The Boguchanskaya GES is a hydropower plant under construction on the Angara River in the Krasnoyarsk district Territory. It is included in the Angara cascade of hydropower plants. Its location is the town of Kodinsk, Kezhemskiy district of the Krasnoyarsk Krai. The construction of HPP began in 1980, preparatory works began in 1974. According to the approved project the plant must have the hydroelectric capacity of 3,000 MW. The building of HPP should include 9 radial-axial generating units with the capacity of 333 MW.
The Boguchanskaya GES was designed by the institute “Hydroproject”. Preparational works for plant construction began in 1974. In 1987 the channel of the Angara was blocked by a concrete dam with a temporary gateway.
The construction of the plant was in fact frozen from 1994 to 2005 due to the lack of funds. In 2004 58% of plant facilities were ready to work.
The hydroelectric power station building is of great importance for the development of the Lower Angara and Siberian economic region in whole. More than half of the electricity generated by the plant will be used during construction of an aluminum plant.
A ridge mark on a concrete dam is 214 m, the building height is 96 meters, the length of the ridge – 828.7 m.
Pressure constructions of the hydroelectric power station (the length of the waterfront is 2587 m) will create a large reservoir Boguchanskoye with the area of 2,326 km ².
In preparing of the reservoir bottom 149.5 thousand hectares including 29.6 thousand hectares of farmland are flooded and it is necessary to resettle 12,2 thousand people (some people have already resettled) from 31 settlements.
According to the plant project the height of the head race above sea level should reach 208 m, an intermediate reservoir level during the work of first generating units must be 185-186 m.
