CHP-21 Gas Power Plant, Moscow, Russia | 1,800 MW Combined Heat and Power

CHP-21 is a gas-fired combined heat and power (CHP) plant located in Moscow, Russia, with a capacity of 1,800 MW. It is owned and operated by PJSC Mosenergo, a major energy company in the region. The plant plays a key role in the Moscow energy system, providing both electricity and district heating. As a gas-fired facility, CHP-21 operates with lower CO2 and pollutant emissions compared to coal-fired plants. The plant's technology is typical for modern Russian CHP plants, often using combined-cycle gas turbine (CCGT) units for high efficiency. Russia's power generation sector is regulated by federal laws on electric power and environmental protection, with emission standards aligned to national targets. CHP-21 is strategically important for Moscow's energy security, supplying heat to residential and industrial consumers. Its location in a densely populated urban area necessitates strict adherence to environmental regulations. The plant contributes to the stability of the Moscow power grid and supports the city's growing energy demand.

CHP-21's gas-fired operation results in lower emissions of sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter compared to coal-fired plants. However, its location in a densely populated urban area requires careful management of local air quality. The plant's high capacity and combined heat and power configuration improve overall energy efficiency, reducing fuel consumption and associated greenhouse gas emissions per unit of output.
