About us

Ontario Power Generation is a climate change leader with one of the most diverse generating portfolios in North America.

We’re investing in innovative technologies that will drive clean economic renewal –  including transportation electrification, small modular reactors, energy storage, micro grids, and nuclear refurbishment. And we partner with local, environmental and Indigenous groups to improve the well-being of our site communities.

OPG’s diverse, clean and low-cost electricity generation portfolio in Ontario includes:

  • hydroelectric stations
  • nuclear stations
  • a biomass station
  • a dual-fuelled oil and gas station
  • natural gas-fuelled stations owned and operated by wholly-owned subsidiary Atura Power
  • a solar facility

We operate our stations in a safe, transparent and environmentally-responsible manner. This includes protecting and enhancing the local environment, supporting the provincial and local economies and helping make our site communities better places to live, work and play.

OPG also owns a number of additional facilities in Ontario and the United States.
