The hydropower plant La Grande-1 ( French: Centrale La Grande-1 ) is a run-of-river power plant in the Canadian province of Québec . It is located in the Jamésie region on Réservoir La Grande 1 , a reservoir on the La Grande Rivière river . The river mouth is 37 kilometers to the west, the Robert-Bourassa hydropower station (formerly La Grande-2) 80 kilometers to the east.
The power plant is part of the Baie James hydropower project and has twelve turbines. The installed power of the generators is 1436 MW , the drop height is 27.5 meters. The power station is operated by Société d'énergie de la Baie James (SEBJ), a subsidiary of the state-owned energy supplier Hydro-Québec .
history
Although the power plant was announced in 1972, the complexity of the project meant that it could only be commissioned two decades later. The originally planned power plant location was highly controversial. The Cree , based in the region, obtained a legal stop to planning and forced the provincial government to negotiate. In the agreement signed by the Baie James and North Quebec in 1975, it was agreed to build the power station 34 kilometers further upstream. The agreement also provided for ten turbines with an output of 910 MW.
Meanwhile, the completion of more parts of the Baie James hydropower plant resulted in a sharp increase in the amount of water in the river. The Cree Reserve, located on the Île de Fort George, an island near the river mouth, had to be abandoned due to severe erosion. The Cree who lived there moved in 1981 to the newly built settlement of Chisasibi, eight kilometers away on the left bank .
With the Convention de Chisasibi signed on April 14, 1978 , an additional protocol to the 1975 agreement, the planned power plant output was increased to 1140 MW. Although the construction of the power plant had meanwhile been postponed, a diversion channel was built at the later location in 1979. With a further supplementary agreement, the Cree and the provincial government agreed on November 6, 1986 to install two additional turbines. Construction work finally began in 1988, and commissioning took place in 1994 and 1995.
