OilAkitaJapan

Akita is a 1,300 MW oil power station in Akita, Japan. It is operated by Tohoku. Based on its capacity (estimated), it can supply roughly 976,114 homes (estimated). It ranks #55 of 659 Japan power plants by installed capacity. In context, oil supplies about 2.5% of Japan's electricity; the national grid averages 477 gCO₂/kWh (32.7% low-carbon) (2025).

~2,562,300 t CO₂/yr (estimated) — in everyday terms

This facility's annual emissions are roughly equivalent to:

597,273passenger cars driven for a year
334,155homes' yearly energy use
42,705,000tree seedlings grown 10 years to absorb it

Estimated, not measured: from installed capacity at a typical 30% load factor × a typical oil emission factor (~750 g CO₂/kWh, IPCC AR5 / US EIA). Actual emissions depend on plant efficiency and running hours.Equivalencies via US EPA Greenhouse Gas Equivalencies.

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 39.8°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 16% 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: 59/100 — 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.
