Coal power plant in Atacama, Chile. Approximate location -28.4673, -71.2573.
CoalAtacamaChile
GUACOLDA is a 760 MW coal power station in Atacama, Chile. It is operated by AES GENER S.A.. Based on its capacity (estimated), it can supply roughly 951,085 homes (estimated). It ranks #4 of 315 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).

This facility's annual emissions are roughly equivalent to:
Estimated, not measured: from installed capacity at a typical 50% load factor × a typical coal emission factor (~1000 g CO₂/kWh, IPCC AR5 / US EIA). Actual emissions depend on plant efficiency and running hours.Equivalencies via US EPA Greenhouse Gas Equivalencies.

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 28.5°S — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
Heating degree-days here run 50% below the median power plant in this dataset — a proxy for how much extra energy heated equipment must replace through its surfaces in winter.
Climate heat-demand index: 29/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.
In colder climates, uninsulated hot equipment (boilers, turbines, valves, steam lines) loses proportionally more heat to ambient air — exactly the loss Inzonex modular insulation is designed to cut.

The #2 largest coal power plant of 14 in Chile by capacity.
Chile has 14 coal power plants in this dataset, together about 4,839 MW of capacity.
