POWER GENERATION
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 2010, OPG generated about 60 per cent of the electricity in Ontario or 88.6 terawatt hours (TWh). Our 2010 generation mix consisted of 52 per cent nuclear, 34 per cent hydroelectric and 14 per cent thermal electricity.
Current total generating capacity: 19,049 megawatts (MW)

Throughout 2010, the availability of our hydroelectric stations remained at consistently high levels, finishing the year at 91.9 per cent.
OPG’s nuclear production benefited from improved performance of the Pickering Nuclear. Units 5, 6, 7 and 8 combined, achieved a capability factor of 84.0 per cent in 2009. It also received its best ever peer review from the World Association of Nuclear Operators.
OPG’s thermal stations continued to demonstrate impressive flexibility and responsiveness in 2010 when called upon to meet Ontario’s electricity needs.
