ABONO 2 is a 877.7 MW coal power station in Asturias, Spain. It is operated by HIDROELECTRICA DEL CANTABRICO S.A.. Based on reported annual generation of 6,000 GWh, it can supply roughly 1.7 million homes. It ranks #25 of 899 Spain power plants by installed capacity. Commissioned in 1985, it is around 41 years old — long-established. Its modelled annual emissions are 806,160 t CO₂/yr (Climate TRACE), equivalent to about 188k cars driven for a year. In context, coal supplies about 0.3% of Spain's electricity; the national grid averages 154 gCO₂/kWh (74.6% low-carbon) (2025).

In context: how this plant compares
At 877.7 MW, ABONO 2 is well above the median coal plant in Spain (515.6 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.

Local climate & thermal context
This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a temperate oceanic climate (Köppen Cfb) — Northern Hemisphere, latitude 43.6°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 18% 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: 43/100 — 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 corrosive environment (estimated ISO 9223 class C4 — High), 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.
