Cherepetskaya power station

From Global Energy Monitor

Cherepetskaya power station is a 450-megawatt (MW) coal-fired power plant in Tula province, Russia.

As of November 2020, the station was proposed to be converted to gas by 2026 with expected generating capacity of 600 MW.[1]

Background on Plant

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 an additional two 300-MW and one 265-MW units (burning black coal).[2] The plant is owned by Russia's Inter RAO.[3]

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.[4] 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.[5] 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.[6][7]

A May 2019 audit of the plant found that personnel were inadequately trained and that the plant's equipment was becoming increasingly unreliable.[8]

Description of Expansion

The RAO UES 2006-10 five-year plan (from before the restructuring of RAO UES), which RAO management approved in January 2007, lists as a long-term project the addition of two 225-MW coal-fired units at Cherepetskaya, with a completion date of 2010.[9] These two additional 225-MW coal-fired units, Units 8 and 9, are being built by Inter RAO, at a cost of approximately $800 million.

In 2010, state and local permits were issued, and the company poured foundations for the two units.[10] The two units' electric alternators were completed in January 2013. Completion of Unit 8 is scheduled for the first quarter of 2014, and Unit 9 in the fourth quarter of 2014.[11][12]

Unit 8 was completed in December 2014.[13] Unit 9 was successfully tested in April 2015, and was completed in June 2015.[14][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.[1] In September 2021, natural gas began to be supplied to the power station for the needs of the start-up and heating boiler house: three of the boilers with operating capacity 30-35 MW each started operating on gas.[16] Gas will be used not only to provide hot water supply to consumers in the city of Suvorov, but will also be used to kindle and illuminate generating equipment. This is announced to be one of the first steps in the conversion of the power station to gas.[16]

In October 2021, Glavgosexpertisa of the Russian Federation (government review department) issued a positive conclusion on re-design documentation for the construction of gas supply facilities for power units at the power station. A number of adjustments were made to the project. This is related to the conversion of the boiler/turbine units 8 and 9 with capacity of 30 MW to run on natural gas.[17]

Another proposal was mentioned in November 2020 which includes construction of two combined cycle units 300 MW each.[1] Since November 2020, there have not been any updates related to this proposal.[1]
