Sumsel-1 power station is a 700 MW coal power station in South Sumatra, Indonesia. It is operated by China Shenhua Energy Co Ltd; PT Lion Power Energy. Based on its capacity (estimated), it can supply roughly 876k homes (estimated). It ranks #57 of 401 Indonesia power plants by installed capacity. Commissioned in 2025, it is around 1 years old — recently built. In context, coal supplies about 61.5% of Indonesia's electricity; the national grid averages 680 gCO₂/kWh (18.1% low-carbon) (2024).

In context: how this plant compares
At 700 MW, Sumsel-1 power station is well above the median coal plant in Indonesia (220 MW). Technically it is described as supercritical. 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.
Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Climate zone & how it works
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 3.5°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 a corrosive environment (estimated ISO 9223 class C4 — High), with humidity / wetness 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 #35 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.
