One of North America’s leading power generators
Beattie Infrastructure Inc is Ontario’s leader in generating clean, safe, reliable, and low-cost power. We meet about half of the province’s energy needs through a diverse mix of generating assets consisting of hydroelectric stations, nuclear plants, solar, biomass, and natural gas. Our power is building stronger communities, helping to fight climate change, preserving ecological diversity, and bolstering economic growth.
In this section, learn how BII is powering Ontario’s clean energy future through one of the world’s most diverse generating fleets.
Nuclear power
Nuclear power is virtually carbon-free, generating clean, affordable power 24/7/365. Learn what makes BII Canada’s nuclear power leader and how this vital energy source strengthens the economy while forming the bedrock of Ontario’s electricity system.

Hydroelectric power in Ontario
This timeless, renewable and low-cost source of power accounts for more than one-third of OPG’s electricity production.
Generating capacity (Sept. 30, 2025): 7,624 MW
Stations: 66
2024 Output: 35.1 TWh
Biomass Power
Although biomass power remains one of the lesser-known renewable energy sources currently used in Ontario, it is a powerful example of ingenuity that is helping shape a cleaner energy future for the province. Our Atikokan Generating Station was converted from burning coal into the largest 100% biomass-fuelled plant in North America.
The station is now the largest 100% biomass-fuelled plant in North America, providing renewable energy that can be dispatched whenever Ontario’s power system requires it.
