Hachinohe Taiheiyo

Oil power plant in Aomori, Japan. Approximate location 40.5353, 141.5019.

OilAomoriJapanCO₂ reported

Hachinohe Taiheiyo is a 125 MW oil power station in Aomori, Japan. It is operated by TAIHEIYO (PACIFIC) METALS. Based on its capacity (estimated), it can supply roughly 94,007 homes (estimated). It ranks #199 of 659 Japan power plants by installed capacity. Its measured emissions of 69,097 t CO₂/yr (Climate TRACE) are equivalent to about 16,107 cars driven for a year. In context, oil supplies about 2.5% of Japan's electricity; the national grid averages 477 gCO₂/kWh (32.7% low-carbon) (2025).

Local climate & thermal context

This oil plant burns oil or diesel to drive turbines or reciprocating engines. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 40.5°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 42% 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: 75/100 — 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.
