Ryazanskaya GRES power station

From Global Energy Monitor

Ryazanskaya GRES power station (Ryazan SDPP power station, Рязанская ГРЭС), also known as Novomichurinsk GRES (Новомичуринская ГРЭС), is a 3,024-megawatt (MW) power plant (1,114 MW coal-fired and 1,920MW gas-fired) in Ryazan province, Russia.

Background on Plant

The plant is 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]

Ryazanskaya GRES power station is a 3,024-MW power plant in Novomichurinsk. Ryazanskaya's primary fuel stocks are lignite coal and natural gas, with fuel oil as a backup. The plant's first four units 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).

In 2021, coal accounted for 62% of the plant's fuel balance.[4] Coal for the power station is sourced from the Kansk-Achinsk coal basin and the Moscow Region coal basin.[5] The power plant produced 3,403 million kWh of electricity in 2021 and 1,516 million kWh in 2020.[4]

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.[6] As of November 2022, there have been no updates on retiring units at Ryazanskaya GRES power station since 2018; the status of the retirement plan is unclear.

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.[7] 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.[8][9]

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.


In 2021, the Ryazanskaya GRES power station was named as one of the main polluters of the Ryazan region.[10]
