The Peace River already has two large hydroelectric facilities (W.A.C. Bennett Dam and Peace Canyon Dam) that rely primarily on the Williston Reservoir for water storage. As the third project on the Peace River, Site C will rely on water already stored in the Williston Reservoir. This means Site C will generate about 35 per cent of the energy produced at W.A.C. Bennett Dam, with only five per
cent of the reservoir area. Construction on Site C began in July 2015. The project remains on-track to have all six generating units in-service by 2025. In 2024, the first of six generating units on the project came into operation, and the reservoir was safely filled, with the water level at the dam site increasing by about 43 metres.
