Location
The undated satellite photo below shows the plant, which is near Troitsk city, Troitsky district, Chelyabinsk province. The plant is located less than a kilometer from the Kazakh border. The new Unit 10 can be seen on the right.
Background on Plant
The nine original units of Troitskaya GRES coal-fired power plant, totaling 2,425 MW, were built in three stages between 1960 and 1976. The plant is currently owned and operated by Wholesale Generating Company No. 2 (OGK-2), which is controlled by Gazprom.[1][2]
- 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. Unit 6 was dismantled.[3][4] Unit 9 was shut down in early 2013, and part of the plant's workforce was laid off; with this, the plant's nameplate capacity was technically reduced to 1,574 MW.[5]
The plant has historically been relatively efficient, and thus its power is in very high demand; however, in 2011, the plant experienced substantial production problems, falling to a capacity-utilization rate of only 24% in that year.[6]
Description of Expansion
A key aspect of OGK-2's modernization of the plant was the plan to build two new 660-MW coal-fired units, Units 10 and 11, at the site. The initial plan was to bring Unit 10 online in 2011, and Unit 11 in 2012.[6][7]
In March 2009, with construction on the project not yet underway, OGK-2 delayed the building of Unit 11 indefinitely, as part of an overall reduction in the company's future development plans. The completion date for Unit 10 was pushed back to 2013.[8]
OGK-2 signed a construction contract with CJSC KVARZ in July 2010. The construction contract was issued in December 2010.[9] Work on the 240-meter stack began in December 2011.[10] Construction was originally slated to be completed in November 2014.[6] As of November 2014, completion had been pushed back to 2015.[11]
Unit 10 was successfully tested in December 2015.[12] The unit was completed in June 2016.[13]
Planned retirement
In October 2018 the Deputy Governor of Sergey Shal announced that the plant would be decommissioned and replaced by a new gas-fired plant that would be built in the village of Energetikov by 2020.[14]
