Celukan Bawang power station is a 426 MW coal power station in Bali, Indonesia. It is operated by PT General Energy Bali. Based on its capacity (estimated), it can supply roughly 533k homes (estimated). It ranks #95 of 401 Indonesia power plants by installed capacity. Commissioned in 2015, it is around 11 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).

In context: how this plant compares
At 426 MW, Celukan Bawang 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.

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 8.2°S — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
This site has effectively no heating season (tropical/equatorial climate), so winter heat loss is not the driver here. The thermal concern shifts to year-round process heat and humidity/heat-driven corrosion of hot equipment.
Climate normals: WorldClim 2.1 (1970–2000 monthly normals, 10 arc-min, CC BY 4.0); zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid). Degree-days & heat-demand index computed by PowerAtlas — a modelled heat-demand proxy, not a measured site figure.
Site climate & environmental severity
This site sits in an extreme marine/tropical environment (estimated ISO 9223 class CX — Extreme), 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.
