Kolyma Hydroelectric Station is located on the Kolyma River in the village of Sinegorye, Yagodninsky District, Magadan Oblast Russia. It has an installed power generation capacity of 900 MW.^[2] Kolyma HPP is the basis of the energy system of Magadan Oblast; it produces about 95% of the electricity in the region. It is the upper stage of the Kolyma cascade, while the lower one (Ust-Srednekan Hydroelectric Plant) of 570 MW installed capacity is under construction.

Construction began in 1974 and the first generator was commissioned in 1982, the last in 1994. Construction of the Kolyma HPP was carried out in the harsh climatic conditions in the zone of permafrost. At 134.5 m (441 ft), it is the highest earth filled dam in Russia. It is also the most powerful hydroelectric plant in the country with an underground power station.
