Douglas Point Nuclear Power Plant
The Douglas Point Nuclear Power Plant began generating electricity in 1967 and continued until 1984. This joint project between Atomic Energy of Canada Ltd. and Ontario Hydro was the first commercial-scale Canada Deuterium Uranium (CANDU) reactor. The Nuclear Power Demonstration (NPD) reactor in Rolphton, Ontario had proven the CANDU concept in 1962 and the 200-megawatt Douglas Point plant, ten times larger than NPD, demonstrated that a CANDU nuclear power plant could be scaled up for commercial power generation. The advances made at Douglas Point provided the province with a growing and reliable energy supply and contributed to the success of larger CANDU plants in Canada and abroad.
