Krasnoyarskaya GRES-2

Krasnoyarskaya GRES-2 (KGRES-2)

Krasnoyarskaya GRES-2 is located in Zelenogorsk 167 km to the east of Krasnoyarsk. The installed capacity of the plant is 1,250 MW.

The primary fuel is brown coal from the Irsha-Borodinsky coal strip mine of the Kansko-Achinsky coal basin, 2BR-grade. There is no reserve fuel and the starting fuel is fuel oil.

The competitive environment includes HPPs of the Angaro-Eniseisky Cascade (regulation and base capacity), efficient thermal generation by the Nazarovskaya GRES (500 MW unit), Berezovskaya GRES and the plants of the former Kuzbassenergo. The plant’s load in many ways depends on seasonal factors such as the level of water in the reservoirs and the air temperature. In 2009 after the accident at Sayano-Shushenskaya HPP, the generation of Krasnoyarskaya GRES-2 demonstrated persistent growth due to capacity constraints arising at Siberian UPS.

Capacity limitations

Krasnoyarskaya GRES-2 has a seasonal capacity limitation from 15 to 30 MW.

- from January to May – 20 MW (1.6% of the installed capacity);

- from June to August – 30 MW (2.4% of the installed capacity);

- September – 16 MW (1.2% of the installed capacity);

- from October to December – 21 MW (1.7% of the installed capacity);

The limitations are because of the insufficient thermal load of PT type turbines at plants 9 and 10 (due to the lack of a steam consumer and a design peculiarity of the operated units.)

The installed electric capacity is 1,250 MW

The installed heat capacity is 1,176 Gcal/h
