Robert-Bourassa generating station
The Robert-Bourassa generating station, formerly known as La Grande-2 (LG-2), is a hydroelectric power station on the La Grande River that is part of Hydro-Québec's James Bay Project in Canada. The station can generate 5,616 MW and its 16 units were gradually commissioned between 1979 and 1981.[1] Annual generation is in the vicinity of 26500 GWh.[2]

Together with the adjacent 2,106 MW La Grande-2-A generating station (LG-2-A), commissioned in 1991–1992, it uses the reservoir and dam system of the Robert-Bourassa Reservoir to generate electricity. The two plants taken together account for more than 20% of Hydro-Québec's total installed capacity of 36,810 MW in 2009.[1] It is Canada's largest hydroelectric power station, ranks in 12th place on the list of largest hydroelectric power stations and is the world's largest underground power station.[3]
Initially known as La Grande-2, it was renamed after Robert Bourassa who, as Premier of Quebec (1970–1976 and 1985–1994) gave the James Bay Project a vital political impetus.
