Sainte-Marguerite-1-1a Hydroelectric Power Plant, Quebec, Canada

Sainte-Marguerite-1-1a is a hydroelectric power plant located in Quebec, Canada, with a capacity of 30.5 MW. The facility is owned by a joint venture between Innergex Inc (50%) and Desjardins Group Pension Plan (50%). As a run-of-river or reservoir-based hydro plant, it contributes to Canada's clean energy mix. The plant operates under Canada's federal and provincial regulations, including the Canadian Environmental Protection Act and Quebec's environmental standards for water management and fish habitat protection. Hydroelectric plants in Canada typically have low emissions but require careful management of water flows and ecological impacts. This facility plays a role in supplying renewable electricity to the Quebec grid, which is predominantly hydro-powered. Its modest capacity supports local energy needs while aligning with Canada's goals for low-carbon power generation.

Hydroelectric power generation in Quebec benefits from abundant water resources but can affect local aquatic ecosystems and water flow regimes. The Sainte-Marguerite-1-1a plant's operations are subject to environmental monitoring to mitigate impacts on fish populations and river habitats. The region's boreal forest setting provides a natural buffer, though reservoir creation may alter local landscapes.
