WE’RE WRITING THE NEXT CHAPTER IN OUR 
COMPANY’S 116-YEAR HISTORY – AND I’M CONFIDENT 
THE STORY WILL BE ONE OF THE BEST YET.

Chief Executive Officer

LYNN J. GOOD

Chair, President and 
Chief Executive Officer

Ready for what’s

Dear Shareholder:

Today, the speed and depth of transformation in our industry 
are inspiring. In this environment, our ability to develop new 
solutions provides great opportunities to bring more value to 
our customers and the communities we serve. 

While the pace can feel unrelenting at times – not only for 
us, but for those we serve – we’re embracing this shift with 
conviction and optimism as we reimagine our business. 

In 2019, we met our financial targets through our focus 
on execution, made important progress on our long-term 
strategy and demonstrated agility in how we operate. We also 
announced our new, bold vision for net-zero carbon emissions 
by 2050 – built on a diverse mix of resources, including 
carbon-free nuclear and the expansion of our natural gas and 
renewables portfolios. 

Since our founding, Duke Energy has maintained a proud 
legacy of meeting the changing needs of our customers  
and communities. So as we – the 29,000 employees of  
Duke Energy – work together to write the next chapter in our 
history, I’m confident in our ability to deliver the right results. 
2019 is clear proof that Duke Energy is stronger and better 
prepared to shape our future.

Delivering Results the Right Way

Consistent financial results earn the trust of  
our investors – and in 2019, we delivered on  
our commitments. 

Our adjusted earnings per share (EPS) were $5.06 
for the year – above the midpoint of our original 
guidance range. Strong growth in our electric, 
natural gas and commercial renewables businesses 
remained the financial engine for our company. Our 
cost discipline and flexibility supported our strategy 
as we focused on long-term growth. And 2020 will 
be the 94th consecutive year we will pay quarterly 

cash dividends on our common stock, which we 
increased by 2 percent in 2019.

However, uncertainty in the regulatory environment 
in the Carolinas and the impact of the permitting 
and litigation delays for the Atlantic Coast Pipeline 
(ACP) weighed on our stock in 2019. Our total 
shareholder return of 10.3 percent underperformed 
both the Philadelphia Utility Index and the average 
for our regulated peers.

In response, we took aggressive actions.

2 | 2019 DUKE ENERGY ANNUAL REPORT

This February, we 
announced our new 2020 
adjusted EPS target of 
$5.25 and guidance range 
of $5.05 to $5.45. It 
solidifies and extends our 
commitment to deliver a 
long-term growth rate at 4 
to 6 percent through 2024.

In the Carolinas, we reached a 
settlement with the North Carolina 
Department of Environmental 
Quality and several community 
groups on a plan to permanently 
close ash basins in the state. 
The settlement lowers the 
previously estimated closure 
costs by approximately $1.5 
billion, resolves environmental 
litigation, and ensures that people, 
communities and the environment  
are well-protected.

With respect to ACP, we 
continued to advance this project 
despite legal challenges that 
halted major construction. The 
U.S. solicitor general, along with 
18 state attorneys general and 
other stakeholders, joined our 
appeal to the U.S. Supreme Court 
on the project’s ability to cross the 
Appalachian Trail. The Supreme 
Court heard oral arguments this 
past February and is expected to 
issue its ruling in second quarter 
of 2020. We believe the law and 
facts remain on our side as we 
move toward a final resolution  
to restart construction later in  
the year.

We also took steps to strengthen 
our balance sheet – which is 
vital to financing our growth 
strategy while providing flexibility 
to maintain our credit profile. In 
November, we priced $2.5 billion 
in incremental common equity 
that will settle in December  
2020. We also issued $2  
billion in preferred stock in 2019.  

In addition, we closed our minority 
stake sale of our Commercial 
Renewables portfolio to John 
Hancock and issued additional 
green bonds in North Carolina and 
Florida – bringing our total clean 
energy offerings to $2.3 billion 
since 2018.

Importantly, ratings agencies 
acknowledged our efforts.  
In November, S&P resolved  
its negative outlook following  
the $2.5 billion common  
equity offering.

This February, we announced our 
new 2020 adjusted EPS target 
of $5.25 and guidance range 
of $5.05 to $5.45. It solidifies 
and extends our commitment to 
deliver a long-term growth rate 
at 4 to 6 percent through 2024. 
And because of growing demand 
for infrastructure investments, 
we increased our capital plan by 
12 percent to $56 billion – with 
more than 90 percent to be spent 
in our regulated electric and 
gas businesses, driving strong 
earnings base growth.

Our results in 2019 show that 
the foundation of our business is 
strong. With important legal and 
regulatory decisions approaching 
in 2020, we are committed to 
producing outstanding operating 
results for our customers and 
investors while delivering growth 
in earnings and dividends in 
a low-risk, predictable and 
transparent way. That’s our 
promise to you.

Executing Our Strategy

Our industry is in a period of transformation, and 
our strategy will continue to guide how we invest 
to meet the changing needs of our customers 
and communities while maintaining flexibility and 
creating shareholder value. Our commitment to 
deliver outstanding customer service and value by 
investing in our grid, cleaner energy and natural gas 
infrastructure is moving us forward. 

Transforming the Customer Experience

investments to meet the needs of our customers, 
striving to provide the personalized service they  
expect today.

We improved how we communicate with customers 
on their terms, including proactive payment 
confirmation, energy usage alerts, and timely safety 
and outage information during storms. In addition, 
we launched an interactive outage map. Now, 
customers can get updates in real time and better 
understand restoration efforts. 

Our strategy begins and ends with the customer. 
This past year, we continued to direct our 

We made it easier for customers to access their 
payment history and usage data, and pay their bill

We also earned a 25 
percent increase on 
our internal customer 
satisfaction metrics.

online – including the launch of 
our new mobile app. And we 
made progress upgrading our 
customer information system. 
This platform, called Customer 
Connect, will give us the ability to 
provide enhanced communications 
and solutions. This includes an 
improved bill format for customers 
in the first half of 2020. Customer 
Connect remains on track to be 
fully implemented by 2022.

Yet, we are not relying solely 
on technology to create better 
relationships. We look for every 
opportunity to engage face to 
face with customers through 
community events, town halls 
and pop-up office locations. 
In addition, our employees 
review customer feedback each 
month to identify improvement 
opportunities and develop local 
plans for our communities. 

Our focus on customers shows in 
our customer satisfaction metrics. 
In 2019, we saw improvement 
across almost all our territories

relationships and giving them a 
best-in-class experience. 

Generating  
Cleaner Energy

Around the world, countries, 
companies and communities 
are adding their voice to the 
conversation on how to achieve a 
lower-carbon future. 

5 | 2019 DUKE ENERGY ANNUAL REPORT

I’m proud to say we have long 
been an important contributor 
to that discussion. Since 2005, 
we have reduced our carbon 
emissions 39 percent, which 
exceeds the goals of the former 
Clean Power Plan and the  
2025 U.S. commitment to the 
Paris Agreement.

Over the past year, we took that 
commitment even further. 

In 2019, we refreshed our climate 
strategy and accelerated our  
goals as we now plan to reduce 
our carbon emissions from 
electricity generation by at least 
50 percent from 2005 levels by 
2030 and to achieve net-zero 
emissions by 2050. 

It will take a thoughtful, 
disciplined approach to attain 
these ambitious goals. We need 
a diverse set of resources – 
including increased investments in 
renewables, storage, natural gas 
and energy efficiency, in addition 
to the retirement of coal plants – 
to achieve our 2030 goal. 

To reach our 2050 target, we 
are advocates for investments 
in research and development 
and new technologies – such as 
enhanced storage, carbon capture, 
advanced nuclear and new, 
carbon-free solutions that don’t 
exist yet at scale.

And we cannot overstate the 
importance of nuclear. In the 
Carolinas, our nuclear plants 
account for nearly half of our 
generation. Currently, we’re 
pursuing subsequent license 
renewal for our entire nuclear fleet. 
This will enable us to operate our 
plants for an additional 20 years. 

We recognize the importance 
of accelerating the path to net-
zero carbon emissions and 
look forward to working with 
stakeholders in each of our states 
to turn these goals into reality. 

As we do, our current investments 
to generate cleaner energy align 
with our goal for 2030 and 
beyond.

We achieved substantial 
completion of our 560-megawatt 
Asheville combined-cycle natural 
gas plant and retired two coal-fired 
units at the site – all part of our 
Western Carolinas Modernization 
project. The Asheville plant is 
our third combined-cycle plant 
to come online in the past two 
years. Natural gas plays an 
important role in lowering our 
carbon emissions and effectively 
integrating renewable  
energy resources. 

Renewables remain a critical part 
of our strategy. We added more 
than 2,500 megawatts of solar 
capacity to our grid over the past 
four years, including significant 
growth in North Carolina that 
helped keep the state second in 
the nation for solar capacity.

In 2019, we were awarded 
approximately 190 megawatts 
of utility-scale solar under North 
Carolina House Bill 589. Most 
of the projects will come online 
by mid-2021. The number of 
customers who installed or 
received a rebate under our $62 
million, multiyear rebate program 
in North Carolina increased 
by nearly 1,700 – bringing the 
total to 3,600 rebates. We also 
launched our Green Source 
Advantage program, helping  
large customers meet their 
sustainability goals. 

6 | 2019 DUKE ENERGY ANNUAL REPORT

In Florida, our Lake Placid and 
Trenton solar power plants 
came online, bringing nearly 
120 megawatts to customers. 
In addition, we announced 
other solar and battery projects, 
continuing our progress to 
add 700 megawatts of solar 
generation through 2022 while 
projecting to more than double  
our solar investments in the state 
by 2028.

Our Commercial Renewables 
business continues to grow as we 
announced approximately 1,500 
megawatts in new projects, which 
will be placed into service by the 
end of 2020. This included our 
largest solar facility to date, the 
150-megawatt North Rosamond 
solar project in California, which 
began operation in June. As well, 
our 200-megawatt Mesteño 
Windpower project in Texas 
began commercial operations 
in December, producing enough 
energy to power about 60,000 
average homes. 

We have been on a successful 
mission for more than a decade  
to lower our carbon emissions.  
For the 14th consecutive year,  
our company was included in 
the Dow Jones Sustainability 
Index, and in 2020, we plan to 
release our second climate report. 
Our work in 2019 continues our 
momentum to ensure a cleaner 
energy future for those we have 
the privilege to serve.

Modernizing the  
Power Grid

With more than 300,000 line 
miles, our transmission and 
distribution network is the 
largest in the nation. It connects 

We prevented more 
than 610,000 extended 
power outages and saved 
customers approximately 
62 million outage minutes.

EV chargers including residential, 
fleet, public transit and highway 
fast charging.

The security of our grid remains 
paramount. In 2019, we 
continued to upgrade equipment 
and install protective devices 
to meet higher standards and 
increase protection against 
physical and cyber security 
threats. This work also helps to 
enable new technologies and 
support renewable solutions. 
We continued our targeted 
undergrounding effort, identifying 
the most outage-prone power 
lines on our system and moving 
those lines underground.

Evolving customer expectations 
demand a modernized grid, and 
our investments are designed 
to meet their changing needs in 
2020 and beyond. 

Expanding Natural  
Gas Infrastructure

Natural gas remains central to  
our transition to a lower-carbon 
future. But delivering the benefits 
to customers will take an 
extensive, resilient natural gas 
transmission and distribution 
network. That’s why we’re making 
significant investments in this 
critical infrastructure. 

To help Piedmont Natural Gas 
better serve its growing customer 
base, we are moving ahead with 
several projects, including the 
construction of our $300 million 
Robeson liquid natural gas (LNG) 
facility in North Carolina. This will 
provide natural gas during peak 
usage days, protecting customers 
against price spikes and volatility. 

commerce and communities 
to affordable, reliable and 
increasingly clean power.  
With the rising demand for 
new technologies, services and 
capabilities, we continued to 
modernize our grid to enhance 
resiliency and support the future 
needs of our customers. 

Smart meters remain a critical link 
to give customers more access 
to information that helps them 
save energy and money. This past 
year, we installed more than 2 
million smart meters, with more 
than 80 percent of our customers 
currently having the benefit of 
this technology. We completed 
deployments in Indiana and the 
western Carolinas and made 
significant progress in the eastern 
Carolinas and Florida. We are on 
track to be fully deployed in all our 
jurisdictions by year-end 2021.

We expanded our self-optimizing 
grid capabilities – allowing the  
grid to automatically detect 
outages and reroute power to 
restore customers faster. As a 
result, in 2019 we prevented  
more than 610,000 extended 
power outages and saved 
customers approximately 62 
million outage minutes. 

Electrification is an important 
part of our strategy and 
contributor to a lower-carbon 
future. We are investing in this 
infrastructure to spur electric 
vehicle (EV) adoption. In Florida, 
we’re installing 530 EV charging 
stations, and in North Carolina, 
we’ve proposed a pilot that would 
support the installation of 2,000 
EV chargers. Across our service 
territories, we plan to support 
the deployment of nearly 7,500

Engaging Stakeholders

To deliver results for our 
customers, we need constructive 
regulatory policy, which requires 
collaboration and strong 
stakeholder support. 

We made progress in 2019 as we 
brought people together – through 
forums, local advisory councils 
and one-on-one meetings – to find 
public policy solutions that allow 
us to better serve customers and 
build the cleaner energy future 
they deserve. We continually seek 
common ground and continue to 
approach these conversations with  
an open mind.

You can see the results of  
our engagement across our  
service areas.

In North Carolina, the passage 
of Senate Bill (SB) 559 
enables the North Carolina 
Utilities Commission (NCUC) 
to approve storm cost 
securitization, allowing utilities 
to issue bonds to finance storm 
recovery. This tool could save 
customers on storm costs and 
support our balance sheet. While 
we were disappointed the bill did 
not include proposed regulatory 
reforms, we’re encouraged they 
will be a part of the broader 
dialogue in the state’s Clean 
Energy Plan stakeholder process 
in 2020.

Florida SB 796 also passed last 
year, authorizing grid resiliency 
investments to protect against 
extreme weather events. The bill 
provides timely rider recovery, 
and we plan to file our first storm 
protection plan in 2020. 

In the Midwest, we received 
approval from the Ohio Power 
Siting Board to construct the 14-
mile Ohio Central Corridor Pipeline 
project. This is the result of a 
multiyear stakeholder process and 
is a milestone for Cincinnati and 
the region as we invest in critical 
infrastructure improvements to 
better serve customers. We will 
begin construction in late 2020. 

In addition, we continue pursuing 
innovative technologies, such 
as renewable natural gas and 
compressed natural gas initiatives. 
We’ve also invested $300 million 
in pipeline integrity projects, 
demonstrating leadership in 
emissions reductions and safety 
improvements. 

As I discussed earlier, the 
ACP project is a necessary 
infrastructure investment, bringing 
low-cost natural gas to eastern 
North Carolina. In addition to the 
appeal to the U.S. Supreme Court, 
we continue to work diligently with 
the U.S. Fish and Wildlife Service 
on the Biological Opinion and 
Incidental Take Statement – two 
of the project’s federal permits 
held up by the Fourth Circuit. We 
expect the permits to be reissued 
by midyear. Taking these timelines 
into account, we are planning for 
mechanical completion of the 
project in late 2021, with full in-
service in the first half of 2022.

We remain committed to 
this project and the benefits 
the expansion of natural gas 
infrastructure brings to  
our customers and the  
Carolinas region.

8 | 2019 DUKE ENERGY ANNUAL REPORT

In 2019, we filed several rate 
cases. Piedmont Natural Gas 
submitted its first base rate case 
in North Carolina since 2013. In 
October, the NCUC approved our 
settlement with the Public Staff 
and industry groups, maintaining 
timely cost recovery mechanisms 
and demonstrating constructive 
regulatory environments. 

In North Carolina, both our 
electric utilities are seeking 
recovery for investments in cleaner 
generation and improvements to 
our infrastructure. And in Indiana, 
we filed our first rate case in  
16 years for investments to 
support that state’s growing 
customer base.

The right outcomes come from 
collaboration, and we’ll continue 
to engage stakeholders to meet 
our customers’ energy needs. 

Turning Change into 
Opportunity 

Our strategy of providing 
outstanding service that our 
customers value rests on 
a foundation of operational 

excellence, stakeholder 
engagement and business 
transformation.

In 2018, we launched our 
Lighthouse initiative – an 
enterprisewide program to 
find new ways to use digital 
capabilities and transform 
how we operate our business 
while delivering cost savings for 
customers. In early 2019, we 
established an Innovation Center 
at Optimist Hall in Charlotte. We 
have nearly 400 people at this 
facility dedicated to developing 
new products and services. In less 
than a year, the team has more 
than 20 applications in the field, 
supporting our customers and 
enabling our workforce.

Early results like these are very 
encouraging. The desire to reap 
the benefits of changing how 
we work is being embraced by 
people throughout our business, 
from frontline supervisors to 
senior leadership. I look forward 
to reporting on our progress in 
the years ahead as we continue 
transforming how we operate our 
business and serve our customers.

Results Built on Operational Excellence 

Our commitment to operational excellence remains 
foundational to our success.

This focus always starts with safety – of our assets, 
our people, our communities and the environment. 
Once again, our employees delivered industry-
leading results in 2019. We reduced the number of 
injuries and environmental events last year – and 
remain focused on making improvements that move 
us toward event-free operations.

Building on our success, our generation fleet 
produced another solid year. Our nuclear fleet – 

the largest regulated fleet in the United States – 
continued providing safe, reliable and carbon-free 
power to our customers in the Carolinas. The fleet’s 
capacity factor was 95.3 percent in 2019 – the 
21st consecutive year our fleet’s capacity factor was 
above 90 percent. 

Our Edwardsport integrated gasification combined-
cycle facility set records for generation and gasifier 
availability. We also made progress on dual-fuel 
projects at our Belews Creek and Marshall steam 
plants, which will allow the plants to use either 
natural gas or coal. 

10 | 2019 DUKE ENERGY ANNUAL REPORT

And our electric distribution 
system performed well in 2019 
– with grid reliability metrics 
improving 15 percent year  
over year.

We also continued our legacy of 
delivering for customers when 
they needed us most. The 2019 
Atlantic hurricane season was the 
fourth consecutive year that we 
have seen above-average storm 
activity. In response to Hurricane 
Dorian – a Category 5 storm 
with an unpredictable path – we 
mobilized nearly 8,000 resources 
in Florida and more than 10,000 
resources in the Carolinas as we 
braced for the storm. While we 
avoided the worst of Dorian, it still 
caused nearly 300,000 outages 
in our service territories.  

Our team’s preparation enabled us 
to restore more than 95 percent 
of the outages within 24 hours.

Our ability to effectively manage 
all facets of storm response is a 
testament to our team’s extensive 
preparation, coordination and 
on-the-ground leadership. Notably 
in 2019, Duke Energy earned 
EEI’s Emergency Recovery Award 
for our power restoration efforts 
after Winter Storm Diego hit in 
December 2018. This recognition 
was our 22nd EEI award since 
1998.

Duke Energy has a tradition  
of safe, reliable operations,  
and 2019 proved that our  
focus on operational excellence 
remains strong.

Our electric distribution 
system performed well – 
with grid reliability metrics 
improving 15 percent year 
over year.

Supporting Our Communities 

The health of our company is intrinsically linked to 
the communities we serve, and it is imperative that 
we give back – creating jobs, fostering innovation 
and providing support. 

Economic development is one of the ways we do 
that – recruiting new companies to invest and create 
jobs in collaboration with state and local economic 
development agencies. In 2019, Duke Energy 
helped attract $7.1 billion in capital investment and 
create over 15,000 jobs. And I’m proud to say that 
for the 15th consecutive year, we were named to 

Site Selection magazine’s annual list of “Top Utilities 
in Economic Development.”

Duke Energy employees remain ambassadors for our 
company and continue our proud tradition of giving. 
In 2019, our employees and retirees volunteered 
over 136,000 hours. They also pledged more 
than $5.2 million to 4,400 organizations through 
the Power of Giving. Now in its second year, this 
campaign gives our employees a powerful platform 
to contribute to the nonprofit of their choice and 
receive a company match from the Duke Energy 

12 | 2019 DUKE ENERGY ANNUAL REPORT

Foundation. With the Foundation 
match, our employees invested 
nearly $10 million into our 
communities.

In addition, our Foundation 
remained active in supporting 
causes and organizations across 
our service territories, donating 
more than $30 million in 2019. 

We provided funding to help 
communities in Florida prepare 
for future weather events and 
to equip Ohio students with the 
skills needed for careers in the 
energy sector. In Indiana and 
North Carolina, we provided grant 
funding to help the fight against 
the opioid epidemic. And we’re 
working with local organizations 
on affordable housing and access 
to medical care in the Carolinas.

It is important for us to help 
address the needs of the 
communities where our customers 
and employees live and work.

Our success in supporting our 
communities requires a more agile 

and diverse workforce. This past 
year, we continued our efforts to 
attract employees who embody 
these tenets. We also invested 
in education and workforce 
development programs – 
including reskilling, upskilling and 
redeployment of existing workers 
– to build a pipeline of skilled 
workers to meet our evolving 
business needs. 

Duke Energy is not alone in  
feeling the impact of change.  
Our communities are feeling  
the same effects – from a 
changing economy to workforce 
demands – and we stand ready  
to support them. 

Our journey continues but I’m 
proud of our progress. We were 
once again listed by Forbes 
as one of America’s Best 
Employers and as one of Fortune’s 
Most Admired Companies, now 
for the third consecutive year. In 
addition, we earned top marks 
in the 2020 Corporate Equality 
Index – highlighting our focus on 
diversity and inclusion.

Our Foundation remained 
active in supporting causes 
and organizations across 
our service territories, 
donating more than  
$30 million.

Ready for What’s Next

As we look ahead to the energy landscape of the future,  
it’s clear that markets and technologies will continue to 
change. Laws and regulations will evolve. And the expectations 
of our customers and communities will only increase in the 
years ahead. 

We are confident in our ability to shape that future because  
we have adapted and changed for more than a century.

Every era has its challenges and, once again, our workforce 
continues to rise to the occasion. In 2019, we made significant 
progress executing our strategy and transforming our business. 
Our employees’ dedication to our customers and continuous 
improvement is what produced the results we are so proud of  
as a company.

As we look to the next decade, our focus remains on  
execution – because that is what will distinguish us over the 
long term. The strategy is clear: We’re transforming for our 
customers and investing in cleaner energy, the grid and the 
natural gas infrastructure needed to bring more value to  
them. We’re adapting our business, becoming more efficient, 
more competitive and better prepared to meet tomorrow’s 
energy needs.

To our shareholders, thank you for your continued investment 
in Duke Energy. We’re writing the next chapter in our 
company’s 116-year history – and I’m confident the story  
will be one of the best yet.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING INFORMATION

This document includes forward-looking statements within the meaning of Section 27A of 

the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Forward-looking 
statements are based on management’s beliefs and assumptions and can often be identified by 
terms and phrases that include “anticipate,” “believe,” “intend,” “estimate,” “expect,” “continue,” 
“should,” “could,” “may,” “plan,” “project,” “predict,” “will,” “potential,” “forecast,” “target,” 
“guidance,” “outlook” or other similar terminology. Various factors may cause actual results 
to be materially different than the suggested outcomes within forward-looking statements; 
accordingly, there is no assurance that such results will be realized. These factors include, but 
are not limited to:

• State, federal and foreign legislative and regulatory initiatives, including costs of 

compliance with existing and future environmental requirements, including those related 
to climate change, as well as rulings that affect cost and investment recovery or have an 
impact on rate structures or market prices;

• The extent and timing of costs and liabilities to comply with federal and state laws, 

regulations and legal requirements related to coal ash remediation, including amounts 
for required closure of certain ash impoundments, are uncertain and difficult to estimate;

• The ability to recover eligible costs, including amounts associated with coal ash 

impoundment retirement obligations and costs related to significant weather events, 
and to earn an adequate return on investment through rate case proceedings and the 
regulatory process;

• The costs of decommissioning nuclear facilities could prove to be more extensive than 

amounts estimated and all costs may not be fully recoverable through the regulatory process;

• Costs and effects of legal and administrative proceedings, settlements, investigations 

and claims;

• Industrial, commercial and residential growth or decline in service territories or customer 

bases resulting from sustained downturns of the economy and the economic health 
of our service territories or variations in customer usage patterns, including energy 
efficiency efforts and use of alternative energy sources, such as self-generation and 
distributed generation technologies;

• Federal and state regulations, laws and other efforts designed to promote and expand 
the use of energy efficiency measures and distributed generation technologies, such 
as private solar and battery storage, in Duke Energy service territories could result in 
customers leaving the electric distribution system, excess generation resources as well 
as stranded costs;

• Advancements in technology;
• Additional competition in electric and natural gas markets and continued industry consolidation;
• The influence of weather and other natural phenomena on operations, including the 
economic, operational and other effects of severe storms, hurricanes, droughts, 
earthquakes and tornadoes, including extreme weather associated with climate change;
• The ability to successfully operate electric generating facilities and deliver electricity to 
customers including direct or indirect effects to the company resulting from an incident 
that affects the United States electric grid or generating resources;

• The ability to obtain the necessary permits and approvals and to complete necessary 
or desirable pipeline expansion or infrastructure projects in our natural gas business; 

• Operational interruptions to our natural gas distribution and transmission activities;
• The availability of adequate interstate pipeline transportation capacity and natural gas supply;
• The impact on facilities and business from a terrorist attack, cybersecurity threats, 

data security breaches, operational accidents, information technology failures or other 
catastrophic events, such as fires, explosions, pandemic health events or other similar 
occurrences;

• The inherent risks associated with the operation of nuclear facilities, including 

environmental, health, safety, regulatory and financial risks, including the financial 
stability of third-party service providers;

• The timing and extent of changes in commodity prices and interest rates and the ability 
to recover such costs through the regulatory process, where appropriate, and their 
impact on liquidity positions and the value of underlying assets;

• The results of financing efforts, including the ability to obtain financing on favorable 

terms, which can be affected by various factors, including credit ratings, interest rate 
fluctuations, compliance with debt covenants and conditions and general market and 
economic conditions;

• Credit ratings of the Duke Energy Registrants may be different from what is expected;
• Declines in the market prices of equity and fixed-income securities and resultant cash 
funding requirements for defined benefit pension plans, other post-retirement benefit 
plans and nuclear decommissioning trust funds;

• Construction and development risks associated with the completion of the Duke Energy 
Registrants’ capital investment projects, including risks related to financing, obtaining 
and complying with terms of permits, meeting construction budgets and schedules and 
satisfying operating and environmental performance standards, as well as the ability to 
recover costs from customers in a timely manner, or at all;

• Changes in rules for regional transmission organizations, including changes in rate 

designs and new and evolving capacity markets, and risks related to obligations created 
by the default of other participants;

• The ability to control operation and maintenance costs;
• The level of creditworthiness of counterparties to transactions;
• The ability to obtain adequate insurance at acceptable costs;
• Employee workforce factors, including the potential inability to attract and retain key 

personnel;

• The ability of subsidiaries to pay dividends or distributions to Duke Energy Corporation 

holding company (the Parent);

• The performance of projects undertaken by our nonregulated businesses and the 

success of efforts to invest in and develop new opportunities;

• The effect of accounting pronouncements issued periodically by accounting standard-

setting bodies;

• The impact of United States tax legislation to our financial condition, results of 

operations or cash flows and our credit ratings; 

• The impacts from potential impairments of goodwill or equity method investment carrying 

values; and

• The ability to implement our business strategy, including enhancing existing technology systems.

Additional risks and uncertainties are identified and discussed in the Duke Energy 

Registrants’ reports filed with the SEC and available at the SEC’s website at sec.gov. In light 
of these risks, uncertainties and assumptions, the events described in the forward-looking 
statements might not occur or might occur to a different extent or at a different time than 
described. Forward-looking statements speak only as of the date they are made and the Duke 
Energy Registrants expressly disclaim an obligation to publicly update or revise any forward-
looking statements, whether as a result of new information, future events or otherwise.

segments: Electric Utilities and Infrastructure, Gas Utilities and Infrastructure 
and Commercial Renewables. The remainder of Duke Energy’s operations is 
presented as Other. Duke Energy’s chief operating decision-maker routinely 
reviews financial information about each of these business segments in 
deciding how to allocate resources and evaluate the performance of the 
business. For additional information on each of these business segments, 
including financial and geographic information, see Note 3 to the Consolidated 
Financial Statements, “Business Segments.” The following sections describe the 
business and operations of each of Duke Energy’s business segments, as well 
as Other.

ELECTRIC UTILITIES AND INFRASTRUCTURE

Electric Utilities and Infrastructure conducts operations primarily 
through the regulated public utilities of Duke Energy Carolinas, Duke Energy 
Progress, Duke Energy Florida, Duke Energy Indiana and Duke Energy Ohio. 
Electric Utilities and Infrastructure provides retail electric service through the 
generation, transmission, distribution and sale of electricity to approximately 
7.8 million customers within the Southeast and Midwest regions of the U.S. The

The number of residential and general service customers within the 
Electric Utilities and Infrastructure service territory is expected to increase over 
time. While economic conditions within the service territory remain strong, 
sales growth continues to be influenced by adoption of energy efficiencies and 
self-generation. Residential sales for 2019 compared to 2018 declined. The 
continued adoption of more efficient structures and appliances is expected to 
continue to drive average usage per customer lower over time. However, the 
continued adoption of more efficient housing and appliances is expected to 
have a negative impact on average usage per residential customer over time.

In Ohio, Electric Utilities and Infrastructure conducts competitive auctions 

for electricity supply. The cost of energy purchased through these auctions is 
recovered from retail customers. Electric Utilities and Infrastructure earns retail 
margin in Ohio on the transmission and distribution of electricity, but not on the 
cost of the underlying energy.

Competition in the regulated electric distribution business is primarily 

from the development and deployment of alternative energy sources including 
on-site generation from industrial customers and distributed generation, such 
as private solar, at residential, general service and/or industrial customer sites.

Seasonality and the Impact of Weather

Wholesale

Revenues and costs are influenced by seasonal weather patterns. Peak 
sales of electricity occur during the summer and winter months, which results 
in higher revenue and cash flows during these periods. By contrast, lower sales 
of electricity occur during the spring and fall, allowing for scheduled plant 
maintenance. Residential and general service customers are more impacted by 
weather than industrial customers. Estimated weather impacts are based on 
actual current period weather compared to normal weather conditions. Normal 
weather conditions are defined as the long-term average of actual historical 
weather conditions.

The estimated impact of weather on earnings is based on the temperature 

variances from a normal condition and customers’ historic usage patterns. 
The methodology used to estimate the impact of weather does not consider all 
variables that may impact customer response to weather conditions such as 
humidity in the summer or wind chill in the winter. The precision of this estimate 
may also be impacted by applying long-term weather trends to shorter-term 
periods.

Heating-degree days measure the variation in weather based on 

the extent the average daily temperature falls below a base temperature. 
Cooling-degree days measure the variation in weather based on the extent the 
average daily temperature rises above the base temperature. Each degree of 
temperature below the base temperature counts as one heating-degree day 
and each degree of temperature above the base temperature counts as one 
cooling-degree day.

Competition

Retail

Electric Utilities and Infrastructure’s businesses operate as the sole 
supplier of electricity within their service territories, with the exception of Ohio, 
which has a competitive electricity supply market for generation service. Electric 
Utilities and Infrastructure owns and operates facilities necessary to generate, 
transmit, distribute and sell electricity. Services are priced by state commission 
approved rates designed to include the costs of providing these services and 
a reasonable return on invested capital. This regulatory policy is intended to 
provide safe and reliable electricity at fair prices.

Duke Energy competes with other utilities and merchant generators for 

bulk power sales, sales to municipalities and cooperatives and wholesale 
transactions under primarily cost-based contracts approved by FERC. The 
principal factors in competing for these sales are availability of capacity and 
power, reliability of service and price. Prices are influenced primarily by market 
conditions and fuel costs.

Increased competition in the wholesale electric utility industry and 
the availability of transmission access could affect Electric Utilities and 
Infrastructure’s load forecasts, plans for power supply and wholesale energy 
sales and related revenues. Wholesale energy sales will be impacted by the 
extent to which additional generation is available to sell to the wholesale market 
and the ability of Electric Utilities and Infrastructure to attract new customers 
and to retain existing customers.

Energy Capacity and Resources

Electric Utilities and Infrastructure owns approximately 51,144 MW of 

generation capacity. For additional information on owned generation facilities, 
see Item 2, “Properties.”

Energy and capacity are also supplied through contracts with other 
generators and purchased on the open market. Factors that could cause 
Electric Utilities and Infrastructure to purchase power for its customers may 
include, but are not limited to, generating plant outages, extreme weather 
conditions, generation reliability, demand growth and price. Electric Utilities 
and Infrastructure has interconnections and arrangements with its neighboring 
utilities to facilitate planning, emergency assistance, sale and purchase of 
capacity and energy and reliability of power supply.

Electric Utilities and Infrastructure’s generation portfolio is a balanced mix 

of energy resources having different operating characteristics and fuel sources 
designed to provide energy at the lowest possible cost to meet its obligation to 
serve retail customers. All options, including owned generation resources and 
purchased power opportunities, are continually evaluated on a real-time basis 
to select and dispatch the lowest-cost resources available to meet system load 
requirements.

Natural Gas and Fuel Oil

Natural gas and fuel oil supply, transportation and storage for Electric 

Utilities and Infrastructure’s generation fleet is purchased under standard 
industry agreements from various suppliers, including Piedmont. Natural gas 
supply agreements typically provide for a percentage of forecasted burns 
being procured over time, with varied expiration dates. Electric Utilities and 
Infrastructure believes it has access to an adequate supply of natural gas and 
fuel oil for the reasonably foreseeable future.

Electric Utilities and Infrastructure has certain dual-fuel generating 

facilities that can operate utilizing both natural gas and fuel oil. The cost of 
Electric Utilities and Infrastructure’s natural gas and fuel oil is fixed price 
or determined by published market prices as reported in certain industry 
publications, plus any transportation and freight costs. Duke Energy Carolinas, 
Duke Energy Progress, Duke Energy Florida and Duke Energy Indiana use 
derivative instruments to manage a portion of their exposure to price 
fluctuations for natural gas. For Duke Energy Florida, there is currently an 
agreed to moratorium with the FPSC on future hedging of natural gas prices.
Electric Utilities and Infrastructure has firm interstate and intrastate 

natural gas transportation agreements and storage agreements in place 
to support generation needed for load requirements. Electric Utilities and 
Infrastructure may purchase additional shorter-term natural gas transportation 
and utilize natural gas interruptible transportation agreements to support 
generation needed for load requirements. The Electric Utilities and Infrastructure 
natural gas plants are served by various supply zones and multiple pipelines.

involve the mining and milling of uranium ore to produce uranium concentrates 
and services to convert, enrich and fabricate fuel assemblies.

Electric Utilities and Infrastructure has contracted for uranium materials 

and services to fuel its nuclear reactors. Uranium concentrates, conversion 
services and enrichment services are primarily met through a diversified portfolio 
of long-term supply contracts. The contracts are diversified by supplier, country 
of origin and pricing. Electric Utilities and Infrastructure staggers its contracting 
so that its portfolio of long-term contracts covers the majority of its fuel 
requirements in the near term and decreasing portions of its fuel requirements 
over time thereafter. Near-term requirements not met by long-term supply 
contracts have been and are expected to be fulfilled with spot market purchases. 
Due to the technical complexities of changing suppliers of fuel fabrication 
services, Electric Utilities and Infrastructure generally sources these services to a 
single domestic supplier on a plant-by-plant basis using multiyear contracts.

Electric Utilities and Infrastructure has entered into fuel contracts that 
cover 100% of its uranium concentrates, conversion services and enrichment 
services requirements through at least 2020 and cover fabrication services 
requirements for these plants through at least 2027. For future requirements not 
already covered under long-term contracts, Electric Utilities and Infrastructure 
believes it will be able to renew contracts as they expire or enter into similar 
contractual arrangements with other suppliers of nuclear fuel materials and 
services.

Coal

Electric Utilities and Infrastructure meets its coal demand through a 
portfolio of long-term purchase contracts and short-term spot market purchase 
agreements. Large amounts of coal are purchased under long-term contracts 
with mining operators who mine both underground and at the surface. 
Electric Utilities and Infrastructure uses spot market purchases to meet coal 
requirements not met by long-term contracts. Expiration dates for its long-term 
contracts, which have various price adjustment provisions and market 
reopeners, range from 2020 to 2022 for Duke Energy Carolinas and Duke Energy 
Progress, 2020 to 2021 for Duke Energy Florida and Duke Energy Ohio and 2020 
to 2025 for Duke Energy Indiana. Electric Utilities and Infrastructure expects 
to renew these contracts or enter into similar contracts with other suppliers 
as existing contracts expire, though prices will fluctuate over time as coal 
markets change. Electric Utilities and Infrastructure has an adequate supply 
of coal under contract to meet its hedging guidelines regarding projected future 
consumption. As a result of volatility in natural gas prices and the associated 
impacts on coal-fired dispatch within the generation fleet, coal inventories will 
continue to fluctuate. Electric Utilities and Infrastructure continues to actively 
manage its portfolio and has worked with suppliers to obtain increased flexibility 
in its coal contracts.

Coal purchased for the Carolinas is primarily produced from mines in 
Central Appalachia, Northern Appalachia and the Illinois Basin. Coal purchased 
for Florida is primarily produced from mines in Colorado and the Illinois Basin. 
Coal purchased for Kentucky is produced from mines along the Ohio River in 
Illinois, Ohio, West Virginia and Pennsylvania. Coal purchased for Indiana is 
primarily produced in Indiana and Illinois. The current average sulfur content 
of coal purchased by Electric Utilities and Infrastructure is between 1.5% 
and 2% for Duke Energy Carolinas and Duke Energy Progress, between 2% 
and 3% for Duke Energy Florida, between 2.5% and 3% for Duke Energy Ohio 
and between 1.5% and 3% for Duke Energy Indiana. Electric Utilities and 
Infrastructure’s environmental controls, in combination with the use of SO2 
emission allowances, enable Electric Utilities and Infrastructure to satisfy 
current SO2 emission limitations for its existing facilities.

PART IPurchased Power

Electric Utilities and Infrastructure purchases a portion of its capacity 
and system requirements through purchase obligations, leases and purchase 
capacity contracts. Electric Utilities and Infrastructure believes it can obtain 

The following table summarizes purchased power for the previous three years:

Inventory

Electric Utilities and Infrastructure must maintain an adequate stock 

of fuel and materials and supplies in order to ensure continuous operation of 
generating facilities and reliable delivery to customers. As of December 31, 2019, 
the inventory balance for Electric Utilities and Infrastructure was approximately 
$3 billion. For additional information on inventory, see Note 1 to the Consolidated 
Financial Statements, “Summary of Significant Accounting Policies.”

Ash Basin Management

During 2015, EPA issued regulations related to the management of CCR 

from power plants. These regulations classify CCR as nonhazardous waste 
under the Resource Conservation and Recovery Act (RCRA) and apply to 
electric generating sites with new and existing landfills and new and existing 
surface impoundments and establishes requirements regarding landfill design, 
structural integrity design and assessment criteria for surface impoundments, 
groundwater monitoring, protection and remedial procedures and other 
operational and reporting procedures for the disposal and management of CCR. 
In addition to the federal regulations, CCR landfills and surface impoundments 
(ash basins or impoundments) will continue to be regulated by existing state 
laws, regulations and permits, including the Coal Ash Act in North Carolina.
Electric Utilities and Infrastructure has and will periodically submit to 
applicable authorities required site-specific coal ash impoundment remediation 
or closure plans. These plans and all associated permits must be approved before 
any work can begin. Closure activities began in 2015 at the four sites specified as 
high priority by the Coal Ash Act and at the W.S. Lee Steam Station site in South 
Carolina in connection with other legal requirements. Excavation at these sites 
involves movement of CCR materials to off-site locations for use as structural fill, 
to appropriate engineered off-site or on-site lined landfills or conversion of the ash 
for beneficial use. Duke Energy has completed excavation of coal ash regulated by 
the Coal Ash Act at three of the four high-priority sites. At other sites, planning and 
closure methods have been studied and factored into the estimated retirement and 
management costs, and closure activities have commenced.

The Coal Ash Act leaves the decision on cost recovery determinations 
related to closure of coal ash surface impoundments to the normal ratemaking 
processes before utility regulatory commissions. Duke Energy Carolinas and 
Duke Energy Progress have included compliance costs associated with the 
EPA CCR rule and the Coal Ash Act in their respective rate case filings. During 
2017, Duke Energy Carolinas’ and Duke Energy Progress’ wholesale contracts 
were amended to include the recovery of expenditures related to AROs for the 
closure of coal ash basins. The amended contracts have retail disallowance 
parity or provisions limiting challenges to CCR cost recovery actions at 
FERC. FERC approved the amended wholesale rate schedules in 2017. For 
additional information on the ash basins and recovery, see Item 7, “Other 
Matters” and Notes 4, 5 and 10 to the Consolidated Financial Statements, 
“Regulatory Matters,” “Commitments and Contingencies” and “Asset Retirement 
Obligations,” respectively.

Nuclear Matters

Duke Energy owns, wholly or partially, 11 operating nuclear reactors 
located at six operating stations. The Crystal River Unit 3 permanently ceased 
operation in February 2013. Nuclear insurance includes: nuclear liability 
coverage; property damage coverage; nuclear accident decontamination and 
premature decommissioning coverage; and accidental outage coverage for 
losses in the event of a major accidental outage. Joint owners reimburse Duke 
Energy for certain expenses associated with nuclear insurance in accordance 
with joint owner agreements. The Price-Anderson Act requires plant owners to 
provide for public nuclear liability claims resulting from nuclear incidents to the 
maximum total financial protection liability, which is approximately $13.9 billion. 
For additional information on nuclear insurance see Note 5 to the Consolidated 
Financial Statements, “Commitments and Contingencies.”

Duke Energy has a significant future financial commitment to dispose of 

spent nuclear fuel and decommission and decontaminate each plant safely. The 
NCUC, PSCSC and FPSC require Duke Energy to update their cost estimates for 
decommissioning their nuclear plants every five years.

The following table summarizes the fair value of NDTF investments and the most recent site-specific nuclear decommissioning cost studies. Decommissioning 

costs are stated in 2018 or 2019 dollars, depending on the year of the cost study, and include costs to decommission plant components not subject to radioactive 
contamination.

(d)  Duke Energy Progress’ site-specific nuclear decommissioning cost study, which was completed in 2019, is expected to be filed with the NCUC and PSCSC during the first quarter of 2020. Duke Energy Progress is expected to 

file an updated funding study with NCUC and PSCSC in the third quarter of 2020.

(e)  During 2019, Duke Energy Florida reached an agreement to transfer decommissioning work for Crystal River Unit 3 to a third party. The agreement requires regulatory approval from the NRC and the FPSC.

8

PART IThe NCUC, PSCSC, FPSC and FERC have allowed Electric Utilities and 

Infrastructure to recover estimated decommissioning costs through retail and 
wholesale rates over the expected remaining service periods of their nuclear 
stations. Electric Utilities and Infrastructure believes the decommissioning costs 
being recovered through rates, when coupled with the existing fund balances 
and expected fund earnings, will be sufficient to provide for the cost of future 
decommissioning. For additional information, see Note 10 to the Consolidated 
Financial Statements, “Asset Retirement Obligations.”

The Nuclear Waste Policy Act of 1982 (as amended) provides the framework 

for development by the federal government of interim storage and permanent 
disposal facilities for high-level radioactive waste materials. The government has 
not yet developed a storage facility or disposal capacity, so Electric Utilities and 
Infrastructure will continue to store spent fuel on its reactor sites.

Under federal law, the DOE is responsible for the selection and 
construction of a facility for the permanent disposal of spent nuclear fuel 
and high-level radioactive waste. The DOE terminated the project to license 
and develop a geologic repository at Yucca Mountain, Nevada in 2010, and is 
currently taking no action to fulfill its responsibilities to dispose of spent fuel.
Until the DOE begins to accept the spent nuclear fuel, Duke Energy 
Carolinas, Duke Energy Progress and Duke Energy Florida will continue to safely 
manage their spent nuclear fuel. Under current regulatory guidelines, Harris 
has sufficient storage capacity in its spent fuel pools through the expiration 
of its renewed operating license. With certain modifications and approvals by 
the NRC to expand the on-site dry cask storage facilities, spent nuclear fuel 
dry storage facilities will be sufficient to provide storage space of spent fuel 
through the expiration of the operating licenses, including any license renewals, 
for Brunswick, Catawba, McGuire, Oconee and Robinson. Crystal River Unit 3 
ceased operation in 2013 and was placed in a SAFSTOR condition in January 
2018. As of January 2018, all spent fuel at Crystal River Unit 3 has been 
transferred from the spent fuel pool to dry storage at an on-site independent 
spent fuel storage installation.

The nuclear power industry faces uncertainties with respect to the cost 

and long-term availability of disposal sites for spent nuclear fuel and other 
radioactive waste, compliance with changing regulatory requirements, capital 
outlays for modifications and new plant construction.

Electric Utilities and Infrastructure is subject to the jurisdiction of the NRC 

for the design, construction and operation of its nuclear generating facilities. 
The following table includes the current year of expiration of nuclear operating 
licenses for nuclear stations in operation. During 2019, Duke Energy announced 
its intention to seek 20-year operating license renewals for each of the reactors 
it operates in Duke Energy Carolinas and Duke Energy Progress. 

The NRC has acknowledged permanent cessation of operation and 
permanent removal of fuel from the reactor vessel at Crystal River Unit 3. 
Therefore, the license no longer authorizes operation of the reactor. For 
additional information on nuclear decommissioning activity, see Notes 4 and 
10 to the Consolidated Financial Statements, “Regulatory Matters” and “Asset 
Retirement Obligations,” respectively.

Regulation

State

The state electric utility commissions approve rates for Duke Energy’s 
retail electric service within their respective states. The state electric utility 
commissions, to varying degrees, have authority over the construction and 
operation of Electric Utilities and Infrastructure’s generating facilities. CPCNs 
issued by the state electric utility commissions, as applicable, authorize Electric 
Utilities and Infrastructure to construct and operate its electric facilities and 
to sell electricity to retail and wholesale customers. Prior approval from the 
relevant state electric utility commission is required for the entities within 
Electric Utilities and Infrastructure to issue securities. The underlying concept 
of utility ratemaking is to set rates at a level that allows the utility to collect 
revenues equal to its cost of providing service plus earn a reasonable rate of 
return on its invested capital, including equity.

In addition to rates approved in base rate cases, each of the state electric 
utility commissions allow recovery of certain costs through various cost-recovery 
clauses to the extent the respective commission determines in periodic hearings 
that such costs, including any past over or under-recovered costs, are prudent.
Fuel, fuel-related costs and certain purchased power costs are eligible 

for recovery by Electric Utilities and Infrastructure. Electric Utilities and 
Infrastructure uses coal, hydroelectric, natural gas, oil, renewable generation 
and nuclear fuel to generate electricity, thereby maintaining a diverse fuel mix 
that helps mitigate the impact of cost increases in any one fuel. Due to the 
associated regulatory treatment and the method allowed for recovery, changes 
in fuel costs from year to year have no material impact on operating results of 
Electric Utilities and Infrastructure, unless a commission finds a portion of such 
costs to have been imprudent. However, delays between the expenditure for fuel 
costs and recovery from customers can adversely impact the timing of cash 
flows of Electric Utilities and Infrastructure.

midstream properties for Gas Utilities and Infrastructure as of December 31, 2019.

For more information on rate matters and other regulatory proceedings, 

see Note 4 to the Consolidated Financial Statements, “Regulatory Matters.”

Federal

The FERC approves Electric Utilities and Infrastructure’s cost-based 
rates for electric sales to certain power and transmission wholesale customers. 
Regulations of FERC and the state electric utility commissions govern access to 
regulated electric and other data by nonregulated entities and services provided 
between regulated and nonregulated energy affiliates. These regulations affect 
the activities of nonregulated affiliates with Electric Utilities and Infrastructure.
RTOs. PJM and MISO are the ISOs and FERC-approved RTOs for the 
regions in which Duke Energy Ohio and Duke Energy Indiana operate. PJM and 
MISO operate energy, capacity and other markets, and control the day-to-day 
operations of bulk power systems through central dispatch.

Duke Energy Ohio is a member of PJM and Duke Energy Indiana is a 
member of MISO. Transmission owners in these RTOs have turned over control 
of their transmission facilities and their transmission systems are currently 
under the dispatch control of the RTOs. Transmission service is provided on 
a regionwide, open-access basis using the transmission facilities of the RTO 
members at rates based on the costs of transmission service.

Environmental. Electric Utilities and Infrastructure is subject to the 

jurisdiction of the EPA and state and local environmental agencies. For a 
discussion of environmental regulation, see “Environmental Matters” in this 
section. See the “Other Matters” section of Management’s Discussion and 
Analysis for a discussion about potential Global Climate Change legislation 
and other EPA regulations under development and the potential impacts such 
legislation and regulation could have on Duke Energy’s operations.

GAS UTILITIES AND INFRASTRUCTURE

Gas Utilities and Infrastructure conducts natural gas operations primarily 

through the regulated public utilities of Piedmont, Duke Energy Ohio and Duke 
Energy Kentucky. The natural gas operations are subject to the rules and 
regulations of the NCUC, PSCSC, PUCO, KPSC, TPUC, PHMSA and the FERC. Gas 
Utilities and Infrastructure serves residential, commercial, industrial and power 
generation natural gas customers, including customers served by municipalities 
who are wholesale customers. Gas Utilities and Infrastructure has over 1.6 million 
customers, including 1.1 million customers located in North Carolina, South 
Carolina and Tennessee, and an additional 535,000 customers located within 
southwestern Ohio and northern Kentucky. In the Carolinas, Ohio and Kentucky, 

10

PART IThe number of residential, commercial and industrial customers within 

the Gas Utilities and Infrastructure service territory is expected to increase 
over time. Average usage per residential customer is expected to remain flat or 
decline for the foreseeable future; however, decoupled rates in North Carolina 
and various rate design mechanisms in other jurisdictions partially mitigate the 
impact of the declining usage per customer on overall profitability.

Gas Utilities and Infrastructure also owns, operates and has investments 

in various pipeline transmission and natural gas storage facilities.

Natural Gas for Retail Distribution

Gas Utilities and Infrastructure is responsible for the distribution of 
natural gas to retail customers in its North Carolina, South Carolina, Tennessee, 
Ohio and Kentucky service territories. Gas Utilities and Infrastructure’s natural 
gas procurement strategy is to contract primarily with major and independent 
producers and marketers for natural gas supply. It also purchases a diverse 
portfolio of transportation and storage service from interstate pipelines. This 
strategy allows Gas Utilities and Infrastructure to assure reliable natural gas 
supply and transportation for its firm customers during peak winter conditions. 
When firm pipeline services or contracted natural gas supplies are temporarily 
not needed due to market demand fluctuations, Gas Utilities and Infrastructure 
may release these services and supplies in the secondary market under 
FERC-approved capacity release provisions or make wholesale secondary 
market sales. In 2019, firm supply purchase commitment agreements provided 
100% of the natural gas supply for both Piedmont and Duke Energy Ohio.

Impact of Weather

Gas Utilities and Infrastructure revenues are generally protected 
from the impact of weather fluctuations due to the regulatory mechanisms 
that are available in most service territories. In North Carolina, margin 
decoupling provides protection from both weather and other usage variations 
like conservation for residential and commercial customer classes. Margin 
decoupling provides a set revenue per customer independent of actual usage. 
In South Carolina, Tennessee and Kentucky, weather normalization adjusts 
revenues either up or down depending on how much warmer or colder than 
normal a given month has been. Weather normalization adjustments occur 
from November through March in South Carolina, from October through April 
in Tennessee and from November through April in Kentucky. Duke Energy Ohio 
collects most of its non-fuel revenue through a fixed monthly charge that 
is not impacted by usage fluctuations that result from weather changes or 
conservation.

Competition

Gas Utilities and Infrastructure’s businesses operate as the sole provider 

of natural gas service within their retail service territories. Gas Utilities 
and Infrastructure owns and operates facilities necessary to transport and 
distribute natural gas. Gas Utilities and Infrastructure earns retail margin on 
the transmission and distribution of natural gas and not on the cost of the 
underlying commodity. Services are priced by state commission approved rates 
designed to include the costs of providing these services and a reasonable 
return on invested capital. This regulatory policy is intended to provide safe 
and reliable natural gas service at fair prices.

In residential, commercial and industrial customer markets, natural 
gas distribution operations compete with other companies that supply energy, 
primarily electric companies, propane and fuel oil dealers, renewable energy 
providers and coal companies in relation to sources of energy for electric power 
plants, as well as nuclear energy. A significant competitive factor is price. Gas 
Utilities and Infrastructure’s primary product competition is with electricity 
for heating, water heating and cooking. Increases in the price of natural gas 
or decreases in the price of other energy sources could negatively impact 
competitive position by decreasing the price benefits of natural gas to the 
consumer. In the case of industrial customers, such as manufacturing plants, 
adverse economic or market conditions, including higher natural gas costs, could 

cause these customers to suspend business operations or to use alternative 
sources of energy in favor of energy sources with lower per-unit costs.

Higher natural gas costs or decreases in the price of other energy sources 

may allow competition from alternative energy sources for applications that 
have traditionally used natural gas, encouraging some customers to move 
away from natural gas-fired equipment to equipment fueled by other energy 
sources. Competition between natural gas and other forms of energy is also 
based on efficiency, performance, reliability, safety and other non-price factors. 
Technological improvements in other energy sources and events that impair 
the public perception of the non-price attributes of natural gas could erode 
our competitive advantage. These factors in turn could decrease the demand 
for natural gas, impair our ability to attract new customers and cause existing 
customers to switch to other forms of energy or to bypass our systems in favor 
of alternative competitive sources. This could result in slow or no customer 
growth and could cause customers to reduce or cease using our product, 
thereby reducing our ability to make capital expenditures and otherwise grow 
our business, adversely affecting our earnings.

Pipeline and Storage Investments

Duke Energy, through its Gas Utilities and Infrastructure segment, is a 
47% equity member of ACP, which plans to build and own the proposed ACP 
pipeline, an approximately 600-mile interstate natural gas pipeline, regulated 
by FERC. The ACP pipeline is intended to transport diverse natural gas supplies 
into southeastern markets. Duke Energy Carolinas, Duke Energy Progress and 
Piedmont, among others, will be customers of ACP. ACP expects mechanical 
completion of the full project in late 2021 with in-service likely in the first 
half of 2022. Abnormal weather, work delays (including delays due to judicial 
or regulatory action) and other conditions may result in cost or schedule 
modifications, a suspension of AFUDC for ACP and/or impairment charges 
potentially material to Duke Energy’s cash flows, financial position and results 
of operations. ACP and Duke Energy will continue to consider their options with 
respect to the foregoing in light of their existing contractual and legal obligations.
Gas Utilities and Infrastructure also has a 7.5% equity ownership interest 
in Sabal Trail. Sabal Trail is a joint venture that owns the Sabal Trail Natural Gas 
Pipeline (Sabal Trail pipeline) to transport natural gas to Florida, regulated by 
FERC. The Sabal Trail phase one mainline was placed into service in July 2017 
and traverses Alabama, Georgia and Florida. The remaining lateral line to the 
Duke Energy Florida’s Citrus County CC was placed into service in March 2018. 
In May 2019, construction activities began as planned on Phase II of Sabal 
Trail. Phase II will add approximately 200,000 Dth of capacity to the Sabal Trail 
pipeline and is expected to achieve in-service in May 2020.

Gas Utilities and Infrastructure had a 24% equity ownership interest in 
Constitution, an interstate pipeline development company formed to develop, 
construct, own and operate a 124-mile natural gas pipeline and related 
facilities, regulated by FERC. Constitution was slated to transport natural 
gas supplies from the Marcellus supply region in northern Pennsylvania to 
major northeastern markets. As of February 5, 2020, the Constitution partners 
formally resolved to initiate the dissolution of Constitution, and to terminate the 
Constitution Pipeline project.

Duke Energy, through its Gas Utilities and Infrastructure segment, has a 
21.49% equity ownership interest in Cardinal, an intrastate pipeline located in 
North Carolina regulated by the NCUC, a 45% equity ownership in Pine Needle, 
an interstate liquefied natural gas storage facility located in North Carolina and 
a 50% equity ownership interest in Hardy Storage, an underground interstate 
natural gas storage facility located in Hardy and Hampshire counties in West 
Virginia. Pine Needle and Hardy Storage are regulated by FERC.

KO Transmission, a wholly owned subsidiary of Duke Energy Ohio, is an 
interstate pipeline company engaged in the business of transporting natural 
gas and is subject to the rules and regulations of FERC. KO Transmission’s 
90-mile pipeline supplies natural gas to Duke Energy Ohio and interconnects 
with the Columbia Gulf Transmission pipeline and Tennessee Gas Pipeline. 
An approximately 70-mile portion of KO Transmission’s pipeline facilities is 
co-owned by Columbia Gas Transmission Corporation.

“Regulatory Matters,” “Investments in Unconsolidated Affiliates” and “Variable 
Interest Entities,” respectively, for further information on Duke Energy’s pipeline 
investments.

Inventory

Gas Utilities and Infrastructure must maintain adequate natural gas 
inventory in order to provide reliable delivery to customers. As of December 31, 
2019, the inventory balance for Gas Utilities and Infrastructure was $111 
million. For more information on inventory, see Note 1 to the Consolidated 
Financial Statements, “Summary of Significant Accounting Policies.”

Regulation

State

The state gas utility commissions approve rates for Duke Energy’s 
retail natural gas service within their respective states. The state gas utility 
commissions, to varying degrees, have authority over the construction and 
operation of Gas Utilities and Infrastructure’s natural gas distribution facilities. 

CPCNs issued by the state gas utility commissions or other government 
agencies, as applicable, authorize Gas Utilities and Infrastructure to construct 
and operate its natural gas distribution facilities and to sell natural gas to retail 
and wholesale customers. Prior approval from the relevant state gas utility 
commission is required for Gas Utilities and Infrastructure to issue securities. 
The underlying concept of utility ratemaking is to set rates at a level that 
allows the utility to collect revenues equal to its cost of providing service plus a 
reasonable rate of return on its invested capital, including equity.

In addition to amounts collected from customers through approved base 
rates, each of the state gas utility commissions allow recovery of certain costs 
through various cost-recovery clauses to the extent the respective commission 
determines in periodic hearings that such costs, including any past over- or 
under-recovered costs, are prudent.

Natural gas costs are eligible for recovery by Gas Utilities and 
Infrastructure. Due to the associated regulatory treatment and the method 
allowed for recovery, changes in natural gas costs from year to year have no 
material impact on operating results of Gas Utilities and Infrastructure, unless 
a commission finds a portion of such costs to have not been prudent. However, 
delays between the expenditure for natural gas and recovery from customers 
can adversely impact the timing of cash flows of Gas Utilities and Infrastructure.

PART ICOMMERCIAL RENEWABLES

Commercial Renewables primarily acquires, develops, builds, operates 

and owns wind and solar renewable generation throughout the continental 
U.S. The portfolio includes nonregulated renewable energy and energy storage 
businesses. On April 24, 2019, Duke Energy executed an agreement to sell 
a minority interest in a portion of certain renewable assets. The sale closed 
on September 6, 2019, See Note 2 to the Consolidated Financial Statements, 
“Acquisitions and Dispositions,” for additional information.

Commercial Renewables’ renewable energy includes utility-scale wind 
and solar generation assets, distributed solar generation assets, distributed fuel 

cell assets and a battery storage project, which total 2,282 MW across 19 states 
from 22 wind facilities, 126 solar projects, 11 fuel cell locations and one battery 
storage facility. Revenues are primarily generated by selling the power produced 
from renewable generation through long-term contracts to utilities, electric 
cooperatives, municipalities and corporate customers. In most instances, 
these customers have obligations under state-mandated renewable energy 
portfolio standards or similar state or local renewable energy goals. Energy and 
renewable energy credits generated by wind and solar projects are generally 
sold at contractual prices. The following map shows the locations of renewable 
generation facilities of which Commercial Renewables has an ownership interest 
as of December 31, 2019.

Solar and Wind

As eligible projects are placed in service, Commercial Renewables 
recognizes either PTCs as power is generated by wind projects over 10 years or 
ITCs when the renewable solar, fuel cells or wind project achieves commercial 
availability. ITCs are recognized over the useful life of the asset as a reduction 
to depreciation expense. Benefits of the tax basis adjustment due to the ITC 
are recognized in income in the year of commercial availability. The ITC is being 
phased down from the current 2019 rate of 30% to a permanent 10% rate if 
construction begins after 2021. The PTC is being phased out and wind turbines 
will earn 10 years of PTCs at phased-out rates if construction began in 2017 
through 2020.

As part of its growth strategy, Commercial Renewables has expanded its 

investment portfolio through the addition of distributed solar companies and 
projects, energy storage systems and energy management solutions specifically 
tailored to commercial businesses. These investments include REC Solar, 
a California-based provider of solar installations for retail, manufacturing, 
agriculture, technology, government and nonprofit customers across the U.S. 
and Phoenix Energy Technologies Inc., a California-based provider of enterprise 
energy management and information software to commercial businesses.

Commercial Renewables has entered into agreements for certain 
of its generating assets that are held by LLCs whose members include a 
noncontrolling tax equity investor. The allocation of tax attributes and cash 
flows to the tax equity investor are governed by the provisions of the LLC 

agreements. The GAAP earnings allocations to the tax equity investors can 
result in variability in earnings to Duke Energy. As part of its growth strategy, 
Commercial Renewables expects to enter into these arrangements for future 
generating assets.

For additional information on Commercial Renewables’ generation 

facilities, see Item 2, “Properties.”

Market Environment and Competition

Commercial Renewables primarily competes for wholesale contracts for 
the generation and sale of electricity from generation assets it either develops 
or acquires and owns. The market price of commodities and services, along 
with the quality and reliability of services provided, drive competition in the 
wholesale energy business. The number and type of competitors may vary 
based on location, generation type and project size. Commercial Renewables’ 
main competitors include other nonregulated generators and wholesale power 
providers.

Sources of Electricity

Commercial Renewables relies on wind, solar, fuel cells and battery 

resources for its generation of electric energy.

13

PART IRegulation

Commercial Renewables is subject to regulation at the federal level, 

primarily from the FERC. Regulations of the FERC govern access to regulated 
market information by nonregulated entities and services provided between 
regulated and nonregulated utilities.

OTHER

The remainder of Duke Energy’s operations is presented as Other. While 

it is not a business segment, Other primarily includes interest expense on 
holding company debt, unallocated corporate costs including costs to achieve 
strategic acquisitions, amounts related to certain companywide initiatives and 
contributions made to the Duke Energy Foundation. Other also includes Bison 
and an investment in NMC.

The Duke Energy Foundation is a nonprofit organization funded by Duke 

Energy shareholders that makes charitable contributions to selected nonprofits 
and government subdivisions.

Bison, a wholly owned subsidiary of Duke Energy, is a captive insurance 
company with the principal activity of providing Duke Energy subsidiaries with

indemnification for financial losses primarily related to property, workers’ 
compensation and general liability.

Duke Energy owns a 17.5% equity interest in NMC. The joint venture 
company has production facilities in Jubail, Saudi Arabia, where it manufactures 
certain petrochemicals and plastics. The company annually produces 
approximately 1 million metric tons each of MTBE and methanol and has the 
capacity to produce 50,000 metric tons of polyacetal. The main feedstocks to 
produce these products are natural gas and butane. Duke Energy records the 
investment activity of NMC using the equity method of accounting and retains 
25% of NMC’s board of directors’ representation and voting rights.

Employees

On December 31, 2019, Duke Energy had a total of 28,793 employees 

on its payroll. The total includes 5,399 employees who are represented by 
labor unions under various collective bargaining agreements that generally 
cover wages, benefits, working practices, and other terms and conditions of

In addition to other disclosures within this Form 10-K, including 
“Management’s Discussion and Analysis of Financial Condition and Results 
of Operations – Matters Impacting Future Results” for each registrant in 
Item 7, and other documents filed with the SEC from time to time, the following 
factors should be considered in evaluating Duke Energy and its subsidiaries. 
Such factors could affect actual results of operations and cause results to 
differ substantially from those currently expected or sought. Unless otherwise 
indicated, risk factors discussed below generally relate to risks associated with 
all of the Duke Energy Registrants. Risks identified at the Subsidiary Registrant 
level are generally applicable to Duke Energy.

BUSINESS STRATEGY RISKS

Duke Energy’s future results could be adversely affected if it is unable to 
implement its business strategy.

Duke Energy’s results of operations depend, in significant part, on the 

extent to which it can implement its business strategy successfully. Duke 
Energy’s strategy, which includes transforming the customer experience, 
modernizing the energy grid, generating cleaner energy and working to achieve 
net-zero carbon emissions by 2050, expanding the natural gas infrastructure, 
modernizing the regulatory construct and digital transformation, is subject to 
business, economic and competitive uncertainties and contingencies, many of 
which are beyond its control. As a consequence, Duke Energy may not be able 
to fully implement or realize the anticipated results of its strategy.

REGULATORY, LEGISLATIVE AND LEGAL RISKS

The Duke Energy Registrants’ regulated utility revenues, earnings and 
results are dependent on state legislation and regulation that affect 
electric generation, electric and natural gas transmission, distribution and 
related activities, which may limit their ability to recover costs.

The Duke Energy Registrants’ regulated electric and natural gas utility 

businesses are regulated on a cost-of-service/rate-of-return basis subject to 
statutes and regulatory commission rules and procedures of North Carolina, 
South Carolina, Florida, Ohio, Tennessee, Indiana and Kentucky. If the Duke 
Energy Registrants’ regulated utility earnings exceed the returns established 
by the state utility commissions, retail electric and natural gas rates may 
be subject to review and possible reduction by the commissions, which may 
decrease the Duke Energy Registrants’ earnings. Additionally, if regulatory 
bodies do not allow recovery of costs incurred in providing service, or do not do 
so on a timely basis, the Duke Energy Registrants’ earnings could be negatively 
impacted.

If legislative and regulatory structures were to evolve in such a way that 

the Duke Energy Registrants’ exclusive rights to serve their regulated customers 
were eroded, their earnings could be negatively impacted. Federal and state 
regulations, laws and other efforts designed to promote and expand the use 
of EE measures and distributed generation technologies, such as private solar 
and battery storage, in Duke Energy service territories could result in customers 
leaving the electric distribution system and an increase in customer net energy 
metering, which allows customers with private solar to receive bill credits for 
surplus power at the full retail amount. Over time, customer adoption of these 
technologies and increased EE could result in excess generation resources as 
well as stranded costs if Duke Energy is not able to fully recover the costs and 
investment in generation.

16

PART IState regulators have approved various mechanisms to stabilize natural 

gas utility margins, including margin decoupling in North Carolina and rate 
stabilization in South Carolina. State regulators have approved other margin 
stabilizing mechanisms that, for example, allow for recovery of margin losses 
associated with negotiated transactions designed to retain large volume 
customers that could use alternative fuels or that may otherwise directly access 
natural gas supply through their own connection to an interstate pipeline. If 
regulators decided to discontinue the Duke Energy Registrants’ use of tariff 
mechanisms, it would negatively impact results of operations, financial position 
and cash flows. In addition, regulatory authorities also review whether natural 
gas costs are prudently incurred and can disallow the recovery of a portion 
of natural gas costs that the Duke Energy Registrants seek to recover from 
customers, which would adversely impact earnings.

The rates that the Duke Energy Registrants’ regulated utility businesses 
are allowed to charge are established by state utility commissions in rate 
case proceedings, which may limit their ability to recover costs and earn 
an appropriate return on investment.

The rates that the Duke Energy Registrants’ regulated utility business are 

allowed to charge significantly influences the results of operations, financial 
position and cash flows of the Duke Energy Registrants. The regulation of the 
rates that the regulated utility businesses charge customers is determined, 
in large part, by state utility commissions in rate case proceedings. Negative 
decisions made by these regulators, or by any court on appeal of a rate 
case proceeding, could have a material adverse effect on the Duke Energy 
Registrants’ results of operations, financial position or cash flows and affect the 
ability of the Duke Energy Registrants to recover costs and an appropriate return 
on the significant infrastructure investments being made.

Deregulation or restructuring in the electric industry may result in 
increased competition and unrecovered costs that could adversely affect 
the Duke Energy Registrants’ results of operations, financial position or 
cash flows and their utility businesses.

Increased competition resulting from deregulation or restructuring 
legislation could have a significant adverse impact on the Duke Energy 
Registrants’ results of operations, financial position or cash flows. If the 
retail jurisdictions served by the Duke Energy Registrants become subject to 
deregulation, the impairment of assets, loss of retail customers, lower profit 
margins or increased costs of capital, and recovery of stranded costs could have 
a significant adverse financial impact on the Duke Energy Registrants. Stranded 
costs primarily include the generation assets of the Duke Energy Registrants 
whose value in a competitive marketplace may be less than their current book 
value, as well as above-market purchased power commitments from QFs from 
whom the Duke Energy Registrants are legally obligated to purchase energy 
at an avoided cost rate under PURPA. The Duke Energy Registrants cannot 
predict the extent and timing of entry by additional competitors into the electric 
markets. The Duke Energy Registrants cannot predict if or when they will be 
subject to changes in legislation or regulation, nor can they predict the impact of 
these changes on their results of operations, financial position or cash flows.

The Duke Energy Registrants’ businesses are subject to extensive federal 
regulation and a wide variety of laws and governmental policies, including 
taxes, that may change over time in ways that affect operations and costs.

The Duke Energy Registrants are subject to regulations under a wide 

variety of U.S. federal and state regulations and policies, including by FERC, 
NRC, EPA and various other federal agencies as well as the North American 
Electric Reliability Corporation. Regulation affects almost every aspect of the 
Duke Energy Registrants’ businesses, including, among other things, their ability 
to: take fundamental business management actions; determine the terms and 
rates of transmission and distribution services; make acquisitions; issue equity 

17

or debt securities; engage in transactions with other subsidiaries and affiliates; 
and pay dividends upstream to the Duke Energy Registrants. Changes to federal 
regulations are continuous and ongoing. There can be no assurance that laws, 
regulations and policies will not be changed in ways that result in material 
modifications of business models and objectives or affect returns on investment 
by restricting activities and products, subjecting them to escalating costs, 
causing delays, or prohibiting them outright.

The Duke Energy Registrants are subject to numerous environmental 
laws and regulations requiring significant capital expenditures that can 
increase the cost of operations, and which may impact or limit business 
plans, or cause exposure to environmental liabilities.

The Duke Energy Registrants are subject to numerous environmental laws 

and regulations affecting many aspects of their present and future operations, 
including CCRs, air emissions, water quality, wastewater discharges, solid 
waste and hazardous waste. These laws and regulations can result in 
increased capital, operating and other costs. These laws and regulations 
generally require the Duke Energy Registrants to obtain and comply with a wide 
variety of environmental licenses, permits, inspections and other approvals. 
Compliance with environmental laws and regulations can require significant 
expenditures, including expenditures for cleanup costs and damages arising 
from contaminated properties. Failure to comply with environmental regulations 
may result in the imposition of fines, penalties and injunctive measures 
affecting operating assets. The steps the Duke Energy Registrants could be 
required to take to ensure their facilities are in compliance could be prohibitively 
expensive. As a result, the Duke Energy Registrants may be required to shut 
down or alter the operation of their facilities, which may cause the Duke Energy 
Registrants to incur losses. Further, the Duke Energy Registrants may not be 
successful in recovering capital and operating costs incurred to comply with 
new environmental regulations through existing regulatory rate structures 
and their contracts with customers. Also, the Duke Energy Registrants may 
not be able to obtain or maintain from time to time all required environmental 
regulatory approvals for their operating assets or development projects. Delays 
in obtaining any required environmental regulatory approvals, failure to obtain 
and comply with them or changes in environmental laws or regulations to more 
stringent compliance levels could result in additional costs of operation for 
existing facilities or development of new facilities being prevented, delayed or 
subject to additional costs. Although it is not expected that the costs to comply 
with current environmental regulations will have a material adverse effect on 
the Duke Energy Registrants’ results of operations, financial position and cash 
flows due to regulatory cost recovery, the Duke Energy Registrants are at risk 
that the costs of complying with environmental regulations in the future will 
have such an effect.

The EPA has enacted or proposed federal regulations governing the 
management of cooling water intake structures, wastewater and CO2 emissions. 
These regulations may require the Duke Energy Registrants to make additional 
capital expenditures and increase operating and maintenance costs.

Duke Energy Carolinas and Duke Energy Progress are subject to the 
terms of probation set out in judgments of the U.S. District Court for the Eastern 
District of North Carolina on May 14, 2015. The judgments are based on events 
and activities that took place prior to 2015. The terms of probation require the 
companies to comply with certain environmental regulatory obligations related 
to coal ash and subject the two companies to oversight by a Court Appointed 
Monitor. If Duke Energy Carolinas or Duke Energy Progress failed to comply with 
certain coal ash-related environmental laws and regulations or otherwise violated 
the terms of probation, it could result in the imposition of additional penalties, 
including the revocation of probation and re-prosecution of the underlying 
violations. Although it is not expected that the companies will violate the terms of 
probation or that additional material penalties would occur, a significant violation 
of probation could have a material adverse effect on the Duke Energy Registrants’ 
reputation, results of operations, financial position and cash flows.

PART IThe Duke Energy Registrants’ operations, capital expenditures and 
financial results may be affected by regulatory changes related to the 
impacts of global climate change.

There is continued concern, both nationally and internationally, about 

climate change. The EPA and state regulators may adopt and implement 
regulations to restrict emissions of GHGs to address global climate change. 
Increased regulation of GHG emissions could impose significant additional costs 
on the Duke Energy Registrants’ operations, their suppliers and customers. 
Regulatory changes could also result in generation facilities to be retired early 
and result in stranded costs if Duke Energy is not able to fully recover the costs 
and investment in generation.

OPERATIONAL RISKS

The Duke Energy Registrants’ results of operations may be negatively 
affected by overall market, economic and other conditions that are beyond 
their control.

Sustained downturns or sluggishness in the economy generally affect the 
markets in which the Duke Energy Registrants operate and negatively influence 
operations. Declines in demand for electricity or natural gas as a result of 
economic downturns in the Duke Energy Registrants’ regulated service territories 
will reduce overall sales and lessen cash flows, especially as industrial 
customers reduce production and, therefore, consumption of electricity and the 
use of natural gas. Although the Duke Energy Registrants’ regulated electric 
and natural gas businesses are subject to regulated allowable rates of return 
and recovery of certain costs, such as fuel and purchased natural gas costs, 
under periodic adjustment clauses, overall declines in electricity or natural gas 
sold as a result of economic downturn or recession could reduce revenues and 
cash flows, thereby diminishing results of operations. Additionally, prolonged 
economic downturns that negatively impact the Duke Energy Registrants’ results 
of operations and cash flows could result in future material impairment charges 
to write-down the carrying value of certain assets, including goodwill, to their 
respective fair values.

The Duke Energy Registrants also sell electricity into the spot market or 
other competitive power markets on a contractual basis. With respect to such 
transactions, the Duke Energy Registrants are not guaranteed any rate of return 
on their capital investments through mandated rates, and revenues and results 
of operations are likely to depend, in large part, upon prevailing market prices. 
These market prices may fluctuate substantially over relatively short periods 
of time and could reduce the Duke Energy Registrants’ revenues and margins, 
thereby diminishing results of operations.

Factors that could impact sales volumes, generation of electricity and 

market prices at which the Duke Energy Registrants are able to sell electricity 
and natural gas are as follows:

• weather conditions, including abnormally mild winter or summer 
weather that cause lower energy or natural gas usage for heating 
or cooling purposes, as applicable, and periods of low rainfall that 
decrease the ability to operate facilities in an economical manner;

• supply of and demand for energy commodities;

• transmission or transportation constraints or inefficiencies that impact 

nonregulated energy operations;

• availability of competitively priced alternative energy sources, which 
are preferred by some customers over electricity produced from coal, 
nuclear or natural gas plants, and customer usage of energy-efficient 
equipment that reduces energy demand;

• natural gas, crude oil and refined products production levels and prices;

• ability to procure satisfactory levels of inventory, such as coal, natural 

gas and uranium; and

• capacity and transmission service into, or out of, the Duke Energy 

Registrants’ markets.

Natural disasters or operational accidents may adversely affect the Duke 
Energy Registrants’ operating results.

Natural disasters or other operational accidents within the company 

or industry (such as forest fires, earthquakes, hurricanes or natural gas 
transmission pipeline explosions) could have direct or indirect impacts to 
the Duke Energy Registrants or to key contractors and suppliers. Further, the 
generation of electricity and the transportation and storage of natural gas 
involve inherent operating risks that may result in accidents involving serious 
injury or loss of life, environmental damage or property damage. Such events 
could impact the Duke Energy Registrants through changes to policies, laws 
and regulations whose compliance costs have a significant impact on the Duke 
Energy Registrants’ results of operations, financial position and cash flows. 
In addition, if a serious operational accident were to occur, existing insurance 
policies may not cover all of the potential exposures or the actual amount of 
loss incurred. Any losses not covered by insurance, or any increases in the cost 
of applicable insurance as a result of such accident, could have a material 
adverse effect on the results of operations, financial position, cash flows and 
reputation of the Duke Energy Registrants.

The reputation and financial condition of the Duke Energy Registrants 
could be negatively impacted due to their obligations to comply with 
federal and state regulations, laws, and other legal requirements that 
govern the operations, assessments, storage, closure, remediation, 
disposal and monitoring relating to CCR, the high costs and new 
rate impacts associated with implementing these new CCR-related 
requirements and the strategies and methods necessary to implement 
these requirements in compliance with these legal obligations.

As a result of electricity produced for decades at coal-fired power plants, 

the Duke Energy Registrants manage large amounts of CCR that are primarily 
stored in dry storage within landfills or combined with water in other surface 
impoundments, all in compliance with applicable regulatory requirements. A 
CCR-related operational incident could have a material adverse impact on the 
reputation and results of operations, financial position and cash flows of the 
Duke Energy Registrants.

During 2015, EPA regulations were enacted related to the management 
of CCR from power plants. These regulations classify CCR as nonhazardous 
waste under the RCRA and apply to electric generating sites with new 
and existing landfills and, new and existing surface impoundments, and 
establish requirements regarding landfill design, structural integrity design 
and assessment criteria for surface impoundments, groundwater monitoring, 
protection and remedial procedures and other operational and reporting 
procedures for the disposal and management of CCR. In addition to the 
federal regulations, CCR landfills and surface impoundments will continue 
to be regulated by existing state laws, regulations and permits, as well as 
additional legal requirements that may be imposed in the future, such as the 
settlement reached with the NCDEQ to excavate seven of the nine remaining 
coal ash basins in North Carolina, and partially excavate the remaining two. 
These federal and state laws, regulations and other legal requirements may 
require or result in additional expenditures, including increased operating and 
maintenance costs, which could affect the results of operations, financial 
position and cash flows of the Duke Energy Registrants. The Duke Energy 
Registrants will continue to seek full cost recovery for expenditures through the 
normal ratemaking process with state and federal utility commissions, who 

18

PART Ipermit recovery in rates of necessary and prudently incurred costs associated 
with the Duke Energy Registrants’ regulated operations, and through other 
wholesale contracts with terms that contemplate recovery of such costs, 
although there is no guarantee of full cost recovery. In addition, the timing for 
and amount of recovery of such costs could have a material adverse impact on 
Duke Energy’s cash flows.

The Duke Energy Registrants have recognized significant AROs related to 

these CCR-related requirements. Closure activities began in 2015 at the four 
sites specified as high-priority by the Coal Ash Act and at the W.S. Lee Steam 
Station site in South Carolina in connection with other legal requirements. 
Excavation at these sites involves movement of CCR materials to off-site 
locations for use as structural fill, to appropriate engineered off-site or on-site 
lined landfills or conversion of the ash for beneficial use. Duke Energy has 
completed excavation of coal ash regulated by the Coal Ash Act at three of the 
four high priority sites. At other sites, planning and closure methods have been 
studied and factored into the estimated retirement and management costs, 
and closure activities have commenced. As the closure and CCR management 
work progresses and final closure plans and corrective action measures are 
developed and approved at each site, the scope and complexity of work and the 
amount of CCR material could be greater than estimates and could, therefore, 
materially increase compliance expenditures and rate impacts.

The Duke Energy Registrants’ results of operations, financial position and 
cash flows may be negatively affected by a lack of growth or slower growth 
in the number of customers, or decline in customer demand or number of 
customers.

Growth in customer accounts and growth of customer usage each directly 

influence demand for electricity and natural gas and the need for additional 
power generation and delivery facilities. Customer growth and customer 
usage are affected by several factors outside the control of the Duke Energy 
Registrants, such as mandated EE measures, demand-side management goals, 
distributed generation resources and economic and demographic conditions, 
such as population changes, job and income growth, housing starts, new 
business formation and the overall level of economic activity.

Certain regulatory and legislative bodies have introduced or are 
considering requirements and/or incentives to reduce energy consumption 
by certain dates. Additionally, technological advances driven by federal laws 
mandating new levels of EE in end-use electric devices or other improvements 
in or applications of technology could lead to declines in per capita energy 
consumption.

Advances in distributed generation technologies that produce power, 

including fuel cells, microturbines, wind turbines and solar cells, may reduce 
the cost of alternative methods of producing power to a level competitive with 
central power station electric production utilized by the Duke Energy Registrants.

Some or all of these factors could result in a lack of growth or decline in 

customer demand for electricity or number of customers and may cause the 
failure of the Duke Energy Registrants to fully realize anticipated benefits from 
significant capital investments and expenditures, which could have a material 
adverse effect on their results of operations, financial position and cash flows.

Furthermore, the Duke Energy Registrants currently have EE riders in place 

to recover the cost of EE programs in North Carolina, South Carolina, Florida, 
Indiana, Ohio and Kentucky. Should the Duke Energy Registrants be required 
to invest in conservation measures that result in reduced sales from effective 
conservation, regulatory lag in adjusting rates for the impact of these measures 
could have a negative financial impact.

The Duke Energy Registrants’ operating results may fluctuate on a 
seasonal and quarterly basis and can be negatively affected by changes 
in weather conditions and severe weather, including extreme weather 
conditions associated with climate change.

Electric power generation and natural gas distribution are generally 
seasonal businesses. In most parts of the U.S., the demand for power peaks 
during the warmer summer months, with market prices also typically peaking at 
that time. In other areas, demand for power peaks during the winter. Demand for 
natural gas peaks during the winter months. Further, extreme weather conditions 
such as hurricanes, droughts, heat waves, winter storms and severe weather 
associated with climate change could cause these seasonal fluctuations to be 
more pronounced. As a result, the overall operating results of the Duke Energy 
Registrants’ businesses may fluctuate substantially on a seasonal and quarterly 
basis and thus make period-to-period comparison less relevant.

Sustained severe drought conditions could impact generation by 
hydroelectric plants, as well as fossil and nuclear plant operations, as these 
facilities use water for cooling purposes and for the operation of environmental 
compliance equipment. Furthermore, destruction caused by severe weather 
events, such as hurricanes, tornadoes, severe thunderstorms, snow and ice 
storms, can result in lost operating revenues due to outages, property damage, 
including downed transmission and distribution lines, and additional and 
unexpected expenses to mitigate storm damage. The cost of storm restoration 
efforts may not be fully recoverable through the regulatory process.

The Duke Energy Registrants’ sales may decrease if they are unable to gain 
adequate, reliable and affordable access to transmission assets.

The Duke Energy Registrants depend on transmission and distribution 
facilities owned and operated by utilities and other energy companies to deliver 
electricity sold to the wholesale market. The FERC’s power transmission 
regulations require wholesale electric transmission services to be offered on 
an open-access, non-discriminatory basis. If transmission is disrupted, or if 
transmission capacity is inadequate, the Duke Energy Registrants’ ability to sell 
and deliver products may be hindered.

The different regional power markets have changing regulatory structures, 

which could affect growth and performance in these regions. In addition, the 
ISOs who oversee the transmission systems in regional power markets have 
imposed in the past, and may impose in the future, price limitations and other 
mechanisms to address volatility in the power markets. These types of price 
limitations and other mechanisms may adversely impact the profitability of the 
Duke Energy Registrants’ wholesale power marketing business.

Duke Energy may be unable to complete necessary or desirable pipeline 
expansion or infrastructure development or maintenance projects, which 
may prevent the Duke Energy Registrants from expanding the natural gas 
business.

In order to serve current or new natural gas customers or expand the 

service to existing customers, the Duke Energy Registrants need to maintain, 
expand or upgrade distribution, transmission and/or storage infrastructure, 
including laying new pipeline and building compressor stations. Duke Energy 
Registrants have made significant investments in pipeline development projects, 
which are being operated and constructed by third-party joint venture partners. 
The Duke Energy Registrants must rely on their third-party joint venture 
partners for proper construction management of the projects and are dependent 
upon contractors for the successful and timely completion of the projects. 
In addition, various factors, such as the inability to obtain required approval 
from local, state and/or federal regulatory and governmental bodies, public 
opposition to projects, adverse litigation rulings, inability to obtain adequate 
financing, competition for labor and materials, construction delays, cost 
overruns and the inability to negotiate acceptable agreements relating to rights 
of way, construction or other material development components, may prevent or 
delay the completion of projects or materially increase the cost of such projects, 
which could have a material adverse effect on the results of operations and 
financial position of Duke Energy.

19

PART IThe availability of adequate interstate pipeline transportation capacity and 
natural gas supply may decrease.

basis threat requirements. These increased costs could include additional 
physical plant security and security personnel or additional capability following 
a terrorist incident.

The Duke Energy Registrants purchase almost all of their natural gas 
supply from interstate sources that must be transported to the applicable 
service territories. Interstate pipeline companies transport the natural gas to 
the Duke Energy Registrants’ systems under firm service agreements that are 
designed to meet the requirements of their core markets. A significant disruption 
to interstate pipelines capacity or reduction in natural gas supply due to events 
including, but not limited to, operational failures or disruptions, hurricanes, 
tornadoes, floods, freeze off of natural gas wells, terrorist or cyberattacks or 
other acts of war or legislative or regulatory actions or requirements, including 
remediation related to integrity inspections, could reduce the normal interstate 
supply of natural gas and thereby reduce earnings. Moreover, if additional 
natural gas infrastructure, including, but not limited to, exploration and drilling 
rigs and platforms, processing and gathering systems, off-shore pipelines, 
interstate pipelines and storage, cannot be built at a pace that meets demand, 
then growth opportunities could be limited.

Fluctuations in commodity prices or availability may adversely affect 
various aspects of the Duke Energy Registrants’ operations as well as their 
results of operations, financial position and cash flows.

The Duke Energy Registrants are exposed to the effects of market 
fluctuations in the price of natural gas, coal, fuel oil, nuclear fuel, electricity 
and other energy-related commodities as a result of their ownership of 
energy-related assets. Fuel costs are recovered primarily through cost-recovery 
clauses, subject to the approval of state utility commissions.

Additionally, the Duke Energy Registrants are exposed to risk that 

counterparties will not be able to fulfill their obligations. Disruption in the 
delivery of fuel, including disruptions as a result of, among other things, 
transportation delays, weather, labor relations, force majeure events or 
environmental regulations affecting any of these fuel suppliers, could limit the 
Duke Energy Registrants’ ability to operate their facilities. Should counterparties 
fail to perform, the Duke Energy Registrants might be forced to replace the 
underlying commitment at prevailing market prices possibly resulting in losses 
in addition to the amounts, if any, already paid to the counterparties.

Certain of the Duke Energy Registrants’ hedge agreements may result in 

the receipt of, or posting of, collateral with counterparties, depending on the 
daily market-based calculation of financial exposure of the derivative positions. 
Fluctuations in commodity prices that lead to the return of collateral received 
and/or the posting of collateral with counterparties could negatively impact 
liquidity. Downgrades in the Duke Energy Registrants’ credit ratings could lead 
to additional collateral posting requirements. The Duke Energy Registrants 
continually monitor derivative positions in relation to market price activity.

Potential terrorist activities, or military or other actions, could adversely 
affect the Duke Energy Registrants’ businesses.

The continued threat of terrorism and the impact of retaliatory military 

and other action by the U.S. and its allies may lead to increased political, 
economic and financial market instability and volatility in prices for natural 
gas and oil, which may have material adverse effects in ways the Duke Energy 
Registrants cannot predict at this time. In addition, future acts of terrorism and 
possible reprisals as a consequence of action by the U.S. and its allies could 
be directed against companies operating in the U.S. Information technology 
systems, transmission and distribution and generation facilities such as nuclear 
plants could be potential targets of terrorist activities or harmful activities 
by individuals or groups that could have a material adverse effect on Duke 
Energy Registrants’ businesses. In particular, the Duke Energy Registrants 
may experience increased capital and operating costs to implement increased 
security for their information technology systems, transmission and distribution 
and generation facilities, including nuclear power plants under the NRC’s design 

The failure of Duke Energy information technology systems, or the failure 
to enhance existing information technology systems and implement 
new technology, could adversely affect the Duke Energy Registrants’ 
businesses.

Duke Energy’s operations are dependent upon the proper functioning of its 
internal systems, including the information technology systems that support our 
underlying business processes. Any significant failure or malfunction of such 
information technology systems may result in disruptions of our operations. In 
the ordinary course of business, we rely on information technology systems, 
including the internet and third-party hosted services, to support a variety 
of business processes and activities and to store sensitive data, including 
(i) intellectual property, (ii) proprietary business information, (iii) personally 
identifiable information of our customers, employees, retirees and shareholders 
and (iv) data with respect to invoicing and the collection of payments, 
accounting, procurement, and supply chain activities. Our information 
technology systems are dependent upon global communications and cloud 
service providers, as well as their respective vendors, many of whom have at 
some point experienced significant system failures and outages in the past 
and may experience such failures and outages in the future. These providers’ 
systems are susceptible to cybersecurity and data breaches, outages from fire, 
floods, power loss, telecommunications failures, break-ins and similar events. 
Failure to prevent or mitigate data loss from system failures or outages could 
materially affect the results of operations, financial position and cash flows of 
the Duke Energy Registrants.

In addition to maintaining our current information technology systems, 

Duke Energy believes the digital transformation of its business is key to 
driving internal efficiencies as well as providing additional capabilities 
to customers. Duke Energy’s information technology systems are critical to 
cost-effective, reliable daily operations and our ability to effectively serve our 
customers. We expect our customers to continue to demand more sophisticated 
technology-driven solutions and we must enhance or replace our information 
technology systems in response. This involves significant development and 
implementation costs to keep pace with changing technologies and customer 
demand. If we fail to successfully implement critical technology, or if it does not 
provide the anticipated benefits or meet customer demands, such failure could 
materially adversely affect our business strategy as well as impact the results 
of operations, financial position and cash flows of the Duke Energy Registrants.

Cyberattacks and data security breaches could adversely affect the Duke 
Energy Registrants’ businesses.

Cybersecurity risks have increased in recent years as a result of the 
proliferation of new technologies and the increased sophistication, magnitude 
and frequency of cyberattacks and data security breaches. Duke Energy relies 
on the continued operation of sophisticated digital information technology 
systems and network infrastructure, which are part of an interconnected 
regional grid. Additionally, connectivity to the internet continues to increase 
through grid modernization and other operational excellence initiatives. Because 
of the critical nature of the infrastructure, increased connectivity to the internet 
and technology systems’ inherent vulnerability to disability or failures due 
to hacking, viruses, acts of war or terrorism or other types of data security 
breaches, the Duke Energy Registrants face a heightened risk of cyberattack 
from foreign or domestic sources and have been subject, and will likely continue 
to be subject, to attempts to gain unauthorized access to information and/or 
information systems or to disrupt utility operations through computer viruses 
and phishing attempts either directly or indirectly through its material vendors 
or related third parties. In the event of a significant cybersecurity breach on 
either the Duke Energy Registrants or with one of our material vendors or related 

20

PART Ithird parties, the Duke Energy Registrants could (i) have business operations 
disrupted, including the disruption of the operation of our assets and the power 
grid, theft of confidential company, employee, retiree, shareholder, vendor or 
customer information, and general business systems and process interruption 
or compromise, including preventing the Duke Energy Registrants from servicing 
customers, collecting revenues or the recording, processing and/or reporting 
financial information correctly, (ii) experience substantial loss of revenues, 
repair and restoration costs, penalties and costs for lack of compliance with 
relevant regulations, implementation costs for additional security measures to 
avert future cyberattacks and other financial loss and (iii) be subject to increased 
regulation, litigation and reputational damage. While Duke Energy maintains 
insurance relating to cybersecurity events, such insurance is subject to a number 
of exclusions and may be insufficient to offset any losses, costs or damage 
experienced. Also, the market for cybersecurity insurance is relatively new and 
coverage available for cybersecurity events is evolving as the industry matures.

The Duke Energy Registrants are subject to standards enacted by the 
North American Electric Reliability Corporation and enforced by FERC regarding 
protection of the physical and cyber security of critical infrastructure assets 
required for operating North America’s bulk electric system. The Duke Energy 
Registrants are also subject to regulations set by the Nuclear Regulatory 
Commission regarding the protection of digital computer and communication 
systems and networks required for the operation of nuclear power plants. 
While the Duke Energy Registrants believe they are in compliance with such 
standards and regulations, the Duke Energy Registrants have from time to time 
been, and may in the future be, found to be in violation of such standards and 
regulations. In addition, compliance with or changes in the applicable standards 
and regulations may subject the Duke Energy Registrants to higher operating 
costs and/or increased capital expenditures as well as substantial fines for 
non-compliance.

Failure to attract and retain an appropriately qualified workforce could 
unfavorably impact the Duke Energy Registrants’ results of operations.

Certain events, such as an aging workforce, mismatch of skill set or 

complement to future needs, or unavailability of contract resources may lead 
to operating challenges and increased costs. The challenges include lack 
of resources, loss of knowledge base and the lengthy time required for skill 
development. In this case, costs, including costs for contractors to replace 
employees, productivity costs and safety costs, may increase. Failure to hire and 
adequately train replacement employees, including the transfer of significant 
internal historical knowledge and expertise to new employees, or future 
availability and cost of contract labor may adversely affect the ability to manage 
and operate the business, especially considering the workforce needs associated 
with nuclear generation facilities and new skills required to operate a modernized, 
technology-enabled power grid. If the Duke Energy Registrants are unable to 
successfully attract and retain an appropriately qualified workforce, their results 
of operations, financial position and cash flows could be negatively affected.

Duke Energy Ohio’s and Duke Energy Indiana’s membership in an RTO 
presents risks that could have a material adverse effect on their results of 
operations, financial position and cash flows.

The rules governing the various regional power markets may change, 
which could affect Duke Energy Ohio’s and Duke Energy Indiana’s costs and/or 
revenues. To the degree Duke Energy Ohio and Duke Energy Indiana incur 
significant additional fees and increased costs to participate in an RTO, their 
results of operations may be impacted. Duke Energy Ohio and Duke Energy 
Indiana may be allocated a portion of the cost of transmission facilities built 
by others due to changes in RTO transmission rate design. Duke Energy Ohio 
and Duke Energy Indiana may be required to expand their transmission system 
according to decisions made by an RTO rather than their own internal planning 
process. In addition, RTOs have been developing rules associated with the 
allocation and methodology of assigning costs associated with improved 

transmission reliability, reduced transmission congestion and firm transmission 
rights that may have a financial impact on the results of operations, financial 
position and cash flows of Duke Energy Ohio and Duke Energy Indiana.

As members of an RTO, Duke Energy Ohio and Duke Energy Indiana are 
subject to certain additional risks, including those associated with the allocation 
among RTO members, of losses caused by unreimbursed defaults of other 
participants in the RTO markets and those associated with complaint cases filed 
against an RTO that may seek refunds of revenues previously earned by RTO 
members.

The Duke Energy Registrants may not recover costs incurred to begin 
construction on projects that are canceled.

Duke Energy’s long-term strategy requires the construction of new 

projects, either wholly owned or partially owned, which involve a number of 
risks, including construction delays, nonperformance by equipment and other 
third-party suppliers, and increases in equipment and labor costs. To limit the 
risks of these construction projects, the Duke Energy Registrants enter into 
equipment purchase orders and construction contracts and incur engineering 
and design service costs in advance of receiving necessary regulatory approvals 
and/or siting or environmental permits. If any of these projects are canceled for 
any reason, including failure to receive necessary regulatory approvals and/or 
siting or environmental permits, significant cancellation penalties under the 
equipment purchase orders and construction contracts could occur. In addition, 
if any construction work or investments have been recorded as an asset, an 
impairment may need to be recorded in the event the project is canceled.

The Duke Energy Registrants are subject to risks associated with their 
ability to obtain adequate insurance at acceptable costs.

The financial condition of some insurance companies, actual or 

threatened physical or cyber attacks, and natural disasters, among other things, 
could have disruptive effects on insurance markets. The availability of insurance 
covering risks that the Duke Energy Registrants and their respective competitors 
typically insure against may decrease, and the insurance that the Duke Energy 
Registrants are able to obtain may have higher deductibles, higher premiums, 
and more restrictive policy terms. Further, the insurance policies may not cover 
all of the potential exposures or the actual amount of loss incurred. Any losses 
not covered by insurance, or any increases in the cost of applicable insurance, 
could adversely affect the results of operations, financial position or cash flows 
of the affected Duke Energy Registrant.

NUCLEAR GENERATION RISKS

Duke Energy Carolinas, Duke Energy Progress and Duke Energy Florida 
may incur substantial costs and liabilities due to their ownership and 
operation of nuclear generating facilities.

Ownership interests in and operation of nuclear stations by Duke Energy 
Carolinas, Duke Energy Progress and Duke Energy Florida subject them to various 
risks. These risks include, among other things: the potential harmful effects on 
the environment and human health resulting from the current or past operation 
of nuclear facilities and the storage, handling and disposal of radioactive 
materials; limitations on the amounts and types of insurance commercially 
available to cover losses that might arise in connection with nuclear operations; 
and uncertainties with respect to the technological and financial aspects of 
decommissioning nuclear plants at the end of their licensed lives.

Ownership and operation of nuclear generation facilities requires 

compliance with licensing and safety-related requirements imposed by the NRC. 
In the event of non-compliance, the NRC may increase regulatory oversight, 
impose fines or shut down a unit depending upon its assessment of the severity 
of the situation. Revised security and safety requirements promulgated by 

21

PART Ithe NRC, which could be prompted by, among other things, events within or 
outside of the control of Duke Energy Carolinas, Duke Energy Progress and Duke 
Energy Florida, such as a serious nuclear incident at a facility owned by a third 
party, could necessitate substantial capital and other expenditures, as well as 
assessments to cover third-party losses. In addition, if a serious nuclear incident 
were to occur, it could have a material adverse effect on the results of operations, 
financial position, cash flows and reputation of the Duke Energy Registrants.

LIQUIDITY, CAPITAL REQUIREMENTS AND COMMON STOCK RISKS

The Duke Energy Registrants rely on access to short-term borrowings and 
longer-term debt and equity markets to finance their capital requirements 
and support their liquidity needs. Access to those markets can be 
adversely affected by a number of conditions, many of which are beyond 
the Duke Energy Registrants’ control.

The Duke Energy Registrants’ businesses are significantly financed 

through issuances of debt and equity. The maturity and repayment profile of 
debt used to finance investments often does not correlate to cash flows from 
their assets. Accordingly, as a source of liquidity for capital requirements not 
satisfied by the cash flows from their operations and to fund investments 
originally financed through debt instruments with disparate maturities, the 
Duke Energy Registrants rely on access to short-term money markets as well as 
longer-term capital markets. The Subsidiary Registrants also rely on access to 
short-term intercompany borrowings. If the Duke Energy Registrants are not able 
to access debt or equity at competitive rates or at all, the ability to finance their 
operations and implement their strategy and business plan as scheduled could 
be adversely affected. An inability to access debt and equity may limit the Duke 
Energy Registrants’ ability to pursue improvements or acquisitions that they 
may otherwise rely on for future growth.

Market disruptions may increase the cost of borrowing or adversely affect 

the ability to access one or more financial markets. Such disruptions could 
include: economic downturns, the bankruptcy of an unrelated energy company, 
unfavorable capital market conditions, market prices for electricity and natural 
gas, actual or threatened terrorist attacks, or the overall health of the energy 
industry. The availability of credit under Duke Energy’s Master Credit Facility 
depends upon the ability of the banks providing commitments under the facility 
to provide funds when their obligations to do so arise. Systematic risk of the 
banking system and the financial markets could prevent a bank from meeting its 
obligations under the facility agreement.

Duke Energy maintains a revolving credit facility to provide backup for its 
commercial paper program and letters of credit to support variable rate demand 
tax-exempt bonds that may be put to the Duke Energy Registrant issuer at 
the option of the holder. The facility includes borrowing sublimits for the Duke 
Energy Registrants, each of whom is a party to the credit facility, and financial 
covenants that limit the amount of debt that can be outstanding as a percentage 
of the total capital for the specific entity. Failure to maintain these covenants at 
a particular entity could preclude Duke Energy from issuing commercial paper or 
the Duke Energy Registrants from issuing letters of credit or borrowing under the 
Master Credit Facility.

The Duke Energy Registrants must meet credit quality standards and 
there is no assurance they will maintain investment grade credit ratings. 
If the Duke Energy Registrants are unable to maintain investment grade 
credit ratings, they would be required under credit agreements to provide 
collateral in the form of letters of credit or cash, which may materially 
adversely affect their liquidity.

Each of the Duke Energy Registrants’ senior long-term debt issuances is 
currently rated investment grade by various rating agencies. The Duke Energy 
Registrants cannot ensure their senior long-term debt will be rated investment 
grade in the future.

22

If the rating agencies were to rate the Duke Energy Registrants below 

investment grade, borrowing costs would increase, perhaps significantly. 
In addition, the potential pool of investors and funding sources would likely 
decrease. Further, if the short-term debt rating were to fall, access to the 
commercial paper market could be significantly limited.

A downgrade below investment grade could also require the posting of 

additional collateral in the form of letters of credit or cash under various credit, 
commodity and capacity agreements and trigger termination clauses in some 
interest rate derivative agreements, which would require cash payments. All 
of these events would likely reduce the Duke Energy Registrants’ liquidity and 
profitability and could have a material effect on their results of operations, 
financial position and cash flows.

Non-compliance with debt covenants or conditions could adversely affect 
the Duke Energy Registrants’ ability to execute future borrowings.

The Duke Energy Registrants’ debt and credit agreements contain 
various financial and other covenants. Failure to meet those covenants 
beyond applicable grace periods could result in accelerated due dates and/or 
termination of the agreements.

Market performance and other changes may decrease the value of the 
NDTF investments of Duke Energy Carolinas, Duke Energy Progress and 
Duke Energy Florida, which then could require significant additional 
funding.

Ownership and operation of nuclear generation facilities also requires the 
maintenance of funded trusts that are intended to pay for the decommissioning 
costs of the respective nuclear power plants. The performance of the capital 
markets affects the values of the assets held in trust to satisfy these future 
obligations. Duke Energy Carolinas, Duke Energy Progress and Duke Energy Florida 
have significant obligations in this area and hold significant assets in these trusts. 
These assets are subject to market fluctuations and will yield uncertain returns, 
which may fall below projected rates of return. Although a number of factors 
impact funding requirements, a decline in the market value of the assets may 
increase the funding requirements of the obligations for decommissioning nuclear 
plants. If Duke Energy Carolinas, Duke Energy Progress and Duke Energy Florida 
are unable to successfully manage their NDTF assets, their results of operations, 
financial position and cash flows could be negatively affected.

Poor investment performance of the Duke Energy pension plan holdings 
and other factors impacting pension plan costs could unfavorably impact 
the Duke Energy Registrants’ liquidity and results of operations.

The costs of providing non-contributory defined benefit pension plans 
are dependent upon a number of factors, such as the rates of return on plan 
assets, discount rates, the level of interest rates used to measure the required 
minimum funding levels of the plans, future government regulation and required 
or voluntary contributions made to the plans. The Subsidiary Registrants 
are allocated their proportionate share of the cost and obligations related to 
these plans. Without sustained growth in the pension investments over time 
to increase the value of plan assets and, depending upon the other factors 
impacting costs as listed above, Duke Energy could be required to fund its 
plans with significant amounts of cash. Such cash funding obligations, and the 
Subsidiary Registrants’ proportionate share of such cash funding obligations, 
could have a material impact on the Duke Energy Registrants’ results of 
operations, financial position and cash flows.

PART IDuke Energy is a holding company and depends on the cash flows from its 
subsidiaries to meet its financial obligations.

Because Duke Energy is a holding company with no operations or cash 
flows of its own, its ability to meet its financial obligations, including making 
interest and principal payments on outstanding indebtedness and to pay 
dividends on its common stock, is primarily dependent on the net income 
and cash flows of its subsidiaries and the ability of those subsidiaries to pay 

upstream dividends or to repay borrowed funds. Prior to funding Duke Energy, its 
subsidiaries have regulatory restrictions and financial obligations that must be 
satisfied. These subsidiaries are separate legal entities and have no obligation 
to provide Duke Energy with funds. In addition, Duke Energy may provide capital 
contributions or debt financing to its subsidiaries under certain circumstances, 
which would reduce the funds available to meet its financial obligations, 
including making interest and principal payments on outstanding indebtedness 
and to pay dividends on Duke Energy’s common stock.

MTBE Litigation

On December 15, 2017, the state of Maryland filed suit in Baltimore City Circuit Court against Duke Energy Merchants and other defendants alleging 

contamination of state waters by MTBE leaking from gasoline storage tanks. MTBE is a gasoline additive intended to increase the oxygen levels in gasoline and make 
it burn cleaner. The case was removed from Baltimore City Circuit Court to federal District Court. Initial motions to dismiss filed by the defendants were denied by the 
court on September 4, 2019. The defendants have filed answers and will pursue summary judgment after the completion of discovery. Duke Energy cannot predict the 
outcome of this matter.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Management’s Discussion and Analysis includes financial information 
prepared in accordance with GAAP in the U.S., as well as certain non-GAAP 
financial measures such as adjusted earnings and adjusted EPS discussed 
below. Generally, a non-GAAP financial measure is a numerical measure 
of financial performance, financial position or cash flows that excludes (or 
includes) amounts that are included in (or excluded from) the most directly 
comparable measure calculated and presented in accordance with GAAP. The 
non-GAAP financial measures should be viewed as a supplement to, and 
not a substitute for, financial measures presented in accordance with GAAP. 
Non-GAAP measures as presented herein may not be comparable to similarly 
titled measures used by other companies.

The following combined Management’s Discussion and Analysis of 
Financial Condition and Results of Operations is separately filed by Duke Energy 
Corporation and its subsidiaries. Duke Energy Carolinas, LLC, Progress Energy, 
Inc., Duke Energy Progress, LLC, Duke Energy Florida, LLC, Duke Energy Ohio, 
Inc., Duke Energy Indiana, LLC and Piedmont Natural Gas Company, Inc.. 
However, none of the registrants make any representation as to information 
related solely to Duke Energy or the subsidiary registrants of Duke Energy other 
than itself.

Management’s Discussion and Analysis should be read in conjunction 

with the Consolidated Financial Statements and Notes for the years ended 
December 31, 2019, 2018 and 2017.

See “Item 7. Management’s Discussion and Analysis of Financial 
Condition and Results of Operations,” in Duke Energy’s Annual Report on 
Form 10-K for the year ended December 31, 2018, filed with the SEC on 
February 28, 2019, for a discussion of variance drivers for the year ended 
December 31, 2018, as compared to December 31, 2017.

DUKE ENERGY

Duke Energy is an energy company headquartered in Charlotte,  
North Carolina. Duke Energy operates in the U.S. primarily through its wholly 
owned subsidiaries, Duke Energy Carolinas, Duke Energy Progress, Duke Energy 
Florida, Duke Energy Ohio, Duke Energy Indiana and Piedmont. When discussing 
Duke Energy’s consolidated financial information, it necessarily includes 
the results of the Subsidiary Registrants, which along with Duke Energy, are 
collectively referred to as the Duke Energy Registrants.

Executive Overview

At Duke Energy the fundamentals of our business are strong and allow 
us to deliver growth in earnings and dividends in a low-risk, predictable and 
transparent way. In 2019, we met our near-term financial commitments and 
positioned the company for sustainable long-term growth. We are focused on 
a business portfolio that will deliver a reliable dividend with 4% to 6% EPS 
growth through 2024. This growth is supported by our capital plan, timely 
cost-recovery mechanisms in most jurisdictions and our ability to manage our 
cost structure. The strength of our balance sheet is of vital importance to the 
cost-effective financing of our growth strategy, and in 2019 we continued to 
strengthen it by issuing $2 billion of preferred equity and $2.5 billion of common 
stock through a forward sales agreement which is expected to settle on or prior 
to December 31, 2020.

(a)  See Results of Operations below for Duke Energy’s definition of adjusted earnings and adjusted diluted EPS as well as a reconciliation of this non-GAAP financial measure to net income available to Duke Energy and net 

income available to Duke Energy per diluted share.

Duke Energy’s 2019 Net Income Available to Duke Energy Corporation 
(GAAP Reported Earnings) were impacted by: favorable rate case and rider 
recovery outcomes, net of regulatory lag, and ongoing cost management efforts 
in Electric Utilities and Infrastructure; improved margins and increased ACP 
investment in Gas Utilities and Infrastructure; and growth in project investments 
in Commercial Renewables. See “Results of Operations” below for a detailed 
discussion of the consolidated results of operations and a detailed discussion 
of financial results for each of Duke Energy’s reportable business segments, 
as well as Other where financing costs increased in 2019 to fund segment 
operations and other liquidity needs.

2019 Areas of Focus and Accomplishments

Operational Excellence, Safety and Reliability. The reliable and 

safe operation of our power plants, electric distribution system and natural 
gas infrastructure in our communities is foundational to our customers, our 
financial results and our credibility with stakeholders. Our regulated generation 
fleet performance was strong throughout the year. All of our nuclear sites have 
achieved the industry’s highest distinction rating. Our electric distribution 
system performed well throughout the year, with outage durations down when 
adjusted for storms. The safety of our workforce is a core value. Our employees 
delivered strong safety results in 2019, and we are at or near the top of our 
industry.

Storm Response and System Restoration. The 2019 Atlantic hurricane 

season was the fourth consecutive year of above-average damaging storms. 
Our ability to effectively handle all facets of the 2019 storm response efforts 
is a testament to our team’s extensive preparation and coordination, applying 
lessons learned from previous storms, and to on-the-ground management 
throughout the restoration efforts. Notably in 2019 Duke Energy earned EEI’s 
Emergency Recovery Award, our 22nd EEI award since 1998 and a strong 
affirmation of the work of our employees to support customers when they need 
us most.

Customer Satisfaction. Duke Energy continues to transform the customer 
experience through our use of customer data to better inform operational priorities 
and performance levels. This data-driven approach allows us to identify the 
investments that are the most important to the customer experience. In 2019, 
we instituted billing and payment-related communications and options, and we 
continue to enhance outage-related communications to customers.

Constructive Regulatory and Legislative Outcomes. One of our 
long-term strategic goals is to achieve modernized regulatory constructs in our 
jurisdictions. Modernized constructs provide benefits, which include improved 
earnings and cash flows through more timely recovery of investments, as well 
as stable pricing for customers. In 2019, Duke Energy, North Carolina regulators 
and environmentalists reached an agreement to permanently close all remaining 
coal ash basins in North Carolina. This agreement reduces the cost to close our 
coal ash basins for our Carolinas customers in comparison to the initial NCDEQ 
closure order. In 2019 we achieved constructive rate case outcomes driving 
earnings growth through rate base increases in South Carolina (electric), North 
Carolina (natural gas), Ohio (electric distribution) and Kentucky (natural gas). In 
addition, we have a multiyear rate plan in Florida and grid investment riders in 
the Midwest which enable more timely cost recovery and earnings growth.

Digital Transformation. Duke Energy has a demonstrated track record 

of driving efficiencies and productivity into the business. We continue to 
leverage new technology, digital tools and data analytics across the business in 
response to a transforming landscape. In 2019, we created a team dedicated 
to developing applications and other solutions to deliver productivity gains and 
improvements to the customer experience.

Modernizing the Power Grid. Our grid improvement programs continue 

to be a key component of our growth strategy. Modernization of the electric 
grid, including smart meters, storm hardening, self-healing and targeted 
undergrounding helps to ensure the system is better prepared for severe 
weather, improves the system’s reliability and flexibility, and provides better 
information and services for customers. In 2019, 79% of our jurisdictions were 
equipped with smart meters and we remain on track to be fully deployed across 
all regions by 2021. We continue to expand our self-optimizing grid capabilities, 
and in 2019 that saved over a half million customer interruptions.

Generating Cleaner Energy. Overall, we have lowered our carbon 
emissions by 39% since 2005, consistent with our new goal to reduce carbon 
emissions by at least 50% by 2030 and to achieve net-zero carbon emissions 
by 2050. Our commitment for 2030 includes retiring plants, operating our 
existing carbon-free resources and investing in natural gas infrastructure, 
renewables and our energy delivery system. As we look beyond 2030, we will 
need additional tools to continue our progress. We will work actively to advocate 
for research and development of carbon-free, dispatchable resources. That 
includes longer-term energy storage, advanced nuclear technologies, carbon 
capture and zero-carbon fuels.

30

PART IIExpanding the Natural Gas Platform. We continue to pursue 
natural gas infrastructure investments. While the judicial and administrative 
challenges to date have been substantial, we are committed to the 
construction of the ACP pipeline to bring low-cost gas supply and economic 
development opportunities to the Southeast U.S. Construction is underway 
on a liquefied natural gas facility in Robeson County, North Carolina, on 
property Piedmont owns. This investment will help Piedmont provide a 
reliable gas supply to customers during peak usage periods and protect 
customers from price volatility when there is a higher-than-normal demand 
for natural gas.

Dividend Growth. In 2019, Duke Energy continued to grow the dividend 

payment to shareholders. 2019 represented the 93rd consecutive year Duke 
Energy paid a cash dividend on its common stock.

Duke Energy Objectives – 2020 and Beyond

Duke Energy will continue to deliver exceptional value to customers, 

be an integral part of the communities in which we do business and provide 
attractive returns to investors. We have an achievable, long-term strategy 
in place, and it is producing tangible results, yet the industry in which we 
operate is becoming more and more dynamic. We are adjusting, where 
necessary, and accelerating our focus in key areas to ensure the company is 
well positioned to be successful for many decades into the future. As we look 
ahead to 2020, our plans include:

• Continuing to place the customer at the center of all that we do which 

includes providing customized products and solutions

• Strengthening our relationships with all our vast stakeholders in the 

communities in which we operate and invest

• Generating cleaner energy and working to achieve net-zero carbon 

emissions by 2050

• Maintaining the safety of our communities and employees

• Modernizing and strengthening the energy grid

• Expanding the natural gas infrastructure

• Deploying digital tools across our business

Results of Operations

Non-GAAP Measures

Management evaluates financial performance in part based on non-GAAP 

financial measures, including adjusted earnings and adjusted diluted EPS. 
These items represent income from continuing operations available to Duke 
Energy common stockholders in dollar and per-share amounts, adjusted for 
the dollar and per-share impact of special items. As discussed below, special 
items include certain charges and credits, which management believes are 
not indicative of Duke Energy’s ongoing performance. Management believes 
the presentation of adjusted earnings and adjusted diluted EPS provides 
useful information to investors, as it provides them with an additional relevant 
comparison of Duke Energy’s performance across periods.

Management uses these non-GAAP financial measures for planning 

and forecasting, and for reporting financial results to the Board of Directors, 
employees, stockholders, analysts and investors. Adjusted diluted EPS is also 
used as a basis for employee incentive bonuses. The most directly comparable 
GAAP measures for adjusted earnings and adjusted diluted EPS are GAAP 
Reported Earnings and Diluted EPS Available to Duke Energy Corporation 
common stockholders (GAAP Reported EPS), respectively.

Special items included in the periods presented include the following, 

which management believes do not reflect ongoing costs:

• Impairment Charges in 2019 represents a reduction of a prior year 
impairment at Citrus County CC and an OTTI on the remaining 
investment in Constitution. For 2018, it represents an impairment at 
Citrus County CC, a goodwill impairment at Commercial Renewables 
and an OTTI of an investment in Constitution. 

• Costs to Achieve Mergers represents charges that result from strategic 

acquisitions.

• Regulatory and Legislative Impacts in 2018 represents charges related 
to the Duke Energy Progress and Duke Energy Carolinas North Carolina 
rate case orders and the repeal of the South Carolina Base Load Review 
Act.

• Sale of Retired Plant represents the loss associated with selling 

Beckjord, a nonregulated generating facility in Ohio.

• Impacts of the Tax Act represents amounts recognized related to the 

Tax Act.

• Severance Charges relate to companywide initiatives, excluding merger 
integration, to standardize processes and systems, leverage technology 
and workforce optimization.

Duke Energy’s adjusted earnings and adjusted diluted EPS may not be 
comparable to similarly titled measures of another company because other 
companies may not calculate the measures in the same manner.

liabilities at the lower rate at December 31, 2017. For Duke Energy’s regulated operations, where the reduction in the net accumulated deferred income tax liability is expected to be returned to customers in future rates, the 
remeasurement has been deferred as a regulatory liability. This amount represents a true up of existing regulatory liabilities related to the Tax Act. See Note 24 to the Consolidated Financial Statements, “Income Taxes” for 
more information.

(f)  Net of tax benefit of $43 million.

Year Ended December 31, 2019, as compared to 2018

SEGMENT RESULTS

GAAP Reported EPS was $5.06 for the year ended December 31, 2019, 

compared to $3.76 for the year ended December 31, 2018. The increase in 
GAAP Reported earnings was primarily due to current year favorable rate case 
and rider recovery outcomes, an adjustment related to income tax recognition 
for equity method investments, growth in Commercial Renewables from new 
solar farms commencing commercial operations and prior year regulatory and 
legislative impacts, impairments, severance, loss on sale of a retired plant 
and costs to achieve merger. This favorability was partially offset by higher 
depreciation and higher financing costs in the current year. The equity method 
investment adjustment was immaterial and relates to prior years.

As discussed and shown in the table above, management also evaluates 
financial performance based on adjusted diluted EPS. Duke Energy’s adjusted 
diluted EPS was $5.06 for the year ended December 31, 2019, compared to 
$4.72 for the year ended December 31, 2018.

The remaining information presented in this discussion of results of 
operations is on a GAAP basis. Management evaluates segment performance 
based on segment income. Segment income is defined as income from 
continuing operations net of income attributable to noncontrolling interests and 
preferred stock dividends. Segment income includes intercompany revenues and 
expenses that are eliminated in the Consolidated Financial Statements.

Duke Energy’s segment structure includes the following segments: Electric 

Utilities and Infrastructure, Gas Utilities and Infrastructure and Commercial 
Renewables. The remainder of Duke Energy’s operations is presented as Other. 
See Note 3 to the Consolidated Financial Statements, “Business Segments,” for 
additional information on Duke Energy’s segment structure.

Year Ended December 31, 2019, as compared to 2018

Electric Utilities and Infrastructure’s results were impacted by positive 
contributions from the Duke Energy Carolinas and Duke Energy Progress North 
Carolina and South Carolina rate cases and Duke Energy Florida’s base rate 
adjustments due to the Citrus County CC being placed in service. These drivers 
were partially offset by higher depreciation from a growing asset base and 
higher interest expense. The following is a detailed discussion of the variance 
drivers by line item.

Operating Revenues. The variance was driven primarily by:

• a $603 million increase in retail pricing primarily due to the Duke 

Energy Carolinas and Duke Energy Progress North Carolina and South 
Carolina rate cases and Duke Energy Florida’s base rate adjustments 
related to Citrus County CC being placed in service.

Partially offset by:

• a $45 million decrease in weather-normal retail sales volumes.

Operating Expenses. The variance was driven primarily by:

• a $428 million increase in depreciation and amortization expense 

primarily due to additional plant in service and new depreciation rates 
associated with the Duke Energy Carolinas and Duke Energy Progress 
North Carolina and South Carolina rate cases and Duke Energy Florida’s 
Citrus County CC being placed in service; and

• a $41 million increase in property and other taxes primarily due to 
higher property taxes for additional plant in service at Duke Energy 
Florida and current year property tax reassessments at Duke Energy 
Progress and Duke Energy Ohio.

Partially offset by:

• a $317 million decrease in impairment charges primarily due to the 
impacts associated with the Duke Energy Carolinas and Duke Energy 

Progress North Carolina rate cases as well as impairment impacts 
related to Duke Energy Florida’s Citrus County CC; and

• a $134 million decrease in operation, maintenance and other expense 

primarily due to lower payroll and benefit costs resulting from prior year 
workforce reductions and lower storm costs at Duke Energy Progress 
and Duke Energy Carolinas in the current year.

Other Income and Expenses, net. The variance was driven primarily 
by AFUDC equity return ending on the Citrus County CC in the fourth quarter of 
2018 at Duke Energy Florida.

Interest Expense. The variance was driven primarily by higher debt 
outstanding in the current year and AFUDC debt return ending in the fourth 
quarter of 2018 on the Citrus County CC at Duke Energy Florida.

Income Tax Expense. The decrease in tax expense was primarily due 

to an increase in the amortization of excess deferred taxes, mostly offset by an 
increase in pretax income. The ETRs for the years ended December 31, 2019, 
and 2018, were 18.2% and 20.7%, respectively. The decrease in the ETR was 
primarily due to an increase in the amortization of excess deferred taxes.

Matters Impacting Future Electric Utilities and Infrastructure Results

On December 31, 2019, Duke Energy Carolinas and Duke Energy Progress 

entered into a settlement agreement with NCDEQ and certain community 
groups under which Duke Energy Carolinas and Duke Energy Progress agreed to 
excavate seven of the nine remaining coal ash basins in North Carolina with ash 
moved to on-site lined landfills. At the two remaining basins, uncapped basin 
ash will be excavated and moved to lined landfills. An order from regulatory 
authorities disallowing recovery of costs related to closure of these ash basins 
could have an adverse impact on Electric Utilities and Infrastructure’s results 
of operations, financial position and cash flows. See Notes 4 and 5 to the 
Consolidated Financial Statements, “Regulatory Matters” and “Commitments 
and Contingencies,” respectively, for additional information.

33

PART IIOn May 21, 2019, Duke Energy Carolinas and Duke Energy Progress 
received orders from the PSCSC granting the companies’ requests for retail 
rate increases but denying recovery of certain coal ash costs. Duke Energy 
Carolinas and Duke Energy Progress filed notices of appeals with the South 
Carolina Supreme Court on November 15, 2019. Appellant briefs are due on 
March 2, 2020, and Appellee response briefs are due on May 15, 2020. Electric 
Utilities and Infrastructure’s results of operations, financial position and cash 
flows could be adversely impacted if coal ash costs are not ultimately approved 
for recovery. See Note 4 to the Consolidated Financial Statements, “Regulatory 
Matters,” for additional information.

On June 22, 2018, Duke Energy Carolinas received an order from the 

NCUC, which denied the Grid Rider Stipulation and deferral treatment of grid 
improvement costs. Duke Energy Carolinas and Duke Energy Progress have 
petitioned for deferral of future grid improvement costs in their 2019 rate cases. 
Electric Utilities and Infrastructure’s results of operations, financial position 
and cash flows could be adversely impacted if grid improvement costs are not 
ultimately approved for recovery and/or deferral treatment.

During the last half of 2018, Duke Energy Carolinas, Duke Energy Progress 

and Duke Energy Florida’s service territories were impacted by several named 
storms. Hurricane Florence, Hurricane Michael and Winter Storm Diego caused 
flooding, extensive damage and widespread power outages to the service 
territories of Duke Energy Carolinas and Duke Energy Progress. Duke Energy 
Florida’s service territory was also impacted by Hurricane Michael, a Category 
5 hurricane and the most powerful storm to hit the Florida Panhandle in 
recorded history. In September 2019, Hurricane Dorian impacted Duke Energy 
Progress and Duke Energy Florida’s service territories. A significant portion of 
the incremental operation and maintenance expenses related to these storms 

has been deferred. An order from regulatory authorities disallowing the deferral 
and future recovery of storm restoration costs could have an adverse impact on 
Electric Utilities and Infrastructure’s results of operations, financial position and 
cash flows. See Note 4 to the Consolidated Financial Statements, “Regulatory 
Matters,” for additional information.

In 2019, Duke Energy Indiana filed a general rate case with the IURC, 

and Duke Energy Carolinas and Duke Energy Progress filed general rate cases 
with the NCUC. The outcome of these rate cases could materially impact 
Electric Utilities and Infrastructure’s results of operations, financial position and 
cash flows. See Note 4 to the Consolidated Financial Statements, “Regulatory 
Matters,” for additional information.

On April 17, 2015, the EPA published in the Federal Register a rule to 
regulate the disposal of CCR from electric utilities as solid waste. Duke Energy 
Indiana has interpreted the rule to identify the coal ash basin sites impacted 
and has assessed the amounts of coal ash subject to the rule and a method of 
compliance. Duke Energy Indiana’s interpretation of the requirements of the CCR 
rule is subject to potential legal challenges and further regulatory approvals, 
which could result in additional ash basin closure requirements, higher costs 
of compliance and greater AROs. Additionally, Duke Energy Indiana has retired 
facilities that are not subject to the CCR rule. Duke Energy Indiana may incur 
costs at these facilities to comply with environmental regulations or to mitigate 
risks associated with on-site storage of coal ash. An order from regulatory 
authorities disallowing recovery of costs related to closure of ash basins 
could have an adverse impact on Duke Energy Indiana’s results of operations, 
financial position and cash flows.

Gas Utilities and Infrastructure’s results were primarily impacted by 
higher equity earnings at ACP, the OTTI recorded on the Constitution investment 
and a 2019 adjustment related to the income tax recognition for equity method 
investments. The equity method investment adjustment was immaterial and 
relates to prior years. The following is a detailed discussion of the variance 
drivers by line item.

Operating Revenues. The variance was driven primarily by:

• a $70 million decrease due to lower natural gas costs passed through 

to customers; and

• a $13 million decrease due to rider revenues related to MGP and 

Accelerated Main Replacement Program.

Partially offset by:

• a $37 million increase due to North Carolina and Kentucky base rate 

case increases;

• a $19 million increase due to North Carolina and Tennessee IMR 

increases; and

• an $11 million increase due to NCUC approval related to tax reform 

accounting from fixed rate contracts.

PART IIOperating Expenses. The variance was driven primarily by:

Matters Impacting Future Gas Utilities and Infrastructure Results

• a $70 million decrease in the cost of natural gas due to lower natural 

gas prices.

Partially offset by:

• a $25 million increase in operation, maintenance and other expense 
primarily due to increased labor, benefits and information technology 
costs; and

• an $11 million increase in depreciation and amortization expense due to 

additional plant in service.

Other Income and Expenses, net. The increase was primarily due to 

higher equity earnings at ACP as a result of higher cumulative project spending 
and a higher OTTI recorded on the Constitution investment in the prior year.

Interest Expense. The variance was driven by higher debt outstanding in 
the current year and higher interest expense due to customers as a result of tax 
reform deferrals, partially offset by favorable AFUDC debt interest.

Income Tax Expense. The decrease in tax expense was primarily due 

to an adjustment related to the income tax recognition for equity method 
investments, partially offset by an increase in pretax income. The equity method 
investment adjustment was immaterial and relates to prior years. The ETRs 
for the years ended December 31, 2019, and 2018, were 4.8% and 22.2%, 
respectively. The decrease in the ETR was primarily due to an adjustment 
related to the income tax recognition for equity method investments that was 
recorded during the first quarter of 2019 and current year AFUDC equity. The 
equity method investment adjustment was immaterial and relates to prior years.

Gas Utilities and Infrastructure has a 47% ownership interest in ACP, 
which is building an approximately 600-mile interstate natural gas pipeline 
intended to transport diverse natural gas supplies into southeastern markets. 
Affected states (West Virginia, Virginia and North Carolina) have issued certain 
necessary permits; the project remains subject to other pending federal and 
state approvals, which will allow full construction activities to begin. In 2018, 
FERC issued a series of Notices to Proceed, which authorized the project to 
begin certain construction-related activities along the pipeline route. Given legal 
challenges and ongoing discussions with customers, ACP expects mechanical 
completion of the full project in late 2021 with in-service likely in the first half 
of 2022. The delays resulting from legal challenges have also impacted the 
cost for the project. Project cost is approximately $8 billion, excluding financing 
costs. This estimate is based on the current facts available around construction 
costs and timelines, and is subject to future changes as those facts develop. 
Abnormal weather, work delays (including delays due to judicial or regulatory 
action) and other conditions may result in cost or schedule modifications, a 
suspension of AFUDC for ACP and/or impairment charges potentially material to 
Duke Energy’s cash flows, financial position and results of operations. ACP and 
Duke Energy will continue to consider their options with respect to the foregoing 
given their existing contractual and legal obligations. See Notes 4 and 18 to the 
Consolidated Financial Statements, “Regulatory Matters” and “Variable Interest 
Entities,” respectively, for additional information.

On November 13, 2013, the PUCO issued an order authorizing recovery 

of MGP costs at certain sites in Ohio with a deadline to complete the MGP 
environmental investigation and remediation work prior to December 31, 2016. 
This deadline was subsequently extended to December 31, 2019. Duke Energy 
Ohio has filed a request for extension of the deadline. A hearing on that request 
has not been scheduled. Disallowance of costs incurred, failure to complete 
the work by the deadline or failure to obtain an extension from the PUCO could 
result in an adverse impact on Gas Utilities and Infrastructure’s results of 
operations, financial position and cash flows. See Note 4 to the Consolidated 
Financial Statements, “Regulatory Matters,” for additional information.

PART IIYear Ended December 31, 2019, as compared to 2018

Commercial Renewables’ results were favorable primarily due to new tax 

equity solar projects in the current year and a prior year goodwill impairment 
charge. The following is a detailed discussion of the variance drivers by line item.

Operating Revenues. The increase was primarily due to new solar 

projects placed in service and higher irradiance.

Operating Expenses. The decrease was primarily due to a goodwill 

impairment charge in the prior year, partially offset by increased depreciation 
due to new solar projects placed in service.

Other Income and Expenses, net. The decrease was primarily due to 

income from the FES settlement agreement in the prior year.

Income Tax Benefit. The decrease in the tax benefit was primarily driven 

by taxes associated with Duke Energy’s interest in tax equity solar projects 
recorded during 2019 and a reduction in PTCs generated.

Loss Attributable to Noncontrolling Interests. The variance was 

primarily due to an increase in solar projects with tax equity investors. HLBV 

accounting was utilized, resulting in allocation of losses to the noncontrolling 
interest partners. See Note 1 to the Consolidated Financial Statements, 
“Summary of Significant Accounting Policies” for more information.

Matters Impacting Future Commercial Renewables Results

Commercial Renewables continues to experience growth with tax equity 
projects; however, the future expiration of federal tax incentives could result in 
adverse impacts to future results of operations, financial position and cash flows.
During 2019, Duke Energy evaluated recoverability of its renewable 
merchant plants principally in the Electric Reliability Council of Texas West 
market, due to declining market pricing and declining long-term forecasted 
energy prices, primarily driven by lower forecasted natural gas prices. These 
assets were not impaired; however, a continued decline in energy market pricing 
would likely result in a future impairment. Impairment of these assets could 
result in adverse impacts to the future results of operations, financial position 
and cash flows of Commercial Renewables. See Note 11 to the Consolidated 
Financial Statements, “Property, Plant and Equipment,” for additional 
information.

The variance was driven by the prior year severance charges related to a 
corporate initiative, prior year loss on sale of the retired Beckjord station, and 
the absence in the current year of costs related to the Piedmont acquisition, 
offset by obligations to the Duke Energy Foundation in 2019. The following is a 
detailed discussion of the variance drivers by line item.

Operating Expenses. The variance was primarily due to prior year 
severance charges related to a corporate initiative as well as costs associated 
with the Piedmont acquisition, partially offset by obligations to the Duke Energy 
Foundation in 2019.

Losses on Sales of Other Assets and Other, net. The variance was 
driven by the prior year loss on sale of the retired Beckjord station, including 
the transfer of coal ash basins and other real property and indemnification 
from all potential future claims related to the property, whether arising under 
environmental laws or otherwise.

Other Income and Expenses, net. The variance was primarily due to 
higher returns on investments that fund certain employee benefit obligations 
and Bison investment income.

Interest Expense. The variance was primarily due to higher outstanding 

debt in the current year and higher short-term interest rates.

Income Tax Benefit. The decrease in the tax benefit was primarily driven 

by a decrease in pretax losses.

Preferred Dividends. The variance was driven by the declarations of 

preferred stock dividend on preferred stock issued in 2019.

Partially offset by:

Operating Revenues. The variance was driven primarily by:

• a $178 million increase in retail pricing due to the impacts of the prior year 
North Carolina rate case and the current year South Carolina rate case.

Partially offset by:

• a $41 million decrease in rider revenues primarily due to excess 

deferred taxes, partially offset by EE programs and a decrement rider 
relating to nuclear decommissioning that ended in the prior year;

• a $14 million decrease in weather-normal retail sales volumes; and

• a $7 million decrease in retail sales, net of fuel revenues, due to 

unfavorable weather in the current year.

Operating Expenses. The variance was driven primarily by:

• a $262 million decrease in operation, maintenance and other expense 
primarily due to decreased labor and storm restoration costs; and

• a $175 million decrease in impairment charges primarily due to 

impacts of the prior year North Carolina rate order, the repeal of the 
South Carolina Base Load Review Act and charges related to coal ash 
costs in South Carolina.

37

• a $187 million increase in depreciation and amortization expense 
primarily due to additional plant in service, new depreciation rates 
associated with the prior year North Carolina rate case and the current 
year South Carolina rate case and higher amortization of deferred coal 
ash costs associated with the prior year North Carolina rate case. 

Interest Expense. The variance was primarily due to higher debt 

outstanding in the current year.

Matters Impacting Future Results

On December 31, 2019, Duke Energy Carolinas entered into a settlement 

agreement with NCDEQ and certain community groups under which Duke Energy 
Carolinas agreed to excavate five of the six remaining coal ash basins in North 
Carolina with ash moved to on-site lined landfills. At the one remaining basin, 
uncapped basin ash will be excavated and moved to lined landfills. An order 
from regulatory authorities disallowing recovery of costs related to closure of 
these ash basins could have an adverse impact on Duke Energy Carolinas’ 
results of operations, financial position and cash flows. See Notes 4 and 5 to the 
Consolidated Financial Statements, “Regulatory Matters” and “Commitments 
and Contingencies,” respectively, for additional information.

PART IIDuke Energy Carolinas filed a general rate case with the NCUC on 
September 30, 2019. The outcome of this rate case could materially impact 
Duke Energy Carolina’s results of operations, financial position and cash flows. 
See Note 4 to the Consolidated Financial Statements, “Regulatory Matters,” for 
additional information.

On May 21, 2019, the PSCSC issued an order granting Duke Energy 
Carolinas request for a retail rate increase but denying recovery of certain 
coal ash costs. Duke Energy Carolinas filed a notice of appeal with the South 
Carolina Supreme Court on November 15, 2019. Appellant briefs are due on 
March 2, 2020, and Appellee response briefs are due on May 15, 2020. Duke 
Energy Carolinas’ results of operations, financial position and cash flows could 
be adversely impacted if coal ash costs are not ultimately approved for recovery. 
See Note 4 to the Consolidated Financial Statements, “Regulatory Matters,” for 
additional information.

On June 22, 2018, Duke Energy Carolinas received an order from the NCUC, 
which denied the Grid Rider Stipulation and deferral treatment of grid improvement 

costs. Duke Energy Carolinas has petitioned for deferral of future grid improvement 
costs in its 2019 rate case. Duke Energy Carolinas’ results of operations, financial 
position and cash flows could be adversely impacted if grid improvement costs are 
not ultimately approved for recovery and/or deferral treatment.

During the last half of 2018, Duke Energy Carolinas’ service territory was 
impacted by several named storms. Hurricane Florence, Hurricane Michael and 
Winter Storm Diego caused flooding, extensive damage and widespread power 
outages in the service territory. A significant portion of the incremental operation 
and maintenance expenses related to these storms has been deferred. An order 
from regulatory authorities disallowing the deferral and future recovery of storm 
restoration costs could have an adverse impact on Duke Energy Carolinas’ results 
of operations, financial position and cash flows. See Note 4 to the Consolidated 
Financial Statements, “Regulatory Matters,” for additional information.

Operating Revenues. The variance was driven primarily by:

• a $21 million increase in other revenues primarily due to increased 
transmission revenues and nonregulated products and services 
revenues at Duke Energy Florida.

• a $366 million increase in retail pricing primarily due to the impacts of 
the prior year North Carolina rate case and current year South Carolina 
rate case at Duke Energy Progress, Duke Energy Florida’s base rate 
adjustments related to Citrus County CC being placed in service and 
annual increases from the 2017 Settlement Agreement;

• a $70 million increase in wholesale power revenues, net of fuel, 

primarily due to coal ash cost recovery in the current year at Duke 
Energy Progress and increased demand at Duke Energy Florida;

• a $42 million increase in fuel revenues primarily related to increased 
fuel cost recovery due to extreme weather in the prior year at Duke 
Energy Progress, partially offset by a decrease in fuel and capacity 
rates billed to retail customers at Duke Energy Florida;

• a $22 million increase in retail sales, net of fuel revenues, due to 
favorable weather in the current year at Duke Energy Florida; and

38

Partially offset by:

• a $47 million decrease in retail rider revenues primarily related to 

decreased revenue requirements in the current year; and

• a $14 million decrease in weather-normal retail sales volumes at Duke 

Energy Florida.

Operating Expenses. The variance was driven primarily by:

• a $226 million increase in depreciation and amortization expense 
primarily due to higher amortization of deferred coal ash costs, 
new depreciation rates associated with the prior year Duke Energy 
Progress North Carolina rate case and Duke Energy Florida’s base rate 
adjustments related to Citrus County CC being placed in service;

PART II• a $48 million increase in fuel used in electric generation and purchased 
power primarily due to an increase in the North Carolina Renewable 
Energy and Energy Efficiency Portfolio Standard requirement from the 
prior year at Duke Energy Progress, partially offset by lower purchased 
power and lower fuel costs, net of deferrals, at Duke Energy Florida; and

• a $32 million increase in property and other taxes primarily due to 

current year property tax reassessments and a favorable sales and use 
tax credit in the prior year at Duke Energy Progress and higher property 
taxes for additional plant in service at Duke Energy Florida.

Partially offset by:

• a $118 million decrease in operation, maintenance and other expense 
primarily due to lower storm costs, reduced outage costs, and lower 
employee benefit costs, partially offset by increased vegetation 
management costs at Duke Energy Florida; and

• a $111 million decrease in impairment charges primarily due to prior 
year impacts associated with the North Carolina rate case at Duke 
Energy Progress as well as the impairment of Duke Energy Florida’s 
Citrus County CC.

Other Income and Expenses, net. The variance was driven primarily 
by AFUDC equity return ending on the Citrus County CC in the fourth quarter of 
2018 at Duke Energy Florida, partially offset by life insurance proceeds at Duke 
Energy Progress.

Interest Expense. The variance was driven primarily by AFUDC debt 
return ending in the fourth quarter of 2018 on the Citrus County CC at Duke 
Energy Florida.

Income Tax Expense. The increase in tax expense was primarily due to 
an increase in pretax income, partially offset by an increase in the amortization 
of excess deferred taxes and a Tax Act adjustment in the prior year related to 
excess deferred taxes.

increase in the North Carolina Renewable Energy and Energy Efficiency 
Portfolio Standard requirement from prior year, partially offset by lower 
demand and changes in generation mix; and

• a $21 million increase in property and other taxes primarily due to 

current year property tax reassessments and a favorable sales and use 
tax credit in the prior year.

Partially offset by:

• a $132 million decrease in operation, maintenance and other expense 

primarily due to lower storm costs in current year, reduced outage costs 
and lower employee benefit costs; and

• a $21 million decrease in impairment charges primarily due to prior 

year impacts associated with the North Carolina rate case.

Other Income and Expenses, net. The variance was driven primarily by 

life insurance proceeds.

Operating Revenues. The variance was driven primarily by:

• a $256 million increase in retail pricing due to base rate adjustments 
related to Citrus County CC being placed in service, annual increases 
from the 2017 Settlement Agreement and the Solar Base Rate 
Adjustment;

• a $22 million increase in retail sales, net of fuel revenues, due to 

favorable weather in the current year;

• a $21 million increase in other revenues primarily due to increased 
transmission revenues and nonregulated products and services 
revenues; and

• a $16 million increase in wholesale power revenues, net of fuel, 

primarily due to increased demand.

Partially offset by:

• a $59 million decrease in fuel and capacity revenues primarily due to a 

decrease in fuel and capacity rates billed to retail customers; 

• a $33 million decrease in retail rider revenues primarily related to 

decreased revenue requirements in the current year; and

• a $14 million decrease in weather-normal retail sales volumes.

Operating Expenses. The variance was driven primarily by:

• a $90 million decrease in impairment charges primarily due to a prior 

year impairment at Citrus County CC and a reduction of the impairment 
in the current year; and

• a $73 million decrease in fuel used in electric generation and 

purchased power primarily due to lower purchased power and lower 
fuel costs, net of deferrals.

Partially offset by:

• a $74 million increase in depreciation and amortization expense 

primarily due to base rate adjustments related to Citrus County CC 
being placed in service, other additional plant in service and increases 
resulting from the 2018 Crystal River Unit 3 nuclear decommissioning 
cost study;

• an $18 million increase in property and other taxes primarily due to 

higher property taxes from additional plant in service; and

• a $9 million increase in operation, maintenance and other expense 
primarily due to increased vegetation management costs and 
deregulation initiative costs, partially offset by lower severance 
charges.

Other Income and Expenses, net. The variance was driven primarily by 
AFUDC equity return ending on the Citrus County CC in the fourth quarter of 2018.

41

PART IIInterest Expense. The variance was driven primarily by AFUDC debt 

return ending on the Citrus County CC in the fourth quarter of 2018 and higher 
debt outstanding in the current year.

Income Tax Expense. The increase in tax expense was primarily due to 

an increase in pretax income in the current year.

Matters Impacting Future Results

On October 10, 2018, Hurricane Michael made landfall on Florida’s 
Panhandle as a Category 5 hurricane, the most powerful storm to hit the Florida 
Panhandle in recorded history. The storm caused significant damage within the 
service territory of Duke Energy Florida, particularly from Panama City Beach to 

Mexico Beach. In September 2019, Duke Energy Florida’s service territory was 
threatened by Hurricane Dorian with landfall as a possible Category 5 hurricane 
and therefore Duke Energy Florida incurred costs to secure necessary resources 
to be prepared for that potential impact. A significant portion of the incremental 
operation and maintenance expenses related to these storms has been 
deferred. An order from regulatory authorities disallowing the future recovery 
of storm restoration costs could have an adverse impact on Duke Energy 
Florida’s financial position, results of operations and cash flows. See Note 4 
to the Consolidated Financial Statements, “Regulatory Matters,” for additional 
information.

PART IIYear Ended December 31, 2019, as compared to 2018

Operating Revenues. The variance was driven primarily by:

• an $18 million increase in property and other taxes primarily due to 

additional plant in service, partially offset by a negotiated reassessment 
of property values and property tax true ups for prior periods.

• a $45 million decrease in fuel related revenues primarily due to a 

decrease in price;

Partially offset by:

• a $31 million decrease in rider revenues primarily due to the cessation 
of the Smart Grid Rider in 2018 and the Tax Cut and Jobs Act Rider 
beginning in 2019, partially offset by new riders implemented in 
conjunction with rate cases including the Price Stabilization Rider, 
Electric Service Reliability Rider and the Environmental Surcharge 
Mechanism;

• a $15 million decrease in FTR rider revenues; and 

• a $12 million decrease in electric and natural gas retail sales, net of 

fuel revenues, due to unfavorable weather in the current year.

Partially offset by:

• a $71 million increase in retail pricing primarily due to rate case 

impacts; and 

• an $18 million increase in PJM point-to-point transmission revenues 

due to an increase in the Network Integration Transmission Service rate 
primarily due to additional plant in service.

Operating Expenses. The variance was driven primarily by:

• a $40 million increase in operations, maintenance and other expense 
primarily due to the FERC approved settlement refund of certain 
transmission costs previously billed by PJM recorded in 2018 and 
increased PJM transmission expansion fees; and

• a $24 million decrease in fuel used in electric generation and purchased 
power expense due to the prior year outage at East Bend Station and 
the deferral of OVEC related purchased power costs; and

• an $18 million decrease in the cost of natural gas primarily due to lower 
costs passed through to customers, as a result of a lower natural gas 
prices.

Losses on Sales of Other Assets and Other, net. The increase was 

driven by the loss on the prior year sale of Beckjord.

Interest Expense. The variance was primarily due to higher debt 

outstanding in the current year.

Matters Impacting Future Results

On November 13, 2013, the PUCO issued an order authorizing recovery 

of MGP costs at certain sites in Ohio with a deadline to complete the MGP 
environmental investigation and remediation work prior to December 31, 2016. 
This deadline was subsequently extended to December 31, 2019. Duke Energy 
Ohio has filed a request for extension of the deadline. A hearing on that request 
has not been scheduled. Disallowance of costs incurred, failure to complete 
the work by the deadline or failure to obtain an extension from the PUCO 
could result in an adverse impact on Duke Energy Ohio’s results of operations, 
financial position and cash flows. See Note 4 to the Consolidated Financial 
Statements, “Regulatory Matters,” for additional information.

Operating Revenues. The variance was driven primarily by:

• a $21 million decrease in wholesale power revenues primarily due to 

the expiration of a contract with a wholesale customer; 

• a $16 million decrease in other transmission FTR revenues due to lower 

congestion; and

• a $14 million decrease in weather-normal retail sales volume. 

Operating Expenses. The variance was driven primarily by:

• a $65 million decrease in fuel used in electric generation and purchased 

power expense primarily due to lower coal and natural gas costs, 
partially offset by higher purchase power fuel clause, higher amortization 
of deferred fuel costs and higher deferred MISO charges; and

• a $30 million decrease in impairments primarily due to the prior year 

Edwardsport IGCC settlement agreement.

On April 17, 2015, the EPA published in the Federal Register a rule to 
regulate the disposal of CCR from electric utilities as solid waste. Duke Energy 
Indiana has interpreted the rule to identify the coal ash basin sites impacted 
and has assessed the amounts of coal ash subject to the rule and a method of 
compliance. Duke Energy Indiana’s interpretation of the requirements of the CCR 
rule is subject to potential legal challenges and further regulatory approvals, 
which could result in additional ash basin closure requirements, higher costs 
of compliance and greater AROs. Additionally, Duke Energy Indiana has retired 
facilities that are not subject to the CCR rule. Duke Energy Indiana may incur 
costs at these facilities to comply with environmental regulations or to mitigate 
risks associated with on-site storage of coal ash. An order from regulatory 
authorities disallowing recovery of costs related to closure of ash basins 
could have an adverse impact on Duke Energy Indiana’s results of operations, 
financial position and cash flows.

Duke Energy Indiana filed a general rate case with the IURC on July 2, 
2019, its first general rate case in Indiana in 16 years. The outcome of this 
rate case could materially impact Duke Energy Indiana’s results of operations, 
financial position and cash flows. See Note 4 to the Consolidated Financial 
Statements, “Regulatory Matters,” for additional information.

Piedmont’s throughput was 511,243,774 Dth and 557,145,128 Dth for 

the years ended December 31, 2019, and 2018, respectively. Due to the margin 
decoupling mechanism in North Carolina, WNA mechanisms in South Carolina 
and Tennessee and fixed price contracts with most power generation customers, 
changes in throughput deliveries do not have a material impact on Piedmont’s 
revenues or earnings. The margin decoupling mechanism adjusts for variations 
in residential and commercial use per customer, including those due to weather 
and conservation. The WNA mechanisms mostly offset the impact of weather on 
bills rendered, but do not ensure full recovery of approved margin during periods 
when winter weather is significantly warmer or colder than normal.

challenges, earnings assumptions on pension and other benefit fund 
investments and anticipated recovery of costs, especially through regulated 
operations.

Management discusses these policies, estimates and assumptions with 

senior members of management on a regular basis and provides periodic 
updates on management decisions to the Audit Committee. Management 
believes the areas described below require significant judgment in the 
application of accounting policy or in making estimates and assumptions that 
are inherently uncertain and that may change in subsequent periods.

For further information, see Note 1 to the Consolidated Financial 

Statements, “Summary of Significant Accounting Policies.”

Operating Revenues. The variance was driven primarily by:

• a $24 million increase due to North Carolina base rate case increases;

• a $19 million increase due to North Carolina and Tennessee IMR 

increases; and

• an $11 million increase due to NCUC approval related to tax reform 

accounting from fixed rate contracts.

Partially offset by:

Regulated Operations Accounting

Substantially all of Duke Energy’s regulated operations meet the criteria 
for application of regulated operations accounting treatment. As a result, Duke 
Energy is required to record assets and liabilities that would not be recorded 
for nonregulated entities. Regulatory assets generally represent incurred costs 
that have been deferred because such costs are probable of future recovery in 
customer rates. Regulatory liabilities are recorded when it is probable that a 
regulator will require Duke Energy to make refunds to customers or reduce rates 
to customers for previous collections or deferred revenue for costs that have yet 
to be incurred.

Management continually assesses whether recorded regulatory assets are 

probable of future recovery by considering factors such as:

• applicable regulatory environment changes;

• historical regulatory treatment for similar costs in Duke Energy’s 

• a $52 million decrease in cost of natural gas due to lower natural gas 

jurisdictions;

• a $29 million decrease in operation, maintenance and other expense 
due to lower information technology outside services and labor costs.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Preparation of financial statements requires the application of accounting 

policies, judgments, assumptions and estimates that can significantly affect 
the reported results of operations, cash flows or the amounts of assets and 
liabilities recognized in the financial statements. Judgments made include 
the likelihood of success of particular projects, possible legal and regulatory 

45

If future recovery of costs ceases to be probable, asset write-offs would 

be recognized in operating income. Additionally, regulatory agencies can provide 
flexibility in the manner and timing of the depreciation of property, plant and 
equipment, recognition of asset retirement costs and amortization of regulatory 
assets, or may disallow recovery of all or a portion of certain assets.

As required by regulated operations accounting rules, significant judgment 
can be required to determine if an otherwise recognizable incurred cost qualifies 
to be deferred for future recovery as a regulatory asset. Significant judgment can 
also be required to determine if revenues previously recognized are for entity 
specific costs that are no longer expected to be incurred or have not yet been 
incurred and are therefore a regulatory liability.

PART IIGoodwill Impairment Assessments

Duke Energy performed its annual goodwill impairment tests for all 
reporting units as of August 31, 2019. Additionally, Duke Energy monitors all 
relevant events and circumstances during the year to determine if an interim 
impairment test is required. Such events and circumstances include an 
adverse regulatory outcome, declining financial performance and deterioration 
of industry or market conditions. As of August 31, 2019, all of the reporting 
units’ estimated fair value of equity substantially exceeded the carrying value of 
equity. The fair values of the reporting units were calculated using a weighted 
combination of the income approach, which estimates fair value based on 
discounted cash flows, and the market approach, which estimates fair value 
based on market comparables within the utility and energy industries.

Estimated future cash flows under the income approach are based on 
Duke Energy’s internal business plan. Significant assumptions used are growth 
rates, future rates of return expected to result from ongoing rate regulation and 
discount rates. Management determines the appropriate discount rate for each 
of its reporting units based on the WACC for each individual reporting unit. The 
WACC takes into account both the after-tax cost of debt and cost of equity. A 
major component of the cost of equity is the current risk-free rate on 20-year 
U.S. Treasury bonds. In the 2019 impairment tests, Duke Energy considered 
implied WACCs for certain peer companies in determining the appropriate WACC 
rates to use in its analysis. As each reporting unit has a different risk profile 
based on the nature of its operations, including factors such as regulation, the 
WACC for each reporting unit may differ. Accordingly, the WACCs were adjusted, 
as appropriate, to account for company specific risk premiums. The discount 
rates used for calculating the fair values as of August 31, 2019, for each of 
Duke Energy’s reporting units ranged from 5.2% to 5.9%. The underlying 
assumptions and estimates are made as of a point in time. Subsequent 
changes, particularly changes in the discount rates, authorized regulated rates 
of return or growth rates inherent in management’s estimates of future cash 
flows, could result in future impairment charges.

One of the most significant assumptions utilized in determining the fair 

value of reporting units under the market approach is implied market multiples 
for certain peer companies. Management selects comparable peers based 
on each peer’s primary business mix, operations, and market capitalization 
compared to the applicable reporting unit and calculates implied market 
multiples based on available projected earnings guidance and peer company 
market values as of August 31.

Duke Energy primarily operates in environments that are rate-regulated. 

In such environments, revenue requirements are adjusted periodically by 
regulators based on factors including levels of costs, sales volumes and costs 
of capital. Accordingly, Duke Energy’s regulated utilities operate to some degree 
with a buffer from the direct effects, positive or negative, of significant swings in 
market or economic conditions. However, significant changes in discount rates 
over a prolonged period may have a material impact on the fair value of equity.
For further information, see Note 12 to the Consolidated Financial 

Statements, “Goodwill and Intangible Assets.”

Asset Retirement Obligations

AROs are recognized for legal obligations associated with the retirement of 
property, plant and equipment at the present value of the projected liability in the 
period in which it is incurred, if a reasonable estimate of fair value can be made.

The present value of the initial obligation and subsequent updates are 
based on discounted cash flows, which include estimates regarding timing of 
future cash flows, selection of discount rates and cost escalation rates, among 
other factors. These estimates are subject to change.

Obligations for nuclear decommissioning are based on site-specific cost 

studies. Duke Energy Carolinas and Duke Energy Progress assume prompt 
dismantlement of the nuclear facilities after operations are ceased. During 
2019, Duke Energy Florida, entered into an agreement for the accelerated 
decommissioning of the Crystal River Unit 3 nuclear power station. Closing 
of this agreement is contingent upon approval of the NRC and FPSC. The 

retirement obligations for the decommissioning of Crystal River Unit 3 nuclear 
power station are measured using probability weightings of an obligation based 
on accelerated decommissioning from 2020 continuing through 2027 and an 
obligation based on the unit in SAFSTOR, with decommissioning beginning in 
2067 and ending in 2074. Duke Energy Carolinas, Duke Energy Progress and 
Duke Energy Florida also assume that spent fuel will be stored on-site until such 
time that it can be transferred to a yet to be built DOE facility.

Obligations for closure of ash basins are based upon discounted cash flows 

of estimated costs for site-specific plans. During 2019, Duke Energy reached 
a settlement agreement with the NCDEQ and SELC to excavate 7 and partially 
excavate 2 of the remaining ash basins in Duke Energy Carolinas and Duke Energy 
Progress service territories. In 2019, Duke Energy Carolinas and Duke Energy 
Progress remeasured their obligations to reflect the results of the settlement.

For further information, see Notes 4, 5 and 10 to the Consolidated 
Financial Statements, “Regulatory Matters,” “Commitments and Contingencies” 
and “Asset Retirement Obligations.”

Long-Lived Asset Impairment Assessments, Excluding Regulated 

Operations

Duke Energy evaluates property, plant and equipment for impairment 
when events or changes in circumstances (such as a significant change in 
cash flow projections or the determination that it is more likely than not that an 
asset or asset group will be sold) indicate the carrying value of such assets may 
not be recoverable. The determination of whether an impairment has occurred 
is based on an estimate of undiscounted future cash flows attributable to the 
assets, as compared with their carrying value.

Performing an impairment evaluation involves a significant degree of 

estimation and judgment in areas such as identifying circumstances that 
indicate an impairment may exist, identifying and grouping affected assets and 
developing the undiscounted future cash flows. If an impairment has occurred, 
the amount of the impairment recognized is determined by estimating the fair 
value and recording a loss if the carrying value is greater than the fair value. 
Additionally, determining fair value requires probability weighting future cash 
flows to reflect expectations about possible variations in their amounts or timing 
and the selection of an appropriate discount rate. Although cash flow estimates 
are based on relevant information available at the time the estimates are made, 
estimates of future cash flows are, by nature, highly uncertain and may vary 
significantly from actual results.

When determining whether an asset or asset group has been impaired, 
management groups assets at the lowest level that has discrete cash flows.

During 2019, Duke Energy sold a minority interest in a portion of certain 

Commercial Renewable assets. Following the sale, Duke Energy evaluated 
recoverability of the assets included in the sale as the fair value of consideration 
received for the portfolio was less than the carrying value of the assets. It 
was determined the assets were all recoverable. Additionally, Duke Energy 
evaluated recoverability of certain renewable merchant plants during 2019 due 
to declining market pricing and declining long-term forecasted energy prices. 
It was determined the assets were all recoverable as the carrying value of the 
assets approximated the aggregate estimated future cash flows.

For further information, see Notes 3 and 11 to the Consolidated Financial 

Statements, “Business Segments” and “Property, Plant and Equipment.”

Equity Method Investments

Equity method investments are assessed for impairment when conditions 
exist that indicate that the fair value of the investment is less than book value. 
If the decline in value is considered to be other-than-temporary, an impairment 
charge is recorded and the investment is written down to its estimated fair 
value, which establishes a new cost basis in the investment.

Events or changes in circumstances are monitored that may indicate, 

in management’s judgment, the carrying value of such investments may have 
experienced an other-than-temporary decline in value. The fair value of equity 
method investments is generally estimated using an income approach where 

46

PART IIin assumptions can result in different expense and reported asset or liability 
amounts and future actual experience can differ from the assumptions. Duke 
Energy believes the most critical assumptions for pension and other post-
retirement benefits are:

• the expected long-term rate of return on plan assets;

• the assumed discount rate applied to future projected benefit 

payments; and 

• the heath care cost trend rate.

Duke Energy elects to amortize net actuarial gain or loss amounts that are 

in excess of 10% of the greater of the market-related value of plan assets or 
the plan’s projected benefit obligation, into net pension or other post-retirement 
benefit expense over the average remaining service period of active participants 
expected to benefit under the plan. If all or almost all of a plan’s participants 
are inactive, the average remaining life expectancy of the inactive participants 
is used instead of average remaining service period. Prior service cost or credit, 
which represents an increase or decrease in a plan’s pension benefit obligation 
resulting from plan amendment, is amortized on a straight-line basis over the 
average expected remaining service period of active participants expected to 
benefit under the plan. If all or almost all of a plan’s participants are inactive, 
the average remaining life expectancy of the inactive participants is used 
instead of average remaining service period.

As of December 31, 2019, Duke Energy assumes pension and other 
post-retirement plan assets will generate a long-term rate of return of 6.85%. 
The expected long-term rate of return was developed using a weighted 
average calculation of expected returns based primarily on future expected 
returns across asset classes considering the use of active asset managers, 
where applicable. The asset allocation targets were set after considering the 
investment objective and the risk profile. Equity securities are held for their 
higher expected returns. Debt securities are primarily held to hedge the qualified 
pension liability. Real assets, return-seeking fixed income, hedge funds and 
other global securities are held for diversification. Investments within asset 
classes are diversified to achieve broad market participation and reduce the 
impact of individual managers on investments.

Duke Energy discounted its future U.S. pension and other post-retirement 
obligations using a rate of 3.3% as of December 31, 2019. Discount rates used 
to measure benefit plan obligations for financial reporting purposes reflect 
rates at which pension benefits could be effectively settled. As of December 
31, 2019, Duke Energy determined its discount rate for U.S. pension and 
other post-retirement obligations using a bond selection-settlement portfolio 
approach. This approach develops a discount rate by selecting a portfolio of 
high quality corporate bonds that generate sufficient cash flow to provide for 
projected benefit payments of the plan. The selected bond portfolio is derived 
from a universe of non-callable corporate bonds rated Aa quality or higher. After 
the bond portfolio is selected, a single interest rate is determined that equates 
the present value of the plan’s projected benefit payments discounted at this 
rate with the market value of the bonds selected.

Future changes in plan asset returns, assumed discount rates and 
various other factors related to the participants in Duke Energy’s pension 
and post-retirement plans will impact future pension expense and liabilities. 
Duke Energy cannot predict with certainty what these factors will be in the future. 
The following table presents the approximate effect on Duke Energy’s 2019 pretax 
pension expense, pretax other post-retirement expense, pension obligation and 
other post-retirement benefit obligation if a 0.25% change in rates were to occur.

significant judgments and assumptions include expected future cash flows, the 
appropriate discount rate, and probability weighted-scenarios, if applicable. 
In certain instances, a market approach may also be used to estimate the fair 
value of the equity method investment.

Events or changes in circumstances that may be indicative of an other-

than-temporary decline in value will vary by investment, but may include:

• Significant delays in or failure to complete significant growth projects 

of investees;

• Adverse regulatory actions expected to substantially reduce the 

investee’s product demand or profitability;

• Expected financial performance significantly worse than anticipated 

when initially invested;

• Prolonged period the fair value is below carrying value;

• A significant or sustained decline in the market value of an investee;

• Lower than expected cash distributions from investees;

• Significant asset impairments or operating losses recognized by 

investees; and

• Loss of significant customers or suppliers with no immediate prospects 

for replacement.

ACP

As of December 31, 2019, the carrying value of the equity method 
investment in ACP is $1.2 billion, and Duke Energy’s maximum exposure to loss 
for its guarantee of the ACP revolving credit facility is $827 million. During 2018 
and 2019, ACP received several adverse court rulings as described in Note 4 to 
the Consolidated Financial Statements, “Regulatory Matters.” As a result, Duke 
Energy evaluated this investment for impairment and determined that fair value 
approximated carrying value and therefore no impairment was necessary.

Duke Energy estimated the fair value of its investment in ACP using an 
income approach that primarily considered probability-weighted scenarios of 
discounted future net cash flows based on the most recent estimate of total 
construction costs and revenues. These scenarios included assumptions of 
various court decisions and the impact those decisions may have on the timing 
and extent of investment, including scenarios assuming the full resolution 
of permitting issues in addition to a scenario where the project does not 
proceed. Certain scenarios within the analysis included growth expectations 
from additional compression or other expansion opportunities and reopeners 
for pricing. An after-tax discount rate of 5.9% was used in the analysis. The 
discount rate was derived using a market participant approach with an adjusted 
risk premium for the underlying investment. Higher probabilities were generally 
assigned to those scenarios where court approvals were received and the project 
moves forward reflecting interim rates at prices subject to the reopeners. A low 
probability was assigned to the scenario where the project does not proceed.

Judgments and assumptions are inherent in our estimates of future cash 
flows, discount rates, growth assumptions, and the likelihood of various scenarios. 
It is reasonably possible that future unfavorable developments, such as a reduced 
likelihood of success with court approvals, increased estimates of construction 
costs, material increases in the discount rate, important feedback on customer 
price increases or further significant delays, could result in a future impairment.
For further information on ACP, see Notes 4 and 13 to the Consolidated 
Financial Statements, “Regulatory Matters” and “Investments in Unconsolidated 
Affiliates”.

Duke Energy’s other post-retirement plan uses a health care cost trend rate covering both pre- and post-age 65 retired plan participants, which is comprised 

of a medical care cost trend rate, which reflects the near- and long-term expectation of increases in medical costs, and a prescription drug cost trend rate, which 
reflects the near- and long-term expectation of increases in prescription drug costs. As of December 31, 2019, the health care cost trend rate was 6.0%, trending 
down to 4.75% by 2026. These plans are closed to new employees.

For further information, see Note 23 to the Consolidated Financial Statements, “Employee Benefit Plans.”

LIQUIDITY AND CAPITAL RESOURCES

Sources and Uses of Cash

Duke Energy relies primarily upon cash flows from operations, debt and 

equity issuances and its existing cash and cash equivalents to fund its liquidity 
and capital requirements. Duke Energy’s capital requirements arise primarily 
from capital and investment expenditures, repaying long-term debt and paying 
dividends to shareholders.

Among other provisions, the Tax Act lowered the corporate federal income 

tax rate from 35% to 21% and eliminated bonus depreciation for regulated 
utilities. For Duke Energy’s regulated operations, the reduction in federal 
income taxes will result in lower regulated customer rates. However, due to 
its existing NOL position and other tax credits, Duke Energy does not expect to 
be a significant federal cash tax payer through at least 2027. As a result, any 
reduction in customer rates could cause a material reduction in consolidated 
cash flows from operations in the short term. Over time, the reduction in 
deferred tax liabilities resulting from the Tax Act will increase Duke Energy’s 
regulated rate base investments and customer rates. Impacts of Tax Act to Duke 
Energy’s cash flows and credit metrics are subject to the regulatory actions 
of its state commissions, of which a substantial amount remain uncertain 
through ongoing rate case activity, and the FERC. See Note 4 to the Consolidated 
Financial Statements, “Regulatory Matters,” for additional information.

The Subsidiary Registrants generally maintain minimal cash balances and 

use short-term borrowings to meet their working capital needs and other cash 
requirements. The Subsidiary Registrants, excluding Progress Energy, support 
their short-term borrowing needs through participation with Duke Energy and 
certain of its other subsidiaries in a money pool arrangement. The companies with 
short-term funds may provide short-term loans to affiliates participating under 
this arrangement. See Note 7 to the Consolidated Financial Statements, “Debt and 
Credit Facilities,” for additional discussion of the money pool arrangement.

Duke Energy and the Subsidiary Registrants, excluding Progress Energy, 

may also use short-term debt, including commercial paper and the money 
pool, as a bridge to long-term debt financings. The levels of borrowing may 
vary significantly over the course of the year due to the timing of long-term 
debt financings and the impact of fluctuations in cash flows from operations. 
From time to time, Duke Energy’s current liabilities exceed current assets 
resulting from the use of short-term debt as a funding source to meet scheduled 
maturities of long-term debt, as well as cash needs, which can fluctuate due to 
the seasonality of its businesses.

Equity Issuance

In order to strengthen its balance sheet and credit metrics and bolster 

cash flows, in November 2019, Duke Energy entered into forward sales 
agreements for $2.5 billion of common stock equity expected to be settled in late 

48

2020. Duke Energy plans to issue $500 million of common stock equity per year 
through at least 2022 through the DRIP and ATM programs. Additionally, Duke 
Energy will utilize other instruments as needed. See Note 20 to the Consolidated 
Financial Statements, “Stockholders’ Equity,” for further information regarding 
Duke Energy’s equity issuances in 2019.

Credit Facilities and Registration Statements

See Note 7 to the Consolidated Financial Statements, “Debt and Credit 
Facilities,” for further information regarding credit facilities and shelf registration 
statements available to Duke Energy and the Duke Energy Registrants.

CAPITAL EXPENDITURES

Duke Energy continues to focus on reducing risk and positioning its 
business for future success and will invest principally in its strongest business 
sectors. Duke Energy’s projected capital and investment expenditures, including 
AFUDC debt and capitalized interest, for the next three fiscal years are included 
in the table below.

PART IIDIVIDEND PAYMENTS

In 2019, Duke Energy paid quarterly cash dividends for the 93rd 
consecutive year and expects to continue its policy of paying regular cash 
dividends in the future. There is no assurance as to the amount of future 
dividends because they depend on future earnings, capital requirements, 
financial condition and are subject to the discretion of the Board of Directors.
Duke Energy targets a dividend payout ratio of between 65% and 75%, 
based upon adjusted diluted EPS, and expects this trend to continue through 
2024. In 2019 and 2018, Duke Energy increased the dividend by approximately 
2% and 4%, respectively, and the company remains committed to continued 
growth of the dividend.

Dividend and Other Funding Restrictions of Duke Energy Subsidiaries

As discussed in Note 4 to the Consolidated Financial Statements, 

“Regulatory Matters,” Duke Energy’s wholly owned public utility operating 
companies have restrictions on the amount of funds that can be transferred 
to Duke Energy through dividends, advances or loans as a result of conditions 
imposed by various regulators in conjunction with merger transactions. Duke 
Energy Progress and Duke Energy Florida also have restrictions imposed by 
their first mortgage bond indentures and Articles of Incorporation, which in 
certain circumstances, limit their ability to make cash dividends or distributions 
on common stock. Additionally, certain other Duke Energy subsidiaries have 
other restrictions, such as minimum working capital and tangible net worth 
requirements pursuant to debt and other agreements that limit the amount 
of funds that can be transferred to Duke Energy. At December 31, 2019, the 
amount of restricted net assets of wholly owned subsidiaries of Duke Energy 
that may not be distributed to Duke Energy in the form of a loan or dividend does 
not exceed a material amount of Duke Energy’s net assets. Duke Energy does 
not have any legal or other restrictions on paying common stock dividends to 
shareholders out of its consolidated equity accounts. Although these restrictions 
cap the amount of funding the various operating subsidiaries can provide 
to Duke Energy, management does not believe these restrictions will have a 
significant impact on Duke Energy’s ability to access cash to meet its payment 
of dividends on common stock and other future funding obligations.

CASH FLOWS FROM OPERATING ACTIVITIES

Cash flows from operations of Electric Utilities and Infrastructure and Gas 
Utilities and Infrastructure are primarily driven by sales of electricity and natural 
gas, respectively, and costs of operations. These cash flows from operations 
are relatively stable and comprise a substantial portion of Duke Energy’s 
operating cash flows. Weather conditions, working capital and commodity price 
fluctuations and unanticipated expenses including unplanned plant outages, 
storms, legal costs and related settlements can affect the timing and level of 
cash flows from operations.

Duke Energy believes it has sufficient liquidity resources through the 
commercial paper markets, and ultimately, the Master Credit Facility, to support 
these operations. Cash flows from operations are subject to a number of other 
factors, including, but not limited to, regulatory constraints, economic trends 
and market volatility (see Item 1A, “Risk Factors,” for additional information).
At December 31, 2019, Duke Energy had cash and cash equivalents and 

short-term investments of $311 million.

DEBT ISSUANCES

Depending on availability based on the issuing entity, the credit rating of 
the issuing entity, and market conditions, the Subsidiary Registrants prefer to 
issue first mortgage bonds and secured debt, followed by unsecured debt. This 
preference is the result of generally higher credit ratings for first mortgage bonds 
and secured debt, which typically result in lower interest costs. Duke Energy 
Corporation primarily issues unsecured debt.

In 2020, Duke Energy anticipates issuing additional debt of $5.2 billion, 
primarily for the purpose of funding capital expenditures and debt maturities. 

See to Note 7 to the Consolidated Financial Statements, “Debt and Credit 
Facilities,” for further information regarding significant debt issuances in 2019.
Duke Energy’s capitalization is balanced between debt and equity as 

shown in the table below.

Restrictive Debt Covenants

Duke Energy’s debt and credit agreements contain various financial and 

other covenants. Duke Energy’s Master Credit Facility contains a covenant 
requiring the debt-to-total capitalization ratio to not exceed 65% for each 
borrower, excluding Piedmont, and 70% for Piedmont. Failure to meet those 
covenants beyond applicable grace periods could result in accelerated due dates 
and/or termination of the agreements or sublimits thereto. As of December 
31, 2019, each of the Duke Energy Registrants was in compliance with all 
covenants related to their debt agreements. In addition, some credit agreements 
may allow for acceleration of payments or termination of the agreements due to 
nonpayment, or acceleration of other significant indebtedness of the borrower or 
some of its subsidiaries. None of the debt or credit agreements contain material 
adverse change clauses.

Credit Ratings

Moody’s Investors Service, Inc. and S&P provide credit ratings for 
various Duke Energy Registrants. In January 2020, Fitch Ratings, Inc. publicly 
announced plans to withdraw the ratings on Duke Energy Corporation on or 
about February 20, 2020. The following table includes Duke Energy and certain 
subsidiaries’ credit ratings and ratings outlook as of February 2020.

Credit ratings are intended to provide credit lenders a framework for 
comparing the credit quality of securities and are not a recommendation to buy, 
sell or hold. The Duke Energy Registrants’ credit ratings are dependent on the 
rating agencies’ assessments of their ability to meet their debt principal and 
interest obligations when they come due. If, as a result of market conditions 
or other factors, the Duke Energy Registrants are unable to maintain current 
balance sheet strength, or if earnings and cash flow outlook materially 
deteriorates, credit ratings could be negatively impacted.

increases in the current year, partially offset by decreases in current 
year non-cash adjustments;

• a $573 million refund of AMT credit carryforwards;

• a $253 million decrease in cash outflows from working capital primarily 
due to fluctuations in accounts receivable balances, including a prior 

year increase for AMT refunds, and prior year increases in regulatory 
assets related to fuel costs, partially offset by fluctuations in inventory 
levels and current year decreases in property tax and severance 
accruals; and

• a $105 million payment in the prior year for disposal of Beckjord.

Partially offset by:

Off-Balance Sheet Arrangements

Duke Energy and certain of its subsidiaries enter into guarantee 

arrangements in the normal course of business to facilitate commercial 
transactions with third parties. These arrangements include performance 
guarantees, standby letters of credit, debt guarantees, surety bonds and 
indemnifications.

Most of the guarantee arrangements entered into by Duke Energy enhance 

the credit standing of certain subsidiaries, non-consolidated entities or less 
than wholly owned entities, enabling them to conduct business. As such, these 
guarantee arrangements involve elements of performance and credit risk, which 
are not always included on the Consolidated Balance Sheets. The possibility 
of Duke Energy, either on its own or on behalf of Spectra Capital through 
indemnification agreements entered into as part of the January 2, 2007, spin-off 
of Spectra Energy Corp, having to honor its contingencies is largely dependent 
upon the future operations of the subsidiaries, investees and other third parties, 
or the occurrence of certain future events.

Duke Energy performs ongoing assessments of its respective guarantee 

obligations to determine whether any liabilities have been incurred as a result of 
potential increased non-performance risk by third parties for which Duke Energy 

• a $1,551 million decrease in net borrowings from notes payable 

and commercial paper primarily due to the use of proceeds from the 
preferred stock issuance and increased long-term debt issuances used 
to pay down outstanding commercial paper.

has issued guarantees. See Note 8 to the Consolidated Financial Statements, 
“Guarantees and Indemnifications,” for further details of the guarantee 
arrangements. Issuance of these guarantee arrangements is not required for the 
majority of Duke Energy’s operations. Thus, if Duke Energy discontinued issuing 
these guarantees, there would not be a material impact to the consolidated 
results of operations, cash flows or financial position.

In November 2019, Duke Energy executed equity forward sales 

agreements. Settlement of the forward sales agreements are expected to occur 
on or prior to December 31, 2020. See Note 20 to the Consolidated Financial 
Statements, “Stockholders’ Equity” for further details on the equity forward 
sales agreements.

Other than the guarantee arrangements discussed above, the equity 

forward sales agreements and off-balance sheet debt related to non-
consolidated VIEs, Duke Energy does not have any material off-balance sheet 
financing entities or structures. For additional information, see Note 18 to the 
Consolidated Financial Statements, “Variable Interest Entities”.

business, including nuclear insurance (see Note 5 to the Consolidated Financial Statements, “Commitments and Contingencies”), funding of pension and other post-retirement benefit plans (see Note 23 to the Consolidated 
Financial Statements, “Employee Benefit Plans”), AROs, including ash management expenditures (see Note 10 to the Consolidated Financial Statements, “Asset Retirement Obligations”) and regulatory liabilities (see Note 4 
to the Consolidated Financial Statements, “Regulatory Matters”) because the amount and timing of the cash payments are uncertain. Also excluded are Deferred Income Taxes and ITCs recorded on the Consolidated Balance 
Sheets since cash payments for income taxes are determined based primarily on taxable income for each discrete fiscal year.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Risk Management Policies

The Enterprise Risk Management policy framework at Duke Energy 
includes strategy, operational, project execution and financial or transaction 
related risks. Enterprise Risk Management includes market risk as part of the 
financial and transaction related risks in its framework.

Duke Energy is exposed to market risks associated with commodity prices, 

interest rates and equity prices. Duke Energy has established comprehensive 
risk management policies to monitor and manage these market risks. Duke 
Energy’s Chief Executive Officer and Chief Financial Officer are responsible for 
the overall approval of market risk management policies and the delegation 
of approval and authorization levels. The Finance and Risk Management 
Committee of the Board of Directors receives periodic updates from the Chief 
Risk Officer and other members of management on market risk positions, 
corporate exposures and overall risk management activities. The Chief Risk 
Officer is responsible for the overall governance of managing commodity price 
risk, including monitoring exposure limits.

The following disclosures about market risk contain forward-looking 
statements that involve estimates, projections, goals, forecasts, assumptions, 
risks and uncertainties that could cause actual results or outcomes to differ 

materially from those expressed in the forward-looking statements. See 
Item 1A, “Risk Factors,” and “Cautionary Statement Regarding Forward-Looking 
Information” for a discussion of the factors that may impact any such forward-
looking statements made herein.

Commodity Price Risk

Duke Energy is exposed to the impact of market fluctuations in the prices 
of electricity, coal, natural gas and other energy-related products marketed and 
purchased as a result of its ownership of energy-related assets. Duke Energy’s 
exposure to these fluctuations is primarily limited by the cost-based regulation 
of its regulated operations as these operations are typically allowed to recover 
substantially all of these costs through various cost-recovery clauses, including 
fuel clauses, formula-based contracts, or other cost-sharing mechanisms. 
While there may be a delay in timing between when these costs are incurred and 
when they are recovered through rates, changes from year to year generally do 
not have a material impact on operating results of these regulated operations. 
Within Duke Energy’s Commercial Renewables segment, the company has 
limited exposure to market price fluctuations in prices of energy-related 
products as a result of its ownership of renewable assets.

Price risk represents the potential risk of loss from adverse changes in the 
market price of electricity or other energy commodities. Duke Energy’s exposure 
to commodity price risk is influenced by a number of factors, including contract 

52

PART IIsize, length, market liquidity, location and unique or specific contract terms. 
Duke Energy employs established policies and procedures to manage risks 
associated with these market fluctuations, which may include using various 
commodity derivatives, such as swaps, futures, forwards and options. For 
additional information, see Note 15 to the Consolidated Financial Statements, 
“Derivatives and Hedging.”

Hedging Strategies

Duke Energy closely monitors risks associated with commodity price 

changes on its future operations and, where appropriate, uses various 
commodity instruments such as electricity, coal and natural gas forward 
contracts and options to mitigate the effect of such fluctuations on operations. 
Duke Energy’s primary use of energy commodity derivatives is to hedge 
against exposure to the prices of power, fuel for generation and natural gas 
for customers. Additionally, Duke Energy’s Commercial Renewables business 
may enter into short-term or long-term hedge agreements to manage price risk 
associated with project output.

The majority of instruments used to manage Duke Energy’s commodity 
price exposure are either not designated as hedges or do not qualify for hedge 
accounting. These instruments are referred to as undesignated contracts. 
Mark-to-market changes for undesignated contracts entered into by regulated 
businesses are reflected as regulatory assets or liabilities on the Consolidated 
Balance Sheets. Undesignated contracts entered into by unregulated businesses 
are marked-to-market each period, with changes in the fair value of the 
derivative instruments reflected in earnings.

Duke Energy may also enter into other contracts that qualify for the NPNS 
exception. When a contract meets the criteria to qualify as NPNS, Duke Energy 
applies such exception. Income recognition and realization related to NPNS 
contracts generally coincide with the physical delivery of the commodity. For 
contracts qualifying for the NPNS exception, no recognition of the contract’s fair 
value in the Consolidated Financial Statements is required until settlement of 
the contract as long as the transaction remains probable of occurring.

Generation Portfolio Risks

The Duke Energy Registrants optimize the value of their generation 

portfolios, which include generation assets, fuel and emission allowances. 
Modeled forecasts of future generation output and fuel requirements are based 
on forward power and fuel markets. The component pieces of the portfolio 
are bought and sold based on models and forecasts of generation in order to 
manage the economic value of the portfolio in accordance with the strategies of 
the business units.

For the Electric Utilities and Infrastructure segment, the generation 
portfolio not utilized to serve retail operations or committed load is subject 
to commodity price fluctuations. However, the impact on the Consolidated 
Statements of Operations is partially offset by mechanisms in these regulated 
jurisdictions that result in the sharing of net profits from these activities with 
retail customers.

Interest Rate Risk

Duke Energy is exposed to risk resulting from changes in interest rates 
as a result of its issuance or anticipated issuance of variable and fixed-rate 
debt and commercial paper. Duke Energy manages interest rate exposure by 
limiting variable-rate exposures to a percentage of total debt and by monitoring 
the effects of market changes in interest rates. Duke Energy also enters into 
financial derivative instruments, which may include instruments such as, but 
not limited to, interest rate swaps, swaptions and U.S. Treasury lock agreements 
to manage and mitigate interest rate risk exposure. See Notes 1, 7, 15 and 17 
to the Consolidated Financial Statements, “Summary of Significant Accounting 
Policies,” “Debt and Credit Facilities,” “Derivatives and Hedging,” and “Fair 
Value Measurements.”

Duke Energy had $8.6 billion of unhedged long- and short-term floating 
interest rate exposure at December 31, 2019. The impact of a 100-basis point 
change in interest rates on pretax income is approximately $86 million at 
December 31, 2019. This amount was estimated by considering the impact of 
the hypothetical interest rates on variable-rate securities outstanding, adjusted 
for interest rate hedges as of December 31, 2019.

Certain Duke Energy Registrants have variable-rate debt and manage 
interest rate risk by entering into financial contracts including interest rate 
swaps. See Notes 7 and 15 to the Consolidated Financial Statements, 
“Debt and Credit Facilities” and “Derivatives and Hedging.” Such financial 
arrangements generally are indexed based upon LIBOR, which is expected to be 
phased out by the end of 2021. The Secured Overnight Financing Rate (SOFR) 
has been identified by regulators and industry participants as the preferred 
successor rate for U.S. dollar-based LIBOR at that time. Impacted financial 
arrangements extending beyond 2021 may require contractual amendment or 
termination and renegotiation to fully adapt to a post-LIBOR environment, and 
there may be uncertainty regarding the effectiveness of any such alternative 
index methodologies. Alternative index provisions are being assessed and 
incorporated into new financial arrangements that extend beyond 2021. 
Additionally, the progress of the phaseout is being monitored, including proposed 
transition relief from the FASB.

Credit Risk

Credit risk represents the loss that the Duke Energy Registrants would 

incur if a counterparty fails to perform under its contractual obligations. Where 
exposed to credit risk, the Duke Energy Registrants analyze the counterparty’s 
financial condition prior to entering into an agreement and monitor exposure 
on an ongoing basis. The Duke Energy Registrants establish credit limits where 
appropriate in the context of contractual arrangements and monitor such limits.

To reduce credit exposure, the Duke Energy Registrants seek to include 
netting provisions with counterparties, which permit the offset of receivables 
and payables with such counterparties. The Duke Energy Registrants also 
frequently use master agreements with credit support annexes to further 
mitigate certain credit exposures. The master agreements provide for a 
counterparty to post cash or letters of credit to the exposed party for exposure 
in excess of an established threshold. The threshold amount represents a 
negotiated unsecured credit limit for each party to the agreement, determined in 
accordance with the Duke Energy Registrants’ internal corporate credit practices 
and standards. Collateral agreements generally also provide that the failure to 
post collateral when required is sufficient cause to terminate transactions and 
liquidate all positions.

The Duke Energy Registrants also obtain cash, letters of credit, or 
surety bonds from certain counterparties to provide credit support outside of 
collateral agreements, where appropriate, based on a financial analysis of the 
counterparty and the regulatory or contractual terms and conditions applicable 
to each transaction. See Note 15 to the Consolidated Financial Statements, 
“Derivatives and Hedging,” for additional information regarding credit risk 
related to derivative instruments.

The Duke Energy Registrants’ principal counterparties for its electric and 

natural gas businesses are RTOs, distribution companies, municipalities, electric 
cooperatives and utilities located throughout the U.S. Exposure to these entities 
consists primarily of amounts due to Duke Energy Registrants for delivered 
electricity. Additionally, there may be potential risks associated with remarketing 
of energy and capacity in the event of default by wholesale power customers. 
The Duke Energy Registrants have concentrations of receivables from certain of 
such entities that may affect the Duke Energy Registrants’ credit risk.
The Duke Energy Registrants are also subject to credit risk from 

transactions with their suppliers that involve prepayments or milestone 
payments in conjunction with outsourcing arrangements, major construction 
projects and certain commodity purchases. The Duke Energy Registrants’ credit 
exposure to such suppliers may take the form of increased costs or project 
delays in the event of non-performance. The Duke Energy Registrants’ frequently 
require guarantees or letters of credit from suppliers to mitigate this credit risk.

53

PART IICredit risk associated with the Duke Energy Registrants’ service to 
residential, commercial and industrial customers is generally limited to 
outstanding accounts receivable. The Duke Energy Registrants mitigate this 
credit risk by requiring tariff customers to provide a cash deposit, letter of credit 
or surety bond until a satisfactory payment history is established, subject to 
the rules and regulations in effect in each retail jurisdiction at which time the 
deposit is typically refunded. Charge-offs for retail customers have historically 
been insignificant to the operations of the Duke Energy Registrants and are 
typically recovered through retail rates. Management continually monitors 
customer charge-offs and payment patterns to ensure the adequacy of bad 
debt reserves. Duke Energy Ohio and Duke Energy Indiana sell certain of 
their accounts receivable and related collections through CRC, a Duke Energy 
consolidated VIE. Losses on collection are first absorbed by the equity of CRC 
and next by the subordinated retained interests held by Duke Energy Ohio, Duke 
Energy Kentucky and Duke Energy Indiana. See Note 18 to the Consolidated 
Financial Statements, “Variable Interest Entities.” Duke Energy also provides 
certain non-tariff services, primarily to large commercial and industrial 
customers in which incurred costs are intended to be recovered from the 
individual customer and therefore are not subject to rate recovery in the event of 
customer default. Customer credit worthiness is assessed prior to entering into 
these transactions.

Duke Energy’s Commercial Renewables segment enters into long-term 
agreements with certain creditworthy buyers that may not include the right to 
call for collateral in the event of a credit rating downgrade. Credit concentration 
exists to certain counterparties on these agreements, including entities that 
could be subject to wildfire liability. Additionally, Commercial Renewables may 
invest in projects for which buyers are below investment grade, although such 
buyers are required to post negotiated amounts of credit support. Also, power 
sales agreements and/or hedges of project output are generally for an initial 
term that does not cover the entire life of the asset. As a result, Commercial 
Renewables is exposed to market price risk and credit risk related to these 
agreements.

Duke Energy Carolinas has third-party insurance to cover certain 
losses related to asbestos-related injuries and damages above an aggregate 
self-insured retention. See Note 5 to the Consolidated Financial Statements, 
“Commitments and Contingencies” for information on asbestos-related injuries 
and damages claims.

The Duke Energy Registrants also have credit risk exposure through 
issuance of performance and financial guarantees, letters of credit and surety 
bonds on behalf of less than wholly owned entities and third parties. Where 
the Duke Energy Registrants have issued these guarantees, it is possible that 
they could be required to perform under these guarantee obligations in the 
event the obligor under the guarantee fails to perform. Where the Duke Energy 
Registrants have issued guarantees related to assets or operations that have 
been disposed of via sale, they attempt to secure indemnification from the buyer 
against all future performance obligations under the guarantees. See Note 8 to 
the Consolidated Financial Statements, “Guarantees and Indemnifications,” for 
further information on guarantees issued by the Duke Energy Registrants.

Based on the Duke Energy Registrants’ policies for managing credit risk, 

their exposures and their credit and other reserves, the Duke Energy Registrants 
do not currently anticipate a materially adverse effect on their consolidated 
financial position or results of operations as a result of non-performance by any 
counterparty.

OTHER MATTERS

Environmental Regulations

The Duke Energy Registrants are subject to federal, state and local 
regulations regarding air and water quality, hazardous and solid waste disposal, 
coal ash and other environmental matters. These regulations can be changed 
from time to time and result in new obligations of the Duke Energy Registrants.

Marketable Securities Price Risk

As described further in Note 16 to the Consolidated Financial Statements, 

“Investments in Debt and Equity Securities,” Duke Energy invests in debt 
and equity securities as part of various investment portfolios to fund certain 
obligations. The vast majority of investments in equity securities are within the 
NDTF and assets of the various pension and other post-retirement benefit plans.

Pension Plan Assets

Duke Energy maintains investments to facilitate funding the costs of 
providing non-contributory defined benefit retirement and other post-retirement 
benefit plans. These investments are exposed to price fluctuations in equity 
markets and changes in interest rates. The equity securities held in these 
pension plans are diversified to achieve broad market participation and 
reduce the impact of any single investment, sector or geographic region. Duke 
Energy has established asset allocation targets for its pension plan holdings, 
which take into consideration the investment objectives and the risk profile 
with respect to the trust in which the assets are held. See Note 23 to the 
Consolidated Financial Statements, “Employee Benefit Plans,” for additional 
information regarding investment strategy of pension plan assets.

A significant decline in the value of plan asset holdings could require Duke 

Energy to increase funding of its pension plans in future periods, which could 
adversely affect cash flows in those periods. Additionally, a decline in the fair 
value of plan assets, absent additional cash contributions to the plan, could 
increase the amount of pension cost required to be recorded in future periods, 
which could adversely affect Duke Energy’s results of operations in those 
periods.

Nuclear Decommissioning Trust Funds

As required by the NRC, NCUC, PSCSC and FPSC, subsidiaries of Duke 
Energy maintain trust funds to fund the costs of nuclear decommissioning. As 
of December 31, 2019, these funds were invested primarily in domestic and 
international equity securities, debt securities, cash and cash equivalents and 
short-term investments. Per the NRC, Internal Revenue Code, NCUC, PSCSC 
and FPSC requirements, these funds may be used only for activities related to 
nuclear decommissioning. These investments are exposed to price fluctuations 
in equity markets and changes in interest rates. Duke Energy actively monitors 
its portfolios by benchmarking the performance of its investments against 
certain indices and by maintaining, and periodically reviewing, target allocation 
percentages for various asset classes.

Accounting for nuclear decommissioning recognizes that costs are 

recovered through retail and wholesale rates; therefore, fluctuations in 
investment prices do not materially affect the Consolidated Statements of 
Operations, as changes in the fair value of these investments are primarily 
deferred as regulatory assets or regulatory liabilities pursuant to Orders by the 
NCUC, PSCSC, FPSC and FERC. Earnings or losses of the fund will ultimately 
impact the amount of costs recovered through retail and wholesale rates. 
See Note 10 to the Consolidated Financial Statements, “Asset Retirement 
Obligations,” for additional information regarding nuclear decommissioning 
costs. See Note 16 to the Consolidated Financial Statements, “Investments in 
Debt and Equity Securities,” for additional information regarding NDTF assets.

The following sections outline various proposed and recently enacted 
legislation and regulations that may impact the Duke Energy Registrants. Refer 
to Note 4 to the Consolidated Financial Statements, “Regulatory Matters,” for 
further information regarding potential plant retirements and regulatory filings 
related to the Duke Energy Registrants.

PART IICoal Combustion Residuals

Coal Ash Management Act of 2014

In April 2015, EPA published a rule to regulate the disposal of CCR 
from electric utilities as solid waste. The federal regulation classifies CCR as 
nonhazardous waste and allows for beneficial use of CCR with some restrictions. 
The regulation applies to all new and existing landfills, new and existing surface 
impoundments receiving CCR and existing surface impoundments located at 
stations generating electricity (regardless of fuel source), which were no longer 
receiving CCR but contained liquids as of the effective date of the rule. The rule 
establishes requirements regarding landfill design, structural integrity design 
and assessment criteria for surface impoundments, groundwater monitoring, 
protection and remedial procedures and other operational and reporting 
procedures to ensure the safe disposal and management of CCR. Various 
industry and environmental parties appealed EPA’s CCR rule in the D.C. Circuit 
Court. On April 18, 2016, EPA filed a motion with the federal court to settle five 
issues raised in litigation. On June 14, 2016, the court approved the motion 
with respect to all of those issues. Duke Energy does not expect a material 
impact from the settlement or that it will result in additional ARO adjustments. 
On September 13, 2017, EPA responded to a petition by the Utility Solid Waste 
Activities Group that the agency would reconsider certain provisions of the final 
rule, and asked the D.C. Circuit Court to suspend the litigation. The D.C. Circuit 
Court denied EPA’s petition to suspend the litigation and oral argument was held 
on November 20, 2017. On August 21, 2018, the D.C. Circuit issued its decision 
in the CCR rule litigation denying relief for industry petitioners’ remaining claims 
and ruling in favor of environmental petitioners on a number of their challenges, 
including the regulation of inactive CCR surface impoundments at retired plants 
and the continued operation of unlined impoundments.

On March 15, 2018, EPA published proposed amendments to the federal 

CCR rule, including revisions that were required as part of the CCR litigation 
settlement, as well as changes that the agency considered warranted due 
to the passage of the Water Infrastructure Improvements for the Nation Act, 
which provides statutory authority for state and federal CCR permit programs. 
On July 17, 2018, EPA issued a rule (Phase 1, Part 1) finalizing certain, but 
not all, elements included in the agency’s March 15, 2018, proposal. The final 
rule revises certain closure deadlines and groundwater protection standards 
in the CCR rule. It does not change the primary requirements for groundwater 
monitoring, corrective action, inspections and maintenance, and closure, and 
thus does not materially affect Duke Energy’s coal ash basin closure plans or 
compliance obligations under the CCR rule. On October 22, 2018, a coalition 
of environmental groups filed a petition for review in the D.C. Circuit Court 
challenging EPA’s final Phase 1, Part 1 revisions to the CCR rule. On March 13, 
2019, the D.C. Circuit Court issued an order in the Phase 1, Part 1 litigation 
granting EPA’s motion to remand the rule without vacatur. EPA is currently 
conducting multiple notice-and-comment rulemakings to implement the court’s 
decision on remand.

In addition to the requirements of the federal CCR rule, CCR landfills 
and surface impoundments will continue to be regulated by most states. Cost 
recovery for future expenditures will be pursued through the normal ratemaking 
process with federal and state utility commissions and via wholesale contracts, 
which permit recovery of necessary and prudently incurred costs associated 
with Duke Energy’s regulated operations. For more information, see Notes 4 and 
10 to the Consolidated Financial Statements, “Regulatory Matters” and “Asset 
Retirement Obligations,” respectively.

AROs recorded on the Duke Energy Carolinas and Duke Energy Progress 
Consolidated Balance Sheets at December 31, 2019, and December 31, 2018, 
include the legal obligation for closure of coal ash basins and the disposal 
of related ash as a result of the Coal Ash Act, the EPA CCR rule and other 
agreements. The Coal Ash Act includes a variance procedure for compliance 
deadlines and other issues surrounding the management of CCR and CCR 
surface impoundments and prohibits cost recovery in customer rates for 
unlawful discharge of ash impoundment waters occurring after January 1, 2014. 
The Coal Ash Act leaves the decision on cost recovery determinations related to 
closure of ash impoundments to the normal ratemaking processes before utility 
regulatory commissions.

Consistent with the requirements of the Coal Ash Act, Duke Energy 
previously submitted comprehensive site assessments and groundwater 
corrective plans to NCDEQ. In addition, on December 31, 2019, Duke Energy 
submitted updated groundwater corrective action plans and site-specific coal 
ash impoundment closure plans to NCDEQ.

On April 1, 2019, NCDEQ issued a closure determination requiring Duke 
Energy Carolinas and Duke Energy Progress to excavate all remaining coal ash 
impoundments at the Allen, Belews Creek, Rogers, Marshall, Mayo and Roxboro 
facilities in North Carolina. On April 26, 2019, Duke Energy Carolinas and 
Duke Energy Progress filed Petitions for Contested Case Hearings in the Office 
of Administrative Hearings to challenge NCDEQ’s April 1 Order. On December 
31, 2019, Duke Energy Carolinas and Duke Energy Progress entered into a 
settlement agreement with NCDEQ and certain community groups under which 
Duke Energy Carolinas and Duke Energy Progress agreed to excavate seven of 
the nine remaining coal ash basins at these sites with ash moved to on-site 
lined landfills, including two at Allen, one at Belews Creek, one at Mayo, one 
at Roxboro, and two at Rogers. At the two remaining basins at Marshall and 
Roxboro, uncapped basin ash will be excavated and moved to lined landfills. 
Those portions of the basins at Marshall and Roxboro, which were previously 
filled with ash and on which permitted facilities were constructed, will not 
be disturbed and will be closed pursuant to other state regulations. For more 
information, see Note 5, “Commitments and Contingencies,” to the Consolidated 
Financial Statements.

Following NCDEQ’s April 1 Order, Duke Energy estimated the incremental 

undiscounted cost to close the nine remaining impoundments by excavation 
would be approximately $4 billion to $5 billion, potentially increasing the total 
estimated costs to permanently close all ash basins in North Carolina and South 
Carolina to $9.5 billion to $10.5 billion. The settlement lowers the estimated 
total undiscounted cost to close the nine remaining basins by excavation by 
approximately $1.5 billion as compared to Duke Energy’s original estimate that 
followed the order. As a result, the estimated total cost to permanently close all 
ash basins in North Carolina and South Carolina is now approximately $8 billion 
to $9 billion, of which approximately $2.3 billion has been spent through 2019. 
The majority of the remaining spend is expected to occur over the next 15-20 
years. Duke Energy intends to seek recovery of all costs through the ratemaking 
process consistent with previous proceedings.

In 2019, Duke Energy completed excavation of all coal ash at the 
Riverbend and Dan River plants and coal ash regulated by the Coal Ash Act at 
the Sutton plant.

For further information on ash basins and recovery, see Notes 4 and 10 

to the Consolidated Financial Statements, “Regulatory Matters” and “Asset 
Retirement Obligations,” respectively.

PART IIEstimated Cost and Impacts of Rulemakings

Duke Energy will incur capital expenditures to comply with the 
environmental regulations and rules discussed above. The following table, as 
of December 31, 2019, provides five-year estimated costs, excluding AFUDC, 
of new control equipment that may need to be installed on existing power 
plants primarily to comply with the Coal Ash Act requirements for conversion 
to dry disposal of bottom ash and fly ash, CWA 316(b) and Effluent Limitations 
Guidelines through December 31, 2024. The table excludes ash basin closure 
costs recorded in Asset retirement obligations on the Consolidated Balance 
Sheets. For more information related to AROs, see Note 10 to the Consolidated 
Financial Statements.

The Duke Energy Registrants also expect to incur increased fuel, 
purchased power, operation and maintenance and other expenses, in 
addition to costs for replacement generation for potential coal-fired power 
plant retirements, as a result of these regulations. Actual compliance costs 
incurred may be materially different from these estimates due to reasons 
such as the timing and requirements of EPA regulations and the resolution of 
legal challenges to the rules. The Duke Energy Registrants intend to seek rate 
recovery of necessary and prudently incurred costs associated with regulated 
operations to comply with these regulations.

Other Environmental Regulations

The Duke Energy Registrants are also subject to various federal, state and 

local laws regarding air and water quality, hazardous and solid waste disposal 
and other environmental matters, including the following:

• Clean Water Act

• Steam Effluent Limitation Guidelines

• Cross-State Air Pollution Rule

• Clean Power Plan/ACE Rule

Duke Energy continues to comply with enacted environmental statutes 
and regulations even as certain of these regulations are in various stages of 
clarification, revision or legal challenge. The Duke Energy Registrants cannot 
predict the outcome of these matters.

Section 126 Petitions

On November 16, 2016, the state of Maryland filed a petition with EPA 

under Section 126 of the Clean Air Act alleging that 19 power plants, including 
two plants (three units) that Duke Energy Registrants own and operate, 
contribute to violations of EPA’s National Ambient Air Quality Standards (NAAQS) 
for ozone in the state of Maryland. On March 12, 2018, the state of New York 
filed a petition with EPA, also under Section 126 of the Clean Air Act alleging 
that over 60 power plants, including six that Duke Energy Registrants own and 
operate, contribute to violations of EPA’s ozone NAAQS in the state of New York. 
Both Maryland and New York sought EPA orders requiring the states in which the 
named power plants operate impose more stringent NOx emission limitations 
on the plants. On October 5, 2018, EPA denied the Maryland petition. That same 
day, Maryland appealed EPA’s denial, On October 18, 2019, EPA denied the New 
York petition, and New York appealed that decision on October 29, 2019. Both 

56

appeals are before the D.C. Circuit Court. The impact of these petitions could 
be more stringent requirements for the operation of NOx emission controls at 
these plants. The Duke Energy Registrants cannot predict the outcome of these 
matters.

Global Climate Change

On September 17, 2019, Duke Energy announced an updated climate 
strategy with a new goal of net-zero carbon emissions from electric generation 
by 2050. Timelines and initiatives, as well as implementation of new 
technologies, will vary in each state in which the company operates and will 
involve collaboration with regulators, customers and other stakeholders.

The Duke Energy Registrants’ GHG emissions consist primarily of CO2 
and result primarily from operating a fleet of coal-fired and natural gas-fired 
power plants. In 2019, the Duke Energy Registrants’ power plants emitted 
approximately 93 million tons of CO2. Future levels of CO2 emissions will be 
influenced by variables that include fuel prices, market prices, compliance with 
new or existing regulations, economic conditions that affect electricity demand 
and the technologies deployed to generate the electricity necessary to meet the 
customer demand.

The Duke Energy Registrants have taken actions that have resulted in a 
reduction of CO2 emissions over time. Actions have included the retirement of 
47 coal-fired Electric Generating Units with a combined generating capacity of 
5,425 MW. Much of that capacity has been replaced with state-of-the-art highly 
efficient natural gas-fired generation that produces far fewer CO2 emissions 
per unit of electricity generated. Duke Energy also has made investments 
to expand its portfolio of wind and solar projects, increase EE offerings and 
invest in its zero-CO2 emissions hydropower and nuclear plants. These efforts 
have diversified its system and significantly reduced CO2 emissions. Between 
2005 and 2019, the Duke Energy Registrants have collectively lowered the CO2 
emissions from their electricity generation by 39%, which potentially lowers 
the exposure to any future mandatory CO2 emission reduction requirements 
or carbon tax, whether as a result of federal legislation, EPA regulation, 
state regulation or other as yet unknown emission reduction requirement. 
Duke Energy will continue to explore the use of currently available and 
commercially demonstrated technology to reduce CO2 emissions, including 
EE, wind, solar, storage and nuclear. Duke Energy will adjust to evolving and 
innovative technologies in a way that balances the reliability and affordability 
that customers expect. Under any future scenario involving mandatory CO2 
limitations, the Duke Energy Registrants would plan to seek recovery of their 
compliance costs through appropriate regulatory mechanisms.

The Duke Energy Registrants recognize certain groups associate severe 
weather events with increasing levels of GHGs in the atmosphere and forecast 
the possibility these weather events could have a material impact on future 
results of operations should they occur more frequently and with greater 
severity. However, the uncertain nature of potential changes in extreme weather 
events (such as increased frequency, duration and severity), the long period 
of time over which any potential changes might take place and the inability 
to predict potential changes with any degree of accuracy, make estimating 
any potential future financial risk to the Duke Energy Registrants’ operations 
impossible.

The Duke Energy Registrants annually, biennially or triennially prepare 

lengthy, forward-looking IRPs. These detailed, highly technical plans are based 
on the company’s thorough analysis of numerous factors that can impact the 
cost of producing and delivering electricity that influence long-term resource 
planning decisions. The IRP process helps to evaluate a range of options, taking 
into account forecasts of future electricity demand, fuel prices, transmission 
improvements, new generating capacity, integration of renewables, energy 
storage, EE and demand response initiatives. The IRP process also helps 
evaluate potential environmental and regulatory scenarios to better mitigate 
policy and economic risks. The IRPs we file with regulators look out 10 to 
20 years depending on the jurisdiction.

PART IIFor a number of years, the Duke Energy Registrants have included a price 

on CO2 emissions in their IRP planning process to account for the potential 
regulation of CO2 emissions. Incorporating a price on CO2 emissions in the 
IRPs allows for the evaluation of existing and future resource needs against 
potential climate change policy risk in the absence of policy certainty. One 
of the challenges with using a CO2 price, especially in the absence of a clear 
and certain policy, is determining the appropriate price to use. To address this 
uncertainty and ensure the company remains agile, the Duke Energy Registrants 
typically use a range of potential CO2 prices to reflect a range of potential policy 
outcomes.

The Duke Energy Registrants routinely take steps to reduce the potential 

impact of severe weather events on their electric distribution systems by 
modernizing the electric grid through smart meters, storm hardening, self-
healing and targeted undergrounding and applying lessons learned from 
previous storms to restoration efforts. The Duke Energy Registrants’ electric 
generating facilities are designed to withstand extreme weather events without 
significant damage. The Duke Energy Registrants maintain an inventory of coal 
and oil on-site to mitigate the effects of any potential short-term disruption in 
fuel supply so they can continue to provide customers with an uninterrupted 
supply of electricity.

State Legislation

of costs related to the competitive bidding process through the fuel clause and 
a competitive procurement rider.

In accordance with the provisions of HB 589, total procurement was 
changed based upon how much generation with no economic dispatch or 
curtailment occurs over the procurement period. Most of this type of generation 
is solar procured under PURPA. Based upon the current forecasted amount of 
such generation that will occur over procurement period, Duke Energy estimates 
the total under HB 589 competitive procurement will be approximately 1,500 to 
2,000 MW.

Based on an independent evaluation process, Duke Energy will own 

or purchase a total of 551 MW of renewable energy from projects under the 
North Carolina’s CPRE program. The process used was approved by the NCUC 
to select projects that would deliver the lowest cost renewable energy for 
customers. Five Duke Energy projects, totaling about 190 MW, were selected 
during the competitive bidding process. Duke Energy has completed the 
contracting process for the winning projects. A second tranche for CPRE opened 
in October 2019 and bids are due by March 9, 2020; the current target date for 
execution of the contracts is the fourth quarter of 2020.

In various states, legislation is being considered to allow third-party sales 

of electricity. Deregulation or restructuring in the electric industry may result 
in increased competition and unrecovered costs. The Duke Energy Registrants 
cannot predict the outcome of these initiatives.

In July 2017, the North Carolina General Assembly passed House Bill 
589, and it was subsequently signed into law by the governor. The law includes, 
among other things, overall reform of the application of PURPA for new solar 
projects in the state, a requirement for the utility to procure approximately 2,600 
MW of renewable energy through a competitive bidding process and recovery

PART IIREPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the shareholders and the Board of Directors of  
Duke Energy Corporation

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Duke Energy Corporation and subsidiaries (the “Company”) as of December 31, 2019 and 
2018, the related consolidated statements of operations, comprehensive income, changes in equity, and cash flows, for each of the three years in the period ended 
December 31, 2019, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material 
respects, the financial position of the Company as of December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the three years in 
the period ended December 31, 2019, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal 

control over financial reporting as of December 31, 2019, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of 
Sponsoring Organizations of the Treadway Commission and our report dated February 20, 2020, expressed an unqualified opinion on the Company’s internal control 
over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial 
statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in 
accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable 
assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to 
assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such 
procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the 
accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that 
our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current-period audit of the financial statements that were communicated or 

required to be communicated to the audit committee and that (1) relate to accounts or disclosures that are material to the financial statements and (2) involved 
our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial 
statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the 
accounts or disclosures to which they relate.

Investment in Unconsolidated Affiliates - Equity Method Investments - Refer to Notes 4 and 13 to the financial statements.

Critical Audit Matter Description

Investments in affiliates that are not controlled by the Company but over which the Company has significant influence are accounted for using the equity 
method of accounting. Equity method investments are assessed for impairment whenever events or changes in circumstances indicate that the carrying amount of the 
investment may not be recoverable. If the decline in value is considered to be other than temporary, the investment is written down to its estimated fair value, which 
establishes a new cost basis in the investment.

At December 31, 2019, the carrying value of the equity method investment in Atlantic Coast Pipeline, LLC (ACP) was $1.2 billion. ACP has received several 
adverse court rulings, and as a result, the Company evaluated this investment for impairment. The Company has determined that fair value approximates carrying 
value and, therefore, concluded the investment is not impaired. The Company used probability-weighted outcome scenarios of discounted future cash flows to 
estimate the fair value of the investment. The use of probability-weighted, discounted cash flows requires management to make significant estimates regarding the 
likelihood of various scenarios, the key assumptions including total construction cost and revenues, and the discount rate utilized to determine the fair value estimate. 
Changes in these assumptions could have a significant impact on the fair value estimate, which is used to determine the amount of any impairment.

We identified the impairment evaluation of ACP as a critical audit matter because of the significant estimates and assumptions management makes related to 

the probability-weighted, discounted cash flows. The audit procedures to evaluate the reasonableness of management’s estimates and assumptions related to the 
likelihood of various scenarios, the key assumptions including total construction cost and revenues, and the discount rate required a high degree of auditor judgement 
and an increased extent of effort, including the need to involve our fair value specialists.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the discounted, probability-weighted forecasts of future cash flows and determination of the fair value of the ACP equity method 

investment, included the following, among others:

• We tested the effectiveness of controls over the accounting for the ACP equity method investment, including those over the development of the fair value 

estimate.

59

PART II• We evaluated the likelihood of the various outcomes used by management to develop the probability-weighted scenarios of future cash flows by:

 ◦ Obtaining letters and making inquiries from the ACP’s internal and external legal counsel regarding likely outcomes of future court rulings

 ◦ Reading information included in the Company’s and the project manager’s press releases, regulatory filings and orders, legal briefs and orders, and analyst 

and industry reports

 ◦ Reading internal communications to management and the Board of Directors

 ◦ Comparing the various scenarios to scenarios previously developed by management

• We evaluated the reasonableness of the key assumptions used to develop the scenarios of future cash flows by comparing key assumptions to: 

 ◦ Internal communications and schedules to management and the Board of Directors

 ◦ Information included in the Company’s and the project manager’s press releases, regulatory filings and related orders

 ◦ Industry reports and external transaction data

 ◦ Executed contracts and invoices

• With the assistance of our fair value specialists, we evaluated the reasonableness of the (1) valuation methodology and (2) discount rate used to develop the 

fair value estimate by:

 ◦ Determining the appropriateness of the valuation methodology by comparing management’s methodology to generally accepted valuation practice

 ◦ Testing the mathematical accuracy of the fair value estimate

 ◦ Testing the source information underlying the determination of the discount rate

 ◦ Developing a range of independent estimates of the discount rate and comparing those to the discount rate selected by management

Regulatory Matters - Impact of Rate Regulation on the Financial Statements - Refer to Notes 1, 4, and 10 to the financial statements.

Critical Audit Matter Description

The Company is subject to regulation by federal and state utility regulatory agencies (the “Commissions”), which have jurisdiction with respect to the rates 

of the Company’s electric and natural gas distribution companies. Management has determined it meets the criteria for the application of regulated operations 
accounting in preparing its financial statements under accounting principles generally accepted in the United States of America. Significant judgment can be required 
to determine if otherwise recognizable incurred costs qualify to be presented as a regulatory asset and deferred because such costs are probable of future recovery in 
customer rates. As of December 31, 2019, the Company has $15 billion recorded as regulatory assets.

We identified the impact of rate regulation as a critical audit matter due to the significant judgments made by management, including assumptions regarding the 

outcome of future decisions by the Commissions, to support its assertions on the likelihood of future recovery for deferred costs. As such, auditing these judgments 
required specialized knowledge of accounting for rate regulation due to its inherent complexities, a high degree of auditor judgment, and an increased extent of effort.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the recovery of regulatory assets included the following, among others:

• We tested the effectiveness of management’s controls over the evaluation of the likelihood of the recovery in future rates of regulatory assets and the 

monitoring and evaluation of regulatory developments that may affect the likelihood of recovering costs in future rates.

• We evaluated the Company’s disclosures related to the impacts of rate regulation, including the balances recorded and regulatory developments.

• We read relevant regulatory orders issued by the Commissions, regulatory statutes, interpretations, procedural memorandums, filings made by interveners, 

and other publicly available information to assess the likelihood of recovery in future rates based on precedence of the Commission’s treatment of 
similar costs under similar circumstances. We evaluated the external information and compared to management’s recorded regulatory asset balances for 
completeness.

• For regulatory matters in process, we inspected the Company’s and intervenors’ filings with the Commissions that may impact the Company’s future rates, 

for any evidence that might contradict management’s assertions.

• We performed audit procedures on the incurred costs requested for recovery to confirm their completeness and accuracy. 

• We obtained an analysis from management and letters from internal and external legal counsel, as appropriate, regarding probability of recovery for regulatory 

assets not yet addressed in a regulatory order to assess management’s assertion that amounts are probable of recovery.

PART IIREPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholder and the Board of  
Directors of Duke Energy Carolinas, LLC

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Duke Energy Carolinas, LLC and subsidiaries (the “Company”) as of December 31, 2019 

and 2018, the related consolidated statements of operations and comprehensive income, changes in equity, and cash flows, for each of the three years in the period 
ended December 31, 2019, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in 
all material respects, the financial position of the Company as of December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the 
three years in the period ended December 31, 2019, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial 
statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are 
required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities 
and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable 
assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we 
engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over 
financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we 
express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and 
performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the 
financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the 
overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Progress Energy, Inc. and subsidiaries (the “Company”) as of December 31, 2019 and 2018, 

the related consolidated statements of operations and comprehensive income, changes in equity, and cash flows, for each of the three years in the period ended

respects, the financial position of the Company as of December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the three years in 
the period ended December 31, 2019, in conformity with accounting principles generally accepted in the United States of America.

PART IIREPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholder and the Board of  
Directors of Duke Energy Progress, LLC

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Duke Energy Progress, LLC and subsidiaries (the “Company”) as of December 31, 2019 

and 2018, the related consolidated statements of operations and comprehensive income, changes in equity, and cash flows, for each of the three years in the period 
ended December 31, 2019, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in 
all material respects, the financial position of the Company as of December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the 
three years in the period ended December 31, 2019, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial 
statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are 
required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities 
and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable 
assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we 
engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over 
financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we 
express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and 
performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the 
financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the 
overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

PART IIREPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholder and the Board of  
Directors of Duke Energy Ohio, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Duke Energy Ohio, Inc. and subsidiaries (the “Company”) as of December 31, 2019 and 

2018, the related consolidated statements of operations and comprehensive income, changes in equity, and cash flows, for each of the three years in the period 
ended December 31, 2019, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all 
material respects, the financial position of the Company as of December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the three 
years in the period ended December 31, 2019, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial 
statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are 
required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities 
and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable 
assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we 
engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over 
financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we 
express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and 
performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the 
financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the 
overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

PART IIREPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholder and the Board of Directors of  
Piedmont Natural Gas Company, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Piedmont Natural Gas Company, Inc. and subsidiaries (the “Company”) as of December 31, 

2019 and 2018, the related consolidated statements of operations and comprehensive income, changes in equity, and cash flows, for each of the three years in the 
period ended December 31, 2019, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, 
in all material respects, the financial position of the Company as of December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the 
three years in the period ended December 31, 2019, in conformity with accounting principles generally accepted in the United States of America.

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial 
statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are 
required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities 
and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable 
assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we 
engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over 
financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we 
express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and 
performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the 
financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the 
overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Tables within the notes may not sum across due to (i) Progress Energy’s consolidation of Duke Energy Progress, Duke Energy Florida and other subsidiaries that 

are not registrants and (ii) subsidiaries that are not registrants but included in the consolidated Duke Energy balances.

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NATURE OF OPERATIONS AND BASIS OF CONSOLIDATION

Duke Energy is an energy company headquartered in Charlotte, 

North Carolina, subject to regulation by the FERC and other regulatory agencies 
listed below. Duke Energy operates in the U.S. primarily through its direct and 
indirect subsidiaries. Certain Duke Energy subsidiaries are also subsidiary 
registrants, including Duke Energy Carolinas; Progress Energy; Duke Energy 
Progress; Duke Energy Florida; Duke Energy Ohio; Duke Energy Indiana and 
Piedmont. When discussing Duke Energy’s consolidated financial information, 
it necessarily includes the results of its separate Subsidiary Registrants, 
which along with Duke Energy, are collectively referred to as the Duke Energy 
Registrants.

The information in these combined notes relates to each of the Duke 

Energy Registrants as noted in the Index to Combined Notes to Consolidated 
Financial Statements. However, none of the Subsidiary Registrants make any 
representation as to information related solely to Duke Energy or the Subsidiary 
Registrants of Duke Energy other than itself.

These Consolidated Financial Statements include, after eliminating 
intercompany transactions and balances, the accounts of the Duke Energy 
Registrants and subsidiaries or VIEs where the respective Duke Energy 
Registrants have control. See Note 18 for additional information on VIEs. These 
Consolidated Financial Statements also reflect the Duke Energy Registrants’ 
proportionate share of certain jointly owned generation and transmission 
facilities. See Note 9 for additional information on joint ownership. Substantially 
all of the Subsidiary Registrants’ operations qualify for regulatory accounting.
Duke Energy Carolinas is a regulated public utility primarily engaged in 
the generation, transmission, distribution and sale of electricity in portions of 
North Carolina and South Carolina. Duke Energy Carolinas is subject to the 
regulatory provisions of the NCUC, PSCSC, NRC and FERC.

Progress Energy is a public utility holding company, which conducts 

operations through its wholly owned subsidiaries, Duke Energy Progress and 
Duke Energy Florida. Progress Energy is subject to regulation by FERC and other 
regulatory agencies listed below.

Duke Energy Progress is a regulated public utility primarily engaged in 
the generation, transmission, distribution and sale of electricity in portions 
of North Carolina and South Carolina. Duke Energy Progress is subject to the 
regulatory provisions of the NCUC, PSCSC, NRC and FERC.

transmission and distribution of electricity in portions of Ohio and Kentucky, the 
generation and sale of electricity in portions of Kentucky and the transportation 
and sale of natural gas in portions of Ohio and Kentucky. Duke Energy Ohio 
conducts competitive auctions for retail electricity supply in Ohio whereby 
the energy price is recovered from retail customers and recorded in Operating 
Revenues on the Consolidated Statements of Operations and Comprehensive 
Income. Operations in Kentucky are conducted through its wholly owned 
subsidiary, Duke Energy Kentucky. References herein to Duke Energy Ohio 
collectively include Duke Energy Ohio and its subsidiaries, unless otherwise 
noted. Duke Energy Ohio is subject to the regulatory provisions of the PUCO, 
KPSC and FERC.

Duke Energy has elected to present cash flows of discontinued operations 

combined with cash flows of continuing operations. Unless otherwise noted, 
the notes to these consolidated financial statements exclude amounts related 
to discontinued operations for all periods presented. See Note 2 for additional 
information.

Amounts Attributable to Controlling Interests

For the years ended December 31, 2019, 2018 and 2017, the Income 
(Loss) From Discontinued Operations, net of tax on Duke Energy’s Consolidated 
Statements of Operations is entirely attributable to controlling interest.

Noncontrolling Interest

Duke Energy maintains a controlling financial interest in certain less-than 
wholly owned non-regulated subsidiaries. As a result, Duke Energy consolidates 
these subsidiaries and presents the third-party investors’ portion of Duke 
Energy’s net income (loss), net assets and comprehensive income (loss) as 
noncontrolling interest. Noncontrolling interest is included as a component of 
equity on the Consolidated Balance Sheet.

Several operating agreements of Duke Energy’s subsidiaries with 

noncontrolling interest are subject to allocations of tax attributes and cash flows 
in accordance with contractual agreements that vary throughout the lives of 
the subsidiaries. Therefore, Duke Energy and the other investors’ (the owners) 
interests in the subsidiaries are not fixed, and the subsidiaries apply the HLBV 
method in allocating income or loss and other comprehensive income or loss 
(all measured on a pretax basis) to the owners. The HLBV method measures 
the amounts that each owner would hypothetically claim at each balance sheet 
reporting date, including tax benefits realized by the owners, upon a hypothetical 
liquidation of the subsidiary at the net book value of its underlying assets. 
The change in the amount that each owner would hypothetically receive at the 

reporting date compared to the amount it would have received on the previous 
reporting date represents the amount of income or loss allocated to each owner 
for the reporting period. During 2019, Duke Energy received $428 million for 
the sale of noncontrolling interests to tax equity members subject to the HLBV 
method for projects totaling 718 MW in nameplate capacity. Duke Energy 
allocated approximately $165 million of losses to noncontrolling tax equity 
members utilizing the HLBV method for the year ended December 31, 2019.
Other operating agreements of Duke Energy’s subsidiaries with 
noncontrolling interest allocate profit and loss based on their pro rata shares 
of the ownership interest in the respective subsidiary. Therefore, Duke Energy 
allocates net income or loss and other comprehensive income or loss of these 
subsidiaries to the owners based on their pro rata shares.

During the third quarter of 2019, Duke Energy completed a sale of 
minority interest in a portion of certain renewable assets to John Hancock. John 
Hancock’s ownership interest in the assets represents a noncontrolling interest. 
See Note 2 for additional information on the sale.

SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates

In preparing financial statements that conform to GAAP, the Duke Energy 

Registrants must make estimates and assumptions that affect the reported 
amounts of assets and liabilities, the reported amounts of revenues and 
expenses and the disclosure of contingent assets and liabilities at the date of 
the financial statements. Actual results could differ from those estimates.

Regulatory Accounting

The majority of the Duke Energy Registrants’ operations are subject 
to price regulation for the sale of electricity and natural gas by state utility 
commissions or FERC. When prices are set on the basis of specific costs 
of the regulated operations and an effective franchise is in place such that 
sufficient natural gas or electric services can be sold to recover those costs, 
the Duke Energy Registrants apply regulatory accounting. Regulatory accounting 
changes the timing of the recognition of costs or revenues relative to a company 
that does not apply regulatory accounting. As a result, regulatory assets and 
regulatory liabilities are recognized on the Consolidated Balance Sheets. 
Regulatory assets and liabilities are amortized consistent with the treatment of 
the related cost in the ratemaking process. See Note 4 for further information.
Regulatory accounting rules also require recognition of a disallowance 
(also called “impairment”) loss if it becomes probable that part of the cost of a 
plant under construction (or a recently completed plant or an abandoned plant) 
will be disallowed for ratemaking purposes and a reasonable estimate of the 
amount of the disallowance can be made. For example, if a cost cap is set for 
a plant still under construction, the amount of the disallowance is a result of a 
judgment as to the ultimate cost of the plant. These disallowances can require 
judgments on allowed future rate recovery.

When it becomes probable that regulated generation, transmission or 
distribution assets will be abandoned, the cost of the asset is removed from 
plant in service. The value that may be retained as a regulatory asset on the 
balance sheet for the abandoned property is dependent upon amounts that 
may be recovered through regulated rates, including any return. As such, 
an impairment charge could be partially or fully offset by the establishment 
of a regulatory asset if rate recovery is probable. The impairment charge 
for a disallowance of costs for regulated plants under construction, recently 
completed or abandoned is based on discounted cash flows.

The Duke Energy Registrants utilize cost-tracking mechanisms, commonly 

Cash, Cash Equivalents and Restricted Cash

referred to as fuel adjustment clauses or PGA clauses. These clauses allow 
for the recovery of fuel and fuel-related costs, portions of purchased power, 
natural gas costs and hedging costs through surcharges on customer rates. The 
difference between the costs incurred and the surcharge revenues is recorded 
either as an adjustment to Operating Revenues, Operating Expenses – Fuel 
used in electric generation or Operating Expenses – Cost of natural gas on the 
Consolidated Statements of Operations, with an off-setting impact on regulatory 
assets or liabilities.

All highly liquid investments with maturities of three months or less at 

the date of acquisition are considered cash equivalents. Duke Energy, Progress 
Energy and Duke Energy Florida have restricted cash balances related primarily 
to collateral assets, escrow deposits and VIEs. See Note 18 for additional 
information. Restricted cash amounts are included in Other within Current 
Assets and Other Noncurrent Assets on the Consolidated Balance Sheets. 
The following table presents the components of cash, cash equivalents and

Inventory

Inventory related to regulated operations is valued at historical cost. Inventory related to nonregulated operations is valued at the lower of cost or market. 
Inventory is charged to expense or capitalized to property, plant and equipment when issued, primarily using the average cost method. Excess or obsolete inventory is 
written-down to the lower of cost or net realizable value. Once inventory has been written-down, it creates a new cost basis for the inventory that is not subsequently 
written-up. Provisions for inventory write-offs were not material at December 31, 2019, and 2018, respectively. The components of inventory are presented in the

Investments in Debt and Equity Securities

The Duke Energy Registrants classify investments in equity securities as 
FV-NI and investments in debt securities as AFS. Both categories are recorded 
at fair value on the Consolidated Balance Sheets. Realized and unrealized gains 
and losses on securities classified as FV-NI are reported through net income. 
Unrealized gains and losses for debt securities classified as AFS are included 
in AOCI until realized, except OTTIs that are included in earnings immediately. 
At the time gains and losses for debt securities are realized, they are reported 
through net income. For certain investments of regulated operations, such as 
substantially all of the NDTF, realized and unrealized gains and losses (including 
any OTTIs) on debt securities are recorded as a regulatory asset or liability. The 
credit loss portion of debt securities of nonregulated operations are included 
in earnings. Investments in debt and equity securities are classified as either 
current or noncurrent based on management’s intent and ability to sell these 
securities, taking into consideration current market liquidity. See Note 16 for 
further information.

Goodwill

Duke Energy, Progress Energy, Duke Energy Ohio and Piedmont perform 
annual goodwill impairment tests as of August 31 each year at the reporting unit 
level, which is determined to be a business segment or one level below. Duke 
Energy, Progress Energy, Duke Energy Ohio and Piedmont update these tests 
between annual tests if events or circumstances occur that would more likely 
than not reduce the fair value of a reporting unit below its carrying value. See 
Note 12 for further information.

Intangible Assets

Intangible assets are included in Other in Other Noncurrent Assets on the 
Consolidated Balance Sheets. Generally, intangible assets are amortized using 
an amortization method that reflects the pattern in which the economic benefits 
of the intangible asset are consumed or on a straight-line basis if that pattern is 
not readily determinable. Amortization of intangibles is reflected in Depreciation 
and amortization on the Consolidated Statements of Operations. Intangible 
assets are subject to impairment testing and if impaired, the carrying value is 
accordingly reduced.

Emission allowances permit the holder of the allowance to emit certain 

gaseous byproducts of fossil fuel combustion, including SO2 and NOX. 
Allowances are issued by the EPA at zero cost and may also be bought and sold 
via third-party transactions. Allowances allocated to or acquired by the Duke 
Energy Registrants are held primarily for consumption. Carrying amounts for 
emission allowances are based on the cost to acquire the allowances. Emission 
allowances are expensed to Fuel used in electric generation and purchased 
power on the Consolidated Statements of Operations.

RECs are used to measure compliance with renewable energy standards 

and are held primarily for consumption. See Note 12 for further information.

weighted. If the carrying value of the long-lived asset is not recoverable 
based on these estimated future undiscounted cash flows, the carrying value 
of the asset is written-down to its then-current estimated fair value and an 
impairment charge is recognized.

The Duke Energy Registrants assess fair value of long-lived assets using 

various methods, including recent comparable third-party sales, internally 
developed discounted cash flow analysis and analysis from outside advisors. 
Triggering events to reassess cash flows may include, but are not limited 
to, significant changes in commodity prices, the condition of an asset or 
management’s interest in selling the asset.

Equity Method Investment Impairments

Investments in affiliates that are not controlled by Duke Energy, but over 
which it has significant influence, are accounted for using the equity method. 
Equity method investments are assessed for impairment whenever events or 
changes in circumstances indicate that the carrying amount of the investment 
may not be recoverable. If the decline in value is considered to be other than 
temporary, the investment is written down to its estimated fair value, which 
establishes a new cost basis in the investment.

Impairment assessments use a discounted cash flow income approach 
and include consideration of the severity and duration of any decline in the fair 
value of the investments. The estimated cash flows may be based on alternative 
expected outcomes that are probability weighted. Key inputs that involve 
estimates and significant management judgment include cash flow projections, 
selection of a discount rate, probability weighting of potential outcomes, and 
whether any decline in value is considered temporary.

Property, Plant and Equipment

Property, plant and equipment are stated at the lower of depreciated 
historical cost net of any disallowances or fair value, if impaired. The Duke 
Energy Registrants capitalize all construction-related direct labor and material 
costs, as well as indirect construction costs such as general engineering, taxes 
and financing costs. See “Allowance for Funds Used During Construction and 
Interest Capitalized” for information on capitalized financing costs. Costs of 
renewals and betterments that extend the useful life of property, plant and 
equipment are also capitalized. The cost of repairs, replacements and major 
maintenance projects, which do not extend the useful life or increase the 
expected output of the asset, are expensed as incurred. Depreciation is generally 
computed over the estimated useful life of the asset using the composite 
straight-line method. Depreciation studies are conducted periodically to update 
composite rates and are approved by state utility commissions and/or the FERC 
when required. The composite weighted average depreciation rates, excluding 
nuclear fuel, are included in the table that follows.

Long-Lived Asset Impairments

The Duke Energy Registrants evaluate long-lived assets, excluding 
goodwill, for impairment when circumstances indicate the carrying value of 
those assets may not be recoverable. An impairment exists when a long-lived 
asset’s carrying value exceeds the estimated undiscounted cash flows expected 
to result from the use and eventual disposition of the asset. The estimated 
cash flows may be based on alternative expected outcomes that are probability

PART IIDUKE ENERGY CORPORATION • DUKE ENERGY CAROLINAS, LLC • PROGRESS ENERGY, INC. • DUKE ENERGY PROGRESS, LLC •  DUKE ENERGY FLORIDA, LLC • DUKE ENERGY OHIO, INC. • DUKE ENERGY INDIANA, LLC • PIEDMONT NATURAL GAS COMPANY, INC.Combined Notes to Consolidated Financial Statements – (Continued)In general, when the Duke Energy Registrants retire regulated property, 

plant and equipment, the original cost plus the cost of retirement, less salvage 
value and any depreciation already recognized, is charged to accumulated 
depreciation. However, when it becomes probable the asset will be retired 
substantially in advance of its original expected useful life or is abandoned, 
the cost of the asset and the corresponding accumulated depreciation is 
recognized as a separate asset. If the asset is still in operation, the net amount 
is classified as Generation facilities to be retired, net on the Consolidated 
Balance Sheets. If the asset is no longer operating, the net amount is classified 
in Regulatory assets on the Consolidated Balance Sheets if deemed recoverable 
(see discussion of long-lived asset impairments above). The carrying value of 
the asset is based on historical cost if the Duke Energy Registrants are allowed 
to recover the remaining net book value and a return equal to at least the 
incremental borrowing rate. If not, an impairment is recognized to the extent 
the net book value of the asset exceeds the present value of future revenues 
discounted at the incremental borrowing rate.

When the Duke Energy Registrants sell entire regulated operating units, 

or retire or sell nonregulated properties, the original cost and accumulated 
depreciation and amortization balances are removed from Property, Plant and 
Equipment on the Consolidated Balance Sheets. Any gain or loss is recorded 
in earnings, unless otherwise required by the applicable regulatory body. See 
Note 11 for additional information.

Nuclear Fuel

Nuclear fuel is classified as Property, Plant and Equipment on the 

Consolidated Balance Sheets.

Nuclear fuel in the front-end fuel processing phase is considered work 
in progress and not amortized until placed in service. Amortization of nuclear 
fuel is included within Fuel used in electric generation and purchased power on 
the Consolidated Statements of Operations. Amortization is recorded using the 
units-of-production method.

Allowance for Funds Used During Construction and Interest Capitalized

For regulated operations, the debt and equity costs of financing the 
construction of property, plant and equipment are reflected as AFUDC and 
capitalized as a component of the cost of property, plant and equipment. AFUDC 
equity is reported on the Consolidated Statements of Operations as non-cash 
income in Other income and expenses, net. AFUDC debt is reported as a 
non-cash offset to Interest Expense. After construction is completed, the Duke 
Energy Registrants are permitted to recover these costs through their inclusion 
in rate base and the corresponding subsequent depreciation or amortization of 
those regulated assets.

AFUDC equity, a permanent difference for income taxes, reduces the ETR 

when capitalized and increases the ETR when depreciated or amortized. See 
Note 24 for additional information.

For nonregulated operations, interest is capitalized during the 

construction phase with an offsetting non-cash credit to Interest Expense on the 
Consolidated Statements of Operations.

Asset Retirement Obligations

AROs are recognized for legal obligations associated with the retirement 

of property, plant and equipment. Substantially all AROs are related to regulated 
operations. When recording an ARO, the present value of the projected liability 
is recognized in the period in which it is incurred, if a reasonable estimate of 
fair value can be made. The liability is accreted over time. For operating plants, 
the present value of the liability is added to the cost of the associated asset and 

depreciated over the remaining life of the asset. For retired plants, the present 
value of the liability is recorded as a regulatory asset unless determined not to 
be probable of recovery.

The present value of the initial obligation and subsequent updates are 
based on discounted cash flows, which include estimates regarding timing of 
future cash flows, selection of discount rates and cost escalation rates, among 
other factors. These estimates are subject to change. Depreciation expense is 
adjusted prospectively for any changes to the carrying amount of the associated 
asset. The Duke Energy Registrants receive amounts to fund the cost of the 
ARO for regulated operations through a combination of regulated revenues and 
earnings on the NDTF. As a result, amounts recovered in regulated revenues, 
earnings on the NDTF, accretion expense and depreciation of the associated 
asset are netted and deferred as a regulatory asset or liability.

Obligations for nuclear decommissioning are based on site-specific 

cost studies. Duke Energy Carolinas and Duke Energy Progress assume 
prompt dismantlement of the nuclear facilities after operations are ceased. 
In 2019, Duke Energy Florida entered into an agreement for the accelerated 
decommissioning of Crystal River Unit 3. See Note 4 for more information. Duke 
Energy Carolinas, Duke Energy Progress and Duke Energy Florida also assume 
that spent fuel will be stored on-site until such time that it can be transferred to 
a yet to be built DOE facility.

Obligations for closure of ash basins are based upon discounted cash 

flows of estimated costs for site-specific plans, if known, or probability 
weightings of the potential closure methods if the closure plans are under 
development and multiple closure options are being considered and evaluated 
on a site-by-site basis. See Note 10 for additional information.

Revenue Recognition

Duke Energy recognizes revenue as customers obtain control of promised 

goods and services in an amount that reflects consideration expected in 
exchange for those goods or services. Generally, the delivery of electricity 
and natural gas results in the transfer of control to customers at the time the 
commodity is delivered and the amount of revenue recognized is equal to the 
amount billed to each customer, including estimated volumes delivered when 
billings have not yet occurred. See Note 19 for further information.

Derivatives and Hedging

Derivative and non-derivative instruments may be used in connection 
with commodity price and interest rate activities, including swaps, futures, 
forwards and options. All derivative instruments, except those that qualify for 
the NPNS exception, are recorded on the Consolidated Balance Sheets at fair 
value. Qualifying derivative instruments may be designated as either cash 
flow hedges or fair value hedges. Other derivative instruments (undesignated 
contracts) either have not been designated or do not qualify as hedges. The 
effective portion of the change in the fair value of cash flow hedges is recorded 
in AOCI. The effective portion of the change in the fair value of a fair value hedge 
is offset in net income by changes in the hedged item. For activity subject to 
regulatory accounting, gains and losses on derivative contracts are reflected as 
regulatory assets or liabilities and not as other comprehensive income or current 
period income. As a result, changes in fair value of these derivatives have no 
immediate earnings impact.

Formal documentation, including transaction type and risk management 
strategy, is maintained for all contracts accounted for as a hedge. At inception 
and at least every three months thereafter, the hedge contract is assessed to 
see if it is highly effective in offsetting changes in cash flows or fair values of 
hedged items.

See Note 15 for further information.

Pension and Other Post-Retirement Benefit Plans

Duke Energy has captive insurance subsidiaries that provide coverage, 

Duke Energy maintains qualified, non-qualified and other post-retirement 

on an indemnity basis, to the Subsidiary Registrants as well as certain 
third parties, on a limited basis, for financial losses, primarily related to 
property, workers’ compensation and general liability. Liabilities include 
provisions for estimated losses incurred but not reported (IBNR), as well as 
estimated provisions for known claims. IBNR reserve estimates are primarily 
based upon historical loss experience, industry data and other actuarial 
assumptions. Reserve estimates are adjusted in future periods as actual losses 
differ from experience.

Duke Energy, through its captive insurance entities, also has reinsurance 

coverage with third parties for certain losses above a per occurrence and/or 
aggregate retention. Receivables for reinsurance coverage are recognized when 
realization is deemed probable.

Unamortized Debt Premium, Discount and Expense

Premiums, discounts and expenses incurred with the issuance of 
outstanding long-term debt are amortized over the term of the debt issue. The 
gain or loss on extinguishment associated with refinancing higher-cost debt 
obligations in the regulated operations is amortized over the remaining life of 
the original instrument. Amortization expense is recorded as Interest Expense 
in the Consolidated Statements of Operations and is reflected as Depreciation, 
amortization and accretion within Net cash provided by operating activities on 
the Consolidated Statements of Cash Flows.

Premiums, discounts and expenses are presented as an adjustment to 
the carrying value of the debt amount and included in Long-Term Debt on the 
Consolidated Balance Sheets presented.

Preferred Stock

Preferred stock is reviewed to determine the appropriate balance sheet 
classification and embedded features, such as call options, are evaluated to 
determine if they should be bifurcated and accounted for separately. Costs 
directly related to the issuance of preferred stock is recorded as a reduction of 
the proceeds received. The liability for the dividend is recognized when declared. 
The accumulated dividends on the cumulative preferred stock is recognized to 
net income available to Duke Energy Corporation in the EPS calculation. See 
Note 20 for further information.

Loss Contingencies and Environmental Liabilities

Contingent losses are recorded when it is probable a loss has occurred 

and can be reasonably estimated. When a range of the probable loss exists and 
no amount within the range is a better estimate than any other amount, the 
minimum amount in the range is recorded. Unless otherwise required by GAAP, 
legal fees are expensed as incurred.

Environmental liabilities are recorded on an undiscounted basis when 
environmental remediation or other liabilities become probable and can be 
reasonably estimated. Environmental expenditures related to past operations 
that do not generate current or future revenues are expensed. Environmental 
expenditures related to operations that generate current or future revenues are 
expensed or capitalized, as appropriate. Certain environmental expenditures 
receive regulatory accounting treatment and are recorded as regulatory assets.

See Notes 4 and 5 for further information.

benefit plans. Eligible employees of the Subsidiary Registrants participate in 
the respective qualified, non-qualified and other post-retirement benefit plans 
and the Subsidiary Registrants are allocated their proportionate share of benefit 
costs. See Note 23 for further information, including significant accounting 
policies associated with these plans.

Severance and Special Termination Benefits

Duke Energy has severance plans under which in general, the longer a 
terminated employee worked prior to termination the greater the amount of 
severance benefits. A liability for involuntary severance is recorded once an 
involuntary severance plan is committed to by management if involuntary 
severances are probable and can be reasonably estimated. For involuntary 
severance benefits incremental to its ongoing severance plan benefits, the fair 
value of the obligation is expensed at the communication date if there are no 
future service requirements or over the required future service period. Duke 
Energy also offers special termination benefits under voluntary severance 
programs. Special termination benefits are recorded immediately upon employee 
acceptance absent a significant retention period. Otherwise, the cost is recorded 
over the remaining service period. Employee acceptance of voluntary severance 
benefits is determined by management based on the facts and circumstances of 
the benefits being offered. See Note 21 for further information.

Guarantees

If necessary, liabilities are recognized at the time of issuance or material 

modification of a guarantee for the estimated fair value of the obligation it 
assumes. Fair value is estimated using a probability-weighted approach. The 
obligation is reduced over the term of the guarantee or related contract in a 
systematic and rational method as risk is reduced. Any additional contingent 
loss for guarantee contracts subsequent to the initial recognition of a liability 
is accounted for and recognized at the time a loss is probable and can be 
reasonably estimated. See Note 8 for further information.

Stock-Based Compensation

Stock-based compensation represents costs related to stock-based 

awards granted to employees and Board of Directors members. Duke Energy 
recognizes stock-based compensation based upon the estimated fair value of 
awards, net of estimated forfeitures at the date of issuance. The recognition 
period for these costs begins at either the applicable service inception date or 
grant date and continues throughout the requisite service period. Compensation 
cost is recognized as expense or capitalized as a component of property, plant 
and equipment. See Note 22 for further information.

Income Taxes

Duke Energy and its subsidiaries file a consolidated federal income 
tax return and other state and foreign jurisdictional returns. The Subsidiary 
Registrants are parties to a tax-sharing agreement with Duke Energy. Income 
taxes recorded represent amounts the Subsidiary Registrants would incur as 
separate C-Corporations. Deferred income taxes have been provided for temporary 
differences between GAAP and tax bases of assets and liabilities because the 
differences create taxable or tax-deductible amounts for future periods. ITCs 
associated with regulated operations are deferred and amortized as a reduction of 
income tax expense over the estimated useful lives of the related properties.

PART IIDUKE ENERGY CORPORATION • DUKE ENERGY CAROLINAS, LLC • PROGRESS ENERGY, INC. • DUKE ENERGY PROGRESS, LLC •  DUKE ENERGY FLORIDA, LLC • DUKE ENERGY OHIO, INC. • DUKE ENERGY INDIANA, LLC • PIEDMONT NATURAL GAS COMPANY, INC.Combined Notes to Consolidated Financial Statements – (Continued)Accumulated deferred income taxes are valued using the enacted tax rate 

expected to apply to taxable income in the periods in which the deferred tax 
asset or liability is expected to be settled or realized. In the event of a change in 
tax rates, deferred tax assets and liabilities are remeasured as of the enactment 
date of the new rate. To the extent that the change in the value of the deferred 
tax represents an obligation to customers, the impact of the remeasurement is 
deferred to a regulatory liability. Remaining impacts are recorded in income from 
continuing operations. If Duke Energy’s estimate of the tax effect of reversing 
temporary differences is not reflective of actual outcomes, is modified to reflect 
new developments or interpretations of the tax law, revised to incorporate 
new accounting principles, or changes in the expected timing or manner of the 
reversal then Duke Energy’s results of operations could be impacted.

Tax-related interest and penalties are recorded in Interest Expense and 
Other Income and Expenses, net in the Consolidated Statements of Operations.

See Note 24 for further information.

Accounting for Renewable Energy Tax Credits

When Duke Energy receives ITCs on wind or solar facilities, it reduces 

the basis of the property recorded on the Consolidated Balance Sheets by the 
amount of the ITC and, therefore, the ITC benefit is ultimately recognized in the 
statement of operations through reduced depreciation expense. Additionally, 
certain tax credits and government grants result in an initial tax depreciable 
base in excess of the book carrying value by an amount equal to one half of the 
ITC. Deferred tax benefits are recorded as a reduction to income tax expense in 
the period that the basis difference is created.

Duke Energy receives PTCs on wind facilities that are recognized as 

electricity is produced.

Excise Taxes

Certain excise taxes levied by state or local governments are required to 
be paid even if not collected from the customer. These taxes are recognized on 
a gross basis. Taxes for which Duke operates merely as a collection agent for 
the state and local government are accounted for on a net basis. Excise taxes 
accounted for on a gross basis within both Operating Revenues and Property 
and other taxes in the Consolidated Statements of Operations were as follows.

Dividend Restrictions and Unappropriated Retained Earnings

Duke Energy does not have any legal, regulatory or other restrictions on 

paying common stock dividends to shareholders. However, as further described 
in Note 4, Duke Energy Carolinas, Duke Energy Progress, Duke Energy Ohio, Duke 
Energy Indiana and Piedmont have restrictions on paying dividends or otherwise 
advancing funds to Duke Energy due to conditions established by regulators 
in conjunction with merger transaction approvals. At December 31, 2019, and 
2018, an insignificant amount of Duke Energy’s consolidated Retained earnings 
balance represents undistributed earnings of equity method investments.

NEW ACCOUNTING STANDARDS

Except as noted below, the new accounting standards adopted for 2019, 

2018 and 2017 had no material impact on the presentation or results of 
operations, cash flows or financial position of the Duke Energy Registrants.

Leases. In February 2016, the FASB issued revised accounting guidance 
for leases. The core principle of this guidance is that a lessee should recognize 
the assets and liabilities that arise from leases on the balance sheet. This 
resulted in a material impact on the presentation for the statement of financial 
position of the Duke Energy Registrants for the period ended December 31, 
2019, and an immaterial impact to the Duke Energy Registrants’ results of 
operations and cash flows for the year ended December 31, 2019.

Duke Energy elected the modified retrospective method of adoption 
effective January 1, 2019. Under the modified retrospective method of adoption, 
prior year reported results are not restated. For adoption, Duke Energy elected to 
apply the following practical expedients:

Practical Expedient

Description

Package of transition practical expedients (for leases commenced prior to adoption date 
and must be adopted as a package)

Short-term lease expedient (elect by class of underlying asset)

Lease and non-lease components (elect by class of underlying asset)

Hindsight expedient (when determining lease term)
Existing and expired land easements not previously accounted for as leases

Comparative reporting requirements for initial adoption

Lessor expedient (elect by class of underlying asset)

Do not need to 1) reassess whether any expired or existing contracts are/or contain 
leases, 2) reassess the lease classification for any expired or existing leases and 
3) reassess initial direct costs for any existing leases.
Elect as an accounting policy to not apply the recognition requirements to short-term 
leases by asset class.
Elect as an accounting policy to not separate non-lease components from lease 
components and instead account for each lease and associated non-lease component as 
a single lease component by asset class.
Elect to use hindsight to determine the lease term.
Elect to not evaluate existing or expired easements under the new guidance and carry 
forward current accounting treatment.
Elect to apply transition requirements at adoption date, recognize cumulative effect 
adjustment to retained earnings in period of adoption and not apply the new requirements 
to comparative periods, including disclosures.
Elect as an accounting policy to aggregate non-lease components with the related lease 
component when specified conditions are met by asset class. Account for the combined 
component based on its predominant characteristic (revenue or operating lease).

standard and monitored industry implementation issues. Under agreements 
considered leases, where Duke Energy is the lessee, for the use of certain 
aircraft, space on communication towers, industrial equipment, fleet vehicles, 
fuel transportation (barges and railcars), land, office space and PPAs are now 
recognized on the balance sheet. The Duke Energy Registrants did not have 
a material change to the financial statements from the adoption of the new 
standard for contracts where it is the lessor. See Note 6 for further information.
The following new accounting standard has been issued but not yet 

adopted by the Duke Energy Registrants as of December 31, 2019.

Credit Losses. In June 2016, the FASB issued new accounting guidance 

for credit losses. This guidance establishes a new impairment model 
applicable to certain financial assets, including trade and other receivables, 

net investments in leases, and debt securities classified as held-for-sale 
investments. The model also applies to financial guarantees.

For Duke Energy, the guidance is effective for interim and annual periods 

beginning January 1, 2020. This guidance will be applied using a modified 
retrospective approach. Under the modified retrospective approach of adoption, 
prior year reported results are not restated and a cumulative-effect adjustment 
is recorded to retained earnings at January 1, 2020.

Upon adoption, Duke Energy will recognize an allowance for credit losses 

based on management’s estimate of losses expected to be incurred over the 
lives of certain assets or guarantees. Duke Energy expects the impacts of this 
standard to be driven by the reserve for credit losses on financial guarantees, 
trade and other receivables, and insurance receivables. Duke Energy does not 
intend to adopt any practical expedients.

Duke Energy currently expects to record a reserve for credit losses as shown in approximate amounts in the table below:

In addition to the reserve for credit losses, Duke Energy expects additional disclosures on management’s evaluation of credit risks inherent in financial assets 

and how management monitors credit quality, changes in expected credit losses, and the appropriateness of the allowance for credit losses on a forward-looking 
basis. Duke Energy also expects additional disclosures around credit losses for new investments in leases, loan commitments, and other financial instruments.

2.  ACQUISITIONS AND DISPOSITIONS

ACQUISITIONS

The Duke Energy Registrants consolidate assets and liabilities from 
acquisitions as of the purchase date and include earnings from acquisitions in 
consolidated earnings after the purchase date.

2016 Acquisition of Piedmont Natural Gas

On October 3, 2016, Duke Energy acquired all outstanding common 

stock of Piedmont for a total cash purchase price of $5 billion and assumed 
Piedmont’s existing long-term debt, which had a fair value of approximately 
$2 billion at the time of the acquisition. The acquisition provides a foundation 
for Duke Energy to establish a broader, long-term strategic natural gas 
infrastructure platform to complement its existing natural gas pipeline 
investments and regulated natural gas business in the Midwest. In connection 
with the closing of the acquisition, Piedmont became a wholly owned subsidiary 
of Duke Energy.

Accounting Charges Related to the Acquisition

Duke Energy incurred pretax transaction and integration costs 
associated with the acquisition of $84 million and $103 million for the years 
ended December 31, 2018, and 2017, respectively. Amounts recorded on 
the Consolidated Statements of Operations in 2018 and 2017 were primarily 
system integration costs of $78 million and $71 million, respectively, related to 

combining the various operational and financial systems of Duke Energy and 
Piedmont, including a one-time software impairment resulting from planned 
accounting system and process integration in 2017. A $7 million charge was 
recorded within Impairment Charges, with the remaining $64 million recorded 
within Operation, maintenance and other in 2017.

The majority of transition and integration activities were completed by the 

end of 2018.

DISPOSITIONS

On April 24, 2019, Duke Energy executed an agreement to sell a minority 

interest in a portion of certain renewable assets within the Commercial 
Renewables segment. The sale closed on September 6, 2019, and resulted in 
pretax proceeds to Duke Energy of $415 million. The portion of Duke Energy’s 
commercial renewables energy portfolio sold includes 49% of 37 operating 
wind, solar and battery storage assets and 33% of 11 operating solar assets 
across the U.S. Duke Energy retained control of these assets, and, therefore, 
no gain or loss was recognized on the Consolidated Statements of Operations. 
The difference between the consideration received and the carrying value of the 
noncontrolling interest claim on net assets is $466 million, net of a tax benefit of 
$8 million, and was recorded in equity.

BUSINESS SEGMENTS

Reportable segments are determined based on information used by 
the chief operating decision-maker in deciding how to allocate resources and 
evaluate the performance of the business. Duke Energy evaluates segment 
performance based on segment income. Segment income is defined as income 
from continuing operations net of income attributable to noncontrolling interests. 
Segment income, as discussed below, includes intercompany revenues and 
expenses that are eliminated on the Consolidated Financial Statements. Certain 
governance costs are allocated to each segment. In addition, direct interest 
expense and income taxes are included in segment income.

Products and services are sold between affiliate companies and 

reportable segments of Duke Energy at cost. Segment assets as presented in the 
tables that follow exclude all intercompany assets.

Duke Energy

Duke Energy’s segment structure includes the following segments: Electric 

Utilities and Infrastructure, Gas Utilities and Infrastructure and Commercial 
Renewables.

The Electric Utilities and Infrastructure segment includes Duke 
Energy’s regulated electric utilities in the Carolinas, Florida and the Midwest. 

The regulated electric utilities conduct operations through the Subsidiary 
Registrants that are substantially all regulated and, accordingly, qualify for 
regulatory accounting treatment. Electric Utilities and Infrastructure also 
includes Duke Energy’s electric transmission infrastructure investments.

The Gas Utilities and Infrastructure segment includes Piedmont, Duke 
Energy’s natural gas local distribution companies in Ohio and Kentucky, and 
Duke Energy’s natural gas storage and midstream pipeline investments. Gas 
Utilities and Infrastructure’s operations are substantially all regulated and, 
accordingly, qualify for regulatory accounting treatment.

The Commercial Renewables segment is primarily comprised of 
nonregulated utility-scale wind and solar generation assets located throughout 
the U.S. On April 24, 2019, Duke Energy executed an agreement to sell a 
minority interest in a portion of certain renewable assets. See Note 2 for 
additional information on the minority interest sale.

The remainder of Duke Energy’s operations is presented as Other, which 

is primarily comprised of interest expense on holding company debt, unallocated 
corporate costs and Duke Energy’s wholly owned captive insurance company, 
Bison. Other also includes Duke Energy’s interest in NMC. See Note 13 for 
additional information on the investment in NMC.

Duke Energy Ohio has two reportable segments, Electric Utilities and Infrastructure and Gas Utilities and Infrastructure.
Electric Utilities and Infrastructure transmits and distributes electricity in portions of Ohio and generates, distributes and sells electricity in portions of Northern 

Kentucky. Gas Utilities and Infrastructure transports and sells natural gas in portions of Ohio and Northern Kentucky. Both reportable segments conduct operations 
primarily through Duke Energy Ohio and its wholly owned subsidiary, Duke Energy Kentucky.

The remainder of Duke Energy Ohio’s operations is presented as Other. In December 2018, the PUCO approved an order which allows the recovery or credit 

of revenues and expenses related to Duke Energy Ohio’s contractual arrangement to buy power from OVEC power plants. Due to the change in regulatory treatment 
of these amounts, OVEC revenues and expenses are now reflected in the Electric Utilities and Infrastructure segment. Previously, OVEC revenues and expense 
were included in Other. These amounts are deemed immaterial for Duke Energy Ohio. Therefore, no prior period amounts were restated. See Note 4 for additional 
information on the PUCO order.

above and below follow. See tables below for recovery and amortization periods 
at the separate registrants.

AROs – coal ash. Represents deferred depreciation and accretion related 
to the legal obligation to close ash basins. The costs are deferred until recovery 
treatment has been determined. See Notes 1 and 10 for additional information.
AROs – nuclear and other. Represents regulatory assets or liabilities, 

including deferred depreciation and accretion, related to legal obligations 
associated with the future retirement of property, plant and equipment, 
excluding amounts related to coal ash. The AROs relate primarily to 
decommissioning nuclear power facilities. The amounts also include certain 
deferred gains and losses on NDTF investments. See Notes 1 and 10 for 
additional information.

Accrued pension and OPEB. Accrued pension and OPEB represent 
regulatory assets and liabilities related to each of the Duke Energy Registrants’ 
respective shares of unrecognized actuarial gains and losses and unrecognized 
prior service cost and credit attributable to Duke Energy’s pension plans and 
OPEB plans. The regulatory asset or liability is amortized with the recognition 
of actuarial gains and losses and prior service cost and credit to net periodic 
benefit costs for pension and OPEB plans. The accrued pension and OPEB 
regulatory assets are expected to be recovered primarily over the average 
remaining service periods or life expectancies of employees covered by the 
benefit plans. See Note 23 for additional detail.

Storm cost deferrals. Represents deferred incremental costs incurred 

related to major weather-related events.

Nuclear asset securitized balance, net. Represents the balance 

associated with Crystal River Unit 3 retirement approved for recovery by the 
FPSC on September 15, 2015, and the upfront financing costs securitized in 
2016 with issuance of the associated bonds. The regulatory asset balance is net 
of the AFUDC equity portion.

Debt fair value adjustment. Purchase accounting adjustments recorded 

to state the carrying value of Progress Energy and Piedmont at fair value in 
connection with the 2012 and 2016 mergers, respectively. Amount is amortized 
over the life of the related debt.

Deferred fuel and purchased power. Represents certain energy-
related costs that are recoverable or refundable as approved by the applicable 
regulatory body.

Deferred asset – Lee and Harris COLA. Represents deferred costs 

incurred for the canceled Lee and Harris nuclear projects.

Hedge costs and other deferrals. Amounts relate to unrealized gains 

and losses on derivatives recorded as a regulatory asset or liability, respectively, 
until the contracts are settled.

DSM/EE. Deferred costs related to various DSM and EE programs 

recoverable through various mechanisms.

AMI. Represents deferred costs related to the installation of AMI meters 
and remaining net book value of non-AMI meters to be replaced at Duke Energy 
Carolinas, net book value of existing meters at Duke Energy Florida, Duke Energy 
Progress and Duke Energy Ohio and expected future recovery of net book value 
of electromechanical meters that have been replaced with AMI meters at Duke 
Energy Indiana.

Retired generation facilities. Represents amounts to be recovered for 

facilities that have been retired and are probable of recovery.

Post-in-service carrying costs (PISCC) and deferred operating 
expenses. Represents deferred depreciation and operating expenses as well as 

carrying costs on the portion of capital expenditures placed in service but not yet 
reflected in retail rates as plant in service.

Vacation accrual. Represents vacation entitlement, which is generally 

recovered in the following year.

Derivatives – natural gas supply contracts. Represents costs for 
certain long-dated, fixed quantity forward gas supply contracts, which are 
recoverable through PGA clauses.

Nuclear deferral. Includes amounts related to levelizing nuclear plant 
outage costs, which allows for the recognition of nuclear outage expenses over 
the refueling cycle rather than when the outage occurs, resulting in the deferral 
of operations and maintenance costs associated with refueling.

MGP. Represents remediation costs incurred at former MGP sites and 
the deferral of costs to be incurred at Duke Energy Ohio’s East End and West 
End sites.

Deferred pipeline integrity costs. Represents pipeline integrity 
management costs in compliance with federal regulations recovered through a 
rider mechanism.

NCEMPA deferrals. Represents retail allocated cost deferrals and returns 

associated with the additional ownership interest in assets acquired from 
NCEMPA in 2015.

East Bend deferrals. Represents both deferred operating expenses and 

deferred depreciation as well as carrying costs on the portion of East Bend 
that was acquired from Dayton Power and Light and that had been previously 
operated as a jointly owned facility.

Transmission expansion obligation. Represents transmission 
expansion obligations related to Duke Energy Ohio’s withdrawal from MISO.

Amounts due from customers. Relates primarily to margin decoupling 

and IMR recovery mechanisms.

Grid modernization. Amounts represent deferred depreciation 
and operating expenses as well as carrying costs on the portion of capital 
expenditures placed in service but not yet reflected in retail rates as plant 
in service.

Net regulatory liability related to income taxes. Amounts for all 
registrants include regulatory liabilities related primarily to impacts from the Tax 
Act. See Note 24 for additional information. Amounts have no immediate impact 
on rate base as regulatory assets are offset by deferred tax liabilities.

Costs of removal. Represents funds received from customers to cover 
the future removal of property, plant and equipment from retired or abandoned 
sites as property is retired. Also includes certain deferred gains on NDTF 
investments.

Amounts to be refunded to customers. Represents required rate 

reductions to retail customers by the applicable regulatory body.

RESTRICTIONS ON THE ABILITY OF CERTAIN SUBSIDIARIES TO MAKE 
DIVIDENDS, ADVANCES AND LOANS TO DUKE ENERGY

PUCO, KPSC and IURC imposed conditions on the ability of Duke Energy 
Carolinas, Duke Energy Progress, Duke Energy Ohio, Duke Energy Kentucky, 
Duke Energy Indiana and Piedmont to transfer funds to Duke Energy through 
loans or advances, as well as restricted amounts available to pay dividends to

on their ability to dividend, loan or advance funds to Duke Energy due to specific 
legal or regulatory restrictions, including, but not limited to, minimum working 
capital and tangible net worth requirements.

The restrictions discussed below were not a material amount of Duke 

Energy’s and Progress Energy’s net assets at December 31, 2019.

Duke Energy Carolinas

Duke Energy Carolinas must limit cumulative distributions subsequent to 
mergers to (i) the amount of retained earnings on the day prior to the closing of 
the mergers, plus (ii) any future earnings recorded.

Duke Energy Progress

Duke Energy Progress must limit cumulative distributions subsequent to 
the mergers between Duke Energy and Progress Energy and Duke Energy and 
Piedmont to (i) the amount of retained earnings on the day prior to the closing of 
the respective mergers, plus (ii) any future earnings recorded.

Duke Energy Ohio

Duke Energy Ohio will not declare and pay dividends out of capital or 
unearned surplus without the prior authorization of the PUCO. Duke Energy Ohio 
received FERC and PUCO approval to pay dividends from its equity accounts 
that are reflective of the amount that it would have in its retained earnings 
account had push-down accounting for the Cinergy merger not been applied to 
Duke Energy Ohio’s balance sheet. The conditions include a commitment from 
Duke Energy Ohio that equity, adjusted to remove the impacts of push-down 
accounting, will not fall below 30% of total capital.

Duke Energy Kentucky is required to pay dividends solely out of retained 

earnings and to maintain a minimum of 35% equity in its capital structure.

Duke Energy Indiana

Duke Energy Indiana must limit cumulative distributions subsequent 

to the merger between Duke Energy and Cinergy to (i) the amount of retained 
earnings on the day prior to the closing of the merger, plus (ii) any future 
earnings recorded. In addition, Duke Energy Indiana will not declare and pay 
dividends out of capital or unearned surplus without prior authorization of 
the IURC.

Piedmont

Piedmont must limit cumulative distributions subsequent to the 

acquisition of Piedmont by Duke Energy to (i) the amount of retained earnings on 
the day prior to the closing of the merger, plus (ii) any future earnings recorded.

The NCUC, PSCSC, FPSC, IURC, PUCO, TPUC and KPSC approve rates for 
retail electric and natural gas services within their states. The FERC approves 
rates for electric sales to wholesale customers served under cost-based 
rates (excluding Ohio and Indiana), as well as sales of transmission service. 
The FERC also regulates certification and siting of new interstate natural gas 
pipeline projects.

Duke Energy Carolinas and Duke Energy Progress

Hurricane Florence, Hurricane Michael and Winter Storm Diego 
Deferral Filings

On December 21, 2018, Duke Energy Carolinas and Duke Energy Progress 

filed with the NCUC petitions for approval to defer the incremental costs 
incurred in connection with the response to Hurricane Florence, Hurricane 
Michael and Winter Storm Diego to a regulatory asset for recovery in the next 
base rate case. The NCUC issued an order requesting comments on the deferral 
positions. On March 5, 2019, the North Carolina Public Staff (Public Staff) filed 
comments. On April 2, 2019, Duke Energy Carolinas and Duke Energy Progress 
filed reply comments, which included revised estimates of approximately 
$553 million in incremental operation and maintenance expenses ($171 million 
and $382 million for Duke Energy Carolinas and Duke Energy Progress, 
respectively) and approximately $96 million in capital costs ($20 million and 
$76 million for Duke Energy Carolinas and Duke Energy Progress, respectively). 
On September 30, 2019, Duke Energy Carolinas requested that the NCUC 
consolidate its pending deferral request with its general rate case filed on that 
date. On October 30, 2019, Duke Energy Progress requested that the NCUC 
consolidate its pending deferral request with its general rate case filed on 
that date. Duke Energy Carolinas and Duke Energy Progress cannot predict 
the outcome of these matters. Duke Energy Progress filed a deferral request 
for these storms with the PSCSC on January 11, 2019, which also included 
a request for the continuation of prior deferrals requested for ice storms and 
Hurricane Matthew, and on January 30, 2019, the PSCSC issued a directive 
approving the deferral request, followed by an order issued on February 21, 
2019. On March 15, 2019, Duke Energy Progress filed a request with FERC 
requesting permission to defer transmission-related storm costs that would be 
charged to wholesale transmission customers through Duke Energy Progress’ 
Open Access Transmission Tariff (OATT) and to recover those costs from 
wholesale transmission customers over a three-year recovery period. FERC 
accepted the filing on May 14, 2019, which allows Duke Energy Progress to 
proceed with the proposed cost deferral and recovery.

2019 North Carolina Rate Case

On August 25, 2017, Duke Energy Carolinas filed an application with the 

NCUC for a rate increase for retail customers of approximately $647 million, 
which represented an approximate 13.6% increase in annual base revenues. 
The request for rate increase was driven by capital investments subsequent 
to the previous base rate case, including the W.S. Lee CC, grid improvement 
projects, AMI, investments in customer service technologies, costs of complying 
with CCR regulations and the Coal Ash Act and recovery of costs related to 
licensing and development of the William States Lee III Nuclear Station.

On February 28, 2018, Duke Energy Carolinas and the Public Staff filed 
an Agreement and Stipulation of Partial Settlement resolving certain portions 
of the proceeding. Terms of the settlement included a return on equity of 
9.9% and a capital structure of 52% equity and 48% debt. As a result of the 
settlement, Duke Energy Carolinas recorded a pretax charge of approximately 
$4 million in the first quarter of 2018 to Operation, maintenance and other on 
the Consolidated Statements of Operations.

On June 22, 2018, the NCUC issued an order approving the Stipulation of 

Partial Settlement and requiring a revenue reduction.

As a result of the June 22, 2018, order, Duke Energy Carolinas recorded 

a pretax charge of approximately $150 million to Impairment charges and 
Operation, maintenance and other on the Consolidated Statements of 
Operations. The charge was primarily related to the denial of a return on the Lee 
Nuclear Project and the assessment of a $70 million management penalty by 
reducing the annual recovery of deferred coal ash costs by $14 million per year 
over a five-year recovery period. On July 27, 2018, NCUC approved Duke Energy 
Carolinas’ compliance filing. As a result, revised customer rates were effective 
on August 1, 2018.

On July 20, 2018, the North Carolina Attorney General filed a Notice of 
Appeal to the North Carolina Supreme Court from the June 22, 2018, Order 
Accepting Stipulation, Deciding Contested Issues and Requiring Revenue 
Reduction issued by the NCUC. The Attorney General contends the commission’s 
order should be reversed and remanded, as it is in excess of the commission’s 
statutory authority; affected by errors of law; unsupported by competent, 
material and substantial evidence in view of the entire record as submitted; 
and arbitrary or capricious. The Sierra Club, North Carolina Sustainable 
Energy Association, North Carolina Justice Center, North Carolina Housing 
Coalition, Natural Resource Defense Council and Southern Alliance for Clean 
Energy also filed Notices of Appeal to the North Carolina Supreme Court. On 
August 8, 2018, the Public Staff filed a Notice of Cross Appeal to the North 
Carolina Supreme Court, which contends the commission’s June 22, 2018, 
order should be reversed and remanded, as it is affected by errors of law, and 
is unsupported by substantial evidence with regard to the commission’s failure 
to consider substantial evidence of coal ash related environmental violations. 
On November 29, 2018, the North Carolina Attorney General’s Office filed a 
motion with the North Carolina Supreme Court requesting the court consolidate 
the Duke Energy Carolinas and Duke Energy Progress appeals and enter an 
order adopting the parties’ proposed briefing schedule as set out in the filing. 
On November 29, 2018, the North Carolina Supreme Court adopted a schedule 
for briefing set forth in the motion to consolidate the Duke Energy Carolinas and 
Duke Energy Progress appeals. Appellant briefs were filed on April 26, 2019. 
The Appellee response briefs were filed on September 25, 2019. Oral arguments 
before the North Carolina Supreme Court are scheduled for March 11, 2020. 
Duke Energy Carolinas cannot predict the outcome of this matter.

On September 30, 2019, Duke Energy Carolinas filed an application 
with the NCUC for a net rate increase for retail customers of approximately 
$291 million, which represents an approximate 6% increase in annual base 
revenues. The gross rate case revenue increase request is $445 million, which 
is offset by an EDIT rider of $154 million to return to customers North Carolina 
and federal EDIT resulting from recent reductions in corporate tax rates. The 
request for rate increase is driven by major capital investments subsequent to 
the previous base rate case, coal ash pond closure costs, accelerated coal plant 
depreciation and deferred 2018 storm costs. Duke Energy Carolinas requests 
rates be effective no later than August 1, 2020. The NCUC has established a 
procedural schedule with an evidentiary hearing to commence on March 23, 
2020. Duke Energy Carolinas cannot predict the outcome of this matter.

2018 South Carolina Rate Case

On November 8, 2018, Duke Energy Carolinas filed an application with the 

PSCSC for a rate increase for retail customers of approximately $168 million, 
which represents an approximate 10% increase in retail revenues. The request for 
rate increase was driven by capital investments and environmental compliance 
progress made by Duke Energy Carolinas since its previous rate case, including 
the further implementation of Duke Energy Carolinas’ generation modernization 
program, which consists of retiring, replacing and upgrading generation plants, 
investments in customer service technologies and continued investments in 
base work to maintain its transmission and distribution systems. The request 
included net tax benefits resulting from the Tax Act of $66 million to reflect the 
change in ongoing tax expense, primarily from the reduction in the federal income 
tax rate from 35% to 21%. The request also included $46 million to return 
EDIT resulting from the federal tax rate change and deferred revenues since 
January 2018 related to the change and benefits of $17 million from a reduction in 
North Carolina state income taxes allocable to South Carolina (EDIT Rider).
Duke Energy Carolinas also requested approval of its proposed Grid 

Improvement Plan (GIP), adjustments to its Prepaid Advantage Program and 
a variety of accounting orders related to ongoing costs for environmental 
compliance, including recovery over a five-year period of $242 million of 
deferred coal ash related compliance costs, grid investments between rate 
changes, incremental depreciation expense, a result of new depreciation rates 
from the depreciation study approved in the 2017 North Carolina Rate Case 
above, and the balance of development costs associated with the cancellation 
of the Lee Nuclear Project. Finally, Duke Energy Carolinas sought approval to 
establish a reserve and accrual for end-of-life nuclear costs for nuclear fuel 
and materials and supplies. On March 8, 2019, the ORS moved to establish 
a new and separate hearing docket to review and consider the GIP proposed 
by Duke Energy Carolinas. Subsequently, on March 12, 2019, the ORS and 
Duke Energy Carolinas executed a Stipulation resolving the ORS’s motion. The 
Stipulation provided that costs incurred for the GIP after January 1, 2019, would 
be deferred with a return, subject to evaluation in a future rate proceeding. The 
Stipulation was approved by the PSCSC on June 19, 2019. On December 16, 
2019, Duke Energy Carolinas and Duke Energy Progress filed a Joint Petition 
to Establish an Informational Docket for Review and Consideration of Grid 
Improvement Plans through which Duke Energy Carolinas and Duke Energy 
Progress would provide interested stakeholders information on the companies’ 
grid activities. The PSCSC requested parties comment on procedural matters by 
January 31; accordingly, various groups filed comments, none of which opposed 
an informational docket. Duke Energy Carolinas cannot predict the outcome of 
this matter.

2019, which included a return on equity of 9.5% and a capital structure of 
53% equity and 47% debt. The order also included the following material 
components:

• Approval of cancellation of the Lee Nuclear Project, with Duke Energy 

Carolinas maintaining the Combined Operating License;

• Approval of recovery of $125 million (South Carolina retail portion) 
of Lee Nuclear Project development costs (including AFUDC through 
December 2017) over a 12-year period, but denial of a return on the 
deferred balance of costs;

• Approval of recovery of $96 million of coal ash costs over a five-year 

period with a return at Duke Energy Carolinas’ WACC;

• Denial of recovery of $115 million of certain coal ash costs deemed to 
be related to the Coal Ash Act and incremental to the federal CCR rule;

• Approval of a $66 million decrease to base rates to reflect the change 

in ongoing tax expense, primarily the reduction in the federal income tax 
rate from 35% to 21%;

• Approval of a $45 million decrease through the EDIT Rider to return 

EDIT resulting from the federal tax rate change and deferred revenues 
since January 2018 related to the change, to be returned in accordance 
with the Average Rate Assumption Method (ARAM) for protected EDIT, 
over a 20-year period for unprotected EDIT associated with Property, 
Plant and Equipment, over a five-year period for unprotected EDIT not 
associated with Property, Plant and Equipment and over a five-year 
period for the deferred revenues; and

• Approval of a $17 million decrease through the EDIT Rider related to 
reductions in the North Carolina state income tax rate from 6.9% to 
2.5% to be returned over a five-year period.

As a result of the order, revised customer rates were effective June 1, 
2019. On May 31, 2019, Duke Energy Carolinas filed a Petition for Rehearing 
or Reconsideration of that order contending substantial rights of Duke Energy 
Carolinas were prejudiced by unlawful, arbitrary and capricious rulings by 
the commission on certain issues presented in the proceeding. On June 19, 
2019, the PSCSC issued a Directive denying Duke Energy Carolinas’ request 
to rehear or reconsider the commission’s rulings on certain issues presented 
in the proceeding including coal ash remediation and disposal costs, return 
on equity and the recovery of a return on deferred operation and maintenance 
expenses. An order detailing the commission’s decision in the Directive was 
issued on October 18, 2019. Duke Energy Carolinas filed a notice of appeal on 
November 15, 2019, with the South Carolina Supreme Court. On November 20, 
2019, the South Carolina Energy Users Committee filed a Notice of Appeal and 
the ORS filed a Notice of Cross Appeal with the South Carolina Supreme Court. 
On January 8, 2020, Duke Energy Carolinas and the ORS filed a joint motion 
to extend briefing schedule deadlines. Appellant briefs are due on March 2, 
2020, and Appellee response briefs are due on May 15, 2020. On February 12, 
2020, Duke Energy Carolinas and the ORS filed a joint motion to extend briefing 
deadlines by 30 days. Based on legal analysis and the filing of the appeal, Duke 
Energy Carolinas has not recorded an adjustment for its deferred coal ash costs. 
Duke Energy Carolinas cannot predict the outcome of this matter.

FERC Formula Rate Matter

On July 31, 2017, PMPA filed a complaint with FERC alleging that Duke 
Energy Carolinas misapplied the formula rate under the PPA between the parties 
by including in its rates amortization expense associated with regulatory assets 
and recorded in a certain account without FERC approval. On February 15, 
2018, FERC issued an order ruling in favor of PMPA and ordered Duke Energy 
Carolinas to refund to PMPA all amounts improperly collected under the PPA. 
Duke Energy Carolinas has issued to PMPA and similarly situated wholesale 
customers refunds of approximately $25 million. FERC also set the matter for 
settlement and hearing. PMPA and other customers filed a protest to Duke 
Energy Carolinas’ refund report claiming that the refunds are inadequate in 
that (1) Duke Energy Carolinas invoked the limitations periods in the contracts 
to limit the time period for which the refunds were paid and the customers 
disagree that this limitation applies, and (2) Duke Energy Carolinas refunded 
only amounts recovered through a certain account and the customers have 
asserted that the order applies to all regulatory assets. On July 3, 2018, FERC 
issued an order accepting Duke Energy Carolinas’ refund report and ruling that 
these two claims are outside the scope of FERC’s February order. The settlement 
agreements and revised formula rates for all parties to the proceeding were 
filed on December 28, 2018. On April 2, 2019, FERC issued an order approving 
the settlement agreement as filed. Since then, Duke Energy Carolinas has 
implemented the terms of the settlement in rates with all wholesale customers, 
including non-intervening customers. On July 25, 2019, Duke Energy Carolinas 
received FERC approval for the accounting treatment requested for certain 
assets included in the settlement agreements. This is the final approval needed 
from FERC and concludes this proceeding.

Sale of Hydroelectric (Hydro) Plants

In May 2018, Duke Energy Carolinas entered an agreement for the sale of 
five hydro plants with a combined 18.7-MW generation capacity in the Western 
Carolinas region to Northbrook Energy. The completion of the transaction was 
subject to approval from FERC for the four FERC-licensed plants, as well as 
other state regulatory agencies and was contingent upon regulatory approval 
from the NCUC and PSCSC to defer the total estimated loss on the sale of 
approximately $40 million. On July 5, 2018, Duke Energy Carolinas filed with 
the NCUC for approval of the sale of the five hydro plants to Northbrook, to 
transfer the CPCNs for the four North Carolina hydro plants and to establish a 
regulatory asset for the North Carolina retail portion of the difference between 
sales proceeds and net book value. On June 5, 2019, the NCUC issued an 
order approving the transfer of the hydro plants from Duke Energy Carolinas to 
Northbrook, granting deferral accounting and denying the Public Staff’s motion 
for reconsideration.

On August 28, 2018, Duke Energy Carolinas filed with PSCSC an 

Application for Approval of Transfer and Sale of Hydroelectric Generation 
Facilities, Acceptance for Filing of a Power Purchase Agreement and an 
Accounting Order to Establish a Regulatory Asset. On September 10, 2018, the 
ORS provided a letter to the commission stating its position on the application 
and on September 18, 2018, Duke Energy Carolinas requested this matter be 
carried over to allow Duke Energy Carolinas time to discuss certain accounting 
issues with the ORS. At its June 26, 2019, agenda meeting, the PSCSC voted to 
approve the transfer and sale subject to the recommendation of the ORS that 
the issuance of an Accounting Order will not preclude the ORS, the commission 
or any other party from addressing the reasonableness of these costs, any 
return sought and including any carrying costs in the next rate case.

joint Application for Transfer of Licenses with the FERC. On December 27, 
2018, the FERC issued its Order Approving Transfer of Licenses for the four 
FERC-licensed hydro plants. On January 18, 2019, Duke Energy Carolinas and 
Northbrook Carolina Hydro II, LLC requested a six-month extension of time to 
comply with the requirement of the December 27, 2018, order that Northbrook 
submit to FERC certified copies of all instruments of conveyance and signed 
acceptance sheets within 60 days of the date of the order. On February 14, 

2019, FERC issued an order granting extensions until August 26, 2019, to 
comply with the requirements of the December 27, 2018, order.

The closing occurred on August 16, 2019. A regulatory asset was 
established for approximately $32 million, which represents the total deferral 
amount for North Carolina and South Carolina retail. The North Carolina retail 
portion will be amortized pursuant to an order from the NCUC. Duke Energy 
Carolinas will purchase all the capacity and energy generated by these facilities 
at the avoided cost for five years through power purchase agreements.

Hurricane Dorian

On June 1, 2017, Duke Energy Progress filed an application with the 

NCUC for a rate increase for retail customers of approximately $477 million, 
which represented an approximate 14.9% increase in annual base revenues. 
Subsequent to the filing, Duke Energy Progress adjusted the requested amount 
to $420 million, representing an approximate 13% increase. The request for rate 
increase was driven by capital investments subsequent to the previous base 
rate case, costs of complying with CCR regulations and the Coal Ash Act, costs 
relating to storm recovery, investments in customer service technologies and 
recovery of costs associated with renewable purchased power.

On November 22, 2017, Duke Energy Progress and the Public Staff filed 
an Agreement and Stipulation of Partial Settlement resolving certain portions 
of the proceeding. Terms of the settlement included a return on equity of 9.9% 
and a capital structure of 52% equity and 48% debt. On February 23, 2018, the 
NCUC issued an order approving the stipulation.

The order also impacted certain amounts that were similarly recorded on 
Duke Energy Carolinas’ Consolidated Balance Sheets. As a result of the order, 
Duke Energy Progress and Duke Energy Carolinas recorded pretax charges 
of $68 million and $14 million, respectively, in the first quarter of 2018 to 
Impairment charges, Operation, maintenance and other and Interest Expense 
on the Consolidated Statements of Operations. Revised customer rates became 
effective on March 16, 2018.

On May 15, 2018, the Public Staff filed a Notice of Cross Appeal to the 
North Carolina Supreme Court from the NCUC’s February 23, 2018, order. The 
Public Staff contends the NCUC’s order should be reversed and remanded, 
as it is affected by errors of law, and is unsupported by competent, material 
and substantial evidence in view of the entire record as submitted. The 
North Carolina Attorney General and Sierra Club also filed Notices of Appeal 
to the North Carolina Supreme Court from the February 23, 2018, order. On 
November 29, 2018, the North Carolina Attorney General’s Office filed a 
motion with the North Carolina Supreme Court requesting the court consolidate 
the Duke Energy Progress and Duke Energy Carolinas appeals and enter an 
order adopting the parties’ proposed briefing schedule as set out in the filing. 
Appellant briefs were filed on April 26, 2019. The Appellee response briefs were 
filed on September 25, 2019. Oral arguments before the North Carolina Supreme 
Court are scheduled for March 11, 2020. Duke Energy Progress cannot predict 
the outcome of this matter.

2019 North Carolina Rate Case

On October 30, 2019, Duke Energy Progress filed an application with the 

NCUC for a net rate increase for retail customers of approximately $464 million, 
which represents an approximate 12.3% increase in annual base revenues. 
The gross rate case revenue increase request is $586 million, which is offset 
by riders of $122 million, primarily an EDIT rider of $120 million to return to 
customers North Carolina and federal EDIT resulting from recent reductions 
in corporate tax rates. The request for rate increase is driven by major capital 
investments subsequent to the previous base rate case, coal ash pond closure 
costs, accelerated coal plant depreciation and deferred 2018 storm costs. 
Duke Energy Progress seeks to defer and recover incremental Hurricane Dorian 
storm costs in this proceeding and requests rates be effective no later than 
September 1, 2020. The NCUC has established a procedural schedule with an 
evidentiary hearing to commence on May 4, 2020. Duke Energy Progress cannot 
predict the outcome of this matter.

Hurricane Dorian reached the Carolinas in September 2019 as a 
Category 2 hurricane making landfall within Duke Energy Progress’ service 
territory. Approximately 270,000 North Carolina customers and 30,000 South 
Carolina customers were impacted by the slow-moving storm that brought high 
winds, tornadoes and heavy rain. With storm-response mobilization occurring 
in preparation for the storm and the assistance of mutual aid partners, full 
restoration was accomplished within four days for all customers able to receive 
service. Total estimated incremental operation and maintenance expenses 
incurred to repair and restore the system are approximately $205 million with 
an additional $4 million in capital investments made for restoration efforts. 
Approximately $179 million of the operation and maintenance expenses 
are deferred in Regulatory assets within Other Noncurrent Assets on the 
Consolidated Balance Sheets as of December 31, 2019. The balance of 
operation and maintenance expenses are included in Operation, maintenance 
and other on the Consolidated Statements of Operations for the year ended 
December 31, 2019. A request for an accounting order to defer incremental 
storm costs associated with Hurricane Dorian was included in Duke Energy 
Progress’ October 30, 2019, general rate case filing with the NCUC. Duke Energy 
Progress cannot predict the outcome of this matter.

2018 South Carolina Rate Case

On November 8, 2018, Duke Energy Progress filed an application with the 

PSCSC for a rate increase for retail customers of approximately $59 million, 
which represents an approximate 10.3% increase in annual base revenues. The 
request for rate increase was driven by capital investments and environmental 
compliance progress made by Duke Energy Progress since its previous rate 
case, including the further implementation of Duke Energy Progress’ generation 
modernization program, which consists of retiring, replacing and upgrading 
generation plants, investments in customer service technologies and continued 
investments in base work to maintain its transmission and distribution systems. 
The request included a decrease resulting from the Tax Act of $17 million to 
reflect the change in ongoing tax expense, primarily the reduction in the federal 
income tax rate from 35% to 21%. The request also included $10 million to 
return EDIT resulting from the federal tax rate change and deferred revenues 
since January 2018 related to the change (EDIT Rider) and a $12 million 
increase due to the expiration of EDITs related to reductions in North Carolina 
state income taxes allocable to South Carolina.

Duke Energy Progress also requested approval of its proposed GIP, 
approval of a Prepaid Advantage Program and a variety of accounting orders 
related to ongoing costs for environmental compliance, including recovery over 
a five-year period of $51 million of deferred coal ash related compliance costs, 
AMI deployment, grid investments between rate changes and regulatory asset 
treatment related to the retirement of a generating plant located in Asheville, 
North Carolina. Finally, Duke Energy Progress sought approval to establish a 
reserve and accrual for end-of-life nuclear costs for materials and supplies and 
nuclear fuel. On March 8, 2019, the ORS moved to establish a new and separate 
hearing docket to review and consider the GIP proposed by Duke Energy Progress. 
Subsequently, on March 12, 2019, the ORS and Duke Energy Carolinas executed 
a Stipulation resolving the ORS’s motion, and Duke Energy Progress agreed to the 
Stipulation, as did other parties in the rate case. The Stipulation provides that 
costs incurred for the GIP after January 1, 2019, would be deferred with a return, 
with all costs subject to evaluation in a future rate proceeding. The Stipulation 
was approved by the PSCSC on June 19, 2019. On December 16, 2019, Duke 
Energy Progress and Duke Energy Carolinas filed a Joint Petition to Establish an

through which Duke Energy Progress and Duke Energy Carolinas would provide 
interested stakeholders information on the companies’ grid activities. The PSCSC 
requested parties comment on procedural matters by January 31; accordingly, 
various groups filed comments, none of which opposed an informational docket. 
Duke Energy Progress cannot predict the outcome of this matter.

After hearings in April 2019, the PSCSC issued an order on May 21, 2019, 
which included a return on equity of 9.5% and a capital structure of 53% equity 
and 47% debt. The order also included the following material components:

• Approval of recovery of $4 million of coal ash costs over a five-year 

period with a return at Duke Energy Progress’ WACC;

• Denial of recovery of $65 million of certain coal ash costs deemed to be 
related to the Coal Ash Act and incremental to the federal CCR rule;

• Approval of a $17 million decrease to base rates to reflect the change 

in ongoing tax expense, primarily the reduction in the federal income tax 
rate from 35% to 21%;

• Approval of a $12 million decrease through the EDIT Tax Savings Rider 
resulting from the federal tax rate change and deferred revenues since 
January 2018 related to the change, to be returned in accordance with 
ARAM for protected EDIT, over a 20-year period for unprotected EDIT 
associated with Property, Plant and Equipment, over a five-year period 
for unprotected EDIT not associated with Property, Plant and Equipment 
and over a three-year period for the deferred revenues; and

• Approval of a $12 million increase due to the expiration of EDIT related to 
reductions in the North Carolina state income tax rate from 6.9% to 2.5%.

As a result of the order, revised customer rates were effective June 1, 
2019. On May 31, 2019, Duke Energy Progress filed a Petition for Rehearing 
or Reconsideration of that order contending substantial rights of Duke Energy 
Progress were prejudiced by unlawful, arbitrary and capricious rulings by 
the commission on certain issues presented in the proceeding. On June 19, 
2019, the PSCSC issued a Directive denying Duke Energy Progress’ request 
to rehear or reconsider the commission’s rulings on certain issues presented 
in the proceeding including coal ash remediation and disposal costs, return 
on equity and the recovery of a return on deferred operation and maintenance 
expenses, but allowing additional litigation-related costs. As a result of the 
Directive allowing litigation-related costs, customer rates were revised effective 
July 1, 2019. An order detailing the commission’s decision in the Directive was 
issued on October 18, 2019. Duke Energy Progress filed a notice of appeal on 
November 15, 2019, with the South Carolina Supreme Court. The ORS filed a 
Notice of Cross Appeal on November 20, 2019. On January 8, 2020, Duke Energy 
Progress and the ORS filed a joint motion to extend briefing schedule deadlines. 
Appellant briefs are due on March 2, 2020, and Appellee response briefs are 
on May 15, 2020. On February 12, 2020, Duke Energy Progress and the ORS 
filed a joint motion to extend briefing deadlines by 30 days. Based on legal 
analysis and the filing of the appeal, Duke Energy Progress has not recorded an 
adjustment for its deferred coal ash costs. Duke Energy Progress cannot predict 
the outcome of this matter.

Western Carolinas Modernization Plan

On November 4, 2015, Duke Energy Progress announced a Western 

Carolinas Modernization Plan, which included retirement of the existing 
Asheville coal-fired plant, the construction of two 280 MW combined-cycle 
natural gas plants having dual-fuel capability, with the option to build a third 

natural gas simple cycle unit in 2023 based upon the outcome of initiatives to 
reduce the region’s power demand. The plan also included upgrades to existing 
transmission lines and substations, installation of solar generation and a pilot 
battery storage project. Duke Energy Progress worked with the local natural gas 
distribution company to upgrade and lease an existing natural gas pipeline to 
serve the natural gas plant. The lease for the new pipeline became effective on 
March 2, 2019.

On March 28, 2016, the NCUC issued an order approving a CPCN for the 
new combined-cycle natural gas plants, but is requiring Duke Energy Progress 
to refile for CPCN approval for the contingent simple cycle unit. On March 28, 
2019, Duke Energy Progress filed an annual progress report for the construction 
of the combined-cycle plants with the NCUC, with an estimated cost of 
$893 million.

On December 27, 2019, Asheville Combined Cycle Power Block 1 and the 

common systems that serve both combined cycle units went into commercial 
operation. Power Block 1 consists of the Unit 5 Combustion Turbine and Unit 6 
Steam Turbine Generator (which together form the first combined cycle unit 
approved in the CPCN Order). Power Block 2 consists of the Unit 7 Combustion 
Turbine and Unit 8 Steam Turbine Generator (which together form the second 
combined cycle unit approved in the CPCN Order). Duke Energy Progress 
placed the Unit 7 Combustion Turbine portion of Power Block 2 into commercial 
operation in simple-cycle mode on January 15, 2020. Duke Energy Progress 
currently expects to place the Unit 8 Steam Turbine Generator into commercial 
operation in the first quarter of 2020, after final testing has been completed.
On October 8, 2018, Duke Energy Progress filed an application with the 

NCUC for a CPCN to construct the Hot Springs Microgrid Solar and Battery 
Storage Facility. On March 22, 2019, Duke Energy Progress and the Public 
Staff filed a Joint Proposed Order. On May 10, 2019, the NCUC issued an Order 
Granting Certificate of Public Convenience and Necessity with Conditions. On 
November 19, 2019, Duke Energy Progress filed a semiannual progress report 
for its Hot Springs Microgrid Solar and Battery Storage Facility. As required by 
an NCUC order issued December 6, 2019, an updated progress report was filed 
on January 15, 2020. Construction is expected to begin in March 2020 with 
commercial operation expected to begin in September 2020.

The carrying value of the 376-MW Asheville coal-fired plant, including 

associated ash basin closure costs, of $214 million and $327 million is 
included in Generation facilities to be retired, net on Duke Energy Progress’ 
Consolidated Balance Sheets as of December 31, 2019, and 2018, respectively. 
Duke Energy Progress’ request for a regulatory asset at the time of retirement 
with amortization over a 10-year period was approved by the NCUC on 
February 23, 2018. Duke Energy Progress retired the Asheville coal-fired plant 
on January 29, 2020.

FERC Return on Equity Complaint

On October 11, 2019, NCEMPA filed a complaint at FERC against Duke 
Energy Progress pursuant to Section 206 of the Federal Power Act (FPA). The 
complaint alleges that the return on equity component in the formula rate 
contained within the Full Requirements Power Purchase Agreement (FRPPA) is 
unjust and unreasonable. The FRPPA’s return on equity is 11% as applied to 
the Production Capacity Rate for the full requirements service provided by Duke 
Energy Progress. The complaint does not definitively propose a replacement 
return on equity. Under FPA Section 206, the earliest refund effective date that 
FERC can establish is the date of the filing of the complaint. The complaint 
could raise risks across the Duke Energy Progress wholesale business because, 
depending on how FERC treats NCEMPA’s complaint, other parties may come 
forward with similar complaints. Duke Energy Progress cannot predict the 
outcome of this matter.

Storm Restoration Cost Recovery

In September 2017, Duke Energy Florida’s service territory suffered 

significant damage from Hurricane Irma, resulting in approximately 1 million 
customers experiencing outages. In the fourth quarter of 2017, Duke Energy 
Florida also incurred preparation costs related to Hurricane Nate. On 
December 28, 2017, Duke Energy Florida filed a petition with the FPSC to recover 
incremental storm restoration costs for Hurricane Irma and Hurricane Nate 
and to replenish the storm reserve. On February 6, 2018, the FPSC approved a 
stipulation that would apply tax savings resulting from the Tax Act toward storm 
costs effective January 2018 in lieu of implementing a storm surcharge. On 
May 31, 2018, Duke Energy Florida filed a petition for approval of actual storm 
restoration costs and associated recovery process related to Hurricane Irma 
and Hurricane Nate. The petition sought the approval for the recovery in the 
amount of $510 million in actual recoverable storm restoration costs, including 
the replenishment of Duke Energy Florida’s storm reserve of $132 million, and 
the process for recovering these recoverable storm costs. On August 20, 2018, 

the FPSC approved Duke Energy Florida’s unopposed Motion for Continuance 
filed August 17, 2018, to allow for an evidentiary hearing in this matter. On 
January 28, 2019, Duke Energy Florida made a supplemental filing to reduce 
the total storm cost recovery from $510 million to $508 million. On April 3, 
2019, the FPSC issued an Order abating all remaining filing dates. On April 9, 
2019, Duke Energy Florida filed an unopposed motion to approve a settlement 
agreement resolving all outstanding issues in this docket. On June 13, 2019, 
the FPSC issued its order approving the settlement agreement. The Storm Cost 
Settlement Agreement obligates Duke Energy Florida to capitalize $18 million 
of storm costs and remove $6 million of operating and maintenance expense, 
thereby reducing the requested storm cost recovery amount by $24 million. 
Duke Energy Florida will also implement process changes with respect to storm 
cost restoration. At December 31, 2019, and December 31, 2018, Duke Energy 
Florida’s Consolidated Balance Sheets included approximately $43 million and 
$217 million, respectively, of recoverable costs under the FPSC’s storm rule in 
Regulatory assets within Current Assets and Other Noncurrent Assets related to 
storm recovery for Hurricane Irma and Hurricane Nate.

when Hurricane Michael made landfall as a Category 5 hurricane with maximum 
sustained winds of 160 mph. The storm caused catastrophic damage from 
wind and storm surge, particularly from Panama City Beach to Mexico Beach, 
resulting in widespread outages and significant damage to transmission and 
distribution facilities across the central Florida Panhandle. In response to 
Hurricane Michael, Duke Energy Florida restored service to approximately 
72,000 customers. Total estimated incremental operation and maintenance and 
capital costs are $311 million. Approximately $107 million and $35 million of 
the costs are included in Net property, plant and equipment on the Consolidated 
Balance Sheets as of December 31, 2019, and December 31, 2018, 
respectively. Approximately $204 million and $165 million of costs are included 
in Regulatory assets within Current Assets and Other Noncurrent Assets on 
the Consolidated Balance Sheets as of December 31, 2019, and December 31, 
2018, respectively, representing recoverable costs under the FPSC’s storm rule 
and Duke Energy Florida’s OATT formula rates.

Duke Energy Florida filed a petition with the FPSC on April 30, 2019, to 
recover the retail portion of incremental storm restoration costs for Hurricane 
Michael. On June 11, 2019, the FPSC approved the petition for recovery of 
incremental storm restoration costs related to Hurricane Michael. The FPSC 
also approved the stipulation Duke Energy Florida filed, which will allow Duke 
Energy Florida to use the tax savings resulting from the Tax Act to recover these 
storm costs in lieu of implementing a storm surcharge. Approved storm costs 
are currently expected to be fully recovered by approximately year-end 2021. 
On November 22, 2019, Duke Energy Florida filed a petition for approval of 
actual retail recoverable storm restoration costs related to Hurricane Michael in 
the amount of $191 million plus interest. An Order Establishing Procedure was 
issued on January 30, 2020, and hearings are scheduled to begin September 15, 
2020. Duke Energy Florida cannot predict the outcome of this matter.

Hurricane Dorian

In September 2019, Duke Energy Florida’s service territory was threatened 
by Hurricane Dorian with landfall as a possible Category 5 hurricane. For several 
days, various forecasts and models predicted significant impact to Duke Energy 
Florida’s service territory; accordingly, Duke Energy Florida incurred costs to 
secure necessary resources to be prepared for that potential impact. Although 
Hurricane Dorian never made landfall in Florida, its effects were still felt, and 
outages did occur. Preparations were required so that, if Hurricane Dorian had 
made landfall and impacts had been more severe, Duke Energy Florida would 
have been prepared to restore its customers’ power in a timely fashion.

Total current estimated incremental costs are approximately $167 million. 

These costs are included in Regulatory assets within Current Assets and Other 
Noncurrent Assets on the Consolidated Balance Sheets as of December 31, 
2019, representing recoverable costs under the FPSC’s storm rule and Duke 
Energy Florida’s OATT formula rates. On December 19, 2019, Duke Energy 
Florida filed a petition with the FPSC to recover the estimated retail portion of 
these costs, consistent with the provisions in the 2017 Settlement. The request 
seeks recovery over a 12-month period beginning in March 2020. The final 
actual amount will be filed later in 2020 and a hearing will be held at the FPSC 
to determine the final amount of incremental costs. Duke Energy Florida cannot 
predict the outcome of this matter.

Tax Act

Pursuant to Duke Energy Florida’s 2017 Settlement, on May 31, 2018, 

Duke Energy Florida filed a petition related to the Tax Act, which included 
revenue requirement impacts of annual tax savings of $134 million and 
estimated annual amortization of EDIT of $67 million for a total of $201 million. 

Of this amount, $50 million would be offset by accelerated depreciation of 
Crystal River 4 and 5 coal units and an estimated $151 million would be offset 
by Hurricane Irma storm cost recovery as explained in the Storm Restoration 
Cost Recovery section above. On December 27, 2018, Duke Energy Florida 
filed actual EDIT balances and amortization based on its 2017 filed tax return. 
This increased the revenue requirement impact of the amortization of EDIT by 
$4 million, from $67 million to $71 million, which increased the total storm 
amortization from $151 million to $155 million. On January 8, 2019, the FPSC 
approved a joint motion by Duke Energy Florida and the Office of Public Counsel 
resolving all stipulated positions. As part of that stipulation, Duke Energy Florida 
agreed to seek a Private Letter Ruling (PLR) from the IRS on its treatment of cost 
of removal (COR) as mostly protected by tax normalization rules. If the IRS rules 
that COR is not protected by tax normalization rules, then Duke Energy Florida 
will make a final adjustment to the amortization of EDIT and an adjustment 
to the storm recovery amount retroactive to January 2018. The IRS has 
communicated that it will not issue individual PLRs on the treatment of COR. 
Rather, the IRS is drafting a notice that will request comments on a number 
of issues, including COR, and the IRS plans to issue industrywide guidance on 
those issues. Duke Energy Florida cannot predict the outcome of this matter.

Citrus County CC

Construction of the 1,640-MW combined-cycle natural gas plant in Citrus 

County, Florida, began in October 2015 with an estimated cost of $1.5 billion, 
including AFUDC. Both units came on-line in the fourth quarter of 2018. The 
ultimate cost of the facility was estimated to be $1.6 billion, and Duke Energy 
Florida recorded Impairment charges on Duke Energy’s Consolidated Statements of 
Operations of $60 million in the fourth quarter of 2018 for the overrun. In the year 
ended December 31, 2019, Duke Energy Florida recorded a $36 million reduction 
to the prior-year impairment due to a decrease in the cost estimate of the Citrus 
County CC, primarily related to the settlement agreement with Fluor, the EPC 
contractor. This adjustment reduced the estimated cost of the facility to $1.5 billion.

Solar Base Rate Adjustment

On July 31, 2018, Duke Energy Florida petitioned the FPSC to include 

in base rates the revenue requirements for its first two solar generation 
projects, the Hamilton Project and the Columbia Project, as authorized by 
the 2017 Settlement. The Hamilton Project, which was placed into service on 
December 22, 2018, has an annual retail revenue requirement of $15 million. At 
its October 30, 2018, Agenda Conference, the FPSC approved the rate increase 
related to the Hamilton Project to go into effect beginning with the first billing 
cycle in January 2019 under its file and suspend authority, and revised customer 
rates became effective in January 2019. The Columbia Project has a projected 
annual revenue requirement of $14 million and a projected in-service date in 
early 2020; the associated rate increase would take place with the first month’s 
billing cycle after the Columbia Project goes into service. On April 2, 2019, the 
commission approved both solar projects as filed.

On March 25, 2019, Duke Energy Florida petitioned the FPSC to include 

in base rates the revenue requirements for its next wave of solar generation 
projects, the Trenton, Lake Placid and DeBary Solar Projects, as authorized by 
the 2017 Settlement. The annual retail revenue requirement for the Trenton and 
Lake Placid Projects is $13 million and $8 million, respectively, and were placed 
into service in December 2019 with rates taking effect in January 2020. The 
DeBary Project has a projected annual revenue requirement of $11 million and a 
projected in-service date in the first half of 2020. The associated rate increase 
would take place with the first month’s billing cycle after each solar generation 
project goes into service. On July 22, 2019, the FPSC issued an order approving 
Duke Energy Florida’s request.

On May 29, 2019, Duke Energy Florida entered into a Decommissioning 

Services Agreement for the accelerated decommissioning of the Crystal 
River Unit 3 nuclear power station located in Citrus County, Florida, with ADP 
CR3, LLC and ADP SF1, LLC, each of which is a wholly owned subsidiary of 
Accelerated Decommissioning Partners, LLC, a joint venture between NorthStar 
Group Services, Inc. and Orano USA LLC. Closing of this agreement is contingent 
upon the approval of the NRC and FPSC. If approved, the decommissioning will

be accelerated starting in 2020 and continuing through 2027, rather than the 
expected time frame under SAFSTOR of starting in 2067 and ending in 2074. 
Duke Energy Florida expects that the assets of the Nuclear Decommissioning 
Trust Fund will be sufficient to cover the contract price. On July 10, 2019, Duke 
Energy Florida petitioned the FPSC for approval of the agreement. Duke Energy 
Florida cannot predict the outcome of this matter.

On June 1, 2017, Duke Energy Ohio filed with the PUCO a request for 
a standard service offer in the form of an Electric Security Plan (ESP). On 
February 15, 2018, the procedural schedule was suspended to facilitate ongoing 
settlement discussions. On April 13, 2018, Duke Energy Ohio filed a Motion 
to consolidate this proceeding with several other cases pending before the 
PUCO, including, but not limited to, its Electric Base Rate Case. Additionally, 
on April 13, 2018, Duke Energy Ohio, along with certain intervenors, filed a 
Stipulation and Recommendation (Stipulation) with the PUCO resolving certain 
issues in this proceeding. The term of the ESP would be from June 1, 2018, 
to May 31, 2025, and included continuation of market-based customer rates 
through competitive procurement processes for generation, continuation and 
expansion of existing rider mechanisms and proposed new rider mechanisms 
relating to regulatory mandates, costs incurred to enhance the customer 
experience and transform the grid and a service reliability rider for vegetation 
management. The Stipulation established a regulatory model for the next 
seven years via the approval of the ESP and continued the current model for 
procuring supply for non-shopping customers, including recovery mechanisms. 
On December 19, 2018, the PUCO approved the Stipulation without material 
modification. Several parties, including the OCC, filed applications for rehearing. 
On February 6, 2019, the PUCO granted the parties rehearing. The PUCO issued 
its Second Entry on Rehearing on July 17, 2019, upholding its December 19, 
2018, order and denying all assignments of error raised by the non-stipulating 
parties. On October 11, 2019, the OCC filed its Third Application for Rehearing 
arguing the PUCO erred in finding OCC’s Second Application for Rehearing 
as improper. Duke Energy Ohio filed its Memorandum Contra on October 21, 
2019. The PUCO denied OCC’s Third Application for Rehearing as a matter of 
law. On September 13, 2019, Interstate Gas Supply/Retail Supply Association 
filed appeals to the Ohio Supreme Court claiming the PUCO’s order was in 
error because it approved unsupported charges to competitive suppliers 
and cost subsidies shopping customers pay for non-shopping customers. 
On September 16, 2019, the OCC filed an appeal challenging the PUCO’s 
approval of OVEC recovery through Rider PSR alleging the FPA pre-empts the 
commission’s jurisdiction and that the record does not support finding that Rider 
PSR results in a limitation on shopping. Appellant briefs were filed on January 6, 
2020. Appellee briefs will be due March 16, 2020. Duke Energy Ohio cannot 
predict the outcome of this matter.

Electric Base Rate Case

Duke Energy Ohio filed with the PUCO an electric distribution base rate 
case application and supporting testimony in March 2017. Duke Energy Ohio 
requested an estimated annual increase of approximately $15 million and a 
return on equity of 10.4%. The application also included requests to continue 
certain current riders and establish new riders. On September 26, 2017, 
the PUCO staff filed a report recommending a revenue decrease between 
approximately $18 million and $29 million and a return on equity between 
9.22% and 10.24%. On April 13, 2018, Duke Energy Ohio filed a Motion 
to consolidate this proceeding with several other cases pending before the 
PUCO. On April 13, 2018, Duke Energy Ohio, along with certain intervenors, 
filed the Stipulation with the PUCO resolving numerous issues including those 
in this base rate proceeding. Major components of the Stipulation related to 
the base distribution rate case included a $19 million decrease in annual base 
distribution revenue with a return on equity unchanged from the current rate 
of 9.84% based upon a capital structure of 50.75% equity and 49.25% debt. 
Upon approval of new rates, Duke Energy Ohio’s rider for recovering its initial 
SmartGrid implementation ended as these costs would be recovered through 
base rates. The Stipulation also renewed 14 existing riders, some of which 

were included in the company’s ESP, and added two new riders including 
the Enhanced Service Reliability Rider to recover vegetation management 
costs not included in base rates, up to $10 million per year (operation and 
maintenance only) and the PowerForward Rider to recover costs incurred to 
enhance the customer experience and further transform the grid (operation and 
maintenance and capital). In addition to the changes in revenue attributable 
to the Stipulation, Duke Energy Ohio’s capital-related riders, including the 
Distribution Capital Investments Rider, began to reflect the lower federal 
income tax rate associated with the Tax Act with updates to customers’ bills 
beginning April 1, 2018. This change reduced electric revenue by approximately 
$20 million on an annualized basis. On December 19, 2018, the PUCO approved 
the Stipulation without material modification. New base rates were implemented 
effective January 2, 2019. Several parties including the OCC filed applications 
for rehearing. On February 6, 2019, the PUCO granted the parties rehearing. 
The PUCO issued its Second Entry on Rehearing on July 17, 2019, upholding its 
December 19, 2018, order and denying all assignments of error raised by the 
non-stipulating parties. On October 11, 2019, the OCC filed its Third Application 
for Rehearing arguing the PUCO erred in finding OCC’s Second Application for 
Rehearing as improper. Duke Energy Ohio filed its Memorandum Contra on 
October 21, 2019. The PUCO denied OCC’s Third Application for Rehearing as 
a matter of law. On September 13, 2019, Interstate Gas Supply/Retail Supply 
Association filed appeals to the Ohio Supreme Court claiming the PUCO’s order 
was in error because it approved unsupported charges to competitive suppliers 
and cost subsidies shopping customers pay for non-shopping customers. 
On September 16, 2019, the OCC filed an appeal challenging the PUCO’s 
approval of OVEC recovery through Rider PSR alleging the FPA pre-empts the 
commission’s jurisdiction and that the record does not support finding that Rider 
PSR results in a limitation on shopping. Appellant briefs were filed on January 6, 
2020. Appellee briefs will be due March 16, 2020. Duke Energy Ohio cannot 
predict the outcome of this matter.

Ohio Valley Electric Corporation

On March 31, 2017, Duke Energy Ohio filed for approval to adjust 
its existing Rider PSR to pass through net costs related to its contractual 
entitlement to capacity and energy from the generating assets owned by 
OVEC. Duke Energy Ohio sought deferral authority for net costs incurred from 
April 1, 2017, until the new rates under Rider PSR were put into effect. On 
April 13, 2018, Duke Energy Ohio filed a Motion to consolidate this proceeding 
with several other cases currently pending before the PUCO. Also, on April 13, 
2018, Duke Energy Ohio, along with certain intervenors, filed a Stipulation 
with the PUCO resolving numerous issues including those related to Rider 
PSR. The Stipulation activated Rider PSR for recovery of net costs incurred 
from January 1, 2018, through May 2025. On December 19, 2018, the PUCO 
approved the Stipulation without material modification. The PSR rider became 
effective April 1, 2019. Several parties, including the OCC, filed applications 
for rehearing. On February 6, 2019, the PUCO granted the parties rehearing. 
The PUCO issued its Second Entry on Rehearing on July 17, 2019, upholding its 
December 19, 2018, order and denying all assignments of error raised by the 
non-stipulating parties. On October 11, 2019, the OCC filed its Third Application 
for Rehearing arguing the PUCO erred in finding OCC’s Second Application for 
Rehearing as improper. Duke Energy Ohio filed its Memorandum Contra on 
October 21, 2019. The PUCO denied OCC’s Third Application for Rehearing as 
a matter of law. On September 13, 2019, Interstate Gas Supply/Retail Supply 
Association filed appeals to the Ohio Supreme Court claiming the PUCO’s order

On July 23, 2019, an Ohio bill was signed into law that became effective 
January 1, 2020. Among other things, the bill allows for recovery of prudently 
incurred costs, net of any revenues, for Ohio investor-owned utilities that are 
participants under the OVEC power agreement. The recovery shall be through 
a non-bypassable rider that is to replace any existing recovery mechanism 
approved by the PUCO and will remain in place through 2030. The amounts 
recoverable from customers will be subject to an annual cap, with incremental 
costs that exceed such cap eligible for deferral and recovery subject to review. 
See Note 18 for additional discussion of Duke Energy Ohio’s ownership interest 
in OVEC.

Tax Act – Ohio

On July 25, 2018, Duke Energy Ohio filed an application to establish 
a new rider to implement the benefits of the Tax Act for electric distribution 
customers. The new rider will flow through to customers the benefit of the 
lower statutory federal tax rate from 35% to 21% since January 1, 2018, all 
future benefits of the lower tax rates and a full refund of deferred income taxes 
collected at the higher tax rates in prior years. Deferred income taxes subject 
to normalization rules will be refunded consistent with federal law and deferred 
income taxes not subject to normalization rules will be refunded over a 10-year 
period. Duke Energy Ohio’s transmission rates reflect lower federal income tax 
but guidance from FERC on amortization of both protected and unprotected 
transmission-related EDITs is still pending. On October 24, 2018, the PUCO 
issued a Finding and Order that, among other things, directed all utilities over 
which the commission has ratemaking authority to file an application to pass 
the benefits of the Tax Act to customers by January 1, 2019, unless otherwise 
exempted or directed by the PUCO. Duke Energy Ohio’s July 25, 2018, filing for 
electric distribution operations is consistent with the commission’s October 24, 
2018, Finding and Order and no further action is needed. On February 20, 2019, 
the PUCO approved the application without material modification. Rates became 
effective March 1, 2019.

On December 21, 2018, Duke Energy Ohio filed an application to change 

its base rates and establish a new rider to implement the benefits of the Tax Act 
for natural gas customers. Duke Energy Ohio requested commission approval 
to implement the changes and rider effective April 1, 2019. The new rider 
will flow through to customers the benefit of the lower statutory federal tax 
rate from 35% to 21% since January 1, 2018, all future benefits of the lower 
tax rates and a full refund of deferred income taxes collected at the higher 
tax rates in prior years. Deferred income taxes subject to normalization rules 
will be refunded consistent with federal law and deferred income taxes not 
subject to normalization rules will be refunded over a 10-year period. The PUCO 
established a procedural schedule and testimony was filed on July 31, 2019. 
An evidentiary hearing occurred on August 7, 2019. Initial briefs were filed on 
September 11, 2019. Reply briefs were filed on September 25, 2019. Duke 
Energy Ohio cannot predict the outcome of this matter.

Energy Efficiency Cost Recovery

On March 28, 2014, Duke Energy Ohio filed an application for recovery of 
program costs, lost distribution revenue and performance incentives related to 
its energy efficiency and peak demand reduction programs. These programs are 
undertaken to comply with environmental mandates set forth in Ohio law. The 
PUCO approved Duke Energy Ohio’s application but found that Duke Energy Ohio 

was not permitted to use banked energy savings from previous years in order to 
calculate the amount of allowed incentive. This conclusion represented a change 
to the cost recovery mechanism that had been agreed upon by intervenors and 
approved by the PUCO in previous cases. The PUCO granted the applications for 
rehearing filed by Duke Energy Ohio and an intervenor. On January 6, 2016, Duke 
Energy Ohio and the PUCO Staff entered into a stipulation, pending the PUCO’s 
approval, to resolve issues related to performance incentives and the PUCO 
Staff audit of 2013 costs, among other issues. In December 2015, based upon 
the stipulation, Duke Energy Ohio re-established approximately $20 million of 
the revenues that had been previously reversed. On October 26, 2016, the PUCO 
issued an order approving the stipulation without modification. In December 
2016, the PUCO granted the intervenors request for rehearing for the purpose 
of further review. On April 10, 2019, the PUCO issued an Entry on Rehearing 
denying the rehearing applications.

On June 15, 2016, Duke Energy Ohio filed an application for approval of a 
three-year energy efficiency and peak demand reduction portfolio of programs. 
A stipulation and modified stipulation were filed on December 22, 2016, and 
January 27, 2017, respectively. Under the terms of the stipulations, which 
included support for deferral authority of all costs and a cap on shared savings 
incentives, Duke Energy Ohio has offered its energy efficiency and peak demand 
reduction programs throughout 2017. On February 3, 2017, Duke Energy Ohio 
filed for deferral authority of its costs incurred in 2017 in respect of its proposed 
energy efficiency and peak demand reduction portfolio. On September 27, 2017, 
the PUCO issued an order approving a modified stipulation. The modifications 
impose an annual cap of approximately $38 million on program costs and 
shared savings incentives combined, but allowed for Duke Energy Ohio to file for 
a waiver of costs in excess of the cap in 2017. The PUCO approved the waiver 
request for 2017 up to a total cost of $56 million. On November 21, 2017, the 
PUCO granted Duke Energy Ohio’s and intervenor’s applications for rehearing 
of the September 27, 2017, order. On January 10, 2018, the PUCO denied 
the OCC’s application for rehearing of the PUCO order granting Duke Energy 
Ohio’s waiver request; however, a decision on Duke Energy Ohio’s application 
for rehearing remains pending. On October 15, 2019, the Ohio Supreme Court 
issued an Opinion regarding a similar cap on energy efficiency imposed by the 
PUCO on Ohio Edison Company finding the PUCO lacked statutory authority 
to impose a cap on cost recovery. On December 9, 2019, and in response to 
recent changes to Ohio Law, the OCC filed a motion to eliminate shared savings 
from Duke Energy Ohio’s energy efficiency calculation beginning in 2020. Duke 
Energy Ohio filed a memorandum contra and a notice of additional authority 
on December 16, 2019, arguing OCC’s interpretation is incorrect and that the 
commission should amend its September 27, 2017 order to comply with recent 
precedent. Duke Energy Ohio cannot predict the outcome of this matter.

2014 Electric Security Plan

On May 30, 2018, the PUCO approved an extension of Duke Energy 
Ohio’s then-current ESP, including all terms and conditions thereof, excluding 
an extension of Duke Energy Ohio’s Distribution Capital Investment Rider. 
Following rehearing, on July 25, 2018, the PUCO granted the request and 
allowed a continuing cap on recovery under Rider DCI. The orders were upheld 
on rehearing requested by the Ohio Manufacturers’ Association (OMA) and OCC. 
The time period for parties to file for rehearing or appeal has expired.

In 2018, the OMA and OCC filed separate appeals of PUCO’s approval 
of Duke Energy Ohio’s ESP with the Ohio Supreme Court, challenging PUCO’s 
approval of Duke Energy Ohio’s Rider PSR as a placeholder and its Rider DCI 
to recover incremental revenue requirement for distribution capital since Duke 
Energy Ohio’s last base rate case. The Ohio Supreme Court issued an order on 
March 13, 2019, for the appellants to show cause why the appeals should not

Ohio’s current ESP. The OCC and OMA made the requested filings on March 20, 
2019, and Duke Energy Ohio filed its response on March 27, 2019. Subsequent 
to OCC and OMA making the requested filings, the Ohio Supreme Court 
dismissed the appeals as moot on May 8, 2019.

Natural Gas Pipeline Extension

Duke Energy Ohio is proposing to install a new natural gas pipeline 

(the Central Corridor Project) in its Ohio service territory to increase system 
reliability and enable the retirement of older infrastructure. Duke Energy Ohio 
currently estimates the pipeline development costs and construction activities 
will range from $163 million to $245 million in direct costs (excluding overheads 
and AFUDC). On January 20, 2017, Duke Energy Ohio filed an amended 
application with the Ohio Power Siting Board (OPSB) for approval of one of two 
proposed routes. A public hearing was held on June 15, 2017. In April 2018, 
Duke Energy Ohio filed a motion with OPSB to establish a procedural schedule 
and filed supplemental information supporting its application. On December 18, 
2018, the OPSB established a procedural schedule that included a local public 
hearing on March 21, 2019. An evidentiary hearing began on April 9, 2019, and 
concluded on April 11, 2019. Briefs were filed on May 13, 2019, and reply briefs 
were filed on June 10, 2019. On November 21, 2019, the OPSB approved Duke 
Energy Ohio’s application subject to 41 conditions on construction. Applications 
for rehearing were filed by several stakeholders on December 23, 2019, arguing 
that the OPSB approval was incorrect. Duke Energy Ohio filed a memorandum 
contra on January 2, 2020. On January 17, 2020, the OPSB granted rehearing 
for the purpose of further consideration. Construction of the pipeline extension 
is expected to be completed before the 2021/2022 winter season. Duke Energy 
Ohio cannot predict the outcome of this matter.

2012 Natural Gas Rate Case/MGP Cost Recovery

As part of its 2012 natural gas base rate case, Duke Energy Ohio has 
approval to defer and recover costs related to environmental remediation at 
two sites (East End and West End) that housed former MGP operations. Duke 
Energy Ohio has made annual applications for recovery of these deferred costs. 
Duke Energy Ohio has collected approximately $55 million in environmental 
remediation costs between 2009 through 2012 through a separate rider, 
Rider MGP, which is currently suspended. Duke Energy Ohio has made annual 
applications with the PUCO to recover its incremental remediation costs 
consistent with the PUCO’s directive in Duke Energy Ohio’s 2012 natural gas 
rate case. To date, the PUCO has not ruled on Duke Energy Ohio’s annual 
applications for the calendar years 2013 through 2017. On September 28, 
2018, the staff of the PUCO issued a report recommending a disallowance of 
approximately $12 million of the $26 million in MGP remediation costs incurred 
between 2013 through 2017 that staff believes are not eligible for recovery. 
Staff interprets the PUCO’s 2012 Order granting Duke Energy Ohio recovery of 
MGP remediation as limiting the recovery to work directly on the East End and 
West End sites. On October 30, 2018, Duke Energy Ohio filed reply comments 
objecting to the staff’s recommendations and explaining, among other things, 
the obligation Duke Energy Ohio has under Ohio law to remediate all areas 
impacted by the former MGPs and not just physical property that housed the 
former plants and equipment. To date, the PUCO has not ruled on Duke Energy 
Ohio’s applications. On March 29, 2019, Duke Energy Ohio filed its annual 
application to recover incremental remediation expense for the calendar year 
2018 seeking recovery of approximately $20 million in remediation costs. 
On July 12, 2019, the staff recommended a disallowance of approximately 
$11 million for work that staff believes occurred in areas not authorized for 
recovery. Additionally, staff recommended that any discussion pertaining to 

Duke Energy Ohio’s recovery of ongoing MGP costs should be directly tied to or 
netted against insurance proceeds collected by Duke Energy Ohio. An evidentiary 
hearing began on November 18, 2019, and concluded November 21, 2019. 
Initial briefs were filed on January 17, 2020, and reply briefs were filed on 
February 14, 2020. Duke Energy Ohio cannot predict the outcome of this matter.
The 2012 PUCO order also contained conditional deadlines for completing 

the MGP environmental investigation and remediation costs at the MGP sites. 
Subsequent to the order, the deadline was extended to December 31, 2019. On 
May 10, 2019, Duke Energy Ohio filed an application requesting a continuation 
of its existing deferral authority for MGP remediation and investigation that 
must occur after December 31, 2019. On September 13, 2019, intervenor 
comments were filed opposing Duke Energy Ohio’s request for continuation of 
existing deferral authority and on October 2, 2019, Duke Energy Ohio filed reply 
comments. Duke Energy Ohio cannot predict the outcome of this matter.

Duke Energy Kentucky Natural Gas Base Rate Case

On August 31, 2018, Duke Energy Kentucky filed an application with 
the KPSC requesting an increase in natural gas base rates of approximately 
$11 million, an approximate 11.1% average increase across all customer 
classes. The increase was net of approximately $5 million in annual savings as 
a result of the Tax Act. The drivers for this case were capital invested since Duke 
Energy Kentucky’s last rate case in 2009. Duke Energy Kentucky also sought 
implementation of a Weather Normalization Adjustment Mechanism, amortization 
of regulatory assets and to implement the impacts of the Tax Act, prospectively. On 
January 30, 2019, Duke Energy Kentucky entered into a settlement agreement with 
the Attorney General of Kentucky, the only intervenor in the case. The settlement 
provided for an approximate $7 million increase in natural gas base revenue, a 
return on equity of 9.7% and approval of the proposed Weather Normalization 
Mechanism. A hearing was held on February 5, 2019. The commission issued its 
order approving the settlement without material modification on March 27, 2019. 
Revised customer rates were effective April 1, 2019.

Duke Energy Kentucky Electric Base Rate Case

On September 3, 2019, Duke Energy Kentucky filed a rate case with the 

KPSC requesting an increase in electric base rates of approximately $46 million, 
which represents an approximate 12.5% increase across all customer classes. 
The request for rate increase is driven by increased investment in utility plant 
since the last electric base rate case in 2017. Duke Energy Kentucky seeks 
to implement a Storm Deferral Mechanism that will enable Duke Energy 
Kentucky to defer actual costs incurred for major storms that are over or under 
amounts in base rates. In response to large customers’ desire to have access 
to renewable resources, Duke Energy Kentucky is proposing a Green Source 
Advantage tariff designed for those large customers that wish to invest in 
renewable energy resources to meet sustainability goals. Duke Energy Kentucky 
is proposing an electric vehicle (EV) infrastructure pilot and modest incentives 
to assist customers in investing in EV technologies. Additionally, Duke Energy 
Kentucky is proposing to build an approximate 3.4 MW distribution battery 
energy storage system to be attached to Duke Energy Kentucky’s distribution 
system providing frequency regulation and enhanced reliability to Kentucky 
customers. The commission issued a procedural schedule with two rounds of 
discovery and opportunities for intervenor and rebuttal testimony. The Kentucky 
Attorney General filed its testimony recommending an increase of approximately 
$26 million. On January 31, 2020, Duke Energy Kentucky filed rebuttal testimony 
updating its rate increase calculations to approximately $44 million. Hearings 
began on February 19, 2020. Duke Energy Kentucky anticipates that rates will go 
into effect in the second quarter of 2020. Duke Energy Kentucky cannot predict 
the outcome of this matter.

PART IIDUKE ENERGY CORPORATION • DUKE ENERGY CAROLINAS, LLC • PROGRESS ENERGY, INC. • DUKE ENERGY PROGRESS, LLC •  DUKE ENERGY FLORIDA, LLC • DUKE ENERGY OHIO, INC. • DUKE ENERGY INDIANA, LLC • PIEDMONT NATURAL GAS COMPANY, INC.Combined Notes to Consolidated Financial Statements – (Continued)2019 Indiana Rate Case

On July 2, 2019, Duke Energy Indiana filed a general rate case with the 
IURC, its first general rate case in Indiana in 16 years, for a rate increase for 
retail customers of approximately $395 million. The request for rate increase 
is driven by strategic investments to generate cleaner electricity, improve 
reliability and serve a growing customer base. The request is premised upon a 
Duke Energy Indiana rate base of $10.2 billion as of December 31, 2018, and 
adjusted for projected changes through December 31, 2020. On September 9, 
2019, Duke Energy Indiana revised its revenue request from $395 million 
to $393 million and filed updated testimony for the Retail Rate Case. The 
updated filing reflects a clarification in the presentation of Utility Receipts Tax, 
a $2 million reduction in the revenue requirement for revenues that will remain 
in riders and changes to allocation of revenue requirements within rate classes. 
The Utility Receipts Tax is currently embedded in base rates and rider rates. The 
proposed treatment is to include the Utility Receipts Tax as a line item on the 
customer bill rather than included in rates. The request is an approximate 15% 
increase in retail revenues and approximately 17% when including estimated 
Utility Receipts Tax. The rebuttal case, filed on December 4, 2019, updated the 
requested revenue requirement to result in a 15.6% or $396 million average 

retail rate increase, including the impacts of the Utility Receipts Tax. The 
commission determined to take two issues out of the rate case and place them 
in separate subdocket proceedings due to the complexity of the rate case. The 
commission moved the request for electric transportation pilot and future coal 
ash recovery issues to separate subdockets. Coal ash expenditures prior to 
2019 are still included in the rate case. Hearings concluded on February 7, 2020 
and rates are expected to be effective by mid-2020. Duke Energy Indiana cannot 
predict the outcome of these matters.

Edwardsport IGCC Plant

On September 20, 2018, Duke Energy Indiana, the Indiana Office of Utility 

Consumer Counselor, the Duke Industrial Group and Nucor Steel – Indiana 
entered into a settlement agreement to resolve IGCC ratemaking issues for 
calendar years 2018 and 2019. The agreement will remain in effect until new 
rates are established in Duke Energy Indiana’s next base rate case, which was 
filed on July 2, 2019, with rates to be effective in mid-2020. An evidentiary 
hearing was held in December 2018, and on June 5, 2019, the IURC issued an 
order approving the 2018 Settlement Agreement.

• Continuation of the IMR mechanism; and

On April 30, 2019, Piedmont filed a petition under the IMR mechanism 
to update rates, based on the eligible capital investments closed to integrity 
and safety projects over the six-month period ending March 31, 2019. The 
NCUC approved the petition on May 29, 2019, and rates became effective 
June 1, 2019. The effect of the update was an increase to annual revenues of 
approximately $9 million. These revenues, along with eligible spending for the 
three months ended June 30, 2019, were subsequently included in base rates 
effective November 1, 2019, as part of the 2019 North Carolina Rate Case.

On October 31, 2019, Piedmont filed a petition under the IMR mechanism 
to update rates, based on the eligible capital investments closed to integrity and 
safety projects over the three-month period ending September 30, 2019. The 
NCUC approved the petition on December 3, 2019, and rates became effective 
December 1, 2019. The effect of the update was an increase to annual revenues 
of approximately $11 million.

Tennessee Integrity Management Rider Filing

In November 2019, Piedmont filed a petition with the TPUC under the 
IMR mechanism to collect an additional $4 million in annual revenues, effective 
January 2020, based on the eligible capital spending on integrity and safety 
projects over the 12-month period ending October 31, 2019. A procedural 
schedule has not yet been set for this matter. Piedmont cannot predict the 
outcome of this matter.

2019 North Carolina Rate Case

On April 1, 2019, Piedmont filed an application with the NCUC, its first 
general rate case in North Carolina in six years, for a rate increase for retail 
customers of approximately $83 million, which represents an approximate 
9% increase in retail revenues. The request for rate increase was driven by 
significant infrastructure upgrade investments (plant additions) since the last 
general rate case through June 30, 2019, offset by savings that customers will 
begin receiving due to federal and state tax reform. Approximately half of the 
plant additions being included in rate base are categories of plant investment 
not covered under the IMR mechanism, which was originally approved as part of 
the 2013 North Carolina Rate Case.

On August 13, 2019, Piedmont, the Public Staff, and two groups 

representing industrial customers filed an Agreement and Stipulation Settlement 
resolving issues in the base rate proceeding, which included a return on 
equity of 9.7% and a capital structure of 52% equity and 48% debt. The 
North Carolina Attorney General’s Office did not support the settlement. Other 
major components of the Stipulation included:

• An annual increase in revenues of $109 million before consideration of 

riders associated with federal and state tax reform;

• A decrease through a rider mechanism of $23 million per year to return 
unprotected federal EDIT over a five-year period and deferred revenues 
related to the federal rate reduction of $37 million to be returned over 
one year;

• A decrease through a rider mechanism of $21 million per year related 
to reductions in the North Carolina state income tax rate to be returned 
over a three-year period;

• An overall cap on net revenue increase of $83 million. This will impact 
Piedmont beginning November 1, 2022, only if the company does not 
file another general rate case in the interim;

• Establishment of a new deferral mechanism for certain Distribution 
Integrity Management Program (DIMP) operations and maintenance 
expenses incurred effective November 1, 2019, and thereafter.

An evidentiary hearing began on August 19, 2019. On October 31, 2019, 

the NCUC approved the Stipulation and the revised customer rates were 
effective November 1, 2019.

OTHER REGULATORY MATTERS

Atlantic Coast Pipeline, LLC

On September 2, 2014, Duke Energy, Dominion Energy, Inc. (Dominion), 
Piedmont and Southern Company Gas announced the formation of Atlantic Coast 
Pipeline, LLC (ACP) to build and own the proposed Atlantic Coast Pipeline (ACP 
pipeline), an approximately 600-mile interstate natural gas pipeline running 
from West Virginia to North Carolina. The ACP pipeline is designed to meet, 
in part, the needs identified by Duke Energy Carolinas, Duke Energy Progress 
and Piedmont. Dominion will be responsible for building and operating the ACP 
pipeline and holds a leading ownership percentage in ACP of 48%. Duke Energy 
owns a 47% interest, which is accounted for as an equity method investment 
through its Gas Utilities and Infrastructure segment. Southern Company Gas 
maintains a 5% interest. See Notes 13 and 18 for additional information 
related to Duke Energy’s ownership interest. Duke Energy Carolinas, Duke 
Energy Progress and Piedmont, among others, will be customers of the pipeline. 
Purchases will be made under several 20-year supply contracts, subject to state 
regulatory approval.

In 2018, the FERC issued a series of Notices to Proceed, which authorized 

the project to begin certain construction-related activities along the pipeline 
route, including supply header and compressors. On May 11, 2018, and 
October 19, 2018, FERC issued Notices to Proceed allowing full construction 
activities in all areas of West Virginia except in the Monongahela National Forest. 
On July 24, 2018, FERC issued a Notice to Proceed allowing full construction 
activities along the project route in North Carolina. On October 19, 2018, the 
conditions to effectiveness of the Virginia 401 water quality certification were 
satisfied and, following receipt of the Virginia 401 certification, ACP filed a 
request for FERC to issue a Notice to Proceed with full construction activities in 
Virginia. Due to legal challenges not directly related to the request for a Notice to 
Proceed in Virginia, this request is still pending.

ACP is the subject of challenges in state and federal courts and agencies, 

including, among others, challenges of the project’s biological opinion (BiOp) 
and incidental take statement (ITS), crossings of the Blue Ridge Parkway, 
the Appalachian Trail, and the Monongahela and George Washington National 
Forests, the project’s U.S. Army Corps of Engineers (USACE) 404 permit, the 
project’s air permit for a compressor station at Buckingham, Virginia, the 
FERC Environmental Impact Statement order and the FERC order approving 
the Certificate of Public Convenience and Necessity. Each of these challenges 
alleges non-compliance on the part of federal and state permitting authorities 
and adverse ecological consequences if the project is permitted to proceed. 
Since December 2018, notable developments in these challenges include a stay 
in December 2018 issued by the U.S. Court of Appeals for the Fourth Circuit 
(Fourth Circuit) and the same court’s July 26, 2019, vacatur of the project’s 
BiOp and ITS (which stay and subsequent vacatur halted most project 
construction activity), a Fourth Circuit decision vacating the project’s permits 
to cross the Monongahela and George Washington National Forests and the 
Appalachian Trail, the Fourth Circuit’s remand to USACE of ACP’s Huntington 

132

PART IIDUKE ENERGY CORPORATION • DUKE ENERGY CAROLINAS, LLC • PROGRESS ENERGY, INC. • DUKE ENERGY PROGRESS, LLC •  DUKE ENERGY FLORIDA, LLC • DUKE ENERGY OHIO, INC. • DUKE ENERGY INDIANA, LLC • PIEDMONT NATURAL GAS COMPANY, INC.Combined Notes to Consolidated Financial Statements – (Continued)District 404 verification, the Fourth Circuit’s remand to the National Park 
Service of ACP’s Blue Ridge Parkway right-of-way and the most recent vacatur 
of the air permit for a compressor station at Buckingham, Virginia. ACP is 
vigorously defending these challenges and coordinating with the federal and 
state authorities which are the direct parties to the challenges. The Solicitor 
General of the United States and ACP filed petitions for certiorari to the Supreme 
Court of the United States on June 25, 2019, regarding the Appalachian Trail 
crossing and certiorari was granted on October 4, 2019. The Supreme Court 
hearing is scheduled for February 24, 2020, and a ruling is expected in the 
second quarter of 2020. ACP is also evaluating possible legislative and other 
remedies to this issue.

In anticipation of the Fourth Circuit’s vacatur of the BiOp and ITS, ACP 

and the FWS commenced work in mid-May of 2019 to set the basis for a 
reissued BiOp and ITS. On February 10, 2020, FERC issued a letter to FWS 
requesting the re-initiation of formal consultation in support of reissuing the 
BiOp and ITS. ACP continues coordinating and working with FWS and other 
parties in preparation for a reissuance of the BiOp and ITS.

ACP triggered the Adverse Government Actions (AGA) clause of its 
agreements with its customers in December 2019. Formal negotiations have 
commenced regarding pricing and construction timing, among other items, and 
are expected to be finalized in the first quarter of 2020. The results of these 
negotiations will directly impact the expected future cash flows of this project.
Given the legal challenges and ongoing discussions with customers, ACP 
expects mechanical completion of the full project in late 2021 with in-service 
likely in the first half of 2022.

The delays resulting from the legal challenges described above have 
also impacted the cost for the project. Project cost is approximately $8 billion, 
excluding financing costs. This estimate is based on the current facts available 
around construction costs and timelines, and is subject to future changes as 
those facts develop. Abnormal weather, work delays (including delays due to 
judicial or regulatory action) and other conditions may result in cost or schedule 
modifications, a suspension of AFUDC for ACP and/or impairment charges 
potentially material to Duke Energy’s cash flows, financial position and results 
of operations.

Duke Energy’s investment in ACP was $1.2 billion at December 31, 
2019. Duke Energy evaluated this investment for impairment at December 31, 
2019, and determined that fair value approximated carrying value and therefore 
no impairment was necessary. Duke Energy also has a guarantee agreement 
supporting its share of the ACP revolving credit facility. Duke Energy’s maximum 

exposure to loss under the terms of the guarantee is $827 million, which 
represents 47% of the outstanding borrowings under the credit facility as of 
December 31, 2019. See Note 13 for additional information.

Constitution Pipeline Company, LLC

Duke Energy owned a 24% ownership interest in Constitution, which is 
accounted for as an equity method investment. Constitution was a natural gas 
pipeline project slated to transport natural gas supplies from the Marcellus 
supply region in northern Pennsylvania to major northeastern markets. The 
pipeline was to be constructed and operated by Williams Partners L.P., which 
had a 41% ownership share. The remaining interest was held by Cabot Oil 
and Gas Corporation and WGL Holdings, Inc. In December 2014, Constitution 
received approval from the FERC to construct and operate the proposed 
pipeline. However, since April 2016, Constitution had stopped construction and 
discontinued capitalization of future development costs due to permitting delays 
and adverse rulings by regulatory agencies and courts.

In late 2019, Constitution determined that its principal shipper would not 
agree to an amended precedent agreement. Without such an amendment, the 
project would no longer be viable and, as of February 5, 2020, the Constitution 
partners formally resolved to initiate the dissolution of Constitution, and to 
terminate the Constitution Pipeline project. In the fourth quarter of 2019, Duke 
Energy recorded an OTTI of $25 million related to Constitution within Equity in 
earnings of unconsolidated affiliates on Duke Energy’s Consolidated Statements 
of Income, resulting in the full write-down of Duke Energy’s investment 
in Constitution. See Notes 13 and 18 for additional information related to 
ownership interest and carrying value of the investment.

Potential Coal Plant Retirements

The Subsidiary Registrants periodically file IRPs with their state regulatory 

commissions. The IRPs provide a view of forecasted energy needs over a long 
term (10 to 20 years) and options being considered to meet those needs. IRPs 
filed by the Subsidiary Registrants included planning assumptions to potentially 
retire certain coal-fired generating facilities in North Carolina and Indiana earlier 
than their current estimated useful lives. Duke Energy continues to evaluate 
the potential need to retire these coal-fired generating facilities earlier than the 
current estimated useful lives and plans to seek regulatory recovery for amounts 
that would not be otherwise recovered when any of these assets are retired.

The table below contains the net carrying value of generating facilities planned for retirement or included in recent IRPs as evaluated for potential retirement. 

Dollar amounts in the table below are included in Net property, plant and equipment on the Consolidated Balance Sheets as of December 31, 2019, and exclude 
capitalized asset retirement costs.

5.  COMMITMENTS AND CONTINGENCIES

INSURANCE

General Insurance

The Duke Energy Registrants have insurance and reinsurance coverage 

either directly or through indemnification from Duke Energy’s captive insurance 
company, Bison, and its affiliates, consistent with companies engaged in 
similar commercial operations with similar type properties. The Duke Energy 
Registrants’ coverage includes (i) commercial general liability coverage for 
liabilities arising to third parties for bodily injury and property damage; (ii) 
workers’ compensation; (iii) automobile liability coverage; and (iv) property 
coverage for all real and personal property damage. Real and personal property 
damage coverage excludes electric transmission and distribution lines, but 
includes damages arising from boiler and machinery breakdowns, earthquakes, 
flood damage and extra expense, but not outage or replacement power 
coverage. All coverage is subject to certain deductibles or retentions, sublimits, 
exclusions, terms and conditions common for companies with similar types of 
operations. The Duke Energy Registrants self-insure their electric transmission 
and distribution lines against loss due to storm damage and other natural 
disasters. As discussed further in Note 4, Duke Energy Florida maintains a 
storm damage reserve and has a regulatory mechanism to recover the cost of 
named storms on an expedited basis.

The cost of the Duke Energy Registrants’ coverage can fluctuate from year 
to year reflecting claims history and conditions of the insurance and reinsurance 
markets.

In the event of a loss, terms and amounts of insurance and reinsurance 
available might not be adequate to cover claims and other expenses incurred. 
Uninsured losses and other expenses, to the extent not recovered by other 
sources, could have a material effect on the Duke Energy Registrants’ results of 
operations, cash flows or financial position. Each company is responsible to the 
extent losses may be excluded or exceed limits of the coverage available.

Nuclear Insurance

Duke Energy Carolinas owns and operates McGuire and Oconee and 

operates and has a partial ownership interest in Catawba. McGuire and 
Catawba each have two reactors. Oconee has three reactors. The other joint 
owners of Catawba reimburse Duke Energy Carolinas for certain expenses 
associated with nuclear insurance per the Catawba joint owner agreements.

Duke Energy Progress owns and operates Robinson, Brunswick and Harris. 

Robinson and Harris each have one reactor. Brunswick has two reactors.

Duke Energy Florida owns Crystal River Unit 3, which permanently ceased 

operation in 2013 and reached a SAFSTOR condition in January 2018 after the 
successful transfer of all used nuclear fuel assemblies to an on-site dry cask 
storage facility.

In the event of a loss, terms and amounts of insurance available might not 

be adequate to cover property damage and other expenses incurred. Uninsured 
losses and other expenses, to the extent not recovered by other sources, could 

134

have a material effect on Duke Energy Carolinas’, Duke Energy Progress’ and 
Duke Energy Florida’s results of operations, cash flows or financial position. 
Each company is responsible to the extent losses may be excluded or exceed 
limits of the coverage available.

Nuclear Liability Coverage

The Price-Anderson Act requires owners of nuclear reactors to provide for 

public nuclear liability protection per nuclear incident up to a maximum total 
financial protection liability. The maximum total financial protection liability, 
which is approximately $13.9 billion, is subject to change every five years for 
inflation and for the number of licensed reactors. Total nuclear liability coverage 
consists of a combination of private primary nuclear liability insurance coverage 
and a mandatory industry risk-sharing program to provide for excess nuclear 
liability coverage above the maximum reasonably available private primary 
coverage. The U.S. Congress could impose revenue-raising measures on the 
nuclear industry to pay claims.

Primary Liability Insurance

Duke Energy Carolinas and Duke Energy Progress have purchased the 
maximum reasonably available private primary nuclear liability insurance as 
required by law, which is $450 million per station. Duke Energy Florida has 
purchased $100 million primary nuclear liability insurance in compliance with 
the law.

Excess Liability Program

This program provides $13.5 billion of coverage per incident through 

the Price-Anderson Act’s mandatory industrywide excess secondary financial 
protection program of risk pooling. This amount is the product of potential 
cumulative retrospective premium assessments of $138 million times the 
current 98 licensed commercial nuclear reactors in the U.S. Under this program, 
licensees could be assessed retrospective premiums to compensate for public 
nuclear liability damages in the event of a nuclear incident at any licensed 
facility in the U.S. Retrospective premiums may be assessed at a rate not 
to exceed $20.5 million per year per licensed reactor for each incident. The 
assessment may be subject to state premium taxes.

Nuclear Property and Accidental Outage Coverage

Duke Energy Carolinas, Duke Energy Progress and Duke Energy Florida 

are members of Nuclear Electric Insurance Limited (NEIL), an industry mutual 
insurance company, which provides property damage, nuclear accident 
decontamination and premature decommissioning insurance for each station 
for losses resulting from damage to its nuclear plants, either due to accidents 
or acts of terrorism. Additionally, NEIL provides accidental outage coverage for 
losses in the event of a major accidental outage at an insured nuclear station.

PART IIDUKE ENERGY CORPORATION • DUKE ENERGY CAROLINAS, LLC • PROGRESS ENERGY, INC. • DUKE ENERGY PROGRESS, LLC •  DUKE ENERGY FLORIDA, LLC • DUKE ENERGY OHIO, INC. • DUKE ENERGY INDIANA, LLC • PIEDMONT NATURAL GAS COMPANY, INC.Combined Notes to Consolidated Financial Statements – (Continued)Pursuant to regulations of the NRC, each company’s property damage 
insurance policies provide that all proceeds from such insurance be applied, 
first, to place the plant in a safe and stable condition after a qualifying accident 
and second, to decontaminate the plant before any proceeds can be used for 
decommissioning, plant repair or restoration.

Losses resulting from acts of terrorism are covered as common 
occurrences, such that if terrorist acts occur against one or more commercial 
nuclear power plants insured by NEIL within a 12-month period, they would be 
treated as one event and the owners of the plants where the act occurred would 
share one full limit of liability. The full limit of liability is currently $3.2 billion. 
NEIL sublimits the total aggregate for all of their policies for non-nuclear 
terrorist events to approximately $1.8 billion.

Each nuclear facility has accident property damage, nuclear accident 
decontamination and premature decommissioning liability insurance from NEIL 
with limits of $1.5 billion, except for Crystal River Unit 3. Crystal River Unit 3’s limit 
is $50 million and is on an actual cash value basis. All nuclear facilities except 
for Catawba and Crystal River Unit 3 also share an additional $1.25 billion 
nuclear accident insurance limit above their dedicated underlying limit. This 
shared additional excess limit is not subject to reinstatement in the event of 
a loss. Catawba has a dedicated $1.25 billion of additional nuclear accident 
insurance limit above its dedicated underlying limit. Catawba and Oconee also 
have an additional $750 million of non-nuclear accident property damage limit. All 
coverages are subject to sublimits and significant deductibles.

NEIL’s Accidental Outage policy provides some coverage, similar to 
business interruption, for losses in the event of a major accident property 
damage outage of a nuclear unit. Coverage is provided on a weekly limit basis 
after a significant waiting period deductible and at 100% of the applicable 
weekly limits for 52 weeks and 80% of the applicable weekly limits for up to 
the next 110 weeks. Coverage is provided until these applicable weekly periods 
are met, where the accidental outage policy limit will not exceed $490 million 
for McGuire and Catawba, $462 million for Brunswick and Harris, $406 million 
for Oconee and $364 million for Robinson. NEIL sublimits the accidental outage 
recovery up to the first 104 weeks of coverage not to exceed $328 million 
from non-nuclear accidental property damage. Coverage amounts decrease 
in the event more than one unit at a station is out of service due to a common 
accident. All coverages are subject to sublimits and significant deductibles.

Potential Retroactive Premium Assessments

In the event of NEIL losses, NEIL’s board of directors may assess 
member companies’ retroactive premiums of amounts up to 10 times their 

annual premiums for up to six years after a loss. NEIL has never exercised this 
assessment. The maximum aggregate annual retrospective premium obligations 
for Duke Energy Carolinas, Duke Energy Progress and Duke Energy Florida are 
$155 million, $94 million and $1 million, respectively. Duke Energy Carolinas’ 
maximum assessment amount includes 100% of potential obligations to NEIL 
for jointly owned reactors. Duke Energy Carolinas would seek reimbursement 
from the joint owners for their portion of these assessment amounts.

ENVIRONMENTAL

The Duke Energy Registrants are subject to federal, state and local laws 
regarding air and water quality, hazardous and solid waste disposal, coal ash 
and other environmental matters. These laws can be changed from time to 
time, imposing new obligations on the Duke Energy Registrants. The following 
environmental matters impact all of the Duke Energy Registrants.

Remediation Activities

In addition to the ARO recorded as a result of various environmental 
regulations, discussed in Note 10, the Duke Energy Registrants are responsible 
for environmental remediation at various sites. These include certain properties 
that are part of ongoing operations and sites formerly owned or used by Duke 
Energy entities. These sites are in various stages of investigation, remediation 
and monitoring. Managed in conjunction with relevant federal, state and 
local agencies, remediation activities vary based upon site conditions and 
location, remediation requirements, complexity and sharing of responsibility. 
If remediation activities involve joint and several liability provisions, strict 
liability, or cost recovery or contribution actions, the Duke Energy Registrants 
could potentially be held responsible for environmental impacts caused by 
other potentially responsible parties and may also benefit from insurance 
policies or contractual indemnities that cover some or all cleanup costs. 
Liabilities are recorded when losses become probable and are reasonably 
estimable. The total costs that may be incurred cannot be estimated because 
the extent of environmental impact, allocation among potentially responsible 
parties, remediation alternatives and/or regulatory decisions have not yet been 
determined at all sites. Additional costs associated with remediation activities 
are likely to be incurred in the future and could be significant. Costs are typically 
expensed as Operation, maintenance and other in the Consolidated Statements 
of Operations unless regulatory recovery of the costs is deemed probable.

The following tables contain information regarding reserves for probable and estimable costs related to the various environmental sites. These reserves are 

recorded in Accounts payable within Current Liabilities and Other within Other Noncurrent Liabilities on the Consolidated Balance Sheets.

Duke Energy Carolinas and Duke Energy Progress

NCDEQ Closure Litigation

The Coal Ash Act requires CCR surface impoundments in North Carolina 

to be closed, with the closure method and timing based on a risk ranking 
classification determined by legislation or state regulators. The NCDEQ 
previously classified the impoundments at Allen, Belews Creek, Rogers, 
Marshall, Mayo and Roxboro as low risk. The Coal Ash Act allowed a range of 
closure options for low risk rated basins. On April 1, 2019, NCDEQ issued a 
closure determination (NCDEQ’s April 1 Order) requiring Duke Energy Carolinas 
and Duke Energy Progress to excavate all remaining coal ash impoundments 
at these facilities. On April 26, 2019, Duke Energy Carolinas and Duke 
Energy Progress filed Petitions for Contested Case Hearings in the Office of 
Administrative Hearings to challenge NCDEQ’s April 1 Order. On May 9, 2019, 
NCDEQ issued a supplemental order requiring that closure plans be submitted 
on December 31, 2019, but providing that the corrective action plans are not 
due until March 31, 2020. Duke Energy Carolinas and Duke Energy Progress filed 
amended petitions on May 24, 2019, incorporating the May 9, 2019, order.
On December 31, 2019, the parties executed a settlement agreement 
resolving the closure method for each of these sites. Duke Energy Carolinas 
and Duke Energy Progress agreed to excavate seven of the nine remaining coal 
ash basins at these sites with ash moved to on-site lined landfills, including 
two at Allen, one at Belews Creek, one at Mayo, one at Roxboro, and two at 
Rogers. At the two remaining basins at Marshall and Roxboro, uncapped basin 
ash will be excavated and moved to lined landfills. Those portions of the basins 
at Marshall and Roxboro, which were previously filled with ash and on which 
permitted facilities were constructed, will not be disturbed and will be closed 
pursuant to other state regulations. On February 5, 2020, the North Carolina 
Superior court entered a consent order, after which this litigation was dismissed 
on February 11, 2020.

Coal Ash Insurance Coverage Litigation

In March 2017, Duke Energy Carolinas and Duke Energy Progress filed 
a civil action in the North Carolina Superior Court against various insurance 
providers. The lawsuit seeks payment for coal ash-related liabilities covered 
by third-party liability insurance policies. The insurance policies were issued 
between 1971 and 1986 and provide third-party liability insurance for 
property damage. The civil action seeks damages for breach of contract and 
indemnification for costs arising from the Coal Ash Act and the EPA CCR rule 
at 15 coal-fired plants in North Carolina and South Carolina. Despite a stay of 
the litigation from May 2019 through September 2019 to allow the parties to 
discuss potential resolution, no resolution was reached, and litigation resumed. 
In February and March 2020, the Court will hear arguments on numerous cross 
motions filed by the parties to seek legal determinations concerning, among

NCDEQ State Enforcement Actions

In the first quarter of 2013, SELC sent notices of intent to sue Duke Energy 
Carolinas and Duke Energy Progress related to alleged CWA violations from coal 
ash basins at two coal-fired power plants in North Carolina. The NCDEQ filed 
enforcement actions against Duke Energy Carolinas and Duke Energy Progress 
alleging violations of water discharge permits and North Carolina groundwater 
standards. The cases have been consolidated and are being heard before a 
single judge in the North Carolina Superior Court.

On August 16, 2013, the NCDEQ filed an enforcement action against Duke 

Energy Carolinas and Duke Energy Progress related to the remaining coal-fired 
power plants in North Carolina, alleging violations of the CWA and violations 
of the North Carolina groundwater standards. Both of these cases have been 
assigned to the judge handling the enforcement actions discussed above. SELC 
is representing several environmental groups who have been permitted to 
intervene in these cases.

The court issued orders in 2016 granting Motions for Partial Summary 

Judgment for seven of the 14 North Carolina plants with coal ash basins 
named in the enforcement actions. On February 13, 2017, the court issued 
an order denying motions for partial summary judgment brought by both the 
environmental groups and Duke Energy Carolinas and Duke Energy Progress for 
the remaining seven plants. On March 15, 2017, Duke Energy Carolinas and 
Duke Energy Progress filed a Notice of Appeal with the North Carolina Court of 
Appeals to challenge the trial court’s order. The parties were unable to reach an 
agreement at mediation in April 2017 and submitted briefs to the trial court on 
remaining issues to be tried. On August 1, 2018, the Court of Appeals dismissed 
the appeal.

Pursuant to the terms of the December 31, 2019, settlement agreement, 

discussed above, between Duke Energy Carolinas, Duke Energy Progress, 
NCDEQ and the community groups represented by the SELC, this litigation was 
dismissed on February 5, 2020, upon entry of the consent order in the North 
Carolina Superior Court.

Federal Citizens Suits

On June 13, 2016, Roanoke River Basin Association (RRBA) filed a 
federal citizen suit in the Middle District of North Carolina alleging unpermitted 
discharges to surface water and groundwater violations at the Mayo Plant. On 
August 19, 2016, Duke Energy Progress filed a Motion to Dismiss. On April 26, 
2017, the court entered an order dismissing four of the claims in the federal 
citizen suit. Two claims relating to alleged violations of National Pollution 
Discharge Elimination System (NPDES) permit provisions survived the motion 
to dismiss, and Duke Energy Progress filed its response on May 10, 2017. 
Duke Energy Progress and RRBA each filed motions for summary judgment on 
March 23, 2018.

On May 16, 2017, RRBA filed a federal citizen suit in the U.S. District 
Court for the Middle District of North Carolina, which asserts two claims relating 
to alleged violations of NPDES permit provisions at the Roxboro Plant and one 
claim relating to the use of nearby water bodies. Duke Energy Progress and 
RRBA each filed motions for summary judgment on April 17, 2018.

On May 8, 2018, on motion from Duke Energy Progress, the court ordered 

trial in both of the above matters to be consolidated. On April 5, 2019, Duke 
Energy Progress filed a motion to stay the case following the NCDEQ’s April 1 
Order. On August 2, 2019, the court ordered that this case is stayed.

Duke Energy Progress and Duke Energy Florida

U.S. District Court for the Middle District of North Carolina for alleged violations 
at Duke Energy Carolinas’ Belews Creek under the CWA. Duke Energy Carolinas’ 
answer to the complaint was filed on August 27, 2018. On October 10, 2018, 
Duke Energy Carolinas filed Motions to Dismiss for lack of standing, Motion for 
Judgment on the Pleadings and Motion to Stay Discovery. On January 9, 2019, the 
court entered an order denying Duke Energy Carolinas’ motion to stay discovery. 
There has been no ruling on the other pending motions. On April 5, 2019, Duke 
Energy Carolinas filed a motion to stay the case following the NCDEQ’s April 1 
Order. On August 2, 2019, the court ordered that this case is stayed.

On December 31, 2019, Duke Energy Carolinas, Duke Energy Progress, 

the NCDEQ and various community groups including RRBA entered into a 
comprehensive settlement that, among other things, resolves the method of 
closure at the Mayo, Roxboro and Belews Creek ash basins. On February 5, 
2020, the North Carolina Superior Court entered a consent order confirming 
the terms of the settlement agreement, upon which RRBA filed stipulations on 
February 11, 2020 voluntarily dismissing all three of these federal citizen suits 
with prejudice.

Asbestos-related Injuries and Damages Claims

Duke Energy Carolinas has experienced numerous claims for 

indemnification and medical cost reimbursement related to asbestos exposure. 
These claims relate to damages for bodily injuries alleged to have arisen from 
exposure to or use of asbestos in connection with construction and maintenance 
activities conducted on its electric generation plants prior to 1985. As of 
December 31, 2019, there were 123 asserted claims for non-malignant cases 
with the cumulative relief sought of up to $32 million and 49 asserted claims for 
malignant cases with the cumulative relief sought of up to $16 million. Based on 
Duke Energy Carolinas’ experience, it is expected that the ultimate resolution of 
most of these claims likely will be less than the amount claimed.

Duke Energy Carolinas has recognized asbestos-related reserves of 
$604 million and $630 million at December 31, 2019, and 2018, respectively. 
These reserves are classified in Other within Other Noncurrent Liabilities and 
Other within Current Liabilities on the Consolidated Balance Sheets. These 
reserves are based upon Duke Energy Carolinas’ best estimate for current and 
future asbestos claims through 2039 and are recorded on an undiscounted 
basis. In light of the uncertainties inherent in a longer-term forecast, 
management does not believe they can reasonably estimate the indemnity and 
medical costs that might be incurred after 2039 related to such potential claims. 
It is possible Duke Energy Carolinas may incur asbestos liabilities in excess of 
the recorded reserves.

Duke Energy Carolinas has third-party insurance to cover certain losses 

related to asbestos-related injuries and damages above an aggregate self-
insured retention. Duke Energy Carolinas’ cumulative payments began to exceed 
the self-insurance retention in 2008. Future payments up to the policy limit will 
be reimbursed by the third-party insurance carrier. The insurance policy limit 
for potential future insurance recoveries indemnification and medical cost claim 
payments is $747 million in excess of the self-insured retention. Receivables for 
insurance recoveries were $742 million and $739 million at December 31, 2019, 
and 2018, respectively. These amounts are classified in Other within Other 
Noncurrent Assets and Receivables within Current Assets on the Consolidated 
Balance Sheets. Duke Energy Carolinas is not aware of any uncertainties 
regarding the legal sufficiency of insurance claims. Duke Energy Carolinas 
believes the insurance recovery asset is probable of recovery as the insurance 
carrier continues to have a strong financial strength rating.

Spent Nuclear Fuel Matters

On June 18, 2018, Duke Energy Progress and Duke Energy Florida sued 

the U.S. in the U.S. Court of Federal Claims for damages incurred for the period 
2014 through 2018. The lawsuit claimed the Department of Energy breached a 
contract in failing to accept spent nuclear fuel under the Nuclear Waste Policy 
Act of 1982 and asserted damages for the cost of on-site storage in the amount 
of $100 million and $203 million for Duke Energy Progress and Duke Energy 
Florida, respectively. Discovery is ongoing and a trial is expected to occur in 
early 2021.

Duke Energy Florida

Fluor Contract Litigation

On January 29, 2019, Fluor filed a breach of contract lawsuit in the U.S. 

District Court for the Middle District of Florida against Duke Energy Florida 
related to an EPC agreement for the CC natural gas plant in Citrus County, 
Florida. Fluor filed an amended complaint on February 13, 2019. Fluor’s 
multicount complaint seeks civil, statutory and contractual remedies related to 
Duke Energy Florida’s $67 million draw in early 2019, on Fluor’s letter of credit 
and offset of invoiced amounts. Duke Energy Florida moved to dismiss all counts 
of Fluor’s amended complaint, and on April 16, 2019, the court dismissed 
Fluor’s complaint without prejudice. On April 26, 2019, Fluor filed a second 
amended complaint.

On August 1, 2019, Duke Energy Florida and Fluor reached a settlement to 
resolve the pending litigation and other outstanding issues related to completing 
the Citrus County CC. Pursuant to the terms of the settlement, Fluor filed a 
notice of voluntary dismissal, and on August 27, 2019, the court dismissed the 
case with prejudice. As a result of the settlement with Fluor, Duke Energy Florida 
recorded a $36 million reduction to a prior-year impairment within Impairment 
charges on Duke Energy’s Consolidated Statements of Operations in 2019.

Other Litigation and Legal Proceedings

The Duke Energy Registrants are involved in other legal, tax and regulatory 

proceedings arising in the ordinary course of business, some of which involve 
significant amounts. The Duke Energy Registrants believe the final disposition of 
these proceedings will not have a material effect on their results of operations, 
cash flows or financial position.

The table below presents recorded reserves based on management’s best 
estimate of probable loss for legal matters, excluding asbestos-related reserves. 
Reserves are classified on the Consolidated Balance Sheets in Other within 
Other Noncurrent Liabilities and Other within Current Liabilities. The reasonably 
possible range of loss in excess of recorded reserves is not material, other than 
as described above.

Gas Supply and Capacity Contracts

Duke Energy Ohio and Piedmont routinely enter into long-term natural 

gas supply commodity and capacity commitments and other agreements that 
commit future cash flows to acquire services needed in their businesses. These 
commitments include pipeline and storage capacity contracts and natural 
gas supply contracts to provide service to customers. Costs arising from the 
natural gas supply commodity and capacity commitments, while significant, are 
pass-through costs to customers and are generally fully recoverable through 
the fuel adjustment or PGA procedures and prudence reviews in North Carolina 
and South Carolina and under the Tennessee Incentive Plan in Tennessee. 
In the Midwest, these costs are recovered via the Gas Cost Recovery Rate in 
Ohio or the Gas Cost Adjustment Clause in Kentucky. The time periods for fixed 
payments under pipeline and storage capacity contracts are up to 15 years. The 
time periods for fixed payments under natural gas supply contracts are up to six 
years. The time period for the natural gas supply purchase commitments is up 
to 11 years.

Certain storage and pipeline capacity contracts require the payment of 

demand charges that are based on rates approved by the FERC in order to 
maintain rights to access the natural gas storage or pipeline capacity on a 
firm basis during the contract term. The demand charges that are incurred in 
each period are recognized in the Consolidated Statements of Operations and 
Comprehensive Income as part of natural gas purchases and are included in 
Cost of natural gas.

LEASES

As described in Note 1, Duke Energy adopted the revised accounting guidance for Leases effective January 1, 2019, using the modified retrospective method of 
adoption, which does not require restatement of prior year reported results. Adoption of the new standard resulted in the recording of ROU assets and operating lease 
liabilities as follows:

As part of its operations, Duke Energy leases certain aircraft, space on 

communication towers, industrial equipment, fleet vehicles, fuel transportation 
(barges and railcars), land and office space under various terms and expiration 
dates. Additionally, Duke Energy Carolinas, Duke Energy Progress and Duke 
Energy Indiana have finance leases related to firm natural gas pipeline 
transportation capacity. Duke Energy Progress and Duke Energy Florida have 
entered into certain PPAs, which are classified as finance and operating leases.
Duke Energy has certain lease agreements, which include variable 
lease payments that are based on the usage of an asset. These variable lease 
payments are not included in the measurement of the ROU assets or operating 
lease liabilities on the Consolidated Financial Statements.

Certain Duke Energy lease agreements include options for renewal and 
early termination. The intent to renew a lease varies depending on the lease 
type and asset. Renewal options that are reasonably certain to be exercised are 
included in the lease measurements. The decision to terminate a lease early 
is dependent on various economic factors. No termination options have been 
included in any of the lease measurements.

Duke Energy Carolinas entered into a sale-leaseback arrangement in 
December 2019, to construct and occupy an office tower. The lease agreement 
was evaluated as a sale-leaseback of real estate and it was determined that 
the transaction did not qualify for sale-leaseback accounting. As a result, the 
transaction is being accounted for as a financing. For this transaction, Duke 
Energy Carolinas will continue to record the real estate on the Consolidated 
Balance Sheets within Property, Plant and Equipment as if it were the legal 
owner and will continue to recognize depreciation expense over the estimated 
useful life. In addition, a liability will be recorded for the failed sale-leaseback 
obligation within Long-Term Debt on the Consolidated Balance Sheets, with the 

The following table presents the components of lease expense.

monthly lease payments commencing after the construction phase being split 
between interest expense and principal pay down of the debt.

Duke Energy operates various renewable energy projects and sells 
the generated output to utilities, electric cooperatives, municipalities and 
commercial and industrial customers through long-term PPAs. In certain 
situations, these PPAs and the associated renewable energy projects qualify 
as operating leases. Rental income from these leases is accounted for as 
Nonregulated electric and other revenues in the Consolidated Statements 
of Operations. There are no minimum lease payments as all payments are 
contingent based on actual electricity generated by the renewable energy 
projects. Contingent lease payments were $264 million, $268 million and 
$262 million for the years ended December 31, 2019, 2018, and 2017, 
respectively. Renewable energy projects owned by Duke Energy and accounted 
for as operating leases had a cost basis of $3,349 million and $3,358 million 
and accumulated depreciation of $721 million and $602 million at December 
31, 2019, and 2018, respectively. These assets are principally classified as 
nonregulated electric generation and transmission assets.

Piedmont has an agreement with Duke Energy Carolinas for the 
construction and transportation of natural gas pipelines to supply its natural 
gas plant needs. Piedmont accounts for this pipeline lateral contract as a lessor 
and sales-type lease since the present value of the sum of the lease payments 
equals the fair value of the asset. As of December 31, 2019, the pipeline lateral 
assets owned by Piedmont had a current net investment basis of $4 million and 
a long-term net investment basis of $70 million. These assets are classified 
in Other, within Current Assets and Other Noncurrent Assets, respectively, on 
Piedmont’s Consolidated Balance Sheets. Duke Energy Carolinas accounts for 
the contract as a finance lease. The activity for this contract is eliminated in 
consolidation at Duke Energy.

(a)  The discount rate is calculated using the rate implicit in a lease if it is readily determinable. Generally, the rate used by the lessor is not provided to Duke Energy and in these cases the incremental borrowing rate is used. Duke 
Energy will typically use its fully collateralized incremental borrowing rate as of the commencement date to calculate and record the lease. The incremental borrowing rate is influenced by the lessee’s credit rating and lease 
term and as such may differ for individual leases, embedded leases or portfolios of leased assets.

The Duke Energy Registrants have the ability under certain debt facilities to call and repay the obligation prior to its scheduled maturity. Therefore, the actual 

timing of future cash repayments could be materially different than as presented above.

Short-Term Obligations Classified as Long-Term Debt

Tax-exempt bonds that may be put to the Duke Energy Registrants at the option of the holder and certain commercial paper issuances and money pool borrowings 

are classified as Long-Term Debt on the Consolidated Balance Sheets. These tax-exempt bonds, commercial paper issuances and money pool borrowings, which are 
short-term obligations by nature, are classified as long-term due to Duke Energy’s intent and ability to utilize such borrowings as long-term financing. As Duke Energy’s 
Master Credit Facility and other bilateral letter of credit agreements have non-cancelable terms in excess of one year as of the balance sheet date, Duke Energy has the 
ability to refinance these short-term obligations on a long-term basis. The following tables show short-term obligations classified as long-term debt.

Available Credit Facilities

In March 2019, Duke Energy amended its existing $8 billion Master 
Credit Facility to extend the termination date to March 2024. The Duke Energy 
Registrants, excluding Progress Energy, have borrowing capacity under the 
Master Credit Facility up to a specified sublimit for each borrower. Duke Energy 
has the unilateral ability at any time to increase or decrease the borrowing 
sublimits of each borrower, subject to a maximum sublimit for each borrower. 

The amount available under the Master Credit Facility has been reduced 
to backstop issuances of commercial paper, certain letters of credit and 
variable-rate demand tax-exempt bonds that may be put to the Duke Energy 
Registrants at the option of the holder. Duke Energy Carolinas and Duke Energy 
Progress are also required to each maintain $250 million of available capacity 
under the Master Credit Facility as security to meet obligations under plea 
agreements reached with the U.S. Department of Justice in 2015 related to 
violations at North Carolina facilities with ash basins.

The table below includes the current borrowing sublimits and available capacity under these credit facilities.

Three-Year Revolving Credit Facility

Duke Energy (Parent) has a $1 billion revolving credit facility. The facility 

had an initial termination date of June 2020, but in May 2019, Duke Energy 
extended the termination date of the facility to May 2022. Borrowings under this 
facility will be used for general corporate purposes. As of December 31, 2019, 
$500 million has been drawn under this facility. This balance is classified as 
Long-term debt on Duke Energy’s Consolidated Balance Sheets. Any undrawn 
commitments can be drawn, and borrowings can be prepaid, at any time 
throughout the term of the facility. The terms and conditions of the facility are 
generally consistent with those governing Duke Energy’s Master Credit Facility.

Duke Energy Progress Term Loan Facility

In December 2018, Duke Energy Progress entered into a two-year term 

loan facility with commitments totaling $700 million. Borrowings under the 
facility were used to pay storm-related costs, pay down commercial paper 
and to partially finance an upcoming bond maturity. As of December 31, 2019, 
the entire $700 million has been drawn under the term loan. This balance is 
classified as Current maturities of long-term debt on Duke Energy Progress’ 
Consolidated Balance Sheets.

Piedmont Term Loan Facility

obligations of Duke Energy and are reflected as Notes payable and commercial 
paper on Duke Energy’s Consolidated Balance Sheets.

Money Pool

The Subsidiary Registrants, excluding Progress Energy, are eligible to 
receive support for their short-term borrowing needs through participation 
with Duke Energy and certain of its subsidiaries in a money pool arrangement. 
Under this arrangement, those companies with short-term funds may provide 
short-term loans to affiliates participating in this arrangement. The money 
pool is structured such that the Subsidiary Registrants, excluding Progress 
Energy, separately manage their cash needs and working capital requirements. 
Accordingly, there is no net settlement of receivables and payables between 
money pool participants. Duke Energy (Parent), may loan funds to its 
participating subsidiaries, but may not borrow funds through the money pool. 
Accordingly, as the money pool activity is between Duke Energy and its wholly 
owned subsidiaries, all money pool balances are eliminated within Duke 
Energy’s Consolidated Balance Sheets.

Money pool receivable balances are reflected within Notes receivable 
from affiliated companies on the Subsidiary Registrants’ Consolidated Balance 
Sheets. Money pool payable balances are reflected within either Notes payable 
to affiliated companies or Long-Term Debt Payable to Affiliated Companies on 
the Subsidiary Registrants’ Consolidated Balance Sheets.

In May 2019, the $350 million Piedmont term loan was paid off in full with 

proceeds from the $600 million Piedmont debt offering.

Restrictive Debt Covenants

Other Debt Matters

In September 2019, Duke Energy filed a Form S-3 with the SEC. Under 

this Form S-3, which is uncapped, the Duke Energy Registrants, excluding 
Progress Energy, may issue debt and other securities in the future at amounts, 
prices and with terms to be determined at the time of future offerings. The 
registration statement was filed to replace a similar prior filing upon expiration 
of its three-year term and also allows for the issuance of common and preferred 
stock by Duke Energy. The expired Form S-3 was amended in March 2019, to 
allow Duke Energy to issue preferred stock.

Duke Energy has an effective Form S-3 with the SEC to sell up to $3 billion 

of variable denomination floating-rate demand notes, called PremierNotes. 
The Form S-3 states that no more than $1.5 billion of the notes will be 
outstanding at any particular time. The notes are offered on a continuous basis 
and bear interest at a floating rate per annum determined by the Duke Energy 
PremierNotes Committee, or its designee, on a weekly basis. The interest rate 
payable on notes held by an investor may vary based on the principal amount 
of the investment. The notes have no stated maturity date, are non-transferable 
and may be redeemed in whole or in part by Duke Energy or at the investor’s 
option at any time. The balance as of December 31, 2019, and 2018, was 
$1,049 million and $1,010 million, respectively. The notes are short-term debt 

8.  GUARANTEES AND INDEMNIFICATIONS

The Duke Energy Registrants’ debt and credit agreements contain various 
financial and other covenants. Duke Energy’s Master Credit Facility contains a 
covenant requiring the debt-to-total capitalization ratio not to exceed 65% for 
each borrower, excluding Piedmont, and 70% for Piedmont. Failure to meet those 
covenants beyond applicable grace periods could result in accelerated due dates 
and/or termination of the agreements. As of December 31, 2019, each of the 
Duke Energy Registrants was in compliance with all covenants related to their 
debt agreements. In addition, some credit agreements may allow for acceleration 
of payments or termination of the agreements due to nonpayment, or acceleration 
of other significant indebtedness of the borrower or some of its subsidiaries. None 
of the debt or credit agreements contain material adverse change clauses.

Other Loans

As of December 31, 2019, and 2018, Duke Energy had loans outstanding 
of $777 million, including $36 million at Duke Energy Progress and $741 million, 
including $37 million at Duke Energy Progress, respectively, against the cash 
surrender value of life insurance policies it owns on the lives of its executives. 
The amounts outstanding were carried as a reduction of the related cash 
surrender value that is included in Other within Other Noncurrent Assets on the 
Consolidated Balance Sheets.

Duke Energy has various financial and performance guarantees and 
indemnifications with non-consolidated entities, which are issued in the normal 
course of business. As discussed below, these contracts include performance 
guarantees, standby letters of credit, debt guarantees and indemnifications. 
Duke Energy enters into these arrangements to facilitate commercial 
transactions with third parties by enhancing the value of the transaction to the 
third party. At December 31, 2019, Duke Energy does not believe conditions are 
likely for significant performance under these guarantees. To the extent liabilities 

are incurred as a result of the activities covered by the guarantees, such 
liabilities are included on the accompanying Consolidated Balance Sheets.

On January 2, 2007, Duke Energy completed the spin-off of its previously 

wholly-owned natural gas businesses to shareholders. Guarantees issued by 
Duke Energy or its affiliates, or assigned to Duke Energy prior to the spin-off, 
remained with Duke Energy subsequent to the spin-off. Guarantees issued 
by Spectra Capital or its affiliates prior to the spin-off remained with Spectra 
Capital subsequent to the spin-off, except for guarantees that were later

Duke Energy has indemnified Spectra Capital against 
any losses incurred under certain of the guarantee obligations that remain 
with Spectra Capital. At December 31, 2019, the maximum potential amount 
of future payments associated with these guarantees were $65 million, the 
majority of which expires by 2028.

In October 2017, ACP executed a $3.4 billion revolving credit facility with 
a stated maturity date of October 2021. Duke Energy entered into a guarantee 
agreement to support its share of the ACP revolving credit facility. Duke Energy’s 
maximum exposure to loss under the terms of the guarantee is $827 million 
as of December 31, 2019. This amount represents 47% of the outstanding 
borrowings under the credit facility.

In addition to the Spectra Capital and ACP revolving credit facility 
guarantees above, Duke Energy has issued performance guarantees to 
customers and other third parties that guarantee the payment and performance 
of other parties, including certain non-wholly owned entities, as well as 
guarantees of debt of certain non-consolidated entities. If such entities were 
to default on payments or performance, Duke Energy would be required under 
the guarantees to make payments on the obligations of these entities. The 
maximum potential amount of future payments required under these guarantees 
as of December 31, 2019, was $128 million, of which, $114 million expire 

between 2020 and 2030, with the remaining performance guarantees having 
no contractual expiration. Additionally, certain guarantees have uncapped 
maximum potential payments; however, Duke Energy does not believe these 
guarantees will have a material effect on its results of operations, cash flows or 
financial position.

Duke Energy uses bank-issued standby letters of credit to secure the 
performance of wholly owned and non-wholly owned entities to a third party 
or customer. Under these arrangements, Duke Energy has payment obligations 
to the issuing bank that are triggered by a draw by the third party or customer 
due to the failure of the wholly owned or non-wholly owned entity to perform 
according to the terms of its underlying contract. At December 31, 2019, Duke 
Energy had issued a total of $634 million in letters of credit, which expire 
between 2020 and 2022. The unused amount under these letters of credit 
was $81 million.

Duke Energy recognized $23 million as of December 31, 2019, and 2018, 

primarily in Other within Other Noncurrent Liabilities on the Consolidated 
Balance Sheets, for the guarantees discussed above. As current estimates 
change, additional losses related to guarantees and indemnifications to 
third parties, which could be material, may be recorded by the Duke Energy 
Registrants in the future.

9.  JOINT OWNERSHIP OF GENERATING AND TRANSMISSION FACILITIES

The Duke Energy Registrants maintain ownership interests in certain 

jointly owned generating and transmission facilities. The Duke Energy 
Registrants are entitled to a share of the generating capacity and output of 
each unit equal to their respective ownership interests. The Duke Energy 
Registrants pay their ownership share of additional construction costs, fuel 

inventory purchases and operating expenses. The Duke Energy Registrants 
share of revenues and operating costs of the jointly owned facilities is 
included within the corresponding line in the Consolidated Statements of 
Operations. Each participant in the jointly owned facilities must provide its 
own financing.

The following table presents the Duke Energy Registrants’ interest of jointly owned plant or facilities and amounts included on the Consolidated Balance Sheets. 

All facilities are operated by the Duke Energy Registrants and are included in the Electric Utilities and Infrastructure segment.

10.  ASSET RETIREMENT OBLIGATIONS

Duke Energy records an ARO when it has a legal obligation to incur 
retirement costs associated with the retirement of a long-lived asset and the 
obligation can be reasonably estimated. Certain assets of the Duke Energy 
Registrants have an indeterminate life, such as transmission and distribution 
facilities, and thus the fair value of the retirement obligation is not reasonably 
estimable. A liability for these AROs will be recorded when a fair value is 
determinable.

The Duke Energy Registrants’ regulated operations accrue costs of 

removal for property that does not have an associated legal retirement 
obligation based on regulatory orders from state commissions. These costs 
of removal are recorded as a regulatory liability in accordance with regulatory 
accounting treatment. The Duke Energy Registrants do not accrue the estimated 
cost of removal for any nonregulated assets. See Note 4 for the estimated cost 
of removal for assets without an associated legal retirement obligation, which 
are included in Regulatory liabilities on the Consolidated Balance Sheets.

Nuclear Decommissioning Liability

AROs related to nuclear decommissioning are based on site-specific 

cost studies. The NCUC, PSCSC and FPSC require updated cost estimates for 
decommissioning nuclear plants every five years.

The following table summarizes information about the most recent 
site-specific nuclear decommissioning cost studies. Decommissioning costs 
are stated in 2018 or 2019 dollars, depending on the year of the cost study, 
and include costs to decommission plant components not subject to radioactive 
contamination.

(b)  Decommissioning cost for Duke Energy Carolinas reflects its ownership interest in jointly owned reactors. 
Other joint owners are responsible for decommissioning costs related to their interest in the reactors.

(c)  Duke Energy Carolinas’ site-specific nuclear decommissioning cost study completed in 2018 was filed 
with the NCUC and PSCSC in 2019. A new funding study was also completed and filed with the NCUC 
and PSCSC in 2019.

(d)  Duke Energy Progress’ site-specific nuclear decommissioning cost study completed in 2019 is expected 
to be filed with the NCUC and PSCSC during the first quarter 2020. Duke Energy Progress will also 
complete a new funding study, which will be completed and filed with the NCUC and PSCSC in July 2020.

(e)  During 2019, Duke Energy Florida reached an agreement to transfer decommissioning work for Crystal 
River Unit 3 to a third party. The agreement requires regulatory approval from the NRC and the FPSC. 
See Note 4 for more information.

Nuclear Decommissioning Trust Funds

Duke Energy Carolinas, Duke Energy Progress and Duke Energy Florida 
each maintain NDTFs that are intended to pay for the decommissioning costs 
of their respective nuclear power plants. The NDTF investments are managed 
and invested in accordance with applicable requirements of various regulatory 
bodies including the NRC, FERC, NCUC, PSCSC, FPSC and the IRS.

Use of the NDTF investments is restricted to nuclear decommissioning 

activities including license termination, spent fuel and site restoration. 
The license termination and spent fuel obligations relate to contaminated 
decommissioning and are recorded as AROs. The site restoration obligation 
relates to non-contaminated decommissioning and is recorded to cost of 
removal within Regulatory liabilities on the Consolidated Balance Sheets.

150

The following table presents the fair value of NDTF assets legally restricted 

for purposes of settling AROs associated with nuclear decommissioning. Duke 
Energy Florida is actively decommissioning Crystal River Unit 3 and was granted 
an exemption from the NRC, which allows for use of the NDTF for all aspects 
of nuclear decommissioning. The entire balance of Duke Energy Florida’s NDTF 
may be applied toward license termination, spent fuel and site restoration costs 
incurred to decommission Crystal River Unit 3 and is excluded from the table 
below. See Note 17 for additional information related to the fair value of the 
Duke Energy Registrants’ NDTFs.

The NRC has acknowledged permanent cessation of operation 

and permanent removal of fuel from the reactor vessel at Crystal River 
Unit 3. Therefore, the license no longer authorizes operation of the reactor. 
In 2019, Duke Energy Florida entered into an agreement for the accelerated 
decommissioning of Crystal River Unit 3. The agreement is subject to the 
approval of the NRC and FPSC. See Note 4 for more information.

The Duke Energy Registrants are subject to state and federal regulations 

covering the closure of coal ash impoundments, including the EPA CCR rule 
and the Coal Ash Act, and other agreements. AROs recorded on the Duke 
Energy Registrants’ Consolidated Balance Sheets include the legal obligation for 
closure of coal ash basins and the disposal of related ash as a result of these 
regulations and agreements.

The ARO amount recorded on the Consolidated Balance Sheets is based 

upon estimated closure costs for impacted ash impoundments. The amount 
recorded represents the discounted cash flows for estimated closure costs 
based upon specific closure plans. Actual costs to be incurred will be dependent 
upon factors that vary from site to site. The most significant factors are the 
method and time frame of closure at the individual sites. Closure methods 
considered include removing the water from ash basins, consolidating material 
as necessary and capping the ash with a synthetic barrier, excavating and 
relocating the ash to a lined structural fill or lined landfill or recycling the ash for 

concrete or some other beneficial use. The ultimate method and timetable for 
closure will be in compliance with standards set by federal and state regulations 
and other agreements. The ARO amount will be adjusted as additional 
information is gained through the closure and post-closure process, including 
acceptance and approval of compliance approaches, which may change 
management assumptions, and may result in a material change to the balance. 
See ARO Liability Rollforward section below for information on revisions made to 
the coal ash liability during 2019 and 2018.

Asset retirement costs associated with the AROs for operating plants and 
retired plants are included in Net property, plant and equipment and Regulatory 
assets, respectively, on the Consolidated Balance Sheets. See Note 4 for 
additional information on Regulatory assets related to AROs.

Cost recovery for future expenditures will be pursued through the normal 

ratemaking process with federal and state utility commissions, which permit 
recovery of necessary and prudently incurred costs associated with Duke 
Energy’s regulated operations. See Note 4 for additional information on recovery 
of coal ash costs.

Energy Indiana, respectively, primarily within Plant – Regulated. The Progress Energy, Duke Energy Progress and Duke Energy Florida amounts are net of $143 million, $17 million and $126 million, respectively, of accumulated 
amortization of finance leases.
Includes $1,807 million, $1,082 million, $725 million and $725 million of accumulated amortization of nuclear fuel at Duke Energy, Duke Energy Carolinas, Progress Energy and Duke Energy Progress, respectively.
Includes accumulated amortization of finance leases of $6 million, $13 million and $3 million at Duke Energy, Duke Energy Carolinas and Duke Energy Indiana, respectively.
Includes accumulated amortization of finance leases of $20 million at Duke Energy.
Includes gross property, plant and equipment cost of consolidated VIEs of $5,747 million and accumulated depreciation of consolidated VIEs of $1,041 million at Duke Energy.

During the year ended December 31, 2019, Duke Energy evaluated 
recoverability of the wind and solar generation assets included in the minority 
interest sale as a result of the portfolio fair value of consideration received being 
less than the carrying value of the assets and determined the assets were all 
recoverable. Additionally, in 2019, Duke Energy evaluated recoverability of its 
renewable merchant plants principally located in the Electric Reliability Council 

of Texas West market due to declining market pricing and declining long-term 
forecasted energy prices, primarily driven by lower forecasted natural gas 
prices. Duke Energy determined that the assets were not impaired because the 
carrying value of $160 million approximates the aggregate estimated future 
cash flows. A continued decline in energy market pricing would likely result in a 
future impairment.

Florida, Duke Energy Ohio and Duke Energy Indiana, respectively, primarily within Plant – Regulated. The Progress Energy, Duke Energy Progress and Duke Energy Florida amounts are net of $131 million, $14 million and $117 
million, respectively, of accumulated amortization of finance leases.
Includes $1,947 million, $1,087 million, $860 million and $860 million of accumulated amortization of nuclear fuel at Duke Energy, Duke Energy Carolinas, Progress Energy and Duke Energy Progress, respectively.
Includes accumulated amortization of finance leases of $61 million, $12 million, $20 million and $10 million at Duke Energy, Duke Energy Carolinas, Duke Energy Ohio and Duke Energy Indiana, respectively.
Includes gross property, plant and equipment cost of consolidated VIEs of $4,007 million and accumulated depreciation of consolidated VIEs of $698 million at Duke Energy.

During the year ended December 31, 2017, Duke Energy recorded a 

pretax impairment charge of $69 million on a wholly owned non-contracted 
wind project. The impairment was recorded within Impairment charges on Duke 
Energy’s Consolidated Statements of Operations. $58 million of the impairment 
related to property, plant and equipment and $11 million of the impairment 
related to a net intangible asset. The charge represents the excess carrying 
value over the estimated fair value of the project, which was based on a Level 3 

Fair Value measurement that was determined from the income approach using 
discounted cash flows. The impairment was primarily due to the non-contracted 
wind project being located in a market that has experienced continued declining 
market pricing during 2017 and declining long-term forecasted energy and 
capacity prices, driven by low natural gas prices, additional renewable 
generation placed in service and lack of significant load growth.

(a)  Duke Energy evaluated the recoverability of goodwill during 2018 and 2017 and recorded impairment 
charges of $93 million and $29 million, respectively, related to the Commercial Renewables reporting 
unit included in Impairment charges on Duke Energy’s Consolidated Statements of Operations. The fair 
value of the reporting unit was determined based on the income approach and market approach in 2018 
and 2017, respectively. See “Goodwill Impairment Testing” below for the results of the 2019 goodwill 
impairment test.

Goodwill Impairment Testing

Duke Energy, Progress Energy, Duke Energy Ohio and Piedmont are required 

to perform an annual goodwill impairment test as of the same date each year 
and, accordingly, perform their annual impairment testing of goodwill as of 
August 31. Duke Energy, Progress Energy, Duke Energy Ohio and Piedmont update 
their test between annual tests if events or circumstances occur that would 
more likely than not reduce the fair value of a reporting unit below its carrying 
value. As the fair value for Duke Energy, Progress Energy, Duke Energy Ohio and 
Piedmont exceeded their respective carrying values at the date of the annual 
impairment analysis, no goodwill impairment charges were recorded in 2019.

Intangible Assets

During the years ended December 31, 2019, 2018 and 2017, Duke Energy 
received distributions from equity investments of $55 million, $108 million and 
$13 million, respectively, which are included in Other assets within Cash Flows 
from Operating Activities on the Consolidated Statements of Cash Flows. During 
the years ended December 31, 2019, 2018 and 2017, Duke Energy received 
distributions from equity investments of $11 million, $137 million and $281 million, 
respectively, which are included in Return of investment capital within Cash Flows 
from Investing Activities on the Consolidated Statements of Cash Flows.

In October 2017, Duke Energy entered into a guarantee agreement to support 

its share of the ACP revolving credit facility. See Note 8 for additional information. 
As a result of the financing, ACP returned capital of $265 million to Duke Energy.
During 2018 and 2019, ACP received several adverse court rulings as 
described in Note 4. As a result, Duke Energy evaluated this investment for 
impairment and determined that fair value approximated carrying value and 
therefore no impairment was necessary.

For regulatory matters and other information on the ACP, Sabal Trail and 

During the years ended December 31, 2019, 2018 and 2017, Piedmont 

Constitution investments, see Notes 4 and 18.

received distributions from equity investments of $1 million, $1 million and 
$4 million, respectively, which are included in Other assets within Cash Flows 
from Operating Activities and $4 million, $3 million and $2 million, respectively, 
which are included within Cash Flows from Investing Activities on the 
Consolidated Statements of Cash Flows.

Significant investments in affiliates accounted for under the equity 

method are discussed below.

Electric Utilities and Infrastructure

Duke Energy owns a 50% interest in DATC and in Pioneer, which build, 

own and operate electric transmission facilities in North America.

Commercial Renewables

DS Cornerstone, LLC, which owns wind farm projects in the U.S. was part 

of a sale of minority interest in a certain portion of renewable assets to John 
Hancock in 2019. See Note 2 for more information on the sale. Prior to the sale, 
Duke Energy had a 50% interest in DS Cornerstone, LLC. After the sale, Duke 
Energy has a 26% interest in the investment.

In 2019, Duke Energy acquired a majority ownership in a portfolio of 
distributed fuel cell projects from Bloom Energy Corporation. Duke Energy is 
not the primary beneficiary of the assets within the portfolio and does not 
consolidate the assets in the portfolio.

Duke Energy recorded OTTIs of the Constitution investment within 
Equity in earnings of unconsolidated affiliates on Duke Energy’s Consolidated 
Statements of Operations of $25 million and $55 million for the years ended 
December 31, 2019, and 2018, respectively. The current year charge resulted 
in the full write-down of Duke Energy’s investment in Constitution. The 
impairments were primarily due to the continued delay in resolving project 
uncertainty through the courts and regulatory bodies, as well as recent pricing 
concerns between the customers and owners. For additional information on 
the Constitution investment, see Note 4.

Other

Duke Energy owns a 17.5% indirect interest in NMC, which owns and 
operates a methanol and MTBE business in Jubail, Saudi Arabia. Duke Energy’s 
economic ownership interest decreased from 25% to 17.5% with the successful 
startup of NMC’s polyacetal production facility in 2017. Duke Energy retains 
25% of the board representation and voting rights of NMC.

(a)  The Subsidiary Registrants are charged their proportionate share of corporate governance and other shared 
services costs, primarily related to human resources, employee benefits, information technology, legal and 
accounting fees, as well as other third-party costs. These amounts are primarily recorded in Operation, 
maintenance and other on the Consolidated Statements of Operations and Comprehensive Income.
(b)  The Subsidiary Registrants incur expenses related to certain indemnification coverages through Bison, 
Duke Energy’s wholly owned captive insurance subsidiary. These expenses are recorded in Operation, 
maintenance and other on the Consolidated Statements of Operations and Comprehensive Income.
(c)  Duke Energy Carolinas and Duke Energy Progress participate in a JDA, which allows the collective dispatch 
of power plants between the service territories to reduce customer rates. Revenues from the sale of power 
and expenses from the purchase of power pursuant to the JDA are recorded in Operating Revenues and 
Fuel used in electric generation and purchased power, respectively, on the Consolidated Statements of 
Operations and Comprehensive Income.

(d)  Piedmont provides long-term natural gas delivery service to certain Duke Energy Carolinas and Duke 

Energy Progress natural gas-fired generation facilities. Piedmont records the sales in Operating Revenues, 
and Duke Energy Carolinas and Duke Energy Progress record the related purchases as a component of 
Fuel used in electric generation and purchased power on their respective Consolidated Statements of 
Operations and Comprehensive Income. These intercompany revenues and expenses are eliminated in 
consolidation.

(e)  Piedmont has related party transactions as a customer of its equity method investments in Pine Needle, 

Hardy Storage, and Cardinal natural gas storage and transportation facilities. These expenses are included 
in Cost of natural gas on Piedmont’s Consolidated Statements of Operations and Comprehensive Income.

In addition to the amounts presented above, the Subsidiary Registrants 
have other affiliate transactions, including rental of office space, participation 
in a money pool arrangement, other operational transactions and their 
proportionate share of certain charged expenses. See Note 7 for more 
information regarding money pool. These transactions of the Subsidiary 
Registrants are incurred in the ordinary course of business and are eliminated 
in consolidation.

As discussed in Note 18, certain trade receivables have been sold by 
Duke Energy Ohio and Duke Energy Indiana to CRC, an affiliate formed by a 
subsidiary of Duke Energy. The proceeds obtained from the sales of receivables 
are largely cash but do include a subordinated note from CRC for a portion of the 
purchase price.

Duke Energy and the Subsidiary Registrants file a consolidated federal income tax return and other state and jurisdictional returns. The Subsidiary Registrants have a 
tax sharing agreement with Duke Energy for the allocation of consolidated tax liabilities and benefits. Income taxes recorded represent amounts the Subsidiary Registrants 
would incur as separate C-Corporations. The following table includes the balance of intercompany income tax receivables and payables for the Subsidiary Registrants.

DERIVATIVES AND HEDGING

The Duke Energy Registrants use commodity and interest rate contracts 

to manage commodity price risk and interest rate risk. The primary use of 
commodity derivatives is to hedge the generation portfolio against changes in 
the prices of electricity and natural gas. Piedmont enters into natural gas supply 
contracts to provide diversification, reliability and natural gas cost benefits to 
its customers. Interest rate derivatives are used to manage interest rate risk 
associated with borrowings.

All derivative instruments not identified as NPNS are recorded at fair 

value as assets or liabilities on the Consolidated Balance Sheets. Cash 
collateral related to derivative instruments executed under master netting 
arrangements is offset against the collateralized derivatives on the Consolidated 
Balance Sheets. The cash impacts of settled derivatives are recorded as 
operating activities on the Consolidated Statements of Cash Flows.

Cash Flow Hedges

For a derivative designated as hedging the exposure to variable cash 
flows of a future transaction, referred to as a cash flow hedge, the effective 
portion of the derivative’s gain or loss is initially reported as a component of 
other comprehensive income and subsequently reclassified into earnings once 
the future transaction impacts earnings. Amounts for interest rate contracts are 
reclassified to earnings as interest expense over the term of the related debt. 
Gains and losses reclassified out of AOCI for the years ended December 31, 
2019, 2018 and 2017 were not material. Duke Energy’s interest rate derivatives 
designated as hedges include interest rate swaps used to hedge existing debt 
within the Commercial Renewables business and forward-starting interest rate 
swaps not accounted for under regulatory accounting.

INTEREST RATE RISK

Undesignated Contracts

The Duke Energy Registrants are exposed to changes in interest rates 

as a result of their issuance or anticipated issuance of variable-rate and 
fixed-rate debt and commercial paper. Interest rate risk is managed by limiting 
variable-rate exposures to a percentage of total debt and by monitoring changes 
in interest rates. To manage risk associated with changes in interest rates, the 
Duke Energy Registrants may enter into interest rate swaps, U.S. Treasury lock 
agreements and other financial contracts. In anticipation of certain fixed-rate 
debt issuances, a series of forward-starting interest rate swaps or Treasury 
locks may be executed to lock in components of current market interest rates. 
These instruments are later terminated prior to or upon the issuance of the 
corresponding debt.

Undesignated contracts primarily include contracts not designated as a 

hedge because they are accounted for under regulatory accounting or contracts 
that do not qualify for hedge accounting.

Duke Energy’s interest rate swaps for its regulated operations employ 
regulatory accounting. With regulatory accounting, the mark-to-market gains or 
losses on the swaps are deferred as regulatory liabilities or regulatory assets, 
respectively. Regulatory assets and liabilities are amortized consistent with the 
treatment of the related costs in the ratemaking process. The accrual of interest 
on the swaps is recorded as Interest Expense on the Duke Energy Registrant’s 
Consolidated Statements of Operations and Comprehensive Income.

The following tables show notional amounts of outstanding derivatives related to interest rate risk.

(a)  Duke Energy includes amounts related to consolidated VIEs of $693 million in cash flow hedges as of December 31, 2019, and $422 million in cash flow hedges and $194 million in undesignated contracts as of December 31, 2018.

COMMODITY PRICE RISK

The Duke Energy Registrants are exposed to the impact of changes in 
the prices of electricity purchased and sold in bulk power markets and coal 
and natural gas purchases, including Piedmont’s natural gas supply contracts. 
Exposure to commodity price risk is influenced by a number of factors including 
the term of contracts, the liquidity of markets and delivery locations. For 
the Subsidiary Registrants, bulk power electricity and coal and natural gas 

purchases flow through fuel adjustment clauses, formula based contracts or 
other cost sharing mechanisms. Differences between the costs included in rates 
and the incurred costs, including undesignated derivative contracts, are largely 
deferred as regulatory assets or regulatory liabilities. Piedmont policies allow for 
the use of financial instruments to hedge commodity price risks. The strategy 
and objective of these hedging programs are to use the financial instruments to 
reduce gas cost volatility for customers.

U.S. EQUITY SECURITIES RISK 

In May 2019, Duke Energy Florida entered into a Decommissioning 
Services Agreement for the accelerated decommissioning of Crystal River Unit 3 
with ADP CR3, LLC and ADP SF1, LLC. See Note 4 for additional information 
on the accelerated decommissioning. Duke Energy Florida executed U.S. 
equity option collars within the NDTF in May 2019 to preserve the U.S. equity 
portfolio value in the Duke Energy Florida NDTF in the event the accelerated 
decommissioning is approved. These option collars were executed as a 
purchase of a put option and the sale of a call option on certain U.S. equity 

index funds. The put and call options create a collar to guarantee a minimum 
and maximum investment value for the Duke Energy Florida NDTF U.S. equity 
portfolio. The put and call options were entered into at zero-cost, with the price 
to purchase the puts offset entirely by the funds received to sell the calls. As 
of December 31, 2019, the aggregate notional amount of both the put and call 
options was 305,000 units in U.S. equity security index funds. The options 
are not designated as hedging instruments. Substantially all of Duke Energy 
Florida’s NDTF qualifies for regulatory accounting. With regulatory accounting, 
the mark-to-market gains or losses on the options are deferred as regulatory 
liabilities or regulatory assets, respectively.

Certain derivative contracts contain objective credit contingent features. These features include the requirement to post cash collateral or letters of credit if 
specific events occur, such as a credit rating downgrade below investment grade. The following tables show information with respect to derivative contracts that are 
in a net liability position and contain objective credit-risk-related payment provisions.

INVESTMENTS IN DEBT AND EQUITY SECURITIES

Duke Energy’s investments in debt and equity securities are primarily 

comprised of investments held in (i) the NDTF at Duke Energy Carolinas, Duke 
Energy Progress and Duke Energy Florida, (ii) the grantor trusts at Duke Energy 
Progress, Duke Energy Florida and Duke Energy Indiana related to OPEB plans 
and (iii) Bison. The Duke Energy Registrants classify investments in debt 
securities as AFS and investments in equity securities as FV-NI.

For investments in debt securities classified as AFS, the unrealized gains 
and losses are included in other comprehensive income until realized, at which 

time, they are reported though net income. For investments in equity securities 
classified as FV-NI, both realized and unrealized gains and losses are reported 
through net income. Substantially all of Duke Energy’s investments in debt 
and equity securities qualify for regulatory accounting, and accordingly, all 
associated realized and unrealized gains and losses on these investments are 
deferred as a regulatory asset or liability.

Duke Energy classifies the majority of investments in debt and equity 

securities as long term, unless otherwise noted.

Other AFS Securities

The investments within the Investment Trusts are managed by 
independent investment managers with discretion to buy, sell and invest 
pursuant to the objectives set forth by the trust agreements. The Duke Energy 
Registrants have limited oversight of the day-to-day management of these 
investments. As a result, the ability to hold investments in unrealized loss 
positions is outside the control of the Duke Energy Registrants. Accordingly, all 
unrealized losses associated with debt securities within the Investment Trusts 
are considered OTTIs and are recognized immediately and deferred to regulatory 
accounts where appropriate.

Unrealized gains and losses on all other AFS securities are included in 

other comprehensive income until realized, unless it is determined the carrying 
value of an investment is other-than-temporarily impaired. The Duke Energy 
Registrants analyze all investment holdings each reporting period to determine 
whether a decline in fair value should be considered other-than-temporary. If 
an OTTI exists, the unrealized credit loss is included in earnings. There were no 
material credit losses as of December 31, 2019, and 2018.

Other Investments amounts are recorded in Other within Other Noncurrent 

Assets on the Consolidated Balance Sheets.

FAIR VALUE MEASUREMENTS

Fair value is the exchange price to sell an asset or transfer a liability in 
an orderly transaction between market participants at the measurement date. 
The fair value definition focuses on an exit price versus the acquisition cost. 
Fair value measurements use market data or assumptions market participants 
would use in pricing the asset or liability, including assumptions about risk and 
the risks inherent in the inputs to the valuation technique. These inputs may 
be readily observable, corroborated by market data, or generally unobservable. 
Valuation techniques maximize the use of observable inputs and minimize use 
of unobservable inputs. A midmarket pricing convention (the midpoint price 
between bid and ask prices) is permitted for use as a practical expedient.

Fair value measurements are classified in three levels based on the fair 

value hierarchy as defined by GAAP. Certain investments are not categorized 
within the fair value hierarchy. These investments are measured at fair value 
using the NAV per share practical expedient. The net asset value is derived 
based on the investment cost, less any impairment, plus or minus changes 
resulting from observable price changes for an identical or similar investment of 
the same issuer.

Fair value accounting guidance permits entities to elect to measure 
certain financial instruments that are not required to be accounted for at fair 
value, such as equity method investments or the company’s own debt, at fair 
value. The Duke Energy Registrants have not elected to record any of these 
items at fair value.

Valuation methods of the primary fair value measurements disclosed 

below are as follows.

Investments in equity securities

The majority of investments in equity securities are valued using Level 
1 measurements. Investments in equity securities are typically valued at the 
closing price in the principal active market as of the last business day of the 
quarter. Principal active markets for equity prices include published exchanges 
such as the NYSE and Nasdaq Stock Market. Foreign equity prices are translated 
from their trading currency using the currency exchange rate in effect at the 
close of the principal active market. There was no after-hours market activity 
that was required to be reflected in the reported fair value measurements.

DUKE ENERGY

Investments in debt securities

Most investments in debt securities are valued using Level 2 
measurements because the valuations use interest rate curves and credit 
spreads applied to the terms of the debt instrument (maturity and coupon 
interest rate) and consider the counterparty credit rating. If the market for a 
particular fixed-income security is relatively inactive or illiquid, the measurement 
is Level 3.

Commodity derivatives

Commodity derivatives with clearinghouses are classified as Level 1. If 

forward price curves are not observable for the full term of the contract and the 
unobservable period had more than an insignificant impact on the valuation, the 
commodity derivative is classified as Level 3. In isolation, increases (decreases) 
in natural gas forward prices result in favorable (unfavorable) fair value 
adjustments for natural gas purchase contracts; and increases (decreases) in 
electricity forward prices result in unfavorable (favorable) fair value adjustments 
for electricity sales contracts. Duke Energy regularly evaluates and validates 
pricing inputs used to estimate the fair value of natural gas commodity contracts 
by a market participant price verification procedure. This procedure provides 
a comparison of internal forward commodity curves to market participant 
generated curves.

Interest rate derivatives

Most over-the-counter interest rate contract derivatives are valued using 

financial models that utilize observable inputs for similar instruments and 
are classified as Level 2. Inputs include forward interest rate curves, notional 
amounts, interest rates and credit quality of the counterparties.

Other fair value considerations

See Note 12 for a discussion of the valuation of goodwill and intangible 

assets.

The following tables provide recorded balances for assets and liabilities measured at fair value on a recurring basis on the Consolidated Balance Sheets. 
Derivative amounts in the tables below for all Duke Energy Registrants exclude cash collateral, which is disclosed in Note 15. See Note 16 for additional information 
related to investments by major security type for the Duke Energy Registrants.

At both December 31, 2019, and December 31, 2018, fair value of cash and cash equivalents, accounts and notes receivable, accounts payable, notes payable 

and commercial paper, and nonrecourse notes payable of VIEs are not materially different from their carrying amounts because of the short-term nature of these 
instruments and/or because the stated rates approximate market rates.

VARIABLE INTEREST ENTITIES 

A VIE is an entity that is evaluated for consolidation using more than 
a simple analysis of voting control. The analysis to determine whether an 
entity is a VIE considers contracts with an entity, credit support for an entity, 
the adequacy of the equity investment of an entity and the relationship of 
voting power to the amount of equity invested in an entity. This analysis is 
performed either upon the creation of a legal entity or upon the occurrence of 
an event requiring reevaluation, such as a significant change in an entity’s 
assets or activities. A qualitative analysis of control determines the party that 
consolidates a VIE. This assessment is based on (i) what party has the power 
to direct the activities of the VIE that most significantly impact its economic 
performance and (ii) what party has rights to receive benefits or is obligated to 
absorb losses that could potentially be significant to the VIE. The analysis of the 
party that consolidates a VIE is a continual reassessment.

CONSOLIDATED VIEs

The obligations of the consolidated VIEs discussed in the following 
paragraphs are nonrecourse to the Duke Energy Registrants. The registrants 
have no requirement to provide liquidity to, purchase assets of or guarantee 
performance of these VIEs unless noted in the following paragraphs.

No financial support was provided to any of the consolidated VIEs during 

the years ended December 31, 2019, 2018, and 2017, or is expected to be 
provided in the future, that was not previously contractually required.

Receivables Financing – DERF/DEPR/DEFR

DERF, DEPR and DEFR are bankruptcy remote, special purpose 

subsidiaries of Duke Energy Carolinas, Duke Energy Progress and Duke Energy 
Florida, respectively. DERF, DEPR and DEFR are wholly owned LLCs with 
separate legal existence from their parent companies, and their assets are not 
generally available to creditors of their parent companies. On a revolving basis, 
DERF, DEPR and DEFR buy certain accounts receivable arising from the sale of 
electricity and related services from their parent companies.

DERF, DEPR and DEFR borrow amounts under credit facilities to buy these 

receivables. Borrowing availability from the credit facilities is limited to the 

Receivables Financing – Credit Facilities

amount of qualified receivables purchased. The sole source of funds to satisfy 
the related debt obligations is cash collections from the receivables. Amounts 
borrowed under the credit facilities are reflected on the Consolidated Balance 
Sheets as Long-Term Debt.

The most significant activity that impacts the economic performance 

of DERF, DEPR and DEFR are the decisions made to manage delinquent 
receivables. Duke Energy Carolinas, Duke Energy Progress and Duke Energy 
Florida are considered the primary beneficiaries and consolidate DERF, DEPR 
and DEFR, respectively, as they make those decisions.

Receivables Financing – CRC

CRC is a bankruptcy remote, special purpose entity indirectly owned by 

Duke Energy. On a revolving basis, CRC buys certain accounts receivable arising 
from the sale of electricity, natural gas and related services from Duke Energy 
Ohio and Duke Energy Indiana. CRC borrows amounts under a credit facility to 
buy the receivables from Duke Energy Ohio and Duke Energy Indiana. Borrowing 
availability from the credit facility is limited to the amount of qualified receivables 
sold to CRC. The sole source of funds to satisfy the related debt obligation is cash 
collections from the receivables. Amounts borrowed under the credit facility are 
reflected on Duke Energy’s Consolidated Balance Sheets as Long-Term Debt.

The proceeds Duke Energy Ohio and Duke Energy Indiana receive from the 
sale of receivables to CRC are approximately 75% cash and 25% in the form of 
a subordinated note from CRC. The subordinated note is a retained interest in the 
receivables sold. Depending on collection experience, additional equity infusions 
to CRC may be required by Duke Energy to maintain a minimum equity balance 
of $3 million.

CRC is considered a VIE because (i) equity capitalization is insufficient to 
support its operations, (ii) power to direct the activities that most significantly 
impact the economic performance of the entity is not held by the equity holder 
and (iii) deficiencies in net worth of CRC are funded by Duke Energy. The most 
significant activities that impact the economic performance of CRC are decisions 
made to manage delinquent receivables. Duke Energy is considered the primary 
beneficiary and consolidates CRC as it makes these decisions. Neither Duke 
Energy Ohio nor Duke Energy Indiana consolidate CRC.

The following table summarizes the amounts and expiration dates of the credit facilities and associated restricted receivables described above.

DEFPF is a bankruptcy remote, wholly owned special purpose subsidiary of Duke Energy Florida. DEFPF was formed in 2016 for the sole purpose of issuing 

nuclear asset-recovery bonds to finance Duke Energy Florida’s unrecovered regulatory asset related to Crystal River Unit 3.

In 2016, DEFPF issued senior secured bonds and used the proceeds to acquire nuclear asset-recovery property from Duke Energy Florida. The nuclear 
asset-recovery property acquired includes the right to impose, bill, collect and adjust a non-bypassable nuclear asset-recovery charge from all Duke Energy Florida 
retail customers until the bonds are paid in full and all financing costs have been recovered. The nuclear asset-recovery bonds are secured by the nuclear 
asset-recovery property and cash collections from the nuclear asset-recovery charges are the sole source of funds to satisfy the debt obligation. The bondholders 
have no recourse to Duke Energy Florida.

DEFPF is considered a VIE primarily because the equity capitalization is insufficient to support its operations. Duke Energy Florida has the power to direct the 

significant activities of the VIE as described above and therefore Duke Energy Florida is considered the primary beneficiary and consolidates DEFPF.

The following table summarizes the impact of DEFPF on Duke Energy Florida’s Consolidated Balance Sheets.

Certain of Duke Energy’s renewable energy facilities are VIEs due to Duke Energy issuing guarantees for debt service and operations and maintenance reserves 

in support of debt financings. Assets are restricted and cannot be pledged as collateral or sold to third parties without prior approval of debt holders. Additionally, 
Duke Energy has VIEs associated with tax equity arrangements entered into with third-party investors in order to finance the cost of renewable assets eligible for 
tax credits. The activities that most significantly impacted the economic performance of these renewable energy facilities were decisions associated with siting, 
negotiating PPAs and EPC agreements, and decisions associated with ongoing operations and maintenance-related activities. Duke Energy is considered the primary 
beneficiary and consolidates the entities as it is responsible for all of these decisions.

(a)  Duke Energy holds a 50% equity interest in Pioneer. As of December 31, 2018, Pioneer was considered a VIE due to having insufficient equity to finance its own activities without subordinated financial support. In October 2019, Pioneer 
closed on a private placement debt offering that gave Pioneer sufficient equity to finance its own activities and, therefore, is no longer considered a VIE. Duke Energy’s investment in Pioneer was $57 million at December 31, 2019.

The Duke Energy Registrants are not aware of any situations where the 

The table below presents Duke Energy’s ownership interest and 

maximum exposure to loss significantly exceeds the carrying values shown 
above except for the PPA with OVEC, which is discussed below, and various 
guarantees, including Duke Energy’s guarantee agreement to support its share 
of the ACP revolving credit facility. Duke Energy’s maximum exposure to loss 
under the terms of the guarantee is $827 million, which represents 47% of the 
outstanding borrowings under the credit facility as of December 31, 2019. For 
more information on various guarantees, refer to Note 8.

Pipeline Investments

Duke Energy has investments in various joint ventures with pipeline 
projects currently under construction. These entities are considered VIEs due to 
having insufficient equity to finance their own activities without subordinated 
financial support. Duke Energy does not have the power to direct the activities 
that most significantly impact the economic performance, the obligation to 
absorb losses or the right to receive benefits of these VIEs and therefore does 
not consolidate these entities.

(a)  Duke Energy evaluated this investment for impairment as of December 31, 2019, and 2018, and 

determined that fair value approximated carrying value and therefore no impairment was necessary.
(b)  During the years ended December 31, 2019, and 2018, Duke Energy recorded an OTTI of $25 million and 
$55 million, respectively, related to Constitution within Equity in earnings of unconsolidated affiliates on 
Duke Energy’s Consolidated Statements of Income. The current year charge resulted in the full write-
down of Duke Energy’s investment in Constitution. See Notes 4 and 13 for additional information.

Duke Energy has investments in various renewable energy project entities. 

Some of these entities are VIEs due to Duke Energy issuing guarantees for debt 
service and operations and maintenance reserves in support of debt financings. 
Duke Energy does not consolidate these VIEs because power to direct and 
control key activities is shared jointly by Duke Energy and other owners. In 
2019, Duke Energy acquired a majority ownership in a portfolio of distributed 
fuel cell projects from Bloom Energy Corporation. Duke Energy is not the primary 
beneficiary of the assets within the portfolio and does not consolidate the assets 
in the portfolio.

OVEC

Duke Energy Ohio’s 9% ownership interest in OVEC is considered a non-
consolidated VIE due to OVEC having insufficient equity to finance its activities 
without subordinated financial support. The activities that most significantly 
impact OVEC’s economic performance include fuel strategy and supply activities 
and decisions associated with ongoing operations and maintenance-related 
activities. Duke Energy Ohio does not have the unilateral power to direct these 
activities, and therefore, does not consolidate OVEC.

As a counterparty to an Inter-Company Power Agreement (ICPA), Duke 

Energy Ohio has a contractual arrangement to receive entitlements to capacity 
and energy from OVEC’s power plants through June 2040 commensurate with its 
power participation ratio, which is equivalent to Duke Energy Ohio’s ownership 
interest. Costs, including fuel, operating expenses, fixed costs, debt amortization 
and interest expense, are allocated to counterparties to the ICPA based on their 
power participation ratio. The value of the ICPA is subject to variability due to 
fluctuation in power prices and changes in OVEC’s cost of business. On March 
31, 2018, FES, a subsidiary of FirstEnergy Corp. and an ICPA counterparty with a 
power participation ratio of 4.85%, filed for Chapter 11 bankruptcy, which could 

increase costs allocated to the counterparties. On July 31, 2018, the bankruptcy 
court rejected the FES ICPA, which means OVEC is an unsecured creditor in 
the FES bankruptcy proceeding. Duke Energy Ohio cannot predict the impact 
of the bankruptcy filing on its OVEC interests. In addition, certain proposed 
environmental rulemaking could result in future increased OVEC cost allocations. 
See Note 4 for additional information.

CRC

See discussion under Consolidated VIEs for additional information related 

to CRC.

Amounts included in Receivables from affiliated companies in the above 

table for Duke Energy Ohio and Duke Energy Indiana reflect their retained 
interest in receivables sold to CRC. These subordinated notes held by Duke 
Energy Ohio and Duke Energy Indiana are stated at fair value. Carrying values of 
retained interests are determined by allocating carrying value of the receivables 
between assets sold and interests retained based on relative fair value. The 
allocated bases of the subordinated notes are not materially different than 
their face value because (i) the receivables generally turnover in less than 
two months, (ii) credit losses are reasonably predictable due to the broad 
customer base and lack of significant concentration and (iii) the equity in CRC 
is subordinate to all retained interests and thus would absorb losses first. 
The hypothetical effect on fair value of the retained interests assuming both a 
10% and a 20% unfavorable variation in credit losses or discount rates is not 
material due to the short turnover of receivables and historically low credit loss 
history. Interest accrues to Duke Energy Ohio and Duke Energy Indiana on the 
retained interests using the acceptable yield method. This method generally 
approximates the stated rate on the notes since the allocated basis and the 
face value are nearly equivalent. An impairment charge is recorded against 
the carrying value of both retained interests and purchased beneficial interest 
whenever it is determined that an OTTI has occurred.

Key assumptions used in estimating fair value are detailed in the following table.

Cash flows from sales of receivables are reflected within Cash Flows 
From Operating Activities on Duke Energy Ohio’s and Duke Energy Indiana’s 
Consolidated Statements of Cash Flows.

Collection fees received in connection with servicing transferred accounts 

receivable are included in Operation, maintenance and other on Duke Energy 
Ohio’s and Duke Energy Indiana’s Consolidated Statements of Operations 
and Comprehensive Income. The loss recognized on sales of receivables is 

calculated monthly by multiplying receivables sold during the month by the 
required discount. The required discount is derived monthly utilizing a 
three-year weighted average formula that considers charge-off history, late 
charge history and turnover history on the sold receivables, as well as a 
component for the time value of money. The discount rate, or component for the 
time value of money, is the prior month-end LIBOR plus a fixed rate of 1.00%.

19.  REVENUE

Duke Energy recognizes revenue consistent with amounts billed under 
tariff offerings or at contractually agreed upon rates based on actual physical 
delivery of electric or natural gas service, including estimated volumes delivered 
when billings have not yet occurred. As such, the majority of Duke Energy’s 
revenues have fixed pricing based on the contractual terms of the published 
tariffs, with variability in expected cash flows attributable to the customer’s 
volumetric demand and ultimate quantities of energy or natural gas supplied 
and used during the billing period. The stand-alone selling price of related sales 
are designed to support recovery of prudently incurred costs and an appropriate 
return on invested assets and are primarily governed by published tariff rates 
or contractual agreements approved by relevant regulatory bodies. As described 
in Note 1, certain excise taxes and franchise fees levied by state or local 
governments are required to be paid even if not collected from the customer. 
These taxes are recognized on a gross basis as part of revenues. Duke Energy 
elects to account for all other taxes net of revenues.

Performance obligations are satisfied over time as energy or natural gas 

is delivered and consumed with billings generally occurring monthly and related 
payments due within 30 days, depending on regulatory requirements. In no 
event does the timing between payment and delivery of the goods and services 
exceed one year. Using this output method for revenue recognition provides a 
faithful depiction of the transfer of electric and natural gas service as customers 
obtain control of the commodity and benefit from its use at delivery. Additionally, 
Duke Energy has an enforceable right to consideration for energy or natural gas 
delivered at any discrete point in time and will recognize revenue at an amount 
that reflects the consideration to which Duke Energy is entitled for the energy or 
natural gas delivered.

As described above, the majority of Duke Energy’s tariff revenues are 

at-will and, as such, related contracts with customers have an expected 
duration of one year or less and will not have future performance obligations for 
disclosure. Additionally, other long-term revenue streams, including wholesale 
contracts, generally provide services that are part of a single performance 

obligation, the delivery of electricity or natural gas. As such, other than material 
fixed consideration under long-term contracts, related disclosures for future 
performance obligations are also not applicable.

Duke Energy earns substantially all of its revenues through its reportable 
segments, Electric Utilities and Infrastructure, Gas Utilities and Infrastructure 
and Commercial Renewables.

Electric Utilities and Infrastructure

Electric Utilities and Infrastructure earns the majority of its revenues 

through retail and wholesale electric service through the generation, 
transmission, distribution and sale of electricity. Duke Energy generally provides 
retail and wholesale electric service customers with their full electric load 
requirements or with supplemental load requirements when the customer has 
other sources of electricity.

Retail electric service is generally marketed throughout Duke Energy’s 

electric service territory through standard service offers. The standard service 
offers are through tariffs determined by regulators in Duke Energy’s regulated 
service territory. Each tariff, which is assigned to customers based on customer 
class, has multiple components such as an energy charge, a demand charge, 
a basic facilities charge and applicable riders. Duke Energy considers each 
of these components to be aggregated into a single performance obligation 
for providing electric service, or in the case of distribution only customers in 
Duke Energy Ohio, for delivering electricity. Electricity is considered a single 
performance obligation satisfied over time consistent with the series guidance 
and is provided and consumed over the billing period, generally one month. 
Retail electric service is typically provided to at-will customers who can cancel 
service at any time, without a substantive penalty. Additionally, Duke Energy 
adheres to applicable regulatory requirements in each jurisdiction to ensure 
the collectability of amounts billed and appropriate mitigating procedures are 
followed when necessary. As such, revenue from contracts with customers for

(including unbilled estimates).

Wholesale electric service is generally provided under long-term 
contracts using cost-based pricing. FERC regulates costs that may be 
recovered from customers and the amount of return companies are permitted 
to earn. Wholesale contracts include both energy and demand charges. For 
full requirements contracts, Duke Energy considers both charges as a single 
performance obligation for providing integrated electric service. For contracts 
where energy and demand charges are considered separate performance 
obligations, energy and demand are each a distinct performance obligation 
under the series guidance and are satisfied as energy is delivered and 
stand-ready service is provided on a monthly basis. This service represents 
consumption over the billing period and revenue is recognized consistent with 

billings and unbilled estimates, which generally occur monthly. Contractual 
amounts owed are typically trued up annually based upon incurred costs in 
accordance with FERC published filings and the specific customer’s actual 
peak demand. Estimates of variable consideration related to potential additional 
billings or refunds owed are updated quarterly.

The majority of wholesale revenues are full requirements contracts where 

the customers purchase the substantial majority of their energy needs and do 
not have a fixed quantity of contractually required energy or capacity. As such, 
related forecasted revenues are considered optional purchases. Supplemental 
requirements contracts that include contracted blocks of energy and capacity at 
contractually fixed prices have the following estimated remaining performance 
obligations:

Revenues for block sales are recognized monthly as energy is delivered 

and stand-ready service is provided, consistent with invoiced amounts and 
unbilled estimates.

Gas Utilities and Infrastructure

Gas Utilities and Infrastructure earns its revenue through retail and 
wholesale natural gas service through the transportation, distribution and sale 
of natural gas. Duke Energy generally provides retail and wholesale natural gas 
service customers with all natural gas load requirements. Additionally, while 
natural gas can be stored, substantially all natural gas provided by Duke Energy 
is consumed by customers simultaneously with receipt of delivery.

Retail natural gas service is marketed throughout Duke Energy’s natural 
gas service territory using published tariff rates. The tariff rates are established 
by regulators in Duke Energy’s service territories. Each tariff, which is assigned 
to customers based on customer class, have multiple components, such 
as a commodity charge, demand charge, customer or monthly charge and 
transportation costs. Duke Energy considers each of these components to 
be aggregated into a single performance obligation for providing natural gas 
service. For contracts where Duke Energy provides all of the customer’s natural 
gas needs, the delivery of natural gas is considered a single performance 

obligation satisfied over time, and revenue is recognized monthly based on 
billings and unbilled estimates as service is provided and the commodity is 
consumed over the billing period. Additionally, natural gas service is typically 
at-will and customers can cancel service at any time, without a substantive 
penalty. Duke Energy also adheres to applicable regulatory requirements to 
ensure the collectability of amounts billed and receivable and appropriate 
mitigating procedures are followed when necessary.

Certain long-term individually negotiated contracts exist to provide natural 
gas service. These contracts are regulated and approved by state commissions. 
The negotiated contracts have multiple components, including a natural gas and 
a demand charge, similar to retail natural gas contracts. Duke Energy considers 
each of these components to be a single performance obligation for providing 
natural gas service. This service represents consumption over the billing period, 
generally one month.

Fixed capacity payments under long-term contracts for the Gas Utilities 

and Infrastructure segment include minimum margin contracts and supply 
arrangements with municipalities and power generation facilities. Revenues 
for related sales are recognized monthly as natural gas is delivered and 
stand-ready service is provided, consistent with invoiced amounts and unbilled 
estimates. Estimated remaining performance obligations are as follows:

Commercial Renewables earns the majority of its revenues through 
long-term PPAs and generally sells all of its wind and solar facility output, 
electricity and RECs to customers. The majority of these PPAs have historically 
been accounted for as leases. For PPAs that are not accounted for as leases, 
the delivery of electricity and the delivery of RECs are considered separate 
performance obligations.

The delivery of electricity is a performance obligation satisfied over time 

and represents generation and consumption of the electricity over the billing 
period, generally one month. The delivery of RECs is a performance obligation 
satisfied at a point in time and represents delivery of each REC generated by 
the wind or solar facility. The majority of self-generated RECs are bundled 
with energy in Duke Energy’s contracts and, as such, related revenues are 
recognized as energy is generated and delivered as that pattern is consistent 
with Duke Energy’s performance. Commercial Renewables recognizes revenue 
based on the energy generated and billed for the period, generally one month, 
at contractual rates (including unbilled estimates) according to the invoice 
practical expedient. Amounts are typically due within 30 days of invoice.
Commercial Renewables also earns revenues from installation of 
distributed solar generation resources, which is primarily composed of EPC 
projects to deliver functioning solar power systems, generally completed 
within two to 12 months from commencement of construction. The installation 
of distributed solar generation resources is a performance obligation that is 
satisfied over time. Revenue from fixed-price EPC contracts is recognized using 

the input method as work is performed based on the estimated ratio of incurred 
costs to estimated total costs.

Other

The remainder of Duke Energy’s operations is presented as Other, which 

does not include material revenues from contracts with customers.

Disaggregated Revenues

For the Electric and Gas Utility and Infrastructure segments, revenue by 

customer class is most meaningful to Duke Energy as each respective customer 
class collectively represents unique customer expectations of service, generally 
has different energy and demand requirements, and operates under tailored, 
regulatory approved pricing structures. Additionally, each customer class is 
impacted differently by weather and a variety of economic factors including 
the level of population growth, economic investment, employment levels, and 
regulatory activities in each of Duke Energy’s jurisdictions. As such, analyzing 
revenues disaggregated by customer class allows Duke Energy to understand 
the nature, amount, timing and uncertainty of revenue and cash flows arising 
from contracts with customers. For the Commercial Renewables segment, the 
majority of revenues from contracts with customers are from selling all of the 
unit-contingent output at contractually defined pricing under long-term PPAs 
with consistent expectations regarding the timing and certainty of cash flows.

IMPACT OF WEATHER AND THE TIMING OF BILLING PERIODS

Revenues and costs are influenced by seasonal weather patterns. Peak 
sales of electricity occur during the summer and winter months, which results 
in higher revenue and cash flows during these periods. By contrast, lower sales 
of electricity occur during the spring and fall, allowing for scheduled plant 
maintenance. Residential and general service customers are more impacted 
by weather than industrial customers. Estimated weather impacts are based 
on actual current period weather compared to normal weather conditions. 
Normal weather conditions are defined as the long-term average of actual 
historical weather conditions. Heating degree days measure the variation in 
weather based on the extent the average daily temperature falls below a base 
temperature. Cooling degree days measure the variation in weather based on 
the extent the average daily temperature rises above the base temperature. 
Each degree of temperature below the base temperature counts as one heating 
degree day and each degree of temperature above the base temperature counts 
as one cooling degree day.

The estimated impact of weather on earnings for Electric Utilities and 

Infrastructure is based on the temperature variances from a normal condition 
and customers’ historic usage patterns. The methodology used to estimate the 
impact of weather does not consider all variables that may impact customer 
response to weather conditions, such as humidity in the summer or wind chill 

in the winter. The precision of this estimate may also be impacted by applying 
long-term weather trends to shorter-term periods.

Gas Utilities and Infrastructure’s costs and revenues are influenced by 
seasonal patterns due to peak natural gas sales occurring during the winter 
months as a result of space heating requirements. Residential customers are 
the most impacted by weather. There are certain regulatory mechanisms for the 
North Carolina, South Carolina, Tennessee, Ohio and Kentucky service territories 
that normalize the margins collected from certain customer classes during the 
winter. In North Carolina, rate design provides protection from both weather and 
other usage variations such as conservation, while South Carolina, Tennessee 
and Kentucky revenues are adjusted solely based on weather. Ohio primarily 
employs a fixed charge each month regardless of the season and usage.

UNBILLED REVENUE

Unbilled revenues are recognized by applying customer billing rates to the 
estimated volumes of energy or natural gas delivered but not yet billed. Unbilled 
revenues can vary significantly from period to period as a result of seasonality, 
weather, customer usage patterns, customer mix, average price in effect 
for customer classes, timing of rendering customer bills and meter reading 
schedules, and the impact of weather normalization or margin decoupling 
mechanisms.

Basic EPS is computed by dividing net income available to Duke Energy 
common stockholders, as adjusted for distributed and undistributed earnings 
allocated to participating securities, by the weighted average number of 
common shares outstanding during the period. Diluted EPS is computed by 
dividing net income available to Duke Energy common stockholders, as adjusted 
for distributed and undistributed earnings allocated to participating securities, 
by the diluted weighted average number of common shares outstanding 
during the period. Diluted EPS reflects the potential dilution that could occur if 

securities or other agreements to issue common stock, such as stock options 
and equity forward sale agreements, were exercised or settled. Duke Energy’s 
participating securities are RSUs that are entitled to dividends declared on Duke 
Energy common stock during the RSUs vesting periods. Dividends declared 
on preferred stock are recorded on the Consolidated Statements of Operations 
as a reduction of net income to arrive at net income available to Duke Energy 
common stockholders. Dividends accumulated on preferred stock are a 
reduction to net income used in the calculation of basic and diluted EPS.

The following table presents Duke Energy’s basic and diluted EPS calculations, the weighted average number of common shares outstanding and common and 

preferred share dividends declared.

Common Stock

In February 2018, Duke Energy filed a prospectus supplement and executed 
an Equity Distribution Agreement (EDA) under which it may sell up to $1 billion of 
its common stock through an ATM offering program, including an equity forward 
sales component. Under the terms of the EDA, Duke Energy was allowed to issue 
and sell shares of common stock. The existing ATM offering program expired in 
September 2019.

In June 2018, Duke Energy marketed two separate tranches, each for 
1.3 million shares, of common stock through equity forward transactions under 
the ATM program. In December 2018, Duke Energy physically settled these equity 
forwards by delivering 2.6 million shares of common stock in exchange for net 
proceeds of approximately $195 million.

In March 2018, Duke Energy marketed an equity offering of 21.3 million 

shares of common stock through an Underwriting Agreement. In connection with 
the offering, Duke Energy entered into equity forward sale agreements. The equity

issuing 21.3 million shares in exchange for net proceeds at the then-applicable 
forward sale price specified by the agreements, or net settle in whole or in part 
through the delivery or receipt of cash or shares. In June 2018, Duke Energy 
physically settled one-half of the equity forwards by delivering approximately 
10.6 million shares of common stock in exchange for net cash proceeds of 
approximately $781 million. In December 2018, Duke Energy physically settled 
the remaining equity forward by delivering 10.6 million shares of common stock 
in exchange for net cash proceeds of approximately $766 million.

In March and April 2019, Duke Energy marketed two separate tranches, 
each for 1.1 million shares, of common stock through equity forward transactions 
under the ATM program. The first tranche had an initial forward price of 
$89.83 per share and the second tranche had an initial forward price of 
$88.82 per share. In May and June 2019, a third tranche of 1.6 million shares 
of common stock was marketed and had an initial forward price of $86.23. The 
equity forwards required Duke Energy to either physically settle the transaction 
by issuing shares in exchange for net proceeds at the then-applicable forward 
sale price specified by the agreements or net settle in whole or in part through 
the delivery or receipt of cash or shares. The settlement alternative was at Duke 
Energy’s election. In December 2019, Duke Energy physically settled the equity 
forwards by delivering 3.8 million shares of common stock in exchange for net 
cash proceeds of approximately $331 million.

In November 2019, Duke Energy filed a prospectus supplement and 
executed an EDA under which it may sell up to $1.5 billion of its common 
stock through a new ATM offering program, including an equity forward sales 
component. Under the terms of the EDA, Duke Energy may issue and sell shares 
of common stock through September 2022.

In November 2019, Duke Energy marketed an equity offering of 
28.75 million shares of common stock through an Underwriting Agreement. 
In connection with the offering, Duke Energy entered into equity forward sales 
agreements with an initial forward price of $85.99 per share. The equity forward 
sales agreements require Duke Energy to either physically settle the transaction 
by issuing shares in exchange for net proceeds at the then-applicable forward 
sale price specified by the agreement, or net settle in whole or in part through 
the delivery or receipt of cash or shares. The settlement alternatives are at Duke 
Energy’s election. Settlement of the forward sales agreements are expected to 
occur on or prior to December 31, 2020. If Duke Energy had elected to net share 
settle these contracts as of December 31, 2019, Duke Energy would have been 
required to deliver 1.6 million shares.

For the years ended December 31, 2019, and 2018, Duke Energy issued 
1.8 million and 2.2 million shares, respectively, through its DRIP with an increase 
in additional paid-in capital of approximately $160 million and $174 million, 
respectively.

Preferred Stock

On March 29, 2019, Duke Energy completed the issuance of 40 million 
depositary shares, each representing 1/1,000th share of its Series A Cumulative 
Redeemable Perpetual Preferred Stock, at a price of $25 per depositary share. 
The transaction resulted in net proceeds of $973 million after issuance costs with 
proceeds used for general corporate purposes and to reduce short-term debt. 
The preferred stock has a $25 liquidation preference per depositary share and 
earns dividends on a cumulative basis at a rate of 5.75% per annum. Dividends 
are payable quarterly in arrears on the 16th day of March, June, September and 
December, and began on June 16, 2019.

The Series A Preferred Stock has no maturity or mandatory redemption 
date, is not redeemable at the option of the holders and includes separate call 

options. The first call option allows Duke Energy to call the Series A Preferred 
Stock at a redemption price of $25.50 per depositary share prior to June 15, 
2024, in whole but not in part, at any time within 120 days after a ratings event 
where a rating agency amends, clarifies or changes the criteria it uses to assign 
equity credit for securities such as the preferred stock. The second call option 
allows Duke Energy to call the preferred stock, in whole or in part, at any time, on 
or after June 15, 2024, at a redemption price of $25 per depositary share. Duke 
Energy is also required to redeem all accumulated and unpaid dividends if either 
call option is exercised.

On September 12, 2019, Duke Energy completed the issuance of 1 million 

shares of its Series B Fixed-Rate Reset Cumulative Redeemable Perpetual 
Preferred Stock, at a price of $1,000 per share. The transaction resulted in 
net proceeds of $989 million after issuance costs with proceeds being used 
to pay down short-term debt, repay at maturity $500 million senior notes due 
September 2019, and for general corporate purposes. The preferred stock 
has a $1,000 liquidation preference per share and earns dividends on a 
cumulative basis at an initial rate of 4.875% per annum. Dividends are payable 
semiannually in arrears on the 16th day of March and September, beginning 
on March 16, 2020. On September 16, 2024, the First Call Date, and any fifth 
anniversary of the First Call Date (each a Reset Date), the dividend rate will reset 
based on the then current five-year U.S. treasury rate plus a spread of 3.388%.

The Series B Preferred Stock has no maturity or mandatory redemption 
date, is not redeemable at the option of the holders and includes separate call 
options. The first call option allows Duke Energy to call the Series B Preferred 
Stock at a redemption price of $1,020 per share, in whole but not in part, at any 
time within 120 days after a ratings event. The second call option allows Duke 
Energy to call the preferred stock, in whole or in part, on the First Call Date or any 
subsequent Reset Date at a redemption price in cash equal to $1,000 per share. 
Duke Energy is also required to redeem all accumulated and unpaid dividends if 
either call option is exercised.

Dividends issued on its Series A and Series B Preferred Stock are subject 

to approval by the Board of Directors. However, the deferral of dividend payments 
on the preferred stock prohibits the declaration of common stock dividends.

The Series A and Series B Preferred Stock rank, with respect to dividends 

and distributions upon liquidation or dissolution:

• senior to Common Stock and to each other class or series of capital 

stock established after the original issue date of the Series A and Series 
B Preferred Stock that is expressly made subordinated to the Series A 
and Series B Preferred Stock;

• on a parity with any class or series of capital stock established after the 
original issue date of the Series A and Series B Preferred Stock that is 
not expressly made senior or subordinated to the Series A or Series B 
Preferred Stock;

• junior to any class or series of capital stock established after the 

original issue date of the Series A and Series B Preferred Stock that is 
expressly made senior to the Series A or Series B Preferred Stock;

• junior to all existing and future indebtedness (including indebtedness 
outstanding under Duke Energy’s credit facilities, unsecured senior 
notes, junior subordinated debentures and commercial paper) and other 
liabilities with respect to assets available to satisfy claims against Duke 
Energy; and

liabilities of Duke Energy’s subsidiaries and future preferred stock of 
subsidiaries.

Holders of Series A and Series B Preferred Stock have no voting rights with 
respect to matters that generally require the approval of voting stockholders. The 
limited voting rights of holders of Series A and Series B Preferred Stock include 
the right to vote as a single class, respectively, on certain matters that may affect 

the preference or special rights of the preferred stock, except in the instance that 
Duke Energy elects to defer the payment of dividends for a total of six quarterly 
full dividend periods for Series A Preferred Stock or three semiannual full dividend 
periods for Series B Preferred Stock. If dividends are deferred for a cumulative 
total of six quarterly full dividend periods for Series A Preferred Stock or three 
semiannual full dividend periods for Series B Preferred Stock, whether or not for 
consecutive dividend periods, holders of the respective preferred stock have the 
right to elect two additional Board members to the Board of Directors.

21.  SEVERANCE

During 2018, Duke Energy reviewed its operations and identified 
opportunities for improvement to better serve its customers. This operational 
review included the company’s workforce strategy and staffing levels to ensure 
the company was staffed with the right skillsets and number of teammates to 
execute the long-term vision for Duke Energy. As such, Duke Energy extended 
voluntary and involuntary severance benefits to certain employees in specific 
areas as a part of workforce planning and digital transformation efforts.

The following table presents the direct and allocated severance and 
related charges accrued for approximately 140 employees in 2019, 1,900 
employees in 2018 and 100 employees in 2017 by the Duke Energy Registrants 
within Operation, maintenance and other on the Consolidated Statements of 
Operations.

22.  STOCK-BASED COMPENSATION

The Duke Energy Corporation 2015 Long-Term Incentive Plan (the 2015 

Plan) provides for the grant of stock-based compensation awards to employees 
and outside directors. The 2015 Plan reserves 10 million shares of common stock 
for issuance. Duke Energy has historically issued new shares upon exercising or 
vesting of share-based awards. However, Duke Energy may use a combination of 
new share issuances and open market repurchases for share-based awards that 
are exercised or vest in the future. Duke Energy has not determined with certainty 
the amount of such new share issuances or open market repurchases.

The following table summarizes the total expense recognized by the Duke 

Energy Registrants, net of tax, for stock-based compensation.

RESTRICTED STOCK UNIT AWARDS

RSU awards generally vest over periods from immediate to three years. 
Fair value amounts are based on the market price of Duke Energy’s common 
stock on the grant date. The following table includes information related to 
RSU awards.

Performance awards contain performance conditions and a market 
condition. The performance conditions are based on Duke Energy’s cumulative 
adjusted EPS and total incident case rate (total incident case rate is one of our 
key employee safety metrics). The market condition is based on TSR of Duke 
Energy relative to a predefined peer group.

Relative TSR is valued using a path-dependent model that incorporates 

expected relative TSR into the fair value determination of Duke Energy’s 
performance-based share awards. The model uses three-year historical 
volatilities and correlations for all companies in the predefined peer group, 
including Duke Energy, to simulate Duke Energy’s relative TSR as of the end 
of the performance period. For each simulation, Duke Energy’s relative TSR 
associated with the simulated stock price at the end of the performance period 
plus expected dividends within the period results in a value per share for the 
award portfolio. The average of these simulations is the expected portfolio value 
per share. Actual life to date results of Duke Energy’s relative TSR for each 
grant are incorporated within the model. For performance awards granted in 
2019, the model used a risk-free interest rate of 2.5%, which reflects the yield 
on three-year Treasury bonds as of the grant date, and an expected volatility of 
14.8% based on Duke Energy’s historical volatility over three years using daily 
stock prices.

of unrecognized compensation cost, which is expected to be recognized over 
a weighted average period of 23 months. Prior to Duke Energy’s acquisition 
of Piedmont, Piedmont had an incentive compensation plan that had a series 
of three-year performance and RSU awards for eligible officers and other 
participants. The 2016-2018 performance award cycle was approved subsequent 
to the Agreement and Plan of Merger between Duke Energy and Piedmont and was 
converted into a Duke Energy RSU award at the consummation of the acquisition.

PERFORMANCE AWARDS

Stock-based performance awards generally vest after three years if 

performance targets are met. The actual number of shares issued will range 
from zero to 200% of target shares, depending on the level of performance 
achieved.

EMPLOYEE BENEFIT PLANS

DEFINED BENEFIT RETIREMENT PLANS

Duke Energy and certain subsidiaries maintain, and the Subsidiary 
Registrants participate in, qualified, non-contributory defined benefit retirement 
plans. The Duke Energy plans cover most employees using a cash balance 
formula. Under a cash balance formula, a plan participant accumulates a 
retirement benefit consisting of pay credits based upon a percentage of current 
eligible earnings, age or age and years of service and interest credits. Certain 
employees are eligible for benefits that use a final average earnings formula. 
Under these final average earnings formulas, a plan participant accumulates 
a retirement benefit equal to the sum of percentages of their (i) highest three-
year, four-year, or five-year average earnings, (ii) highest three-year, four-year, 
or five-year average earnings in excess of covered compensation per year of 
participation (maximum of 35 years) or (iii) highest three-year average earnings 
times years of participation in excess of 35 years. Duke Energy also maintains, 
and the Subsidiary Registrants participate in, non-qualified, non-contributory 
defined benefit retirement plans that cover certain executives. The qualified 
and non-qualified, non-contributory defined benefit plans are closed to new 
participants.

Duke Energy approved plan amendments to restructure its qualified 

non-contributory defined benefit retirement plans, effective January 1, 2018. 
The restructuring involved (i) the spin-off of the majority of inactive participants 
from two plans into a separate inactive plan and (ii) the merger of the active 
participant portions of such plans, along with a pension plan acquired as part 
of the Piedmont transaction, into a single active plan. Benefits offered to the 
plan participants remain unchanged except that the Piedmont plan’s final 
average earnings formula was frozen as of December 31, 2017, and affected 
participants were moved into the active plan’s cash balance formula. Actuarial 
gains and losses associated with the Inactive Plan will be amortized over the 
remaining life expectancy of the inactive participants. The longer amortization 
period lowered Duke Energy’s 2018 pretax qualified pension plan expense by 
approximately $33 million.

Duke Energy uses a December 31 measurement date for its defined 

benefit retirement plan assets and obligations.

As a result of the application of settlement accounting due to total 
lump-sum benefit payments exceeding the settlement threshold (defined as 
the sum of the service cost and interest cost on projected benefit obligation 
components of net periodic pension costs) for one of its qualified pension 
plans, Duke Energy recognized settlement charges of $94 million, primarily as 
a regulatory asset within Other Noncurrent Assets on the Consolidated Balance 
Sheets as of December 31, 2019 (an immaterial amount was recorded in Other 
income and expenses, net within the Consolidated Statement of Operations).

Settlement charges recognized by the Subsidiary Registrants as of 
December 31, 2019, which represent amounts allocated by Duke Energy 
for employees of the Subsidiary Registrants and allocated charges for their 
proportionate share of settlement charges for employees of Duke Energy’s 
shared services affiliate, were $53 million for Duke Energy Carolinas, 
$26 million for Progress Energy, $20 million for Duke Energy Progress, $6 million 
for Duke Energy Florida, $4 million for Duke Energy Indiana, $2 million for Duke 
Energy Ohio and $8 million for Piedmont.

The settlement charges reflect the recognition of a pro-rata portion of 
previously unrecognized actuarial losses, equal to the percentage of reduction in 
the projected benefit obligation resulting from total lump-sum benefit payments 
as of December 31, 2019. Settlement charges recognized as a regulatory 
asset within Other Noncurrent Assets on the Consolidated Balance Sheets are 
amortized over the average remaining service period for participants in the 
plan. Amortization of settlement charges is disclosed in the tables below as a 
component of net periodic pension costs.

Net periodic benefit costs disclosed in the tables below represent the cost 
of the respective benefit plan for the periods presented prior to capitalization of 
amounts reflected as Net property, plant and equipment, on the Consolidated 
Balance Sheets. Only the service cost component of net periodic benefit 
costs is eligible to be capitalized. The remaining non-capitalized portions of 
net periodic benefit costs are classified as either: (1) service cost, which is 
recorded in Operations, maintenance and other on the Consolidated Statements 
of Operations; or as (2) components of non-service cost, which is recorded in 
Other income and expenses, net, on the Consolidated Statements of Operations. 
Amounts presented in the tables below for the Subsidiary Registrants represent 
the amounts of pension and other post-retirement benefit cost allocated by 
Duke Energy for employees of the Subsidiary Registrants. Additionally, the 
Consolidated Statements of Operations of the Subsidiary Registrants also 
include allocated net periodic benefit costs for their proportionate share of 
pension and post-retirement benefit cost for employees of Duke Energy’s 
shared services affiliate that provide support to the Subsidiary Registrants. 
However, in the tables below, these amounts are only presented within the Duke 
Energy column (except for amortization of settlement charges). These allocated 
amounts are included in the governance and shared service costs discussed in 
Note 14.

Duke Energy’s policy is to fund amounts on an actuarial basis to provide 
assets sufficient to meet benefit payments to be paid to plan participants. Duke 
Energy does not anticipate making any contributions in 2020. The following table 
includes information related to the Duke Energy Registrants’ contributions to its 
qualified defined benefit pension plans.

Assumptions Used for Pension Benefits Accounting

The discount rate used to determine the current year pension obligation and following year’s pension expense is based on a bond selection-settlement portfolio 

approach. This approach develops a discount rate by selecting a portfolio of high quality corporate bonds that generate sufficient cash flow to provide for projected 
benefit payments of the plan. The selected bond portfolio is derived from a universe of non-callable corporate bonds rated Aa quality or higher. After the bond portfolio 
is selected, a single interest rate is determined that equates the present value of the plan’s projected benefit payments discounted at this rate with the market value 
of the bonds selected.

The average remaining service period for participants in active plans and life expectancy of participants in inactive plans is 12 years for Duke Energy, Duke 
Energy Carolinas, Progress Energy and Duke Energy Florida, 13 years for Duke Energy Progress, Duke Energy Indiana and Duke Energy Ohio, and 9 years for Piedmont.

Assumptions Used for Other Post-Retirement Benefits Accounting

The discount rate used to determine the current year other post-retirement benefits obligation and following year’s other post-retirement benefits expense is 
based on a bond selection-settlement portfolio approach. This approach develops a discount rate by selecting a portfolio of high quality corporate bonds that generate 
sufficient cash flow to provide for projected benefit payments of the plan. The selected bond portfolio is derived from a universe of non-callable corporate bonds rated 
Aa quality or higher. After the bond portfolio is selected, a single interest rate is determined that equates the present value of the plan’s projected benefit payments 
discounted at this rate with the market value of the bonds selected.

Description and Allocations

Duke Energy Master Retirement Trust

Assets for both the qualified pension and other post-retirement benefits 

are maintained in the Duke Energy Master Retirement Trust. Approximately 98% 
of the Duke Energy Master Retirement Trust assets were allocated to qualified 
pension plans and approximately 2% were allocated to other post-retirement 
plans (comprised of 401(h) accounts), as of December 31, 2019, and 2018. The 
investment objective of the Duke Energy Master Retirement Trust is to invest in 
a diverse portfolio of assets that is expected to generate positive surplus return 
over time (i.e. asset growth greater than liability growth) subject to a prudent 
level of portfolio risk, for the purpose of enhancing the security of benefits for 
plan participants.

As of December 31, 2019, Duke Energy assumes pension and other 
post-retirement plan assets will generate a long-term rate of return of 6.85%. 
The expected long-term rate of return was developed using a weighted 
average calculation of expected returns based primarily on future expected 
returns across asset classes considering the use of active asset managers, 
where applicable. The asset allocation targets were set after considering the 
investment objective and the risk profile. Equity securities are held for their 
higher expected returns. Debt securities are primarily held to hedge the qualified 
pension plan liability. Real assets, return seeking fixed income, hedge funds 
and other global securities are held for diversification. Investments within asset 
classes are diversified to achieve broad market participation and reduce the 
impact of individual managers or investments.

Effective January 1, 2019, the target asset allocation for the Duke Energy 

Retirement Master Trust is 58% liability hedging assets and 42% return-seeking 
assets. Duke Energy periodically reviews its asset allocation targets, and over 
time, as the funded status of the benefit plans increase, the level of asset 
risk relative to plan liabilities may be reduced to better manage Duke Energy’s 
benefit plan liabilities and reduce funded status volatility.

The Duke Energy Master Retirement Trust is authorized to engage in the 

lending of certain plan assets. Securities lending is an investment management 
enhancement that utilizes certain existing securities of the Duke Energy Master 
Retirement Trust to earn additional income. Securities lending involves the 
loaning of securities to approved parties. In return for the loaned securities, the 
Duke Energy Master Retirement Trust receives collateral in the form of cash and 
securities as a safeguard against possible default of any borrower on the return 
of the loan under terms that permit the Duke Energy Master Retirement Trust 
to sell the securities. The Duke Energy Master Retirement Trust mitigates credit 
risk associated with securities lending arrangements by monitoring the fair 
value of the securities loaned, with additional collateral obtained or refunded 
as necessary. The fair value of securities on loan was approximately $351 
million and $154 million at December 31, 2019, and 2018, respectively. Cash 
and securities obtained as collateral exceeded the fair value of the securities 
loaned at December 31, 2019, and 2018, respectively. Securities lending income 
earned by the Duke Energy Master Retirement Trust was immaterial for the years 
ended December 31, 2019, 2018 and 2017, respectively.

Qualified pension and other post-retirement benefits for the Subsidiary 

Registrants are derived from the Duke Energy Master Retirement Trust, as such, 
each are allocated their proportionate share of the assets discussed below.

Retirement Trust.

Fair Value Measurements

Investments in real estate limited partnerships

Duke Energy classifies recurring and non-recurring fair value 
measurements based on the fair value hierarchy as discussed in Note 17.

Valuation methods of the primary fair value measurements disclosed 

below are as follows:

Investments in equity securities

Investments in equity securities are typically valued at the closing price in 

the principal active market as of the last business day of the reporting period. 
Principal active markets for equity prices include published exchanges such 
as NASDAQ and NYSE. Foreign equity prices are translated from their trading 
currency using the currency exchange rate in effect at the close of the principal 
active market. Prices have not been adjusted to reflect after-hours market 
activity. The majority of investments in equity securities are valued using 
Level 1 measurements. When the price of an institutional commingled fund is 
unpublished, it is not categorized in the fair value hierarchy, even though the 
funds are readily available at the fair value.

Investments in corporate debt securities and U.S. government securities

Most debt investments are valued based on a calculation using interest 

rate curves and credit spreads applied to the terms of the debt instrument 
(maturity and coupon interest rate) and consider the counterparty credit rating. 
Most debt valuations are Level 2 measurements. If the market for a particular 
fixed-income security is relatively inactive or illiquid, the measurement is 
Level 3. U.S. Treasury debt is typically Level 2.

Investments in short-term investment funds

Investments in short-term investment funds are valued at the net asset 
value of units held at year end and are readily redeemable at the measurement 
date. Investments in short-term investment funds with published prices 
are valued as Level 1. Investments in short-term investment funds with 
unpublished prices are valued as Level 2.

Duke Energy Master Retirement Trust

Investments in real estate limited partnerships are valued by the trustee 

at each valuation date (monthly). As part of the trustee’s valuation process, 
properties are externally appraised generally on an annual basis, conducted 
by reputable, independent appraisal firms, and signed by appraisers that are 
members of the Appraisal Institute, with the professional designation MAI. Fair 
value is defined as the price that would be received to sell an asset or paid to 
transfer a liability in an orderly transaction between market participants at the 
measurement date. There are three valuation techniques that can be used to 
value investments in real estate assets: the market, income or cost approach. 
The appropriateness of each valuation technique depends on the type of 
asset or business being valued. In addition, the trustee may cause additional 
appraisals to be performed as warranted by specific asset or market conditions. 
Property valuations and the salient valuation-sensitive assumptions of each 
direct investment property are reviewed by the trustee quarterly and values 
are adjusted if there has been a significant change in circumstances related to 
the investment property since the last valuation. Value adjustments for interim 
capital expenditures are only recognized to the extent that the valuation process 
acknowledges a corresponding increase in fair value. An independent firm is 
hired to review and approve quarterly direct real estate valuations. Key inputs 
and assumptions used to determine fair value includes among others, rental 
revenue and expense amounts and related revenue and expense growth rates, 
terminal capitalization rates and discount rates. Development investments 
are valued using cost incurred to date as a primary input until substantive 
progress is achieved in terms of mitigating construction and leasing risk at 
which point a discounted cash flow approach is more heavily weighted. Key 
inputs and assumptions in addition to those noted above used to determine 
the fair value of development investments include construction costs and the 
status of construction completion and leasing. Investments in real estate limited 
partnerships are valued at net asset value of units held at year end and are not 
readily redeemable at the measurement date. Investments in real estate limited 
partnerships are not categorized within the fair value hierarchy.

The following tables provide the fair value measurement amounts for the Duke Energy Master Retirement Trust qualified pension and other post-retirement assets.

EMPLOYEE SAVINGS PLANS

Retirement Savings Plan

Duke Energy or its affiliates sponsor, and the Subsidiary Registrants 
participate in, employee savings plans that cover substantially all U.S. employees. 
Most employees participate in a matching contribution formula where Duke 
Energy provides a matching contribution generally equal to 100% of employee 
before-tax and Roth 401(k) contributions of up to 6% of eligible pay per pay 
period. Dividends on Duke Energy shares held by the savings plans are charged 

to retained earnings when declared and shares held in the plans are considered 
outstanding in the calculation of basic and diluted EPS.

For new and rehired employees who are not eligible to participate in Duke 

Energy’s defined benefit plans, an additional employer contribution of 4% of 
eligible pay per pay period, which is subject to a three-year vesting schedule, is 
provided to the employee’s savings plan account. Certain Piedmont employees 
whose participation in a prior Piedmont defined benefit plan (that was frozen as 
of December 31, 2017) are eligible for employer transition credit contributions 
of 3% to 5% of eligible pay per period, for each pay period during the three-year 
period ending December 31, 2020.

The following table includes pretax employer matching contributions made by Duke Energy and expensed by the Subsidiary Registrants.

INCOME TAXES

Tax Act

On December 22, 2017, President Trump signed the Tax Act into law. 

Among other provisions, the Tax Act lowered the corporate federal income tax 
rate from 35% to 21%, limits interest deductions outside of regulated utility 
operations, requires the normalization of excess deferred taxes associated 
with property under the average rate assumption method as a prerequisite to 
qualifying for accelerated depreciation and repealed the federal manufacturing 
deduction. The Tax Act also repealed the corporate AMT and stipulates a refund 
of 50% of remaining AMT credit carryforwards (to the extent the credits exceed 
regular tax for the year) for tax years 2018, 2019, and 2020, with all remaining 
AMT credits to be refunded in tax year 2021.

On December 22, 2017, the SEC staff issued Staff Accounting Bulletin 
(SAB) 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act, 
which provides guidance on accounting for the Tax Act’s impact. SAB 118 
provides a measurement period, which in no case should extend beyond one 
year from the Tax Act enactment date, during which a company acting in good 
faith may complete the accounting for the impacts of the Tax Act under ASC 
Topic 740. In accordance with SAB 118, a company must reflect the income tax 
effects of the Tax Act in the reporting period in which the accounting under ASC 
Topic 740 is complete. To the extent that a company’s accounting for certain 
income tax effects of the Tax Act is incomplete, a company can determine a 
reasonable estimate for those effects and record a provisional estimate in the 
financial statements in the first reporting period in which a reasonable estimate 
can be determined.

As of December 31, 2018, the accounting for the effects of the Tax Act 
was complete. During the year ended December 31, 2018, Duke Energy recorded 
the following measurement period adjustments in accordance with SAB 118:

• Additional tax expense of $23 million related to the completion of 

the analysis of Duke Energy’s existing regulatory liability related to 
deferred taxes;

• A $10 million tax benefit for the remeasurement of deferred tax 

assets and deferred tax liabilities primarily related to the guidance on 

200

bonus depreciation issued by the IRS in August 2018, affecting the 
computation of the Company’s 2017 Federal income tax liability;

• Additional tax expense of $7 million related to the portion of the deferred 

tax asset as of December 31, 2017, that represents nondeductible 
long-term incentives under the Tax Act’s limitation on the deductibility 
of executive compensation; and

• During the fourth quarter of 2018, the Company released the $76 million 
valuation allowance that it recorded in the first quarter of 2018 as a 
result of additional guidance published by the IRS that stated refundable 
AMT credits would not be subject to sequestration.

• The majority of Duke Energy’s operations are regulated and it is 

expected that the Subsidiary Registrants will ultimately pass on the 
savings associated with the amount representing the remeasurement of 
deferred tax balances related to regulated operations to customers. For 
Duke Energy’s regulated operations, where the reduction is expected to 
be returned to customers in future rates, the remeasurement has been 
deferred as a regulatory liability. During 2018, Duke Energy recorded 
an additional regulatory liability of $83 million, representing the 
revaluation of those deferred tax balances. The Subsidiary Registrants 
continue to respond to requests from regulators in various jurisdictions 
to determine the timing and magnitude of savings they will pass on to 
customers.

In addition, during 2018, Duke Energy reclassified $573 million of AMT 

credit carryforwards from noncurrent deferred tax liabilities to a current federal 
income tax receivable. In 2019, Duke Energy received a refund of $573 million 
related to AMT credit carryforwards based on the filing of Duke Energy’s 2018 
income tax return in 2019 and reclassified $286 million of AMT credits from 
noncurrent deferred tax liabilities to a current federal income tax receivable.

ITEM 9A.  CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

Management’s Annual Report on Internal Control Over Financial Reporting

Disclosure controls and procedures are controls and other procedures 
that are designed to ensure that information required to be disclosed by the 
Duke Energy Registrants in the reports they file or submit under the Exchange 
Act is recorded, processed, summarized and reported, within the time periods 
specified by the SEC rules and forms.

Disclosure controls and procedures include, without limitation, controls 

and procedures designed to provide reasonable assurance that information 
required to be disclosed by the Duke Energy Registrants in the reports they 
file or submit under the Exchange Act is accumulated and communicated to 
management, including the Chief Executive Officer and Chief Financial Officer, 
as appropriate, to allow timely decisions regarding required disclosure.
Under the supervision and with the participation of management, 
including the Chief Executive Officer and Chief Financial Officer, the Duke Energy 
Registrants have evaluated the effectiveness of their disclosure controls and 
procedures (as such term is defined in Rule 13a-15(e) and 15d-15(e) under the 
Exchange Act) as of December 31, 2019, and, based upon this evaluation, the 
Chief Executive Officer and Chief Financial Officer have concluded that these 
controls and procedures are effective in providing reasonable assurance of 
compliance.

Changes in Internal Control Over Financial Reporting

Under the supervision and with the participation of management, 
including the Chief Executive Officer and Chief Financial Officer, the Duke Energy 
Registrants have evaluated changes in internal control over financial reporting 
(as such term is defined in Rules 13a-15 and 15d-15 under the Exchange 
Act) that occurred during the fiscal quarter ended December 31, 2019, and 
have concluded no change has materially affected, or is reasonably likely to 
materially affect, internal control over financial reporting.

The Duke Energy Registrants’ management is responsible for establishing 
and maintaining an adequate system of internal control over financial reporting, 
as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). The 
Duke Energy Registrants’ internal control system was designed to provide 
reasonable assurance regarding the reliability of financial reporting and the 
preparation of financial statements for external purposes, in accordance with 
GAAP. Due to inherent limitations, internal control over financial reporting may 
not prevent or detect misstatements. Also, projections of any evaluation of 
effectiveness of the internal control over financial reporting 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 policies and procedures may 
deteriorate.

The Duke Energy Registrants’ management, including their Chief 

Executive Officer and Chief Financial Officer, has conducted an evaluation of the 
effectiveness of their internal control over financial reporting as of December 31, 
2019, based on the framework in the Internal Control – Integrated Framework 
(2013) issued by the Committee of Sponsoring Organizations of the Treadway 
Commission. Based on that evaluation, management concluded that its internal 
controls over financial reporting were effective as of December 31, 2019.
Deloitte & Touche LLP, Duke Energy’s independent registered public 
accounting firm, has issued an attestation report on the effectiveness of Duke 
Energy’s internal control over financial reporting, which is included herein. This 
report is not applicable to the Subsidiary Registrants as these companies are 
not accelerated or large accelerated filers.

PART IIREPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of  
Duke Energy Corporation

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Duke Energy Corporation and subsidiaries (the “Company”) as of December 31, 2019, based on 

criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). 
In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2019, based on criteria 
established in Internal Control - Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial 

statements as of and for the year ended December 31, 2019, of the Company and our report dated February 20, 2020, expressed an unqualified opinion on those 
financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of 
internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting. Our responsibility 
is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB 
and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the 
Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable 
assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of 
internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal 
control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a 
reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process 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. A company’s internal control over financial 
reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions 
and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial 
statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance 
with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized 
acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

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.

(2) 

Includes RSUs and performance shares (assuming the maximum payout level) granted under the Duke Energy Corporation 2015 Long-Term Incentive Plan, as well as shares that could be payable with respect to certain 
compensation deferred under the Duke Energy Corporation Executive Savings Plan (Executive Savings Plan) or the Directors’ Savings Plan.
Includes shares remaining available for issuance pursuant to stock awards under the Duke Energy Corporation 2015 Long-Term Incentive Plan.

(5)  The number of shares remaining available for future issuance under equity compensation plans not approved by security holders cannot be determined because it is based on the amount of future voluntary deferrals, if any, 

under the Executive Savings Plan and the Directors’ Savings Plan.

Under the Executive Savings Plan, participants can elect to defer a portion 

of their base salary and short-term incentive compensation. Participants also 
receive a company matching contribution in excess of the contribution limits 
prescribed by the Internal Revenue Code under the Duke Energy Retirement 
Savings Plan, which is the 401(k) plan in which employees are generally 
eligible to participate. In general, payments are made following termination of 
employment or death in the form of a lump sum or installments, as selected 
by the participant. Participants may direct the deemed investment of base 
salary deferrals, short-term incentive compensation deferrals and matching 
contributions among investment options available under the Duke Energy 
Retirement Savings Plan, including the Duke Energy Common Stock Fund. 
Participants may change their investment elections on a daily basis. Deferrals of 
equity awards are credited with earnings and losses based on the performance 

of the Duke Energy Common Stock Fund. The benefits payable under the plan 
are unfunded and subject to the claims of Duke Energy’s creditors.

Under the Directors’ Savings Plan, outside directors may elect to defer 

all or a portion of their annual compensation, generally consisting of retainers. 
Deferred amounts are credited to an unfunded account, the balance of which is 
adjusted for the performance of phantom investment options, including the Duke 
Energy Common Stock Fund, as elected by the director, and generally are paid 
when the director terminates his or her service from the Board of Directors.

Duke Energy will provide additional information that is responsive to this 

Item 12 in its definitive proxy statement or in an amendment to this Annual 
Report not later than 120 days after the end of the fiscal year covered by this 
Annual Report. That information is incorporated in this Item 12 by reference.

ITEM 13.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS AND DIRECTOR INDEPENDENCE

Duke Energy will provide information that is responsive to this Item 13 in its definitive proxy statement or in an amendment to this Annual Report not later than 

120 days after the end of the fiscal year covered by this Annual Report. That information is incorporated in this Item 13 by reference.

other services have been specifically preapproved up to fee limits. In the event 

the cost of any of these services may exceed the fee limits, the Audit Committee

by the independent accountant were approved by the Audit Committee pursuant 
to the preapproval policy.
