So, some interesting statistics from 2023 thanks to the IAEA:

Bruce 1, refurbished and returned to service in 2012 produced 7,022.43GWh, yielding a 101.1% capacity factor
Bruce 2, refurbished and returned to service in 2012 produced 6,992.40GWh, yielding a 102.7% capacity factor

Both units have slightly different nameplate ratings, with Bruce 1 being bumped to 811MWe at some point during the year, while Bruce 2 remains at 777MWe. Both units are currently thermally derated to 92.5%, along with the rest of the Bruce A units. They were originally rated for 740MWe, but are oversized on the steam side because they produced process steam to heat the site, feed the Bruce Energy Centre and run the massive heavy water plant. The units should be producing 890MWe by around 2030 as part of the plan to increase the combined output of the 8x Bruce A/B units to a nameplate capacity of over 7,000MWe.

The Bruce complex has now produced 1,564.6TWh of electricity. It was the first plant to produce 1PWh, beating out Gravelines in France, and will be the first plant to produce 2PWh. This makes Bruce the most productive thermal plant on earth. Planning efforts are underway for the construction of Bruce C, which looks to increase the capacity of the site by up to 4,800MWe, driving total nameplate to over 11,000MWe and making it the largest thermal power plant ever constructed. Original plans by Ontario Hydro were for 16 units at the site, Bruce A/B/C/D.

Currently there is some competition between the new CANDU Monark design, from Atkins Réalis (formerly SNC Lavalin) and the Westinghouse AP1000, since Westinghouse is now owned by two Canadian companies, Cameco, the uranium juggernaut, and Brookfield.
