PLTGU Muara Karang Block I is a 509 MW gas power station in Jakarta Raya, Indonesia. It is operated by PLN – Java Bali Generation Unit / PT. PJB. Based on its capacity (estimated), it can supply roughly 573,279 homes (estimated). It ranks #28 of 178 Indonesia power plants by installed capacity. In context, gas supplies about 18.5% 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 45% load factor × a typical gas emission factor (~400 g CO₂/kWh, IPCC AR5 / US EIA). Actual emissions depend on plant efficiency and running hours.Equivalencies via US EPA Greenhouse Gas Equivalencies.

This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a tropical rainforest climate (Köppen Af) — Southern Hemisphere, latitude 6.1°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.
A gas turbine here also runs ~9% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).

The #8 largest gas power plant of 41 in Indonesia by capacity.
Indonesia has 41 gas power plants in this dataset, together about 12,810 MW of capacity.
