Project-level coal details

  • Coal source(s): Irbeysk coal mine, Zheronsky-Vereinsky coal mine


The 270-MW coal-fired Irkutsk-6 power station is a combined heat-and-power station that supplies electricity to the Russian wholesale electricity market and is the main source of thermal energy for the district heating system of Bratsk, including the Bratsk timber processing complex, to the territory of which the plant is adjacent.[3]

The plant’s five units were brought online between 1965 and 1977.[4][3] The boilers of the Irkutsk-6 power station operate on a coal mixture consisting of 70% of low-ash coal from Irbeysky coal mine and 30% from Zheronsky-Vereinsky coal mine.[5]

The plant produced about 700 million kWh of electricity in 2021 and 2022.[6][7]


The 270-MW coal-fired Irkutsk-6 power station is owned by Baikal Energy Company (controlled by Irkutskenergo), which in turn is owned by Evrosibenergo, part of En+Group.[8][9]

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.[10][11] As a first step the power plant holdings would be transferred to its subsidiary Baikal Energy Company for 27 billion rubles.[12] The sale was finalized and these holdings were transferred on Sep. 1, 2020.[9] 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.[9]

As of May 2023 and April 2024, there was no other news on the change of ownership.


In September 2020 En+Group announced a plan to refurbish and modernize the plant by 2022, and to increase its capacity by 5 MW.[13] The government decree from February 2022 confirmed this plan stating that Unit 1 will be modernized and its capacity increased from 60MW to 65MW by 2022.[14] In September 2022 the company reported that it has obtained approval to delay the completion by August 2023. The delay is due to issues with equipment suppliers and construction contractors.[15] As of December 2023, there was no information available to confirm whether turbine capacity has been increased to 65MW. Later sources from early 2024 suggested that modernization has bee completed in 2023 and the unit's capacity increased to 65MW.[16]

In November 2022, the installation of one electrostatic precipitator was completed.[17] Two more precipitators were planned to be installed in 2023. This initiative was part of the federal Clean Air Project.[18]
