The Sixth Wholesale Power Market Generating Company JSC (OGK-6) was established in 2006 through the consolidation of six thermal power plants in Russia:
- Novocherkassk GRES – 2,112 MW
- Kirishi GRES – 2,100 MW
- Ryazan GRES – 2,650 MW
- Krasnoyarsk-2 GRES – 1,250 MW
- Cherepovets GRES – 1,050 MW
- GRES-24 – 310 MW (located in Novomichurinsk; integrated into Ryazan GRES in 2008)
Together, these facilities provided an aggregate installed capacity near 9,052 MW, positioning OGK-6 as the fourth largest power producer in Russia by capacity. The combined thermal output of these plants reached 2,704 Gcal/h, and in 2007 the company produced around 32.065 TWh of electrical energy.
Shares of OGK-6 were listed on both the MICEX and RTS stock markets.
In April 2010, Gazprom—holding significant stakes in OGK-2 and OGK-6—revealed intentions to merge OGK-6 into OGK-2. This consolidation resulted in a single entity managing ten power stations with a total capacity of approximately 17,750 MW. The merger was completed on 1 November 2011.
