Laforge-2 generating station

From Wikipedia, the free encyclopedia

Laforge-2 is a hydroelectric generating station on the Laforge River, a tributary of the La Grande River, and is part of Hydro-Québec's James Bay Project. The station can generate 319 MW and was commissioned in 1996. A "run of the river" generating station, it is one of only two generating stations of the James Bay Project that use a reservoir without any major waterlevel fluctuations (the La Grande-1 is the other). Thus, the amount of electricity generated by the station depends almost entirely on the waterflow of the river, which is largely controlled by upstream reservoirs and generating stations.
