Smolensk is a 3,000 MW nuclear power station in Smolensk, Russia. It is operated by JSC "Concern Rosenergoatom". Based on its capacity (estimated), it can supply roughly 6.8 million homes (estimated). It ranks #21 of 678 Russia power plants by installed capacity. Commissioned in 1983, it is around 43 years old — long-established. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, nuclear supplies about 18.3% of Russia's electricity; the national grid averages 450 gCO₂/kWh (35.7% low-carbon) (2025).

At 3,000 MW, Smolensk is well above the median nuclear plant in Russia (2,400 MW). Technically it is described as light water graphite reactor. Nuclear plants split uranium to raise steam with no direct CO₂; they run as steady baseload with very high capacity factors and the longest operating lifetimes of any thermal plant.

This nuclear plant uses heat from nuclear fission to raise steam for a turbine-generator. It sits in a warm-summer humid continental climate (Köppen Dfb) — Northern Hemisphere, latitude 54.2°N — which shapes how much energy it can produce and how its output varies through the year.
