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), t is the highest earth filled dam in Russia. It is also the most powerful hydroelectric plant in the country with an underground power station.
