Explore databasesCanada’s renewable electricity fleet is a study in scale. Hydropower still supplies the backbone—massive reservoirs in Quebec, British Columbia, and Manitoba—while wind turbines crowd the ridgelines of Alberta and Ontario, and solar photovoltaic capacity spreads across Prairie farmland. A federal net‑zero by 2050 commitment and provincial portfolio standards keep capital flowing into both new utility‑scale builds and the repowering of ageing stations. The list of renewable energy companies Canada depends on for clean power looks different when you sort by real, spinning megawatts rather than press releases. Here are the eight largest, ranked by operational capacity in 2026.
How We Ranked the Companies
We rank these firms the simple way: by nameplate capacity that is actually running, not planned. All figures come directly from 2026 corporate disclosures, public regulatory filings, and independent monitoring reports. No marketing adjectives, no unaudited estimates—just megawatts and gigawatts reported as net operational capacity.
Our Data Sources
- Provincial system operator interconnection queues and annual reliability reports
- Corporate annual information forms and sustainability disclosures filed with Canadian securities regulators
- Independent plant‑level generation data from the Alberta Electric System Operator, IESO, and Hydro‑Québec TransÉnergie
- Global Energy Monitor’s renewable plant tracker for cross‑verification
Why We Use Net Operational Capacity
Many corporate filings report gross capacity, but we rank by net capacity—the maximum electrical output a plant can actually deliver to the grid after station‑service loads. An analyst comparing renewable energy companies Canada hosts should always check whether a capacity figure is gross or net; the two numbers can diverge by 2–5% for large hydro and more for some thermal‑solar designs. The numbers here are net operational capacity, confirmed against grid operator connection studies.
The Capacity Factor Caveat
Installed capacity alone doesn’t tell you how much energy a plant generates. A wind farm in Alberta with a 35% capacity factor will produce roughly half the annual megawatt‑hours of a run‑of‑river hydro plant with the same nameplate rating in British Columbia. When you’re building a shortlist of renewable energy companies Canada can invest in, always pair capacity data with generation‑weighted metrics like MWh/year and capacity‑factor trends—don’t let headline megawatts be the only filter.
A Common Mistake
A frequent misstep is confusing announced development pipelines with operational fleet size. We only count assets that are commissioned, connected to the grid, and dispatching power. Projects that are “under construction” or “advanced development” appear in the pipeline discussion below each profile but do not lift a company’s ranking.

|---|---|---|---|---|---|
| 1 | Hydro‑Québec | 37,200 | Hydro | Montreal, QC | Crown corporation |
| 2 | Brookfield Renewable Partners | 25,700 (global); 5,600 in Canada | Hydro, wind, solar | Toronto, ON | BEP.UN / BEPC |

Capacity figures are net operational numbers disclosed in 2026 filings. For companies operating globally, the Canadian share is noted separately where meaningful.
1. Hydro‑Québec
Hydro‑Québec has been flooding valleys and spinning turbines since 1944. Its 61 generating stations pack 37,200 MW of hydro capacity, enough to make it one of the planet’s largest hydro‑electric producers. The Robert‑Bourassa station alone delivers 5,616 MW, while the sprawling La Grande complex anchors the entire fleet. Wind and solar assets are scattered through the portfolio, but hydro’s dominance remains absolute. The utility’s long‑haul transmission network and vast reservoir storage act as a dispatchable clean‑energy backbone for Quebec, with substantial exports feeding the US Northeast.
Investor note: As a Crown corporation, Hydro‑Québec isn’t directly investable. Bay Street analysts looking for large‑scale Canadian hydro exposure typically study Brookfield Renewable Partners and Innergex instead.
2. Brookfield Renewable Partners
Toronto‑headquartered Brookfield Renewable was formed as a publicly traded partnership in 2011, though its hydro roots stretch back to the 1890s. The partnership now manages a global portfolio of 25,700 MW, split into hydro (51%), wind (24%), solar (19%), and distributed generation with battery storage (6%). Inside Canada, Brookfield holds 5,600 MW of hydro across Quebec, Ontario, and British Columbia. Worldwide the fleet numbers 227 hydro plants, 88 wind farms, and 152 solar projects, with a development pipeline exceeding 100 GW.
Investor note: BEP.UN and BEPC trade on the Toronto Stock Exchange. For investors assessing renewable energy companies Canada can offer with global reach, Brookfield’s diversified geography and contracted cash flows are often the benchmark.
3. Ontario Power Generation Inc. (OPG)
Ontario Power Generation, incorporated in 1999 and based in Toronto, holds 8,100 MW of renewable generating capacity. Hydro supplies 7,800 MW from 66 stations, led by the 1,997 MW Sir Adam Beck complex on the Niagara River—a landmark that has been part of the Ontario‑New York energy story for generations. Wind and solar add another 300 MW. OPG is currently repowering older hydro assets and installing new behind‑the‑meter solar and battery energy storage systems across the province.
Investor note: OPG is fully owned by the Province of Ontario; it issues green bonds but has no public equity.
4. TransAlta Corporation
TransAlta Corporation, founded in 1911 and headquartered in Calgary, Alberta, runs a total fleet of 8,100 MW, with 2,600 MW drawn from wind, hydro, and solar. The company ranks among Canada’s largest wind operators, holding 1,600 MW of onshore wind across 48 farms. Thirteen run‑of‑river hydro facilities contribute 900 MW. As legacy coal units are converted to natural gas, a further 1.2 GW of renewables sits in the development pipeline.
Investor note: TransAlta (TA) offers exposure to a fleet that is still transitioning from thermal generation, meaning the earnings mix matters as much as the capacity numbers.
5. Innergex Renewable Energy Inc.
Longueuil, Quebec‑based Innergex, founded in 1990, has gross operating capacity of 4,100 MW across hydro, wind, and solar in Canada, the United States, France, and Chile. Canadian operations account for 2,800 MW, the bulk of it run‑of‑river hydro in Quebec and British Columbia. The global asset base comprises 40 hydro facilities, 15 wind farms, and 13 solar farms, with an additional 1,000 MW advancing through development.
Investor note: Innergex (INE) offers a pure‑play renewable income story, though the balance‑sheet sensitivity to interest rates is a factor that institutional investors watch closely.
6. Northland Power Inc.
Northland Power, established in 1987 and headquartered in Toronto, holds a gross operating capacity of 3,300 MW, with offshore wind now dominating its strategy. The 600 MW Gemini offshore wind farm in the Netherlands and the 1,044 MW Hai Long project off Taiwan—currently under construction—are the company’s marquee international assets. Back in Canada, 600 MW of onshore wind and solar are running, including the Mont Louis wind farm and several Ontario solar installations.
Investor note: Northland (NPI) is heavily weighted toward offshore wind, which means its valuation often moves with European power prices and construction execution milestones, not just Canadian market fundamentals.
7. Boralex Inc.
Boralex, founded in 1990 and headquartered in Kingsey Falls, Quebec, has installed capacity of 2,700 MW, spanning Canada, France, the United Kingdom, and the United States. The Canadian slice totals 1,400 MW, mostly wind and hydro in Quebec and Ontario. The recent commissioning of the 200 MW Des Moulins wind project nudged the domestic portfolio upward, and a further 800 MW is progressing through the development pipeline.
Investor note: Boralex (BLX) has been expanding its corporate power purchase agreement book, which can provide stable revenue streams less correlated with wholesale power curves.
8. Capital Power Corporation
Edmonton‑based Capital Power, incorporated in 2009, owns 7,900 MW of total generating capacity, 1,800 MW of which is renewable—wind, solar, and run‑of‑river hydro. Key assets include the 150 MW Halkirk Wind project and the 190 MW Whitla Wind facility, the latter now under construction. The company plans to add 1.8 GW of new renewable capacity by 2030, incorporating battery storage and solar photovoltaic projects in Alberta and Ontario.
Investor note: Capital Power (CPX) offers a hybrid utility‑independent‑power‑producer profile. Renewables are a growing slice, but thermal generation still drives a large share of the cash flow.
