Portneuf-1 (Chute du 4 Milles) Hydroelectric Power Plant, Quebec, Canada

Portneuf-1 (Chute du 4 Milles) is a hydroelectric power plant located in Quebec, Canada, with a capacity of 7.5 MW. The facility is owned and operated by Innergex, a leading independent renewable energy producer. As a small-scale hydroelectric plant, it contributes to Canada's clean energy mix, leveraging the natural water flow of the region. The plant operates under Canada's robust regulatory framework for hydroelectric power, which includes environmental assessments and water management regulations. In Quebec, hydroelectricity is the dominant power source, supported by stringent provincial guidelines for sustainable water use and fish habitat protection. The technology employed is typical for run-of-river or small reservoir hydro projects, with minimal emissions compared to fossil fuel plants. Portneuf-1 plays a role in supplying renewable energy to the local grid, supporting Quebec's goal of reducing greenhouse gas emissions. Its small capacity means it serves a localized area, providing clean electricity without significant environmental disruption. The plant's operational status reflects its ongoing contribution to the region's energy security and sustainability.

The plant uses hydroelectric power, a renewable source with low direct emissions. However, hydro projects can affect local aquatic ecosystems and water flow regimes. In Quebec, regulations require environmental impact assessments and mitigation measures for fish passage and habitat. The plant's small capacity (7.5 MW) limits its ecological footprint compared to larger dams. Its location in a forested region of Quebec minimizes proximity to dense populations, reducing local air quality concerns.
