Sumsel-5 power station is a 650 MW coal power station in South Sumatra, Indonesia. It is operated by PT DSSP Power Sumsel [100%]. Based on its capacity (estimated), it can supply roughly 813k homes (estimated). It ranks #63 of 401 Indonesia power plants by installed capacity. Commissioned in 2016, it is around 10 years old — relatively modern. In context, coal supplies about 61.5% of Indonesia's electricity; the national grid averages 680 gCO₂/kWh (18.1% low-carbon) (2024).

The public capacity above is the current source-record value. A 2026 tracker candidate lists 300 MW for Sumsel-5 power station, but it is not used as the public primary value until scope is verified (unit vs operating vs installed/project total).
The capacity and fuel fields on this page are source-record values from the upstream open dataset. They are useful for identification and ranking, but they have not been upgraded to a 2026 registry/GEM-location verified value.

At 650 MW, Sumsel-5 power station is well above the median coal plant in Indonesia (220 MW). Technically it is described as subcritical. Coal plants burn pulverised coal to raise high-pressure steam for a turbine; they run as baseload but are the most carbon-intensive mainstream source and the first targeted for retirement or efficiency retrofits.

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 2.2°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).
For a plant’s outdoor hardware — heat-recovery steam generators (HRSG), expansion joints, valves, flanges and their insulation — the local climate sets how fast unprotected steel and coatings degrade. This site sits in a corrosive environment (estimated ISO 9223 class C4 — High), with humidity / wetness the leading environmental stress.
Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.
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.
The #41 largest coal power plant of 191 in Indonesia by capacity.
Indonesia has 191 coal power plants in this dataset, together about 101,995 MW of capacity.
