What Hydro One does
Hydro One is Ontario's largest electricity transmission and distribution utility, operating under a regulated monopoly framework overseen by the Ontario Energy Board. The company was established in 1998 following Ontario's electricity market restructuring and serves approximately 1.5 million end-use customers across the province through high-voltage transmission lines, distribution substations, and local distribution infrastructure. Hydro One generated approximately $9 billion CAD in annual revenue in 2025 and holds $39.7 billion in total assets, with a market capitalization near C$35.35 billion. Revenue is earned primarily through OEB-approved regulated rates for two core streams: transmission services (high-voltage power transport across Ontario) and distribution services (last-mile delivery to residential, commercial, industrial, and remote community customers). Customer pricing is structured around three OEB-regulated plans — Time-of-Use, Tiered, and the newly introduced Ultra-Low Overnight (effective November 2025) — with an Ontario Electricity Rebate applied automatically. The customer base spans residential households, commercial/industrial accounts, mining operators (e.g., the Canada Nickel Crawford Project), and approximately 30 remote First Nations communities served by subsidiary Hydro One Remote Communities Inc.
The company's technology stack is anchored by extensive physical grid assets supplemented by smart metering infrastructure (Advanced Metering Infrastructure) and digital customer-facing products including the myAccount portal, Hydro One Mobile App (iOS/Android), and the Storm Centre real-time outage map. Recent technical investments include AI-enabled analytics (via Bidgely) for AMI data analysis, EV load forecasting, and infrastructure prioritization. The company operates a First Nation Equity Partnership Model offering Indigenous communities up to 50% equity stakes in transmission line components of major projects — a distinctive social-license approach embedded into 12 transmission lines by year-end 2025. Capital structure features a Sustainable Financing Framework with green bond issuances totaling $1.6 billion CAD in November 2025 and $1.0 billion USD in May 2026.
Hydro One's business model is a regulated rate-of-return utility: customer acquisition occurs through provincial service-territory allocation rather than competitive sales, revenue is determined by OEB-approved rates, and growth is driven by OEB-approved capital projects, rate-base expansion, and emerging revenue streams from EV infrastructure (Ivy Charging Network joint venture with Ontario Power Generation, EVC Rate). The company is in active leadership transition, with Megan Telford appointed President and CEO effective June 9, 2026, succeeding David Lebeter. The capital plan is substantial: filed and designated projects include the $1.8 billion Northeast Power Line, $1.2 billion Longwood to Lakeshore, a 500-kV Sudbury-to-Barrie corridor, and 230-kV Red Lake and Bowmanville-to-GTA expansions, positioning the company as the backbone for Ontario's electrification, mining growth (including the Ring of Fire), and data center demand.

Hydro One competitors and assessment
Company assessmentBroad incumbents
- National Grid plc: Large UK/US regulated electricity and gas T&D utility. Comparable as a regulated transmission and distribution operator with scale, monopoly franchise structure, and a heavy regulated capex program.
- Avista Corporation: US regulated electric and gas utility serving the Pacific Northwest. Comparable as a regulated T&D utility using the same Bidgely AMI analytics platform as Hydro One and operating under a similar rate-case regulatory model.
- Ontario Power Generation (OPG): Province of Ontario-owned electricity generator and partner of Hydro One in the Ivy Charging Network JV. Overlaps in Ontario energy infrastructure but OPG's primary business is generation rather than T&D.
Direct peers
- Emera Incorporated: Canadian regulated utility holding company with electric T&D and generation assets across Canada, the US, and the Caribbean. Comparable as a regulated rate-base utility with similar capital program and dividend-oriented profile.
- Alectra Utilities: Ontario Local Distribution Company formed via merger of multiple municipal utilities. Comparable as an OEB-regulated Ontario LDC serving residential and commercial customers in the same regulatory framework as Hydro One's distribution business.
- Toronto Hydro: Local Distribution Company serving Toronto under OEB regulation. Directly comparable in regulated Ontario distribution business model, though smaller and geographically concentrated in Toronto.
- BC Hydro: Crown-owned provincial hydroelectric generation, transmission, and distribution utility in British Columbia. Comparable as a Canadian regulated T&D utility serving a single provincial territory with rate-base growth from grid investment.
- Fortis Inc. Canadian-headquartered regulated electric and gas utility holding company with comparable transmission and distribution operations across North America. Closely comparable in business model (regulated rate-base T&D), capital intensity, and regulated ROE framework.
- EPCOR Utilities: Canadian regulated utility providing electricity distribution, water, and wastewater services across Alberta and the southwestern US. Comparable as a regulated rate-base utility with significant capital program and similar investor profile.
- Canadian Utilities (ATCO): Alberta-based regulated electricity and natural gas T&D utility. Comparable in regulated T&D business model and Canadian utility investor base, though more diversified into gas and infrastructure.
