Ontario Power Generation produces almost half of the electricity that Ontario homes, schools, hospitals and businesses rely on each day. We are committed to ensuring our energy production is reliable, safe and environmentally sustainable for Ontarians today and for the future.
In 2014, OPG burned its last piece of coal to make electricity. This was the largest single action to combat climate change in North America to date. Our two northwestern coal stations were converted to renewable biomass. Now, together with a diverse fleet that includes 65 hydroelectric stations and two nuclear stations, OPG’s power is more than 99 per cent free of smog and greenhouse gas emissions. And we produce this power at about 40 per cent of the cost of other generators.
Looking forward, a key initiative to maintain our clean generation mix is the refurbishment of Darlington Nuclear Generating Station. This project will create thousands of direct and indirect jobs in Ontario and ensure a key part of the province’s infrastructure continues to safely produce reliable, low-cost power for decades to come.
OPG has partnered with Ontario's Indigenous communities on hydroelectric projects, including the recently completed Lower Mattagami project in northeast Ontario. And together with the Taykwa Tagamou Nation, we’re building a new hydroelectric generating station near Cochrane. This $300 million project will employ about 220 workers at peak and add 28 MW of generating capacity.
What We Do
At Sept. 30, 2016, OPG's generating portfolio had an in-service capacity of 17,055 megawatts. We own and operate:
- 2 nuclear stations
- 65 hydroelectric stations on 24 river systems
- 2 biomass stations
- 1 thermal station
- 1 wind turbine
OPG is owner of two other nuclear stations, which are leased to Bruce Power L.P. It is also co-owner but not operator of the Portlands Energy Centre in Toronto and the Brighton Beach gas-fired generating station in Windsor.
- In 2015, about 60 per cent of the power we generated came from our nuclear power plants and about 40 per cent was generated from our hydroelectric stations.
- With more than 200 MW of generating capacity, Atikokan GS is the largest 100 per cent biomass-fuelled power plant in North America.
- OPG was established under the Business Corporations Act (Ontario) and is wholly owned by the Province of Ontario.
- Five of OPG's hydroelectric stations were developed and redeveloped in partnership with Indigenous peoples.
