Ownership Tree

Background
The plant was initially built with an intention to provide power for the Argansk oil refinery.[2] Today the combined heat-and-power station is providing steam, heat and electricity to local residents, as well as to the largest industrial enterprise in the city - the Angarsk Petrochemical Company (Argansk oil refinery).[2]
The plant’s eight units were brought online between 1963 and 1983.[3]
The plant's installed capacity is 540MW with 8 operating units.[4][5][6][7]
The plant produced 1,800 million kWh of electricity in 2021[5], 2,000 million kWh in 2022[8], 2,500 million kWh in 2023, 2,000 million kWh in 2024[9] and 1,700 million kWh in 2025.[10]
Ownership
The eight-unit, 540-MW coal-fired Irkutsk-9 power station is owned by Baikal Energy Company (ООО Байкальская энергетическая компания), a subsidiary of Irkutskenergo which in turn is owned by Evrosibenergo, part of En+Group.[11][4]
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.[12][13][14] The sale was finalized and these holdings were transferred on Sep. 1, 2020.[15] 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.[15]
As of May 2023 and December 2024, there was no other news on the change of ownership.
Incidents
On 7 December 2025, a boiler failure caused by a fire and explosion — in which the station's fire suppression system performed inadequately — left over 167,000 residents of Angarsk without heat at approximately −30°C. A state of emergency was declared, and the Investigative Committee opened a criminal investigation. Heat supply was fully restored within several days.[16][17]
Following the accident, the government of Irkutsk Oblast rejected BEK's request to raise tariffs for modernisation, noting that the company had underspent previously approved repair funds of 749 million rubles (approximately $8 million) in 2021–2023. BEK's investment programme for 2025–2028 included 2.2 billion rubles (approximately $24 million) for reconstruction of Irkutsk-9 and Irkutsk-10 power stations.[18]
Decommissioning of the Irkutsk-9 Station 1 power station
In May 2021, Irkutsk-9 Station 1 power station was decommissioned, and its load was transferred to the Irkutsk-9 power station. The transfer project cost RUR 3.45 billion and took 7 years to complete, from 2013 until 2021.[19][20]
