 Made in Ontario.

Across Ontario, from Cornwall to Kenora, OPG and our many partners are working to ensure a sustainable future with clean air, strong economies and liveable communities. That’s because we believe our purpose goes beyond generating electricity. 

Learn more about our projects, our partners, and our amazing people by visiting this special website or watch the video below for a brief look at why we’re committed to keeping Ontario’s air clean.


Our Generation Portfolio

As of Sept. 30, 2018, OPG had 16,218 megawatts (MW) of in-service generating capacity. As one of the largest producers of electricity in North America, OPG diversified, low-cost and low-emission portfolio includes 66 hydroelectric, two biomassone thermal and two nuclear stations, and one wind power turbine. See a map of our operations.
