|
|
The Eastmain-1-A/Sarcelle/Rupert project will generate major economic spinoffs for the communities concerned and for Québec as a whole.
This exceptionally cost-efficient project will maximize the generating capacity of several existing powerhouses and thus optimize water use, which is in line with the principles of sustainable development.
The cost of generating electricity, estimated at 5.1¢/kWh in 2011, will benefit future generations.

The project’s main strength lies in the optimization of the generating capacity of some of the existing generating stations in the La Grande complex. Once it has driven the turbines at the Eastmain-1 or Eastmain-1-A and Sarcelle powerhouses, the water will continue on to the existing Robert-Bourassa, La Grande-2-A and La Grande-1 generating stations. |
