Kamojang 1 2 3 is a 140 MW geothermal power station in West Java, Indonesia. It is operated by PLN – Indonesia Power. Based on its capacity (estimated), it can supply roughly 262,800 homes (estimated). It ranks #75 of 178 Indonesia power plants by installed capacity. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, geothermal supplies about 4.5% of Indonesia's electricity; the national grid averages 680 gCO₂/kWh (18.1% low-carbon) (2024).

This geothermal plant taps underground heat to raise steam that drives a turbine. It sits in a tropical rainforest climate (Köppen Af) — Southern Hemisphere, latitude 6.4°S — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
Heating degree-days here run 100% 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: 13/100 — this site sits in the bottom 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.
