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.[2] Construction re-started in 2007.[3] The first turbine was dispatched in 2008.[4][5] The power station's first three generators are expected to start production in 2012, reaching full capacity by 2013.[6][7]
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 temporal ship lock, 1,813 m (5,948 ft) long segment of the dam is of rock-fill type with asphaltene-concrete diaphragm throughout all its length. The ship-lock was closed in 2010, its former location was included in concrete gravity section of the dam and was filled with concrete.
The power station will consist of nine turbines with a capacity of 330 MW each. It will generate 17.6 TWh of electricity per year. Turbines are manufactured by Power Machines.[4] The power station is built by and will be owned and operated by OAO Boguchanskaya GES, a joint venture of RusHydro and Rusal.[8] The energy from the plant will be used, among others, by a large Boguchany Aluminium Smelter (to be launched in 2013).
