Smolenskaya GRES is a 630 MW gas power station in Smolensk, Russia. It is operated by PJSC "Unipro". Based on its capacity (estimated), it can supply roughly 710k homes (estimated). It ranks #122 of 678 Russia power plants by installed capacity. Commissioned in 1970, it is around 56 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 630 MW, Smolenskaya GRES 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.

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 55.6°N — which shapes how much energy it can produce and how its output varies through the year.
