Background
The power plant is owned by Sevkazenergo JSC, which is part of the Central Asian Electric Power Corporation JSC (CAEPCO).[4] The plant is located in Petropavlovsk, North Kazakhstan Region, Kazakhstan.[5][6]
The combined heat and power station supplies heat to residents in the North Kazakhstan region, including the Petropavlovsk city, as well as heat and electricity to industrial and agricultural enterprises in the region.[7]
Starting from 2016, the installed capacity of the Petropavlovsk-2 power station was 541 MW for electricity and 713 Gcal/h for heat.[6] According to 2016 annual report, the power station commissioned turbine unit No. 5 and boiler unit No. 12 that year. The new turbine unit has capacity of 95 MW.[8]
The power plant produced 2,703 million kWh of electricity in 2021, 3331 million kWh in 2020. Generation was 1,605 million kWh in 2022, 40% lower compared with 2021 level.[9]
In March 2026, Kazakhstan’s Ministry of Energy included Petropavlovsk-2 among ten thermal power plants that remained in the critical "red zone" and required urgent attention ahead of the next heating season.[10]
Modernization/Refurbishment
2016 Sevkazenergo report outlined the following modernization projects during 2013-2016:
2013: Reconstruction and modernization of a turbine unit No. 4 was completed with 30MW increase in capacity. Turbine unit No. 6 was upgraded with an increase in electric capacity by 24 MW. The implementation of two projects resulted in increase in the installed electric capacity by 54 MW.
2015: a turbine unit No. 1 was put into operation, which allowed increasing its installed electric capacity by 21 MW. Turbine unit No. 7 was reconstructed, which provided a possibility to increase its installed and available capacity by 24 MW.
2016: an upgraded turbine unit No. 5 was put into operation, as a result of which electric capacity increased by 62 MW. An upgraded boiler No. 12 was put into operation as a result of which steam capacity increased by 50 tons per hour.
The company reported in 2021 that as a result of its investments to modernize the generating equipment, the degree of wear and tear has reduced from 86% in 2009 to 55% in 2021.[11] 2023 power generation reached 2,308 million kWh.[12]
2024
At the end of 2024, the wear and tear of the main technical equipment, such as boiler units and generators, was 57.3%. In 2024, Petropavlovsk-2 power station underwent major overhauls of boilers No. 1, 3, 9 and 10, major overhauls of turbines No. 3, 6, and normal repairs of four turbines were completed. In addition, the construction of the 180-meter-high chimney No. 1 has been completed, and is scheduled to be commissioned at the end of 2025.[13][14] Additional works included completion of the project to raise the enclosing dams of ash disposal facility No. 2, replacement of network water heaters at boiler units Nos. 3 and 6, installation of an automated environmental emissions monitoring system at Chimney No. 3, and other auxiliary infrastructure upgrades.[15]
2025
In 2025, Petropavlovsk-2 power station reduced its air pollutant emissions to 28,000 tonnes, which was about 27% below the approved annual limit of slightly over 38,000 tonnes. The reduction was attributed to planned technical measures, including restoration of boiler heating surfaces, repairs of ash collection systems, and upgrades of gas ducts, as well as the operation of automated emissions monitoring systems installed at major emission sources.[16]
In June 2025, Sevkazenergo carried out a pilot industrial launch of the new 180-meter Chimney No. 1. The new stack was connected to the main gas duct serving boiler units Nos. 1-4, and that an automated emissions monitoring system had been installed as part of the project.[17]
In September 2025, Sevkazenergo stated that more than 26 billion tenge (approximately US$55.9 million) had been allocated for investment projects and repair works at Petropavlovsk-2 ahead of the 2025-2026 heating season. Capital repairs had been completed on boiler units Nos. 6 and 11 and turbine unit No. 2, while current repairs had been completed on boiler units Nos. 1, 4, 7, 8, 9, 10, and 12 and turbine units Nos. 3, 4, and 6. Capital repairs of turbine unit No. 7 and boiler unit No. 3 and current repair of boiler unit No. 5 were in the final stage.[18]
2026
In March 2026, Sevkazenergo stated that the number of technical incidents at Petropavlovsk-2 had declined from 88 in 2023 to 53 in 2025, a reduction of about 40%. In 2025, the company continued reconstruction of boiler unit No. 2 and turbine unit No. 1. The completion of boiler unit No. 2 was scheduled for 2027, while turbine unit No. 1 was scheduled to enter operation in 2026.[19] According to Sevkazenergo’s capacity disclosures, turbine unit No. 1 was listed as in reserve in December 2023 and June 2025, however by May 2026, Sevkazenergo listed turbine unit No. 1 as operating after reconstruction.[20][21]
As of March 2026, the 2026 repair plan for Petropavlovsk-2 included capital repairs of five boiler units and one turbine unit. At the time, boiler unit No. 6 was undergoing capital repair, including replacement of heating surfaces and repair of auxiliary equipment, while reconstruction of boiler unit No. 2 continued.[22]
In April 2026, public discussions were held for a working project to reconstruct Chimney No. 3 at Petropavlovsk-2.[23]
In May 2026, it was reported that Petropavlovsk-2 had installed automated environmental monitoring systems on each stack and at the water discharge point into the Esil River, with real-time data transmitted to regulators every 20 minutes. According to the North Kazakhstan regional ecology department, the plant’s emissions were 3.5 times below permitted limits.[24]
Incidents
There have been numerous incidents at the power station. For example, in January 2020, a boiler operator died after falling into burning ash while cleaning boiler slag.[25]
In March 2022, one of the three chimneys of the plant collapsed, resulting in one fatality. A crack was discovered in another chimney.[26] There is a plan to build a new chimney.[27] Construction of the new chimney commenced in spring 2023.[28] However later in 2023 a defect was discovered in the partially built new chimney and it will be demolished. Another new chimney is planned for construction in 2024.[29]
Coal Source
The power station's coal has been sourced from the Ekibastuz coal basin.[30]
