The Bersimis-2 generating station is a dam and a run-of-the-river hydroelectric power station built by Hydro-Québec on the Betsiamites River, in Lac-au-Brochet, 66 km (41 mi) north of the town of Forestville, Quebec. Construction started in 1956 and the power station was commissioned in 1959 with an initial nameplate capacity of 655 megawatts.
It is the second of two plants built by Hydro-Québec on the Betsiamites. Bersimis-2 was preceded by Bersimis-1, built 30 km (20 mi) upstream between 1953 and 1956. With upgrades and further river diversions, Bersimis-2's installed capacity has been increased over time to its current capacity of 869 megawatts.
