Chiba

Gas power plant in Chiba, Japan. Approximate location 35.5648, 140.1053.

GasChibaJapanCO₂ reported

Chiba is a 2,880 MW gas power station in Chiba, Japan. It is operated by Tokyo. Based on its capacity (estimated), it can supply roughly 3,243,702 homes (estimated). It ranks #18 of 659 Japan power plants by installed capacity. Its measured emissions of 491,920 t CO₂/yr (Climate TRACE) are equivalent to about 114,667 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).

Local climate & thermal context

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 35.6°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 30% 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: 38/100 — 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 ~0% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).
