ALTO DE LA SIERRA is a 11.1 MW wind power plant in Aragon, Spain. It is operated by IBERDROLA ENERGIAS RENOVABLES S.A.U.. Based on its capacity (estimated), it can supply roughly 9.4k homes (estimated). It ranks #750 of 899 Spain power plants by installed capacity. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, wind supplies about 20.4% of Spain's electricity; the national grid averages 154 gCO₂/kWh (74.6% low-carbon) (2025).

In context: how this plant compares
At 11.1 MW, ALTO DE LA SIERRA is below the median wind plant in Spain (30 MW). 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 temperate oceanic climate (Köppen Cfb) — Northern Hemisphere, latitude 41.5°N — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
Heating degree-days here run 11% 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: 46/100 — this site sits in the mid 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 moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with humidity / wetness 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.
How it compares & nearby plants
