Background
The plant’s six units were brought online between 1978 and 1990. The plant is a cogeneration plant, powering Ilim Timber's Ust-Ilimsk sawmill. It also provides electricity and heat to the residential section of the city of Ust-Ilimsk.[3][4][5] In addition to that, the plant provides water supply and sewage services to the city of Ust-Ilimsk.[6] In 2004 one of the plant's 50-MW units was retired, due to insufficient demand for electricity. In 2011 the unit was transported to the Novo-Irkutsk power station where it was re-commissioned in 2013.[7]
In the 2021 Sustainable Development report, EN+ reported that the installation of electrostatic filters has started at Ust-Ulimskaya power plant.[8]
The plant produced 700 million kWh of electricity in 2020, 800 million kWh in 2021[8], 900 million kWh both in 2022[9] and 2023,[10]
and 1,200 million kWh both in 2024[11] and 2025. [12]
Ownership
Ust-Ilimskaya CHP power station is owned by Baikal Energy Company, a subsidiary of Irkutskenergo, which in turn is owned by En+Group.
In December 2019 Irkutskenergo announced that it planned to sell its coal plants and other coal assets, possibly to Gazprom Energoholding LLC, which would facilitate the conversion of these plants to gas.[13][14] As a first step the power plant holdings would be transferred to its subsidiary Baikal Energy Company for 27 billion rubles.[15] The sale was finalized and these holdings were transferred on Sep. 1, 2020.[16] Baikal Energy Company would then be in a position to sell the assets to another company. The transfer of assets was planned to happen in stages and be complete by 2024. Gazprom Energoholding LLC emerged as a potential buyer.[16] As of May 2023 and December 2024, there was no other news on the change of ownership.
