Background
The 5-unit 300.5MW coal-fired Barnaulskaya-2 power station is owned by Barnaul Generation JSC, which is owned by SUEK.
The plant’s nine turbine units were brought online between 1955 and 1992.[4][5][6] The first phase was commissioned in 1955. In 1958-1959, the second phase of the station was commissioned, with 2 boilers and 2 turbines with a total capacity of 50 MW (2 * 25) (units 3 and 4). In 1961-1964, the third phase of the station was commissioned, 4 boilers and 2 turbines with 52 MW each (units 5 and 6). In 1967, 2 additional boilers were commissioned and 1 turbine unit with a capacity of 50 MW (unit 7). In 1968-1973, the fifth phase was commissioned, 7 boilers and 2 turbines with 55 MW each (units 8 and 9).[7] In 2012-2015, turbine units 8 and 9 were upgraded to newer models, and their capacity increased from 50 MW to 65 MW.[6][7]
In early 2010s, the company decommissioned 4 turbines and 5 boilers, which became economically unjustified.[8] The units retired were the oldest 4 units with 100MW of capacity. This left the plant with 5 active turbine units with total capacity of 300.5MW, according to the company's website and the System Operator's documents.[9][10] Some other sources reported that the plant's capacity is 275MW.[7][6]
The plant supplies electricity and heat to almost half of the city of Barnaul - mainly to its central part.[6]
In 2024, additional equipment was installed at the plant that will allow it to generate electricity also in the summer period without the heat load. [11]
In February 2026, the plant celebrated its 71st anniversary.
Repair, Modernization and Environmental Improvements
In 2025, extensive repair and modernization work was carried out at the plant. Capital overhauls of boilers #7 and #11 were completed at a combined cost exceeding 150 million rubles (approximately $1.7 million), covering defect repairs, replacement of structural components, and capital overhaul of ball drum mills. Boiler #6 underwent an extended scheduled repair along with routine repairs of boilers #10, #12, and #16, with combined investment exceeding 100 million rubles (approximately $1.1 million). Boiler #15 received a scheduled repair including replacement of the water economizer, with investment exceeding 50 million rubles (approximately $560,000).
Turbine units 7 and 8 also underwent scheduled repairs costing over 19 million rubles (approximately $213,000).
As part of environmental improvements, wet ash collectors on boiler #7 were reconstructed at a cost of 53 million rubles (approximately $595,000), raising flue gas cleaning efficiency to 98%. Online emissions monitoring equipment was installed on chimney No. 1, mirroring a system already in trial operation on the 180-metre chimney No. 3; total investment in the monitoring project was approximately 57 million rubles (approximately $640,000). Relay protection and automation systems on the 110 kV overhead line were also modernized at a cost exceeding 16.6 million rubles (approximately $186,000), and cooling tower No. 1 was upgraded at a cost of approximately 10 million rubles (approximately $112,000).[12]
In February 2026, around 15 million rubles (approximately $170,000) were invested in scheduled maintenance of boiler #14, including replacement of the ball drum mill lining; the work was expected to be completed in early March 2026.[13] In March 2026, a further 57 million rubles (approximately $640,000) were allocated for an extended scheduled repair of boiler #13, including replacement of 29.3 tonnes of furnace wall tubes and ball drum mill lining, with completion expected by mid-May 2026.
In total, SGK planned to repair 11 boilers, five turbines, and five generators at the plant in 2026, with boiler #12 and Unit 5 turbine and generator undergoing capital overhaul. Additional 2026 investment projects included replacement of the main steam pipeline on boiler #6, modernization of wet ash collectors on boiler #16, and replacement of transformer T-3. Total SGK investment in repair and modernization of Altai Krai power plants in 2026 was planned to exceed 5.5 billion rubles (approximately $62 million).[14]
Fuel Uncertainty
In the mid 1990s, several of the boiler units were converted to run on natural gas.[6] The System Operator's document released in February 2023 confirmed that the plant can operate on both gas and coal.[10] However according to the company's website it appears that mostly coal is used.[9] Other media sources from 2018 and 2020 suggested the same - coal grade D (subbituminous) is brought to the power plant by rail or road transport from the coal mines owned by SUEK in Khakassiya region or Kemerovo - eg from Chernogorsky coal mine, Vostochno-Beisky coal mine.[15][16] Izykhsky Coal Mine was also mentioned as a coal supplier.[17] 2025 media report suggested that the plant uses bituminous coal.[18]
Chimney Collapse
On April 11, 2021, one of the two operating chimneys at the Barnaulskaya-2 power station collapsed, causing extensive damage to the facility. The power station was forced to shut down operations for about a week. The Investigative Directorate of the Investigative Committee of the Russian Federation for the Altai Territory saw in the incident signs of a crime under Part 1 of Art. 217 of the Criminal Code of the Russian Federation (“Violation of industrial safety requirements for hazardous production facilities, resulting in large damage by negligence”), initiating a criminal case.[19]
The load was redistributed to the other chimney. 3 boilers were connected to the collapsed chimney (boilers No 6, 7 and 9, which was in conservation mode). It was decided to connect boilers 6 and 7 to the other chimney, while boiler 9 was put in conservation, as planned before. The redesign was completed before the start of the new heating season in autumn 2021, together with the dismantling of the collapsed chimney and the repairs of the damage to the facility.[20]
