WindAomoriJapan

Mutsu-Ogawara is a 32 MW wind power plant in Aomori, Japan. It is operated by ECOPOWER CO LTD. Based on its capacity (estimated), it can supply roughly 27,231 homes (estimated). It ranks #337 of 659 Japan power plants by installed capacity. Commissioned in 2003, it is around 23 years old — relatively modern. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, wind supplies about 1.2% of Japan's electricity; the national grid averages 477 gCO₂/kWh (32.7% low-carbon) (2025).

Local climate & thermal context

This wind plant converts the kinetic energy of wind into electricity through turbine rotors. It sits in a warm-summer humid continental climate (Köppen Dfb) — Northern Hemisphere, latitude 41.0°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 33% above 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: 70/100 — this site sits in the top 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.
