Sogama power station — Spain

Sogama power station is a 71.7 MW waste power plant in Galicia, Spain. It is operated by Sociedade Galega do Medio Ambiente SA. Based on its capacity (estimated), it can supply roughly 99k homes (estimated). It ranks #172 of 899 Spain power plants by installed capacity. Its modelled annual emissions are 20,993 t CO₂/yr (Climate TRACE), equivalent to about 4.9k cars driven for a year. In context, the national grid averages 154 gCO₂/kWh (74.6% low-carbon) (2025).

Data provenance

Capacity and fuel are the upstream open-dataset record, not yet matched to a 2026 registry or GEM entry.

capacity: Climate TRACE; fuel: facility name / public source type explicitly indicates waste-to-energy or municipal waste facility

In context: how this plant compares

At 71.7 MW, Sogama power station is well above the median waste plant in Spain (16.4 MW). Waste-to-energy plants burn municipal solid waste to generate electricity and heat, cutting landfill volume while recovering energy from residual waste.

Local climate & thermal context

This waste plant recovers energy by combusting municipal or industrial waste. It sits in a warm-summer Mediterranean climate (Köppen Csb) — Northern Hemisphere, latitude 43.2°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 an aggressive, high-corrosion environment (estimated ISO 9223 class C5 — Very high), with marine salt corrosion 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.
