Project-level coal details
- Coal source(s): Ekibaztuz (Kazakhtstan)
Background
The plant is owned and operated by Wholesale Generating Company No. 2 (OGK-2), which is controlled by Gazprom.[1][2]
The nine original units of Troitskaya GRES coal-fired power plant, totalling 2,425 MW, were built in three stages between 1960 and 1976.
- Stage 1: Units 1-3: 3 x 85 MW (1960)
- Stage 2: Units 4-7: 4 x 300 MW (1965-67)
- Stage 3: Units 8-9: 2 x 485 MW (1974-76)
In 2008, OGK-2 began a modernization overhaul of the Troitskaya plant. Units 4, 5, 7, and 8 were modernized and equipped with modern pollution controls in 2008-2013.
As of November 2022, the operating capacity consisted of 2 Units from Stage 1 with 170MW and Unit 10 with 666MW commissioned in 2016 (see below on Retirement).[1] The plant's actual utilization has been very low in the recent years with capacity factor around 10% in 2019-2021.[3] The power plant produced 725 million kWh of electricity in 2021.[3] It was confirmed later in early 2023 that Units 1 and 3 from Stage 1 were retired in November 2022.[4]
Environmental Impact
Waste (ash and slag pulp) from the power station is dumped into lake Shubarkol in Kazakhstan. Two out of three sections of the lake are already full. Now the Russian company is faced with the task of cultivating the dumps, when the waste is covered with half a meter soil, sown with grass, and trees are planted.[5] In February 2022, there was a leak in the pipeline transporting waste to the lake.[6] After an inspection, the plant was brought to administrative responsibility under the article “Violation of environmental requirements for waste management operations”. The fine amounted to 459 thousand tenge ($1,000).[7]
Description of Expansion - 2016
A key aspect of OGK-2's modernization of the plant was to build two new 660-MW units, Units 10 and 11. The initial plan was to bring Unit 10 online in 2011, and Unit 11 in 2012.[8][9] In March 2009, construction was not yet underway and OGK-2 delayed the building of Unit 11 indefinitely. The completion date for Unit 10 was pushed back to 2013.[10] OGK-2 signed a construction contract with CJSC KVARZ in July 2010.[11] Construction was pushed back several times, but eventually Unit 10 was successfully tested in December 2015[12] and achieved final completion in June 2016 with 660MW capacity[13][14]
Retirement
Unit 9 with 485MW of capacity was shut down in early 2013.[2] The four 300 MW units constructed as part of stage 2 (Units 4-7) were decommissioned between 1992 and 2016.[15][1]
In October 2018 the Deputy Governor of Sergey Shal announced that the plant would be decommissioned and replaced by a new gas-fired boiler house to be built in the village of Energetikov by 2020.[16] In July 2019 construction was 95% complete on a boiler house that would enable Gazprom to retire Stage 1 of the power station (Units 1-3).[17] The gas pipeline to the boiler house was completed in January 2020.[18] In December 2020 it was reported that the station was still operating but would eventually be replaced by a new boiler house that would be tendered in 2021.[19]Unit 8 was decommissioned at the end of 2020.[20][21]
In December 2021, OGK-2 completed construction of a gas-fired boiler unit consisting of three hot water boilers and four steam boilers.[22] The company stated that this new unit would allow for the retirement of Stage 1 of the power station (Units 1-3 with 255MW of capacity).[23] In June 2022, it was reported that one of the nearby towns has almost finished construction of a boiler house to replace the power station once it stops the heat supply to this town.[24]
As of December 2021 and November 2022, 2 Units from Stage 1 are listed by OGK-2 as operating capacity, therefore one unit (presumably, Unit 2) has been recently retired.[1][3] The government decree from February 2022 states that Units 1 and 3 are to be retired by 2023.[25] This will leave Unit 10 (660 MW) as the only remaining coal-fired unit at the power station.
System Operator's document from February 2023 confirmed that Units 1 and 3 were retired in November 2022.[4]
