EL ARRAYAN — Chile
Wind power plant in Coquimbo, Chile. Approximate location -30.5888, -71.6995.
WindCoquimboChileOnshore
EL ARRAYAN is a 115 MW wind power station in Coquimbo, Chile. It is operated by PARQUE EOLICO EL ARRAYAN SPA. Based on its capacity (estimated), it can supply roughly 98k homes (estimated). It ranks #66 of 336 Chile power plants by installed capacity. Commissioned in 2014, it is around 12 years old — relatively modern. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, wind supplies about 13.1% of Chile's electricity; the national grid averages 289 gCO₂/kWh (66.4% low-carbon) (2025).

In context: how this plant compares
At 115 MW, EL ARRAYAN is well above the median wind plant in Chile (46 MW). Technically it is described as Onshore. Wind turbines convert moving air into electricity; output is variable and site-dependent, and modern turbines deliver some of the lowest-cost new generation on many grids.
Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Local climate & thermal context
This wind plant converts the kinetic energy of wind into electricity through turbine rotors. It sits in a cold semi-arid steppe climate (Köppen BSk) — Southern Hemisphere, latitude 30.6°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 56% 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: 27/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.
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.
