CHP is an abbreviation for Combined Heat and Power. It is a technology that produces electricity and thermal energy at high efficiencies. Coal units track this information in the Captive Use section when known.

Background

The government decision on the complex construction of the Iriklinskaya GRES was made on June 8, 1962. In November 1970, the first unit with a capacity of 300 MW was put into operation. In December of the same year, the second power unit was launched. After commissioning of the remaining four power units in 1971-1974 the first stage of the GRES with a capacity of 1800 MW was put into permanent operation in 1975. In December 1978, power unit No. 7 was put into operation, and on November 17, 1979, with the launch of the eighth power unit, the expansion of the GRES was completed.

Iriklinskaya GRES is the most powerful power plant in the South Urals. The structure of the plant includes 26 divisions, including 8 power units with a total capacity of 2,452.5 MW (including a hydroelectric power plant with a capacity of 22.5 MW). Seven power units have a capacity of 300 MW each, one of the units (station No. 2) increased its capacity to 330 MW after modernization.

Under the modernization program, unit 4 is to be replaced in 2023 with a 330 MW unit (4R). Units 1 and 3 with the same type of the steam turbine are also in the modernization program: unit 1 is to be upgraded in 2027 to 330 MW and unit 3 is to be upgraded in 2026 to 330 MW. As of November 2022, it is unclear whether units 1 and 3 are to be replaced similar to unit 4, or simply upgraded without a turbine replacement.

According to the document "Schemes and Programs for Development of Power Systems of Russia for 2023-2028" issued by the Ministry of Energy in February 2023, units 1 and 3 will be upgraded in 2027 and 2026, accordingly, and Unit 4 will be replaced in 2024. In March 2023, it was reported, the replacement of Unit 4 had begun and was expected to completed by March 2024. Units 1 and 3 will be upgraded as well. All equipment for the modernization was manufactured in Russia: by the Leningrad Metal Plant and the Electrosila Plant (both part of JSC "Power Machines").

Unit 4R was launched in March 2024, modernization of units 1 and 3 is ongoing.
