Zabalgarbi power station is a 96 MW waste power plant in Basque Country, Spain. It is operated by Zabalgarbi Ltd. Based on its capacity (estimated), it can supply roughly 132k homes (estimated). It ranks #137 of 899 Spain power plants by installed capacity. Its modelled annual emissions are 26,927 t CO₂/yr (Climate TRACE), equivalent to about 6.3k cars driven for a year. In context, the national grid averages 154 gCO₂/kWh (74.6% low-carbon) (2025).

Known, modelled and calculated values are kept separate. Missing fields are shown as unavailable.
The capacity and fuel fields on this page are source-record values from the upstream open dataset. They are useful for identification and ranking, but they have not been upgraded to a 2026 registry/GEM-location verified value.

At 96 MW, Zabalgarbi power station is well above the median waste plant in Spain (16 MW). Waste-to-energy plants burn municipal solid waste to generate electricity and heat, cutting landfill volume while recovering energy from residual waste.

This waste plant recovers energy by combusting municipal or industrial waste. It sits in a temperate oceanic climate (Köppen Cfb) — Northern Hemisphere, latitude 43.3°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 30% 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: 38/100 — 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.
For a plant’s outdoor hardware — heat-recovery steam generators (HRSG), expansion joints, valves, flanges and their insulation — the local climate sets how fast unprotected steel and coatings degrade. This site sits in a corrosive environment (estimated ISO 9223 class C4 — High), with humidity / wetness the leading environmental stress.
Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.
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.
The #1 largest waste power plant of 18 in Spain by capacity.
Spain has 18 waste power plants in this dataset, together about 628 MW of capacity.
