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 2012, OPG generated about 60 per cent of the electricity in Ontario or 83.7 terawatt hours (TWh).
