Shika — Japan

Shika is a 1,746 MW nuclear power station in Ishikawa, Japan. It ranks #50 of 692 Japan power plants by installed capacity. Commissioned in 1993, it is around 33 years old — long-established. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, nuclear supplies about 9.1% of Japan's electricity; the national grid averages 477 gCO₂/kWh (32.7% low-carbon) (2025).

In context: how this plant compares

At 1,746 MW, Shika is below the median nuclear plant in Japan (2,070 MW). Technically it is described as boiling water reactor. Its current lifecycle status is “Mothballed” — 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.
