Osaki CoolGen Project is a 166 MW coal power station in Hiroshima, Japan. It ranks #207 of 692 Japan power plants by installed capacity. Commissioned in 2017, it is around 9 years old — relatively modern. Its modelled annual emissions are 2,117,900 t CO₂/yr (Climate TRACE), equivalent to about 494k cars driven for a year. In context, coal supplies about 32.1% of Japan's electricity; the national grid averages 477 gCO₂/kWh (32.7% low-carbon) (2025).

In context: how this plant compares
At 166 MW, Osaki CoolGen Project is below the median coal plant in Japan (250 MW). Technically it is described as subcritical. Its current lifecycle status is “Mothballed” — so it is not yet, or no longer, generating at full output. Coal plants burn pulverised coal to raise high-pressure steam for a turbine; they run as baseload but are the most carbon-intensive mainstream source and the first targeted for retirement or efficiency retrofits.
