The Boguchany Dam (Russian: Богучанская ГЭС) is a large hydroelectric dam on the Angara River in Kodinsk, Krasnoyarsk Krai, Russia. It has an installed capacity of 2,997 MW. Construction of the power plant was completed when a ninth and final generator was brought online in January 2015.
Preparatory works for construction started in 1974. The design was performed by Hydroproject in 1976. Construction of the power station started in 1980 but was suspended in 1994 due to the lack of financing. Work on the project resumed in 2005 when RAO UES (then owner of RusHydro) and Rusal agreed to develop the project jointly. Construction restarted in 2007. The first turbine was dispatched in 2008. The dam began to fill its reservoir in May 2012 and by August of that year, the first two turbines were installed. They later became operational on 15 October 2012. The third generator began operations later the same month and the fourth was commissioned on 13 January 2013.
The Boguchany Dam is a 2,587 m (8,488 ft) long dam of combined type, which includes reinforced concrete 774 m (2,539 ft) long gravity segment for power station building and 1,813 m (5,948 ft) long rock-fill segment with asphaltene-concrete diaphragm throughout all its length. The dam was equipped with ship lock until 2010, later it was closed and its former location was included in concrete gravity section.
The power station consists of nine Francis turbines with a capacity of 333 MW each. It generates 17.6 TWh of electricity per year. Turbines are manufactured by Power Machines. The power station is owned and operated by Boguchanskaya GES, a joint venture of RusHydro and Rusal, who also built it. Energy from the plant is partly used by the Boguchany Aluminium Smelter.
