GABRIEL Y GALAN is a 110 MW hydro power station in Extremadura, Spain. It is operated by IBERDROLA GENERACION S.A.. Based on reported annual generation of 47 GWh, it can supply roughly 13,371 homes. It ranks #105 of 872 Spain power plants by installed capacity. Commissioned in 1982, it is around 44 years old — long-established. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 11.4% of Spain's electricity; the national grid averages 154 gCO₂/kWh (74.6% low-carbon) (2025).

This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a hot-summer Mediterranean climate (Köppen Csa) — Northern Hemisphere, latitude 40.2°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 34% 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: 36/100 — this site sits in the mid 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.

The #34 largest hydro power plant of 124 in Spain by capacity.
Spain has 124 hydro power plants in this dataset, together about 15,659 MW of capacity.
