Eastmain-1-A/Sarcelle/Rupert Project

The result of numerous consultations with the communities concerned, the Eastmain-1-A/Sarcelle/Rupert project has incorporated many environmental protection measures into its design and has taken into account the concerns expressed by the host communities. It will be highly cost-effective, as much of the 8.7 TWh it will add to the company's annual output will be in the form of optimized capacity at the existing La Grande generating facilities. The Eastmain-1-A/Sarcelle/Rupert project is also generating major economic spinoffs for the communities concerned and for Québec as a whole.
