Leading Ontario’s Clean Power Future

OPG produces more clean energy, at a lower cost, than any other generator in Ontario. That’s why we are uniquely positioned to contribute to future decarbonization and electrification efforts for the wider provincial economy. Our submission to the 2017 Long-Term Energy Plan outlines our perspective and ideas on how OPG can lead Ontario’s clean power future.

Powering the Future

In 2014, we burned our last piece of coal to make electricity. This was the largest single action to combat climate change in North America to date. Now, with a diverse fleet that includes 65 hydroelectric stations, two biomass station and two nuclear stations, OPG’s power is more than 99 per cent free of smog and greenhouse gas emissions.

In Powering the Future, OPG talks proudly of its role as Ontario’s largest, clean power generator.


To learn more about how we’re making sure our generating stations continue to provide clean, reliable power at about 40 percent of the cost of other generators, please see the information below and throughout our website, and follow us on Twitter @opg.

Our Generation Portfolio

As of March 31, 2017, OPG had 16,205 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.

  • In the first quarter of 2017, the availability of OPG's regulated and unregulated hydroelectric stations were 89.5 per cent and 83.6 per cent, respectively.
  • In the first quarter of 2017, Darlington Nuclear had a capability factor of 85.3 per cent. The capability factor at Pickering Nuclear was 78.5 per cent.
  • OPG is also a co-owner but not an operator of the Portlands Energy Centre and the Brighton Beach gas-fired generating station. In the first quarter of 2017, these stations had a combined generating capacity of 555 MW and production of 0.1 TWh.
