Kaltim power station is a 280 MW gas power station in East Kalimantan, Indonesia. It is operated by PT PLN (Persero) [100%]. Based on its capacity (estimated), it can supply roughly 315k homes (estimated). It ranks #138 of 401 Indonesia power plants by installed capacity. Commissioned in 2013, it is around 13 years old — relatively modern. In context, gas supplies about 18.5% of Indonesia's electricity; the national grid averages 680 gCO₂/kWh (18.1% low-carbon) (2024).

Capacity provenance
The public capacity above is the current source-record value. A 2026 tracker candidate lists 100 MW for Kaltim power station, but it is not used as the public primary value until scope is verified (unit vs operating vs installed/project total).
Data provenance
Capacity and fuel are the upstream open-dataset record, not yet matched to a 2026 registry or GEM entry.

In context: how this plant compares
At 280 MW, Kaltim power station is well above the median gas plant in Indonesia (150 MW). Technically it is described as CCGT; combined-cycle with a heat-recovery steam generator (HRSG). Gas plants burn natural gas either in open-cycle turbines for fast peaking, or in combined-cycle units that recover exhaust heat in an HRSG to reach roughly 55–62% efficiency — the cleanest-burning fossil option.
Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Climate zone & how it works
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 0.4°S — which shapes how much energy it can produce and how its output varies through the year.
Climate zone & typical temperatures: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).
Site climate & environmental severity
This site sits in an aggressive, high-corrosion environment (estimated ISO 9223 class C5 — Very high), with marine salt corrosion the leading environmental stress.
Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
How it compares & nearby plants
The #47 largest gas power plant of 138 in Indonesia by capacity.
Indonesia has 138 gas power plants in this dataset, together about 44,657 MW of capacity.
