Ownership Tree

Background
The eight-unit, 529.7MW coal-fired Biysk-1 power station is owned by Barnaul Generation JSC, which is part of SUEK.
The plant’s eight units were brought online between 1951 and 1994.[3][4]
In May 2020 Unit 7 was switched to run on cheaper D grade coal (Subbituminous). This was the last unit to be switched among all units, the process lasted for 8 years.[5] Previously the power plant ran on more expensive Bituminous grades. The company also mentioned that Subbituminous grade coal has better availability, particularly from the Kuzbass (Kemerovo) region.[5] It appeared that coal is supplied to the power plants in the Altai territory from Zarechny coal mine, Vostochno-Beisky coal mine and Chernogorsky coal mine, all of them are owned by SUEK.[6]
The plant produced 1,789 million kWh in 2020, 1,817 million kWh in 2021[7], 2,164 million kWh in 2022[8], 2,217 million kWh in 2023 and 2,313 million kWh in 2024.[9]
In early 2023 it was reported that one of the chimneys will be dismantled by the end of the year. The chimney was taking out smoke from only 1 boiler. This would leave 2 chimneys in operation.[10] As of February 2024, chimney dismantling was in progress.[11] It appeared that as of late 2024, only two chimneys remained and the company was installing continuous emission monitoring systems on them. [12]
In October 2025, it was reported that repair works on the turbine of Unit 6 and on boiler #11 were nearing completion.[13]
The plant produced 1,941 million kWh in the first 11 months of 2025, representing a 3% increase over the two prior years.[14]
Capacity Increase
In 2021, Siberian Generation Company listed 519 MW for the power station's capacity, but as of June 2022 it was 529.7MW.[4] In May 2021 the power station confirmed increased capacity of 114.9MW instead of the previous 110MW at Units 6 and 7. This was based on the results of the comprehensive testing done in 2021 and reviewed by the System Operator.[15]
The company further stated on its website that it had 7 active turbine units and 8 boilers.[4] Based on the System Operator's document released in February 2023, it appeared that Unit 2 with 25MW was retired earlier as it was not listed as part of installed capacity.[16] Unit 1 with 25MW of capacity remained.[16]
Unit 6 Modernization
In 2025, Unit 6 (turbogenerator No. 6) underwent major reconstruction under Russia's federal DPM-2 capacity supply agreement program. Works included replacement of the high-pressure cylinder and full replacement of the generator, as well as installation of a new 125,000 kVA power transformer and a modern automated process control system. Total project cost was 1.6 billion rubles (approximately $18 million).[14] From 28 December 2025 to 3 January 2026, comprehensive commissioning tests were completed, confirming Unit 6's installed capacity at 111.5 MW. Test results were submitted to the System Operator.[17]
Following the completion of Unit 6 modernization in early 2026, the station's total installed capacity was expected to be updated by the System Operator based on the commissioning test results.[17] The System Operator's planning documents for 2025–2031 already listed Unit 6 at 114.9 MW.[18]
2025–2026 Repairs and Maintenance
In 2026, SGK planned to repair eight boilers, seven turbines, and seven generators at the station, with capital overhauls on one boiler and two turbine-generator sets. Investment projects included replacement of the heat exchanger tube system on turbogenerator No. 7 and modernization of wet ash collectors on one boiler. In February 2026, the rotor of turbogenerator No. 3 (50 MW, commissioned 1965) was extracted and transported to the ELSIB plant in Novosibirsk for capital overhaul, with full completion of works on the unit expected by July 2026.[19][20]
Accidents
In February 2021, two workers at the Biysk-1 power station received severe burns when coal dust leaked into the workshop and ignited. Both workers ultimately died from their wounds. A criminal case was initiated to investigate violation of labour protection requirements resulting in the death of a person by negligence.[21]
