Background on Plant

Ryazanskaya GRES power station is a 3,070-MW power plant in Novomichurinsk, a company town for the plant. Ryazanskaya's primary fuelstocks are lignite coal and natural gas, with fuel oil as a backup; the plant's first four units, totaling 1,230 MW current capacity, run on lignite coal, and the two 800-MW Units 5 and 6 and 420-MW Unit 7 run on natural gas (Units 5 and 6 were converted from coal in 1984). The first four units were built in 1973-74, Units 5 and 6 in 1974-81, and Unit 7 in 2010. The plant is currently owned by the Wholesale Generation Company No. 2 of the Electricity Market (OGK-2), which is majority-owned by Gazprom (it was previously owned by OGK-6, which was consolidated with OGK-2 in 2011).[1][2][3]

In March 2018 Ryazan Governor Nikolai Lyubimov announced that half of the plant's units would be retired in 2021, specifically the units that provide heat to Novomichurinsk.[4]

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 a seventh 330-MW coal-fired unit at Ryazanskaya, with a completion date of 2010.[5] After the restructuring, OGK-6 apparently decided to build a gas-fired unit instead: the construction on the 330-MW, gas-fired Unit 7 (also referred to as Ryazanskaya GRES-24) began in 2008, and the unit was brought online in 2010. There is no mention of a future coal-fired unit at Ryazanskaya in OGK-2's 2011 annual report.[6][7]

Unit 2 of the plant was apparently retrofitted, with completion in 2014; it is possible that sources have mistaken this retrofitting for a new coal-fired unit.
