Gentilly nuclear power plant — Canada

Gentilly nuclear power plant is a retired nuclear power station in Quebec, Canada. Its current lifecycle status is “Retired” — so it is not yet, or no longer, generating at full output. It ranks #44 of 1,210 Canada power plants by installed capacity. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, nuclear supplies about 13.1% of Canada's electricity; the national grid averages 191 gCO₂/kWh (77.0% low-carbon) (2025).

In context: how this plant compares

At 941 MW, Gentilly nuclear power plant is around the median nuclear plant in Canada (941 MW). Technically it is described as heavy water light water reactor. Its lifecycle status is Retired; it no longer generates electricity. Nuclear plants split uranium to raise steam with no direct CO₂; they run as steady baseload with very high capacity factors and the longest operating lifetimes of any thermal plant.
