In context: how this plant compares

At 1,860 MW, Zarnowiec Original nuclear power plant is well above the median nuclear plant in Poland (1,200 MW). Technically it is described as pressurized water reactor. Its current lifecycle status is “Cancelled” — so it is not yet, or no longer, generating at full output. 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.
