Kirishskaya GRES
Kirishskaya GRES (KiGRES)
Kirishskaya GRES is located in Kirishi, 150 km to the southeast of St. Petersburg. The installed capacity of the plant is 2,100 MW.
When the plant was under construction the designed type of fuel was fuel oil. Subsequently, generation units 1-6 of the condensation section of the plant and boilers K1T-6T of the heat-extraction section were converted to natural gas firing. Currently natural gas is used as the primary fuel for the plant. Reserve fuel is M-100-grade fuel oil supplied by Kirishi refinery (LLC KINEF). Starting fuel is gas and fuel oil.
The plant is a part of Northwest UPS, the generating capacity of which is also comprised of Leningradskaya NPP, Pskovskaya GRES (OGK-2), HPP and CHPP TGK-1 and Northwestern CHPP. Apart from Kirishskaya GRES, only approximately 400 MW of HPP TGK-1, condensate production of CHPP 22 (South) and CHPP 21 (North) as well as reversible flow from Karelenergo (at 330 kW voltage) and Central UPS, may be attributed to the regulating sources of the central part of the UPS. The aggregate regulation capacity of these sources in the winter period is less than the capacity of Kirishskaya GRES and does not meet the needs of the central part of the UPS for regulation which makes the plant the key frequency and capacity regulator in the system. Kirishskaya GRES units operating in the load following mode are the primary source of power for the balancing market in the region. The system operator assigns a fairly high load to the plant using it as a regulator to ensure system reliability.
Capacity limitations
Kirishskaya GRES has some limitations of a seasonal nature:
- from December to March – 300 MW (14.3% of the installed capacity);
- from July to August – 600 MW (28.6%).
This is due to the presence of whitefish species in the Volkhov River which imposes some limitations on the temperature of water discharged by the plant.
The installed electric capacity is 2,100 MW
The installed heat capacity is 1,234 Gcal/h
