About this plant

Situated in Canada, the Rocher-de-Grand-Mère hydroelectric facility holds the distinction of being the 152nd largest power generation facility in the country. With a capacity of 230 MW, it accounts for 0.12% of Canada’s impressive total capacity of 193,190 MW, underscoring its significance within a national energy framework dominated by hydroelectric power. As the 83rd largest hydro plant among 612 across Canada, Rocher-de-Grand-Mère utilizes the gravitational force of falling water to generate electricity, capitalizing on the country’s abundant freshwater resources. This facility not only provides substantial energy output but also exemplifies the environmental benefits of hydroelectric generation, including lower greenhouse gas emissions compared to fossil fuels. The regional energy landscape surrounding Rocher-de-Grand-Mère is characterized by its proximity to several notable facilities, including the Gentilly Nuclear Generating Station, which boasts a robust capacity of 675 MW, and the Bécancour plant, operating on gas with a capacity of 507 MW. Additionally, nearby hydro facilities like Shawinigan-2 and Shawinigan-3, generating 200 MW and 194 MW respectively, contribute to a diverse and resilient energy grid. The presence of these plants illustrates a balanced energy mix in the region, enhancing energy security and reliability. As Canada continues to prioritize renewable energy sources, Rocher-de-Grand-Mère’s role becomes increasingly vital in supporting national energy objectives. Owned and operated under the Hydroelectric banner, this facility has been instrumental since its inception, contributing significantly to the local economy and employment. The commitment to hydroelectric power aligns with Canada’s strategy to reduce carbon emissions and transition to cleaner energy sources. Looking ahead, Rocher-de-Grand-Mère is poised to remain a cornerstone of sustainable energy generation in Canada, facilitating both economic growth and environmental stewardship.
