Spain high-voltage grid and renewable energy map
Recommended BESS sitesPreview Estimated score and suggested size per 110 kV+ substation. Tap to zoom in.
How is this calculated? Score: voltage level 35%, nearby solar + wind (30 km) 35%, number of connected lines 20%, little nearby hydro 10%. Size: 10–50 MW at 110 kV, 40–150 MW at 220 kV, 100–300 MW at 400 kV, scaled up by nearby solar/wind and line count. 2-hour duration. Real free grid capacity is not public, so this is an estimate.
