As one of the largest producers of electricity in North America, Ontario Power Generation operates 65 hydroelectric, 5 thermal and 2 nuclear stations producing more than 19,000 megawatts of electricity.
In fact, OPG owns one of the most diversified, low-cost and low-emission portfolios in North America. Our commitment is to continually improve the efficiency of our generating stations so that Ontario has the power it needs, when it needs it.
In 2012, OPG generated about 60 per cent of the electricity in Ontario or 83.7 terawatt hours (TWh).
Current total generating capacity: 19,049 megawatts (MW)
Throughout 2012, the availability of OPG's regulated and unregulated hydroelectric stations remained at high levels of 91.4 per cent and 91.1 per cent, respectively.
In 2012, Darlington Nuclear performed well with a capability factor of 93.2 per cent. The capability factor at Pickering Nuclear improved to 77.8 per cent.
OPG’s thermal stations continued to demonstrate impressive flexibility and responsiveness in 2012 when called upon to meet Ontario’s electricity needs.
