Tokuyama Central power station is a 372 MW other power station in Yamaguchi, Japan. It is operated by Tokuyama Corp. Based on its capacity (estimated), it can supply roughly 279,318 homes (estimated). It ranks #143 of 659 Japan power plants by installed capacity. Its measured emissions of 2,068,000 t CO₂/yr (Climate TRACE) are equivalent to about 482,051 cars driven for a year. In context, the national grid averages 477 gCO₂/kWh (32.7% low-carbon) (2025).

This other plant generates electricity for the grid. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 34.1°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 29% 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: 39/100 — 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 other power plant of 35 in Japan by capacity.
Japan has 35 other power plants in this dataset, together about 10,650 MW of capacity.
