Kin power station

Coal power plant in Okinawa, Japan. Approximate location 26.446, 127.9214.

CoalOkinawaJapanCO₂ reported

Kin power station is a 440 MW coal power station in Okinawa, Japan. It is operated by Okinawa Electric Power Co. Based on its capacity (estimated), it can supply roughly 550,628 homes (estimated). It ranks #137 of 659 Japan power plants by installed capacity. Commissioned in 2002, it is around 24 years old — relatively modern. Its measured emissions of 2,446,000 t CO₂/yr (Climate TRACE) are equivalent to about 570,163 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).

Local climate & thermal context

This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 26.4°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 97% below the median power plant in this dataset — a proxy for how much extra energy heated equipment must replace through its surfaces in winter.

Climate heat-demand index: 14/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.

In colder climates, uninsulated hot equipment (boilers, turbines, valves, steam lines) loses proportionally more heat to ambient air — exactly the loss Inzonex modular insulation is designed to cut.
