PLTU Cilacap 1 & 2 is a 600 MW coal power station in Central Java, Indonesia. It is operated by PT. Sumber Segara Primadaya. Based on its capacity (estimated), it can supply roughly 750,857 homes (estimated). It ranks #26 of 178 Indonesia power plants by installed capacity. In context, coal supplies about 61.5% of Indonesia's electricity; the national grid averages 680 gCO₂/kWh (18.1% low-carbon) (2024).

This facility's annual emissions are roughly equivalent to:
Estimated, not measured: from installed capacity at a typical 50% load factor × a typical coal emission factor (~1000 g CO₂/kWh, IPCC AR5 / US EIA). Actual emissions depend on plant efficiency and running hours.Equivalencies via US EPA Greenhouse Gas Equivalencies.

This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a tropical rainforest climate (Köppen Af) — Southern Hemisphere, latitude 7.8°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.

The #17 largest coal power plant of 70 in Indonesia by capacity.
Indonesia has 70 coal power plants in this dataset, together about 29,333 MW of capacity.
