CoalEast JavaIndonesia

PLTU Gresik is a 600 MW coal power station in East Java, Indonesia. It is operated by PLN - Java Bali Generation Unit / PT. PJB. Based on its capacity (estimated), it can supply roughly 750,857 homes (estimated). It ranks #27 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).

~2,628,000 t CO₂/yr (estimated) — in everyday terms

This facility's annual emissions are roughly equivalent to:

612,587passenger cars driven for a year
342,723homes' yearly energy use
43,800,000tree seedlings grown 10 years to absorb it

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.

Local climate & thermal context

This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a tropical savanna climate (Köppen Aw) — Southern Hemisphere, latitude 7.2°S — which shapes how much energy it can produce and how its output varies through the year.

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.
