The La Grande-1 hydroelectric plant is a run of the river hydroelectric power plant on the La Grande River that is part of Hydro-Québec's James Bay Project. The station can generate 1,436 MW and was commissioned in 1994–1995. 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 water-level fluctuations (the Laforge-2 generating station is the other). Thus, the amount of electricity generated by the station depends almost entirely on the water-flow of the river, which is largely controlled by upstream reservoirs and generating stations.
