Corporate Profile
Hydro One Limited (TSX: H)
Safety remains our top priority
At Hydro One, safety is a core value that guides every
decision we make. In 2024, we enhanced our focus
on safety through advanced training programs and
technology. As a result, our recordable injury rate of
0.55 per 200,000 hours remains well below industry
benchmarks. But, as always, there is more to do.
We continue to build a culture where every
employee takes responsibility for their safety and
the safety of their colleagues. And we extend that
culture of safety to the communities we serve by
making sure our operations also contribute to
public safety and reliability.
A strategy for the future
To keep up with – and lead – in a rapidly evolving
energy landscape, we launched a refreshed strategy
focused on four priorities:
• Customers – Strengthen trust and improve
customer satisfaction with exceptional service.
• Growth – Expand and modernize the grid to meet
Ontario’s energy needs.
• Solutions – Drive innovation and leverage
technology to support an electrified future.
• Partnerships – Build meaningful partnerships
to develop high-impact solutions.
Over the past year, we have made meaningful
progress to advance these priorities.
We continued to serve our customers with the
utmost dedication to excellent service, and that’s
evident in the consistency of our customer service
scorecard metrics.
Customer satisfaction for residential and small
businesses increased from 87% to 88% last year,
and satisfaction scores for commercial and
industrial customers increased from 82% to 85%.
We introduced advanced analytics solutions to
improve customer service training as well an
AI-powered knowledge assistant to help frontline
staff with customer interactions.
Last year, despite a notable increase in storm days
compared to the 10-year average, we remained
steadfast in our commitment to customers, restoring
power quickly and safely. Beyond our local efforts,
we stepped in to support those in need in the wake
of severe storms across Canada and the United
States where our dedicated crews worked tirelessly
to restore power and help where needed.
At the same time, we focused on growth and
solutions that support an electrified future.
We filed an application with the Ontario Energy
Board to construct the St. Clair Transmission Line,
which will improve reliability and provide capacity
for growth in southwest Ontario.
A message from our
President and CEO
As we reflect on 2024, I am proud of Hydro One’s
journey and the progress we have made together. Our
unwavering focus on safety, customer service, growth,
innovative solutions and meaningful partnerships has
strengthened our company. I’m pleased to share our
achievements and outline how we are positioning
Hydro One for a strong and sustainable future.

David Lebeter
President and Chief Executive Officer
We completed the Chatham to Lakeshore
Transmission Line a year ahead of schedule,
and approximately $30 million under budget.
This project strengthens the reliability and capacity
of the electricity network in southwest Ontario,
supporting agri-food and manufacturing industries
and economic growth.
In northern Ontario, following extensive evaluation
and consultation by the province, we were selected
to develop a transmission line between Wawa and
Timmins. This line will support increased electricity
demand from communities, businesses and
industries, while enabling economic growth in the
advanced manufacturing and critical mineral sectors.
Last November, we broke ground on the Waasigan
Transmission Line with First Nations partners,
municipal officials and industry representatives,
marking a significant step in supporting regional
economic growth, particularly in the mining and
forestry sectors.
We could not build these new transmission
lines without strong municipal and First Nations
relationships as well as our innovative Indigenous
equity partnership model.
Our 50-50 First Nations Equity Partnership model
is an industry-leading approach that offers First
Nations the opportunity to invest in half of the equity
in the lines portion of new transmission projects
valued at more than $100 million, creating shared
economic benefits from planning and development,
all the way through to construction and operation.
We strive to build respectful, collaborative
relationships with Indigenous communities, and
we recently signed relationship agreements with
the Lac Des Milles Lac, Wauzhushk Onigum and
Long Lac #58 communities. These agreements
address community priorities and pave the way for
meaningful partnerships to connect communities
to critical infrastructure.
Through these projects and other company
purchases, we set a goal to purchase 5% of all
goods and services from Indigenous businesses by
2026. We met this target ahead of schedule for a
total of $158 million in purchases from Indigenous
businesses last year.
Delivering shareholder value
In 2024, Hydro One delivered strong shareholder
value through growth in revenues, operational
efficiencies and financial performance. Gross
revenues increased by 8.2% compared to 2023
and revenues net of purchased power rose by 3.6%.
Earnings per share grew by 6.6% to $1.93, and we
increased our quarterly dividend by 6.0% to 31.42
cents per share. In 2024, we delivered a total return
to shareholders of 14.8%, further reinforcing our
financial strength and performance. Our focus on
productivity led to $150 million in savings, while
sharing $42 million with customers through our
earnings sharing mechanism. Additionally, S&P
upgraded our long-term debt rating to “A” from
“A-” on June 10, which reflects confidence in our
performance and stability.
Looking ahead
As we move into 2025, I’m confident that Hydro
One will continue to create value for our customers,
partners, shareholders, and communities. Our
strategic focus, commitment to our values and
dedicated team position us for long-term success.
Together, we will power Ontario’s future, building
a resilient, affordable and sustainable electricity
network for generations to come.
Thank you to our employees for their dedication
and hard work, to our customers for their trust,
and to our shareholders for their ongoing support.
Sincerely,
David Lebeter

Other Segment
Hydro One's other segment consists principally of its telecommunications business, which provides telecommunications support
for the Company’s transmission and distribution businesses, as well as certain corporate activities.
The telecommunication business is carried out by Hydro One's wholly-owned subsidiary, Acronym Solutions Inc. (Acronym). In
addition to supporting Hydro One's regulated business segments, Acronym offers a comprehensive suite of Information
Communications Technology solutions within a number of categories (including: Internet & Network, Security, Voice &
Collaboration, Cloud and Managed Information Technology (IT)) that extend beyond its fibre optic network, in a competitive
commercial market. Acronym is not regulated by the OEB, however Acronym is registered with the Canadian Radio-television
and Telecommunications Commission as a non-dominant, facilities-based carrier, providing broadband telecommunications
services in Ontario with connections to Montreal, Quebec; Buffalo, New York; and Detroit, Michigan.
Hydro One's other segment also includes the deferred tax asset (DTA) which arose from the revaluation of the tax bases of
Hydro One’s assets to fair market value when the Company transitioned from the provincial payments in lieu of tax regime to the
federal tax regime at the time of the Company’s initial public offering in 2015. As the DTA is not required to be shared with
ratepayers, the Company considers it to not be part of the regulated transmission and distribution segment assets, and it is
included in the other segment. Furthermore, Hydro One's other segment also includes Aux Energy Inc., a wholly-owned
subsidiary that provides energy solutions to commercial and industrial clients, and Ontario Charging Network LP, a joint venture
that owns and operates electric vehicle fast charging stations across Ontario under the Ivy Charging Network brand, as well as
certain corporate activities, and is not rate-regulated.

Hydro One Limited | 2024 Annual Report
PRIMARY FACTORS AFFECTING RESULTS OF OPERATIONS
Transmission Revenues
Transmission revenues primarily consist of regulated transmission rates approved by the OEB which are charged based on the
monthly peak electricity demand across Hydro One’s high-voltage network. Transmission rates are designed to generate
revenues necessary to construct, upgrade, extend and support a transmission system with sufficient capacity to accommodate
maximum forecasted demand and a regulated return on the Company’s investment. Peak electricity demand is primarily
influenced by weather and economic conditions. Transmission revenues also include export revenues associated with
transmitting electricity to markets outside of Ontario as well as ancillary revenues associated with providing maintenance
services to power generators and from third-party land use.
Distribution Revenues
Distribution revenues primarily consist of regulated distribution rates approved by the OEB, as well as the recovery of purchased
power costs. Distribution rates are designed to generate revenues necessary to construct and support the local distribution
system with sufficient capacity to accommodate existing and new customer demand and a regulated return on the Company’s
investment. Accordingly, distribution revenues are influenced by distribution rates, the cost of purchased power, and the amount
of electricity the Company distributes. Distribution revenues also include ancillary distribution service revenues, such as fees
related to the joint use of Hydro One’s distribution poles by the telecommunications and cable television industries, as well as
miscellaneous revenues such as charges for late payments.
Purchased Power Costs
Purchased power costs are incurred by the distribution business and represent the cost of the electricity purchased by the
Company for delivery to customers within Hydro One’s distribution service territory. These costs are comprised of: (i) the
wholesale commodity cost of energy; (ii) the Global Adjustment, which is the difference between the guaranteed price and the
money the generators earn in the wholesale marketplace; and (iii) the wholesale market service and transmission charges levied
by the IESO. Hydro One passes on the cost of electricity that it delivers to its customers, and is therefore not exposed to
wholesale electricity commodity price risk.
OM&A
OM&A costs are incurred to support the operation and maintenance of the transmission and distribution systems, and include
other costs such as property taxes related to transmission and distribution stations and buildings, and the operation of IT
systems. Transmission OM&A costs are required to sustain the Company’s high-voltage transmission stations, lines, and rights-
of-way, and include preventive and corrective maintenance costs related to power equipment, overhead transmission lines,
transmission station sites, and forestry control to maintain safe distances between line spans and trees. Distribution OM&A costs
are required to maintain the Company’s low-voltage distribution system to provide safe and reliable electricity to the Company's
residential, small business, commercial, and industrial customers across the province. These include costs related to distribution
line clearing and forestry control to reduce power outages caused by trees, line maintenance and repair, land assessment and
remediation, as well as issuing timely and accurate bills and responding to customer inquiries.
Hydro One manages its costs through ongoing efficiency and productivity initiatives, while continuing to complete planned work
programs associated with the development and maintenance of its transmission and distribution networks.
Depreciation, Amortization and Asset Removal Costs
Depreciation and amortization costs relate primarily to the depreciation of the Company’s property, plant and equipment, and
amortization of certain intangible assets and regulatory assets. Asset removal costs consist of costs incurred to remove property,
plant and equipment where no asset retirement obligations have been recorded on the balance sheet.
Financing Charges
Financing charges relate to the Company’s financing activities and include interest expense on the Company’s long-term debt
and short-term borrowings, as well as gains and losses on interest rate swap agreements, foreign exchange or other similar
contracts, net of interest earned on short-term investments. A portion of financing charges incurred by the Company is capitalized
to the cost of property, plant and equipment associated with the periods during which such assets are under construction before
being placed in-service.

RESULTS OF OPERATIONS
Net Income
Net income attributable to common shareholders of Hydro One for the year ended December 31, 2024 of $1,156 million is $71
million, or 6.5%, higher than the prior year. Significant influences on the change in net income attributable to common
shareholders of Hydro One included:
•
higher revenues, net of purchased power,4 resulting from an increase in transmission and distribution revenues due to
OEB-approved 2024 rates, differences in regulatory adjustments recorded in each respective period, and higher energy
consumption; and
•
lower OM&A costs primarily resulting from lower work program expenditures; partially offset by
•
higher depreciation, amortization and asset removal costs primarily due to the growth in capital assets as the Company
continues to place new assets in-service;
•
higher financing charges primarily due to higher interest on long-term debt as well as higher long-term debt, partially offset
by a lower average volume of short-term notes outstanding and higher capitalized interest; and
•
higher income tax expense, adjusted for net income neutral items, primarily due to lower deductible timing differences and
higher pre-tax earnings.
While net income neutral, year-to-date results were also impacted by the cessation of the OEB-approved recovery of DTA
amounts previously shared with ratepayers (DTA Recovery Amounts) on June 30, 2023 (see section “Regulation - Deferred Tax
Asset” for further details) which resulted in a decrease in revenue, net of purchased power in the current year that has been
offset by lower income tax expense.
EPS
EPS was $1.93 for the year ended December 31, 2024, compared to EPS of $1.81 in 2023. The increase in EPS was primarily
driven by the impact of higher earnings year-over-year, as discussed above.
A discussion of management's expectations as to the Company's EPS guidance for 2023 to 2027 is contained in the Company's
press release dated February 20, 2025 under the heading “Selected Operating Highlights”. This press release is available on
SEDAR+ at www.sedarplus.com under the Company's profile and on our website at https://www.hydroone.com/investor-

Hydro One Limited | 2024 Annual Report
Transmission Revenues
Transmission revenues increased by 2.5% compared to the year ended December 31, 2023, primarily due to:
•
higher revenues resulting from OEB-approved 2024 rates; partially offset by
•
net income neutral items, including lower revenue related to the OEB-approved recovery of regulatory assets in the prior
period and the cessation of the DTA recovery period (see section “Regulation - DTA” for further details), which are offset in
OM&A and income tax expense, respectively; and
•
regulatory adjustments in the period, including a higher earnings sharing accrual.
Distribution revenues
Distribution revenues increased by 10.6% compared to the year ended December 31, 2023, primarily due to:
•
higher purchased power costs, which are fully recovered from ratepayers and thus net income neutral;
•
higher revenues resulting from OEB-approved 2024 rates;
•
regulatory adjustments in the period, including a lower earnings sharing accrual; and
•
higher energy consumption; partially offset by
•
net income neutral items, including costs associated with mutual storm assistance costs recovered from third parties which
is offset in OM&A, partially offset by lower revenues associated with the cessation of the DTA Recovery period and lower
revenue of Hydro One Remotes, which are offset in income tax expense and OM&A, respectively.
Distribution revenues, net of purchased power,5 increased by 5.3% compared to the same period in the prior year largely due to
the factors noted above, adjusted for the recovery of purchased power costs.

Transmission OM&A Costs
Transmission OM&A costs were 4.8% lower than the year ended December 31, 2023, primarily due to:
•
lower OM&A associated with the OEB-approved recovery of cost deferrals, which is offset in revenue and therefore net
income neutral;
•
lower corporate support costs; and
•
lower work program expenditures, primarily related to environmental and vegetation management programs.
Distribution OM&A Costs
Distribution OM&A costs were 5.8% lower than the year ended December 31, 2023, primarily due to:
•
lower work program expenditures, including forecast environmental expenditures provisioned in the prior year, lower
emergency restoration costs and lower spend on IT initiatives;
•
regulatory adjustments associated with the forecasted regulatory recovery of certain costs in accordance with the OEB-
approved Getting Ontario Connected Act Variance Account;
•
lower corporate support costs; and
•
net income neutral items, including lower fuel costs of Hydro One Remotes, partially offset by mutual storm assistance
costs, both of which are offset in revenue; partially offset by
•
higher allowance for doubtful accounts.
Other OM&A Costs
Other OM&A costs were 24.4% higher than the year ended December 31, 2023, including higher costs in Acronym primarily due
to higher third party service costs.
Depreciation, Amortization and Asset Removal Costs
Depreciation, amortization and asset removal costs increased by $70 million, or 7.0%, for the year ended December 31, 2024.
This increase was primarily due to growth in capital assets as the Company continues to place new assets in-service, consistent
with its ongoing capital investment program, and higher asset removal costs.

long-term debt as a result of higher average debt levels and higher weighted-average interest rates, partially offset by a lower
average volume of short-term notes outstanding and higher capitalized interest.
Income Tax Expense
Income taxes are accounted for using the asset and liability method. Current income taxes are recorded based on the income
taxes expected to be paid in respect of the current and prior years’ taxable income. Deferred income tax assets and liabilities are
recognized for the future tax consequences attributable to temporary differences between the financial statement carrying
amounts and the respective tax basis of assets and liabilities including carryforward unused tax losses and credits.
As prescribed by the regulators, the Company recovers income taxes in revenues from ratepayers based on an estimate of
current income tax expense in respect of regulated operations. The amounts of deferred income taxes related to regulated
operations, which are considered to be more likely-than-not of recovery from, or refund to, ratepayers in future periods are
recognized as deferred income tax regulatory assets or liabilities, with an offset to deferred income tax expense. Therefore, the
consolidated income tax expense or recovery for the current period is based on the total current and deferred income tax
expense or recovery, net of the regulatory accounting offset to deferred income tax expense arising from temporary differences
recoverable from or refundable to customers in the future.
Income tax expense of $181 million for the year ended December 31, 2024, compares to $178 million in 2023. The $3 million
increase in income tax expense for the year ended December 31, 2024 was primarily attributable to:
•
lower deductible timing differences compared to the prior year; and
•
higher pre-tax earnings, adjusted for the net income neutral items; partially offset by
•
net income neutral items, including the cessation of the DTA Recovery period and the OEB-approved recovery of cost
deferrals recognized as regulatory assets in prior periods, both of which are offset by a corresponding reduction in revenue
and therefore net income neutral.
The Company realized an effective tax rate (ETR) of approximately 13.4% for the year ended December 31, 2024 compared to
approximately 14.0% realized in 2023. The decrease of 0.6% was primarily attributable to the factors noted above.

Net Income - 2023 compared to 2022
Net income attributable to common shareholders of Hydro One for the year ended December 31, 2023 of $1,085 million was $35
million, or 3.3%, higher than the prior year. Significant influences on the change in net income attributable to common
shareholders included:
•
higher revenues, net of purchased power,6 resulting from:
•
OEB-approved 2023 transmission rates; and
•
higher average monthly peak demand and energy consumption; partially offset by
•
regulatory adjustments, including the recognition of conservation and demand management (CDM) revenues in
the prior year following receipt of the OEB’s Decision and Order approving Hydro One’s Joint Rate Application
(JRAP) Settlement Proposal and higher earnings sharing in the current period;
•
higher OM&A costs primarily resulting from higher work program expenditures and corporate support costs, partially offset
by a lower allowance for doubtful accounts;
•
higher depreciation, amortization and asset removal costs primarily due to gains on the disposal of fixed assets recognized
in the prior year, as well as higher depreciation resulting from the growth in capital assets as the Company continues to
place new assets in-service, consistent with its ongoing capital investment program;
•
higher financing charges attributable to higher weighted-average interest rates on long-term debt and short-term notes and
a higher volume of long-term debt; and
•
lower income tax expense primarily attributable to higher deductible timing differences compared to the prior year.
While net income neutral, the results of operations in the period are also impacted by:
•
the OEB-approved recovery of historical cost deferrals recognized as regulatory assets in prior periods which resulted in an
increase in revenue that has been offset by higher OM&A and income tax expense; and
•
the cessation of the OEB-approved recovery of DTA amounts previously shared with ratepayers on June 30, 2023 which
resulted in a decrease to revenue that had been offset by lower income tax expense.
EPS - 2023 compared to 2022
EPS was $1.81 for the year ended December 31, 2023, compared to EPS of $1.75 in 2022. The increase in EPS was primarily
driven by the impact of higher earnings year-over-year, as discussed above.

HYDRO ONE LIMITED
MANAGEMENT’S DISCUSSION AND ANALYSIS (continued)
For the years ended December 31, 2024 and 2023
1 Estimated costs are presented gross of any potential contribution from external parties.
2 This Project is part of a two-phase project, which includes the construction of a transmission station and a transmission line to meet the needs of, and is anticipated
to be largely funded by, an industrial customer. Phase 1 of the Centennial Transmission Station Project includes a new transmission station in St. Thomas and an
approximately 2 km, 230 kV double-circuit transmission line between the new transmission station and an existing transmission station in the city. This phase of the
project is anticipated to be in service by 2025. Scope and timing of the second phase, an approximately 20 km, 230 kV double-circuit transmission line from London
to St. Thomas, is currently under review.
3 The Waasigan Transmission Line Project includes construction of new transmission lines as well as station enhancements to support energization of the new lines.
The estimated cost relates to the development and construction phases of the project and the anticipated in-service date reflects the anticipated completion in 2027,
as further discussed in the section “Other Developments - Supporting Critical Transmission Infrastructure in Northwestern Ontario”.
4 The St. Clair Transmission Line Project includes the line and associated facilities and is further discussed in the section “Other Developments - Supporting Critical
Infrastructure in Southwestern Ontario”.
5 The capital cost to date relates to the development phase of the project. The scope and timing of these Southwestern Ontario transmission reinforcements are
currently under review.
6 The capital cost to date relates to the development phase of the project. The scope and timing of these Northeastern and Eastern Ontario transmission
reinforcements are currently under review. Durham Kawartha Power Line was previously referred to as the Greater Toronto Area East Line. Northeast Power Line
was previously referred to as the Hanmer to Mississagi Line. North Shore Link was previously referred to as the Mississagi to Third Line Line.
7 The IESO has recommended a target in-service date by 2030 for the Wawa to Porcupine Transmission Line.
8 Major portions of the Bruce B Switching Station Circuit Breaker Replacement were completed and placed in-service in 2025.
9 This project includes asset replacements to meet the needs of the Ontario system as well as a customer funded enhancement.
10 The coordinated project includes both an asset replacement and station expansion. The anticipated in-service dates are between 2026 to 2029.

Hydro One Limited | 2024 Annual Report
Future Capital Investments
The Company estimates future capital investments based on management’s expectations of the amount of capital expenditures
that will be required to provide transmission and distribution services that are efficient, reliable, and provide value for customers,
consistent with the OEB’s Renewed Regulatory Framework. The Company includes projects when there is a high degree of
confidence that the project will go forward and when there is a thorough estimate of the expected expenditures.
The 2025 to 2027 capital estimates differ from prior disclosures as the Company has updated its plan for current estimate of
required broadband investments, timing and pacing of future capital investments, and re-prioritization of work.
The following tables summarize Hydro One’s annual projected capital investments for 2025 to 2027 by business segment and by

2 Since the first quarter of 2022, the Minister of Energy and Electrification (formerly the Minister of Energy) (Minister) has directed the OEB to amend Hydro One
Networks’ transmission licence to require it to develop and seek approvals for eight priority transmission lines in Ontario. The future capital investments presented
do not include capital expenditures, nor development costs, associated with the following three priority Southwestern Ontario transmission line projects: Longwood
to Lakeshore Transmission Line, Second Longwood to Lakeshore Transmission Line, and Lakeshore to Windsor Transmission Line; nor the following four priority
Northeastern and Eastern Ontario transmission line projects: North Shore Link, Northeast Power Line, Durham Kawartha Power Line, and Wawa to Porcupine
Transmission Line (see section “Other Developments - Supporting Critical Transmission Infrastructure in Northeastern and Eastern Ontario”). Hydro One is currently
evaluating the scope and timing of these seven lines.
3 “Other” capital expenditures include investments in fleet, real estate, IT, and operations technology and related functions.
SUMMARY OF SOURCES AND USES OF CASH
Hydro One’s primary sources of cash flows are funds generated from operations, capital market debt issuances and bank credit
facilities that are used to satisfy Hydro One’s capital resource requirements, including the Company’s capital expenditures,
servicing and repayment of debt, and dividend payments.

Net cash from operating activities
Net cash from operating activities increased by $122 million for the year ended December 31, 2024 compared to the same
period in 2023. The increase was impacted by various factors, including the following:
•
higher pre-tax earnings; and
•
changes in regulatory account balances; partially offset by
•
increase in net working capital deficiency primarily attributable to higher accrued liabilities, lower receivables from the
IESO driven by lower Ontario Electricity Rebate from the IESO, higher cost of power payable to the IESO driven by higher
commodity rates charges, partially offset by higher prepaid expenses and higher accounts receivable balances.
Net cash from (used in) financing activities
Net cash from financing activities increased by $1,405 million for the year ended December 31, 2024, compared to the same
period of 2023. This increase was impacted by various factors, including the following:
Sources of cash
•
the Company issued $2,781 million of long-term debt in 2024, compared to $2,375 million of long-term debt issued in 2023.
•
the Company received proceeds of $2,810 million from the issuance of short-term notes in 2024, compared to $6,550
million received in 2023.

by the Company during the year ended December 31, 2024 against the prior year.
LIQUIDITY AND FINANCING STRATEGY
Short-term liquidity is provided through FFO,7 Hydro One Inc.’s commercial paper program, and the Company’s consolidated
bank credit facilities. Under the commercial paper program, Hydro One Inc. is authorized to issue up to $2,300 million in short-
term notes with a term to maturity of up to 365 days.
As at December 31, 2024, Hydro One Inc. had $200 million in commercial paper borrowings outstanding, compared to
$279 million outstanding at December 31, 2023. The Company also has committed, unsecured, and revolving credit facilities
(Operating Credit Facilities) with a total available balance of $3,300 million as at December 31, 2024. The Operating Credit
Facilities include a pricing adjustment which can increase or decrease Hydro One’s cost of funding based on its performance on
certain sustainability performance measures, which are related to Hydro One's sustainability goals. On June 1, 2024, Hydro One
increased the committed amount under the Operating Credit Facilities by $750 million and extended the maturity date from 2028
to 2029. No amounts were drawn on the Operating Credit Facilities as at December 31, 2024 or 2023. The Company may use
the Operating Credit Facilities for working capital and general corporate purposes. The short-term liquidity under the commercial
paper program, the Operating Credit Facilities, available cash on hand and anticipated levels of FFO7 are expected to be
sufficient to fund the Company’s operating requirements.
As at December 31, 2024, the Company had long-term debt outstanding in the principal amount of $17,495 million, which
included $425 million of long-term debt issued by Hydro One and $17,070 million of long-term debt issued by Hydro One Inc.
The long-term debt issued by Hydro One was issued under a previous short form base shelf prospectus. The majority of long-
term debt issued by Hydro One Inc. has been issued under its Medium-Term Note (MTN) Program, as further described below.
The Company's total long-term debt consists of notes and debentures that mature between 2025 and 2064, and as at
December 31, 2024 had a weighted-average term to maturity of approximately 13.7 years (December 31, 2023 - 13.7 years) and
a weighted-average coupon rate of 4.2% (December 31, 2023 - 4.1%).
In February 2024, Hydro One Inc. filed a short form base shelf prospectus in connection with its MTN Program, which expires in
March 2026. Upon issuance of the short form base shelf prospectus in February 2024, the Company does not qualify for the
distribution of any additional notes under the previous MTN Program prospectus that was filed in June 2022.
On August 19, 2024, Hydro One filed the Universal Base Shelf Prospectus with securities regulatory authorities in Canada. The
short form base shelf prospectus (Universal Base Shelf Prospectus) allows Hydro One to offer, from time to time in one or more
public offerings, debt, equity or other securities, or any combination thereof, during the 25-month period ending in September
2026. As at December 31, 2024, no securities have been issued under the Universal Base Shelf Prospectus.
On November 29, 2024, Hydro One Holdings Limited (HOHL) filed a short form base shelf prospectus (U.S. Debt Shelf
Prospectus) with securities regulatory authorities in Canada and the U.S. to replace a previous prospectus that would otherwise
have expired in December 2024. The U.S. Debt Shelf Prospectus, expiring in December 2026, allows HOHL to offer, from time to
time in one or more public offerings, debt securities, unconditionally guaranteed by Hydro One. As at December 31, 2024, no
securities have been issued under the U.S. Debt Shelf Prospectus.
Compliance
As at December 31, 2024, the Company was in compliance with all financial covenants and limitations associated with the
outstanding borrowings and credit facilities.
Credit Ratings
Various ratings organizations review the Company’s and Hydro One Inc.’s debt ratings from time to time. These rating
organizations may take various actions, positive or negative. The Company cannot predict what actions rating agencies may take
in the future. The failure to maintain the Company’s current credit ratings could adversely affect the Company’s financial
condition and results of operations, and a downgrade in the Company’s credit ratings could restrict the Company’s ability to
access debt capital markets and increase the Company’s cost of debt.

Effect of Interest Rates
The Company is exposed to fluctuations of interest rates as its regulated return on equity (ROE) is derived using a formulaic
approach that takes into account changes in benchmark interest rates for Government of Canada debt and the A-rated utility
corporate bond yield spread. The Company issues debt from time to time to refinance maturing debt and for general corporate
purposes. The Company is therefore exposed to fluctuations in interest rates in relation to such issuances of debt. See section
“Risk Management and Risk Factors - Risks Relating to Hydro One’s Business - Market, Financial Instrument and Credit Risk”
for more details.
Pension Plan
In 2024, Hydro One made cash contributions of $75 million to its pension plan, compared to cash contributions of $69 million in
2023. The Company also incurred $57 million of net periodic benefit credit, compared to $93 million of net periodic benefit credit
incurred in 2023.
In September 2024, Hydro One filed a triennial actuarial valuation of its pension plan as at December 31, 2023 which is effective
for 2024 to 2026. Based on this valuation, Hydro One estimates that total Company pension contributions for 2025, 2026, 2027,
2028, 2029 and 2030 are approximately $78 million, $80 million, $83 million, $86 million, $89 million, and $92 million,
respectively. Future minimum contributions beyond 2026 will be updated following the actuarial funding valuation as of December
31, 2026, which is expected to be filed by no later than September 30, 2027. Should Hydro One elect to file a valuation earlier
than required, contributions for 2025 and 2026 would also be updated, as applicable.
The Company’s pension benefits obligation is impacted by various assumptions and estimates, such as the discount rate, rate of
return on plan assets, rate of cost of living increase and mortality assumptions. A full discussion of the significant assumptions
and estimates can be found in the section “Critical Accounting Estimates - Employee Future Benefits”.

DTA
On April 8, 2021, the OEB rendered a decision approving the recovery of the DTA amounts allocated to ratepayers and included
in customer rates for the 2017 to 2021 period, plus carrying charges, over a two-year recovery period from July 1, 2021 to June
30, 2023 (DTA Recovery period). In addition, the DTA Implementation Decision required that Hydro One adjust transmission
revenue requirement and the base distribution rates beginning January 1, 2022 to eliminate any further tax savings flowing to
customers. The DTA Implementation Decision had no impact on FFO8 for the year ended December 31, 2024 (2023 - increase of
$67 million) as the DTA Recovery period ceased on June 30, 2023.
Incremental Cloud Computing Implementation Costs Deferral Account
On November 2, 2023, the OEB established an industry-wide generic deferral account, effective December 1, 2023. This account
allows rate-regulated entities, including electricity distributors and transmitters, to record cloud computing implementation costs
incurred that are incremental to amounts embedded in base rates as well as any related offsetting savings, if applicable, in a
regulatory account for future recovery subject to the approval of the OEB. On March 6, 2024, the OEB commenced a hearing
that will consider matters related to the Incremental Cloud Computing Implementation Costs deferral account, including what
type of interest rate, if any, should apply. As at December 31, 2024, the Company has recorded approximately $10 million in this
account.

cost of long-term debt and an adjustment to rate base to reflect final project expenditures and will set the revenue requirements
for the 2026 to 2029 period.
Building Broadband Faster Act, 2021
In March 2021, the Province of Ontario (Province) introduced Bill 257, Supporting Broadband and Infrastructure Expansion Act,
2021, to create a new act entitled the Building Broadband Faster Act, 2021 (BBFA) that is aimed at supporting the timely
deployment of broadband infrastructure within unserved and underserved rural Ontario communities. Bill 257 received Royal
Assent on April 12, 2021. Bill 257 amended the Ontario Energy Board Act, 1998 (OEBA) to provide the Province with regulation-
making authority regarding the development of, access to, or use of electricity infrastructure for non-electricity purposes. The
BBFA Guideline and two regulations informing the legislative changes were also published in 2021, with a third regulation on
annual wireline attachment rate for telecommunications carriers issued in December 2021. The most recent Order and Decision
from the OEB adjusts the annual wireline attachment rate to $39.14 per attacher per pole, effective January 1, 2025.
In March 2022, the Province introduced Bill 93 (Getting Ontario Connected Act, 2022). Bill 93 received Royal Assent on April 14,
2022. Bill 93 amends the BBFA to ensure that organizations that own underground utility infrastructure near a designated high-
speed internet project provide timely access to their infrastructure data, which would allow internet service providers to quickly
start work on laying down underground high-speed internet infrastructure.

Hydro One Limited | 2024 Annual Report
A regulation regarding electricity infrastructure and designated broadband projects under the OEBA (O.Reg. 410/22) came into
force on April 21, 2022. On July 7, 2022, the OEB established a deferral account for rate-regulated distributors to record
incremental costs associated with carrying out activities pertaining to designated broadband projects. In September 2022, the
Company launched its choice-based operating model to provide internet service providers with choices on how to access the
Company’s infrastructure in order to effectively execute designated broadband projects. On March 28, 2023, the Province
amended the OEBA (O.Reg. 410/22) with respect to performance timelines associated with designated broadband projects.
On August 14, 2023, the third edition of the BBFA Guideline was issued with amendments providing additional guidance to
support the implementation of legislative and regulatory requirements, including a framework to support cost sharing for pole
attachments and make-ready work.
The Company has developed and adapted an appropriate management framework that meets the government’s objectives,
including arrangements to sustain the Company’s revenues and recovery of reasonable associated costs.
On October 31, 2024, the Ministry of Infrastructure announced that it has developed a program to deliver up to $400 million in
subsidies to internet service providers (ISPs) for work associated with designated broadband projects. The program is intended
to enable ISPs to successfully and safely attach their material and equipment to the Company’s poles to bring connectivity to
rural communities as part of a designated broadband project. A portion of the subsidies will be used to reimburse Hydro One
Networks on behalf of ISPs for their share of enablement costs incurred to facilitate the program to date (see section “Related
Party Transactions”).
Affordable Energy Act, 2024 and Ontario Integrated Energy Plan
In January 2024, the Electrification and Energy Transition Panel, an advisory body to the Province, released its report outlining a
roadmap for Ontario’s transition to a clean energy economy. In October 2024, the Province released its vision for Ontario’s
energy sector, Ontario’s Affordable Energy Future, outlining key objectives to meet growing electricity demand in Ontario. This
vision is intended to help guide the Province’s first integrated energy plan, among other initiatives. In support, Bill 214, Affordable
Energy Act, 2024, was introduced and subsequently received Royal Assent on December 4, 2024. The Affordable Energy Act,
2024 amended various statutes, including the Electricity Act and the OEBA, providing a legislative framework to replace the
Province’s long-term energy plans (including the 2017 Long-Term Energy Plan), with integrated energy plans. Integrated energy
plans are expected to detail actions and policy steps to build an affordable, reliable and clean energy system over the long term.
Whereas the focus of the long-term energy plan has been primarily on the electricity system, the integrated energy plan is
intended to address all sources of energy. The amendments effected by the Affordable Energy Act, 2024 also allow the Minister,
subject to the approval of the Lieutenant Governor in Council, to issue directives to the IESO and OEB setting out
implementation requirements relating to the integrated energy plan. From October to December 2024, the Ministry of Energy and
Electrification (Ministry) ran a consultation requesting feedback to assist the Province in developing its first plan. The Province’s
first integrated energy plan is expected to be released in early 2025.
The changes made by the Affordable Energy Act, 2024 to the OEBA, among other things, also provide the Province with the
ability to make regulations specifying amendments to the Distribution System Code and the Transmission System Code in
relation to certain cost allocation and cost recovery matters relating to the construction, expansion or reinforcement of distribution
systems or transmission systems, or of connections to those systems. The changes made by the Affordable Energy Act, 2024
also allow regulations to be made exempting persons or things from provisions of the Distribution System Code and the
Transmission System Code relating to cost allocation or cost recovery, as well as alternative provisions that apply instead.

Chatham to Lakeshore Transmission Line Project
On November 24, 2022, the OEB issued its Decision and Order granting Hydro One Networks leave to construct the Chatham to
Lakeshore Transmission Line Project, with standard conditions of approval.
On April 22, 2024, CLLP was formed to own and operate the transmission line. On April 26, 2024, Hydro One Networks, on
behalf of CLLP, filed an application with the OEB requesting certain approvals, including obtaining an electricity transmission
licence and approval to sell assets related to the Chatham to Lakeshore Transmission Line Project to CLLP. On July 25, 2024,
the OEB issued its Decision and Order approving this application. Hydro One Networks maintains and operates the Chatham to
Lakeshore in accordance with an operation and management services agreement.
St. Clair Transmission Line Project
In March 2022, the Province issued an Order in Council with a directive from the Minister (formerly the Minister of Energy) to the
OEB, requiring Hydro One Networks to develop and seek approvals for the St. Clair Line, a 230 kV line from Lambton
Transmission Station to Chatham Switching Station. In response to the directive, the OEB amended Hydro One Networks’
transmission license in April 2022 to develop and seek approval for the St. Clair Transmission Line Project. On May 28, 2024,
Hydro One Networks filed a leave-to-construct application seeking OEB approval of the project. The total project is expected to
cost approximately $472 million, with $335 million attributable to transmission line work and $137 million attributable to station
costs. The project is expected to be in service by 2028. On December 10, 2024, the OEB issued its Decision and Order granting
leave to construct as requested in the application, with standard conditions of approval.
Supporting Critical Transmission Infrastructure in Northwestern Ontario
In 2013, the Province issued an Order in Council with a directive from the Minister (formerly the Minister of Energy) to the OEB,
requiring that Hydro One Networks develop and seek approvals for the Northwest Bulk Transmission Line (now the Waasigan
Transmission Line). In response to the 2013 directive, the OEB amended Hydro One Networks’ transmission license in 2014 to
allow it to develop and seek approval for the project.
On April 25, 2023, Hydro One Networks received a letter from the IESO confirming the need for reliable electricity in
Northwestern Ontario. In this letter, the IESO recommends that Phase 2 of the Waasigan Transmission Line Project, a single-
circuit 230 kV transmission line between Mackenzie Transmission Station in the Town of Atikokan and Dryden Transmission
Station in the City of Dryden, should be in-serviced as soon as practically possible following the completion of Phase 1 of the
project. This follows an IESO letter received in May 2022 in which it recommended construction of Phase 1 to proceed with an in-
service date as close to the end of 2025 as possible.
On July 31, 2023, Hydro One Networks filed a leave-to-construct application seeking OEB approval for the Waasigan
Transmission Line Project. On November 9, 2023, an Environmental Assessment was filed with the Ministry of Environment
Climate and Parks for review and approval, which incorporated both phases of the project. On April 16, 2024, the OEB issued its
Decision and Order granting leave to construct as requested in the application, with standard conditions of approval.
Hydro One Networks has agreements with nine First Nation communities providing them the opportunity to acquire a 50% equity
stake in the transmission line component of the project.
On September 26, 2024, Hydro One Networks received approval from the Ministry of Environment, Conservation and Parks on
the final Environmental Assessment Report for the Waasigan Transmission Line project. On November 22, 2024, the project
broke ground, commencing construction activities.

Hydro One Limited | 2024 Annual Report
Supporting Critical Transmission Infrastructure in Northeastern and Eastern Ontario
On July 10, 2023, the Ministry (formerly the Ministry of Energy) announced a proposal to take certain actions to facilitate the
timely development of three transmission projects across Northeastern and Eastern Ontario: North Shore Link, Northeast Power
Line, Durham Kawartha Power Line. On October 23, 2023, the Minister (formerly the Minister of Energy) directed the OEB to
amend Hydro One Networks’ licence to require it to develop and seek approvals for these three priority transmission line
projects. On November 14, 2023, further to the Minister’s Directive, the OEB amended Hydro One Networks’ electricity
transmission licence to require it to develop and seek approvals for these projects in accordance with the recommendations of
the IESO.
On August 1, 2024, the Ministry announced a proposal to declare the Wawa to Porcupine line as a priority project and designate
Hydro One Networks, in partnership with the Wabun Tribal Council, its members and Missanabie Cree First Nation, as the
transmitter. These actions are intended to facilitate the timely development of a new 230 kV, 260 km transmission line in
Northeastern Ontario from the Wawa Transformer Station (south of Wawa) to the Porcupine Transformer Station (Timmins area)
to be in service for 2030. The proposal was open for a 45 day consultation period ending September 15, 2024. On November 28,
2024, the Minister directed the OEB to amend Hydro One Networks’ transmission license to require it to develop and seek
approvals for this project. On December 23, 2024, further to the Minister’s Directive, the OEB amended Hydro One Networks’
electricity transmission licence to allow it to develop and seek approvals for this Project in accordance with the recommendations
of the IESO.
Sustainability Report
The Hydro One 2023 Sustainability Report entitled “A Better and Brighter Future For All: Enabling the Energy Transition” is
available on the Company’s website at www.hydroone.com/sustainability.
The 2023 Sustainability Report highlights Hydro One’s role in enabling the energy transition in Ontario and electrifying the
province. The report discloses the Company’s environmental, social and governance performance, along with disclosures related
to its public sustainability commitments.
Greenhouse Gas (GHG) Emissions
Following a review of Scope 1 and Scope 2 emissions over past three years, the Company has revised its target for achieving a
reduction in GHG emissions to focus on an “operations-driven” target. The Company’s target for Scope 2 emissions previously
included both indirect emissions from its delivery system (such as line losses) and operations owned or controlled by the
Company (such as energy consumption in its facilities). The Company’s Scope 2 emissions from line losses, have increased
over the period due to increased electricity demand and a changing generation mix in Ontario, which are factors beyond Hydro
One’s control. As revised, the Company will focus on reducing its “operations-driven” Scope 1 and Scope 2 GHG emissions by
30% by 2030 against a 2018 baseline and achieving net zero emissions by 2050. The Company will measure and report on
“operations-driven” Scope 1 and Scope 2 emissions, which include emissions directly related to the Company’s operations,
including energy consumption in its facilities, emissions from its fleet, and other direct operational activities. The Company has
adjusted to an "operations-driven" target because these emissions are directly in its control.

HYDRO ONE WORK FORCE
As at December 31, 2024, Hydro One had a skilled and flexible work force of approximately 7,300 (2023 - 7,000) regular
employees and 2,100 (2023 - 2,200) non-regular employees province-wide, comprising a mix of skilled trades, engineering,
professional, managerial and executive personnel. Hydro One’s regular employees are supplemented primarily by accessing a
large external labour force available through arrangements with the Company’s trade unions for contingent workers, sometimes
referred to as “hiring halls”, and also by access to contract personnel. The hiring halls offer Hydro One the ability to flexibly use
highly trained and appropriately skilled workers on a project-by-project and seasonal basis.

NON-GAAP FINANCIAL MEASURES
Hydro One uses a number of non-GAAP financial measures to assess its performance. The Company presents FFO or “funds
from operations” to reflect a measure of the Company’s cash flow, revenues, net of purchased power, to reflect the impact of
revenue on net income, and net debt to reflect a measure of the Company’s financial leverage.
Hydro One also uses financial ratios that are non-GAAP ratios such as the net debt to capitalization ratio and annualized FFO to
net debt ratio to reflect a measure of the Company’s financial leverage, and the earnings coverage ratio to reflect a measure of
liquidity.
FFO
FFO is defined as net cash from operating activities, adjusted for (i) changes in non-cash balances related to operations, (ii)
dividends paid on preferred shares, and (iii) distributions to noncontrolling interest. Management believes that FFO is helpful as a
supplemental measure of the Company’s operating cash flows as it excludes timing-related fluctuations in non-cash operating
working capital and cash flows not attributable to common shareholders. As such, management believes that FFO provides a
consistent measure of the cash generating performance of the Company’s assets.
The following table provides a reconciliation of reported GAAP results to non-GAAP results on a consolidated basis.

Revenues, Net of Purchased Power
Revenues, net of purchased power, is defined as revenues less the cost of purchased power; distribution revenues, net of
purchased power, is defined as distribution revenues less the cost of purchased power. These measures are used internally by
management to assess the impacts of revenue on net income and are considered useful because they exclude the cost of power
that is fully recovered through revenues and therefore net income neutral.
The following tables provide a reconciliation of reported GAAP revenues to non-GAAP revenues, net of purchased power, on a

The Company believes that the net debt to capitalization ratio is an important non-GAAP ratio as a measure of the Company’s
financial leverage. Net debt to capitalization ratio has been calculated as net debt, as described above, divided by net debt plus
total shareholders’ equity, but excluding any amounts related to noncontrolling interest. Management believes that the net debt to
capitalization ratio is helpful as a measure of the proportion of debt in the Company's capital structure.

Management believes that the annualized FFO to net debt ratio is helpful as a measure of the Company’s financial leverage.
Annualized FFO to net debt ratio has been calculated as FFO (see section “Non-GAAP Financial Measures - FFO”) on a rolling
twelve-month basis divided by net debt (see section “Non-GAAP Financial Measures – Net Debt”). Management believes the
annualized FFO to net debt ratio is helpful as a measure of the company’s ability to pay off its debt using the Company’s net
operating income.

RISK MANAGEMENT AND RISK FACTORS
Hydro One is subject to numerous risks and uncertainties. Critical to Hydro One’s success is the identification, management and,
to the extent possible, mitigation of these risks. Hydro One’s Enterprise Risk Management (ERM) program assists decision-
makers throughout the organization with the management of key business risks, including new and emerging risks and
opportunities.
The material risks relating to Hydro One and its business that the Company believes would be the most likely to influence an
investor’s decision to purchase Hydro One’s securities are set out in the risk factors below. These risks, if they materialize, could
have a materially adverse effect on the Company or its business, financial condition, or results of operations. This list is not a
comprehensive list of all the risks to the Company, and the actual effect of any of the risks cited below could be materially
different from what is described below. Additionally, other risks may arise or risks currently not considered material may become
material in the future.
Risks Relating to Hydro One’s Business
Regulatory Risks and Risks Relating to Hydro One’s Revenues
Risks Relating to Actual Performance Against Forecasts
The Company’s ability to recover the actual costs of providing service and earn the allowed ROE depends on the Company
achieving its forecasts established and approved in the rate-setting process. Actual costs could exceed the approved forecasts if,
for example, the Company incurs operations, maintenance, administration, capital and financing costs above those included in
the Company’s approved revenue requirement. The inability to recover any significant difference between forecast and actual
expenses and to obtain associated regulatory approvals to recover the difference could materially adversely affect the
Company’s financial condition and results of operations.
Further, the OEB approves the Company’s transmission and distribution rates based on projected electricity load and
consumption levels, among other factors. If actual load or consumption materially falls below projected levels, the Company’s
revenue, net income and cash flows for either, or both, of these businesses could be materially adversely affected.
HYDRO ONE LIMITED
MANAGEMENT’S DISCUSSION AND ANALYSIS (continued)
For the years ended December 31, 2024 and 2023
Hydro One Limited | 2024 Annual Report
27
HYDRO ONE LIMITED
MANAGEMENT’S DISCUSSION AND ANALYSIS (continued)
For the years ended December 31, 2024 and 2023
The Company’s current revenue requirements for its transmission and distribution businesses are based on cost and other
assumptions, including inflation, that may not materialize. There is no assurance that the OEB would allow rate increases
sufficient to offset unfavourable financial impacts from unanticipated changes in electricity demand or in the Company’s costs.
The Company is subject to risk of revenue loss from other factors, such as economic trends and conditions, changes in service
territory, and weather conditions that influence the demand for electricity. The Company’s overall operating results may fluctuate
substantially on a seasonal and year-to-year basis based on these trends and weather conditions. For instance, a cooler than
normal summer or warmer than normal winter can be expected to reduce demand for electricity below that forecast by the
Company, causing a decrease in the Company’s revenues, net income and cash flows as compared to the same period of the
previous year.
The Company’s load could also be negatively affected by successful CDM programs whose results exceed forecasted
expectations.
Risks Relating to Non-Rate Applications to the OEB
In addition to the matters described in the “Risks Relating to Obtaining Rate Orders” subsection below, the Company is also
subject to the risk that it will not obtain, or will not obtain in a timely manner, required regulatory approvals for other matters, such
as leave to construct applications, applications for mergers, acquisitions, amalgamations and divestitures, and environmental
approvals. Appeals of OEB decisions and/or the need to obtain required occupation rights may result in significant delays, which
could also lead to increased costs and project delays.
Decisions to acquire or divest other regulated businesses licensed by the OEB are subject to OEB approval. Accordingly, there is
the risk that such matters may not be approved, that the Company may not be selected to build new transmission as part of a
competitive process, or that unfavourable conditions will be imposed by the OEB.
Hydro One may face increased competition with other transmitters for opportunities to build new, large-scale transmission
facilities in Ontario. The Company is subject to the risk that it will not be selected to build new transmission in Ontario, which
could impair growth, disrupt operations and/or development, or have other adverse impacts.
Risks Relating to Rate-Setting Models for Transmission and Distribution
The OEB approves and periodically changes the rate-setting models and methodology for the transmission and distribution
businesses. Changes to the application type, filing requirements, rate-setting model or methodology, or revenue requirement
determination may have a material negative impact on Hydro One’s revenue and net income. For example, the OEB may in the
future decide to reduce the allowed ROE for either of these businesses, modify the formula or methodology it uses to determine
the ROE, or reduce the weighting of the equity component of the deemed capital structure. Any such reduction could reduce the
net income of the Company. Similarly, the OEB may in the future consider other utility remuneration models, and any such
change could affect Hydro One’s revenue and net income. If the OEB was to significantly change the formula for calculating ROE
or the deemed regulatory capital structure, this could result in a material adverse impact to the financial condition of the
Company.
The OEB’s Custom Incentive Rate-setting model requires that the term of a custom rate application be for multi-year periods.
There are risks associated with forecasting key inputs such as revenues, operating expenses and capital over such a long
period. For instance, if unanticipated capital expenditures arise that were not contemplated in the Company’s most recent rate
decision, the Company may be required to incur costs that may not be recoverable until a future period or not recoverable at all
in future rates. This could have a material adverse effect on the Company.
When rates are set for a multi-year period, including under a Custom Incentive Rate application, the OEB expects there to be no
further rate applications for annual updates within the multi-year period, unless it is consistent with OEB approved funding
mechanisms or there are exceptional circumstances, with the exception of the clearance of established deferral and variance
accounts. For example, the OEB does not expect to address annual rate applications for updates for cost of capital (including
ROE), working capital allowance or sales volumes. If there were an increase in interest rates over the period of a rate decision
and no corresponding changes were permitted to the Company’s revenue requirement (including cost of capital parameters),
then the result could be a decrease in the Company’s financial performance. See also “Market, Financial Instrument and Credit
Risk”.
To the extent that the OEB approves an in-service variance account for the transmission and/or distribution businesses, and
should the Company fail to meet the threshold levels of in-service capital, the OEB may reclaim a corresponding portion of the
Company’s revenues.
Risks Relating to Capital Expenditures
In order to be recoverable in rates, capital expenditures require the approval of the OEB. There can be no assurance that all
capital expenditures, including any imposed by or resulting from government or regulatory bodies, incurred by Hydro One will be
approved by the OEB. For example, capital cost overruns including those due to economic trends and conditions including
inflation; the potential imposition of duties, tariffs or trade restrictions; unexpected capital expenditures in maintaining or
improving the Company’s assets; unexpected costs as a result of proposed legislation, including that relating to the expansion of
28
Hydro One Limited | 2024 Annual Report
broadband service in Canada; may not be recoverable in transmission or distribution rates. To the extent possible, Hydro One
aims to mitigate this risk by ensuring expenditures are reasonable and prudent, and also by seeking from the regulator clear
policy direction on cost responsibility, and by obtaining pre-approval of the need for capital expenditures.
Any regulatory decision by the OEB to disallow or limit the recovery of any capital expenditures would lead to a lower-than-
expected approved revenue requirement or rate base, potential asset impairment or charges to the Company’s results of
operations, any of which could have a material adverse effect on the Company.
Risks Relating to Obtaining Rate Orders
The Company is subject to the risk that the OEB will not approve the Company’s transmission and distribution revenue
requirements requested in outstanding or future applications for rates. Rate applications for revenue requirements are subject to
the OEB’s review process, usually involving participation from intervenors and a public hearing process. There can be no
assurance that resulting decisions or rate orders issued by the OEB will permit Hydro One to recover all costs actually incurred,
including the costs of debt and income taxes, or to earn a particular ROE. A failure to obtain acceptable rate orders, or approvals
of appropriate returns on equity and the ability to recover in rates costs actually incurred, may materially adversely affect: Hydro
One’s transmission and distribution businesses, the undertaking or timing of capital expenditures, ratings assigned by credit
rating agencies, the cost and issuance of long-term debt, and other matters, any of which may in turn have a material adverse
effect on the Company. In addition, there is no assurance that the Company will receive regulatory decisions in a timely manner
and, therefore, the Company may incur costs before having an approved revenue requirement and cash flows could be
impacted. The Company is also subject to the risk that the OEB could change the regulatory treatment of certain costs which
may affect the Company’s accounting treatment of and ability to recover such costs.
Risk of Recoverability of Total Compensation Costs
Hydro One manages all of its total compensation costs, including pension and other post-employment and post-retirement
benefits (OPEBs), subject to restrictions and requirements imposed by the collective bargaining process and legislative
requirements. Any element of total compensation costs which is disallowed in whole or part by the OEB and therefore not
recoverable from customers in rates could result in costs which could be material and could decrease net income, which could
have a material adverse effect on the Company. The OEB Act prohibits Hydro One from recovering specified executive
compensation costs in its rates.
The Company provides OPEBs to qualifying employees. Hydro One currently maintains the accrual accounting method with
respect to OPEBs. If the OEB directed Hydro One to transition to a different accounting method for OPEBs or otherwise adjusted
the basis of recovery for OPEB costs, this could result in income volatility, due to an inability of the Company to book the
difference between the accrual and cash as a regulatory asset, and the Company might not be able to recover some costs. A
determination that some of the Company’s post-employment and post-retirement benefit costs are not recoverable could have a
material adverse effect on the Company.
Risks Relating to Government Action
The Province is, and is likely to remain, the largest shareholder in Hydro One Limited. The Province may be in a position of
conflict from time to time as a result of being an investor in Hydro One Limited and also being a government actor setting broad
policy objectives in the electricity industry. Government actions may not be in the interests of the Company or investors.
Governments may pass legislation or issue regulations at any time, including legislation or regulation impacting Hydro One,
which could have potential material adverse effects on Hydro One and its business. Such government actions may include, but
are not limited to, legislation, regulation, directives or shareholder action intended to reduce electricity rates, place constraints on
compensation, or affect the governance of Hydro One. Such government actions could adversely affect the Company’s financial
condition and results of operations, as well as public opinion and the Company’s reputation. Government action may also hinder
Hydro One’s ability to pursue its strategy and/or objectives.
The Province has in the past passed legislation to place limits on executive compensation at Hydro One and there is no
guarantee they may not do so in the future. Potential involvement by the Province in the Company’s executive compensation
practices may inhibit the Company’s ability to attract and retain qualified executive talent, which may also impact the Company’s
performance, strategy and/or objectives. The failure to attract and retain qualified executives could have a material adverse effect
on the Company.
Government action may also impact the Company’s credit ratings as the Company’s credit ratings reflect, in part, the rating
agencies’ assessment of government involvement in the business of Hydro One. The Company cannot predict what actions
rating agencies may take in the future, positive or negative, including in response to government action or inaction relating to or
impacting Hydro One. The failure to maintain the Company’s current credit ratings could adversely affect the Company’s financial
condition and results of operations, and a downgrade in the Company’s credit ratings could restrict the Company’s ability to
access debt capital markets and increase the Company’s cost of debt.

Indigenous Claims Risk
Some of the Company’s current and proposed transmission and distribution assets are or may be located on reserve (as defined
in the Indian Act (Canada)) (Reserve) lands, or lands over which Indigenous people have Aboriginal, treaty, or other legal rights
or claims. Some Indigenous leaders, communities, and their members have made assertions related to sovereignty and
jurisdiction over Reserve lands and traditional territories (land traditionally occupied or used by a First Nation, Métis or Inuit
group) and can assert their claims through the courts, tribunals, or direct action. These claims, and/or the settlement or resolution
of these claims could have a material adverse effect on the Company or otherwise materially adversely impact the Company’s
operations, including the development of current and future projects.
The Company’s operations and activities may give rise to the Crown having a duty to consult and potentially accommodate
Indigenous communities. Procedural aspects of the Crown's duty to consult may be delegated to the Company by the Province
or the federal government. A perceived failure by the Crown to sufficiently consult an Indigenous community, including
communities with a traditional governance model not recognized under the Indian Act (Canada), or a perceived failure by the
Company in relation to delegated consultation obligations, could result in legal challenges against the Crown and/or the
Company, including judicial review or injunction proceedings, or could potentially result in direct action against the Company by a
community or its citizens. If this occurs, it could disrupt or delay the Company’s operations and activities, including current and
future projects, and have a material adverse effect on the Company.
Risk from Transfer of Assets Located on Reserves
The transfer orders by which the Company acquired certain of Ontario Hydro’s businesses as of April 1, 1999 did not transfer title
to assets located on Reserves. The transfer of title to these assets did not occur because authorizations originally granted by the
federal government for the construction and operation of these assets on Reserves could not be transferred without required
consent. In several cases, the authorizations had either expired or had never been issued.
Currently, OEFC holds legal title to these assets and it is expected that the Company will manage them until it has obtained
permits to complete the title transfer. To occupy Reserves, the Company must have valid permits as required by the Indian Act
(Canada). For each permit, the Company may need to negotiate (an) agreement(s) with the First Nation, OEFC and any
members of the First Nation who have occupancy rights. Any such agreement(s) include provisions whereby the First Nation
consents to the issuance of a permit. For transmission assets, the Company must negotiate terms of payment. It is difficult to
predict the aggregate amount that the Company may have to pay to obtain the required agreements from First Nations. If the
Company cannot reach satisfactory agreements with the relevant First Nation to obtain federal permits, or is unable to obtain the
actual federal permits for any other reason, it may have to relocate these assets to other locations and restore the lands at a cost
that could be substantial. In a limited number of cases, it may be necessary to abandon a line and replace it with diesel
generation facilities. In either case, the costs relating to these assets could have a material adverse effect on the Company if the
costs are not recoverable in future rate orders.
Compliance with Laws and Regulations
Hydro One must comply with numerous laws and regulations affecting its business, including requirements relating to
transmission and distribution companies, environmental laws, employment laws and health and safety laws. The failure of the
Company to comply with these laws could have a material adverse effect on the Company’s business. See also “Environment
Risk” and “Health and Safety Risk”.
For example, Hydro One’s licensed transmission and distribution businesses are required to comply with the terms of their
licences, with codes and rules issued by the OEB, and with other regulatory requirements. In Ontario, the Market Rules issued
by the IESO require the Company to, among other things, comply with applicable reliability standards established by the North
American Electric Reliability Corporation (NERC) and Northeast Power Coordinating Council, Inc. (NPCC). The costs associated
with compliance with these reliability standards are expected to be recovered through rates, but there can be no assurance that
the OEB will approve the recovery of all of such costs. Failure to obtain such approvals could have a material adverse effect on
the Company.
There is the risk that new legislation, regulations, requirements or policies will be introduced in the future or that regulatory
bodies may change or modify the regulations or rules that apply to the Company. These may reduce Hydro One’s revenue, or
may require Hydro One to incur additional costs, which may or may not be recovered in future transmission and distribution
rates.
Risk of Natural and Other Unexpected Occurrences
The Company’s facilities are exposed to the effects of severe weather conditions, natural disasters, man-made events including,
but not limited to, cyber and physical terrorist type attacks, events which originate from third-party connected systems, and any
other potentially catastrophic events. The Company’s facilities may not withstand occurrences of these types in all
circumstances.
30
Hydro One Limited | 2024 Annual Report
The Company could also be subject to claims for damages from events which may be proximately connected with the
Company’s assets (for example, wildfires), claims for damages caused by its failure to transmit or distribute electricity, costs
related to ensuring its continued ability to transmit or distribute electricity or costs related to information or cyber security.
The Company does not have insurance for damage to its transmission and distribution wires, poles and towers located outside
its transmission and distribution stations resulting from these or other events. Where insurance is available for the Company’s
other assets and for damage claims and cyber security claims, such insurance coverage may have deductibles, limits and/or
exclusions that may still expose the Company to material losses. Losses from lost revenues and repair costs could be
substantial, especially for many of the Company’s facilities that are located in remote areas.
In the event that the Company is unable to recover such costs, this could have a material adverse effect on the Company.
Risk Associated with IT, Operational Technology (OT) Infrastructure, and Data Security
The Company’s ability to operate effectively in the Ontario electricity market is, in part, dependent upon it developing,
modernizing, maintaining and managing complex IT and OT systems which are employed to operate and monitor its
transmission and distribution facilities, financial and billing systems and other business systems. The Company’s increasing
reliance on information systems and expanding data networks, as well as growing volume and complexity of data, increases its
vulnerability, and exposure to information security threats. The Company’s transmission business is required to comply with
various rules and standards for transmission reliability, including mandatory standards established by the NERC and the NPCC.
These include standards relating to cyber-security and OT, which only apply to certain of the Company’s assets (generally being
those whose failure could impact the functioning of the bulk electricity system). The Company may maintain different or lower
levels of security for its assets that are not subject to these mandatory standards. The Company must also comply with various
cyber-security and privacy-related regulatory requirements under the OEB’s Ontario Cyber Security Framework and legislative
and licence requirements relating to the collection, use and disclosure of personal information and information regarding
consumers, wholesalers, generators and retailers.
Cyber-attacks or unauthorized access to corporate IT and OT systems could result in service disruptions and system failures,
which could have a material adverse effect on the Company, including as a result of a failure to provide electricity to customers.
Because it operates critical infrastructure, Hydro One may be at greater risk of cyber-attacks from third parties (including state
run or controlled parties) that could impair or incapacitate its assets. In addition, in the course of its operations, the Company
collects, uses, processes and stores information which could be exposed in the event of a cyber-security incident or other
unauthorized access or disclosure, such as information about customers, suppliers, counterparties, employees and other third
parties.
Security and system disaster recovery controls are in place; however, there can be no assurance that there will not be system
failures or security breaches or that such threats would be detected or mitigated on a timely basis. Upon occurrence and
detection, the focus would shift from prevention to isolation, remediation and recovery until the incident has been fully addressed.
Any such system failures or security breaches could have a material adverse effect on the Company.
Environment Risk
The Company is subject to extensive Canadian federal, provincial and municipal environmental regulation. Failure to comply
could subject the Company to fines or other penalties. In addition, the presence or release of hazardous or other harmful
substances could lead to claims by third parties or governmental orders requiring the Company to take specific actions such as
investigating, controlling and remediating the effects of these substances. Although Hydro One is not a large emitter of
greenhouse gases, the Company monitors its emissions to track and report on all sources, including sulphur hexafluoride or
“SF6”. The Company could be subject to costs and other risks related to emissions. Contamination of the Company’s properties
could limit its ability to sell or lease these assets in the future.
In addition, actual future environmental expenditures may vary materially from the estimates used in the calculation of the
environmental liabilities provided for in the Company’s financial statements. The Company does not have insurance coverage for
these environmental expenditures.
There is also risk associated with obtaining governmental approvals, permits, or renewals of existing approvals and permits
related to constructing or operating facilities. This may require environmental assessment or result in the imposition of conditions,
or both, which could result in delays and cost increases. Failure to obtain necessary approvals or permits could result in an
inability to complete projects which may have a material adverse effect on the Company.
The Company’s facilities are exposed to the effects of severe weather conditions and natural disasters. The Company
recognizes the risks associated with potential climate change and has developed plans to respond as appropriate. Climate
change may have the effect of shifting weather patterns and increasing the severity and frequency of extreme weather events
and natural disasters, which could impact Hydro One’s business. The Company’s facilities may not withstand occurrences of
these types in all circumstances. Notwithstanding Hydro One’s efforts to adapt and increase grid resilience, the Company’s
facilities are exposed to risks which may have an adverse effect on grid resilience. The Company could also be subject to claims
for damages from events which may be proximately connected with the Company’s assets (for example, wildfires), claims for
damages caused by its failure to transmit or distribute electricity or costs related to ensuring its continued ability to transmit or

distribute electricity. The Company does not have insurance for damage to its transmission and distribution wires, poles and
towers located outside its transmission and distribution stations resulting from these or other events. Where insurance is
available for the Company’s other assets and for damage claims, such insurance coverage may have deductibles, limits and/or
exclusions that may still expose the Company to material losses.
Losses from lost revenues and repair costs could be substantial, especially for many of the Company’s facilities that are located
in remote areas.
In the event that the Company is unable to recover such costs, this could have a material adverse effect on the Company.
Labour Relations Risk
A substantial majority of the Company’s employees are unionized and are primarily represented by either the PWU or the
Society. Over the past several years, significant effort has been expended to increase Hydro One’s flexibility to conduct
operations in a more cost-efficient manner. Although the Company has achieved improved flexibility in its collective agreements,
the Company may not be able to achieve further improvements, or at least not without increasing the risk of labour disruption.
The Company reached an agreement with the Society to renew the collective agreement, covering the period from April 1, 2023
to September 30, 2025. The Company reached a main collective agreement with the PWU, covering the period from April 1,
2023 to September 30, 2025, and a Customer Service Operations collective agreement with the PWU covering the period from
October 1, 2022 to September 30, 2025. Hydro One’s collective agreement with the CUSW covers the period from May 1, 2022
to April 30, 2026. Additionally, The Electrical Power Systems Construction Association (EPSCA) and a number of building trade
unions have agreements, to which Hydro One is bound, covering the period from May 1, 2020 to April 30, 2025.
Future negotiations with unions present the risk of a labour disruption or dispute, risk to the Company’s ability to sustain the
continued supply of electricity to customers, as well as potential risks to public safety and reputation. The Company also faces
financial risks related to its ability to negotiate collective agreements consistent with its rate orders. Any of these could have a
material adverse effect on the Company.
Risks Relating to Asset Condition, Capital Projects and Innovation
The Company continually incurs sustainment and development capital expenditures and monitors the condition of its assets to
manage the risk of equipment failures and to determine the need for and timing of major refurbishments and replacements of its
transmission and distribution infrastructure.
While traditionally a mature and stable industry, the electricity industry is facing rapid and dramatic technological change and
increasing innovation, the consequences of which could have a material adverse effect on the Company, including a reduction in
revenue.
Execution of the Company’s capital expenditure programs is partially dependent on external factors, such as OEB approvals;
environmental approvals; municipal permits; equipment outage schedules that accommodate the IESO, generators and
customers; other interrelated projects being on schedule; supply chain availability and/or cost and schedule variability for
equipment suppliers, contracted services, and consulting services; and availability of contractor resources including in relation to
workforce and equipment. Many of these external factors are beyond the Company’s control. There may also be a need for,
among other things, Environmental Assessment Act (Ontario) approvals, approvals which require public meetings, appropriate
engagement with Indigenous communities, OEB approvals of expropriation or early access to property, and other activities.
Obtaining approvals and carrying out these processes may also be impacted by opposition to the proposed site of the capital
investments. Delays in obtaining required approvals or failure to complete capital projects on a timely basis, or at all, could
materially adversely affect transmission reliability or customers’ service quality or increase maintenance costs which could have
a material adverse effect on the Company. Failure to receive approvals for projects when spending has already occurred would
result in the inability of the Company to recover the investment in the project as well as forfeit the anticipated return on
investment. The assets involved may be considered impaired and result in the write off of the value of the asset, negatively
impacting net income. If the Company is unable to carry out capital expenditure plans in a timely manner, equipment
performance may degrade, which may reduce network capacity, result in customer interruptions, compromise the reliability of the
Company’s networks or increase the costs of operating and maintaining these assets. Any of these consequences could have a
material adverse effect on the Company.
Increased competition for the development of large transmission projects and legislative changes relating to the selection of
transmitters could impact the Company’s ability to expand its existing transmission system, which may have an adverse effect on
the Company. To the extent that other parties are selected to construct, own and operate new transmission assets, the
Company’s share of Ontario’s transmission network would be reduced. Any delays in these new transmitters’ projects may
impact the Company’s own projects that it is undertaking to in-service these new transmission assets.
32
Hydro One Limited | 2024 Annual Report
Work Force Demographic Risk
By the end of 2024, approximately 8% of the Company’s employees who are members of the Company’s defined benefit and
defined contribution pension plans were eligible for retirement, and by the end of 2025, approximately 8% could be eligible.
These percentages are not evenly spread across the Company’s work force, but tend to be most significant in the most senior
levels of the Company’s staff and among management staff. During 2024, approximately 2% of the Company’s work force
(unchanged from 2% in 2023) elected to retire. Accordingly, the Company’s continued success will be tied to its ability to continue
to attract and retain sufficient qualified staff to replace the capability lost through retirements and meet the demands of the
Company’s work programs.
In addition, the Company expects the skilled labour market for its industry will remain highly competitive. Many of the Company’s
current and potential employees are sought after as they possess skills and experience that are also highly coveted by other
organizations inside and outside the electricity sector. The failure to attract, retain and deploy qualified personnel for Hydro One’s
business could have a material adverse effect on the Company.
Risk Associated with Arranging Debt Financing
The Company expects to borrow to repay its existing indebtedness and to fund a portion of capital expenditures. Hydro One Inc.
has substantial debt principal repayments coming due, including $1,150 million in 2025, $925 million in 2026 and $425 million in
2027. In addition, from time to time, the Company may draw on its syndicated bank credit facilities and/or issue short-term debt
under Hydro One Inc.’s $2,300 million commercial paper program which would mature within one year of issuance. The
Company also plans to incur continued material capital expenditures from 2024 to 2027. Cash generated from operations, after
the payment of expected dividends, will not be sufficient to fund the repayment of the Company’s existing indebtedness and
capital expenditures. The Company’s ability to arrange sufficient and cost-effective debt financing could be materially adversely
affected by numerous factors, including the regulatory environment in Ontario, the Company’s results of operations and financial
position, market conditions, the ratings assigned to its debt securities by credit rating agencies, an inability of the Company to
comply with its debt covenants, and general economic conditions (such as, among other things, changes in interest rates or
international relations and geopolitical events that could cause weaker economic conditions or increase the volatility of the capital
markets). A downgrade in the Company’s credit ratings could restrict the Company’s ability to access debt capital markets and
increase the Company’s cost of debt. Any failure or inability on the Company’s part to borrow the required amounts of debt on
satisfactory terms could impair its ability to repay maturing debt, fund capital expenditures and meet other obligations and
requirements and, as a result, could have a material adverse effect on the Company. Increasing investor interest in ESG
performance and reporting also has the potential to impact the cost and availability of the Company’s funding, as these factors
may be increasingly connected to the quality of the Company’s ESG practices and related reporting, including reports addressing
the allocation of funds and impact reporting under Hydro One’s Sustainable Financing Framework.
Market, Financial Instrument and Credit Risk
Market risk refers primarily to the risk of loss that results from changes in costs, foreign exchange rates and interest rates. The
Company is exposed to fluctuations in interest rates as its regulated ROE is derived using a formulaic approach that takes into
account anticipated interest rates. The Company issues debt from time to time to refinance maturing debt and for general
corporate purposes. The Company is therefore exposed to fluctuations in interest rates in relation to such issuances of debt.
Fluctuations in interest rates may also impact the funded position of Hydro One’s Defined Benefit Pension Plan, and associated
pension asset or liability (see also “Pension Plan Risk”). The Company is not currently exposed to material foreign exchange risk.
The OEB-approved adjustment formula for calculating ROE in a deemed regulatory capital structure of 60% debt and 40% equity
provides for increases and decreases depending on changes in benchmark interest rates for Government of Canada debt and
the A-rated utility corporate bond yield spread. For the transmission and distribution businesses, during the Custom Incentive
Rate period from 2023 to 2027, the OEB does not expect to address annual rate applications for updates to allowed ROE, so
fluctuations will have no impact to net income. The Company has interest rate exposure in 2025 and beyond associated with the
refinancing of maturing short- and long-term debt, as well as with debt issued for general corporate purposes and under the
Sustainable Financing Framework which may include debt issued in relation to growth in rate base. The Company periodically
uses interest rate swap agreements to mitigate elements of interest rate risk.
Financial assets create a risk that a counterparty will fail to discharge an obligation, causing a financial loss. Derivative financial
instruments result in exposure to credit risk, since there is a risk of counterparty default. Hydro One monitors and minimizes
credit risk through various techniques, including dealing with highly rated counterparties, limiting total exposure levels with
individual counterparties, entering into agreements which enable net settlement, and monitoring the financial condition of
counterparties. The Company does not trade in any energy derivatives. The Company is required to procure electricity on behalf
of competitive electricity retailers and certain local distribution companies for resale to their customers. The resulting
concentrations of credit risk are mitigated through the use of various security arrangements, including letters of credit, which are
incorporated into the Company’s service agreements with these retailers in accordance with the OEB’s Retail Settlement Code.
The failure to properly manage these risks could have a material adverse effect on the Company.

HYDRO ONE LIMITED
MANAGEMENT’S DISCUSSION AND ANALYSIS (continued)
For the years ended December 31, 2024 and 2023
Health and Safety Risk
Hydro One’s work environment can be inherently dangerous and there is a risk to health and safety of both the public and our
employees, as well as possible resultant operational and/or financial impacts. The Company is subject to federal and provincial
legislation and regulations relating to health and safety. Findings of a failure to comply with these requirements could result in
penalties and reputational risk, which could negatively impact the Company. Failure to comply could subject the Company to
fines or other penalties. Any regulatory decision to disallow or limit the recovery of such costs could have a material adverse
effect on the Company.
Pension Plan Risk
Hydro One has the Hydro One Defined Benefit Pension Plan in place for the majority of its employees. Contributions to the
pension plan are established by actuarial valuations which are required to be filed with the Financial Services Regulatory
Authority of Ontario on a triennial basis. The most recently filed valuation was prepared as at December 31, 2023, and was filed
in September 2024, covering a three-year period from 2024 to 2026. The next required valuation will be prepared as at
December 31, 2026 and is expected to be filed by no later than September 2027. Hydro One’s contributions to its pension plan
satisfy, and are expected to continue to satisfy, minimum funding requirements. Contributions beyond 2026 will depend on the
funded position of the plan, which is determined by investment returns, interest rates and changes in benefits and actuarial
assumptions at that time. A determination by the OEB that some of the Company’s pension expenditures are not recoverable
through rates could have a material adverse effect on the Company, and this risk may be exacerbated if the amount of required
pension contributions increases.
Hydro One currently reports and recovers its pension costs on a cash basis, and maintains the accrual method with respect to
OPEBs. Transitioning from the cash basis to an accrual method for pension costs may have material negative rate impacts for
customers or material negative impacts on the Company should recovery of costs be disallowed by the OEB.
See also “Regulatory Risks and Risks Relating to Hydro One’s Revenues - Risk of Recoverability of Total Compensation Costs”
for risks relating to recovery of pension costs.
Risk from Provincial Ownership of Transmission Corridors
The Province owns some of the corridor lands underlying the Company’s transmission system. Although the Company has the
statutory right to use these transmission corridors, the Company may be limited in its options to expand or operate its systems.
Also, other uses of the transmission corridors by third parties in conjunction with the operation of the Company’s systems, or
adjacent land use by third parties, may increase safety or environmental risks, which could have a material adverse effect on the
Company.
Litigation Risks
In the normal course of the Company’s operations, it becomes involved in, is named as a party to and is the subject of, various
legal proceedings, including regulatory proceedings, tax proceedings and legal actions, relating to actual or alleged violations of
law, common law damages claims, personal injuries, property damage, property taxes, land rights, the environment, contract
disputes, claims by former employees and claims and proceedings by Indigenous groups. The outcome of outstanding, pending
or future proceedings cannot be predicted with certainty and may be determined adversely to the Company, which could have a
material adverse effect on the Company. Even if the Company prevails in any such legal proceeding, the proceedings could be
costly and time-consuming and would divert the attention of management and key personnel from the Company’s business
operations, which could adversely affect the Company.
Transmission Assets on Third-Party Lands Risk
Some of the lands on which the Company’s transmission assets are located are owned by third parties, including the Province
and federal Crown, and are or may become subject to land claims by First Nations. The Company requires valid occupation
rights to occupy such lands (which may take the form of land use permits, easements or otherwise). If the Company does not
have valid occupational rights on third-party owned or controlled lands or has occupancy rights that are subject to expiry, it may
incur material costs to obtain or renew such occupancy rights, or if such occupancy rights cannot be renewed or obtained it may
incur material costs to remove and relocate its assets and restore the subject land. If the Company does not have valid
occupancy rights and must incur costs as a result, this could have a material adverse effect on the Company or otherwise
materially adversely impact the Company’s operations.
Reputational, Public Opinion and Political Risk
Reputation risk is the risk of negative publicity or the public’s negative perceptions towards Hydro One and the electricity industry
that may result in a detrimental impact to Hydro One’s business, operations or financial condition leading to a deterioration of
Hydro One’s reputation. Hydro One’s reputation and/or brand could be negatively impacted by changes in public opinion,
attitudes towards the Company’s privatization, failure to deliver on its customer and/or stakeholder promises, failure to comply
with mandatory reliability regulations established by the NERC and NPCC, failure to adequately respond to social issues raised
by employees, partners and/stakeholders and other external forces. Adverse reputational events or political actions could have a
material adverse effect on Hydro One’s business and prospects including, but not limited to, delays or denials of requisite
34
Hydro One Limited | 2024 Annual Report
approvals, such as denial of requested rates, and accommodations for Hydro One’s planned projects, escalated costs, legal or
regulatory action, and damage to stakeholder and community relationships. Any of these could have a material adverse impact
on Hydro One and its business, financial condition and results of operations.
Risk Associated with Outsourcing Arrangements
Hydro One has entered into outsourcing arrangements with third parties for the provision of certain IT services. If the services
are disrupted, it could have a material adverse effect on the Company. Additionally, if the outsourcing arrangement or statements
of work thereunder are terminated for any reason or expire before a new supplier is selected and fully transitioned, the Company
could be required to transfer to another service provider or insource, which could have a material adverse effect on the
Company’s business, operating results, financial condition or prospects.
Risks Associated with Acquisitions
Acquisitions include inherent risks that some or all of the expected benefits may fail to materialize, or may not occur within the
time periods anticipated, and Hydro One may incur material unexpected costs or liabilities. Realization of the anticipated benefits
would depend, in part, on the Company’s ability to successfully integrate the acquired business, including the requirement to
devote management attention and resources to integrating business practices and support functions. The failure to realize the
anticipated benefits, the diversion of management’s attention, or any delays or difficulties encountered in connection with the
integration could have an adverse effect on the Company’s business, results of operations, financial condition or cash flows.
Infectious Disease Risk
An outbreak of infectious disease, in the form of an epidemic, a pandemic, or a similar public health threat, could materially
adversely impact the Company. The extent of any such adverse impact on the Company is uncertain, and may depend on the
length and severity of any such infectious disease outbreak, any resultant government regulations, guidelines and actions, and
any related adverse changes in general economic and market conditions. Such circumstances could impact, in particular: the
Company’s operations and workforce, including security of supply, both with respect to availability and affordability, which
individually or collectively may impact the Company's ability to complete operating and capital work programs as planned,
including within scope and budget; certain financial obligations of the Company, including pension contributions and other post-
retirement benefits, as a result of changes in prevailing market conditions; the Company’s expected revenues; reductions in
overall electricity consumption and load, both short term and long term; overdue accounts and bad debt increases as a result of
changes in the ability of the Company’s customers to pay; liquidity and the Company’s ability to raise capital; the Company’s
ability to pay or increase dividends; the timing of increased rates; the Company’s ability to recover incremental costs and lost
revenues linked to the outbreak; the Company’s ability to file regulatory filings on a timely basis; timing of regulatory decisions
and the impacts those decisions may have on the Company or its ability to implement them; and customer and stakeholder
needs and expectations.
The Company also faces risks and costs associated with implementation of business continuity plans and modified work
conditions, including the risks and costs associated with maintaining or reducing its workforce, making the required resources
available to its workforce to enable essential work, including remotely where possible, and to keep its workforce healthy, as well
as risks and costs associated with recovery of normal operations. Furthermore, the Company is dependent on third party
providers for certain activities, and relies on a strong international supply chain. Any significant disruption to those providers or
the supply chain resulting from an outbreak of infectious disease could materially adversely impact the Company.
Risks Relating to the Common Shares of Hydro One Limited
Hydro One’s common shares trade on the TSX. The trading price of the common shares has in the past been, and may in the
future be, subject to significant fluctuations. These fluctuations may be caused by events or factors related or unrelated to Hydro
One’s operating performance and/or beyond its control, including: the risk factors described herein; general economic conditions
within Ontario and Canada and globally, including changes in interest rates; inflation; the potential imposition of duties, tariffs or
trade restrictions; changes in electricity prices; changes in electricity demand; weather conditions; actual or anticipated
fluctuations in Hydro One’s quarterly and annual results and the results of public companies similar to Hydro One; Hydro One’s
businesses, operations, results and prospects; Hydro One’s reputation and its relationship with the Province; the timing and
amount of dividends, if any, declared on the common shares; future issuances of common shares or other securities by Hydro
One or Hydro One Inc.; Hydro One’s relationship with its regulator; changes in government regulation, taxes, legal proceedings
or other developments; shortfalls in Hydro One’s operating results from levels forecasted by securities analysts; investor
sentiment toward energy companies in general or companies adopting ESG performance and reporting practices and the
achievement by companies of ESG targets; maintenance of acceptable credit ratings or credit quality; and the general state of
the securities markets. These and other factors may impair the development or sustainability of a liquid market for the common
shares and the ability of investors to sell common shares at an attractive price.

Risks Relating to the Company’s Relationship with the Province
Ownership and Continued Influence by the Province and Voting Power; Share Ownership Restrictions
The Province currently owns approximately 47.1% of the outstanding common shares of Hydro One. The Electricity Act, 1998
(Ontario) (Electricity Act) restricts the Province from selling voting securities of Hydro One (including common shares) of any
class or series if it would own less than 40% of the outstanding number of voting securities of that class or series after the sale
and in certain circumstances also requires the Province to take steps to maintain that level of ownership. Accordingly, the
Province is expected to continue to maintain a significant ownership interest in voting securities of Hydro One for an indefinite
period.
As a result of its significant ownership of the common shares of Hydro One, the Province has, and is expected indefinitely to
have, the ability to determine or significantly influence the outcome of shareholder votes, subject to the restrictions in the
Governance Agreement between Hydro One and the Province dated November 5, 2015 (Governance Agreement) (available on
SEDAR+ at www.sedarplus.com). Despite the terms of the Governance Agreement in which the Province has agreed to engage
in the business and affairs of the Company as an investor and not as a manager, there is a risk that the Province’s engagement
in the business and affairs of the Company as an investor will be informed by its policy objectives and may influence the conduct
of the business and affairs of the Company in ways that may not be aligned with the interests of other investors. Notwithstanding
the Governance Agreement, and in light of actions historically taken by the Province, there can be no assurance that the
Province will not take other actions in the future that could be detrimental to the interests of investors in Hydro One. See “Risks
Relating to Government Action” above.
The share ownership restrictions in the Electricity Act (Share Ownership Restrictions) and the Province’s significant ownership of
common shares of Hydro One together effectively prohibit one or more persons acting together from acquiring control of Hydro
One. They also may limit or discourage transactions involving other fundamental changes to Hydro One and the ability of other
shareholders to successfully contest the election of the directors proposed for election pursuant to the Governance Agreement.
The Share Ownership Restrictions may also discourage trading in, and may limit the market for, the common shares and other
voting securities.
Nomination of Directors and Confirmation of Chief Executive Officer (CEO) and Chair
Although director nominees (other than the CEO) are required to be independent of both the Company and the Province
pursuant to the Governance Agreement, there is a risk that the Province will nominate or confirm individuals who satisfy the
independence requirements but who it considers are disposed to support and advance its policy objectives and give
disproportionate weight to the Province’s interests in exercising their business judgment and balancing the interests of the
stakeholders of Hydro One. This, combined with the fact certain matters require a two-thirds vote of the Board, could allow the
Province to unduly influence certain Board actions such as confirmation of the Chair and confirmation of the CEO.
Board Removal Rights
Under the Governance Agreement, the Province has the right to withhold from voting in favour of all director nominees and has
the right to seek to remove and replace the entire Board, including in each case its own director nominees but excluding the CEO
and, at the Province’s discretion, the Chair. In exercising these rights in any particular circumstance, the Province is entitled to
vote in its sole interest, which may not be aligned with the interests of other stakeholders of Hydro One.
More Extensive Regulation
Although under the Governance Agreement, the Province has agreed to engage in the business and affairs of Hydro One as an
investor and not as a manager and has stated that its intention is to achieve its policy objectives through legislation and
regulation as it would with respect to any other utility operating in Ontario, there is a risk that the Province will exercise its
legislative and regulatory power to achieve policy objectives in a manner that has a material adverse effect on the Company.
See “Risks Relating to Government Action” above.
Prohibitions on Selling the Company’s Transmission or Distribution Business
The Electricity Act prohibits the Company from selling all or substantially all of the business, property or assets related to its
transmission system or distribution system that is regulated by the OEB. There is a risk that these prohibitions may limit the
ability of the Company to engage in sale transactions involving a substantial portion of either system, even where such a
transaction may otherwise be considered to provide substantial benefits to the Company and the holders of the common shares.
Future Sales of Common Shares by the Province
Although the Province has indicated that it does not intend to sell further common shares of Hydro One, the registration rights
agreement between Hydro One and the Province dated November 5, 2015 (available on SEDAR+ at www.sedarplus.com) grants
the Province the right to request that Hydro One file one or more prospectuses and take other procedural steps to facilitate
secondary offerings by the Province of the common shares of Hydro One. Future sales of common shares of Hydro One by the
Province, or the perception that such sales could occur, may materially adversely affect market prices for these common shares
36
Hydro One Limited | 2024 Annual Report
and impede Hydro One’s ability to raise capital through the issuance of additional common shares, including the number of
common shares that Hydro One may be able to sell at a particular time or the total proceeds that may be realized.
Limitations on Enforcing the Governance Agreement
The Governance Agreement includes commitments by the Province restricting the exercise of its rights as a holder of voting
securities, including with respect to the maximum number of directors that the Province may nominate and on how the Province
will vote with respect to other director nominees. Hydro One’s ability to obtain an effective remedy against the Province, if the
Province were not to comply with these commitments, is limited as a result of the Proceedings Against the Crown Act (Ontario).
This legislation provides that the remedies of injunction and specific performance are not available against the Province,
although a court may make an order declaratory of the rights of the parties, which may influence the Province’s actions. A
remedy of damages would be available to Hydro One, but damages may not be an effective remedy, depending on the nature of
the Province’s non-compliance with the Governance Agreement.
CRITICAL ACCOUNTING ESTIMATES AND JUDGMENTS
The preparation of Hydro One Consolidated Financial Statements requires the Company to make key estimates and critical
judgments that affect the reported amounts of assets, liabilities, revenues and costs, and related disclosures of contingencies.
Hydro One bases its estimates and judgments on historical experience, current conditions and various other assumptions that
are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the
carrying values of assets and liabilities, as well as identifying and assessing the Company’s accounting treatment with respect to
commitments and contingencies. Actual results may differ from these estimates and judgments. Hydro One has identified the
following critical accounting estimates and judgments used in the preparation of its Consolidated Financial Statements:
Revenues
Distribution revenues attributable to the delivery of electricity are based on OEB-approved distribution rates and are recognized
on an accrual basis and include billed and unbilled revenues. Billed revenues are based on the amount of electricity delivered as
measured from customer meters. At the end of each month, the amount of electricity delivered to customers since the date of the
last billed meter reading is estimated, and the corresponding unbilled revenue is recorded. The unbilled revenue estimate is
affected by energy consumption, weather, and changes in the composition of customer classes.
Regulatory Assets and Liabilities
Hydro One’s regulatory assets represent certain amounts receivable from electricity customers in a future period and costs that
have been deferred for accounting purposes because it is probable that they will be recovered in future rates. In addition, the
Company has recorded regulatory liabilities that generally represent amounts that are refundable to electricity customers in
future rates. The regulatory assets mainly include amounts related to the deferred income taxes, post-retirement and post-
employment non-service costs, costs related to designated broadband projects, environmental liabilities and share-based
compensation costs. The Company’s regulatory liabilities pertain primarily to deferral and variance accounts, and include
amounts related to the pension benefit liability. The regulatory assets and liabilities can be recognized for rate-setting and
financial reporting purposes only if the amounts have been approved for inclusion in the electricity rates by the OEB, or if such
approval is judged to be probable by management. The Company continually assesses the likelihood of recovery of each of its
regulatory assets and continues to believe that it is probable that the OEB will include its regulatory assets and regulatory
liabilities in setting future rates. If, at some future date, the Company judges that it is no longer probable that the OEB will include
a regulatory asset or regulatory liability in setting future rates, the respective carrying amount would be reflected in results of
operations, prospectively from the date the Company’s assessment is made.
Employee Future Benefits
Hydro One’s employee future benefits consist of pension and post-retirement and post-employment plans, and include pension,
group life insurance, health care, and long-term disability benefits provided to the Company’s current and retired employees.
Employee future benefits costs are included in Hydro One’s labour costs that are either charged to results of operations or
capitalized as part of the cost of property, plant and equipment and intangible assets. Changes in assumptions affect the benefit
obligation of the employee future benefits and the amounts that will be charged to results of operations or capitalized in future
years. The following significant assumptions and estimates are used to determine employee future benefit costs and obligations:
Weighted Average Discount Rate
The weighted average discount rate used to calculate the employee future benefits obligation is determined at each year end by
referring to the most recently available market interest rates based on “AA”-rated corporate bond yields reflecting the duration of
the applicable employee future benefit plan. The discount rate as at December 31, 2024 increased to 4.73% (2023 - 4.63%) for
pension benefits and increased to 4.75% (2023 - 4.63%) for the post-retirement and post-employment plans. The increase in the
discount rate has resulted in a corresponding decrease in employee future benefits liabilities for the pension, post-retirement and
post-employment plans for accounting purposes. The liabilities are determined by independent actuaries using the projected
benefit method prorated on service and based on assumptions that reflect management’s best estimates.

HYDRO ONE LIMITED
MANAGEMENT’S DISCUSSION AND ANALYSIS (continued)
For the years ended December 31, 2024 and 2023
Expected Rate of Return on Plan Assets
The expected long-term rate of return on pension plan assets is 7.00% as at December 31, 2024 (2023 - 7.00%). This rate is
based on the long-term return expectations at the end of 2023 and reflects the pension plan target asset mix set out in the
Statement of Investment Policies and Procedures dated November 6, 2023.
Rates of return on the respective portfolios are determined with reference to respective published market indices. The expected
rate of return on pension plan assets reflects the Company’s long-term expectations. The Company believes that this assumption
is reasonable because, with the pension plan’s balanced investment approach, the higher volatility of equity investment returns is
intended to be offset by the greater stability of fixed-income and short-term investment returns. The net result, on a long-term
basis, is a lower return than might be expected by investing in equities alone. In the short term, the pension plan can experience
fluctuations in actual rates of return.
Rate of Cost of Living Increase
The rate of cost of living increase is determined by considering differences between long-term Government of Canada nominal
bonds and real return bonds, which increased from 1.65% per annum as at December 31, 2023 to approximately 1.81% per
annum as at December 31, 2024. Based on the Bank of Canada’s commitment to keep long-term inflation between 1.00% and
3.00%, in addition to current and anticipated trends, management believes that a long-term assumption of 2.00% per annum is
reasonable for employee future benefits liability valuation purposes as at December 31, 2024 (2023 - 2.00%).
Salary Increase Assumptions
Salary increases should reflect general wage increases plus an allowance for merit and promotional increases for current
members of the Plan and should be consistent with the assumptions for consumer price inflation and real wage growth in the
economy. The merit and promotion scale was developed based on the salary increase assumption review performed in 2017.
The review considers actual salary experience from 2002 to 2016 using valuation data for all active members as at December
31, 2016, based on age and service and Hydro One’s expectation of future salary increases. Additionally, the salary scale reflects
negotiated salary increases over the contract period as well as slightly higher expected increases in the short term.
Mortality Assumptions
The Company’s employee future benefits liability is also impacted by changes in life expectancies used in mortality assumptions.
Increases in life expectancies of plan members result in increases in the employee future benefits liability. For the pension and
post-retirement plans, the mortality assumption used as at December 31, 2024 is 90% of the 2014 Canadian Pensioners
Mortality Private Sector table projected generationally using improvement Scale B (2023 - 90%). The multiplier applied to the
assumed mortality table is based on the result of a mortality experience study that was conducted in 2021. For the post-
employment plan, the mortality assumption used as at December 31, 2024 is the disability mortality table from the 2009 to 2015
Canadian Institute of Actuaries Group Long Term Disability Termination Study, which is the most recent publicly available table
that reflects Canadian experience and is commonly used by Canadian plan sponsors.
Rate of Increase in Health Care Cost Trends
The costs of post-retirement and post-employment benefits are determined at the beginning of the year and are based on
assumptions for expected claims experience and future health care cost inflation. For the post-retirement benefit plans, a study
of Hydro One’s historical per capita health care cost trend experience was conducted in 2017. The health and dental trends
reflect the results of this study as well as macroeconomic inputs such as the expected long-term rates of general inflation and
real GDP growth. The environment of high general inflation that was present in Canada in 2022 and 2023 resulted in short-term
upward pressure on the cost of certain medical services covered by Hydro One's post-retirement and post-employment benefit
plans. However, these effects were muted somewhat by plan design and government regulation. These effects in 2022 and
2023, as well as any residual effects that have occurred in 2024 have been captured though the use of actual claims experience
from 2022, 2023 and year-to-date 2024 (through November 30) in the development of the per capita claims cost assumptions
being used for the December 31, 2024 disclosures. Based on the above, Hydro One is not making any changes to its health care
trend rate assumptions for the December 31, 2024 disclosures from what was used at December 31, 2023.

Hydro One Limited | 2024 Annual Report
DISCLOSURE CONTROLS AND PROCEDURES AND INTERNAL CONTROL OVER FINANCIAL REPORTING
Disclosure controls and procedures are the processes designed to ensure that information is recorded, processed, summarized
and reported on a timely basis to the Company’s management, including its CEO and CFRO, as appropriate, to make timely
decisions regarding required disclosure in the MD&A and consolidated financial statements. At the direction of the Company’s
CEO and CFRO, management evaluated disclosure controls and procedures as of the end of the period covered by this report.
Based on that evaluation, management concluded that the Company’s disclosure controls and procedures were effective as at
December 31, 2024.
Internal control over financial reporting is designed by, or under the direction of the CEO and CFRO to provide reasonable
assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external
purposes in accordance with U.S. GAAP. The Company’s internal control over financial reporting framework includes those
policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the
transactions and disposition of the assets of the Company; (ii) provide reasonable assurance that transactions are recorded as
necessary to permit preparation of consolidated financial statements in accordance with U.S. GAAP, and that receipts and
expenditures of the Company are being made only in accordance with authorization of management and directors of the
Company; and (iii) 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 Company’s consolidated financial statements.
The Company’s management, at the direction of the CEO and CFRO, evaluated the effectiveness of the design and operation of
internal control over financial reporting based on the criteria established in the Internal Control - Integrated Framework (2013)
issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on that evaluation,
management concluded that the Company’s internal control over financial reporting was effective as at December 31, 2024.
Internal controls, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired
control objectives and due to its inherent limitations, may not prevent or detect all misrepresentations. Furthermore, the
effectiveness of internal control is affected by change and subject to the risk that internal control effectiveness may change over
time.
There were no changes in the design of the Company’s internal control over financial reporting during the three months ended
December 31, 2024 that have materially affected, or are reasonably likely to materially affect, the operation of the Company’s
internal control over financial reporting.
Management will continue to monitor its systems of internal control over reporting and disclosure and may make modifications
from time to time as considered necessary.

Net Income
Net income attributable to common shareholders for the quarter ended December 31, 2024 of $200 million is $19 million, or
10.5%, higher than the same period in the prior year. Significant influences on the change in net income included:
•
higher revenues, net of purchased power,9 resulting from an increase in transmission and distribution revenues due to
OEB-approved 2024 rates as well as differences in regulatory adjustments recorded in each respective period, partially
offset by lower average monthly peak demand; and
•
lower OM&A costs primarily resulting from lower work program expenditures; partially offset by
•
higher depreciation, amortization and asset removal costs primarily due to growth in capital assets as the Company
continues to place new assets in-service and higher amortization of regulatory assets; and
•
higher financing charges attributable to higher interest on long-term debt as well as higher long-term debt, partially offset by
lower average volume of short-term notes outstanding, and higher capitalized interest.
EPS
Basic EPS was $0.33 in the fourth quarter of 2024, compared to Basic EPS of $0.30 in the fourth quarter of 2023.
Revenues
The year-over-year decrease of $1 million, or 0.2%, in transmission revenues during the quarter primarily resulted from:
•
lower average monthly peak demand;
•
net income neutral items, including lower revenue related to the OEB-approved recovery of regulatory assets in the prior
period which is offset in OM&A; and
•
regulatory adjustments in the period, including a higher earnings sharing accrual; partially offset by
•
higher revenues resulting from OEB-approved 2024 rates.
The year-over-year increase of $124 million, or 8.5%, in distribution revenues during the quarter primarily resulted from:
•
higher purchased power costs, which are fully recovered from ratepayers and thus net income neutral;
•
regulatory adjustments, mainly attributable to a lower earnings sharing accrual in the current period;
•
higher revenues resulting from OEB-approved 2024 rates; and
•
net income neutral items, including costs associated with mutual storm assistance costs recovered from third parties,
partially offset by lower revenue of Hydro One Remotes, both of which are offset in OM&A.
Distribution revenues, net of purchased power,9 increased by 11.5% during the fourth quarter of 2024 compared to the prior year
primarily due to the factors noted above, adjusted for the recovery of purchased power costs.
OM&A Costs
The year-over-year decrease of $13 million, or 9.2%, in transmission OM&A costs during the quarter was primarily due to:
•
lower work program expenditures, primarily related to vegetation management, stations and lines maintenance work and IT
initiatives;
•
lower corporate support costs; and
•
lower OM&A associated with the OEB-approved recovery of cost deferrals which is offset in revenue and therefore net
income neutral.
The year-over-year decrease of $26 million, or 11.3%, in distribution OM&A costs during the quarter was primarily due to:
•
lower work program expenditures, including forecast environmental expenditures provisioned in the prior year, lower
emergency restoration costs and lower spend on IT initiatives;
•
lower corporate support costs; and
•
regulatory adjustments associated with the forecasted regulatory recovery of certain costs in accordance with the OEB-
approved Getting Ontario Connected Act Variance Account; partially offset by
•
net income neutral items, including costs associated with mutual storm assistance costs, partially offset by lower fuel costs
of Hydro One Remotes, both of which are offset in revenue.
The year-over-year increase of $15 million, or 57.7%, in other OM&A costs during the quarter was due to various factors,
including higher costs in Acronym primarily due to higher third party service costs.
Depreciation, Amortization and Asset Removal Costs
The increase of $37 million, or 14.9%, in depreciation, amortization and asset removal costs in the fourth quarter of 2024 was
primarily due to growth in capital assets as the Company continues to place new assets in-service, higher amortization of
regulatory assets, and higher asset removal costs.

MANAGEMENT’S DISCUSSION AND ANALYSIS (continued)
For the years ended December 31, 2024 and 2023
9 See section “Non-GAAP Financial Measures”.
42
Hydro One Limited | 2024 Annual Report
Financing Charges
The $11 million, or 7.5%, increase in financing charges for the quarter ended December 31, 2024, was primarily due to higher
interest on long-term debt as a result of higher weighted-average interest rates and higher average debt levels, partially offset by
a lower average volume of short-term notes outstanding and higher capitalized interest.
Income Tax Expense
Income tax expense for the fourth quarter of 2024 is comparable to the same period in 2023. This resulted in a realized ETR of
approximately 7.8% in the fourth quarter of 2024, compared to approximately 6.6% in the fourth quarter of the prior year.
The increase in ETR for the three months ended December 31, 2024 was primarily attributable to:
•
higher pre-tax earnings, adjusted for the net income neutral items; partially offset by
•
OEB-approved regulatory adjustments, associated with the recovery of cost deferrals recognized as regulatory assets in
prior periods, that are offset by a corresponding reduction in revenue and therefore net income neutral.
Assets Placed In-Service
The increase in transmission assets placed in-service during the fourth quarter was primarily due to:
•
investments placed in-service for the Chatham to Lakeshore Transmission Line; and
•
higher volume of line refurbishments; partially offset by
•
investments placed in-service in the prior year for the Barrie Area Transmission upgrade and grid operating and control
facilities; and
•
lower spend on minor fixed assets.
The increase in distribution assets placed in-service during the fourth quarter was primarily due to:
•
assets placed in-service for the Orleans Operation Centre;
•
higher volume of storm-related asset replacements;
•
timing of assets placed in-service for system capability reinforcement projects; and
•
higher volume of wood pole replacements; partially offset by
•
lower spend on minor fixed assets; and
•
lower volume of assets placed in-service for customer connections.
Capital Investments
The increase in transmission capital investments during the fourth quarter was primarily due to:
•
higher volume of station refurbishments and equipment replacements;
•
higher spend on spare transformer purchases;
•
investments in the St. Clair Transmission Line; and
•
higher volume of wood pole replacements; partially offset by
•
lower spend on specified equipment to support long-term projects;
•
lower spend on minor fixed assets; and
•
lower spend on customer connections.
The increase in distribution capital investments during the fourth quarter was primarily due to:
•
higher spend on storm-related asset replacements;
•
higher spend on line refurbishments and wood pole replacements;
•
investments in the Orillia Distribution Centre; and
•
investments in Ontario’s broadband initiative; partially offset by
•
lower spend on minor fixed assets.

Hydro One Limited | 2024 Annual Report
FORWARD-LOOKING STATEMENTS AND INFORMATION
The Company’s oral and written public communications, including this document, often contain “forward-looking information”
within the meaning of applicable Canadian securities laws and “forward-looking statements” within the meaning of applicable
U.S. securities laws (collectively, “forward-looking information”). Statements containing forward-looking information are made
pursuant to the “safe harbour” provisions of applicable Canadian and U.S. securities laws. Forward-looking information in this
document is based on current expectations, estimates, forecasts and projections about the Company’s business, the industry,
regulatory and economic environments in which it operates, and includes beliefs and assumptions made by the management of
the Company. Such statements include, but are not limited to, statements regarding: the Company’s transmission and distribution
rate and revenue requirement applications including the JRAP and its proposed investment plan, resulting and related decisions
as well as resulting rates, recovery and expected impacts and timing; expectations about the Company’s liquidity and capital
resources and operational requirements; sustainability goals; the Operating Credit Facilities; expectations regarding the
Company’s financing activities; the Company’s maturing debt; the Company’s ongoing and planned projects, initiatives and
expected capital investments, including expected approvals, results, costs, funding sources and in-service and completion dates;
updates to the Company’s revenue requirements for 2024 to 2027; contractual obligations and other commercial commitments;
the BBFA and expected impacts; expectations regarding the Ministry of Infrastructure’s subsidies program to ISPs and its results;
the Company’s assessment of recovery and impacts related to the OEB-established generic variance and deferral accounts;
expectations regarding the OEB hearing related to the Incremental Cloud Computing Implementation Costs deferral account;
future pension plan contributions, including estimates of total Company pension contributions beyond 2025 up to 2030; the
expected release of the Province’s first integrated energy plan in early 2025; the Company’s expectations regarding the renewal
of its collective agreements with PWU and Society in 2025; dividends; non-GAAP financial measures; internal controls over
financial reporting and disclosure; the MTN Program; the Universal Base Shelf Prospectus; the US Debt Shelf Prospectus;
recent accounting-related guidance and expected impacts; and the Company’s acquisitions and final closing adjustments. Words
such as “expect,” “anticipate,” “intend,” “attempt,” “may,” “plan,” “will,” “would,” “believe,” “seek,” “estimate,” “goal,” “aim,” “target,”
and variations of such words and similar expressions are intended to identify such forward-looking statements. These statements
are not guarantees of future performance and involve assumptions and risks and uncertainties that are difficult to predict.
Therefore, actual outcomes and results may differ materially from what is expressed, implied or forecasted in such forward-
looking statements. Hydro One does not intend, and it disclaims any obligation, to update any forward-looking statements,
except as required by law.
These forward-looking statements are based on a variety of factors and assumptions including, but not limited to, the following:
no unforeseen changes in the legislative and operating framework for Ontario’s electricity market or for Hydro One specifically;
favourable decisions from the OEB and other regulatory bodies concerning outstanding and future rate and other applications; no
unexpected delays in obtaining required regulatory approvals; no unforeseen changes in rate orders or rate setting
methodologies for the Company’s distribution and transmission businesses; no unfavourable changes in environmental
regulation; continued use of U.S. GAAP; a stable regulatory environment; no significant changes to the Company's current credit
ratings; no unforeseen impacts of new accounting pronouncements; no changes to expectations regarding electricity
consumption; no unforeseen changes to economic and market conditions; completion of operating and capital projects that have
been deferred; and no significant event occurring outside the ordinary course of business. These assumptions are based on
information currently available to the Company, including information obtained from third-party sources. Actual results may differ
materially from those predicted by such forward-looking statements. While Hydro One does not know what impact any of these
differences may have, the Company’s business, results of operations, financial condition and credit stability may be materially
adversely affected if any such differences occur. Factors that could cause actual results or outcomes to differ materially from the
results expressed or implied by forward-looking statements include, among other things:
•
regulatory risks and risks relating to Hydro One’s revenues, including risks relating to actual performance against forecasts,
competition with other transmitters and other applications to the OEB, the rate-setting models for transmission and
distribution, the recoverability of capital expenditures, obtaining rate orders or recoverability of total compensation costs;
•
risks associated with the Province’s share ownership of Hydro One and other relationships with the Province, including
potential conflicts of interest that may arise between Hydro One, the Province and related parties, risks associated with the
Province’s exercise of further legislative and regulatory powers, risks relating to the ability of the Company to attract and
retain qualified executive talent or the risk of a credit rating downgrade for the Company and its impact on the Company’s
funding and liquidity;
•
risks relating to the location of the Company’s assets on Reserve lands, that the company’s operations and activities may
give rise to the Crown’s duty to consult and potentially accommodate Indigenous communities, and the risk that Hydro One
may incur significant costs associated with transferring assets located on Reserves;
•
the risk that the Company may be unable to comply with regulatory and legislative requirements or that the Company may
incur additional costs for compliance that are not recoverable through rates;
•
the risk of exposure of the Company’s facilities to the effects of severe weather conditions, natural disasters, man-made
events or other unexpected occurrences for which the Company is uninsured or for which the Company could be subject to
claims for damage;
•
risks associated with information system security and maintaining complex IT and operational technology (OT) system
infrastructure, including system failures or risks of cyber-attacks or unauthorized access to corporate IT and OT systems;

•
the risk of non-compliance with environmental regulations and inability to recover environmental expenditures in rate
applications and the risk that assumptions that form the basis of the Company’s recorded environmental liabilities and related
regulatory assets may change;
•
the risk of labour disputes and inability to negotiate or renew appropriate collective agreements on acceptable terms
consistent with the Company’s rate decisions;
•
the risk that the Company may not be able to execute plans for capital projects necessary to maintain the performance of the
Company’s assets or to carry out projects in a timely manner or the risk of increased competition for the development of large
transmission projects or legislative changes affecting the selection of transmitters;
•
risks associated with asset condition, capital projects and innovation, including public opposition to or delays or denials of the
requisite approvals and accommodations for the Company’s planned projects;
•
risks related to the Company’s work force demographic and its potential inability to attract and retain qualified personnel;
•
the risk that the Company is not able to arrange sufficient cost-effective financing to repay maturing debt and to fund capital
expenditures, the risk of a downgrade in the Company’s credit ratings or risks associated with investor interest in ESG
performance and reporting;
•
risks associated with fluctuations in interest rates and failure to manage exposure to credit and financial instrument risk;
•
risks associated with economic uncertainty and financial market volatility;
•
the risk of failure to mitigate significant health and safety risks;
•
the risk of not being able to recover the Company’s pension expenditures in future rates and uncertainty regarding the future
regulatory treatment of pension, other post-employment benefits and post-retirement benefits costs;
•
the impact of the ownership by the Province of lands underlying the Company’s transmission system;
•
the risk associated with legal proceedings that could be costly, time-consuming or divert the attention of management and key
personnel from the Company’s business operations;
•
the impact if the Company does not have valid occupational rights on third-party owned or controlled lands and the risks
associated with occupational rights of the Company that may be subject to expiry;
•
risks relating to adverse reputational events or political actions relating to Hydro One and the electricity industry;
•
the potential that Hydro One may incur significant expenses to replace functions currently outsourced if agreements are
terminated or expire before a new service provider is selected;
•
risks relating to acquisitions, including the failure to realize the anticipated benefits of such transactions at all, or within the
time periods anticipated, and unexpected costs incurred in relation thereto;
•
risks relating to an outbreak of infectious disease;
•
the inability to continue to prepare financial statements using U.S. GAAP; and
•
the risk related to the impact of any new accounting pronouncements.

HYDRO ONE LIMITED
MANAGEMENT’S DISCUSSION AND ANALYSIS (continued)
For the years ended December 31, 2024 and 2023
46
Hydro One Limited | 2024 Annual Report
The Consolidated Financial Statements, Management’s Discussion and Analysis (MD&A) and related financial information have
been prepared by the management of Hydro One Limited (Hydro One or the Company). Management is responsible for the
integrity, consistency and reliability of all such information presented. The Consolidated Financial Statements for the year ended
December 31, 2024 and accompanying notes thereto (together, the Consolidated Financial Statements) have been prepared in
accordance with United States (U.S.) generally accepted accounting principles (GAAP) and applicable securities legislation. The
MD&A has been prepared in accordance with National Instrument 51-102.
The preparation of the Consolidated Financial Statements and information in the MD&A involves the use of estimates and
assumptions based on management’s judgment, particularly when transactions affecting the current accounting period cannot be
finalized with certainty until future periods. Estimates and assumptions are based on historical experience, current conditions and
various other assumptions believed to be reasonable in the circumstances, with critical analysis of the significant accounting
policies followed by the Company as described in Note 2 to the Consolidated Financial Statements. The preparation of the
Consolidated Financial Statements and the MD&A includes information regarding the estimated impact of future events and
transactions. The MD&A also includes information regarding sources of liquidity and capital resources, operating trends, risks
and uncertainties. Actual results in the future may differ materially from the present assessment of this information because
future events and circumstances may not occur as expected.
Management is responsible for establishing and maintaining adequate disclosure controls and procedures and internal control
over financial reporting as described in the annual MD&A. Management evaluated the effectiveness of the design and operation
of disclosure controls and procedures, and internal control over financial reporting based on the framework and criteria
established in the Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the
Treadway Commission (COSO). Based on that evaluation, management concluded that the Company’s internal control over
financial reporting was effective at a reasonable level of assurance as at December 31, 2024. As required, the results of that
evaluation were reported to the Audit Committee of the Hydro One Board of Directors.
The Consolidated Financial Statements have been audited by KPMG LLP, an independent registered public accounting firm
appointed by the shareholders of the Company. The external auditors’ responsibility is to express their opinion on whether the
Consolidated Financial Statements are fairly presented in all material respects in conformity with U.S. generally accepted
accounting principles. The Report of Independent Registered Public Accounting Firm outlines the scope of their examination and
their opinion.
The Hydro One Board of Directors, through its Audit Committee, is responsible for ensuring that management fulfills its
responsibilities for financial reporting and internal control over financial reporting and disclosure. The Audit Committee of Hydro
One met periodically with management, the internal auditors and the external auditors to satisfy itself that each group had
properly discharged its respective responsibility with respect to the Consolidated Financial Statements before recommending
approval by the Board of Directors. The external auditors had direct and full access to the Audit Committee, with and without the
presence of management, to discuss their audit findings.

HYDRO ONE LIMITED
MANAGEMENT'S REPORT
Hydro One Limited | 2024 Annual Report
47
To the Shareholders and Board of Directors of Hydro One Limited:
Opinion on the Consolidated Financial Statements
We have audited the accompanying consolidated balance sheets of Hydro One Limited (the Company) as of December 31, 2024
and 2023, the related consolidated statements of operations and comprehensive income, changes in equity, and cash flows for
each of the years in the two-year period ended December 31, 2024, and the related notes (collectively, the consolidated financial
statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of
the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the years in the
two-year period ended December 31, 2024, in conformity with U.S. generally accepted accounting principles.
Basis for Opinion
These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an
opinion on these consolidated 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 consolidated 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 consolidated 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 consolidated 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 consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial
statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or
disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or
complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated
financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate
opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Evaluation of regulatory assets and liabilities and the impact of rate regulation on the consolidated financial statements
As discussed in Note 2 to the consolidated financial statements, the Company accounts for its regulated operations in
accordance with Financial Accounting Standards Board Accounting Standard Codification Topic 980, Regulated Operations (ASC
980). Under ASC 980, the actions of the Company’s regulator may result in the recognition of revenue and costs in time periods
that are different than non-rate-regulated enterprises. When this occurs, the Company records incurred and allowed costs that it
has assessed are probable of recovery in future electricity rates as regulatory assets or property, plant and equipment.
Obligations imposed or probable to be imposed by the regulator to refund previously collected revenue or expenditure of revenue
collected from customers on future costs are recorded as regulatory liabilities. As disclosed in Note 12 to the consolidated
financial statements, as of December 31, 2024, the Company’s regulatory assets were $3,545 million and regulatory liabilities
were $1,598 million.
We identified the evaluation of regulatory assets and liabilities and the impact of rate regulation as a critical audit matter.
Accounting for regulated operations under ASC 980 affects multiple financial statement accounts and disclosures in the
Company’s consolidated financial statements. Assessing the accounting for regulated operations requires industry knowledge
and significant auditor judgment due to interpretations of regulatory decisions and judgments involved in evaluating the
Company’s assessment of the probability associated with recovery of regulatory assets and imposition of regulatory liabilities.
The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and
implementation and tested the operating effectiveness of certain internal controls over the Company’s regulatory accounting
process. This included controls over the evaluation of the probability of (1) the recovery in future rates of costs deferred as
regulatory assets, and (2) a refund of previously collected revenue or expenditure of revenue collected from customers on future
costs that should be reported as regulatory liabilities, and controls over the monitoring and evaluation of regulatory developments
that may affect the probability of recovering costs in future rates or imposing of regulatory liabilities. We evaluated the Company’s
assessment of the probability of recovery of the carrying amount for a selection of regulatory assets and for the imposition of a
HYDRO ONE LIMITED
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
48
Hydro One Limited | 2024 Annual Report
selection of regulatory liabilities, through consideration of selected regulatory proceedings, decisions and accounting orders. For
a selection of regulatory proceedings, decisions and accounting orders, we read the Company’s assessment and interpretations.
For a selection of regulatory assets and liabilities, we recalculated the amounts recorded based on methodologies approved by
the regulator and agreed the data used in the calculations to the Company’s underlying books and records. We compared the
amounts calculated by the Company to the amounts recorded in the consolidated financial statements.

DESCRIPTION OF THE BUSINESS
Hydro One Limited (Hydro One or the Company) was incorporated on August 31, 2015, under the Business Corporations Act
(Ontario). On October 31, 2015, the Company acquired Hydro One Inc., a company previously wholly-owned by the Province of
Ontario (Province). As at December 31, 2024, the Province held approximately 47.1% (2023 - 47.1%) of the common shares of
Hydro One. The businesses of Hydro One are comprised of the following three segments:
•
The Transmission segment owns and operates Hydro One’s transmission system which transmits high voltage electricity
across the province, interconnecting local distribution companies and certain large directly connected industrial customers
throughout the Ontario electricity grid. The transmission business consists of the transmission system operated by Hydro One
Inc.’s rate-regulated subsidiaries, Hydro One Networks Inc. (Hydro One Networks), Hydro One Sault Ste. Marie LP
(HOSSM), and Chatham x Lakeshore Limited Partnership (CLLP), as well as an approximate 66% interest in B2M Limited
Partnership (B2M LP) and an approximate 55% interest in Niagara Reinforcement Limited Partnership (NRLP).
•
The Distribution segment owns and operates Hydro One’s distribution system which delivers electricity to end customers and
certain other municipal electricity distributors within Ontario. The distribution business consists of the distribution systems
operated by Hydro One Inc.'s rate-regulated subsidiaries, Hydro One Networks and Hydro One Remote Communities Inc.
(Hydro One Remotes).
•
The Other segment consists principally of Hydro One’s telecommunications business, which provides telecommunications
support for the Company’s transmission and distribution businesses, as well as certain corporate activities. The
telecommunications business is carried out by Hydro One's wholly-owned subsidiary, Acronym Solutions Inc. (Acronym). In
addition to supporting Hydro One's regulated business segments, Acronym offers a comprehensive suite of Information
Communications Technology solutions. Hydro One's other segment also includes the deferred tax asset (DTA) which arose
from the revaluation of the tax bases of Hydro One’s assets to fair market value when the Company transitioned from the
provincial payments in lieu of tax regime to the federal tax regime at the time of the Company’s initial public offering in 2015.
As this DTA is not required to be shared with ratepayers, the Company considers it to not be part of the regulated
transmission and distribution segment assets and is included in the other segment. Furthermore, Hydro One's other segment
also includes Aux Energy Inc., a wholly-owned subsidiary that provides energy solutions to commercial and industrial clients,
and Ontario Charging Network LP, a joint venture that owns and operates electric vehicle fast charging stations across
Ontario under the Ivy Charging Network brand, as well as certain corporate activities, and is not rate-regulated.
Rate Setting
Transmission
On August 5, 2021 Hydro One Networks filed a custom joint rate application (JRAP) for distribution and transmission revenue
requirements for the 2023 to 2027 period. On November 29, 2022 the OEB issued a Decision and Order (JRAP Decision)
approving Hydro One Networks' transmission revenue requirement of $1,952 million for 2023, $2,073 million for 2024,
$2,168 million for 2025, $2,277 million for 2026 and $2,362 million for 2027. Revenue requirements presented for 2024 to 2027
do not reflect the actual or expected updates resulting from the annual application process with the regulator to reflect Ontario
Energy Board (OEB) inflation factors.
On July 31, 2019, B2M LP filed a transmission rate application for the 2020 to 2024 period. On January 16, 2020, the OEB
approved the 2020 base revenue requirement of $33 million, and a revenue cap escalator index for 2021 to 2024. On May 23,
2024, Hydro One Networks, on behalf of B2M LP, submitted B2M LP’s five-year transmission revenue requirement application for
the 2025 to 2029 period. On November 21, 2024, the OEB issued a Decision and Order approving B2M LP’s five-year revenue
requirement application, which includes a 2025 base revenue requirement of $38 million. Under the agreed-upon revenue
requirement framework, there is no longer a requirement for B2M LP to file annual update applications with the OEB throughout
the rate term, except for a one-time update in 2025. This update will reflect B2M LP’s actual cost of long-term debt and will set
the revenue requirements for the 2026 to 2029 period.
On October 13, 2016, the OEB issued a Decision and Order for Hydro One Inc’s Mergers, Amalgamations, Acquisitions and
Divestitures of HOSSM, including the approval of a 10-year deferred rebasing period for the 2017 to 2026 period.
On July 12, 2024, Hydro One Networks, on behalf of CLLP, submitted CLLP’s five-year transmission revenue requirement
application for the 2025 to 2029 period. On December 17, 2024, the OEB issued a Decision and Order approving CLLP’s
revenue requirement application, which includes a 2025 base revenue requirement of $17 million, effective January 1, 2025.
Under the agreed-upon revenue requirement framework, there is no longer a requirement for CLLP to file annual update
applications with the OEB throughout the rate term, except for a one-time update in 2025. This update will reflect CLLP’s actual
cost of long-term debt and an adjustment to rate base to reflect final project expenditures and will set the revenue requirements
for the 2026 to 2029 period.

SIGNIFICANT ACCOUNTING POLICIES
Basis of Consolidation and Presentation
These consolidated financial statements (Consolidated Financial Statements) include the accounts of the Company and its
subsidiaries. Inter-company transactions and balances have been eliminated.
Basis of Accounting
These Consolidated Financial Statements are prepared and presented in accordance with United States (U.S.) generally
accepted accounting principles (GAAP) and in Canadian dollars.
Use of Management Estimates
The preparation of financial statements requires management to make estimates and assumptions that affect the reported
amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues, expenses, gains
and losses during the reporting periods. Management evaluates these estimates on an ongoing basis based upon historical
experience, current conditions, and assumptions believed to be reasonable at the time the assumptions are made, with any
adjustments being recognized in results of operations in the period they arise. Significant estimates relate to unbilled revenues,
regulatory assets and regulatory liabilities, pension benefits, and post-retirement and post-employment benefits. Actual results
may differ significantly from these estimates.
Regulatory Accounting
The OEB has the general power to include or exclude revenues, costs, gains or losses in the rates of a specific period, resulting
in a change in the timing of accounting recognition from that which would have been applied in an unregulated company. Such
change in timing involves the application of rate-regulated accounting in accordance with Financial Accounting Standards Board
(FASB) Accounting Standard Codification (Codification) Topic 980, Regulated Operations, within the Company's regulated
business, giving rise to the recognition of regulatory assets and liabilities. The Company’s regulatory assets represent certain
amounts receivable from electricity customers in a future period and costs that have been deferred for accounting purposes
because it is probable that they will be recovered in future rates. In addition, the Company has recorded regulatory liabilities that
generally represent amounts that are refundable to electricity customers in future rates. The Company continually assesses the
likelihood of recovery of each of its regulatory assets and continues to believe that it is probable that the OEB will include its
regulatory assets and regulatory liabilities in setting future rates. If, at some future date, the Company judges that it is no longer
probable that the OEB will include a regulatory asset or regulatory liability in setting future rates, the respective carrying amount
would be reflected in results of operations, prospectively from the date the Company’s assessment is made.
Cash and Cash Equivalents
Cash and cash equivalents include cash and short-term investments with an original maturity of three months or less.

Revenue Recognition
Transmission revenues predominantly consist of transmission tariffs, which are collected through OEB-approved uniform
transmission rates (UTRs) which are applied against the monthly peak demand for electricity across Hydro One's high-voltage
network. OEB-approved UTRs are based on an approved revenue requirement that includes a rate of return. The transmission
tariffs are designed to recover revenues necessary to support the Company's transmission system with sufficient capacity to
accommodate the maximum expected demand which is influenced by weather and economic conditions. Transmission revenues
are recognized as electricity is transmitted and delivered to customers.
Distribution revenues attributable to the delivery of electricity are based on OEB-approved distribution rates and are recognized
on an accrual basis and include billed and unbilled revenues. Billed revenues are based on the amount of electricity delivered as
measured from customer meters. At the end of each month, the amount of electricity delivered to customers since the date of the
last billed meter reading is estimated, and the corresponding unbilled revenue is recorded. The unbilled revenue estimate is
affected by energy consumption, weather, and changes in the composition of customer classes.
Revenues also include amounts related to sales of other services and equipment. Such revenue is recognized as services are
rendered or as equipment is delivered. Revenues are recorded net of indirect taxes.
Accounts Receivable and Allowance for Doubtful Accounts
Billed accounts receivable are recorded at the invoiced amount, net of allowance for doubtful accounts. Unbilled accounts
receivable are recorded at their estimated value, net of allowance for doubtful accounts. Overdue amounts related to regulated
billings bear interest at OEB-approved rates. The allowance for doubtful accounts reflects the Company’s current lifetime
expected credit losses (CECL) for all accounts receivable balances. The Company estimates the CECL by applying internally
developed loss rates to all outstanding receivable balances by aging category on an undiscounted basis. Loss rates applied to
the accounts receivable balances are based on historical overdue balances, customer payments and write-offs, which may be
further supplemented from time to time to reflect management's best estimate of the loss. Accounts receivable are written-off
against the allowance when they are deemed uncollectible. The allowance for doubtful accounts is affected by changes in
volume, prices and economic conditions.
Noncontrolling interest
Noncontrolling interest represents the portion of equity ownership in subsidiaries that is not attributable to shareholders of Hydro
One. Noncontrolling interest is initially recorded at fair value and subsequently the amount is adjusted for the proportionate share
of net income or net loss and other comprehensive income (OCI) or other comprehensive loss (OCL) attributable to the
noncontrolling interest and any dividends or distributions paid to the noncontrolling interest.
If a transaction results in the acquisition of all, or part, of a noncontrolling interest in a subsidiary, the acquisition of the
noncontrolling interest is accounted for as an equity transaction. No gain or loss is recognized in consolidated net income or net
loss or OCI or OCL as a result of changes in the noncontrolling interest, unless a change results in the loss of control by the
Company.
Income Taxes
Income taxes are accounted for using the asset and liability method. Current tax assets and liabilities are recognized based on
the taxes refundable or payable on the current and prior year’s taxable income. Current and deferred income taxes are computed
based on the tax rates and tax laws enacted as at the balance sheet date. Tax benefits associated with income tax positions are
recorded only when the more-likely-than-not recognition threshold is satisfied and are measured at the largest amount of benefit
that has a greater than 50% likelihood of being realized upon settlement. Management evaluates each position based solely on
the technical merits and facts and circumstances of the position, assuming the position will be examined by a taxing authority
having full knowledge of all relevant information. Significant management judgment is required to determine recognition
thresholds and the related amount of tax benefits to be recognized in the Consolidated Financial Statements. Management re-
evaluates tax positions each period using new information about recognition or measurement as it becomes available.
Deferred Income Taxes
Deferred income tax assets and deferred income tax liabilities are recognized on all temporary differences between the tax
bases and carrying amounts of assets and liabilities, including the carryforward of unused tax credits and tax losses to the extent
that it is more-likely-than-not that these deductions, credits, and losses can be utilized. Deferred income tax assets and deferred
income tax liabilities are measured at the tax rates that are expected to apply in the period when the asset is realized or the
liability is settled, based on the tax rates and tax laws that have been enacted as at the balance sheet date.
Deferred income taxes associated with the Company’s regulated operations which are considered to be more-likely-than-not to
be recoverable or refunded in future regulated rates charged to customers are recognized as deferred income tax regulatory
assets and deferred income tax regulatory liabilities with an offset to deferred income tax expense.
Investment tax credits are recorded as a reduction of the related expenses or income tax expense in the current or future period
to the extent it is more likely than not that the credits can be utilized.

Hydro One Limited | 2024 Annual Report
Management reassesses the deferred income tax assets at each balance sheet date and reduces the amount to the extent that it
is more likely than not that the deferred income tax asset will not be realized. Previously unrecognized deferred income tax
assets are reassessed at each balance sheet date and are recognized to the extent that it has become more likely than not that
the tax benefit will be realized.
Property, Plant and Equipment
Property, plant and equipment is recorded at original cost, net of customer contributions, and any accumulated impairment
losses. The cost of additions, including betterments and replacement asset components, is included on the consolidated balance
sheets as property, plant and equipment.
The original cost of property, plant and equipment includes direct materials, direct labour (including employee benefits),
contracted services, attributable capitalized financing costs, asset retirement costs, and direct and indirect overheads that are
related to the capital project or program. Indirect overheads include a portion of corporate costs such as finance, treasury, human
resources, and information technology. Overhead costs, including corporate functions and field services costs, are capitalized on
a fully allocated basis.
Property, plant and equipment in service consists of transmission, distribution, communication, and administration and service
assets, as well as land easements. Property, plant and equipment also includes future use assets, such as land, major
components and spare parts, as well as capitalized project development costs associated with deferred capital projects.
Transmission
Transmission assets include assets used for the transmission of high-voltage electricity, such as transmission lines, support
structures, foundations, insulators, connecting hardware and grounding systems, as well as assets used to step up the voltage of
electricity from generating stations for transmission and to step down voltages for distribution, including transformers, circuit
breakers and switches.
Distribution
Distribution assets include assets related to the distribution of low-voltage electricity, including lines, poles, switches,
transformers, protective devices and metering systems.
Communication
Communication assets include fibre optic and microwave radio systems, optical ground wire, towers, telephone equipment and
associated buildings.
Administration and Service
Administration and service assets include administrative buildings, personal computers, transport and work equipment, tools and
other minor assets.
Easements
Easements include a statutory easement for the use of transmission corridor and related abutting lands pursuant to Part IX.1 of
the Electricity Act, 1998 (Ontario) (Electricity Act), as well as other land rights for occupation.
Intangible Assets
Intangible assets separately acquired or internally developed are measured on initial recognition at cost, which comprises
purchased software, direct labour (including employee benefits), consulting, engineering, overheads and attributable capitalized
financing charges. Following initial recognition, intangible assets are carried at cost, net of any accumulated amortization and
accumulated impairment losses. The Company’s intangible assets primarily represent major computer applications.
Capitalized Financing Costs
Capitalized financing costs represent interest costs attributable to the construction of property, plant and equipment or
development of intangible assets. The financing cost of attributable borrowed funds is capitalized as part of the acquisition cost
of such assets. The capitalized financing costs are a reduction of financing charges recognized in the consolidated statements of
operations and comprehensive income. Capitalized financing costs are calculated using the Company’s weighted average
effective cost of debt.
Construction and Development in Progress
Construction and development in progress consists of the capitalized cost of constructed assets that are not yet complete and
which have not yet been placed in service.

Depreciation and Amortization
The cost of property, plant and equipment and intangible assets is depreciated or amortized on a straight-line basis based on the
estimated remaining service life of each asset category, except for transport and work equipment, which is depreciated on a
declining balance basis.
The Company periodically initiates an external independent review of its property, plant and equipment and intangible asset
depreciation and amortization rates, as required by the OEB. Any changes arising from such a review are implemented on a
remaining service life basis, consistent with their inclusion in electricity rates. The most recent reviews resulted in changes to
rates effective January 1, 2023 for Hydro One Networks’ distribution and transmission businesses. A summary of average service
lives and depreciation and amortization rates as at December 31, 2024 for the various classes of assets is included below:

In accordance with group depreciation practices, the original cost of property, plant and equipment, or major components thereof,
and intangible assets that are normally retired, is charged to accumulated depreciation, with no gain or loss being reflected in
results of operations. Where a disposition of property, plant and equipment occurs through sale, a gain or loss is calculated
based on proceeds and such gain or loss is included in depreciation expense.
Acquisitions and Goodwill
The Company accounts for business acquisitions using the acquisition method of accounting and, accordingly, the assets and
liabilities of the acquired entities are primarily measured at their estimated fair value at the date of acquisition. Costs associated
with pending acquisitions are expensed as incurred. Goodwill represents the cost of acquired companies that is in excess of the
fair value of the net identifiable assets acquired at the acquisition date. Goodwill is not included in rate base.
Goodwill is evaluated for impairment on an annual basis, or more frequently if circumstances require. The Company performs a
qualitative assessment to determine whether it is more likely than not that the fair value of the applicable reporting unit is greater
than its carrying amount, no further testing is required. If the Company determines, as a result of its qualitative assessment, that
it is more likely than not that the fair value of the applicable reporting unit is less than its carrying amount, a quantitative goodwill
impairment assessment is performed. The quantitative assessment compares the fair value of the applicable reporting unit to its
carrying amount, including goodwill. If the fair value of goodwill is less than the carrying amount, an impairment loss is recorded
as a reduction to goodwill and as a charge to results of operations.
Based on the assessment performed as at September 30, 2024 and with no significant events since, the Company has
concluded that goodwill was not impaired as at December 31, 2024.
Long-Lived Asset Impairment
When circumstances indicate the carrying value of long-lived assets may not be recoverable, the Company evaluates whether
the carrying value of such assets, excluding goodwill, has been impaired. For such long-lived assets, the Company evaluates
whether impairment may exist by estimating future undiscounted cash flows expected to result from the use and eventual
disposition of the asset. When alternative courses of action to recover the carrying amount of a long-lived asset are under
consideration, a probability-weighted approach is used to develop estimates of future undiscounted cash flows. If the carrying
value of the long-lived asset is not recoverable based on the estimated future undiscounted cash flows, an impairment loss is
recorded, measured as the excess of the carrying value of the asset over its fair value. As a result, the asset’s carrying value is
adjusted to its estimated fair value.
Within its regulated business, the carrying costs of most of Hydro One’s long-lived assets are included in rate base where they
earn an OEB-approved rate of return. Asset carrying values and the related return are recovered through approved rates. As a
result, such assets are only tested for impairment in the event that the OEB disallows recovery, in whole or in part, or if such a
disallowance is judged to be probable. Hydro One regularly monitors the assets of its unregulated subsidiary Acronym for
indications of impairment.
Management assesses the fair value of such long-lived assets using commonly accepted techniques. Techniques used to
determine fair value include, but are not limited to, the use of recent third-party comparable sales for reference and internally
developed discounted cash flow analysis. Significant changes in market conditions, changes to the condition of an asset, or a
change in management’s intent to utilize the asset are generally viewed by management as triggering events to reassess the
cash flows related to these long-lived assets. As at December 31, 2024 and 2023, no asset impairment had been recorded for
assets within either the Company’s regulated or unregulated businesses.

Hydro One Limited | 2024 Annual Report
Costs of Arranging Debt Financing
For financial liabilities classified as other than held-for-trading, the Company defers the external transaction costs related to
obtaining financing and presents such amounts net of related debt on the consolidated balance sheets. Deferred issuance costs
are amortized over the contractual life of the related debt on an effective-interest basis and the amortization is included within
financing charges in the consolidated statements of operations and comprehensive income. Transaction costs for items classified
as held-for-trading are expensed immediately.
Financial Assets and Liabilities
All financial assets and liabilities are classified into one of the following five categories: held-to-maturity; loans and receivables;
held-for-trading; other liabilities; or available-for-sale. Financial assets and liabilities classified as held-for-trading are measured
at fair value. All other financial assets and liabilities are measured at amortized cost. Accounts receivable and amounts due from
related parties are classified as loans and receivables. The Company considers the carrying amounts of accounts receivable and
amounts due from related parties to be reasonable estimates of fair value because of the short time to maturity of these
instruments. The Company estimates the CECL for all accounts receivable balances, which are recognized as adjustments to the
allowance for doubtful accounts. Accounts receivable are written-off against the allowance when they are deemed uncollectible.
All financial instrument transactions are recorded at trade date.
The Company determines the classification of its financial assets and liabilities at the date of initial recognition. The Company
designates certain of its financial assets and liabilities to be held at fair value, when it is consistent with the Company’s risk
management policy disclosed in Note 17 - Fair Value of Financial Instruments and Risk Management.
Derivative Instruments and Hedge Accounting
The Company closely monitors the risks associated with changes in interest rates on its operations and, where appropriate, uses
various instruments to hedge these risks. Certain of these derivative instruments qualify for hedge accounting and are
designated as accounting hedges, while others either do not qualify as hedges or have not been designated as hedges
(hereinafter referred to as undesignated contracts) as they are part of economic hedging relationships.
The accounting guidance for derivative instruments requires the recognition of all derivative instruments not identified as meeting
the normal purchase and sale exemption as either assets or liabilities recorded at fair value on the consolidated balance sheets.
For derivative instruments that qualify for hedge accounting, the Company may elect to designate such derivative instruments as
either cash flow hedges or fair value hedges. The Company offsets fair value amounts recognized on its consolidated balance
sheets related to derivative instruments executed with the same counterparty under the same master netting agreement.
For derivative instruments that qualify for hedge accounting, and which are designated as cash flow hedges, any unrealized gain
or loss, net of tax, is recorded as a component of accumulated OCI (AOCI) or accumulated OCL (AOCL). Amounts in AOCI or
AOCL are reclassified to results of operations in the same period or periods during which the hedged transaction affects results
of operations and presented in the same line item as the earnings effect of the hedged item. Any gains or losses on the
derivative instrument that represent hedge components excluded from the assessment of effectiveness are recognized in the
same line item of the consolidated statements of operations as the hedged item. For fair value hedges, changes in fair value of
both the derivative instrument and the underlying hedged exposure are recognized in the consolidated statements of operations
and comprehensive income (loss) in the current period. The gain or loss on the derivative instrument is included in the same line
item as the offsetting gain or loss on the hedged item in the consolidated statements of operations and comprehensive income
(loss). The changes in fair value of the undesignated derivative instruments are reflected in results of operations.
Embedded derivative instruments are separated from their host contracts and are carried at fair value on the consolidated
balance sheets when: (a) the economic characteristics and risks of the embedded derivative are not clearly and closely related to
the economic characteristics and risks of the host contract; (b) the hybrid instrument is not measured at fair value, with changes
in fair value recognized in results of operations each period; and (c) the embedded derivative itself meets the definition of a
derivative. The Company does not engage in derivative trading or speculative activities and had no embedded derivatives that
required bifurcation as at December 31, 2024, or 2023.
Hydro One periodically develops hedging strategies taking into account risk management objectives. At the inception of a
hedging relationship where the Company has elected to apply hedge accounting, Hydro One formally documents the relationship
between the hedged item and the hedging instrument, the related risk management objective, the nature of the specific risk
exposure being hedged, and the method for assessing the effectiveness of the hedging relationship. The Company also
assesses, both at the inception of the hedge and on a quarterly basis, whether the hedging instruments are effective in offsetting
changes in fair values or cash flows of the hedged items.

Employee Future Benefits
Employee future benefits provided by Hydro One include pension, post-retirement and post-employment benefits. The costs of
the Company’s pension, post-retirement and post-employment benefit plans are recorded over the periods during which
employees render service.
The Company recognizes the funded status of its defined benefit pension plan (Pension Plan) and its post-retirement and post-
employment plans on its consolidated balance sheets and subsequently recognizes the changes in funded status at the end of
each reporting year. Defined benefit pension, post-retirement and post-employment plans are considered to be underfunded
when the projected benefit obligation (PBO) exceeds the fair value of the plan assets. Liabilities are recognized on the
consolidated balance sheets for any net underfunded PBO. The net underfunded PBO may be disclosed as a current liability,
long-term liability, or both. The current portion is the amount by which the actuarial present value of benefits included in the
benefit obligation payable in the next 12 months exceeds the fair value of plan assets. If the fair value of plan assets exceeds the
PBO of the plan, an asset is recognized equal to the net overfunded PBO. The post-retirement and post-employment benefit
plans are unfunded because there are no related plan assets.
Hydro One recognizes its contributions to the defined contribution pension plan (DC Plan) as pension expense, with a portion
being capitalized as part of labour costs included in capital expenditures. The expensed amount is included in operation,
maintenance and administration (OM&A) costs in the consolidated statements of operations and comprehensive income.
Defined Benefit Pension
Defined benefit pension costs are recorded on an accrual basis for financial reporting purposes. Pension costs are actuarially
determined using the projected benefit method prorated on service and are based on assumptions that reflect management’s
best estimate of the effect of future events, including future compensation increases. Past service costs from plan amendments
and all actuarial gains and losses are amortized on a straight-line basis over the expected average remaining service period of
active employees in the plan, or over the estimated remaining life expectancy of inactive employees in the plan. Pension plan
assets, consisting primarily of listed and unlisted equity securities, marketable and private debt, corporate and government debt
securities as well as unlisted real estate and unlisted infrastructure investments, are recorded at fair value at the end of each
year. Hydro One records a regulatory asset or regulatory liability equal to the net underfunded or overfunded PBO for its pension
plan. Defined benefit pension costs are attributed to labour costs on a cash basis and a portion directly related to acquisition and
development of capital assets is capitalized as part of the cost of property, plant and equipment and intangible assets. The
remaining defined benefit pension costs are charged to results of operations (OM&A costs).
Post-retirement and Post-employment Benefits
Post-retirement and post-employment benefits are recorded and included in rates on an accrual basis. Costs are determined by
independent actuaries using the projected benefit method prorated on service and based on assumptions that reflect
management’s best estimates. For post-retirement benefits, past service costs from plan amendments are amortized to results of
operations based on the expected average remaining service period.
For post-retirement benefits, all actuarial gains or actuarial losses are deferred using the “corridor” approach. The amount
calculated above the “corridor” is amortized to results of operations on a straight-line basis over the expected average remaining
service life of active employees in the plan or over the remaining life expectancy of inactive employees in the plan. The post-
retirement benefit obligation is remeasured to its fair value at each year end, based on an annual actuarial report, with an offset
to the associated regulatory account, to the extent of the remeasurement adjustment.
The actuarial gains and actuarial losses on post-employment obligations that are incurred during the year are recognized
immediately to results of operations. The post-employment benefit obligation is remeasured to its fair value at each year end
based on an annual actuarial report, with an offset to the associated regulatory account, to the extent of the remeasurement
adjustment.
All post-retirement and post-employment benefit costs are attributed to labour costs and are either charged to results of
operations (OM&A costs) or capitalized as part of the cost of property, plant and equipment and intangible assets (applies to the
service cost component of benefit cost) and to regulatory assets for all other components of the benefit cost, consistent with their
inclusion in OEB-approved rates.
Stock-Based Compensation
Share Grant Plans
Hydro One measures share grant plans based on fair value of share grants as estimated based on the grant date common share
price. The costs are recognized in the financial statements using the graded-vesting attribution method for share grant plans that
have both a performance condition and a service condition. The Company records a regulatory asset equal to the accrued costs
of share grant plans recognized in each period. Costs are transferred from the regulatory asset to labour costs at the time the
share grants vest and are recovered in rates. Forfeitures are recognized as they occur.

Hydro One Limited | 2024 Annual Report
Deferred Share Unit (DSU) Plans
The Company records the liabilities associated with its Directors’ and Management DSU Plans at fair value at each reporting
date until settlement, recognizing compensation expense over the vesting period on a straight-line basis. The fair value of the
DSU liability is based on the Company’s common share closing price at the end of each reporting period.
Society of United Professionals (Society) Restricted Share Unit (RSU) Plan
The Company measures its Society RSU plan based on fair value of share grants as estimated based on the grant date common
share price. The costs are recognized over the vesting period using the straight-line attribution method. The Company records a
regulatory asset equal to the accrued costs of the Society RSU plan recognized in each period. Costs are transferred from the
regulatory asset to labour costs at the time the share grants vest and are issued and recovered in rates. Forfeitures are
recognized as they occur.
Long-term Incentive Plan (LTIP)
The Company measures the awards issued under its LTIP at fair value based on the grant date common share price. The fair
value of liability-classified awards is based on the Company’s common share closing price at the end of each reporting period.
The related compensation expense is recognized over the vesting period on a straight-line basis. Forfeitures are recognized as
they occur.
Loss Contingencies
Hydro One is involved in certain legal and environmental matters that arise in the normal course of business. In the preparation
of its Consolidated Financial Statements, management makes judgments regarding the future outcome of contingent events and
records a loss for a contingency based on its best estimate when it is determined that such loss is probable and the amount of
the loss can be reasonably estimated. Where the loss amount is recoverable in future rates, a regulatory asset is also recorded.
When a range estimate for the probable loss exists and no amount within the range is a better estimate than any other amount,
the Company records a loss at the minimum amount within the range.
Management regularly reviews current information available to determine whether recorded provisions should be adjusted and
whether new provisions are required. Estimating probable losses may require analysis of multiple forecasts and scenarios that
often depend on judgments about potential actions by third parties, such as federal, provincial and local courts or regulators.
Contingent liabilities are often resolved over long periods of time. Amounts recorded in the Consolidated Financial Statements
may differ from the actual outcome once the contingency is resolved. Such differences could have a material impact on future
results of operations, financial position and cash flows of the Company.
Provisions are based upon current estimates and are subject to greater uncertainty where the projection period is lengthy. A
significant upward or downward trend in the number of claims filed, the nature of the alleged injuries, and the average cost of
resolving each claim could change the estimated provision, as could any substantial adverse or favourable verdict at trial. A
federal or provincial legislative outcome or structured settlement could also change the estimated liability. Legal fees are
expensed as incurred.
Environmental Liabilities
Environmental liabilities are recorded in respect of past contamination when it is determined that future environmental
remediation expenditures are probable under existing statute or regulation and the amount of the future expenditures can be
reasonably estimated. Hydro One records a liability for the estimated future expenditures associated with contaminated land
assessment and remediation (LAR) and for the phase-out and destruction of polychlorinated biphenyl (PCB)-contaminated
mineral oil removed from electrical equipment, based on the present value of these estimated future expenditures. The Company
determines the present value with a discount rate that produces an amount at which the environmental liabilities could be settled
in an arm’s length transaction with a third party. To the extent that the Company anticipates that the future expenditures will
continue to be recoverable in future rates, an offsetting regulatory asset has been recorded to reflect the anticipated amount of
future recovery of these environmental expenditures from customers. Hydro One reviews its estimates of future environmental
expenditures annually, or more frequently if there are indications that circumstances have changed. Estimate changes are
accounted for prospectively.
Asset Retirement Obligations
Asset retirement obligations are recorded for legal obligations associated with the future removal and disposal of long-lived
assets. Such obligations may result from the acquisition, construction, development and/or normal use of the asset. Conditional
asset retirement obligations are recorded when there is a legal obligation to perform a future asset retirement activity but where
the timing and/or method of settlement are conditional on a future event that may or may not be within the control of the
Company. In such a case, the obligation to perform the asset retirement activity is unconditional even though uncertainty exists
about the timing and/or method of settlement. This uncertainty is incorporated in the fair value measurement of the obligation.
When recording an asset retirement obligation, the present value of the estimated future expenditures required to complete the
asset retirement activity is recorded in the period in which the obligation is incurred, if a reasonable estimate can be made. In

general, the present value of the estimated future expenditures is added to the carrying amount of the associated asset and the
resulting asset retirement cost is depreciated over the estimated useful life of the asset. The present value is determined with a
discount rate that equates to the Company’s credit-adjusted risk-free rate. Where an asset is no longer in service when an asset
retirement obligation is recorded, the asset retirement cost is recorded in results of operations.
Leases
At the commencement date of a lease, the minimum lease payments are discounted and recognized as a lease obligation.
Discount rates used correspond to the Company's incremental borrowing rates. Renewal options are assessed for their likelihood
of being exercised and are included in the measurement of the lease obligation when it is reasonably certain they will be
exercised. The Company does not recognize leases with a term of less than 12 months. A corresponding Right-of-Use (ROU)
asset is recognized at the commencement date of a lease. The ROU asset is measured as the lease obligation adjusted for any
lease payments made and/or any lease incentives and initial direct costs incurred. ROU assets are included in other long-term
assets, and corresponding lease obligations are included in other current liabilities and other long-term liabilities on the
consolidated balance sheets.
Subsequent to the commencement date, the lease expense recognized at each reporting period is the total remaining lease
payments over the remaining lease term. Lease obligations are measured as the present value of the remaining unpaid lease
payments using the discount rate established at commencement date. The amortization of the ROU assets is calculated as the
difference between the lease expense and the accretion of interest, which is calculated using the effective interest method.
Lease modifications and impairments are assessed at each reporting period to assess the need for a remeasurement of the
lease obligations or ROU assets.

INCOME TAXES
As a rate regulated utility company, the Company recovers income taxes from its ratepayers based on estimated current income
tax expense in respect of its regulated business. The amounts of deferred income taxes related to regulated operations which
are considered to be more likely-than-not to be recoverable from, or refundable to, ratepayers in future periods are recognized as
deferred income tax regulatory assets or deferred income tax regulatory liabilities, with an offset to deferred income tax recovery
or deferred income tax expense, respectively. The Company’s consolidated income tax expense or income tax recovery for the
period includes all current and deferred income tax expenses for the period net of the regulated accounting offset to deferred
income tax expense arising from temporary differences to be recovered from, or refunded to, customers in future rates. Thus, the
Company’s income tax expense or income tax recovery differs from the amount that would have been recorded using the
combined Canadian federal and Ontario statutory income tax rate.
The reconciliation between the statutory and the effective tax rates is provided as follows:

Deferred Income Tax Assets and Liabilities
Deferred income tax assets and deferred income tax liabilities reflect the future income tax consequences attributable to
temporary differences between the tax bases and the financial statement carrying amounts of the assets and liabilities including
the carry forward amounts of tax losses and tax credits. Deferred income tax assets and deferred income tax liabilities
attributable to the Company’s regulated business are recognized with a corresponding offset in deferred income tax regulatory
assets and deferred income tax liabilities to reflect the anticipated recovery or repayment of these balances in the future
electricity rates. As at December 31, 2024 and 2023, deferred income tax assets and deferred income tax liabilities consisted of

Deferred Income Tax Regulatory Asset and Liability
Deferred income taxes are recognized on temporary differences between the carrying amount of assets and liabilities in the
financial statements and the corresponding tax bases used in the computation of taxable income. The Company has recognized
regulatory assets and regulatory liabilities that correspond to deferred income taxes that flow through the rate-setting process. In
the absence of rate-regulated accounting, the Company’s income tax expense would have been recognized using the liability
method and there would be no regulatory accounts established for income taxes to be recovered through future rates.
Post-Retirement and Post-Employment Benefits - Non-Service Cost
Hydro One has recorded a regulatory asset relating to the future recovery of its post-retirement and post-employment benefits
other than service costs. The regulatory asset includes the applicable tax impact to reflect taxes payable. Prior to adoption of
ASU 2017-07 in 2018, these amounts were capitalized to property, plant and equipment and intangible assets. In 2018 and 2019,
the OEB approved the regulatory asset for Hydro One Networks’ transmission business and distribution business, respectively.
As part of Hydro One Networks' 2020 to 2022 Transmission Decision, the OEB concluded that the non-service cost component
of Hydro One's OPEB costs shall be recognized as OM&A for both its transmission and distribution businesses. Furthermore,
Hydro One Networks Distribution continued to record the non-service cost component of OPEBs in this account until the end of
2022. As part of the JRAP Decision received in November 2022, the OEB approved the disposition of Hydro One Networks'
transmission and distribution account balances as at December 31, 2020, including accrued interest, which would be recovered
from ratepayers over a one-year period ending December 31, 2023, and a three-year period ending December 31, 2025,
respectively.
Broadband Deferral
The Company recognizes the incremental costs and incremental revenues attributable to carrying out activities pertaining to
designated broadband projects as defined under Building Broadband Faster Act (Ontario) in this generic deferral account.
Environmental
Hydro One records a liability for the estimated future expenditures required to remediate environmental contamination. A
regulatory asset is recognized to the extent management considers it to be probable that environmental expenditures will be
recovered in the future through the rate-setting process. For the year ended December 31, 2024, the Company has recorded a
portion of the liability as a regulatory asset. In 2024, the revaluation adjustment increased the environmental regulatory asset by
$2 million (2023 - decreased by $9 million) to reflect changes in the recoverable portion of the Company’s PCB and LAR
environmental liabilities. The environmental regulatory asset is amortized to results of operations based on the pattern of actual
expenditures incurred and charged to environmental liabilities. The OEB has the discretion to examine and assess the prudence
and the timing of recovery of all of Hydro One’s actual environmental expenditures.
Stock-based Compensation
The Company recognizes costs associated with share grant plans as a regulatory asset as management considers it probable
that share grant plans' costs will be recovered in the future through the rate-setting process. Share grant costs are transferred to
labour costs at the time they vest and are issued, and are recovered in rates in accordance with recovery of these labour costs.
Getting Ontario Connected Act Variance
On October 31, 2023, the OEB issued its Decision and Order approving the establishment of a generic sector-wide variance
account, effective April 1, 2023. The account was established to record incremental costs of locating underground infrastructure
resulting from the implementation of Provincial legislation: Bill 93, Getting Ontario Connected Act, 2022.
RRRP Variance
Hydro One Remotes receives RRRP amounts from the Independent Electricity System Operator (IESO). As at December 31,
2022, the Company recognized a regulatory asset representing the amounts required to achieve breakeven net income, as
regulated under the cost recovery model, in excess of cumulative RRRP amounts received. In 2024, RRRP amounts received
were higher (2023 - lower) than amounts required to achieve breakeven net income, and as such, the regulatory asset
decreased by $12 million (2023 - increased by $5 million).
Pension Benefit Regulatory Liability
In accordance with OEB rate orders, pension costs are recovered on a cash basis as employer contributions are paid to the
pension fund in accordance with the Pension Benefits Act (Ontario). The Company recognizes the net unfunded or funded status
of pension obligations on the consolidated balance sheets with an offset to the associated regulatory asset or regulatory liability.
The pension benefit obligation is remeasured to the present value of the actuarially determined benefit obligation at each year
end based on an annual actuarial report, with an offset to the associated regulatory asset or regulatory liability, to the extent of
the remeasurement adjustment.

Post-Retirement and Post-Employment Benefits
In accordance with OEB rate orders, post-retirement and post-employment benefits costs are recovered on an accrual basis. The
Company recognizes the net unfunded or funded status of post-retirement and post-employment obligations on the consolidated
balance sheets with an incremental offset to the associated regulatory asset or regulatory liability, as the case may be. A
regulatory asset or regulatory liability is recognized because management considers it to be probable that post-retirement and
post-employment benefit costs will be recovered or returned in the future through the rate-setting process. The post-retirement
and post-employment benefit obligation is remeasured to the present value of the actuarially determined benefit obligation at
each year end based on an annual actuarial report, with an offset to the associated regulatory asset or regulatory liability, as the
case may be, to the extent of the remeasurement adjustment.
RSVA
Hydro One has deferred certain retail settlement variance amounts under the provisions of Article 490 of the OEB’s Accounting
Procedures Handbook. The RSVA account tracks the difference between the cost of power purchased from the IESO and the
cost of power recovered from ratepayers. As part of the JRAP Decision received in November 2022, the OEB approved the
disposition of Hydro One Networks' distribution business' balance as at December 31, 2020, including accrued interest, over a
three-year period ending December 31, 2025.
Earnings Sharing Mechanism Deferral
In March 2019, the OEB approved the establishment of an earnings sharing mechanism deferral account for Hydro One
Networks' distribution segment to record over-earnings including tax impacts, if any, realized for any year from 2018 to 2022.
Under this mechanism, Hydro One shares 50% of regulated earnings that exceed the OEB-approved regulatory return-on-equity
by more than 100 basis points with distribution ratepayers. A similar account was also approved for B2M LP in January 2020,
and Hydro One Networks’ transmission segment and NRLP in April 2020. As part of the JRAP Decision, the account was
approved for the years 2023 to 2027 for both the transmission and distribution businesses. HOSSM's account was approved as
part of the acquisition decision in October 2016 and became effective in 2022. The balance in the account as at December 31,
2024 mostly relates to Hydro One Networks distribution and transmission businesses. As part of the JRAP Decision received in
November 2022, the OEB approved the disposition of Hydro One Networks' distribution business' balance as at December 31,
2020, including accrued interest, over a three-year period ending December 31, 2025.
Distribution Rate Riders
As part of the JRAP Decision, the OEB approved the disposition of certain deferral and variance account balances as at
December 31, 2020, including accrued interest. These approved balances, including those for RSVA, tax rule changes variance,
pension cost differential, and ESM were accumulated in distribution rate riders which makes up the majority of this balance. The
amounts are being disposed of over a three-year period ending December 31, 2025.
Capitalized Overhead Tax Variance
As part of the JRAP Decision, the OEB approved the establishment of a capitalized overhead tax variance account to capture the
difference between the capitalized overheads deducted in calculating the regulatory tax expense included in rates and the actual
capitalized overhead costs deducted in Hydro One's tax returns for Hydro One Networks' transmission and distribution
businesses for the 2016 to 2027 period. Variance amounts are recognized at the earlier of (i) when the tax year has been audited
by the Canada Revenue Agency or (ii) when the taxation year is statute barred.
Tax Rule Changes Variance
The 2019 federal and Ontario budgets (Budgets) provided certain time-limited investment incentives permitting Hydro One to
deduct accelerated capital cost allowance of up to three times the first-year rate for capital investments acquired after November
20, 2018 and placed in-service before January 1, 2028 (Accelerated Depreciation). Following the enactment of the Budget
measures in the second quarter of 2019, the OEB directed all Ontario regulated utilities including Hydro One to track the full
revenue impact of the tax benefits related to the Accelerated Depreciation rules to ratepayers. The tax benefit to be returned to
ratepayers in the future gave rise to a regulatory liability and resulted in a decrease in revenues as current rates do not include
the benefit of the Accelerated Depreciation; therefore, the revenue subject to refund cannot be recognized. As part of the JRAP
Decision received in November 2022, the OEB approved the disposition of Hydro One Networks' transmission and distribution
account balances as at December 31, 2020, including accrued interest, which was to be returned to ratepayers over a one-year
period ending December 31, 2023, and a three-year period ending December 31, 2025, respectively.

OPEB Asymmetrical Carrying Charge Variance Account
On September 14, 2017, the OEB issued its Report of the Board: Regulatory Treatment of Pension and OPEB Costs that
allowed rate-regulated utilities to track the difference between their pension and OPEB costs calculated under the accrual
method and the cash payment method, effective January 1, 2018, and record the carrying charges associated with the balance
on an asymmetrical basis. As part of the JRAP Decision received in November 2022, the OEB approved the disposition of Hydro
One Networks’ transmission and distribution account balances as at December 31, 2020, including accrued interest, which was
to be returned to ratepayers over a one-year period ending December 31, 2023, and a three-year period ending December 31,
2025, respectively.
External Revenue Variance
The external revenue variance account balance reflects the difference between Hydro One Networks' transmission business'
actual export service revenue and external revenues from secondary land use, and the OEB-approved amounts. The account
also records the difference between actual net external station maintenance, engineering and construction services revenue, and
other external revenue, and the OEB-approved amounts. As part of the JRAP Decision received in November 2022, the OEB
approved the disposition of the account balance as at December 31, 2020, including accrued interest, over a one-year period
ending December 31, 2023.
Asset Removal Costs Cumulative Variance
In April 2020, the OEB approved the establishment of an asset removal costs cumulative variance account for Hydro One
Networks' transmission business to record the difference between the revenue requirement associated with forecast asset
removal costs included in depreciation expense and actual asset removal costs incurred from 2020 to 2022. This account is
asymmetrical to the benefit of ratepayers on a cumulative basis over the 2020 to 2022 rate period. As part of the JRAP Decision
received in November 2022, the OEB approved the disposition of the account balance as at December 31, 2020, including
accrued interest, over a one-year period ending December 31, 2023. As part of the same decision, the OEB approved the
continuance of this account for Hydro One Networks’ transmission business and the establishment of this account for Hydro One
Networks’ distribution business for the 2023 to 2027 period.
Pension Cost Differential
Variances between the OM&A pension cost recognized and the cost embedded in rates as part of the rate-setting process for
Hydro One Networks' transmission and distribution businesses are recognized as a regulatory asset or regulatory liability, as the
case may be. As part of the JRAP Decision received in November 2022, the OEB approved the disposition of Hydro One
Networks' transmission and distribution account balances as at December 31, 2020, including accrued interest, which will be
returned to ratepayers over a one-year period ending December 31, 2023 and a three-year period ending December 31, 2025,
respectively.

17. FAIR VALUE OF FINANCIAL INSTRUMENTS AND RISK MANAGEMENT
Fair value is considered to be the exchange price in an orderly transaction between market participants to sell an asset or
transfer a liability at the measurement date. The fair value definition focuses on an exit price, which is the price that would be
received in the sale of an asset or the amount that would be paid to transfer a liability.
Hydro One classifies its fair value measurements based on the following hierarchy, as prescribed by the accounting guidance for
fair value, which prioritizes the inputs to valuation techniques used to measure fair value into three levels:
Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities that Hydro One has the ability to
access. An active market for the asset or liability is one in which transactions for the asset or liability occur with sufficient
frequency and volume to provide ongoing pricing information.
Level 2 inputs are those other than quoted market prices that are observable, either directly or indirectly, for an asset or liability.
Level 2 inputs include, but are not limited to, quoted prices for similar assets or liabilities in an active market, quoted prices for
identical or similar assets or liabilities in markets that are not active and inputs other than quoted market prices that are
observable for the asset or liability, such as interest-rate curves and yield curves observable at commonly quoted intervals,
volatilities, credit risk and default rates. A Level 2 measurement cannot have more than an insignificant portion of the valuation
based on unobservable inputs.
Level 3 inputs are any fair value measurements that include unobservable inputs for the asset or liability for more than an
insignificant portion of the valuation. A Level 3 measurement may be based primarily on Level 2 inputs.
Non-Derivative Financial Assets and Liabilities
As at December 31, 2024 and 2023, the Company’s carrying amounts of cash and cash equivalents, accounts receivable, due
from related parties, short-term notes payable, accounts payable, and due to related parties are representative of fair value due
to the short-term nature of these instruments.
Fair Value Measurements of Long-Term Debt
The carrying values and fair values of the Company’s long-term debt as at December 31, 2024 and 2023 are as follows:

designated as a cash flow hedge. This cash flow hedge is intended to offset the variability of interest rates between December
21, 2023 and September 21, 2026.
As at December 31, 2024 and 2023, the Company had no derivative instruments classified as undesignated contracts.

Hydro One Limited | 2024 Annual Report
The fair value of the interest rate swaps designated as cash flow hedges is determined using a discounted cash flow method
based on period-end swap yield curves.
The fair value of the long-term debt is based on unadjusted period-end market prices for the same or similar debt of the same
remaining maturities.
There were no transfers between any of the fair value levels during the years ended December 31, 2024 or 2023.
Risk Management
Exposure to market risk, credit risk and liquidity risk arises in the normal course of the Company’s business.
Market Risk
Market risk refers primarily to the risk of loss which results from changes in values, foreign exchange rates and interest rates.
The Company is exposed to fluctuations in interest rates, as its regulated return on equity is derived using a formulaic approach
that takes anticipated interest rates into account. The Company is not currently exposed to material commodity price risk or
material foreign exchange risk.
The Company uses a combination of fixed and variable-rate debt to manage the mix of its debt portfolio. The Company also uses
derivative financial instruments to manage interest-rate risk. The Company may utilize interest-rate swaps designated as fair
value hedges as a means to manage its interest rate exposure to achieve a lower cost of debt. The Company may also utilize
interest-rate derivative instruments, such as cash flow hedges, to manage its exposure to short-term interest rates or to lock in
interest-rate levels on forecasted financing.
A hypothetical 100 basis point increase in interest rates associated with variable-rate debt would not have resulted in a significant
decrease to Hydro One’s net income for the years ended December 31, 2024 and 2023, respectively.
For derivative instruments that are designated and qualify as cash flow hedges, the unrealized gain or loss, after tax, on the
derivative instrument is recorded as OCI or OCL and is reclassified to net income or net loss in the same period during which the
hedged transaction affects results of operations. The following table shows the amounts recorded in OCL and reclassified to
financing charges for the years ended December 31, 2024 and 2023:

This resulted in an AOCL of $5 million related to cash flow hedges as at December 31, 2024 (2023 - $1 million).
The Company estimates that the amount of AOCL, after tax, related to cash flow hedges to be reclassified to results of
operations in the next 12 months is approximately $3 million. Actual amounts reclassified to results of operations depend on the
interest rate in effect until the derivative contracts mature. For all forecasted transactions, as at December 31, 2024, the
maximum term over which the Company is hedging exposures to the variability of cash flows is approximately two years.
The Pension Plan manages market risk by diversifying investments in accordance with the Pension Plan’s Statement of
Investment Policies and Procedures. Interest rate risk arises from the possibility that changes in interest rates will affect the fair
value of the Pension Plan’s financial instruments. In addition, changes in interest rates can also impact discount rates which
impact the valuation of the pension and post-retirement and post-employment liabilities. Currency risk is the risk that the value of
the Pension Plan’s financial instruments will fluctuate due to changes in foreign currencies relative to the Canadian dollar. Other
price risk is the risk that the value of the Pension Plan’s investments in equity securities will fluctuate as a result of changes in
market prices, other than those arising from interest risk or currency risk. All three factors may contribute to changes in values of
the Pension Plan investments. See Note 19 - Pension and Post-Retirement and Post-Employment Benefits for further details.
Credit Risk
Financial assets create a risk that a counterparty will fail to discharge an obligation, causing a financial loss. As at December 31,
2024 and 2023, there were no significant concentrations of credit risk with respect to any class of financial assets. The
Company’s revenue is earned from a broad base of customers. As a result, Hydro One did not earn a material amount of
revenue from any single customer. As at December 31, 2024 and 2023, there was no material accounts receivable balance due
from any single customer.
As at December 31, 2024, the Company’s allowance for doubtful accounts was $61 million (2023 - $57 million). The allowance
for doubtful accounts reflects the Company's CECL for all accounts receivable balances, which are based on historical overdue
balances, customer payments and write-offs. As at December 31, 2024, approximately 7% (2023 - 5%) of the Company’s net
accounts receivable were outstanding for more than 60 days.

Hydro One manages its counterparty credit risk through various techniques including (i) entering into transactions with highly
rated counterparties, (ii) limiting total exposure levels with individual counterparties, (iii) entering into master agreements which
enable net settlement and the contractual right of offset, and (iv) monitoring the financial condition of counterparties. The
Company monitors current credit exposure to counterparties on both an individual and an aggregate basis. The Company’s credit
risk for accounts receivable is limited to the carrying amounts on the consolidated balance sheets.
Derivative financial instruments result in exposure to credit risk since there is a risk of counterparty default. The maximum credit
exposure of derivative contracts, before collateral, is represented by the fair value of contracts in an asset position at the
reporting date. As at December 31, 2024 and 2023, Hydro One’s credit exposure for all derivative instruments and applicable
payables was with one financial institution with investment grade credit ratings as counterparty.
The Pension Plan manages its counterparty credit risk with respect to bonds by investing in investment-grade corporate and
government bonds and with respect to derivative instruments by transacting only with highly rated financial institutions and by
ensuring that exposure is diversified across counterparties.
Liquidity Risk
Liquidity risk refers to the Company’s ability to meet its financial obligations as they come due. Hydro One meets its short-term
operating liquidity requirements using cash and cash equivalents on hand, funds from operations, the issuance of commercial
paper, and the Operating Credit Facilities. The short-term liquidity under the commercial paper program, the Operating Credit
Facilities, and anticipated levels of funds from operations are expected to be sufficient to fund the Company’s operating
requirements.
In February 2024, Hydro One Inc. filed a short form base shelf prospectus in connection with its MTN Program, which expires in
March 2026. Hydro One’s Universal Base Shelf Prospectus allows it to offer, from time to time in one or more public offerings,
debt, equity or other securities, or any combination thereof, during the 25-month period ending on September 19, 2026.
On November 29, 2024, HOHL filed a short form base shelf prospectus (U.S. Debt Shelf Prospectus) with securities regulatory
authorities in Canada and the U.S. to replace a previous prospectus that would otherwise have expired in December 2024. The
U.S. Debt Shelf Prospectus, expiring in December 2026, allows HOHL to offer, from time to time in one or more public offerings,
debt securities, unconditionally guaranteed by Hydro One. As at December 31, 2024, no securities have been issued under the
U.S. Debt Shelf Prospectus.
The Pension Plan’s short-term liquidity is provided through cash and cash equivalents, contributions, investment income and
proceeds from investment transactions. In the event that investments must be sold quickly to meet current obligations, the
majority of the Pension Plan’s assets are invested in securities that are traded in an active market and can be readily disposed of
as liquidity needs arise.
18. CAPITAL MANAGEMENT
The Company’s objectives with respect to its capital structure are to maintain effective access to capital on a long-term basis at
reasonable rates, and to deliver appropriate financial returns. In order to ensure ongoing access to capital, the Company targets
to maintain strong credit quality. As at December 31, 2024 and 2023, the Company’s capital structure was as follows:
As at December 31 (millions of dollars)

Hydro One Inc. has customary covenants typically associated with long-term debt. Long-term debt and credit facility covenants
limit permissible debt to 75% of its total capitalization, limit the ability to sell assets, and impose a negative pledge provision,
subject to customary exceptions. As at December 31, 2024, the Company was in compliance with all financial covenants and
limitations associated with the outstanding borrowings and credit facilities.

19. PENSION AND POST-RETIREMENT AND POST-EMPLOYMENT BENEFITS
Hydro One has a Pension Plan, a supplementary pension plan (Supplementary Plan), post-retirement and post-employment
benefit plans (Benefit Plans), and a DC Plan.
Pension Plan, Supplementary Plan, and Benefit Plans
The Pension Plan is a defined benefit contributory plan which covers eligible regular employees of Hydro One and its
subsidiaries. The Pension Plan provides benefits based on the highest three-year average pensionable earnings up to March 31,
2025. Beginning April 1, 2025, all service for all groups on a go-forward basis will be calculated using the highest five-year
average pensionable earnings. For management employees who commenced employment on or after January 1, 2004, and for
Society-represented staff hired after November 17, 2005, benefits are based on the highest five-year average pensionable
earnings for all their service. After retirement, pensions are indexed to inflation. Membership in the Pension Plan was closed to
management employees who were not eligible to join the Pension Plan as of September 30, 2015. These employees are eligible
to join the DC Plan.
Company and employee contributions to the Pension Plan are based on actuarial reports, including valuations performed at least
every three years, and actual or projected levels of pensionable earnings, as applicable. The most recent actuarial valuation was
performed effective December 31, 2023, and filed on September 23, 2024. Total annual cash Pension Plan employer
contributions for 2024 were $75 million (2023 - $69 million). Estimated annual Pension Plan employer contributions for the years
2025, 2026, 2027, 2028, 2029 and 2030 are approximately $78 million, $80 million, $83 million, $86 million, $89 million, and $92
million respectively.
The Supplementary Plan provides members of the Pension Plan with benefits that would have been earned and payable under
the Pension Plan beyond the limitations imposed by the Income Tax Act (Canada). The Supplementary Plan obligation is
included with other post-retirement and post-employment benefit obligations on the consolidated balance sheets.
Hydro One recognizes the funded or underfunded status of the Pension Plan and Benefit Plans as an asset or liability on its
consolidated balance sheets, with offsetting regulatory assets and regulatory liabilities as appropriate. The funded benefit asset
and underfunded benefit obligations for the Pension Plan and Benefit Plans, in the absence of regulatory accounting, would be
recognized in AOCI. The impact of changes in assumptions used to measure pension and post-retirement benefit obligations is
generally recognized over the expected average remaining service period of the employees and uses the corridor approach for
the post-retirement benefit plan. For the post-employment benefit plan, the impact of changes in assumptions are recognized
immediately in the net periodic benefit cost. The measurement date for the Plans is December 31.

Transfers from Other Plans
Hydro One and Inergi LP agreed to transfer the employment of certain Inergi LP employees (Transferred Employees) to Hydro
One Networks. Employees related to the Information Technology Operations, Finance and Accounting, Payroll, Source to Pay,
Settlements and certain Shared Services functions were transferred over a one-year period ending January 1, 2022. The
Transferred Employees who were participants in the Inergi LP Pension Plan (Inergi Plan) became participants in the Hydro One
Pension Plan upon transfer to Hydro One Networks. On March 2, 2023, the assets and liabilities of the Inergi Plan were
transferred to the Pension Plan. The value of assets and liabilities of the Inergi Plan transferred to the Pension Plan were
approximately $377 million and $333 million, respectively, as at the date of transfer. Inergi and Hydro One Networks also agreed
to transfer OPEB liabilities related to the Transferred Employees to Hydro One’s Benefit Plans.
Eligible Inergi retirees were transferred to the Benefit Plans on June 1, 2023. The transfer of the OPEB liability of $15 million
related to these retirees was completed in the second quarter of 2023. The liability was recorded as a post-retirement and post-
employment benefit liability with an offset to OCL, and cash totalling $3 million was transferred to Hydro One, in accordance with
the agreement. Both the OCI resulting from the transfer of the cash asset and the OCL resulting from the transfer of OPEB
liabilities are being recognized in net income over the expected average remaining life expectancy of the retirees and other
former members employees.

The funded or unfunded status of the Pension Plan and Benefits Plans refers to the difference between the fair value of plan
assets and the PBO for the Pension Plan and Benefit Plans. The funded/unfunded status changes over time due to several
factors, including contribution levels, assumed discount rates and actual returns on plan assets.

2024, post-retirement and post-employment costs of $113 million (2023 - $111 million) were attributed to labour, of which $74 million (2023 - $77 million) was
charged to operations, and $39 million (2023 - $36 million) was capitalized as part of the cost of property, plant and equipment and intangible assets.
Assumptions
The measurement of the obligations of the Pension Plan and Benefit Plans and the costs of providing benefits under the Pension
Plan and Benefit Plans involves various factors, including the development of valuation assumptions and accounting policy
elections. When developing the required assumptions, the Company considers historical information as well as future
expectations. The measurement of benefit obligations and costs is impacted by several assumptions including the discount rate
applied to benefit obligations, the long-term expected rate of return on plan assets, Hydro One’s expected level of contributions
to the Pension Plan and Benefit Plans, the incidence of mortality, the expected remaining service period of plan participants, the
level of compensation and rate of compensation increases, employee age, length of service, and the anticipated rate of increase
of health care costs, among other factors. The impact of changes in assumptions used to measure the obligations of the Pension
Plan and Benefit Plans is generally recognized over the expected average remaining service period of the plan participants. In
selecting the expected rate of return on plan assets, Hydro One considers historical economic indicators that impact asset
returns, as well as expectations regarding future long-term capital market performance, weighted by target asset class
allocations. In general, equity securities, real estate and private equity investments are forecasted to have higher returns than
fixed-income securities.

2031).
The discount rate used to determine the current year pension obligation and the subsequent year’s net periodic benefit costs is
based on a yield curve approach. Under the yield curve approach, expected future benefit payments for each plan are
discounted by a rate on a third-party bond yield curve corresponding to each duration. The yield curve is based on “AA” long-
term corporate bonds. A single discount rate is calculated that would yield the same present value as the sum of the discounted
cash flows.

Pension Plan Assets
Investment Strategy
On a regular basis, Hydro One evaluates its investment strategy to ensure that Pension Plan assets will be sufficient to pay
Pension Plan benefits when it comes due. As part of this ongoing evaluation, Hydro One may make changes to its targeted asset
allocation and investment strategy. The Pension Plan is managed at a net asset level. The main objective of the Pension Plan is
to sustain a certain level of net assets in order to meet the pension obligations of the Company. The Pension Plan fulfils its
primary objective by adhering to specific investment policies outlined in its Statement of Investment Policies and Procedures
(SIPP), which is reviewed and approved annually by the Human Resource Committee of Hydro One’s Board of Directors. The
Company manages net assets by engaging external investment managers who are charged with the fiduciary responsibility of
investing existing funds and new funds (current year’s employee and employer contributions) in accordance with the approved
SIPP. The performance of the underlying investment managers is monitored through a governance structure. Increases in net
assets are a direct result of investment income generated by investments held by the Pension Plan and contributions to the
Pension Plan by eligible employees and by the Company. The main use of net assets is for benefit payments to eligible Pension
Plan members.
Pension Plan Asset Mix
As at December 31, 2024, the Pension Plan actual weighted average, target, and range asset allocations were as follows:
Actual (%)
Target Allocation (%)

million (2023 - $539 million) of debt securities of the Province.
Concentrations of Credit Risk
Hydro One evaluated its Pension Plan’s asset portfolio for the existence of significant concentrations of credit risk as at
December 31, 2024 and 2023. Concentrations that were evaluated include, but are not limited to, investment concentrations in a
single entity, concentrations in a type of industry, and concentrations in individual funds. As at December 31, 2024 and 2023,
there were no significant concentrations (defined as greater than 10% of plan assets) of risk in the Pension Plan’s assets.

The Pension Plan's Statement of Investment Beliefs and Guidelines provides guidelines and restrictions for eligible investments
taking into account credit ratings, maximum investment exposure and other controls in order to limit the impact of this risk. The
Pension Plan manages its counterparty credit risk with respect to bonds by investing in investment-grade and government bonds
and with respect to derivative instruments by transacting only with highly rated financial institutions, and also by ensuring that
exposure is diversified across counterparties. The risk of default on transactions in listed securities is considered minimal, as the
trade will fail if either party to the transaction does not meet its obligation.

Changes in the Fair Value of Financial Instruments Classified in Level 3
The following table summarizes the changes in fair value of financial instruments classified in Level 3 for the years ended
December 31, 2024 and 2023. The Pension Plan classifies financial instruments as Level 3 when the fair value is measured
based on at least one significant input that is not observable in the markets or due to lack of liquidity in certain markets. The
gains and losses presented in the table below could, therefore, include changes in fair value based on both observable and
unobservable inputs. The Level 3 financial instruments are comprised of pooled funds whose valuations are provided by the
investment managers. Sensitivity analysis is not provided as the underlying assumptions used by the investment managers are

There were no transfers between any of the fair value levels during the years ended December 31, 2024 and 2023.
Valuation Techniques Used to Determine Fair Value
Pooled funds mainly consist of private equity, real estate infrastructure and private debt investments. Private equity investments
represent private equity funds that invest in operating companies that are not publicly traded on a stock exchange. Investment
strategies in private equity include limited partnerships in businesses that are characterized by high internal growth and
operational efficiencies, venture capital, leveraged buyouts and special situations such as distressed investments. Real estate
and infrastructure investments represent funds that invest in real assets which are not publicly traded on a stock exchange.
Investment strategies in real estate include limited partnerships that seek to generate a total return through income and capital
growth by investing primarily in global and Canadian limited partnerships. Investment strategies in infrastructure include limited
partnerships in core infrastructure assets focusing on assets that are expected to generate stable, long-term cash flows and
deliver incremental returns relative to conventional fixed-income investments. Private equity, real estate and infrastructure
valuations are reported by the fund manager and are based on the valuation of the underlying investments which includes inputs
such as cost, operating results, discounted future cash flows and market-based comparable data. Private debt valuations are
reported by the fund manager. Private debt is credit that is extended to companies on a bilaterally negotiated basis. It is not
readily marketable and takes a wide range of forms, such as senior secured and unsecured loans, infrastructure project
financing, investments secured by real estate assets, and securitized lease/loan obligations supported by a pool of assets. Since
these valuation inputs are not highly observable, private equity, real estate infrastructure and private debt investments have been
categorized as Level 3 within pooled funds.
Cash equivalents consist of demand cash deposits held with banks and cash held by the investment managers. Cash
equivalents are categorized as Level 1.
Short-term securities are valued at cost plus accrued interest, which approximates fair value due to their short-term nature.
Short-term securities are categorized as Level 2.
Derivative instruments are used to hedge the Pension Plan’s foreign currency exposure back to Canadian dollars. The notional
principal amount of contracts outstanding as at December 31, 2024 was $391 million (2023 - $375 million). The most significant
currencies being hedged against the Canadian dollar are the United States dollar, euro, and British pound sterling. The net
realized loss on contracts for the year ended December 31, 2024 was $3 million (2023 - $nil net realized loss). The terms to
maturity of the forward exchange contracts as at December 31, 2024 are within three months. The fair value is determined using
standard interpolation methodology primarily based on the World Markets exchange rates. Derivative instruments are
categorized as Level 2.
Corporate shares are valued based on quoted prices in active markets and are categorized as Level 1. Corporate shares which
are valued based on quoted prices in active markets, but held within a pension investment holding company, are categorized as
Level 2. Investments denominated in foreign currencies are translated into Canadian currency at year-end rates of exchange.
Bonds and debentures are presented at published closing trade quotations and are categorized as Level 2.
DC Plan
Hydro One established a DC Plan effective January 1, 2016. The DC Plan covers eligible management employees hired on or
after January 1, 2016, as well as management employees hired before January 1, 2016 who were not eligible to join the Pension
Plan as of September 30, 2015. Members of the DC Plan have an option to contribute 4%, 5% or 6% of their pensionable
earnings, with matching contributions by Hydro One up to an annual contribution limit. There is also a Supplementary Notional
Plan that provides members of the DC Plan with employer contributions beyond the limitations imposed by the Income Tax Act
(Canada) in the form of credits to a notional account. Hydro One contributions to the DC Plan for the year ended December 31,
2024 were $5 million (2023 - $4 million).

Hydro One records a liability for the estimated future expenditures for LAR and for the phase-out and destruction of PCB-
contaminated mineral oil removed from electrical equipment when it is determined that future environmental remediation
expenditures are probable under existing statute or regulation and the amount of the future expenditures can be reasonably
estimated.
There are uncertainties in estimating future environmental costs due to potential external events such as changes in legislation
or regulations, and advances in remediation technologies. In determining the amounts to be recorded as environmental liabilities,
the Company estimates the current cost of completing required work and makes assumptions as to when the future expenditures
will actually be incurred in order to generate future cash flow information. A long-term inflation rate assumption of approximately
2% has been used to express these current cost estimates as estimated future expenditures. Future expenditures have been
discounted using factors ranging from approximately 2.0% to 6.3% (2023 - 2.0% to 6.3%) depending on the appropriate rate for
the period when expenditures are expected to be incurred. All factors used in estimating the Company’s environmental liabilities
represent management’s best estimates of the present value of costs required to meet existing legislation or regulations.
However, it is reasonably possible that numbers or volumes of contaminated assets, cost estimates to perform work, inflation
assumptions and the assumed pattern of annual cash flows may differ significantly from the Company’s current assumptions. In
addition, with respect to the PCB environmental liability, the availability of critical resources such as skilled labour and
replacement assets and the ability to take maintenance outages in critical facilities may influence the timing of expenditures.
PCBs
Environment Canada regulations, enacted under the Canadian Environmental Protection Act, 1999, govern the management,
storage and disposal of PCBs based on certain criteria, including type of equipment, in-use status, and PCB-contamination
thresholds. Under current regulations, Hydro One’s PCBs have to be disposed of by the end of 2025, with the exception of
specifically exempted equipment. Contaminated equipment will generally be replaced, or will be decontaminated by removing
PCB-contaminated insulating oil and retro filling with replacement oil that contains PCBs in concentrations of less than 2 ppm.
As at December 31, 2024, the Company’s best estimate of the total estimated future expenditures to comply with current PCB
regulations was $6 million (2023 - $39 million). These expenditures are expected to be incurred in 2025. As a result of its annual
review of environmental liabilities, the Company recorded a revaluation adjustment in 2024 to increase the PCB environmental
liability by $1 million (2023 - $17 million).

LAR
As at December 31, 2024, the Company’s best estimate of the total estimated future expenditures to complete its LAR program
was $41 million (2023 - $41 million). These expenditures are expected to be incurred over the period from 2025 to 2045. As a
result of its annual review of environmental liabilities, the Company recorded a revaluation adjustment in 2024 to increase the
LAR environmental liability by $4 million (2023 - decrease of $1 million).
21. ASSET RETIREMENT OBLIGATIONS
Hydro One records a liability for the estimated future expenditures for the removal and disposal of asbestos-containing materials
installed in some of its facilities, as well as for the estimated expenditure for the future decommissioning and removal of some
diesel generating stations and related assets operated by its subsidiary, Hydro One Remotes.
Asset retirement obligations, which represent legal obligations associated with the retirement of certain tangible long-lived
assets, are computed as the present value of the projected expenditures for the future retirement of specific assets and are
recognized in the period in which the liability is incurred, if a reasonable estimate can be made. If the asset remains in service at
the recognition date, the present value of the liability is added to the carrying amount of the associated asset in the period the
liability is incurred and this additional carrying amount is depreciated over the remaining life of the asset. If an asset retirement
obligation is recorded in respect of an out-of-service asset, the asset retirement cost is charged to results of operations.
Subsequent to the initial recognition, the liability is adjusted for any revisions to the estimated future cash flows associated with
the asset retirement obligation, which can occur due to a number of factors including, but not limited to, cost escalation, changes
in technology applicable to the assets to be retired, changes in legislation or regulations, as well as for accretion of the liability
due to the passage of time until the obligation is settled. Depreciation expense is adjusted prospectively for any increases or
decreases to the carrying amount of the associated asset.
Some of the Company’s transmission and distribution assets, particularly those located on unowned easements and rights-of-
way, may have asset retirement obligations, conditional or otherwise. The majority of the Company’s easements and rights-of-
way are either of perpetual duration or are automatically renewed annually. Land rights with finite terms are generally subject to
extension or renewal. As the Company expects to use the majority of its facilities in perpetuity, no asset retirement obligations
have been recorded for these assets. If, at some future date, a particular facility is shown not to meet the perpetuity assumption,
it will be reviewed to determine whether an estimable asset retirement obligation exists. In such a case, an asset retirement
obligation would be recorded at that time.
In determining the amounts to be recorded as asset retirement obligations, the Company estimates the current fair value for
completing required work and makes assumptions as to when the future expenditures will actually be incurred, in order to
generate future cash flow information. A long-term inflation assumption of approximately 2% has been used to express these
current cost estimates as estimated future expenditures. Future expenditures have been discounted using factors ranging from
approximately 1.0% to 3.0% (2023 - 2.0% to 4.0%) depending on the appropriate rate for the period when expenditures are
expected to be incurred. All factors used in estimating the Company’s asset retirement obligations represent management’s best
estimates of the cost required to meet existing legislation or regulations. However, it is reasonably possible that numbers or
volumes of contaminated assets, cost estimates to perform work, inflation assumptions and the assumed pattern of annual cash
flows may differ significantly from the Company’s current assumptions. Asset retirement obligations are reviewed annually or
more frequently if significant changes in regulations or other relevant factors occur. Estimate changes are accounted for
prospectively. As a result of its annual review of asset retirement obligations, the Company recorded a revaluation adjustment in
2024 to increase the asset retirement obligations related to the decommissioning and removal of diesel generating station within
the Hydro One Remotes operating territory by $2 million (2023 - $6 million) while there was no change to the asset retirement
obligations related the removal and disposal of asbestos-containing materials installed in some of its facilities (2023 - increase of
$1 million).
As at December 31, 2024, Hydro One had recorded total asset retirement obligations of $38 million (2023 - $36 million), primarily
consisting of the estimated future expenditures associated with the decommissioning and removal of diesel generating stations
of $19 million (2023 - $17 million), and the removal and disposal of asbestos-containing materials installed in some of its facilities
of $18 million (2023 - $18 million).

Preferred Shares
The Company is authorized to issue an unlimited number of preferred shares, issuable in series. As at December 31, 2024 and
2023, two series of preferred shares were authorized for issuance: the Series 1 preferred shares and the Series 2 preferred
shares. As at December 31, 2024, and 2023, the Company had no Preferred Shares and no Series 2 preferred shares issued
and outstanding.
Hydro One may from time to time issue preferred shares in one or more series. Prior to issuing shares in a series, the Hydro One
Board of Directors is required to fix the number of shares in the series and determine the designation, rights, privileges,
restrictions and conditions attaching to that series of preferred shares. Holders of Hydro One’s preferred shares are not entitled
to receive notice of, to attend or to vote at any meeting of the shareholders of Hydro One except that votes may be granted to a
series of preferred shares when dividends have not been paid on any one or more series as determined by the applicable series
provisions. Each series of preferred shares ranks on parity with every other series of preferred shares, and are entitled to a
preference over the common shares and any other shares ranking junior to the preferred shares, with respect to dividends and
the distribution of assets and return of capital in the event of the liquidation, dissolution or winding up of Hydro One.
Share Ownership Restrictions
The Electricity Act imposes share ownership restrictions on securities of Hydro One carrying a voting right (Voting Securities).
These restrictions provide that no person or company (or combination of persons or companies acting jointly or in concert) may
beneficially own or exercise control or direction over more than 10% of any class or series of Voting Securities, including
common shares of the Company (Share Ownership Restrictions). The Share Ownership Restrictions do not apply to Voting
Securities held by the Province, nor to an underwriter who holds Voting Securities solely for the purpose of distributing those
securities to purchasers who comply with the Share Ownership Restrictions.
24. DIVIDENDS

Share Grant Plans
Hydro One has two share grant plans (Share Grant Plans), one for the benefit of certain members of the PWU (PWU Share
Grant Plan) and one for the benefit of certain members of the Society (Society Share Grant Plan).
The PWU Share Grant Plan provides for the issuance of common shares of Hydro One from treasury to certain eligible members
of the PWU annually, commencing on April 1, 2017 and continuing until the earlier of April 1, 2028 or the date an eligible
employee no longer meets the eligibility criteria of the PWU Share Grant Plan. To be eligible, an employee must be a member of
the Pension Plan on April 1, 2015, be employed on the date that the annual share issuance occurs and continue to have under
35 years of service. The requisite service period for the PWU Share Grant Plan began on July 3, 2015, which is the date that the
share grant plan was ratified by the PWU. The number of common shares issued annually to each eligible employee will be
equal to 2.7% of such eligible employee’s salary as of April 1, 2015, divided by $20.50, being the price of the common shares of
Hydro One in its Initial Public Offering (IPO). The aggregate number of common shares issuable under the PWU Share Grant
Plan shall not exceed 3,981,763 common shares. In 2015, 3,979,062 common shares were granted under the PWU Share Grant
Plan.
The Society Share Grant Plan provides for the issuance of common shares of Hydro One from treasury to certain eligible
members of the Society annually, commencing on April 1, 2018 and continuing until the earlier of April 1, 2029 or the date an
eligible employee no longer meets the eligibility criteria of the Society Share Grant Plan. To be eligible, an employee must be a
member of the Pension Plan on September 1, 2015, be employed on the date that the annual share issuance occurs and
continue to have under 35 years of service. Therefore, the requisite service period for the Society Share Grant Plan began on
September 1, 2015. The number of common shares issued annually to each eligible employee will be equal to 2.0% of such
eligible employee’s salary as of September 1, 2015, divided by $20.50, being the price of the common shares of Hydro One in its
IPO. The aggregate number of common shares issuable under the Society Share Grant Plan shall not exceed 1,434,686
common shares. In 2015, 1,433,292 common shares were granted under the Society Share Grant Plan.
The fair value of the Hydro One 2015 share grants of $111 million was estimated based on the grant date share price of $20.50
and is recognized using the graded-vesting attribution method as the share grant plans have both a performance condition and a
service condition. In 2024, 348,678 common shares (2023 - 362,289) were issued under the Share Grant Plans. Total share-
based compensation recognized during 2024 was $2 million (2023 - $3 million) and was recorded as a regulatory asset.

Directors' DSU Plan
Under the Directors’ DSU Plan, directors can elect to receive credit for their annual cash retainer in a notional account of DSUs in
lieu of cash. Hydro One’s Board of Directors may also determine from time to time that special circumstances exist that would
reasonably justify the grant of DSUs to a director as compensation in addition to any regular retainer or fee to which the director
is entitled. Each DSU represents a unit with an underlying value equivalent to the value of one common share of the Company
and is entitled to accrue common share dividend equivalents in the form of additional DSUs at the time dividends are paid,
subsequent to declaration by Hydro One’s Board of Directors.
A summary of DSU awards activity under the Directors' DSU Plan during the years ended December 31, 2024 and 2023 is

recorded at the closing price of the Company's common shares of $44.27. This liability is included in other long-term liabilities on
the consolidated balance sheets.
Management DSU Plan
Under the Management DSU Plan, eligible executive employees can elect to receive a specified proportion of their annual short-
term incentive in a notional account of DSUs in lieu of cash. Each DSU represents a unit with an underlying value equivalent to
the value of one common share of the Company and is entitled to accrue common share dividend equivalents in the form of
additional DSUs at the time dividends are paid, subsequent to declaration by Hydro One’s Board of Directors.

has been recorded at the closing price of the Company's common shares of $44.27. This liability is included in other long-term
liabilities on the consolidated balance sheets.
Employee Share Ownership Plan
In 2015, Hydro One established Employee Share Ownership Plans (ESOP) for certain eligible management and non-
represented employees (Management ESOP) and for certain eligible Society-represented staff (Society ESOP). Under the
Management ESOP, the eligible management and non-represented employees may contribute between 1% and 6% of their base
salary towards purchasing common shares of Hydro One. The Company matches 50% of their contributions, up to a maximum
Company contribution of $25,000 per calendar year. Under the Society ESOP, the eligible Society-represented staff may
contribute between 1% and 4% of their base salary towards purchasing common shares of Hydro One. The Company matches
25% of their contributions, with no maximum Company contribution per calendar year.

Hydro One. The Company matches 33% of their contribution, with no maximum Company contribution per calendar year. In
2024, Company contributions made under the ESOP were $5 million (2023 - $3 million).
LTIP
Effective August 31, 2015, the Board of Directors of Hydro One adopted an LTIP. Under the LTIP, long-term incentives were
granted to certain executive and management employees of Hydro One and its subsidiaries, and all equity-based awards would
either be settled in newly issued shares of Hydro One from treasury or cash, subject to Hydro One’s discretion, consistent with
the provisions of the plan which also permit the participants to surrender a portion of their awards to satisfy related withholding
taxes requirements. The aggregate number of shares issuable under the LTIP shall not exceed 11,900,000 shares of Hydro One.
The LTIP provides flexibility to award a range of vehicles, including Performance Share Units (PSUs), RSUs, stock options, share
appreciation rights, restricted shares, DSUs, and other share-based awards. The mix of vehicles is intended to vary by role to
recognize the level of executive accountability for overall business performance.
PSUs and RSUs

December 31, 2024 was $10 million (2023 - $3 million).
Society RSU Plan
As a result of the renewal of the Company's prior collective agreement with members of the Society, the Company provided
equity compensation in the form of RSUs to certain eligible members. The equity compensation provides for the purchase of
common shares of Hydro One from the open market, effective March 1, 2021 in one equity grant vesting in equal portions over a
two-year period. To be eligible, an employee must be an employee of the Company as of July 30, 2021, the date the plan was
ratified by the Society; the grant date. The number of common shares issued to each eligible employee will be equal to 1.0% of
such eligible employee’s salary as of April 1, 2021, divided by $30.80, being the price of the common shares of Hydro One at the
grant date. Each RSU is entitled to accrue common share dividend equivalents in the form of additional RSUs at the time
dividends are paid, subsequent to declaration by Hydro One’s Board of Directors.

B2M LP
On December 16, 2014, transmission assets totalling $526 million were transferred from Hydro One Networks to B2M LP. This
was financed by 60% debt ($316 million) and 40% equity ($210 million). On December 17, 2014, the Saugeen Ojibway Nation
(SON) acquired a 34.2% equity interest in B2M LP for consideration of $72 million, representing the fair value of the equity
interest acquired. The SON’s investment in B2M LP consists of $50 million of Class A units and $22 million of Class B units.
The Class B units have a mandatory put option which requires that upon the occurrence of an enforcement event (i.e., an event
of default such as a debt default by the SON or insolvency event), Hydro One purchases the Class B units of B2M LP for net
book value on the redemption date. The noncontrolling interest relating to the Class B units is classified on the consolidated
balance sheet as temporary equity because the redemption feature is outside the control of the Company. The balance of the
noncontrolling interest is classified within equity.

NRLP
On September 18, 2019, Hydro One Networks sold to the Six Nations of the Grand River Development Corporation and, through
a trust, to the Mississaugas of the Credit First Nation a 25.0% and 0.1% equity interest in NRLP partnership units, respectively,
for total consideration of $12 million, representing the fair value of the equity interest acquired. On January 31, 2020, the
Mississaugas of the Credit First Nation purchased an additional 19.9% equity interest in NRLP partnership units from Hydro One
Networks for total cash consideration of $9 million. Following this transaction, Hydro One’s interest in the equity portion of NRLP
partnership units was reduced to 55%, with the Six Nations of the Grand River Development Corporation and the Mississaugas
of the Credit First Nation owning 25% and 20%, respectively, of the equity interest in NRLP partnership units. The First Nations
Partners' noncontrolling interest in NRLP is classified within equity.

1 On October 31, 2024, the Ministry of Infrastructure announced that it has developed a program to deliver up to $400 million in subsidies to internet service providers
(ISPs) for work associated with designated broadband projects. The program is intended to enable ISPs to successfully and safely attach their material and
equipment to the Company’s poles to bring connectivity to rural communities as part of a designated broadband project as defined under Building Broadband Faster
Act (Ontario). A portion of these subsidies is used to reimburse Hydro One Networks on behalf of ISPs for their share of enablement costs incurred to facilitate the
program to date.
2 OCN LP owns and operates electric vehicle fast charging stations across Ontario, under the Ivy Charging Network brand.
Sales to and purchases from related parties are based on the requirements of the OEB’s Affiliate Relationships Code.
Outstanding balances as at period end are interest-free and settled in cash. Invoices are issued monthly, and amounts are due
and paid on a monthly basis.

Capital Contributions
Hydro One enters into contracts governed by the OEB Transmission System Code when a transmission customer requests a
new or upgraded transmission connection. The customer is required to make a capital contribution to Hydro One based on the
shortfall between the present value of the costs of the connection facility and the present value of revenues. The present value of
revenues is based on an estimate of load forecast for the period of the contract with Hydro One. Once the connection facility is
commissioned, in accordance with the OEB Transmission System Code, Hydro One will periodically reassess the estimated load
forecast which will lead to a decrease, or an increase in the capital contributions from the customer. The increase or decrease in
capital contributions is recorded directly to property, plant and equipment in service. In 2024, there were $2 million capital
contributions from these assessments (2023 - $2 million).

Legal Proceedings
Hydro One is involved in various lawsuits and claims in the normal course of business. In the opinion of management, the
outcome of such matters will not have a material adverse effect on the Company’s consolidated financial position, results of
operations or cash flows.
Transfer of Assets
The transfer orders by which the Company acquired certain of Ontario Hydro’s businesses as of April 1, 1999 did not transfer title
to some assets located on Reserves (as defined in the Indian Act (Canada)). Currently, the OEFC holds these assets. Under the
terms of the transfer orders, the Company is required to manage these assets until it has obtained all consents necessary to
complete the transfer of title of these assets to itself. The Company cannot predict the aggregate amount that it may have to pay,
either on an annual or one-time basis, to obtain the required consents. In 2024, the Company paid $2 million (2023 - $nil) in
respect of consents obtained for a permit that was issued in favour of the Company which would allow for the transfer of assets.
In 2024, the Company recorded $4 million (2023 - $3 million) in respect of annual obligations under existing agreements, which
includes assets that continued to be held by OEFC. If the Company cannot obtain the required consents, the OEFC will continue
to hold these assets for an indefinite period of time. If the Company cannot reach a satisfactory settlement, it may have to
relocate these assets to other locations at a cost that could be substantial or, in a limited number of cases, to abandon a line and
replace it with diesel-generation facilities. The costs relating to these assets could have a material adverse effect on the
Company’s results of operations if the Company is not able to recover them in future rate orders.

provided by Hydro One to ONroute relating to OCN LP (OCN Guarantee) and $5 million relating to Aux Energy Inc.
Retirement Compensation Arrangements
Bank letters of credit have been issued to provide security for Hydro One Inc.’s liability under the terms of a trust fund
established pursuant to the supplementary pension plan for eligible employees of Hydro One Inc. The supplementary pension
plan trustee is required to draw upon these letters of credit if Hydro One Inc. is in default of its obligations under the terms of this
plan. Such obligations include the requirement to provide the trustee with an annual actuarial report as well as letters of credit
sufficient to secure Hydro One Inc.’s liability under the plan, to pay benefits payable under the plan and to pay the letter of credit
fee. The maximum potential payment is the face value of the letters of credit.
Prudential Support
Purchasers of electricity in Ontario, through the IESO, are required to provide security to mitigate the risk of their default based
on their expected activity in the market. The IESO could draw on these guarantees and/or letters of credit if these purchasers fail
to make a payment required by a default notice issued by the IESO. The maximum potential payment is the face value of any
letters of credit plus the amount of the parental guarantees.

32. SEGMENTED REPORTING
The Company has three reportable segments: Transmission, Distribution, and Other. The composition of these segments is
described in Note 1 to the consolidated financial statements.
The designation of segments has been based on a combination of regulatory status and the nature of the services provided.
Operating segments of the Company are determined based on information used by the CODM in deciding how to allocate
resources and evaluate the performance of each of the segments. Hydro One’s CODM consists of its Chief Executive Officer and
certain members of the executive leadership team. The CODM evaluates segment performance based on income before
financing charges and income tax expense from continuing operations (excluding certain allocated corporate governance costs)
(EBIT). The CODM considers the key components of EBIT to understand the variances to prior period on a quarterly basis and
measures them against the Company’s budget and forecast across each of the three segments on a monthly basis in order to
properly allocate resources between and within the operating segments.
