Higashi-Dori — Japan

Higashi-Dori is a 1,100 MW nuclear power station in Aomori, Japan. It ranks #91 of 692 Japan power plants by installed capacity. Commissioned in 2005, it is around 21 years old — relatively modern. 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 1,100 MW, Higashi-Dori 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.
