SayanoShushenskaya

Sayano-Shushenskaya is a hydroelectric power station on the Yenisey River, located near the village of Cheryomushki in Krasnoyarsk Krai, Russia. It is the largest power station in Russia and the sixth largest in the world. The construction of the dam began in 1963 and the first power unit was launched in 1978. The power station was fully commissioned in 2000.

The dam is a double-curvature arch dam, 245 meters (804 feet) high and 1,066 meters (3,497 feet) long. It forms the Sayano-Shushenskoye Reservoir, which has a volume of 31.3 cubic kilometers (25,400,000 acre-feet). The power station has ten Francis turbines, each with a capacity of 640 megawatts, for a total installed capacity of 6,400 megawatts.

The Sayano-Shushenskaya power station plays a crucial role in the Russian energy sector, supplying electricity to industrial consumers in Siberia and the Urals. It also contributes to flood control and provides water for irrigation. The power station has been a subject of interest due to its massive scale and its environmental impact. In 2009, a catastrophic accident occurred at the station, causing significant damage and loss of life. Following the accident, extensive repairs and upgrades were undertaken to improve the safety and reliability of the power station.
