TALTAL — Chile
Gas power plant in Antofagasta, Chile. Approximate location -24.9888, -70.466.
GasAntofagastaChile
TALTAL is a 240 MW gas power station in Antofagasta, Chile. It is operated by ENDESA. Based on its capacity (estimated), it can supply roughly 270k homes (estimated). It ranks #42 of 336 Chile power plants by installed capacity. In context, gas supplies about 15.3% of Chile's electricity; the national grid averages 289 gCO₂/kWh (66.4% low-carbon) (2025).

In context: how this plant compares
At 240 MW, TALTAL is below the median gas plant in Chile (379 MW). Gas plants burn natural gas either in open-cycle turbines for fast peaking, or in combined-cycle units that recover exhaust heat in an HRSG to reach roughly 55–62% efficiency — the cleanest-burning fossil option.
Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Local climate & thermal context
This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a cold desert climate (Köppen BWk) — Southern Hemisphere, latitude 25.0°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 70% 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: 24/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.
A gas turbine here also runs ~1% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).
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 a corrosive environment (estimated ISO 9223 class C4 — High), with dust abrasion 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.
