ELECTRICITY INDUSTRY OVERVIEW

General Overview

The electricity industry is made up of businesses that generate, transmit, distribute and sell electricity. While traditionally a mature and stable industry, the electricity industry is facing rapid and dramatic technological change and increasing innovation. Hydro One’s business is focused on the transmission and distribution of electricity.

•Transmission refers to the delivery of electricity over high voltage lines, typically over long distances, from generating stations to local areas and large industrial customers.

•Distribution refers to the delivery of electricity over low voltage lines to end users such as homes, businesses and institutions.

Overview of an Electricity System

The basic configuration of a typical electricity system, showing electricity generation, transmission and distribution, is illustrated in the following diagram:

overiewa.jpg

Note:
The above image shows a typical electricity system with transmission-connected generation.

Transmission and distribution networks are sometimes referred to as the “electricity grid” or simply “the grid”.

THE ELECTRICITY INDUSTRY IN ONTARIO

Regulation of Transmission and Distribution

General

The Electricity Act and the Ontario Energy Board Act establish the general legislative framework for Ontario’s electricity market. The activities of transmitters and distributors in Ontario are overseen by three main regulatory authorities: (i) the OEB, (ii) the IESO, and (iii) the Canadian Energy Regulator. The Minister of Energy is responsible for developing long-term energy plans and has the power to issue directives to the IESO and the OEB regarding implementation of such plans.

Ontario Energy Board

The OEB is an independent regulatory agency. The Ontario Energy Board Act provides the OEB with the authority to regulate Ontario’s electricity market, including the activities of transmitters and distributors.

The OEB has the following legislated objectives in relation to the electricity industry:

•to inform consumers and protect their interests with respect to prices and the adequacy, reliability and quality of electricity service,

•to promote economic efficiency and cost effectiveness in the generation, transmission, distribution, sale and demand management of electricity and to facilitate the maintenance of a financially viable electricity industry,

•to promote electricity conservation and demand management in a manner consistent with the policies of the Province, including having regard to the consumer’s economic circumstances, and

•to facilitate innovation in the electricity sector.

The OEB is responsible for, among other things, approving transmission and distribution rates in Ontario. It also approves the construction, expansion, or reinforcement of transmission lines greater than two kilometres in length, as well as mergers, acquisitions, amalgamations and divestitures involving distributors, transmitters and other entities which it licenses. The activities of transmitters and distributors are subject to the conditions of their licences and a number of industry codes issued by the OEB. These codes and other requirements prescribe minimum standards of conduct and service for licensed participants in the electricity market.

In December 2017, the OEB posted its Strategic Blueprint: Keeping Pace with the Evolving Energy Sector, setting out the OEB’s commitment to modernize its approach to regulation over the next five years and established the Advisory Committee on Innovation (“ACI”). The ACI was tasked with
13

identifying steps to develop a modern regulatory framework in response to technological changes occurring in the energy sector. In 2019, in response to recommendations made by the ACI, the OEB initiated two consultation processes, Utility Remuneration and Responding to Distributed Energy Resources (“DERs”). In March 2021, the OEB issued a letter which renamed and consolidated these two consultations into a single consultation named Framework for Energy Innovation: Distributed Resources and Utility Incentives (“FEI”). The FEI consultation focused on: (i) investigating and supporting utilities’ use of DERs they do not own as alternatives to traditional wires solutions to meet distribution needs; and (ii) ensuring that utilities’ planning is appropriately informed by DER penetration and forecasts. In January 2023, the OEB released its Framework for Energy Innovation: Setting a Path Forward for DER Integration report. This report is the culmination of the FEI consultation and sets out the OEB’s policies and next steps with respect to the integration of DERs into distribution system planning and operations, as well as the use of DERs by electricity distributors as non-wires alternatives. In April 2023, the OEB released an Energy Transition Roadmap as part of its 2023-26 Business Plan that provides a schedule of initiatives the OEB is taking or plans to undertake with respect to the energy transition. The Energy Transition Roadmap is intended to provide clarity on the OEB’s priorities, support the coordination of interrelated initiatives within the OEB and across the sector and support effective stakeholder engagement.

In November 2023, the Minister of Energy issued a Letter of Direction to the OEB, which included the Minister of Energy’s priorities and expectations for the OEB over the next 12 months. The government’s priorities are expected to be incorporated in the OEB’s next business plan. A number of initiatives have been identified that will support implementation of the plan contained in the Province’s recent Powering Ontario’s Growth report, which was released in July 2023. The report outlines actions to support the economic growth, decarbonization and ongoing transformation of Ontario’s electricity system. The letter also indicated that additional initiatives may be forthcoming following the publication of the Electrification and Energy Transition Panel’s report. The Electrification and Energy Transition Panel report was released on January 19, 2024. See “The Electricity Industry in Ontario – Issues Affecting the Electricity Industry Generally – Ontario 2017 Long-Term Energy Plan” for more information.

IESO

The IESO delivers key services across the electricity sector, including managing the power system in real time, planning for Ontario’s future energy needs, enabling conservation and designing a more efficient electricity marketplace to support sector evolution. Transmitters and other wholesale market participants must comply with the Market Rules issued by the IESO. The Market Rules require transmitters to comply with mandatory North American reliability standards for transmission issued by the NERC and the NPCC. The IESO enforces these reliability standards and coordinates with system operators and reliability agencies in other jurisdictions to ensure energy adequacy and security across the interconnected bulk electricity system in North America.

In December 2022, the IESO released its Pathways to Decarbonization report in response to the Minister of Energy’s request to evaluate a moratorium on new natural gas generation in Ontario, and to develop an
14

achievable pathway to decarbonization in the electricity system.

In November 2023, the IESO launched an engagement initiative on the development of a Transmitter Selection Framework. The Transmitter Selection Framework is consistent with the IESO’s Pathways to Decarbonization report that recommends building on existing actions to ensure Ontario is positioned to build the electricity generation, storage and transmission necessary to maintain a reliable, affordable and clean electricity system and power the province’s growth beyond 2030. See “Business of Hydro One – Transmission Business Segment – Competitive Conditions” for more information on the Transmitter Selection Framework.

Canadian Energy Regulator

In August 2019, the Canadian Energy Regulator Act came into force, replacing the National Energy Board Act. As a result of the new statute, the National Energy Board became the Canadian Energy Regulator. Any decision or order made by the National Energy Board is considered to have been made under the Canadian Energy Regulator Act and may be enforced as such.

The Canadian Energy Regulator has jurisdiction over the construction and operation of international power lines, as well as interprovincial lines that are designated as being under federal jurisdiction (of which there are currently none). As Hydro One owns and operates 11 active international power lines connecting Ontario’s transmission system with transmission systems in Michigan, Minnesota and New York, Hydro One holds several certificates and permits with the Canadian Energy Regulator.

Transmission

Transmission companies own and operate transmission systems that deliver electricity over high voltage lines. Hydro One owns and operates a transmission system that accounts for approximately 92% of Ontario’s transmission capacity, based on the network component of the revenue requirement1 approved by the OEB.2 The Company’s transmission system is interconnected to systems in Manitoba, Michigan, Minnesota, New York and Quebec and is part of the North American electricity grid’s Eastern Interconnection. The Eastern Interconnection is a contiguous electricity transmission system that extends from Manitoba to Florida and from east of the Rocky Mountains to the North American east coast. Being part of the Eastern Interconnection provides benefits to Ontario, such as greater security and stability for Ontario’s transmission system, emergency support when there are generation constraints or shortages in Ontario, and the ability to exchange electricity with other jurisdictions.

1 The network component of the revenue requirement is Hydro One’s portion of the transmission revenue requirement attributed to assets that are used for the common benefit of all Hydro One and non-Hydro One customers in the province.

2    Hydro One owns and operates approximately 95% of the transmission system in Ontario when based on the total OEB approved revenue requirement.
15

Distribution

Distributors own and operate distribution systems that deliver electricity over power lines at voltages of 50 kV or less to end users. A local distribution company is responsible for distributing electricity to customers in its OEB-licensed service territory, and in some cases to other distributors. A service territory may cover large portions or all of a particular municipality, or an otherwise defined geographic area. Distribution customers include homes, commercial and industrial businesses and institutions such as governments, schools and hospitals.

In Ontario, as per the OEB’s 2022 Yearbook of Electricity Distributors, as at December 31, 2022, 55 local distribution companies provided electricity to over five million customers. The distribution industry in Ontario is fragmented, with the 10 largest local distribution companies accounting for approximately 82% of the province’s customers.

Through its wholly-owned subsidiary, Hydro One Inc., Hydro One owns the largest local distribution business in Ontario, which serves approximately 1.5 million predominantly rural customers, or approximately 27% of the total number of customers in Ontario.

Issues Affecting the Electricity Industry Generally

Tax Incentives

Tax incentives were included in the 2015 Ontario budget to promote consolidation in the electricity distribution sector. The 2015 Ontario budget announced a reduction in the tax rate for transfers of electricity assets from 33% to 22% and to nil for distributors with fewer than 30,000 customers. In addition, the budget introduced a capital gains exemption where capital gains arise as a result of exiting the payments in lieu of corporate taxes regime. These incentives are in place until December 31, 2024.

Tax incentives were included in the 2023 federal budget to build Canada’s clean economy and to promote a shift in support of Canada’s net-zero goal. The Clean Technology ITC and the Clean Electricity ITC were two of the tax measures included in the 2023 federal budget. The Clean Technology ITC provides a 30% refundable tax credit on new eligible projects, subject to certain conditions. The Clean Electricity ITC provides a 15% refundable tax credit on eligible investments in new projects and the refurbishment of existing facilities. The Clean Technology ITC is available for projects from March 28, 2023, and will be phased out after 2034, with the investment tax credit rate being reduced for 2034 and nil thereafter. The Clean Electricity ITC would be available for projects from the 2024 budget date to 2034.

Ontario 2017 Long-Term Energy Plan

In October 2017, the Province released its 2017 Long-Term Energy Plan (the “2017 Long-Term Energy Plan”), which set out a number of initiatives for Ontario’s energy system. The IESO and the OEB developed implementation plans in support of the objectives of the 2017 Long-Term Energy Plan, and
16

each implementation plan was approved by the Minister of Energy in February 2018. The Province continues to consult industry and stakeholders on a long-term system-planning process to replace the 2017 Long-Term Energy Plan.

In 2022, the Province established the Electrification and Energy Transition Panel (the “Electrification and Energy Transition Panel”). This panel is responsible for advising the Province on the highest value short, medium, and long-term opportunities for the energy sector to help Ontario’s economy prepare for electrification and the energy transition. The Electrification and Energy Transition Panel is also expected to identify opportunities to strengthen Ontario’s long-term energy planning process by better coordinating the fuels and the electricity sector. In 2023, the Electrification and Energy Transition Panel invited stakeholders, Indigenous partners and the public to provide written advice on five themes related to energy transition and electrification. These engagements assisted the Electrification and Energy Transition Panel in preparing its report, which was released on January 19, 2024.

OEB Actions on Electricity Pricing

Since March 2020, the Province has taken a number of actions related to the pricing of electricity to support regulated price plan (“RPP”) customers in dealing with the impacts of the COVID-19 pandemic. These government-mandated actions include providing different fixed electricity prices for various periods of time. In response to direction provided by the Province, in September 2020 the OEB announced that, as of October 13, 2020, all utilities were required to give RPP customers the choice to opt out of time-of-use pricing and to elect instead to be charged on the basis of tiered (or fixed) electricity pricing.

In November 2020, the Province released its 2020 Ontario Budget: Ontario’s Action Plan: Protect, Support, Recover (the “2020 Ontario Budget”), which included a rate mitigation plan to help certain business and industrial customers. As of January 1, 2021, a portion of non-hydro renewable energy contracts (including wind, solar, bioenergy) is funded by the Province and not ratepayers. According to the 2020 Ontario Budget, this represented an approximately 25% reduction in Global Adjustment. The Global Adjustment is the difference between the guaranteed price and the money the generators earn in the wholesale marketplace.

On December 15, 2020, the OEB reset the RPP prices effective January 1, 2021, to reflect a decrease in the RPP supply cost as a result of the reduction in the Global Adjustment as set out in the 2020 Ontario Budget. These RPP prices came into effect at the conclusion of the electricity price changes established to assist customers in dealing with the impacts of the COVID-19 pandemic. In April 2021, the OEB reset the RPP prices effective May 1, 2021 for households and small businesses. In October 2021, the OEB announced that as of November 1, 2021, the electricity prices would not change under the RPP. In January 2022, the OEB temporarily changed the RPP prices for the period from January 18, 2022 to February 7, 2022, fixing the price for this period to the off-peak rate in order to provide temporary electricity rate relief as directed by the Province. In October 2022, the OEB reset the RPP prices effective November 1, 2022 for households and small businesses.
17


Resulting from established regulatory requirements by the Province in 2022, the OEB required distributors to implement a new voluntary ultra-low overnight price plan for RPP customers effective November 1, 2023. This represents a third pricing option for RPP customers in addition to time-of-use and tiered pricing plans. The ultra-low overnight price plan supports electrification and decarbonization by incentivizing customers to shift electricity loads to overnight periods when demand is lower and more electricity from non-emitting sources is available. In April 2023, the OEB released an addendum to their RPP Price Report that established the electricity prices under the ultra-low overnight price plan for May 1, 2023 to October 31, 2023. In September 2023, Hydro One launched the new ultra-low overnight price plan and began offering the new ultra-low overnight price plan to eligible customers. In October 2023, the OEB updated the RPP prices (including the new ultra-low overnight prices) for households and small businesses effective November 1, 2023. Going forward, it is anticipated that the OEB will periodically review the RPP prices and will reset them if required, in accordance with the OEB’s usual practice.

Building Broadband Faster Act, 2021

In March 2021, the Province introduced Bill 257, Supporting Broadband and Infrastructure Expansion Act, 2021, to create a new act entitled the Building Broadband Faster Act, 2021 that is aimed at supporting the timely deployment of broadband infrastructure within unserved and underserved rural Ontario communities. Bill 257, which received Royal Assent in 2021, amended the Ontario Energy Board Act to provide the Province with regulation-making authority regarding the development of, access to, or use of electricity infrastructure for non-electricity purposes. The Building Broadband Faster Act Guideline and three regulations informing the legislative changes were published in 2021. In March 2022, the Province introduced Bill 93, Getting Ontario Connected Act, 2022. Bill 93, which received Royal Assent in 2022, amended the Building Broadband Faster Act 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. A regulation regarding electricity infrastructure and designated broadband projects under the Ontario Energy Board Act came into force in April 2022. This regulation substantially adopted Hydro One’s proposed approach to allocation of the costs of broadband-related work on utility assets. It also directed the OEB to establish a deferral account for rate-regulated distributors to record incremental costs associated with carrying out activities pertaining to designated broadband projects, which the OEB completed in July 2022. This regulation was amended in March 2023 with respect to performance timelines associated with 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.

In August 2023, the Building Broadband Faster Act Guideline was further amended to provide 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.

18

The Company continues to be engaged with the Province and the OEB on implementing an appropriate regulatory framework to support the published Building Broadband Faster Act Guideline and regulations, including arrangements to sustain the Company’s revenues and recovery of reasonable associated costs.

Legislative Provisions Specific to Hydro One

In addition to legislation in Ontario that impacts all transmitters and distributors, there is legislation that is specific to Hydro One. Specifically, the Electricity Act requires Hydro One’s head office and principal grid control centre to be maintained in Ontario, restricts the disposition of substantially all of its OEB-regulated transmission or distribution business, prohibits any change to its jurisdiction of incorporation, requires the Company to have an ombudsman, contains a 10% ownership restriction with respect to Voting Securities and restricts the Province from selling Voting Securities if it would own less than 40% of the Voting Securities of any class or series as a result of the sale.

Ombudsman

The Electricity Act requires the Company to have an ombudsman to act as a liaison with customers and to establish procedures for the ombudsman to inquire into and report to the Board on matters raised with the ombudsman by or on behalf of customers. See “Business of Hydro One – Ombudsman” for more information.

10% Ownership Restriction

The Electricity Act imposes share ownership restrictions on the 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 (the “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. The articles of Hydro One Limited provide for comprehensive enforcement mechanisms that are applicable in the event of a contravention of the Share Ownership Restrictions.

Maintenance of 40% Ownership

As of December 31, 2023, the Province owned approximately 47.1% of Hydro One Limited’s common shares. See the Annual MD&A under the heading “Risk Management and Risk Factors” for more information.

The Electricity Act restricts the Province from selling Voting Securities (including common shares of Hydro One Limited) if it would own less than 40% of the outstanding number of Voting Securities of that class or series after the sale. If as a result of the issuance of additional Voting Securities by Hydro One
19

Limited, the Province owns less than 40% of the outstanding number of Voting Securities of any class or series, the Province must, subject to the approval of the Lieutenant Governor in Council and the necessary appropriations from the Legislature, take steps to acquire as many Voting Securities of that class or series as are necessary to increase the Province’s ownership to not less than 40% of the outstanding number of Voting Securities of that class or series. The manner in which, and the time by which, the Province must acquire these additional Voting Securities will be determined by the Lieutenant Governor in Council.

The Province has been granted pre-emptive rights by Hydro One Limited to assist it in meeting its ownership requirements under the Electricity Act as described under “Agreements with Principal Shareholder – Governance Agreement – Other Matters – Pre-emptive Rights”.

Hydro One Accountability Act

As of January 1, 2023, the provisions of the Hydro One Accountability Act requiring a compensation framework and the related directive are no longer in effect. The framework set out certain requirements for compensation for the Board, CEO and certain other executives. Additional information regarding Hydro One’s compensation arrangements is found in the Company’s management information circular for its most recent annual meeting of shareholders.

Elimination of Certain Legislation With Respect to Hydro One

In 2015 and 2016, Hydro One Inc. and its subsidiaries ceased to be subject to a number of Ontario statutes that apply to entities owned by the Province. Hydro One Limited is similarly not subject to those statutes. Notwithstanding the elimination of certain legislation with respect to Hydro One, the Company is required under the Financial Administration Act and the Auditor General Act to provide financial information to the Province for the Province’s public reporting purposes.

Cybersecurity

The Company is exposed to potential risks related to cyberattacks, supply chain compromises and unauthorized access to our systems. As the Company continues to make investments in and rely on additional, more complex and interconnected digital technology to enable efficient operations, the likelihood of a cyber-breach impacting our business increases. In addition, the critical nature of our business further increases the likelihood of a sophisticated cyber attacker taking advantage of our people, processes and technology. The Company takes a risk-aligned approach to cyber related investments to reduce the likelihood of an impactful cyber related breach. Despite having strong security measures in place, a breach could occur. A breach has the ability to corrupt our information technology systems, compromise our sensitive information, effect the integrity of our financial controls, disrupt operations or have impacts to the safety of our work environment. The Company manages these risks by establishing a common set of cybersecurity standards, periodic security testing, program maturity objectives, security partnerships and a unified security strategy built on a set of cybersecurity standards driven by the OEB. This Ontario specific set of standards is in alignment with the National Institute of Standards and
20

Technology’s Cyber Security Framework. In addition to provincial regulatory requirements of the OEB, critical systems that support the North American Bulk Electric System are regulated by the North American Electric Reliability Critical Infrastructure Protection Standards. These two foundational frameworks establish strong security measures across all aspects of our operations.

Exemptive Relief

Disclosure of Ownership by the Province

In July 2022, the Canadian securities regulatory authorities granted (i) the Minister of Energy; (ii) Ontario Power Generation Inc. (on behalf of itself and the segregated funds established as required by the Nuclear Fuel Waste Act); and (iii) agencies of the Crown, provincial Crown corporations and other provincial entities (collectively, the “Non-Aggregated Holders”) exemptive relief, subject to certain conditions, to enable each Non-Aggregated Holder to treat securities of Hydro One Limited and debt securities of Hydro One Inc. and HOHL that it owns or controls separately from securities of Hydro One Limited and debt securities of Hydro One Inc. and HOHL owned or controlled by the other Non-Aggregated Holders for purposes of certain take-over bid, early warning reporting, insider reporting and control person distribution rules and certain distribution restrictions under Canadian securities laws. Hydro One Limited was also granted relief permitting it to rely solely on insider reports and early warning reports filed by Non-Aggregated Holders when reporting beneficial ownership or control or direction over securities of Hydro One Limited and debt securities of Hydro One Inc. and HOHL in any information circular or annual information form in respect of such securities beneficially owned or controlled by any Non-Aggregated Holder, subject to certain conditions. This exemptive relief will remain in effect until the earliest to occur of the following: (i) July 28, 2027, and (ii) the date that the Non-Aggregated Holders becomes subject to disclosure requirements that are substantially similar to the disclosure requirements regarding beneficial ownership or control over securities of Hydro One Limited or debt securities of Hydro One Inc. or HOHL for which such exemption was granted and such disclosure requirements require the aggregation of holdings by the Minister of Energy with other Non-Aggregated Holders. Substantially similar relief had previously been granted in June 2017, which terminated in 2022.

U.S. GAAP

In October 2022, Hydro One Limited was granted exemptive relief by the securities regulators in each province and territory of Canada that allows Hydro One Limited to continue to report its financial results in accordance with U.S. GAAP (the “Exemptive Relief”). The Exemptive Relief will remain in effect until the earliest to occur of the following: (i) January 1, 2027; (ii) if Hydro One Limited ceases to have rate-regulated activities, the first day of Hydro One Limited’s financial year that commences after it ceases to have such rate-regulated activities; and (iii) the first day of Hydro One Limited’s financial year that commences on or following the later of: (a) the effective date prescribed by the IASB for the mandatory application of a standard within International Financial Reporting Standards specific to entities with rate-regulated activities (the “Mandatory Rate-regulated Standard”); and (b) two years after the IASB publishes the final version of a Mandatory Rate-regulated Standard. In January 2021, the IASB
21

published Exposure Draft – Regulatory Assets and Liabilities (the “Exposure Draft”). The effective date for mandatory application of the eventual final standard, if any, is not yet determinable and the Company continues to monitor the developments of the Exposure Draft and determine the potential impacts to the Company’s financial statements.

Hydro One Limited is also permitted to report its financial results in accordance with U.S. GAAP by virtue of being, and for so long as it remains, an “SEC issuer” (within the meaning of National Instrument 52-107 – Acceptable Accounting Principles and Auditing Standards). There can be no assurance that Hydro One Limited will remain an SEC issuer indefinitely.

RATE-REGULATED UTILITIES

Rate Applications in Ontario

Framework

The term “rate-regulated” is used to refer to an electricity business whose rates for transmission, distribution and other services are subject to approval by a regulator. The rate base of a rate-regulated utility means the net book value of the regulated assets of the utility, plus an allowance for working capital. The OEB is the regulator that approves electricity transmission and distribution rates in Ontario. Transmission and distribution rates have historically been determined using either a cost-of-service model or a performance-based model, which typically includes a cost-of-service base year. These models are reviewed and modified by the OEB from time to time.

In a cost-of-service model, a utility charges rates for its services that allow it to recover the costs of providing its services and earn an allowed return on equity. A utility’s return on equity, or “ROE”, is the rate of return that a regulator allows the utility to earn on the equity portion of the utility’s rate base. The utility’s costs of providing its services must be prudently incurred. Cost savings are typically passed on to
22

customers in the form of lower rates reflected in future rate decisions.

Cost of Service ($)
+Return on Equity ($)=
Revenue Requirement ($)

In a performance-based model, a utility also charges rates for its services that allow it to recover the costs of providing its services and earn an allowed return on equity. However, rates are adjusted formulaically in years subsequent to the initial rebasing of costs. The formulaic adjustments in a performance-based model consider inflation and expectations regarding productivity. They assume that the utility becomes increasingly efficient over time. If a utility achieves cost savings in excess of those established by the regulator, the utility may retain some or all of the benefits of those cost savings, which may permit the utility to earn more than its allowed return on equity. In Ontario, transmission and distribution rates, including those of Hydro One, are now generally determined using a performance-based model.

November 20, 2023, seeking OEB approval of the acquisition of Chapleau Public Utilities Corporation’s distribution assets.

Transmission Line Projects in Northeast and Eastern Ontario

In October 2023, the Minister of Energy directed the OEB to amend Hydro One Networks’ transmission licence to develop and seek approvals for three new priority transmission lines. In November 2023, the OEB amended Hydro One Networks’ transmission licence to include:

•Mississagi to Third Line – an approximately 75 kilometre, 230 kV transmission line between Mississagi TS and Third Line TS;
•Hanmer to Mississagi Line – an approximately 205 kilometre, 500 kV transmission line between Hanmer TS and Mississagi TS; and
•Greater Toronto Area East Line – an approximately 50 kilometre, 230 kV transmission line between either Cherrywood TS or Clarington TS and Dobbin TS.

Through Hydro One’s equity partnership model, First Nations have the opportunity to invest in a 50% equity stake in the transmission line component of the three priority transmission lines once complete. See “General Development of the Business – Chronological Development of the Business – 2022 – Equity Partnership Model with First Nation Communities” and see “Business of Hydro One – Indigenous Communities” for more information on the Equity Partnership with First Nations.

COVID-19 and Related Developments

In 2023, the World Health Organization declared the end to COVID-19 as a public health emergency, which was originally declared a global pandemic in 2020. During the pandemic, the Company had continued to operate in-line with evolving safety procedures and practices.

Hydro One has not been immune to the global supply chain disruptions and pricing pressures that were experienced across the utility industry. However, it has managed these disruptions by shifting projects and taking proactive measures to ensure it has the materials and equipment necessary to complete its capital work program. As a result, there has not been a material impact to the overall work program.

General Development of the Business

In addition to the chronological development of the business, the following general developments in the business have occurred and continue to be relevant.

Customer Focus

Hydro One’s continued focus on customer service remains a critical aspect of its success as a company. Greater corporate accountability for performance outcomes, and company-wide improvements in
29

productivity and efficiency, align with customers’ expectations of how Hydro One should operate. Hydro One intends to continue to offer affordable and reliable electricity, advocate for its customers and empower them to make informed decisions about their energy usage and respond to emerging customer needs.

Customer Service

Hydro One is committed to delivering value to its customers by understanding customers’ current and future needs and expectations so that the Company can continuously improve its service. This includes specific, measurable commitments that encompass all areas of service. In 2023, residential and small business customer satisfaction scores remained unchanged from 2022 at 87%, transmission customer satisfaction also remained unchanged from 2022 at 88%, and commercial and industrial satisfaction increased from 2022 from 74% to 82%.

Hydro One is on a multi-year journey to transform the customer experience by continuing to invest in technology such as interaction analytics, home energy insights, and automated performance scorecards for contact service representatives.

Review of Operations

Hydro One is committed to providing value to its customers and shareholders by identifying and acting on opportunities to become the safest and most efficient utility. Hydro One has been focused on the identification of opportunities for improved corporate performance and the development of strategies to drive safer, more efficient and cost-effective operations. Hydro One conducts regular reviews of key corporate activities and programs, covering areas such as construction services and project management practices, asset deployment and controls, asset planning, information technology and cybersecurity, vegetation management practices, fleet services and utilization, supply chain management and business continuity planning. The Company has and continues to observe and implement operational and cost improvements across work planning and execution.

Strategy

In November 2019, Hydro One released its updated corporate strategy which reaffirms the Company’s commitment to Ontario and the provision of safe, reliable and affordable electricity. The strategy focuses on five key aspirational priorities:

•Plan, Design And Build A Grid For The Future
We will plan, design and build a reliable grid taking into account changing technologies to prevent future outages. There will be increased focus on grid resilience in order to restore power after events. Climate change and sustainability factors will be taken into consideration in our planning processes to increase resilience and lower our environmental footprint. We will incorporate distributed energy resources to enable customer choice while delivering exceptional
30

value to customers through best-in-class asset management practices.

•Be The Safest And Most Efficient Utility
We will transform and improve our safety culture through robust safety analytics as well as grass-roots engagement with our employees. Field operations will be more empowered to drive efficiency, productivity and reliability and provided with efficient corporate support. There will be a focus on efficient capital delivery to support an ongoing growing work program.

•Be A Trusted Partner

BUSINESS OF HYDRO ONE

Segments

Through its wholly-owned subsidiary Hydro One Inc., Hydro One is Ontario’s largest electricity transmission and distribution utility with approximately $33 billion in assets and 2023 revenues of approximately $7.8 billion. Hydro One owns and operates substantially all of Ontario’s electricity transmission network and is the largest electricity distributor in Ontario by number of customers. The Company’s regulated transmission and distribution operations are owned by subsidiaries of Hydro One Inc. Hydro One delivers electricity safely and reliably to approximately 1.5 million customers across the province of Ontario, and to large industrial customers and municipal utilities. Through its subsidiaries, Hydro One Inc. owns and operates approximately 30,000 circuit kilometres of high-voltage transmission lines and approximately 125,000 circuit kilometres of primary low-voltage distribution lines.

Hydro One has three segments: (i) transmission business; (ii) distribution business; and (iii) other. Each of the three segments is described below.

Hydro One’s transmission and distribution businesses are both operated primarily by Hydro One Networks. This allows both businesses to utilize common operating platforms, technology, work processes, equipment and field staff and thereby take advantage of operating efficiencies and synergies. For regulatory purposes, Hydro One Networks has historically filed separate rate applications with the OEB for each of its licensed transmission and distribution businesses. In 2021, a single application was filed for the Hydro One Networks transmission and distribution businesses for the period 2023 to 2027, which was approved by the OEB in November 2022. See “Transmission Business Segment – Regulation – Transmission Rate Setting” for more information.

Transmission Business Segment

Overview

Hydro One’s transmission business consists of owning and operating Hydro One’s transmission system, which accounts for approximately 92% of Ontario’s transmission capacity based on the network component of the revenue requirement3 approved by the OEB.4 All of the Company’s transmission business is carried out by subsidiaries of Hydro One Inc., including through Hydro One Networks and HOSSM, as well as through the Company’s approximately 66% interest in B2M Limited Partnership and approximately 55% interest in NRLP. Hydro One’s transmission business represented approximately 60% of its total assets as at December 31, 2023, and accounted for approximately 53% of its total revenues, net of purchased power
3 The network component of the revenue requirement is Hydro One’s portion of the transmission revenue requirement attributed to assets that are used for the common benefit of all Hydro One and non-Hydro One customers in the province.

5 in 2023 and approximately 28% of its total revenues in 2023, and approximately 51% of its total revenues, net of purchased power in 2022 and approximately 26% of its total revenues in 2022.

The Company’s transmission business is a rate-regulated business that earns revenues mainly from transmission rates that are subject to approval by the OEB. Transmission rates are generally determined using a performance-based model, which typically includes a cost-of-service base year. Transmission rates are administered and collected by the IESO and are remitted by the IESO to Hydro One on a monthly basis, which means that Hydro One’s transmission business has no direct exposure to end-customer counterparty risk.

Transmission rates are based on monthly peak electricity demand across Ontario’s transmission network. This gives rise to seasonal variations in Hydro One’s transmission revenues, which are generally higher in the summer and winter due to increased demand, and lower during other periods of reduced demand. Hydro One’s transmission revenues also include revenues associated with exporting energy to markets outside of Ontario. Ancillary revenue includes revenues from providing maintenance services to generators and from third-party land use.

Business

The Company’s transmission system serves substantially all of Ontario and transported approximately 137 TWh of energy throughout the province in 2023. Hydro One’s transmission customers consist of 35 local distribution companies (including Hydro One’s own distribution business) and 87 large industrial customers connected directly to the transmission network, including automotive, manufacturing, chemical and natural resources businesses. Electricity delivered over the Company’s transmission network is supplied by 135 generators in Ontario and electricity imported into the province through interties. Interties are transmission interconnections between neighbouring electric systems that allow power to be imported and exported.

The high voltage power lines in Hydro One’s transmission network are categorized as either lines which form part of the “bulk electricity system” or “area supply lines”. Power lines which form part of the bulk electricity system typically connect major generation facilities with transmission stations and often cover long distances, while area supply lines serve a local region. Ontario’s transmission system is connected to the transmission systems of Manitoba, Michigan, Minnesota, New York and Quebec through the use of interties, allowing for the import and export of electricity to and from Ontario.

Hydro One’s transmission assets were approximately $20 billion as at December 31, 2023 and include

transmission stations, transmission lines, a control centre and telecommunications facilities. Hydro One has approximately 309 in-service transmission stations and approximately 30,000 circuit kilometres of high voltage lines whose major components include cables, conductors and wood or steel support structures. All of these lines are overhead power lines except for approximately 270 circuit kilometres of underground cables located in primarily urban areas.

Hydro One’s transmission network is managed from a central location. This centre monitors and controls the Company’s entire transmission network and has the capability to remotely monitor and operate transmission equipment, respond to alarms and contingencies and restore and reroute interrupted power. There is also a backup facility which would be staffed in the event of an evacuation of the centre. In 2022, Hydro One’s new primary control centre became fully operational.

Hydro One uses telecommunications systems for the protection and operation of its transmission and distribution networks. These systems are subject to very stringent reliability and security requirements, which help the Company meet its reliability obligations and facilitate the restoration of power following service interruptions.

B2M Limited Partnership is Hydro One’s partnership with the Saugeen Ojibway Nation with respect to the Bruce-to-Milton transmission line. B2M Limited Partnership owns the transmission line assets relating to two circuits between Bruce TS and Milton Switching Station. Hydro One Networks owns the stations where the lines terminate. Hydro One maintains and operates the Bruce-to-Milton line and has an approximately 66% economic interest in the partnership. See “Business of Hydro One – Transmission Business Segment – Regulation – Recent Transmission Rate Applications – B2M Limited Partnership” for more information.

NRLP is Hydro One’s partnership with Six Nations of the Grand River Development Corporation and, through a trust, the Mississaugas of the Credit First Nation. NRLP owns the Niagara Line. Hydro One maintains and operates the Niagara Line, and has an approximately 55% interest in the partnership. See “Business of Hydro One – Transmission Business Segment – Regulation – Recent Transmission Rate Applications – Niagara Reinforcement Limited Partnership” for more information.

Regulation

Transmission Rate Setting

The OEB provides two revenue plan options for transmission rates in Ontario: the Custom Incentive Rate Setting Plan (the “Custom IR Method”) and the Incentive-Based Revenue Index Rate Setting Plan (the “Revenue Cap Index”).

Under the Revenue Cap Index, the first year’s revenue requirement reflects the transmitter’s cost of service; and annually thereafter, this amount is subject to a formulaic increase reflecting inflation, partially offset by a productivity factor. The revenue requirement in these subsequent years is set on the
34

assumption that the transmitter will achieve efficiency or productivity improvements to offset the productivity factor imposed by the regulator. Under the Custom IR Method, a similar methodology to the Revenue Cap Index may be used; however, applications are multi-year and are designed to reflect a transmitter-specific revenue trend for the application term. For example, a transmitter may request incremental capital funding beyond amounts established in the base year revenue requirement.

The OEB sets transmission rates based on a two-step process. First, all transmitters apply to the OEB for approval of their revenue requirements. Second, the OEB aggregates the total revenue requirements of all transmitters in Ontario and applies a formula to arrive at a single set of rates that are charged to ratepayers for the three types of transmission services applicable in Ontario, namely: network services, line connection services and transformation connection services. The three separate rates charged for these services are the same for all transmitters and are referred to as “uniform transmission rates”. Uniform transmission rates for all transmitters are set by the OEB on an annual basis, using the revenue requirements set out in the most recent rate decision issued for each transmitter.

The filing requirements for transmitters mandate the integration of core RRF (defined below under “Business of Hydro One – Distribution Business Segment – Regulation – Distribution Rates”) concepts into revenue requirement applications. Transmitters applying for revenue requirements under the Custom IR Method or Revenue Cap Index must include: (i) evidence of the continuous improvement and efficiency gains anticipated to be achieved over the rate term; (ii) a mechanism to protect ratepayers in the event of earnings significantly in excess of the regulatory net income supported by the return on equity established in the approved revenue requirement; and (iii) proposed performance metrics applicable to their individual circumstances. A key component of rate-setting under the RRF is benchmarking evidence to support cost forecasts and system planning proposals.

Recent Transmission Rate Applications

Hydro One Networks, B2M Limited Partnership, HOSSM and NRLP file separate applications to the OEB for the approval of their transmission revenue requirement for transmission services.

Hydro One Networks

In April 2019, Hydro One Networks filed an appeal with the Ontario Divisional Court with respect to the OEB’s 2017 deferred tax asset decision, whereby the OEB concluded that the net deferred tax asset resulting from the transition from the payments in lieu of tax regime under the Electricity Act to the federal and provincial tax regimes in connection with Hydro One Limited’s 2015 initial public offering should be shared with Hydro One Networks’ ratepayers instead of accruing entirely to Hydro One Limited’s shareholders. In the appeal, Hydro One Networks sought allocation to Hydro One Limited’s shareholders of the full amount of the future tax savings arising from the deferred tax asset.

In July 2020, the Ontario Divisional Court rendered its decision and held that the OEB decision was incorrect in law because the OEB had failed to apply the correct legal test. The Ontario Divisional Court
35

set aside the OEB’s decision and held that the deferred tax asset should be allocated to shareholders in its entirety. However, the Ontario Divisional Court concluded that it did not have jurisdiction to substitute its own decision for that of the OEB and, with clear directions as to what the OEB’s decision must be, ordered that the matter be returned to the OEB.

In October 2020, the OEB issued a procedural order to implement the direction of the Ontario Divisional Court and required Hydro One to submit its proposal for the recovery of the deferred tax asset amounts allocated to Hydro One Networks’ ratepayers for the 2017 to 2022 period. In April 2021, the OEB issued its decision and approved recovery of the deferred tax asset 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.

In March 2019, Hydro One Networks filed a three-year custom incentive rate application with the OEB for its 2020-2022 transmission revenue requirements. The application requested the OEB’s approval of revenue requirements of $1,623 million for 2020. In June 2019, Hydro One Networks filed updates to the application reflecting recent financial results and other adjustments.

In April 2020, the OEB issued its decision on Hydro One Networks’ 2020-2022 transmission rate application. In July 2020, the OEB issued its final rate order for the 2020-2022 transmission rates approving a revenue requirement of $1,630 million, $1,701 million and $1,772 million for 2020, 2021 and 2022, respectively.

In July 2020, the OEB issued its decision for the uniform transmission rates. The 2020 uniform transmission rates that were put in place on an interim basis on January 1, 2020 continued for the remainder of 2020 in light of the COVID-19 pandemic.

In December 2020, the OEB issued its decision and order setting the final 2021 uniform transmission rates effective January 1, 2021, which included the approval of a two-year disposition period for Hydro One Networks’ 2020 forgone revenue including interest, beginning on January 1, 2021.

In March 2018, the OEB issued a letter stating that the OEB expected Hydro One Networks to file a joint distribution-transmission rate application for the period from 2023 to 2027. In August 2021, Hydro One Networks filed a custom joint rate application for 2023-2027 (the “JRAP”) which included a proposed investment plan supporting the transmission and distribution revenue requirements. The JRAP requested the OEB’s approval of transmission revenue requirements of $1,823 million for 2023, $1,938 million for 2024, $2,028 million for 2025, $2,140 million for 2026 and $2,219 million for 2027.

In November 2022, the OEB approved the settlement in whole and issued its final rate order for the 2023-2027 transmission rates approving a revenue requirement of $1,952 million, $2,073 million, $2,168 million, $2,277 million, and $2,362 million for 2023, 2024, 2025, 2026, and 2027, respectively. Notwithstanding that the parties to settlement agreed to reduce Hydro One Networks’ proposed capital and operating expenditures, the approved revenue requirement exceeds Hydro One Networks’ proposed
36

revenue requirement due to increases to the OEB’s cost of capital parameters and inflation factor for 2023.

Following the OEB approval of the JRAP and completion of the recovery of deferred tax asset amounts, Hydro One Networks’ effective tax rate over the JRAP period is expected to be between 13% and 16%. See also “Business of Hydro One – Distribution Business Segment – Regulation – Recent Distribution Rate Applications – Hydro One Networks”.

B2M Limited Partnership

In July 2019, B2M Limited Partnership filed a transmission rate application for 2020-2024. On December 9, 2019, B2M Limited Partnership reached a settlement on all issues with OEB staff and intervenors. In January 2020, the OEB approved the settlement agreement effective January 1, 2020, including a 2020 base revenue requirement of $33 million, and a revenue cap escalator index for 2021 to 2024. The transmission rate application is updated annually, and in September 2023, the OEB approved a rate increase of 4.8% effective January 1, 2024.
HOSSM

In 2018, Hydro One completed the operational integration of HOSSM (formerly Great Lakes Power Transmission LP), which was acquired in October 2016.

HOSSM is under a ten-year deferred rebasing period for years 2017-2026, following receipt of approval by the OEB of Hydro One’s acquisition of HOSSM in October 2016. In July 2018, HOSSM filed a 2019 application to allow for inflationary increase (“revenue cap escalator factor”) to its previously approved revenue requirement. The revenue cap escalator factor is designed to add inflationary increases to the revenue requirement on an annual basis. In June 2019, the OEB approved the revenue cap escalator index at 1.1% (net), which was applied to HOSSM’s base revenue requirement for 2019, effective February 1, 2019, and also approved the 2019-2026 revenue cap framework. The revenue requirement is updated annually, and in October 2023, the OEB approved a rate decrease of 2.04% effective January 1, 2024.

Niagara Reinforcement Limited Partnership

In 2018, the NRLP was formed for the purpose of owning a new 230 kV transmission line in the Niagara region (the “Niagara Line”) to enable generators in the Niagara area to connect to load centres of the Greater Toronto and Hamilton areas.

In October 2019, NRLP filed its revenue cap incentive rate application for 2020-2024. In December 2019, the OEB approved NRLP’s proposed 2020 revenue requirement of $9 million on an interim basis effective January 1, 2020. In February 2020, NRLP reached a settlement on all issues, accepting the 2020 base costs and the 2019 incurred costs as presented. The settlement included a 50% reduction to the inflation component and a 0.6% capital adjustment factor to account for a decreasing rate base value. In
37

April 2020, the OEB approved the settlement agreement. The revenue requirement is updated annually, and in September 2023, the OEB approved a rate increase of 2.1% effective January 1, 2024.

Reliability Standards and Regulations for Transmission

The Company’s transmission business is required to comply with various mandatory regulations for transmission reliability, including mandatory standards, directories, market rules, and the Transmission System Code (collectively, the “Reliability Standards”) established by NERC, NPCC, the OEB and the IESO, which are international, regional and Ontario reliability regulatory authorities, respectively, involved in regulating, promoting and otherwise improving the reliability of transmission networks in North America. Hydro One’s compliance with these Reliability Standards is enforced by the OEB, IESO and the Canadian Energy Regulator.

In addition to the currently enforced Reliability Standards, NERC, NPCC, the OEB and IESO continue to develop and issue new and revised Reliability Standards and other regulations, including Critical Infrastructure Protection Standards and Cybersecurity Regulations with which Hydro One and other utilities, owners and operators of the bulk electricity system in North America must comply. Hydro One expects to continue to perform work, and to incur associated costs, in order to achieve, sustain and demonstrate compliance with all of these Reliability Standards. Hydro One anticipates that these costs will be recovered in rates. See the Annual MD&A under the subheadings “Risk Management and Risk Factors – Risks Relating to Hydro One’s Business – Compliance with Laws and Regulations”, “Risk Management and Risk Factors – Risks Relating to Hydro One’s Business – Risk Associated with Information Technology (IT), Operational Technology (OT) Infrastructure and Data Security” and “Risk Management and Risk Factors – Risks Relating to Hydro One’s Business – Risks Relating to Asset Condition, Capital Projects and Innovation” for more information.

Regional Planning

The OEB oversees regional planning processes to ensure that transmission and distribution investments are coordinated at a regional level. One of the OEB objectives for regional planning is to review and/or rely on the recommendations within the regional planning reports to support rate applications submitted by transmitters and distributors and “leave to construct” applications submitted by transmitters. In Ontario, the first and last phases (Needs Assessment and Regional Infrastructural Plan) of the regional planning process are led by the transmitter responsible for a particular geographic region. Hydro One also coordinates with the IESO on its Integrated Regional Resource Planning, which is another phase of the regional planning process. For this purpose, the province is divided into 21 regions. As the largest transmitter in Ontario, Hydro One plays a key role in the regional planning process and is responsible for leading the regional planning process in 20 of the 21 designated regions.

In conducting regional planning, Hydro One works closely with the IESO and all distributors in the region through study teams to jointly identify needs and develop transmission and distribution investment options.
38


In December 2020, the OEB announced that it was initiating a consultation to undertake a review of the regional planning process that applies to Ontario’s electricity sector, to improve the efficiency and effectiveness of the current regional planning process. As a result, the OEB re-established its Regional Planning Process Advisory Group (“RPPAG”), comprised of a number of interested stakeholders, including Hydro One, to assist in its review. In December 2021, the RPPAG provided its report to the OEB with recommendations intended to improve the regional planning process in Ontario. In April 2022, the OEB issued a letter endorsing the recommendations and provided an implementation plan. The RPPAG has made several changes to the regional planning process, all of which have been formally implemented in 2022 and 2023. The changes include updates to OEB filing requirements; updates to CDM guidelines to address potential barriers to CDM measures in regional planning; bulletins clarifying local preference and cost allocation; and new processes to enhance coordination with municipalities and improved load forecasting.

Major Transmission Capital Investment Projects

Hydro One has a portfolio of transmission projects across the province of Ontario. See the Annual MD&A under the subheading “Capital Investments – Major Transmission Capital Investment Projects” for more information on significant transmission projects.

Capital Expenditures

The Company anticipates that it will spend in the range of approximately $1,507 million to $1,998 million per year, over the next four years, on capital expenditures relating to its transmission business. The Company’s capital expenditure plans are included in Hydro One’s applications to the OEB for transmission and distribution, and are subject to approval by the OEB. See the Annual MD&A under the subheadings “Capital Investments – Future Capital Investments” and “Capital Investments – Major Transmission Capital Investment Projects” for more information on future capital expenditures.

The Company incurs both sustaining capital expenditures and development capital expenditures. Sustaining capital expenditures are those investments required to replace or refurbish our assets and facilities to ensure that the transmission system continues to function as originally designed. Hydro One’s plans to maintain, refurbish or replace existing assets are based upon risk assessments, asset condition assessments and end-of-service life criteria specific to each type of asset. Priorities are assigned to each type of investment based upon the extent of the risks that it mitigates.

Investments to sustain Hydro One’s transmission assets are critical to maintain the safety, reliability and integrity of its existing transmission network. Hydro One’s sustainment capital plan is designed to maintain Hydro One’s transmission reliability performance, as determined by measures such as the average frequency and duration (in minutes) of unplanned interruptions per delivery point. The Company expects that significant investments will be required to sustain its existing infrastructure over the long term.
39


The Company’s development capital expenditure plan is designed to address Ontario’s expected change in the generation profile, accommodate load growth in areas throughout Ontario and support the economic growth in Ontario including industrial and agricultural growth and connection of the remote communities in the northern part of the province. Development capital expenditures include those investments required to develop and build new large-scale projects such as new transmission lines and stations as well as smaller projects such as transmission line or station reinforcements, extensions or additions to connect generation or serve load.

The Company engages with various stakeholders, including its customers and the IESO, as it develops its capital plans. It also engages affected communities and parties who may be impacted by individual projects. The Company also consults with Indigenous communities whose rights may be affected by its projects.

Competitive Conditions

Within our principal market of Ontario, the Company operates and maintains substantially all of the transmission system. Competition for transmission services in Ontario is currently limited. The adoption by the OEB of uniform transmission rates that apply to all transmitters also reduces the financial incentive for customers to seek alternative transmission providers, since each transmitter in Ontario charges the same uniform rate for transmission services. Hydro One competes with other transmitters for the opportunity to build new large-scale transmission facilities in Ontario. The competitive process was amended in 2016 by the proclamation of the Energy Statute Law Amendment Act to allow for the selection of a transmitter outside the existing competitive process. The 2017 Long-Term Energy Plan directed the IESO to develop a transmission procurement process that is clear, cost-effective, efficient and able to respond to changing policy, market and system needs. In October 2020, the IESO, Infrastructure Ontario and the Canada Infrastructure Bank issued a written market sounding to obtain views and insights of various parties regarding potential IESO-led competitive transmission procurement transaction structures, including the role of government, project development activities, allocation of risks and potential financing arrangements. In early 2021, the IESO initiated an engagement to formalize the bulk system planning process. The IESO has noted that the output of the process will inform competitive mechanisms to meet Ontario’s resource adequacy needs.

In November 2023, the IESO launched an engagement initiative with stakeholders on the development of a Transmitter Selection Framework. This initiative supports the Province’s Powering Ontario’s Growth report. The Province expects that the development of a Transmitter Selection Framework will evolve Ontario’s current approach to transmitter selection for transmission projects and provide a predictable process to improve efficiency and foster competition and innovation, while aligning with bulk systems and regional planning. The IESO is expected to report back to the Province by mid-2024. See “The Electricity Industry in Ontario – Regulation of Transmission and Distribution – IESO” for more information.

Hydro One does not compete with other transmitters with respect to investments which are made to sustain or develop its existing transmission infrastructure.

Distribution Business Segment

Overview

Hydro One’s distribution business consists of owning, operating and maintaining Hydro One’s distribution system, which Hydro One, through Hydro One Inc., owns primarily through its wholly-owned subsidiary, Hydro One Networks, the largest local distribution company in Ontario. The Company’s distribution system is also the largest in Ontario. The Company’s distribution business is a rate-regulated business that earns revenues mainly by charging distribution rates that are subject to approval by the OEB. Hydro One’s distribution business also includes the business of its wholly-owned subsidiary, Hydro One Remote Communities, which supplies electricity to customers in remote communities in northern Ontario. The Company’s distribution rates are generally determined using a performance-based model, except for the distribution rates of Hydro One Remote Communities, which are set on a cost-recovery basis and do not include a return on equity.

Hydro One’s distribution business represented approximately 39% of its total assets as at December 31, 2023, and accounted for approximately 46% of its total revenues in 2023, net of purchased power,6 and approximately 71% of its total revenues in 2023 and approximately 48% of its total revenues in 2022, net of purchased power and approximately 73% of its total revenues in 2022. Distribution revenues include distribution rates approved by the OEB and amounts to reimburse Hydro One for the cost of purchasing electricity delivered to its distribution customers. Distribution revenues also include minor ancillary service revenues, such as fees related to the joint use of the Company’s distribution poles by participants in the telecommunications and cable television industries, as well as miscellaneous charges such as charges for late payments.

As at December 31, 2023, Hydro One’s distribution assets were approximately $13 billion.

Business

Hydro One delivers electricity through its distribution network to approximately 1.5 million residential and business customers, most of whom are located in rural areas, as well as 44 local distribution companies (including Hydro One’s own distribution business).

Hydro One’s distribution system includes approximately 125,000 circuit kilometres of primary low-voltage distribution lines and approximately 1,000 distribution and regulating stations. Other distribution assets include poles, transformers, service centres and equipment.

Hydro One’s distribution system services a predominantly rural territory. As a result of the lower
6    Revenues, net of purchased power is a non-GAAP financial measure.
41

population density in the Company’s service territory, the Company’s costs to provide distribution services may be higher than those of distributors who service urban areas. Furthermore, unlike the distribution systems found in urban areas, most of Hydro One’s distribution system was not designed with redundancy, to be interconnected in loops with other distribution lines, with the result that interruptions experienced at any point along a distribution line in Hydro One’s network can cause all customers downstream of the interruption point to lose power. Accordingly, the reliability of Hydro One’s distribution system is lower than that of local distribution companies which service urban territories that typically have redundancy built into their systems.

The Company engages in vegetation management activities to maintain the reliability of Hydro One’s distribution system on a preventive basis and to protect public health and safety. This consists of the trimming or removal of trees to lower the risk of contact with distribution lines, thereby reducing the risk of power outages, and preventing potential injury to the public or employees. The Company’s monitoring systems assist with determining areas of priority and with system restoration. The Company relies on its local line crews for these restoration activities.

Hydro One’s distribution business is involved in the connection of electricity generation, including renewable energy. Hydro One invests in upgrades and modifications to its distribution system to accommodate these sources of generation and ensure the continued reliability of its distribution network. As at December 31, 2023, there were approximately 19,000 small, mid-size and large embedded generators connected to Hydro One’s distribution network, including approximately 16,800 generators with capacities of up to 10 kW. As at December 31, 2023, Hydro One also had approximately 171 generators pending connection.

Hydro One has played a significant role in the installation of smart meters and the migration of distribution customers to time-of-use pricing in Ontario. Smart meters are regarded as an integral means of promoting a culture of conservation and allow customers to change their electricity consumption patterns and reduce their costs. Hydro One has completed all material activities associated with the implementation of smart meters and has transitioned the vast majority of its customers to Time-of-Use pricing. As part of the JRAP, in November 2022, the OEB approved in whole Hydro One Networks’ proposed capital program to modernize the entire smart metering infrastructure as system and assets reach their end of service over the next several years. The new systems will further enable customer interaction and grid operation capabilities. Hydro One is piloting this new system in 2024 with a full implementation expected between 2025 to 2029. See “Business of Hydro One – Transmission Business Segment – Regulation – Recent Transmission Rate Applications – Hydro One Networks” and “Business of Hydro One – Distribution Business Segment – Regulation – Recent Distribution Rate Applications – Hydro One Networks” for more information on Hydro One Networks’ application.

Regulation

Distribution Rates

Distribution rates in Ontario are determined using a performance-based model set out in the OEB’s Renewed Regulatory Framework for Electricity Distributors: A Performance-Based Approach, which is sometimes referred to as the “RRF”. Under the RRF, distributors in Ontario may choose one of three rate-setting methods, depending on their capital requirements: 4th Generation Incentive Rate-Setting (now known as “Price Cap IR”), Custom IR Method, or Annual Incentive Rate-Setting Index.

The RRF contemplates that under the Price Cap IR method, a distributor will apply for the approval of its revenue requirement for an initial base year, reflecting the distributor’s cost of service. The revenue requirement for subsequent years is determined based on a formula that accounts for inflation and certain productivity factors set by the regulator. The revenue requirement in these subsequent years is set on the assumption that the distributor will achieve efficiency or productivity improvements to offset the productivity factor imposed by the regulator.

Under the Custom IR Method, a similar methodology to the Price Cap IR may be used; however, applications are multi-year and are designed to reflect a distributor-specific revenue trend for the application term. For example, a distributor may request incremental capital funding beyond amounts established in the base year revenue requirement.

The scope of applications under the Annual Incentive Rate-Setting Index option is limited to formulaic adjustments to prior year OEB-approved rates. The adjustment provides an increase based on inflation, partially offset by a productivity factor. Distributors under this plan do not have access to mechanisms for additional capital funding beyond the formulaic adjustment.

The RRF allows the distributor to retain all or a portion of the cost savings achieved in excess of the estimate established by the regulator during the period covered by the rate decision, subject to any sharing mechanisms that may be required by the OEB, as indicated in the decision of each rate application. This approach allows the distributor an ability to earn more than its allowed return on equity. The RRF also requires distributors to demonstrate certain performance outcomes, namely: customer focus, operational effectiveness, public policy responsiveness and financial performance. The OEB has stated that customer-focused outcomes and continuous performance improvements by distributors are central to the RRF framework objectives and are considered as part of a distributor rate application.

Performance measures are an important part of the RRF, and the OEB has established a standard performance scorecard for all distributors, which is reported annually. Distributors may also propose additional performance measures for approval by the OEB. Distributors are required to report to the OEB on their performance against the performance measures approved.

The OEB’s review process of the anticipated cost of service for providing distribution services under the
43

RRF follows a process similar to that of a transmission rate application. Once the revenue requirement for distribution services is determined, it is allocated across the distributor’s customer rate classes using a methodology approved by the OEB resulting in the setting of individual rates for distribution services based on each customer rate class. Distribution rates in Ontario are not the same for all distributors and reflect the particular circumstances of each distributor, including its own costs of providing electricity service to its own particular customers. The OEB policy, A New Distribution Rate Design for Residential Electricity Customers, changes the current distribution rate design for residential customers (a combination of a fixed monthly rate and a variable charge) to a fixed monthly charge only. In December 2015, the OEB increased the transition period for certain customer classes of Hydro One Networks to mitigate bill impacts. Implementation of all fixed distribution rates was completed in 2023 for the majority of Hydro One Networks’ residential customers. Changes to rate design will not impact the total revenue to be collected from these customer classes.

Recent Distribution Rate Applications

The Company’s distribution rates, other than the distribution rates of Hydro One Remote Communities, are determined by using a performance-based model.

Hydro One Networks

In August 2021, Hydro One Networks filed a custom joint rate application for 2023-2027 (the “JRAP”) which included a proposed investment plan supporting the transmission and distribution revenue requirements. The JRAP requested the OEB’s approval of distribution revenue requirements of $1,632 million for 2023, $1,711 million for 2024, $1,785 million for 2025, $1,881 million for 2026 and $1,965 million for 2027. In March 2022, Hydro One Networks filed updated evidence reflecting the impacts of updated inflation assumptions on the proposed investment plan as well as updated load forecasts. In October 2022, Hydro One Networks filed a settlement proposal with the OEB, which was further updated in November 2022 to reflect, among other things, the OEB’s cost of capital parameters and inflation factor for 2023. In November 2022, the OEB approved the settlement in whole and issued its final rate order for the 2023-2027 distribution rates approving a revenue requirement of $1,727 million, $1,813 million, $1,886 million, $1,985 million, and $2,071 million for 2023, 2024, 2025, 2026, and 2027, respectively. Notwithstanding that the parties to settlement agreed to reduce Hydro One Networks’ proposed capital and operating expenditures, the approved revenue requirement exceeds Hydro One Networks’ proposed revenue requirement due to increases to the OEB’s cost of capital parameters and inflation factor for 2023. See “Business of Hydro One – Transmission Business Segment – Regulation – Recent Transmission Rate Applications – Hydro One Networks” for more information.

Hydro One Remote Communities

In August 2022, Hydro One Remote Communities filed its Cost of Service rate application for 2023-2027 revenue requirements, including Rural and Remote Rate Protection (“RRRP”), and customer rates for the distribution and generation of electricity in the Hydro One Remote Communities service area. In March
44

2023, the OEB approved the Hydro One Remote Communities’ application, which became effective May 1, 2023, and includes a 3.72% overall rate increase, recovery of variance accounts and additional increases to the RRRP program.

In November 2023, Hydro One Remote Communities filed an application with the OEB for a 4.8% increase to 2023 base rates and escalation of RRRP (Remotes Operating) by the OEB approved inflation factor, effective May 1, 2024. A decision is anticipated in early 2024.

Hydro One Remote Communities’ business is exempt from a number of sections of the Electricity Act which relate to the competitive market. For example, Hydro One Remote Communities continues to apply bundled rates to customers in remote communities. Hydro One Remote Communities’ business is operated on a break-even basis, without a return on equity included in rates. As a result, any net income or loss in the year related to the regulated operations of Hydro One Remote Communities is recorded in a regulatory variance account for disposition in future rate applications.

Conservation and Demand Management

In March 2019, the Province directed the IESO to cancel the 2015-2020 Conservation First Framework and assume accountability for centralized delivery of conservation programs under an interim framework. The interim framework was in effect from April 1, 2019 until August 31, 2022. Under the interim framework, distributors, including Hydro One, were allowed to offer local programs that do not overlap with the IESO’s program offerings. Hydro One continues to deliver CDM programs to those customers for whom CDM project applications were approved.

In September 2020, the Minister of Energy issued a directive to the IESO establishing a $692 million CDM framework for the 2021-2024 period, effective January 1, 2021. The CDM framework focuses on cost-effectively meeting the needs of Ontario’s electricity system, regional and/or local electricity systems, including provincial peak demand reductions, which will be reassessed after the first two years. All programs are centrally delivered by IESO and address system needs identified in bulk, regional or distributor planning processes. Under the current framework, local distribution company participation occurs through the IESO’s competitive process.

In 2023, Hydro One participated in a joint working group with the IESO and other LDCs whereby the group discussed barriers facing LDC participation in delivering CDM programs and identified opportunities for LDCs and the IESO to collaborate in a new CDM framework that is expected to commence in 2025. In August 2023, the working group submitted a Recommendation Report to the Minster of Energy. The new framework is expected to be announced in the latter half of 2024.

Capital Expenditures

Hydro One’s asset sustainment activities are based on an assessment of asset condition. Distribution asset renewals are undertaken when assessments indicate there is a high risk of failure and where further
45

maintenance activities are not appropriate. The Company expects capital expenditures for its distribution business in the near term to focus on new load connections, storm damage, wood pole replacement, and system capability reinforcement. In addition, the Company expects to continue to construct new distribution lines and stations in response to system growth forecasts, continued suburban community development, high load relief requirements and requirements to connect new sources of generation. The Company expects that it will spend in the range of approximately $884 million to $1,093 million per year over the next four years on capital expenditures relating to its distribution business.

Hydro One is continuing to modernize its distribution system through the deployment of smart devices (including remotely controllable switches and breakers as well as faulted circuit indicators) as power system assets are renewed. Hydro One has implemented a Distribution Management System (“DMS”) at its Ontario Grid Control Centre. The DMS has enabled Hydro One to monitor and control distribution components, perform real-time analysis and determine, with greater precision, the location of equipment failures. Additional functionality is planned to allow field staff to view system conditions remotely in real-time. Smart metering data will also be used to deliver operational and asset management benefits such as better notification of outages and their scope, asset loading information and other data. See the Annual MD&A under the subheading “Capital Investments – Future Capital Investments” for more information on future capital expenditures.

Competitive Conditions

Hydro One’s distribution service area is described in its distribution licence issued by the OEB. Only one distributor is permitted to provide distribution services in a service territory, and distributors have exclusive rights to provide service to new customers located within their service territory. As a result, there is very little direct competition for distribution services in Ontario, except near the borders of adjoining service territories, where a distributor may apply to the OEB to claim the right to serve new customers or new loads not currently connected to its distribution grid.

Ontario remains an active environment for local distribution company consolidation, resulting in competition for acquisition or merger opportunities. Potential acquirers may include strategic and financial buyers, in addition to other local distribution companies. Hydro One believes that it is well-positioned to continue to pursue consolidation opportunities within Ontario that are beneficial to all stakeholders. Consolidation continues within Ontario.

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. The telecommunications business is carried out by its wholly-owned subsidiary Acronym Solutions Inc. (formerly, Hydro One Telecom). It also offers comprehensive information and communications technology (ICT) services and solutions (including: internet & network, security, voice & collaboration, cloud and managed IT) that extend beyond Acronym Solutions Inc.’s fibre optic network, in a
46

competitive commercial market.

Acronym Solutions Inc. is not regulated by the OEB. However, Acronym Solutions Inc. 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.

The other segment also includes a deferred tax asset. The deferred tax asset 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. See “Business of Hydro One – Transmission Business Segment – Regulation – Recent Transmission Rate Applications – Hydro One Networks” for information on the deferred tax asset.
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.

The other segment represented approximately 1% of Hydro One’s total assets as at December 31, 2023, and accounted for approximately 1% of its total revenues, net of purchased power,7 in 2023 and 2022 and approximately 1% of its total revenues in 2023 and 2022.

Indigenous Communities

Hydro One believes that building and maintaining respectful, positive and mutually beneficial relationships with Indigenous communities across the province is important to achieving the Company’s corporate objectives. Hydro One has established an Indigenous Relations Policy, demonstrating the Company’s desire to work proactively to build relationships with Indigenous communities based on understanding, respect and mutual trust. Hydro One is committed to working with Indigenous communities in a spirit of cooperation, partnership and shared responsibility. Hydro One’s equity partnerships with the Saugeen Ojibway Nation in respect of the Bruce-to-Milton transmission line and with the Six Nations of the Grand River Development Corporation and the Mississaugas of the Credit First Nation in respect of the Niagara Line demonstrate the Company’s commitment to these principles. In keeping with the Company’s Indigenous Relations Policy, Hydro One’s Indigenous Relations team provides guidance and advice to support the Company in developing and advancing positive relationships. Hydro One also has several programs related to Indigenous communities and their citizens. These include educational and training opportunities which provide opportunities for work terms, Indigenous procurement partnership agreements along with community investments, customer support and outreach. Together, Hydro One Networks and Hydro One Remote Communities serve approximately 100 First Nation communities.

In September 2022, Hydro One announced its new equity partnership model pursuant to which it will
7    Revenues, net of purchased power is a non-GAAP financial measure.
47

offer First Nations a 50% equity stake in all new large-scale capital transmission line projects with a value exceeding $100 million. Hydro One currently has nine transmission lines under development that are subject to the new equity partnership model.

Hydro One supports Indigenous Procurement and has committed to reaching a target of 5% of total sourceable spend with Indigenous businesses by 2026.

The Company’s Indigenous Peoples, Safety & Operations Committee of the Board is responsible for assisting the Board in discharging the Board’s oversight of responsibilities relating to effective occupational health and safety and environmental policies and practices at Hydro One, and its relationship with Indigenous communities.

Outsourced Services

Hydro One has outsourced certain non-core functions, including facilities management services with respect to its stations and other facilities, and certain back-office services such as information technology, payroll, and finance and accounting services. The Company’s back-office services were provided by a third-party service provider under an agreement that expired on December 31, 2021 for finance and accounting services, and the finance and accounting services were insourced back to Hydro One in 2022. For payroll, an extension of services with a third-party service provider expired on December 31, 2023, with such services being insourced back to Hydro One in 2024. The Company’s information technology services are provided by a third-party service provider under an agreement that was extended for two additional one-year terms expiring March 1, 2026. The Company’s facilities management services are provided by a third-party service provider under an agreement that expires on September 15, 2024, with an option for the Company to renew the agreement for an additional term of three years, at the Company’s discretion.

Employees

As at December 31, 2023, Hydro One had approximately 7,000 regular and 2,200 non-regular employees province-wide comprised of a mix of skilled trades, engineering, professional, managerial and executive personnel. The average number of Hydro One employees in 2023 was approximately 9,700, consisting of approximately 6,900 regular employees and approximately 2,800 non-regular employees. 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 access highly trained and appropriately skilled workers on a project-by-project basis. This arrangement provides the Company with more flexibility to address seasonal needs and unanticipated changes to its budgeted work programs. The Company also offers apprenticeship and technical training programs to ensure that future staffing needs will continue to be met.

The collective agreement between Hydro One Inc. and the Society of United Professionals (the “Society”)
48

expired on March 31, 2023. On August 14, 2023, Hydro One Inc. and the Society reached a tentative agreement, and the agreement was ratified on September 11, 2023 and will expire on September 30, 2025.

The collective agreement between Hydro One Inc. and the Power Workers’ Union (the “PWU”) (for the main agreement, covering classifications excluding Customer Service Operations (“CSO”)) expired on March 31, 2023. On June 23, 2023, Hydro One Inc. and the PWU reached a tentative agreement, and the agreement was ratified on August 16, 2023 and will expire September 30, 2025.The collective agreement between Hydro One Inc. and the PWU covering CSO expired on September 30, 2022. On June 23, 2023, Hydro One Inc. and the PWU reached a tentative agreement, and the agreement was ratified on August 21, 2023 and will expire September 30, 2025.

The construction building trade unions have collective agreements with the Electrical Power Systems Construction Association (the “EPSCA”). EPSCA is an employers’ association of which Hydro One is a member. The EPSCA construction collective agreements, which bind Hydro One, were renewed for a five-year period, covering May 1, 2020 to April 30, 2025. The Canadian Union of Skilled Workers (the “CUSW”) is an electrical construction union that represents Hydro One’s direct hire construction electrician and linespersons. The Hydro One Inc. and CUSW collective agreement covers the period from May 1, 2022 to April 30, 2026. See the Annual MD&A under the headings “Hydro One Work Force” and “Collective Agreements” for more information on employees.

Health, Safety and Environmental Management

Hydro One has an integrated Health, Safety and Environment Management System that includes key elements for the successful minimization of risk and continued performance improvements. Health, safety and environmental hazards and risks are identified and assessed, and controls are implemented to mitigate significant risks. The Company has policies in place regarding Health and Safety, Environment, Workplace Violence and Harassment and Public Safety.

Hydro One Networks is a designated “Sustainable Electricity Company” by the Canadian Electricity Association. This designation demonstrates Hydro One’s commitment to responsible environmental, social and economic practices, and to the principles of sustainable development.

Given the nature of the work undertaken by Hydro One employees, health and safety remain one of the Company’s top priorities. Safety is one of Hydro One’s core values. The Company has developed and is continuing to deliver its safety improvement plan consisting of programs and initiatives for incident prevention and to minimize the risk of injury to its employees and the public associated with its facilities and operations.

In 2019, Hydro One’s recordable injury rate reached less than 1 per 200,000 hours worked, a level which has since been maintained year over year. While the Company will continue to monitor and focus on its recordable injury rate, its primary focus is on the elimination of all life altering serious injuries and fatalities as our key Health & Safety performance measure. The Company is also raising the profile of our
49

near miss incident reporting to ensure that the Company learns from and addresses the procedures, training and policies that lead to a safer workplace. All measures are monitored by management and by the Indigenous Peoples, Safety & Operations Committee, a committee of the Board. Management compensation has been tied, in part, to meaningfully improving annual health and safety performance targets. In the event of a fatality and subject to a system investigation, this component of management compensation would not be paid. A program allowing for an effective early and safe return to work has allowed the Company to ensure that, when injuries occur, employees recover and return to the workplace as soon as possible.

Hydro One continues with its “Journey to Zero” safety initiative that began in 2009. This initiative compares Hydro One to other companies to identify performance gaps. Safety perception assessments are completed regularly. The most recent assessment identified opportunities for improvement and, along with other inputs, the Company expects to use this information to develop activities that will make a significant difference to safety in the workplace.

Environmental Regulation

Hydro One is subject to extensive federal, provincial and municipal regulation relating to the protection of the environment that governs, among other things, environmental assessments, discharges to water, air and land, and the generation, storage, transportation, disposal and release of various hazardous substances. Estimated environmental liabilities are reviewed annually or more frequently if significant changes in regulation or other relevant factors occur. Estimated changes are accounted for prospectively.

Permits and Approvals

The Company is required to obtain and maintain specified permits and approvals from federal, provincial and municipal authorities relating to the design, construction and operation of new and upgraded transmission and distribution facilities. Examples include environmental assessment approvals, permits for facilities to be located in parks or other regulated areas, water crossing permits, and approvals to discharge to air and water. Some projects may require environmental approvals from the federal government. Interconnections with neighbouring utilities in other provinces and states also require federal approval and will be subject to federal regulatory review. Hydro One makes every effort during consultation to ensure that Indigenous communities are engaged and that their issues and concerns are reflected in the Company’s environmental assessment process and planning.

In general, larger projects are subject to a comprehensive environmental assessment process, pursuant to the Environmental Assessment Act. The majority of approvals fall under a class environmental assessment process which provides for more streamlined approvals. The scope, timing and cost of environmental assessments are dependent on the scale and type of project, the location (urban versus rural), the environmental sensitivity of affected lands and the significance of potential environmental effects.

50

Regulation of Releases

Federal, provincial and municipal environmental legislation regulates the release of specific substances into the environment through the prohibition of discharges that will or may have an adverse effect on the environment, which can include liquids, gasses and noise. Releases occur in the course of the Company’s normal operations. Accordingly, Hydro One has spill, leak prevention and leak mitigation programs involving the testing, replacement, repair and installation of containment systems including re-gasketting of transformers and sulphur-hexafluoride-filled equipment. In addition, the Company has an emergency response capability which the Company believes is sufficient to minimize the environmental impact of spills and to comply with its legal obligations.

Hazardous Substances

Hydro One manages a number of hazardous substances, such as PCBs, herbicides, and wood preservatives. In addition, some facilities have substances present which are designated for special treatment under occupational health and safety legislation, such as asbestos, lead and mercury. The Company has environmental management programs in place to deal with PCBs, herbicides, asbestos, and other hazardous substances.

Land Assessment and Remediation

Hydro One has a proactive land assessment and remediation program in place to identify and, where necessary, remediate historical contamination that has resulted from past operational practices and uses of certain long-lasting chemicals at the Company’s facilities. These programs involve the systematic identification of contamination at or from these facilities and, where necessary, the development of remediation plans for the Company’s properties and affected adjacent private properties. As at December 31, 2023, future expenditures related to Hydro One’s land assessment and remediation program were estimated at approximately $41 million. These expenditures are expected to be spent over the period ending 2045. Additional acquisitions could add to land assessment and remediation expenditures. The expenditures on this program for 2023 were approximately $2 million. These costs are expected to be recovered in the Company’s transmission and distribution rates and amounts payable to the Company pursuant to the Rural or Remote Electricity Rate Protection Program.

Insurance

Hydro One maintains insurance coverage, including liability, all risk property, boiler and machinery and directors’ and officers’ insurance. The Company also maintains other insurance coverage that is required by law, covering risks such as automobile liability, pesticide liability and aircraft liability. The Company does not have insurance for damage to its transmission and distribution wires, poles or towers located outside transmission and distribution stations, including damage caused by severe weather, other natural disasters or catastrophic events or for environmental remediation costs. The OEB has generally permitted the recovery of costs associated with extreme weather events.
51


Ombudsman

The Electricity Act requires that the Company have an ombudsman to act as a liaison with customers and to establish procedures for the ombudsman to inquire into and report to the Board on matters raised with the ombudsman by or on behalf of customers. These procedures are set out in a written mandate and terms of reference.

The role of the ombudsman is to facilitate resolution of complaints by customers of the Company that remain unresolved after having been processed through the Company’s complaints handling process. The ombudsman is an impartial and independent investigator, who makes recommendations to facilitate the resolution of both individual and systemic issues with a view to achieving a resolution that is fair to both the customer and the Company. The main purposes of the ombudsman are to address procedural and substantive unfairness, handle unresolved complaints, conduct systemic reviews that will lead to improvements in programs and systems, support the Company in holding its employees accountable for carrying out the Company’s directives and their responsibilities, and support the Board in its mandate to govern in a just, fair, and equitable manner. The ombudsman is mandated to work with the OEB to maintain integrated procedures for liaising with the Company and inquiring into matters raised by customers with the ombudsman. The ombudsman is an office of last resort within the Company.

Dividend Policy

The Board has established a dividend policy pursuant to which Hydro One Limited expects to pay an annualised dividend amount on its common shares, based on a target payout ratio of 70% to 80% of net income. The amount and timing of any dividends payable by Hydro One Limited will be at the discretion of the Board and will be established on the basis of Hydro One’s results of operations, maintenance of its deemed regulatory capital structure, financial condition, cash requirements, the satisfaction of solvency tests imposed by corporate laws for the declaration and payment of dividends and other factors that the Board may consider relevant.

The preferred shares of Hydro One Limited are entitled to a preference over the common shares with respect to the payment of dividends. Other than the foregoing, there is currently no restriction that would
53

prevent Hydro One Limited from paying dividends at current levels.

For more information on dividends, see the notes to the audited consolidated financial statements of Hydro One Limited as at and for the years ended December 31, 2023 and 2022.

Dividend Reinvestment Plan

In February 2016, the Board approved the creation of a dividend reinvestment plan (the “Dividend Reinvestment Plan”) which is currently in place. The Dividend Reinvestment Plan enables eligible shareholders to have their regular quarterly cash dividends automatically reinvested in additional Hydro One common shares acquired on the open market.

DESCRIPTION OF CAPITAL STRUCTURE

General Description of Capital Structure

The following description may not be complete and is subject to, and qualified in its entirety by reference to, the terms and provisions of Hydro One Limited’s articles, as they may be amended from time to time.
Hydro One Limited’s authorized share capital consists of an unlimited number of common shares and an unlimited number of preferred shares, issuable in series. As at December 31, 2023, there were 599,077,067 common shares, no Series 1 preferred shares and no Series 2 preferred shares issued and outstanding.

Common Shares

Holders of common shares are entitled to receive notice of and to attend all meetings of shareholders, except meetings at which only the holders of another class or series of shares are entitled to vote separately as a class or series, and holders of common shares are entitled to one vote per share at all such meetings of shareholders. Hydro One Limited’s common shares are not redeemable or retractable. Subject to the rights, privileges, restrictions and conditions attaching to any other class or series of shares, including the Series 1 preferred shares and Series 2 preferred shares, holders of common shares are entitled to receive dividends if, as, and when declared by the Board. Subject to the rights, privileges, restrictions and conditions attaching to any other class or series of shares, including the Series 1 preferred shares and Series 2 preferred shares, holders of common shares are also entitled to receive the remaining assets of Hydro One Limited upon its liquidation, dissolution or winding-up or other distribution of Hydro One Limited’s assets for the purposes of winding-up its affairs. See “Dividends – Dividend Policy” for a description of Hydro One Limited’s dividend policy.

The Voting Securities of Hydro One Limited, which include the common shares, are subject to the Share Ownership Restrictions under the Electricity Act and certain other provisions contained in the articles of Hydro One Limited related to the enforcement of those share ownership restrictions. The Share Ownership Restrictions provide that no person or company (or combination of persons or companies
54

acting jointly or in concert), other than the Province or an underwriter who holds Voting Securities solely for the purposes of distributing them to purchasers who comply with the Share Ownership Restrictions, may beneficially own or exercise control or direction over more than 10% of any class or series of Voting Securities of Hydro One Limited.

Preferred Shares

Hydro One Limited may from time to time issue preferred shares in one or more series. Prior to issuing shares in a series, the Board 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.

Subject to the OBCA, holders of Hydro One Limited’s preferred shares or a series thereof are not entitled to receive notice of, to attend or to vote at any meeting of the shareholders of Hydro One Limited 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 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 Limited. The preferred shares are entitled to a preference over the common shares and any other shares ranking junior to the preferred shares with respect to payment of dividends and the distribution of assets and return of capital in the event of the liquidation, dissolution or winding up of Hydro One Limited.

Series 1 Preferred Shares and Series 2 Preferred Shares

For the period commencing from October 31, 2015, and ending on and including November 19, 2020, the holders of Series 1 preferred shares were entitled to receive fixed cumulative preferential dividends of $1.0625 per share per year, if and when declared by the Board, payable quarterly on the 20th day of November, February, May and August in each year. The dividend rate initially reset on November 20, 2020 and resets every five years thereafter at a rate equal to the sum of the then five-year Government of Canada bond yield and 3.53%. The Series 1 preferred shares became redeemable by Hydro One Limited on November 20, 2020 at a redemption price equal to $25.00 for each Series 1 preferred share redeemed, plus any accrued or unpaid dividends. The holders of Series 1 preferred shares had the right, at their option, on November 20, 2020 and every fifth year thereafter, to convert all or any of their Series 1 preferred shares into Series 2 preferred shares on a one-for-one basis, subject to certain restrictions on conversion. On November 20, 2020, Hydro One Limited completed the redemption of all of the outstanding Series 1 preferred shares in accordance with their terms.

The holders of Series 2 preferred shares will be entitled to receive quarterly floating rate cumulative dividends, if and when declared by the Board, at a rate equal to the sum of the then three-month Government of Canada treasury bill rate and 3.53% as reset quarterly. The Series 2 preferred shares will be redeemable by Hydro One Limited at a redemption price equal to $25.00 for each Series 2 preferred share redeemed if redeemed on November 20, 2025, or on November 20 every fifth year thereafter or $25.50 for each Series 2 preferred share redeemed if redeemed on any other date after November 20,
55

2020, in each case plus any accrued or unpaid dividends. The holders of Series 2 preferred shares will have the right, at their option, on November 20, 2025, and on November 20 every fifth year thereafter, to convert all or any of their Series 2 preferred shares into Series 1 preferred shares on a one-for-one basis, subject to certain restrictions on conversion.

In the event of the liquidation, dissolution or winding-up of Hydro One Limited, or any other distribution of assets of Hydro One Limited for the purpose of winding-up its affairs, the holders of Series 1 preferred shares and Series 2 preferred shares will be entitled to receive $25.00 for each Series 1 preferred share and each Series 2 preferred share held by them, plus any unpaid dividends, before any amounts are paid or any assets of Hydro One Limited are distributed to holders of common shares and any shares ranking junior to the Series 1 preferred shares and Series 2 preferred shares. After payment of those amounts, the holders of Series 1 preferred shares and Series 2 preferred shares will not be entitled to share in any further distribution of the property or assets of Hydro One Limited.

Except as required by the OBCA, neither the holders of Series 1 preferred shares nor the holders of Series 2 preferred shares shall be entitled to receive notice of, or to attend meetings of shareholders of Hydro One Limited and shall not be entitled to vote at any such meeting, unless Hydro One Limited fails for eight quarters, whether or not consecutive, to pay in full the dividends payable on the Series 1 preferred shares or Series 2 preferred shares, as applicable, whereupon the holders of Series 1 preferred shares and Series 2 preferred shares, as applicable, shall become entitled to receive notice of and attend all meetings of shareholders, except class meetings of any other class of shares, and shall have one vote for each Series 1 preferred share or Series 2 preferred share held at such meetings, as applicable.

CREDIT RATINGS

As of December 31, 2023, Hydro One Limited’s long-term debt ratings were as follows:

Rating Agency
Long-term Debt
Rating
DBRS Limited (“DBRS”)A
S&P Global Ratings (“S&P”)BBB+

Hydro One Limited has also been assigned an issuer credit rating of A with a stable trend from DBRS and A- with a positive outlook from S&P.8

Credit ratings are intended to provide investors with an independent measure of the credit quality of an issue of securities and are indicators of the likelihood of payment and of the capacity and willingness of a company to meet its financial commitment on an obligation in accordance with the terms of the
8 In August 2023, S&P revised its outlook on Hydro One Limited to positive from stable and affirmed the Company’s existing issuer and issue-level ratings.

obligation.

The rating agencies rate long-term debt instruments by rating categories ranging from a high of AAA to a low of D. Long-term debt instruments which are rated in the A category by DBRS are in the third highest category and are considered to be of a good credit quality, with substantial capacity for the payment of financial obligations. Entities in the A category may be vulnerable to future events, but qualifying negative factors are considered manageable. The assignment of a “positive”, “stable” or “negative” trend provides guidance in respect of DBRS’ opinion regarding the trend for the rating. The rating trend indicates the direction in which DBRS considers the rating may move if present circumstances continue, or in certain cases, unless challenges are addressed by the issuer. Long-term debt instruments which are rated in the BBB category by S&P are in the fourth highest category and exhibit adequate protection parameters although adverse economic conditions or changing circumstances are more likely to weaken the obligor’s capacity to meet its financial commitments on the obligation. S&P may modify the ratings from AA to CCC using a plus (+) or minus (-) sign to show relative standing within the major rating categories. The addition of a rating outlook such as “stable”, “positive”, “negative” or “developing” assesses the potential direction of a long-term credit rating over the intermediate term (typically six months to two years). An outlook is not necessarily a precursor of a ratings change.

The ratings mentioned above are not a recommendation to purchase, sell or hold Hydro One Limited’s debt securities and do not comment as to market price or suitability for a particular investor. There can be no assurance that the ratings will remain in effect for any given period of time or that the ratings will not be revised or withdrawn entirely by any or all of DBRS and S&P at any time in the future if, in their judgment, circumstances so warrant.

Hydro One has made, and anticipates making, payments to each of DBRS and S&P pursuant to the ratings agency services agreements entered into with such credit rating organizations with respect to the ratings assigned to the long-term debt (including the 1.41% Notes) of Hydro One Limited and long-term debt and commercial paper of Hydro One Inc. There have been no other services provided by DBRS or S&P to Hydro One within the last two years.

Various ratings organizations review the Company’s debt ratings from time to time. These ratings 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.

•the Registration Rights Agreement on November 5, 2015 to provide the Province with the right to require Hydro One Limited to facilitate future secondary offerings of common shares or preferred shares owned or controlled by the Province on November 5, 2015; and

•the Letter Agreement on July 11, 2018 for the purpose of the orderly replacement of the Board and the retirement of the then CEO.

The Governance Agreement and the Registration Rights Agreement were entered into in connection with the completion of the initial public offering of Hydro One Limited in November 2015 and the Letter Agreement was entered into in connection with the retirement of the CEO and replacement of the Board in July 2018. The material terms of each are summarized below. Copies of the Governance Agreement, the Registration Rights Agreement and the Letter Agreement have been filed on SEDAR+ and are available under Hydro One Limited’s profile at www.sedarplus.com. The discussion in this annual information form concerning the Governance Agreement, the Registration Rights Agreement and the Letter Agreement, as the case may be, is not complete, and is qualified in its entirety to the text of the Governance Agreement, the Registration Rights Agreement and the Letter Agreement, each of which
70

should be referred to. Not all of the terms of the Governance Agreement, the Registration Rights Agreement and the Letter Agreement are described in this annual information form.

Governance Agreement

Governance Matters

The Governance Agreement specifically addresses the following governance matters:

•The governance principles under which Hydro One Limited and its subsidiaries will be managed and operated.

•The nomination of directors, which includes: (i) the requirement for a fully independent board of directors (other than the CEO), and (ii) the maximum number of directors that may be nominated by the Province.

•The election and replacement of directors.

•Approvals requiring a special resolution of the directors.

Governance Principles

The Governance Agreement provides that the business and affairs of Hydro One Limited will be managed and operated in accordance with certain governance principles.

The governance principles provide that:

•Hydro One Limited will maintain corporate governance policies, procedures and practices consistent with the best practices of leading Canadian publicly listed companies, having regard to Hydro One Limited’s ownership structure and the Governance Agreement.

•The board of directors of Hydro One Limited is responsible for the management of the business and affairs of Hydro One Limited.

•With respect to its ownership interest in Hydro One Limited, the Province will engage in the business and affairs of Hydro One Limited as an investor and not a manager, and the Province intends to achieve its policy objectives through legislation and regulation, as it would with respect to any other utility operating in Ontario.

Nomination of Directors

The Governance Agreement establishes qualification standards for director nominees, provides for the
71

number of directors that may be nominated and establishes a process for confirming nominees. The Governance Agreement recognizes that the Board is to be a fully independent board (independent of both Hydro One and the Province), except the CEO, as described under the subheading “Independence” below.

Director Qualification Standards

Under the Governance Agreement, the Province and the Governance & Regulatory Committee (formerly the Nominating, Corporate Governance, Public Policy & Regulatory Committee and then Governance Committee) have agreed to nominate as directors qualified individuals of high quality and integrity who have the experience, expertise and leadership appropriate to manage a business of the complexity, size and scale of the business of Hydro One Limited, on a basis consistent with the highest standards for directors of Canada’s leading public companies.

In addition, a majority of the directors must be resident Canadians (as defined in the OBCA).

Independence

Each director nominee must, among other things:

•be independent of Hydro One Limited (other than the CEO) within the meaning of Ontario securities laws governing the disclosure of corporate governance practices;

•be independent of the Province (other than the CEO). A director will be independent of the Province if he or she would be independent of Hydro One Limited within the meaning of Ontario securities laws governing the disclosure of corporate governance practices if the Province and each Specified Provincial Entity were treated as Hydro One Limited’s parent under that definition. In addition, he or she may not be an employee or official of the Province or any Specified Provincial Entity, either: (i) currently or (ii) within the last three years; and

•meet the requirements of applicable securities and other laws and any exchange on which the voting securities are listed.

A “Specified Provincial Entity” means (1)(a) the Ontario Financing Authority, (b) the IESO, (c) Ontario Power Generation Inc., (d) the Electrical Safety Authority, (e) Ontario Electricity Financial Corporation, (f) Infrastructure Ontario, or (g) a subsidiary of, or a person controlled by, any organization listed in (a) to (f); and (2) the OEB.

Number of Directors

Under the articles of Hydro One Limited and pursuant to the terms of the Governance Agreement, the Board will consist of no fewer than 10 and no more than 15 directors.

72

Board Nominees

The nominees to be proposed for election to the Board by Hydro One Limited at annual meetings of shareholders will be determined as follows:

•The CEO will be nominated.

•The Province will be entitled to nominate that number of nominees equal to 40% of the number of directors to be elected (rounded to the nearest whole number), subject to certain exceptions.

•The Governance Committee will nominate the remaining directors.

Board Nomination Process

Under the Governance Agreement, the Province and representatives of the Governance & Regulatory Committee are to meet after each annual meeting of shareholders to discuss expected upcoming departures from the Board (whether due to resignation, retirement or otherwise) and the impact such departures will have on the Board, having regard to continued compliance with the Governance Agreement and the ability of the Board to satisfy the Board’s skills matrix, diversity policy and other governance standards. Under the Governance Agreement, at this meeting the Governance & Regulatory Committee is to make recommendations to the Province respecting potential candidates for director, including potential candidates for nomination by the Province. The Province has no obligation to nominate any of the individuals recommended as one of its director nominees.

Not later than 60 days prior to the date by which proxy solicitation materials must be mailed for Hydro One’s annual meeting of shareholders, each of the Province and the Governance & Regulatory Committee will notify the other of its proposed director nominees. If a proposed nominee is not already a director of Hydro One, or is then a director but whose circumstances have materially changed in a way that would affect whether she or he would continue to meet the director qualification standards under the Governance Agreement, then the Province or the committee, as the case may be, will have 10 business days to confirm that nominee or reject that nominee on the basis that the nominee does not meet those director qualification standards.

If a director nominee of the Province or the Governance & Regulatory Committee is rejected, then the Province or the committee will be entitled to nominate additional candidates until a nominee is confirmed by the other. If no replacement nominee is confirmed for a director who was expected to depart from the board and that director does not resign, that director shall be re-nominated. The Province and the committee will use commercially reasonable efforts to confirm director nominees prior to the date by which proxy solicitation materials must be mailed for the annual meeting of shareholders.

73

Election and Replacement of Directors

The Governance Agreement provides for how:

•the Province will vote with respect to director nominees, including its nominees and those of the Governance & Regulatory Committee,

•the Province may vote at contested elections,

•the Province may seek to replace the Board by withholding votes or voting for removal, and

•Board vacancies will be filled.

Voting on Director Elections

At any meeting of shareholders to elect directors, the Province is required to vote in favour of the nominees selected by the Province and the Governance & Regulatory Committee in accordance with the board nomination process set out in the Governance Agreement, except in the case of contested director elections or where the Province seeks to replace the Board in accordance with the Governance Agreement.

Contested Elections

At any meeting of shareholders to elect directors of Hydro One Limited at which there are more nominees for directors than there are directors to be elected, the Province may vote its Voting Securities in its sole discretion (including to vote in favour of other candidates instead of the Province’s nominees), except that the Province will vote in favour of the election of the CEO as a director.

Right to Withhold Votes

The Province is required under the Governance Agreement to vote in favour of all director nominees of Hydro One Limited, subject to the Province’s overriding right to withhold from voting in favour of all director nominees and its 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. Depending on the number of withheld votes a director nominee receives at a meeting of shareholders at which directors are to be elected, that director nominee may be required to tender his or her resignation to the Board in accordance with Hydro One Limited’s majority voting policy.

Province’s Right to Replace the Board

The Province may at any time notify Hydro One Limited that it intends to request that Hydro One Limited hold a meeting of shareholders for the purposes removing all of the directors in office, including those
74

nominated by the Province, with the exception of the CEO and, at the sole discretion of the Province, the Chair (a “Removal Notice”). If the Province gives Hydro One a Removal Notice, then the Chair shall coordinate the establishment of an ad hoc nominating committee comprising one representative of each of the five largest beneficial owners of Voting Securities known to the Company (or if at least three such owners are not willing to provide a representative, then the individuals the Province proposes to nominate as replacement directors). The Province and the ad hoc nominating committee will identify and confirm replacement directors to be nominated at the shareholders’ meeting in accordance with the process set out in the Governance Agreement. Each replacement director nominee must meet the same qualification and independence standards under the Governance Agreement as for any director nominee. Hydro One Limited will call the shareholders’ meeting once the replacement director nominees are confirmed pursuant to this process, and will hold the shareholders’ meeting within 60 days of this confirmation. At the shareholders’ meeting, the Province will vote in favour of removing the current directors with the exception of the CEO and, at the Province’s discretion, the Chair, and will vote in favour of the new independent director nominees.

Board Approvals Requiring a Special Resolution of the Directors

The Governance Agreement provides that certain actions require approval by a resolution of the Board passed by at least two-thirds of the votes cast at a meeting of the directors, or consented to in writing by all of the directors (a “Special Board Resolution”). Matters requiring approval by a Special Board Resolution include:

•the appointment and annual confirmation of the Chair,

•the appointment and annual confirmation of the CEO, and

•changes to certain specified governance standards specified in the Governance Agreement to be “Hydro One’s governance standards”.

The governance standards subject to this special approval requirement include the Board’s skills matrix, the Ombudsman’s Mandate, the Diversity Policy and the Majority Voting Policy, the Corporate Governance Guidelines, the mandates of the Board and its committees, position descriptions for the CEO, the Chair, the directors and committee chairs, and the Stakeholder Engagement Policy.

Other Matters

In addition to the governance matters noted above, the Governance Agreement also addresses the following matters:

•Restrictions on the right of the Province to initiate fundamental changes,

•Pre-emptive rights provided to the Province with respect to future issuances of Voting Securities
75

by Hydro One Limited, and

•Acquisition limits with respect to the Province’s acquisition of outstanding Voting Securities.

Restrictions on Province’s Right to Initiate Fundamental Changes

The Province has agreed not to initiate a fundamental change to Hydro One Limited (as defined in Part XIV of the OBCA), including not to initiate any arrangement or amalgamation involving Hydro One Limited or any amendment to the articles of Hydro One Limited. The Province may, however, vote its Voting Securities as it sees fit in the event any fundamental change is initiated by Hydro One Limited or another shareholder of Hydro One Limited.

Pre-emptive Rights

Hydro One Limited has granted to the Province a pre-emptive right to acquire additional Voting Securities as part of future offerings by Hydro One Limited of Voting Securities. If Hydro One Limited proposes to issue Voting Securities in the future, whether pursuant to a public offering or a private placement, Hydro One Limited must notify the Province of the proposal and provide information in accordance with the provisions of the Governance Agreement at least 30 days in advance and must offer the Province the right to purchase up to 45% of the Voting Securities being offered. Any Voting Securities not purchased by the Province pursuant to the offer may be purchased by any other person pursuant to the proposed offering.

The pre-emptive right also applies with respect to any proposed issuance by Hydro One Limited of securities convertible into or exchangeable for Voting Securities except securities convertible into or exchangeable for Voting Securities: (i) pursuant to certain employee or director compensation plans; (ii) pursuant to any dividend re-investment arrangement of the Company that is consistent with dividend reinvestment arrangements of other publicly traded utilities in Canada (including as to discount rates) and that does not include a cash purchase option; (iii) pursuant to a rights offering that is open to all shareholders of Hydro One Limited; or (iv) pursuant to any business combination, take-over bid, arrangement, asset purchase transaction or other acquisition of assets or securities of a third-party.

45% Acquisition Limit

The Province has agreed in the Governance Agreement, subject to certain exceptions, not to acquire previously issued Voting Securities if, after that acquisition, the Province would own more than 45% of any class or series of Voting Securities. This restriction does not limit the Province from acquiring Voting Securities on an issuance by Hydro One Limited, including pursuant to the exercise by the Province of its pre-emptive right. See “Agreements with Principal Shareholder – Governance Agreement – Other Matters – Pre-emptive Rights” above.

76

Registration Rights Agreement

Demand Registration

Pursuant to the Registration Rights Agreement, Hydro One Limited has granted the Province certain demand registration rights providing that, from time to time while the Province is a “control person” of Hydro One Limited within the meaning of applicable Canadian securities laws, the Province can require Hydro One Limited to file, at the expense of the Province (except for internal expenses of Hydro One Limited or other expenses that Hydro One Limited would have incurred in the absence of such a request), and subject to certain exceptions, one or more prospectuses and take other procedural steps as may be reasonably necessary to facilitate a secondary offering in Canada of all or any portion of the common shares or preferred shares (“Shares”) held by the Province.

“Piggy-Back” Registration

If Hydro One Limited proposes to undertake a Canadian public offering by prospectus, the Province is entitled, while it is a “control person” of Hydro One Limited within the meaning of applicable Canadian securities laws, to include Shares owned by it as part of that offering, provided that the underwriters may reduce the number of Shares proposed to be sold if in their reasonable judgment all of the Shares proposed to be offered by Hydro One Limited and the Province may not be sold in an orderly manner within a price range reasonably acceptable to Hydro One Limited. In that case, the Shares to be sold will be allocated pro rata between Hydro One Limited and the Province based on their relative proportionate number of Shares requested to be included in the offering. Hydro One Limited and the Province will share the expenses of the offering (except for internal expenses of Hydro One Limited) in proportion to the gross proceeds they each receive from the offering.

Private Placements

Hydro One Limited has also agreed to use commercially reasonable efforts to assist, at the Province’s expense, the Province in any sale by it of Shares of Hydro One Limited pursuant to an exemption from the prospectus requirements, in the preparation of an offering memorandum and other documentation and by facilitating due diligence by the prospective buyer.

Customary Agreements

Hydro One Limited and the Province have also agreed to enter into customary agreements, including “lock-up” agreements, on customary market terms in connection with such transactions. Hydro One Limited also agreed to certain indemnification and contribution covenants in favour of the Province and any underwriters involved in such transactions.

77

Letter Agreement

The Letter Agreement set out the agreement between Hydro One Limited and the Province with respect to the orderly replacement of the Board and the retirement of the then CEO, effective July 11, 2018.

In addition to the above, other key highlights of the Letter Agreement include:

•Hydro One Limited agreed to consult with the Province in respect of future matters of executive compensation; and

•The Province ratified and reaffirmed its obligations under the Governance Agreement and agreed that except as set out in the Letter Agreement, the Letter Agreement did not amend or modify the Governance Agreement and the Governance Agreement remained in full force and effect.

INTEREST OF MANAGEMENT AND OTHERS IN MATERIAL TRANSACTIONS

Other than as noted below and elsewhere in this annual information form, there are no material interests, direct or indirect, of any director or executive officer of the Company, any shareholder that beneficially owns, or controls or directs (directly or indirectly), more than 10% of any class or series of Hydro One Limited’s outstanding voting securities, or any associate or affiliate of any of the foregoing persons, in any transaction within the three most recently completed financial years or during the current financial year, up to the date of this annual information form, that has materially affected or is reasonably expected to materially affect the Company.

Relationships with the Province and Other Parties

Overview

The Province is Hydro One Limited’s principal shareholder. The OEB is the principal regulator of Ontario’s electricity industry. The Province appoints the board members of the OEB and fills any vacancies on the OEB. The OEB is obligated to implement approved directives of the Province concerning general policy and objectives to be pursued by the OEB and other directives aimed at addressing existing or potential abuses of market power by industry participants. The IESO, among other matters, directs the operation of the Ontario power system by balancing supply and demand of electricity and directing electricity flow and assumed the responsibility for forecasting supply and demand of electricity over the medium and long term to meet the needs of the province. The board of directors of the IESO, other than its CEO, is appointed by the Province in accordance with the regulations in effect from time to time under the Electricity Act.

In connection with the initial public offering of Hydro One Limited, the Company entered into the Governance Agreement and the Registration Rights Agreement with the Province. Following the election of a new government in Ontario in June 2018, the Company and the Province entered into the Letter
78

Agreement. See “Agreements with Principal Shareholder”.

Transfer Orders

The transfer orders pursuant to which Hydro One Inc. acquired Ontario Hydro’s electricity transmission, distribution and energy services businesses as of April 1, 1999, did not transfer certain assets, rights, liabilities or obligations where the transfer would constitute a breach of the terms of any such asset, right, liability or obligation or a breach of any law or order (the “trust assets”). The transfer orders did not transfer title to assets located on Reserves, which assets are held by OEFC. See the Annual MD&A under the subheading “Risk Management and Risk Factors – Risks Relating to Hydro One’s Business – Risk from Transfer of Assets Located on Reserves” for more information.

Until it has obtained all consents necessary to complete the transfer of title to these assets to Hydro One, Hydro One is obligated under the transfer orders to manage both the trust assets and the assets otherwise retained by OEFC that relate to Hydro One’s businesses. Hydro One has entered into an agreement with OEFC under which it is obligated, in managing these assets, to take instructions from OEFC if Hydro One’s actions could have a material adverse effect on OEFC. OEFC has retained the right to take control of and manage the assets, although it must notify and consult with Hydro One before doing so and must exercise its powers relating to the assets in a manner that will facilitate the operation of Hydro One’s businesses. The consent of OEFC is also required prior to any disposition of these assets.

The Province also transferred officers, employees, assets, liabilities, rights and obligations of Ontario Hydro in a similar manner to its other successor transferees. These transfer orders include a dispute resolution mechanism to resolve any disagreement among the various transferees with respect to the transfer of specific assets, liabilities, rights or obligations.

The transfer orders do not contain any representations or warranties from the Province or OEFC with respect to the transferred officers, employees, assets, liabilities, rights and obligations. Furthermore, under the Electricity Act, OEFC was released from liability in respect of all assets and liabilities transferred by the transfer orders, except for liability under Hydro One’s indemnity from OEFC. The parties, with the consent of the Minister of Finance, agreed to terminate such indemnity effective October 31, 2015. By the terms of the transfer orders, each transferee indemnifies OEFC with respect to any assets and liabilities related to that transferee’s business not effectively transferred, and is obligated to take all reasonable measures to complete the transfers where the transfers were not effective.

Hydro One has indemnified OEFC in respect of the damages, losses, obligations, liabilities, claims, encumbrances, penalties, interest, taxes, deficiencies, costs and expenses arising from matters relating to the Company’s business and any failure by Hydro One to comply with its obligations to OEFC under agreements dated as of April 1, 1999. These obligations include obligations to employ the employees transferred to Hydro One under the transfer orders, make and remit employee source deductions (including tax withholding amounts, and employer contributions), manage the real and personal properties which OEFC continues to hold in trust or otherwise and take any necessary action to transfer all of these
79

properties to the Company, to pay realty taxes and other costs, provide access to books and records and to assume other responsibilities in respect of the assets held by OEFC in trust for the Company.

MATERIAL CONTRACTS

The following are the only material contracts, other than those contracts entered into in the ordinary course of business, which Hydro One Limited has entered into since the beginning of the last financial year, or entered into prior to such date but which contract is still in effect:

(a)the Governance Agreement, described under “Agreements with Principal Shareholder”;

(b)the Registration Rights Agreement, described under “Agreements with Principal Shareholder”;

(c)the Letter Agreement, described under “Agreements with Principal Shareholder”;

(d)the agency agreement (the “Agency Agreement”) dated September 24, 2020 between Hydro One Limited and RBC Dominion Securities Inc., BMO Nesbitt Burns Inc., CIBC World Markets Inc., National Bank Financial Inc., Scotia Capital Inc., TD Securities Inc., Casgrain & Company Limited, Desjardins Securities Inc., Laurentian Bank Securities Inc. and Mizuho Securities Canada Inc. (collectively, the “Agents”), relating to the offering by Hydro One Limited of the 1.41% Notes. The Agency Agreement provides for the appointment of the Agents as the exclusive agents to, on a best efforts basis, solicit offers to purchase the 1.41% Notes and to offer the 1.41% for sale in all of the provinces and territories of Canada. The Agency Agreement provides that Hydro One Limited will indemnify each of the Agents and their respective directors, officers, employees, agents and affiliates against certain liabilities, including non-compliance with applicable Canadian securities legislation;

(e)the indenture (the “HOL Indenture”) dated as of October 15, 2020 between Hydro One Limited and Computershare Trust Company of Canada, providing for the creation and issuance of, from time to time, of debt securities, to be issued in one or more series; and

(f)a first supplemental indenture dated as of October 15, 2020 relating to the issuance of the 1.41% Notes in an unlimited aggregate principal amount, of which $425,000,000 was drawn down on October 15, 2020, pursuant to the HOL Indenture.

Copies of the foregoing material agreements have been filed with the Canadian securities regulatory authorities and are available on SEDAR+ at www.sedarplus.com. As of the date of this annual information form, HOHL has not issued any debt securities pursuant to the trust indenture dated as of June 8, 2018 between HOHL, as issuer, HOL, as guarantor, Computershare Company, N.A., as United States trustee, and Computershare Trust Company of Canada, as Canadian trustee (the “HOHL Indenture”). Accordingly, the HOHL Indenture is not considered a material agreement. If and when such debt securities are issued pursuant to the HOHL Indenture, such agreement may be considered a material
80

agreement.

LEGAL PROCEEDINGS AND REGULATORY ACTIONS

The Company is from time to time involved in legal proceedings of a nature considered normal to its business. Except as disclosed below, Hydro One believes that none of the litigation in which it is currently involved, or has been involved since the beginning of the most recently completed financial year, individually or in the aggregate, is material to its consolidated financial condition or results of operations. The Company is not subject to any material regulatory actions.

In connection with the reorganization of Ontario Hydro, Hydro One Inc. and certain of its subsidiaries succeeded Ontario Hydro as party to various pending legal proceedings relating to the businesses, assets, real estate and employees transferred to them. Hydro One Inc. and certain of its subsidiaries also assumed responsibility for future claims relating to the businesses, assets, real estate and employees acquired by them respectively and arising out of events occurring prior to, as well as after, April 1, 1999. In addition to claims assumed by the Company, it is, from time to time, named as a defendant in legal actions arising in the normal course of business. There are currently no actions that are outstanding which are expected to have a material adverse effect on the Company.

See the Annual MD&A under the heading “Risk Management and Risk Factors – Risks Relating to Hydro One’s Business – Litigation Risks” for more information.

S-1

conduct of the annual audit.
