Haramachi power station

Coal power plant in Fukushima, Japan. Approximate location 37.666, 141.0165.

CoalFukushimaJapanCO₂ reported

Haramachi power station is a 2,000 MW coal power station in Fukushima, Japan. It is operated by Tohoku Electric Power Co. Based on its capacity (estimated), it can supply roughly 2,502,857 homes (estimated). It ranks #25 of 659 Japan power plants by installed capacity. Commissioned in 1998, it is around 28 years old — long-established. Its measured emissions of 11,118,700 t CO₂/yr (Climate TRACE) are equivalent to about 2,591,772 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 37.7°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 7% 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: 47/100 — this site sits in the mid 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.
