Krasnoyarsk HPP

Krasnoyarsk Hydroelectric Power Plant (HPP) is one of the largest hydropower plants in Russia, located on the Yenisei River near the city of Divnogorsk, Krasnoyarsk Territory. It is the second biggest hydroelectric power plant in Russia and one of the top ten largest in the world.

The construction of the Krasnoyarskaya hydroelectric power plant began in 1956 and lasted until 1972. The project aimed to provide electricity to the rapidly growing industrial sector in the Krasnoyarsk Territory, such as the Krasnoyarsk aluminium smelter and other energy-intensive production facilities.

Main parameters:

• Installed power capacity: 736.5 MW
• Average annual output: 18,539 million kWh
• Dam height: 124 metres
• Dam length: 1,065 metres
• Hydroelectric unit count: 12

Krasnoyarsk HPP supplies electric power to the Krasnoyarsk Territory and its neighbours. It is the main provider of electric power to aluminium smelters and machine-building facilities in Krasnoyarsk. Furthermore, the hydropower plant helps control the water level in the Yenisei River to protect settlements from floods and support navigation.

The retrofitting of impellers at the Krasnoyarsk HPP began in 2017 under the New Energy Programme. In 2024, the renovation of the sixth hydroelectric unit concluded under the same programme. The HPP will gradually replace the impellers on all 12 of its hydroelectric units.

The New Energy Programme is a major initiative to overhaul and replace key components at four of En+'s largest hydroelectric power plants: Krasnoyarsk, Bratsk, Irkutsk and Ust-Ilimsk. The total amount of investment in the programme is RUB 21 billion.
