The Bersimis-1 generating station is a dam and a hydroelectric power station built by Hydro-Québec in conjunction with Perini, Atlas and Cartier construction companies on the Betsiamites River, in Lac-au-Brochet, 85 km (53 mi) north of the town of Forestville, Quebec. Construction started in 1953 and the power station was commissioned in 1956 with an initial nameplate capacity of 912 megawatts.
It is the first plant ever built by Hydro-Québec and it has been described as a turning point in the history of electricity in province, paving the way for the takeover of all private utilities by the government-owned corporation in 1963. Three years later, the first plant was followed by a second one, built 30 km (20 mi) downstream. Bersimis-2 entered service in 1959.
With upgrades, a major overhaul in the 1990s and further river diversions, Bersimis-1 installed capacity has been increased over time to its current 1,178 megawatts.
