The First Generation Company of the Wholesale Electricity Market (OGK-1) is a large Russian company formed by the merger of six electricity generation companies.


The company was established in 2005 by merging six power plants into one company. Before 1 July 2008, about 92% of the company's shares was owned by RAO UES, Russian state-controlled energy holding company. As a result of the electricity market reform, 43% of shares was transferred to the Federal Grid Company of Russia, 23% to RusHydro, and 34% was distributed to minority shareholders.

On March 17, 2009 the rights under 61,9% of voting shares were transferred to Inter RAO UES for 5 years with the right for extension for the same period. Starting from July 6, 2009 the powers of the sole executive body of OGK-1 were transferred to Inter RAO UES.[1]


OGK-1 operates following power stations:

  • Permskaya GRES – 2,400 MW,
  • Nizhnevartovskaya GRES – 1,600 MW
  • Iriklinskaya GRES – 2,430 MW
  • Kashirskaya GRES - 1,580 MW
  • Verkhne-Tagilskaya GRES – 1,497 MW
  • Urengoyskaya GRES - 24 MW.

The installed capacity of these power stations is about 9,500 MW. This comprises about 5.5% of the generating capacity of RAO UES.

The power output of the OGK-1 power plants in 2006 was around 48 TW.
