Smolenskaya CHPP-2 is a 295 MW gas power station in Smolensk, Russia. It is operated by PJSC "Quadra - Power Generation". Based on its capacity (estimated), it can supply roughly 332k homes (estimated). It ranks #257 of 678 Russia power plants by installed capacity. Commissioned in 1973, it is around 53 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).

In context: how this plant compares
At 295 MW, Smolenskaya CHPP-2 is well above the median gas plant in Russia (200 MW). Technically it is described as Steam. 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.
Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Climate zone & how it works
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 54.8°N — which shapes how much energy it can produce and how its output varies through the year.
Climate zone & typical temperatures: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).
Site climate & environmental severity
This site sits in a mild atmospheric environment (estimated ISO 9223 class C2 — Low), with humidity / wetness the leading environmental stress.
Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
