Arch-Gravity dam · Khakassia, Russia
Sayano-Shushenskaya Dam is an arch-gravity dam on the Yenisey in Khakassia, Russia, standing 242 m (794 ft) high and completed in 1978. It carries an installed hydroelectric capacity of 6,400 MW. The structure impounds Sayano-Shushenskoe Reservoir.
The Sayano-Shushenskaya Dam (Russian: Сая́но-Шу́шенская гидроэлектроста́нция, Sayano-Shushenskaya Hydroelektrostantsiya) is located on the Yenisei River, near Sayanogorsk in Khakassia, Russia. It is the largest power plant in Russia and the 12th-largest hydroelectric plant in the world, by average power generation. The full legal name of the power plant, OJSC [Open Joint-Stock Society] P. S. Neporozhny Sayano-Shushenskaya HPP [hydro power plant], refers to the Soviet era Minister of Energy and Electrification Pyotr Neporozhny. As of 2009 the head of the power plant was Valery Kyari.

History
The decision to build the power station was taken in 1960. On 4 November 1961, geologists reached the area, and an exact location was chosen. Construction started in 1963 and the first turbine went online on 18 December 1978. The plant became fully operational in December 1985. It was partially reconstructed in 1987 and in 1991. The plant was designed by the Leningrad (now Saint Petersburg) branch of the Hydroproject (Гидропроект, Gidroproyekt) institute, Lenhydroproject.
Following the collapse of the Soviet Union, the power plant was privatized in 1993, with RAO UES becoming the main shareholder. In April 2003, the Government of Khakassia by the initiative of the governor Alexei Lebed filed a suit to invalidate the deal.
Description
The plant is operated by RusHydro. As of 2009, it was the largest power plant in Russia and the world's sixth-largest hydroelectric plant by average power generation. It provides more than a quarter of RusHydro's generation capacity. The plant operated ten type РО-230/833-0-677 hydro turbines manufactured at the Leningradsky Metallichesky Zavod, each with a capacity of 640 MW at 194-metre (636 ft) head. The total installed capacity of the plant is 6.4 GW; its average annual production is 23.5 TWh, which peaked in 2021 at 29.4 TWh.
The dam is constructed to "safely" withstand earthquakes up to 8 on the Richter scale, and was recorded by the Guinness Book of World Records for the strongest construction of its type.
