Background

The power plant is owned by Inter Rao- Electric Power Generation, a subsidiary of Inter RAO. It used to be part of OGK-3 until 2012 when it was liquidated upon consolidation within Inter RAO.

The Cherepetskaya power station was approved by the Soviet Ministry of Power Plants in 1948, and the first four 140-MW units (burning brown coal) were completed in 1953-58. In 1963-66, the plant was expanded by additional two 300-MW and one 265-MW units (burning lignite coal).[3]

Two additional 225-MW coal-fired units, Units 8 and 9, were built by Inter RAO, at a cost of approximately $800 million.[4] Unit 8 was completed in December 2014.[5] Unit 9 was successfully tested in April 2015, and was completed in June 2015.[6][7] The plant's capacity reached 1875 MW.

In February 2016 it was reported that declining energy prices would force Inter Rao to retire 865 MW of the plant's capacity in 2019: the two 300-MW units and one 265-MW unit.[8] A different report from February 2016 was that Inter Rao would retire a total of 1,285 MW at the plant, meaning that three of its original 140-MW units would also be retired.[9] It appears that another fourth 140-MW unit was already retired earlier.[10]

As of December 2019 the Inter Rao website and Glavgosexpertiza, the Russian Ministry of Construction, listed only Unit 8 and Unit 9 as operational, meaning that Units 1-7 have been retired.[11][12] Inter RAO's website states that old inefficient equipment was retired as of January 2017, leaving installed capacity at 450MW.[13]

A May 2019 audit of the plant found that personnel were inadequately trained and that the plant's equipment was becoming increasingly unreliable.[14]

The plant's electricity generation reached 1,641 million kWh in 2021 and 1,486 million kWh in 2020.[15]

Coal to Gas Conversion

In November 2020 Inter RAO announced plans to convert Unit 8 and Unit 9 to run on gas by 2026.[16] In September 2021, natural gas began to be supplied to the power station for the needs of the start-up and heating of the boiler house: three of the boilers with operating capacity 30-35 MW each started operating on gas.[17] This was the first step in the conversion of the power station to gas.[17]

In October 2021, Glavgosexpertisa of the Russian Federation (government review department) issued a positive conclusion on re-designed documentation for the construction of gas supply facilities for power units at the power station. A number of adjustments were made to the project. It was related to the conversion of the boiler units 8 and 9 with capacity of 30 MW to run on natural gas.[18] Existing coal-fired boiler units were expected to be modified and switched to run on gas.[19]

A media source from February 2023 reported that Inter Rao is working on a mechanism to finance the conversion of the units to gas as this would require change in the legislation. Due to high coal prices, the station has been operating with losses for 2 years. No timeframe was mentioned.[20] The conversion of requires the construction of a gas pipeline and direct work at power units. According to independent analyst Yuri Melnikov, the company will have to completely reconstruct the boilers, build a gas infrastructure inside the station and two independent main gas pipelines.[20] As of December 2023, there was no news on this initiative. The project was not mentioned in the Russian Ministry of Energy 2024-2029 energy program released in November 2023.[21]

Combined cycle proposal

Another proposal was mentioned in November 2020 which includes construction of two combined cycle units 300 MW each.[16] These CC units would potentially be built via addition of turbines/equipment to existing gas turbines 8 and 9.[16] It was reported that although president Putin supported the project, it has not been approved by the Ministry of Energy since there is no expected electricity generation deficit in the region that would necessitate addition of these units.[16] Since November 2020, there have not been any developments related to this proposal and as of November 2022, it is considered shelved.[16] A media source from February 2023 mentioned that this is not pursued.[20] The project was not included in the Russian Ministry of Energy 2024-2029 energy program released in November 2023.[21]
