Vorkutinskaya-2 power station

From Global Energy Monitor

Vorkutinskaya-2 power station (Воркутинская ТЭЦ-2) is a 270-megawatt (MW) gas-fired power plant in Komi Republic, Russia. The power station was originally constructed to run on coal, but converted to gas in 2021.[1]

Background on Plant

The 270-MW Vorkutinskaya-2 power station is owned by Renova Group. The plant was constructed in three phases: Phase 1 began operating in 1955; Phase 2 was constructed between 1963 and 1967; and Phase 3 was constructed between 1973 and 1975.[2][3] Phase 1 consists of turbine units 1 & 2 with 35 MW and 28 MW of capacity, respectively; Phase 2 consists of turbine units 3, 4, and 5, with 25, 25, and 50 MW of capacity; and Phase 3 consists of turbine units 6 and 7, with capacity of 60 and 47 MW.[4] Unit 7 has capacity ranging from 47 to 55 MW, and is listed differently in different sources.[2][4] The 7 turbine units are powered by 9 boiler units, which originally ran on coal.[5] The station appears to use a cross-link system for flows of water and steam from the boilers to the turbines.

Coal-to-gas conversion

In February 2019 Renova's subsidiary T+ Group announced that the plant would be converted to gas.[6] In May 2019 Tass reported that the conversion would occur in 2020.[7] In February 2020 Gazprom completed a gas distribution point (GRP) at the plant and was building a gas pipeline branch and distribution station.[8] In September 2020 it was reported that the gas conversion would occur in 2021.[9] In May of 2021 reports state full gasification will be complete by September 2021.[10] In August 2021 the station's hot water boiler house was converted from coal to gas power.[11] The plant fully switched over to gas in December 2021. The gasification of the power station cost 1.2 billion rubles (approximately US$15.7 million).[1][12]
