EXTRESOL-1 is a 150 MW solar power station in Extremadura, Spain. It is operated by EXTRESOL-1 S.L.. Based on its capacity (estimated), it can supply roughly 63,737 homes (estimated). It ranks #97 of 872 Spain power plants by installed capacity. Commissioned in 2009, it is around 17 years old — relatively modern. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, solar supplies about 21.8% of Spain's electricity; the national grid averages 154 gCO₂/kWh (74.6% low-carbon) (2025).

This solar plant converts sunlight directly into electricity with photovoltaic panels. It sits in a hot-summer Mediterranean climate (Köppen Csa) — Northern Hemisphere, latitude 38.6°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 44% 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: 32/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.
In colder climates, uninsulated hot equipment (boilers, turbines, valves, steam lines) loses proportionally more heat to ambient air — exactly the loss Inzonex modular insulation is designed to cut.
Solar PV loses ~0.35%/°C above 25°C cell temperature — roughly 0.2% at warm-season highs here (estimate).

The #4 largest solar power plant of 243 in Spain by capacity.
Spain has 243 solar power plants in this dataset, together about 4,901 MW of capacity.
