Bratsk Hydroelectric Power Station
The Bratsk Hydroelectric Power Station (also referred to as The 50 years of Great October Dam) is a concrete gravity dam on the Angara River and adjacent hydroelectric power station. It is the second level of the Angara River hydroelectric station cascade in Irkutsk Oblast, Russia. From its commissioning in 1966, the station was the world's single biggest power producer until Krasnoyarsk Hydroelectric Power Station reached 5,000 MW (at 10 turbines) in 1971. Annually the station produces 22.6 TWh. Currently, the Bratsk Power Station operates 18 hydro-turbines, each with capacity of 250 MW, produced by the Leningrad Metal Works ("LMZ", Russian: ЛМЗ, Russian: Ленинградский Металлический завод) in the 1960s.
