CHP-21 is a 1,765 MW gas power station in Moscow, Russia. It is operated by PJSC "Mosenergo". Based on its capacity (estimated), it can supply roughly 2.0 million homes (estimated). It ranks #47 of 678 Russia power plants by installed capacity. Commissioned in 1963, it is around 63 years old — an older, legacy facility. In context, gas supplies about 44.7% of Russia's electricity; the national grid averages 450 gCO₂/kWh (35.7% low-carbon) (2025).

At 1,765 MW, CHP-21 is well above the median gas plant in Russia (200 MW). Technically it is described as CCGT; combined-cycle with a heat-recovery steam generator (HRSG). Gas plants burn natural gas either in open-cycle turbines for fast peaking, or in combined-cycle units that recover exhaust heat in an HRSG to reach roughly 55–62% efficiency — the cleanest-burning fossil option.

This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a warm-summer humid continental climate (Köppen Dfb) — Northern Hemisphere, latitude 55.9°N — which shapes how much energy it can produce and how its output varies through the year.
