Sakaide is a 1,500 MW oil power station in Kagawa, Japan. It is operated by Shikoku. Based on its capacity (estimated), it can supply roughly 1,126,285 homes (estimated). It ranks #49 of 659 Japan power plants by installed capacity. Its measured emissions of 1,951,300 t CO₂/yr (Climate TRACE) are equivalent to about 454,848 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).

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 34.3°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 26% 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: 40/100 — 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.

The #10 largest oil power plant of 37 in Japan by capacity.
Japan has 37 oil power plants in this dataset, together about 45,972 MW of capacity.
