- Sayano-Shushenskaya hydroelectric station
Sayano-Shushenskaya hydroelectric station ( _ru. Сая́но-Шу́шенская гидроэлектроста́нция)is located on the
Yenisei river nearSayanogorsk inKhakassia .General information
As of 2007, it is the largest power plant in Russia and 5th world largest ( by installed capacity ) hydroelectric plant. It was opened in 1978. Its installed capacity is 6,400 MW, average annual production is 23,500 GWh, peaked in 2006 with 26,800 GWh.Station constructions include dam, power plant building located near dam, and an additional spillway under construction. The gravity arch type dam is 245 m high, has crest length of 1066 m, crest width of 25 m, base width of 110 m and maximum head of 220 m. The dam consist of solid left-bank dam 246.1 m long, power dam 331.8 m long, spillway dam 189.6 m long and solid right-bank dam 298.5 m long. It is the only gravity-arch dam in Russia of that size, the only other gravity-arch dam is much smaller.
Currently it operates 10 hydro turbines, each with capacity of 640 MW at 194 m head.
The dam forms
Sayano-Shushenskoe Reservoir with total capacity of 31.34 km³ and useful capacity of 15.34 km³ and surface area of 621 km².The plant was designed by Leningrad-based "
Hydroproject " ( _ru. «Гидропроект») institute.Economic value
The station is the largest one to conver peak consumtion in the Unified Energy Systems of Russia and Siberia. One of the largest local consumers is
Sayanogorsk Aluminium Plant . In wet years about 1600 — 2000 GWh are lost due to lack of high-voltage line transmission capacity, and some water is run bypassing turbines. To avoid it, new aluminium plant was launched December 15, 2006; completion expected by the end of 2007.ee also
