Coal power plant in Atacama, Chile. Approximate location -27.366667, -70.333333.
CoalAtacamaChile
Castilla power station is a 2,100 MW coal power station in Atacama, Chile. It is operated by Eneva SA [100%]. Based on its capacity (estimated), it can supply roughly 2.6 million homes (estimated). It ranks #1 of 336 Chile power plants by installed capacity. In context, coal supplies about 17.8% of Chile's electricity; the national grid averages 289 gCO₂/kWh (66.4% low-carbon) (2025).

At 2,100 MW, Castilla power station is well above the median coal plant in Chile (478 MW). 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 cold desert climate (Köppen BWk) — Southern Hemisphere, latitude 27.4°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).
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 dust abrasion 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 #1 largest coal power plant of 22 in Chile by capacity.
Chile has 22 coal power plants in this dataset, together about 12,437 MW of capacity.
