifying third-party indemnities 
against financial exposure that Directors may incur in the course of their 
professional duties. Equivalent qualifying third-party indemnities were, 
and remain, in force for the benefit of those Directors who stood down 
from the Board in prior financial years for matters arising when they were 
Directors of the Company. Alongside these indemnities, the Company 
places Directors’ and Officers’ liability insurance cover for each Director. 

Material contracts 
Each of our Executive Directors has a Service Agreement and each 
Non-executive Director has a Letter of Appointment. Apart from these, 
no contract (other than contracts entered into in the ordinary course of 
business) has been entered into by the Group within the two years 
immediately preceding the date of this report that is, or may be, material, 
or that contains any provision under which any member of the Group 
has any obligation or entitlement that is material to the Group at the date 
of this report.

Employees 
We negotiate with recognised unions. It is our policy to maintain well 
developed communications and consultation programmes. Other than 
the implementation of the Massachusetts workforce contingency plan 
in June 2018 there have been no material disruptions to our operations 
from labour disputes during the past five years. The agreement under 
dispute between the Company and the Massachusetts Gas unions was 
satisfactorily renegotiated in January 2019. National Grid believes that 
it can conduct its relationships with trade unions and employees in a 
satisfactory manner. Further details on the Company’s colleagues can 
be found on pages 52 – 54. 

Human rights
Respect for human rights is incorporated into our employment practices 
and our core values, which are integral to our Code of Ethical Business 
Conduct. The way in which we conduct ourselves allows us to build trust 
with the people with whom we work. As a global utility company, we earn 
this trust by doing things in the right way, complying with the laws of the 
countries in which we do business while building our reputation as a 
responsible company that our stakeholders want to do business with and 
our employees want to work for. Although we do not have specific policies 
relating to human rights, slavery or human trafficking, our commitment is 
guided by our Global Supplier Code of Conduct (GSCoC) that integrates 
human rights into the way we do business throughout our supply chain 
alongside other areas of sustainability. This Code outlines our values and 
expectations to ensure we treat people with respect and protect their 
human rights, protect the environment and preserve natural resources 
and positively impact the interests of the communities we serve and from 
which we procure goods and services. Through our GSCoC, we expect 
our suppliers to act in accordance with the highest ethical standards and 
comply with all the relevant laws, regulations and licences relating to 
their business, as well as adhere to the Principles of the United Nations 
Global Compact, the International Labour Organization (ILO) minimum 
standards, the Ethical Trading Initiative (ETI) Base Code, the UK Modern 
Slavery Act 2015, Trafficking and Violence Protection Act 2000 and, for 
our UK suppliers, the requirements of the Living Wage Foundation.

Political donations and expenditure
At this year’s AGM, the Directors will again seek authority from 
shareholders, on a precautionary basis, for the Company and its 
subsidiaries to make donations to registered political parties and other 
political organisations and/or incur political expenditure as such terms 
are defined in the Companies Act 2006. In each case, donations will be 
in amounts not exceeding £125,000 in aggregate. The definitions of 
these terms in the Companies Act 2006 are very wide. As a result, this 
can cover bodies such as those concerned with policy review, law 
reform and the representation of the business community. It could 
include special interest groups, such as those involved with the 
environment, which the Company and its subsidiaries might wish to 
support, even though these activities are not designed to support or 
influence support for a particular party. The Companies Act 2006 states 
that all-party parliamentary groups are not political organisations for 
these purposes, meaning the authority to be sought from shareholders 
is not relevant to interactions with such groups. The Company has no 
intention of changing its current practice of not making political 
donations or incurring political expenditure within the ordinary meaning 
of those words. This authority is, therefore, being sought to ensure that 
none of the Company’s activities inadvertently infringe these rules. 

National Grid made no political donations in the UK or the EU during 
the year, including donations as defined for the purposes of the Political 
Parties, Elections and Referendums Act 2000. National Grid USA and its 
affiliated New York and federal political action committees (PAC) made 
political donations in the US totalling $46,050 (£36,978) during the year. 
National Grid USA’s affiliated New York PAC was funded partly by 
contributions from National Grid USA and certain of its subsidiaries and 
partly by voluntary employee contributions. National Grid USA’s affiliated 
federal PAC was funded wholly by voluntary employee contributions.

Research, development and innovation activity
Investment in research and development during the year for the Group 
was £14 million (2018/19: £19 million; 2017/18: £13 million). Due to the 
way in which we work with a large number of partners on new ideas, 
our disclosed research and development expenditure is lower than the 
overall contribution we make to the industry. We only disclose directly 
incurred expenditure, and not those amounts our partners contribute 
to joint or collaborative projects. Collaborating across the industry has 
played a crucial role in our ability to develop new programmes and 
deliver value to our stakeholders throughout 2019/20. 

Continued collaboration and stakeholder engagement have driven 
the research programmes for ET innovation. Our engagement with 
stakeholders as part of webinars, podcasts, formal meetings, 
conferences and dissemination events has been instrumental to 
developing our strategies including our overall innovation strategy 
as well as technology and asset-related innovation strategies.

As a result, our project portfolio has been developed around the 
themes of delivering cleaner and cheaper energy. Our commitment to 
the ‘Net Zero’ target for 2050 has provided the focus for our research 
programme on carbon emission reduction. We have started 
cross-sector collaboration in order to drive a whole-system approach 
to decarbonising key sectors such as heat, transport and industry. 
Our Zero2050 project in South Wales has brought diverse stakeholders 
from utilities, industry, academia, SMEs, consultants and government 
together to design a pathway to decarbonisation for South Wales that 
delivers best value to consumers.

Research and Development (R&D) work in the US focused on the 
advancement of products, processes, systems and work methods 
that may be new to National Grid. This is accomplished by working 
with internal departments to identify where strategic R&D investment is 
needed and is likely to prove beneficial. To achieve these goals, we work 
in collaboration with technical organisations, academia and vendors in 
the energy sector that align with our goals and objectives to provide a 
safe, reliable, efficient and clean service. This collaboration has also 
helped inform our strategic direction in response to jurisdictional 
requests for electric modernisation (Grid Modernisation in 
Massachusetts, Rhode Island and Reforming the Energy Vision (REV) 
in New York). We continue to focus our R&D on increasing public safety, 
protecting our workforce and reducing the cost of the work we perform. 

In 2019/20, we continued to invest and participate in several significant 
pilot projects with the intention of obtaining operational knowledge and 
experience of technology-driven system impacts. Below are a few 
examples of our R&D projects:

US Electricity:
•  In Massachusetts under our ‘Solar Phase II’ programme, we 

contracted and built 15.27 MW of company-owned photovoltaics 
facilities. The objective is to better understand the real-world impact 
advanced technologies can bring to the grid; such as reduced 
customer interconnection costs and time; increasing hosting capacity; 
and improving the distribution system’s overall power quality and 
reliability. We partnered with the Electric Power Research Institute 
(EPRI), Sandia National Laboratories (Sandia) and Fraunhofer 
Gesellschaft (Fraunhofer);

•  With the EPRI, we explored the value of customised smart inverter 
settings and advanced metering at the Point of Common Coupling 
(PCC) and published our findings in a white paper titled 
‘Recommended Smart Inverter Settings for Grid Support and Test 
Plan: Interim Report’. We also worked with them to calculate the 
severity of PV Arc Flashes, of which the team shared their findings 
in a paper titled ‘DC Arc Flash on Photovoltaic Equipment’;
•  With National Grid’s support, Sandia initiated an Advanced 

Distribution Management Systems (ADMS) to optimise commands 
to allow PV penetration of 50% or greater. Our work was published 
in a paper titled ‘Optimal Distribution System Voltage Regulation using 
State Estimation and DER Grid-Support Functions’;

•  Under the support of the US Department of Energy, the Fraunhofer 

CSE-led project, called ‘SunDial’, we created a system that optimally 
manages facility loads and energy storage charging and discharging 
with PV to mitigate potential problems due to intermittency and large 
ramps in generation;

•  In the ‘Solar Phase III’ programme, we developed seven additional 
sites each equipped with a unique combination of smart inverters, 
energy storage, advanced metering, plant level control, and other 
equipment with features beyond today’s industry standards. We will be 
testing these new technologies on a variety of distribution circuits; and 

•  Last year, we completed two New York REV pilot projects:

•  Fruit Belt Neighbourhood Solar and Community Resilience. 
This year we have completed an additional New York REV 
demonstration project; and 

•  The Distributed System Platform (DSP) REV demonstration project 
tested a small-scale distribution system energy market involving 
customer-owned DERs to support the Distribution System Operator 
(DSO) concept.

We are also increasing research into decarbonising our own operations 
and preparing our network for the changes we need to make to 
accommodate a fully decarbonised energy sector. We have worked 
with our partners on several projects, investigating ways to eliminate 
greenhouse gases from our gas-insulated equipment as well as the 
reduction of our carbon footprint relating to our construction work. 
Our future network will need to accommodate more renewable energy 
sources and other converter-based connections and equipment. 
Providing the infrastructure for a secure, efficient and reliable network 
requires an increased understanding of network stability with reduced 
inertia in the system. We have started four projects investigating the 
impacts of reduced inertia, potential controller interactions and reduced 
fault levels. As part of these projects we are developing our capabilities 
to accurately model the electricity transmission network and are 
developing schemes to mitigate the impacts on system stability and 
protection performance.

The second key aspect that our stakeholder engagement has 
highlighted is the delivery of cheaper energy. This has been implemented 
in our research programme on optimised asset management and 
monitoring as well as the digitisation of operational technology, considering 
in particular, cyber security in a context of increasing cyber threats.

As a key enabler for future innovation we have continued the delivery 
of our Deeside Centre for Innovation. Significant progress has been 
made with the completion of the control building, good progress on 
the construction of the overhead line test area and detailed design 
for the substation area, which notably includes a trial for construction 
with cement-free concrete.

The ESO has been innovating to make sure the electricity network 
operates safely and efficiently around the clock. Innovation is key to 
creating a sustainable, low-carbon electricity system for the future that 
will help the UK meet its net zero commitments. We refresh our strategy 
and innovation priorities annually, based on consultation with our 
stakeholders and this ensures we continue to focus innovation funding 
only on the most effective projects which can deliver consumer benefits. 
Next year will see us continue delivering large-scale ESO-led innovation 
projects, including Distributed ReStart, a £10 million Network Innovation 
Competition (NIC) project with SP Energy Networks and specialist 
energy consultancy TNEI. In a world first, this project will develop and 
demonstrate coordination of DERs to provide a safe and effective Black 
Start service at lower cost to consumers.

Gas Transmission innovation has continued to focus on developing 
innovation programmes across core areas such as net zero, safety, 
reliability and asset health, and embedding these in the business, while 
also preparing to deliver the energy network of the future and facilitate 
UK decarbonisation. Highlights from the year include: 
•  expanding our focus on hydrogen with a number of new projects, 

including Hydrogen Injection into the NTS, looking at the requirements 
to carry out a physical trial of hydrogen in the NTS;

•  the Monitoring of Real-Time Fugitive Emissions project, looking at 
developing a robust measurement protocol and a new, low-cost, 
distributed sensor scheme to monitor fugitive emissions;

•  the Spatial GB Clean Heat model, a National Grid-led collaborative 
project with the gas distribution networks to develop an integrated, 
cross-vector heat decarbonisation model of the whole heating system 
within GB to optimise future investment plans;

•  launching a number of innovation calls with the Energy Innovation 

Centre (EIC), reaching out to innovators and small and medium-sized 
enterprises (SMEs) to find new technologies and solutions to some of 
our biggest challenges on the NTS;

•  the GRAID ART project, which will investigate the addition of Acoustic 
Resonance Technology (ART) onto the GRAID robotic platform to 
enhance our underground pipeline inspections, provide robust data 
about their condition and reduce maintenance and repair costs;

•  the installation of the Composite Transition Pieces at Peterborough 

and Huntingdon; these innovative seal units make it quicker, cheaper 
and safer to assess pipelines for corrosion.

The Company is utilising all the R&D efforts described above, to create 
the Grid modernisation plans for all jurisdictions.

Unresolved SEC staff comments
There are no unresolved SEC staff comments required to be reported.

•  We continued to progress our Smart City REV demonstration project 
in partnership with the city of Schenectady. Phase 1, which involves 
procurement, deployment and initial operation of all selected 
technologies, has progressed beyond 90% completion. Now we are 
collaborating on the establishment and assessment of functional 
performance characteristics, including feedback from city stakeholders 
to evaluate the public acceptance and the overall value proposition. 
Phase 2 of the project is currently in the technology procurement 
phase, which will then be deployed in the remaining areas of the city. 

•  National Grid is heavily engaged on several programmes, including 
bulk system renewables, DERs integration, planning and asset 
management, energy storage, asset management for transmission 
and distribution, system automation and integrating emerging 
technologies. 

•  To proactively monitor environmental conditions within underground 
structures (manholes) we have piloted the installation of manhole 
monitoring technology produced by CNIguard. Underground 
infrastructure can be susceptible to the accumulation of water, debris 
and salt that can result in the degradation of assets. This can result in 
failure of the assets thereby increasing the operation and loading on 
parallel equipment. National Grid has installed nine units in Providence, 
Rhode Island and 11 in Brockton, Massachusetts and will be installing 
12 in Albany, NY, 12 in Brockton, Massachusetts and 12 
in Providence, Rhode Island in the second quarter of 2020.

•  National Grid is preparing to demonstrate online monitoring technology 
at transmission substations and lines in our New England service area. 
These technologies will allow the Company to utilise the capacity of 
lines and transformers more efficiently and focus maintenance efforts 
on the assets which are at the greatest risk.

•  Over the next 10 years we will be deploying up to 170 digital 

substations in New England and New York as we transition to fully 
digital substations on our transmission network, which will utilise the 
IEC 61850 communications standard. The digital substation reduces 
construction and operation costs, engineering and construction 
time, increases system flexibility, and helps facilitate the large-scale 
incorporation of renewable power.

US gas:
•  While partnering with a robotics company and another utility, we have 
been developing and testing new technology to locate inadvertent 
sewer cross bores created when using some trenchless technology. 
This technology is deployed in our gas main immediately after 
installation, prior to the introduction of natural gas. It differs from the 
current process, which requires us to gain access to the municipal 
sewer system. Deployment will reduce the risk and cost associated 
with sewer cross bores. We constructed a functional sewer system 
covering five hectares at one of our facilities to test the accuracy of 
the technology. We purposefully created cross bores in the system 
at several points to determine if the technology could locate them. 
The technology found all the cross bores with no false negatives. We 
are currently transitioning the technology to the field for live testing.
•  We have been working with a Canadian valve manufacturer to develop 
a service isolation valve to locally and remotely isolate a gas service. 
The application has become necessary due to recent industry 
incidents in the US. The valve has passed all industry and National 
Grid required testing and can be installed on service lines up to 11 bar 
of pressure. The valve can take a switched signal from any source 
and locally isolate the gas service. Signals include flood, fire, seismic, 
under-pressurisation, over-pressurisation and methane. The valve 
can also be closed via a wireless signal from National Grid. We are 
currently building 75 units to be deployed in the New York State 
service territory. We are in conversations with our regulators to 
expand the testing to 1,000 units as a solution to hurricane Sandy 
flooding issues.

•  To enhance the functionality of the service isolation valve, we have 

been working to develop and deploy enhanced residential methane 
detectors (RMDs). With the deployment of the 75 service isolation 
valves, we are installing European manufactured RMDs that are 
powered by 120 V and hard wired to the valve control. We are 
working with several manufacturers on enhancements: first to 
power the unit with long-term batteries (current technology limits 
battery life to three years); and second, to introduce wireless 
communication to the valve controller (as current technology 
requires wiring from the RMD to the isolation valve). We are 
developing an RMD with communications technology that would 
allow installation of the RMD in remote locations in residential flats, 
and installation of the RMD in locations where gas is being used 
to signal if gas escapes.

Alternative performance measures/non-IFRS reconciliations
Within the Annual Report, a number of financial measures are presented. These measures have been categorised as alternative performance 
measures (APMs), as per the European Securities and Markets Authority (ESMA) guidelines and the Securities and Exchange Commission (SEC) 
conditions for use of non-GAAP financial measures. 

An APM is a financial measure of historical or future financial performance, financial position, or cash flows, other than a financial measure defined 
under IFRS. The Group uses a range of these measures to provide a better understanding of its underlying performance. APMs are reconciled to the 
most directly comparable IFRS financial measure where practicable. 

The Group has defined the following financial measures as APMs derived from IFRS: net revenue, the various adjusted operating profit, earnings and 
earnings per share metrics detailed in the ‘adjusted profit measures’ section below, net debt, capital investment, funds from operations (FFO), FFO 
interest cover and retained cash flow (RCF)/adjusted net debt. For each of these we present a reconciliation to the most directly comparable IFRS 
measure. 

We also have a number of APMs derived from regulatory measures which have no basis under IFRS; we call these Regulatory Performance 
Measures (RPMs). They comprise: Group Return on Equity (RoE), UK and US regulatory RoE, regulated asset base, regulated financial performance, 
regulatory gearing, asset growth, Value Added, including Value Added per share and Value Growth. These measures include the inputs used by 
utility regulators to set the allowed revenues for many of our businesses. 

We use RPMs to monitor progress against our regulatory agreements and certain aspects of our strategic objectives. Further, targets for certain  
of these performance measures are included in the Company’s Annual Performance Plan (APP) and Long Term Performance Plan (LTPP) and 
contribute to how we reward our employees. As such, we believe that they provide close correlation to the economic value we generate for our 
shareholders and are therefore important supplemental measures for our shareholders to understand the performance  
of the business and to ensure a complete understanding of Group performance. 

As the starting point for our RPMs is not IFRS, and these measures are not governed by IFRS, we are unable to provide meaningful reconciliations  
to any directly comparable IFRS measures, as differences between IFRS and the regulatory recognition rules applied have built up over many years. 
Instead, for each of these we present an explanation of how the measure has been determined and why it is important, and an overview as to why it 
would not be meaningful to provide a reconciliation to IFRS. 

Alternative performance measures
Net revenue
Net revenue is revenue less pass-through costs, such as UK system balancing costs, gas and electricity commodity costs in the US and, prior to the 
adoption of IFRS 15, payments to other UK network owners. Pass-through costs are fully recoverable from our customers and are recovered through 
separate charges that are designed to recover those costs with no profit. Any over- or under-recovery of these costs is returned to, or recovered 
from, our customers.

Adjusted profit measures
In considering the financial performance of our business and segments, we use various adjusted profit measures in order to aid comparability  
of results year-on-year. 

The various measures are presented on pages 28 – 37 and reconciled below. 

Adjusted results, also referred to as Headline results – these exclude the impact of exceptional items and remeasurements that are treated as 
discrete transactions under IFRS and can accordingly be classified as such. This is a measure used by management that forms part of the incentive 
target set annually for remunerating certain Executive Directors, and further details of these items are included in Note 5 to the financial statements. 

Underlying results – further adapts our adjusted results to take account of volumetric and other revenue timing differences arising due to the  
in-year difference between allowed and collected revenues, including revenue incentives, as governed by our rate plans in the US or regulatory price 
controls in the UK (but excluding totex-related allowances and adjustments). For 2019/20, as highlighted on page 241, our underlying results exclude  
£147 million (2018/19: £108 million) of timing differences. We have not excluded major storm costs this year as costs were below our $100 million 
storm cost timing threshold (2018/19: £93 million). We expect to recover major storm costs incurred through regulatory mechanisms in the US.  

Constant currency – the adjusted profit measures are also shown on a constant currency basis to show the year-on-year comparisons excluding any 
impact of foreign currency movements.

Timing and regulated revenue adjustments
As described on pages 219 – 226, our allowed revenues are set in accordance with our regulatory price controls or rate plans. We calculate 
the tariffs we charge our customers based on the estimated volume of energy we expect will be delivered during the coming period. The actual 
volumes delivered will differ from the estimate. Therefore, our total actual revenue will be different from our total allowed revenue. These differences 
are commonly referred to as timing differences. 

If we collect more than the allowed revenue, the balance must be returned to customers in subsequent periods, and if we collect less than the 
allowed level of revenue, we may recover the balance from customers in subsequent periods. In the US, a substantial portion of our costs are 
pass-through costs (including commodity and energy-efficiency costs) and are fully recoverable from our customers. Timing differences between 
costs of this type being incurred and their recovery through revenue are also included in timing. The amounts calculated as timing differences are 
estimates and subject to change until the variables that determine allowed revenue are final. 

Our continuing operating profit for the year includes a total estimated in-year under-collection of £147 million (2018/19: £108 million over-collection). 
Our closing balance at 31 March 2020 was £256 million over-recovered. In the UK, there was a cumulative over-recovery of £24 million at 31 March 
2020 (2019: under-recovery of £59 million). In the US, cumulative timing over-recoveries at 31 March 2020 were £240 million (2019: £466 million 
over-recovery). 

The total estimated in-year over- or under-collection excludes opening balance adjustments related to estimates or finalisation of balances as part  
of regulatory submissions.  

In addition to the timing adjustments described above, as part of the RIIO price controls in the UK, outperformance against allowances as a result  
of the totex incentive mechanism, together with changes in output-related allowances included in the original price control, will almost always be 
adjusted in future revenue recoveries, typically starting in two years’ time. We are also recovering revenues in relation to certain costs incurred  
(for example pension contributions made) in prior years. 

Our current IFRS revenues and earnings include these amounts that relate to certain costs incurred in prior years or that will need to be repaid 
or recovered in future periods. Such adjustments will form an important part of the continuing difference between reported IFRS results and 
underlying economic performance based on our regulatory obligations. 

For our UK Regulated businesses as a whole, timing and regulated revenue adjustments totalled a recovery of £92 million in the year (2018/19:  
£115 million return). In the US, accumulated regulatory entitlements cover a range of different areas, with the most significant being environmental 
remediation and pension assets, as well as deferred storm costs. 

All regulatory entitlements are recoverable (or repayable) over different periods, which are agreed with the regulators to match the expected payment 
profile for the liabilities.

Capital investment
‘Capital investment’ or ‘investment’ refer to additions to property, plant and equipment and intangible assets, and contributions to joint ventures and 
associates, other than the St William Homes LLP joint venture during the period. We also include the Group’s investments by National Grid Partners 
during the period, which are classified for IFRS purposes as non-current financial assets in the Group’s consolidated statement of financial position. 

Investments made to our St William Homes LLP arrangement are excluded based on the nature of this joint venture arrangement. We typically 
contribute property assets to the joint venture in exchange for cash and accordingly do not consider these transactions to be in the nature of 
capital investment.

Retained cash flow/adjusted net debt 
RCF/adjusted net debt is one of two credit metrics that we monitor in order to ensure the Group is generating sufficient cash to service its debts, 
consistent with maintaining a strong investment-grade credit rating. We calculated RCF/adjusted net debt applying the methodology used by 
Moody’s, as this is one of the most constrained calculations of credit worthiness. The net debt denominator includes adjustments to take account  
of the equity component of hybrid debt.

Regulatory Performance Measures 
Regulated financial performance – UK
Regulatory financial performance is a pre-interest and tax measure, starting at segmental operating profit and making adjustments (such as the 
elimination of all pass-through items included in revenue allowances and timing) to approximate regulatory profit for the UK regulated activities.  
This measure provides a bridge for investors between a well-understood and comparable IFRS starting point and through the key adjustments 
required to approximate regulatory profit. This measure also provides the foundation to calculate Group RoE. 

For the reasons noted above, the table below shows the principal differences between the IFRS operating profit and the regulated financial 
performance, but is not a formal reconciliation to an equivalent IFRS measure.

US timing, major storms and movement in UK regulatory ‘IOUs’ – Revenue related to performance in one year may be recovered in later 
years. Revenue may be recovered in one year but be required to be returned to customers in future years. In the UK, this is calculated as the 
movement in other regulated assets and liabilities. 

Performance RAV – UK performance efficiencies are in-part remunerated by the creation of additional RAV which is expected to result in future 
earnings under regulatory arrangements. This is calculated as in-year totex outperformance multiplied by the appropriate regulatory capitalisation 
ratio and multiplied by the retained company incentive sharing ratio. 

Pension adjustment – Cash payments against pension deficits in the UK are recoverable under regulatory contracts. In US Regulated operations, 
US GAAP pension charges are generally recoverable through rates. Revenue recoveries are recognised under IFRS but payments are not charged 
against IFRS operating profits in the year. In the UK, this is calculated as cash payments against the regulatory proportion of pension deficits in the 
UK regulated business, whereas in the US, it is the difference between IFRS and US GAAP pension charges. 

3% RAV indexation – Future UK revenues are expected to be set using an asset base adjusted for inflation. This is calculated as UK RAV multiplied 
by 3% (long-run RPI inflation assumption). 

UK deferred taxation adjustment – Future UK revenues are expected to recover cash taxation cost including the unwinding of deferred taxation 
balances created in the current year. This is the difference between: (a) IFRS underlying EBITDA less other regulatory adjustments; and (b) IFRS 
underlying EBITDA less other regulatory adjustments less current taxation (adjusted for interest tax shield) then grossed up at full UK statutory  
tax rate. 

Regulatory depreciation – US and UK regulated revenues include allowance for a return of regulatory capital in accordance with regulatory 
assumed asset lives. This return does not form part of regulatory profit. 

Fast/slow money adjustment – The regulatory remuneration of costs incurred is split between in-year revenue allowances and the creation of 
additional RAV. This does not align with the classification of costs as operating costs and fixed asset additions under IFRS accounting principles. 
This is calculated as the difference between IFRS classification of costs as operating costs or fixed asset additions and the regulatory classification.

Regulated asset base
The regulated asset base is a regulatory construct, based on predetermined principles not based on IFRS. It effectively represents the invested 
capital on which we are authorised to earn a cash return. By investing efficiently in our networks, we add to our regulated asset base over the long 
term, and this in turn contributes to delivering shareholder value. Our regulated asset base is comprised of our regulatory asset value in the UK, plus 
our rate base in the US. 

Maintaining efficient investment in our regulated asset base ensures we are well positioned to provide consistently high levels of service to our 
customers and increases our revenue allowances in future years. While we have no specific target, our overall aim is to achieve between 5% and  
7% growth in regulated asset base each year through continued investment in our networks in both the UK and US. 

In the UK, the way in which our transactions impact RAV is driven by principles set out by Ofgem. In a number of key areas these principles differ 
from the requirements of IFRS, including areas such as additions and the basis for depreciation. Further, our UK RAV is adjusted annually for inflation. 
RAV in each of our retained UK businesses has evolved over the period since privatisation in 1990, and as a result, historical differences between  
the initial determination of RAV and balances reported under UK GAAP at that time still persist. Due to the above, substantial differences exist in  
the measurement bases between RAV and an IFRS balance metric, and therefore, it is not possible to provide a meaningful reconciliation between 
the two. 

In the US, rate base is a regulatory measure determined for each of our main US operating companies. It represents the value of property and other 
assets or liabilities on which we are permitted to earn a rate of return, as set out by the regulatory authorities for each jurisdiction. The calculations  
are based on the applicable regulatory agreements for each jurisdiction and include the allowable elements of assets and liabilities from our US 
companies. For this reason, it is not practical to provide a meaningful reconciliation from the US rate base to an equivalent IFRS measure. However, 
we include the calculation below. 

‘Total Regulated and other balances’ includes the under or over-recovery of revenues that National Grid’s UK regulated businesses target to collect  
in any year, which are based on the regulator’s forecasts for that year. Under the UK price control arrangements, revenues will be adjusted in future 
years to take account of actual levels of collected revenue, costs and outputs delivered when they differ from those regulatory forecasts. In the US, 
other regulatory assets and liabilities include regulatory assets and liabilities which are not included in the definition of rate base, including working 
capital where appropriate.  

The investment in ‘NGV and other businesses’ includes net assets excluding pensions, tax and items related to the UK Gas Distribution sale.

pack process in 2019, and finalisation of US balances. 

US rate base and Total Regulated and other balances for 31 March 2019 have been restated in the table above at constant currency. At actual 
currency the values were £17.6 billion and £19.5 billion respectively.

Other business assets and other balances for NGV and Other businesses for 31 March 2019 have been restated in the table above for the impact  
of IFRS 16 leases, constant currency and to exclude out 39% share of our investment in Quadgas. At actual currency excluding IFRS 16 leases  
the values were £2.8 billion and £2.7 billion respectively.

Group RoE
Group RoE provides investors with a view of the performance of the Group as a whole compared with the amounts invested by the Group in 
assets attributable to equity shareholders. It is the ratio of our regulatory financial performance to our measure of equity investment in assets.  
It therefore reflects the regulated activities as well as the contribution from our non-regulated businesses together with joint ventures and 
non-controlling interests. 
We use Group RoE to measure our performance in generating value for our shareholders, and targets for Group RoE are included in the incentive 
mechanisms for executive remuneration within both the APP and LTPP schemes. 
Group RoE is underpinned by our regulated asset base. For the reasons noted above, no reconciliation to IFRS has been presented, as we do  
not believe it would be practical. However, we do include the calculations below. 
Calculation: Regulatory financial performance including a long-run assumption of 3% RPI inflation, less adjusted interest and adjusted taxation 
divided by equity investment in assets: 
•  adjusted interest removes interest on pensions, capitalised interest in regulated operations and unwind of discount rate on provisions; 
•  adjusted taxation adjusts the Group taxation charge for differences between IFRS profit before tax and regulated financial performance less 

adjusted interest; and 

•  equity investment in assets is calculated as the total opening UK regulatory asset value, the total opening US rate base plus goodwill plus 
opening net book value of National Grid Ventures and Other activities and our share of joint ventures and associates, minus opening net  
debt as reported under IFRS restated to the weighted average £/$ exchange rate for the year.

UK regulated RoE
UK regulated RoEs are a measure of how the businesses are performing against the assumptions used by our UK regulator. These returns are 
calculated using the assumption that the businesses are financed in line with the regulatory adjudicated capital structure, at the cost of debt 
assumed by the regulator, and that RPI inflation is equal to a long-run assumption of 3%. They are calculated by dividing elements of out/under-
performance versus the regulatory contract (i.e., regulated financial performance disclosed above) by the average equity RAV in line with the 
regulatory assumed capital structure and adding to the base allowed RoE. 

This is an important measure of UK regulated business performance, and our operational strategy continues to focus on this metric. This measure 
can be used to determine how we are performing under the RIIO framework and also helps investors to compare our performance with similarly 
regulated UK entities. Reflecting the importance of this metric, it is also a key component of the APP scheme. 

The UK RoE is underpinned by the UK RAV. For the reasons noted above, no reconciliation to IFRS has been presented, as we do not believe it 
would be practical. 

US regulated RoE
US regulated RoE is a measure of how a business is performing against the assumptions used by the US regulators. This US operational return 
measure is calculated using the assumption that the businesses are financed in line with the regulatory adjudicated capital structure and allowed 
cost of debt. The returns are divided by the average rate base (or where a reported rate base is not available, an estimate based on rate base 
calculations used in previous rate filings) multiplied by the adjudicated equity portion in the regulatory adjudicated capital structure. 

This is an important measure of our US regulated business performance, and our operational strategy continues to focus on this metric. This 
measure can be used to determine how we are performing and also helps investors compare our performance with similarly regulated US entities. 
Reflecting the importance of this metric, it is also a key component of the APP scheme. 

The US return is based on a calculation which gives proportionately more weighting to those jurisdictions which have a greater rate base. For the 
reasons noted above, no reconciliation to IFRS for the RoE measure has been presented, as we do not believe it would be practical to reconcile  
our IFRS balance sheet to the equity base. 

The table below shows the principal differences between the IFRS result of the US Regulated segment, and the ‘return’ used to derive the US RoE.  
In outlining these differences, we also include the result for the US regulated Operating Companies (OpCo) entities aggregated under US GAAP.  

In respect of 2018/19 and 2017/18, this measure is the aggregate operating profit of our US OpCo entities’ publicly available financial statements 
prepared under US GAAP. For 2019/20, this measure represents our current estimate, since local financial statements have yet to be prepared.

Value Added and Value Added per share and Value Growth
Value Added is a measure that reflects the value to shareholders of our cash dividend and the growth in National Grid’s regulated and non-regulated 
assets (as measured in our regulated asset base, for regulated entities), and corresponding growth in net debt. It is a key metric used to measure our 
performance and underpins our approach to sustainable decision-making and long-term management incentive arrangements. 

Value Added is derived using our regulated asset base and, as such, it is not practical to provide a meaningful reconciliation from this measure to  
an equivalent IFRS measure due to the reasons set out for our regulated asset base. However, the calculation is set out in the Financial review on page 
32. Value Added per share is calculated by dividing Value Added by the weighted average number of shares (3,461 million) set out in note 8 on page 145.

Value Growth of 10.4% (2018/19: 11.5%) is derived from Value Added by adjusting Value Added to normalise for a 3% long-run RPI inflation rate.  
In 2019/20, the numerator for Value Growth was £2,068 million (2018/19: £2,166 million). The denominator is Group equity as used in the Group  
RoE calculation, adjusted for foreign exchange movements.

Asset growth
Asset growth is the annual percentage increase in our RAV and rate base and other business balances (including the assets of NGV and NGP) 
calculated at constant currency.

Regulatory gearing
Regulatory gearing is a measure of how much of our investment in RAV and rate base and other elements of our invested capital (including our 
investments in NGV, UK property and other assets and US other assets) is funded through debt. Comparative amounts as at March 2019 are 
presented at historical exchange rates and have not been restated for opening balance adjustments.

National Grid plc Annual Report and Accounts 2019/20Commentary on consolidated financial statements  
for the year ended 31 March 2019

Additional Information 

In compliance with SEC rules, we present a summarised analysis of movements in the income statement and an analysis of movements in adjusted 
operating profit (for the continuing group) by operating segment. This should be read in conjunction with the 31 March 2020 financial review 
included on pages 28 – 37.

Adjusted earnings and EPS from continuing operations 
Adjusted earnings and EPS, which exclude exceptional items and 
remeasurements, are provided to reflect the Group’s results on 
a ‘business performance’ basis, described further in note 5.  
See page 242 for a reconciliation of adjusted basic EPS to EPS.

The above earnings performance translated into an increase in adjusted 
EPS in 2018/19 of 3.7p (7%).

Exchange rates 
Our financial results are reported in sterling. Transactions for our US 
operations are denominated in dollars, so the related amounts that are 
reported in sterling depend on the dollar to sterling exchange rate. The 
table below shows the average and closing exchange rates of sterling  
to US dollars.

The movement in foreign exchange during 2018/19 has resulted in  
a £355 million increase in revenue, a £62 million increase in adjusted 
operating profit and a £63 million increase in operating profit.

The movement in foreign exchange during 2018/19 has resulted in  
a £355 million increase in revenue, a £62 million increase in adjusted 
operating profit and a £63 million increase in operating profit.

Analysis of the adjusted operating profit by segment for the 
year ended 31 March 2019 
UK Electricity Transmission
For the year ended 31 March 2019, revenue in the UK Electricity 
Transmission segment decreased by £803 million to £3,351 million,  
and adjusted operating profit decreased by £26 million to £1,015 
million. Revenue was significantly impacted by the adoption of IFRS 15, 
with revenues collected from customers but passed on to the Scottish 
and Offshore transmission operators are now excluded from both 
revenue and operating costs, compared to £1,027 million in 2017/18. 
Excluding pass-through costs, net revenue was £43 million higher, 
reflecting higher baser allowances including the impact of inflation and 
increased incentives income, partially offset by the return of outstanding 
timing balances along with higher adjustments this year to return the 
benefits of efficiencies and lower required outputs to customers. 
Regulated controllable costs were £11 million higher, reflecting inflation, 
increased headcount and workload, and initiative spend. Depreciation 
and amortisation was £18 million higher, reflecting the continued capital 
investment programme. Other costs were £41 million higher, principally 
relating to provision against income recognised on early termination of 
connections. 

Capital expenditure decreased by £74 million compared with 2016/17 to 
£925 million reflecting reduced activity on Western Link and completion 
of the London Power Tunnels project. 

Analysis of the income statement for the year ended  
31 March 2019 
Revenue
Revenue for the year ended 31 March 2019 decreased by £317 million  
to £14,933 million. This decrease was driven by lower revenues in our 
UK Electricity Transmission business and in our UK Gas Transmission 
business, partially offset by higher revenues in our US Regulated and 
NGV and Other businesses. US Regulated revenues were £574 million 
higher year-on-year, principally due to the impact of new rate plans, the 
benefit of foreign exchange and recovery of prior year timing under-
collections, partially offset by the collection of lower tax allowances and 
the impact of IFRS 15. UK Electricity Transmission revenues decreased 
by £803 million, (related to IFRS 15, which reduced both revenues and 
costs by £1.0 billion), partly offset by higher BSIS pass-through costs 
and return of prior year timing over-collections. UK Gas Transmission 
revenues were £195 million lower, driven by the return of allowances 
related to Avonmouth. Revenue from NGV and Other businesses 
increased by £100 million, primarily driven by sales in our Commercial 
Property business. 

Operating costs
Operating costs for the year ended 31 March 2019 of £12,063 million 
were £306 million higher than the prior year. This increase in  
costs included a £608 million increase in exceptional items and 
remeasurements, which is discussed below. Excluding exceptional  
items and remeasurements, operating costs were £302 million lower, 
driven by the impact of IFRS 15, which reduced costs (and related 
revenues) for payments to other network owners by £1,043 million, 
partially offset by higher pass-through costs, increased rates and 
property taxes, higher depreciation as a result of continued asset 
investment and the impact of movement in exchange rates.

Net finance costs
For the year ended 31 March 2019, net finance costs before exceptional 
items and remeasurements were £8 million lower than 2017/18 at £993 
million, mainly as a result of the impact of the stronger US dollar and 
lower pension net interest expense due to lower pension net liabilities 
and other interest gains, partially offset lower gains on the sale of 
financial assets and the impact of higher UK RPI inflation. Net finance 
costs in 2018/19 included remeasurement losses of £76 million on 
derivative financial instruments used to hedge our borrowings, 
compared to £119 million of remeasurement gains in 2017/18. 

Tax 
The tax charge on profits before exceptional items and remeasurements 
of £488 million was £96 million lower than 2017/18. This reduction was 
primarily due to a full year’s benefit in 2018/19 from the Tax Cut & Jobs 
Act which reduced the US corporate tax rate from 35% to 21% with 
effect from 1 January 2018. 

Exceptional items and remeasurements 
Operating costs for the year ended 31 March 2019 included £283 million 
of costs arising from the workforce contingency plan related to the 
Massachusetts Gas labour dispute, £204 million of restructuring charges 
in our UK and US businesses and £137 million related to the impairment 
of nuclear connection development costs following the cancellation of 
the NuGen and Horizon projects. These were partially offset by a net 
£52 million gain on remeasurement of commodity contracts. In the 
previous year, operating costs included a £26 million gain on settlement 
of outstanding balances related to the LIPA Management Services 
Agreement, together with a net £10 million gain on remeasurement of 
commodity contracts.

Finance costs for the year ended 31 March 2019 included a net loss  
of £76 million on financial remeasurements of derivative financial 
instruments used to hedge our borrowings, compared to a gain of  
£119 million on financial remeasurements in 2017/18.

Share of post-tax results of joint ventures and associates before 
exceptional items for the year ended 31 March 2019 of £40 million 
was £4 million lower, principally due to higher costs in St William.

National Grid plc Annual Report and Accounts 2019/20Additional Information Additional Information | Other unaudited financial information

UK Gas Transmission 
Revenue in the UK Gas Transmission segment decreased by  
£195 million to £896 million, and adjusted operating profit decreased  
by £184 million to £303 million. 

After deducting pass-through costs, net revenue was £165 million lower 
than 2017/18, reflecting the refund of revenues previously received in 
respect of the proposed Avonmouth pipeline project that is no longer 
required. Regulated controllable costs were £2 million lower than 
2017/18, with efficiency savings offsetting the higher IT run-the-business 
costs and the impact of inflation. Pension costs were £9 million higher 
mainly related to the Guaranteed Minimum Pension equalisation ruling. 
Depreciation and amortisation costs were £13 million lower following a 
detailed review of asset lives in the year. Other operating costs were  
£25 million higher than 2017/18, as a result of the release of unused 
provisions in the prior year. 

Capital expenditure marginally decreased to £308 million, £2 million 
lower than last year. 

US Regulated 
Revenue in our US Regulated business increased by £574 million to 
£9,846 million, and adjusted operating profit increased by £26 million 
to £1,724 million. 

The stronger US dollar decreased revenue and operating profit in 
2018/19. Excluding the impact of foreign exchange rate movements, 
revenue increased by £202 million. Of this increase, £21 million was due 
to increases in pass-through costs charged on to customers. Excluding 
pass-through costs, net revenue increased by £181 million at constant 
currency, principally reflecting increased revenue allowances under rate 
plans in upstate and downstate New York and in Massachusetts, 
partially offset by the impact of US tax reform (as the billing tariffs now 
reflect lower tax requirements) and the impact of IFRS 15, under which 
customer connection revenues are now recognised over the life of the 
asset rather than on completion of the works. 

We incurred £93 million of major storm costs in 2018/19 through 
a number of heavy winter storms that caused substantial damage to  
our electricity networks, compared to £142 million in 2017/18. Excluding 
these costs and the impact of foreign exchange movements, regulated 
controllable costs increased by £106 million, reflecting workload 
increases agreed with regulators and the impact of inflation. Bad debt 
expense increased by £42 million at constant currency, reflecting higher 
levels of receivables and cash collection studies. Depreciation and 
amortisation was £40 million higher in 2018/19 at constant currency as  
a result of ongoing investment in our networks. Other operating costs 
were £41 million higher at constant currency, due to more expenditure 
on ‘minor’ storms (non-deferrable) and increased cost of removal. 

Capital expenditure in the US Regulated business increased to  
£2,650 million in 2018/19, £226 million more than in 2017/18. At  
constant currency, this represented a £129 million increase in  
investment driven by higher investment in new and replacement 
gas mains and gas business enablement investment, partially  
offset by the impact of the Massachusetts Gas labour dispute. 

NGV and Other
Revenue in NGV and Other increased by £100 million to £876 million, 
and adjusted operating profit increased by £169 million to £400 million. 
This reflects higher revenues and profit on disposal of property sites 
in the UK and lower costs to setting up our new business and the 
absence of the impairment of land value in 2017/18. 

Capital expenditure in NGV and Other was £107 million higher  
than 2017/18 at £438 million, including the increased investment  
in a second French Interconnector and in the North Sea Link 
interconnector to Norway.

It contains the Directors’ Report and Financial Statements, together 
with the independent auditor’s report thereon, as required by the 
Companies Act 2006. The Directors’ Report, comprising pages 1 – 107 
and 216 – 252 has been drawn up in accordance with the requirements 
of English law, and liability in respect thereof is also governed by English 
law. In particular, the liability of the Directors for these reports is solely 
to National Grid.

This document contains certain statements that are neither reported 
financial results nor other historical information. These statements are 
forward-looking statements within the meaning of Section 27A of the 
Securities Act of 1933, as amended, and Section 21E of the Securities 
Exchange Act of 1934, as amended. These statements include 
information with respect to our financial condition, our results of

as ‘aims’, ‘anticipates’, ‘expects’, ‘should’, ‘intends’, ‘plans’, ‘believes’, 
‘outlook’, ‘seeks’, ‘estimates’, ‘targets’, ‘may’, ‘will’, ‘continue’, ‘project’ 
and similar expressions, as well as statements in the future tense, 
identify forward-looking statements. These forward-looking statements 
are not guarantees of our future performance and are subject to 
assumptions, risks and uncertainties that could cause actual future 
results to differ materially from those expressed in or implied by such 
forward-looking statements. Many of these assumptions, risks and 
uncertainties relate to factors that are beyond our ability to control or 
estimate precisely, such as the impact of COVID-19 on our operations, 
our employees, our counterparties, our funding and our regulatory and 
legal obligations, but also more widely in terms of changes in laws or 
regulations, including any arising as a result of the United Kingdom’s exit 
from the European Union; announcements from and decisions by 
governmental bodies or regulators, including proposals relating to the 
RIIO-2 price as well as increased economic uncertainty resulting from 
COVID-19; the timing of construction and delivery by third parties of new 
generation projects requiring connection; breaches of, or changes in, 
environmental, climate change, and health and safety laws or regulations, 
including breaches or other incidents arising from the potentially harmful 
nature of our activities; network failure or interruption, the inability to 
carry out critical non-network operations, and damage to infrastructure, 
due to adverse weather conditions, including the impact of major storms 
as well as the results of climate change, due to counterparties being 
unable to deliver physical commodities, or due to the failure of or 
unauthorised access to or deliberate breaches of our IT systems and 

supporting technology; failure to adequately forecast and respond to 
disruptions in energy supply; performance against regulatory targets and 
standards and against our peers with the aim of delivering stakeholder 
expectations regarding costs and efficiency savings; and customers and 
counterparties (including financial institutions) failing to perform their 
obligations to the Company. Other factors that could cause actual 
results to differ materially from those described in this document include 
fluctuations in exchange rates, interest rates and commodity price 
indices; restrictions and conditions (including filing requirements) in our 
borrowing and debt arrangements, funding costs and access to 
financing; regulatory requirements for us to maintain financial resources 
in certain parts of our business and restrictions on some subsidiaries’ 
transactions, such as paying dividends, lending or levying charges; the 
delayed timing of recoveries and payments in our regulated businesses 
and whether aspects of our activities are contestable; the funding 
requirements and performance of our pension schemes and other 
post-retirement benefit schemes; the failure to attract, develop and 
retain employees with the necessary competencies, including leadership 
and business capabilities, and any significant disputes arising with our 
employees or the breach of laws or regulations by our employees; 
the failure to respond to market developments, including competition 
for onshore transmission; the threats and opportunities presented by 
emerging technology; the failure by the Company to respond to, or 
meet its own commitments as a leader in relation to, climate change 
development activities relating to energy transition, including the 
integration of distributed energy resources; and the need to grow our 
business to deliver our strategy, as well as incorrect or unforeseen 
assumptions or conclusions (including unanticipated costs and liabilities) 
relating to business development activity.

For further details regarding these and other assumptions, risks and 
uncertainties that may affect National Grid, please read the Strategic 
Report and the risk factors on pages 227 – 230 of this document. In 
addition, new factors emerge from time to time and we cannot assess 
the potential impact of any such factor on our activities or the extent to 
which any factor, or combination of factors, may cause actual future 
results to differ materially from those contained in any forward-looking 
statement. Except as may be required by law or regulation, the 
Company undertakes no obligation to update any of its forward-looking 
statements, which speak only as of the date of this document.
