Handa (Summit) power station is a 75 MW biomass power plant in Aichi, Japan. It is operated by Summit Handa Power Co Ltd. Based on its capacity (estimated), it can supply roughly 103,242 homes (estimated). It ranks #237 of 659 Japan power plants by installed capacity. In context, biomass supplies about 5.3% of Japan's electricity; the national grid averages 477 gCO₂/kWh (32.7% low-carbon) (2025).

This biomass plant burns organic material (wood, residues) to raise steam for a turbine. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 34.9°N — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
Heating degree-days here run 27% 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: 39/100 — 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.
