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).

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.
