Ownership Tree

Background
The eight-unit, combined heat-and-power 1,110-MW coal-fired Irkutsk-10 power station produces heat and power for industrial enterprises and the population of the cities of Angarsk and Meget.[4][5][6] Heat is said to be supplied to two poultry farms, while electricity is supplied to the grid.[7]
The plant’s eight units were brought online between 1959 and 1962.[8][9]
The plant has 16 boilers, four for each chimney. Two boilers form a double unit to work with each turbine, and operate independently. This confguration is different from other plants of the parent company and it is the only plant in Irkutsk with such layout.[7] In addition, the boilers are of the Ramzin system and they do not have a drum in which the water is separated from the steam. This process occurs in another part of the device. Such boilers, according to the director of CHPP-10, are several times less in metal consumption, but more manoeuvrable in terms of performance and cost less.[7]
The plant produced 3,100 million MWh of electricity in 2020[10], 3,000 million MWh in 2021, 4,600 million MWh in 2022[11], 4.9 million MWh in 2023, 5.4 million MWh in 2024[12] and 5.4 million MWh in 2025.[13]
Ownership
The plant is owned by Baikal Energy Company (a subsidiary 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.[14][15]
Irkutskenergo announced that it first would sell its power plant holdings to its subsidiary Baikal Energy Company for 27 billion roubles.[16] The sale was finalized and these holdings were transferred on Sep. 1, 2020.[17] 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; after acquisition, Gazprom would facilitate the conversion of these plants to gas.
As of May 2023 and April 2024, there was no other news on the change of ownership.
Modernization
In September 2020, En+Group announced that it would spend RUR 1.1 billion to modernize three units at the Irkutsk-10 power station.[18] This will include installation of three new turbines with combined capacity of 450 MW, which would replace some of the existing turbines.[6] By 2025, a total of four new turbines would be installed. The first stage of modernization begun in September 2020 including some work on the turbine and boiler of unit 1, expected to be completed by 2022, which would increase the unit's capacity by 5 MW.[6] However it was not clear whether this capacity increase has been confirmed and the System Operator's document published in early 2023 and late 2024 did not refer to capacity increase at Unit 1.[19][20] As of December 2025, System Operator's documents stated that the capacity of Unit 1 would remain at 60MW until at least 2030.[21]
A media source from April 2023 reported that EN+ wanted to cancel several planned modernization projects, including at Irkutsk-10 power station, without incurring penalties from the System Operator.[22] Cost increases for some projects exceeded 300%. However the Ministry of Energy planned to reject this request in regions with energy deficit such as Irkutsk.[23]
As part of the KOMMod modernisation programme, En+ Group carried out a phased replacement of boiler and turbine equipment at the station. By early 2024, the new generator on Unit 2 turbine had been commissioned, boiler No. 4 had been replaced, and work on boiler No. 16 was nearing completion. In 2024, work was planned to be completed on boiler No. 6 and Unit 8 turbine, with the first stage of modernisation of boiler No. 13 and Unit 7 turbine generators to begin thereafter. According to the station's director, the modernisation involved complete replacement of the furnace volume of the boilers — only the boiler frame was retained.[24][25]
As of April 2024, the modernization program appeared to be in full swing. Two projects were nearing completion, two were expected to last until 2027. A new generator on turbine Unit 2 was put into operation and Boiler No. 4 has been replaced. In 2024, the company targeted to replace turbine Unit 8 and complete work on boiler No. 16. In 2023 investments into the plant reached RUB 367 million (ca USD 4 million) and RUB 380 million will be invested in 2024.[7][26][27]
As of August 2024, works were ongoing to replace generator of Unit 8, with works planned to continue until the end of 2024.[28]
As of July 2025, a new generator stator was installed on Unit 7 as part of the KOMMod modernization program, replacing equipment that had been in service for more than 60 years. The upgraded unit was scheduled to be commissioned before the start of the 2025–2026 heating season. The new generator was expected to significantly improve the plant’s reliability and reduce the need for future maintenance.[29]
There were no further updates as of April 2026.
Safety Violations
In April 2026, an inspection by Rostekhnadzor, Russia's federal industrial safety regulator, identified 84 industrial safety violations at the station, including boilers operated without mandatory safety assessments after repairs, missing welding records, and boilers with burnouts, insulation failures, and leaks. The operating company and responsible officials were subject to administrative penalties.[30]
