Tobata is a 892 MW gas power station in Fukuoka, Japan. It is operated by TOBATA COOP THERMAL POWER CO. Based on its capacity (estimated), it can supply roughly 1,004,421 homes (estimated). It ranks #99 of 659 Japan power plants by installed capacity. Its measured emissions of 2,744,200 t CO₂/yr (Climate TRACE) are equivalent to about 639,674 cars driven for a year. In context, gas supplies about 32.8% of Japan's electricity; the national grid averages 477 gCO₂/kWh (32.7% low-carbon) (2025).

This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 33.9°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 36% 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: 35/100 — 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.
A gas turbine here also runs ~1% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).

The #28 largest gas power plant of 49 in Japan by capacity.
Japan has 49 gas power plants in this dataset, together about 65,031 MW of capacity.
