Construction of the Sainte-Marguerite-3 Hydroelectric Development: Environmental Highlights 1994-2002

Once completed, the Sainte-Marguerite-3 hydroelectric plant will supply 2.7 TWh of electricity. This project has been developed with a concern for optimum integration into the natural environment and local communities, and in a spirit of sustainable development.

Numerous studies provided valuable scientific knowledge about the region's fauna, flora and history—bird nesting areas, for example, and use of the land over the last four millennia. This knowledge should help improve the protection and management of natural resources.

In addition, the application of mitigation and compensation measures has had significant spinoffs for the local economy. It has also made the back country more accessible and financed the improvement of many community facilities.

With Sainte-Marguerite-3, Hydro-Québec has demonstrated that major capital projects like this one can stimulate regional economies in a way that is respectful of the environment. There can be no doubt that the project has improved the local residents' quality of life through the creation of community infrastructures and other spinoffs, which will mean a richer legacy for future generations.
