In 2020, the Darlington nuclear power plant in Ontario achieved a capacity of approximately 3,700 megawatts. The electrical output of Bruce A and Bruce B was also above 3,000 megawatts in 2020. These three power plants have four units. In comparison, Point Lepreau plant had a capacity of only 700 megawatts, but this plant accounts for one single reactor.
