Spain solar surplus 2026: the Andalusia opportunity

25 March 2026 6 min

12 TWh/year of Andalusian solar are looking for buyers. Why Spain has become the European eldorado of data-center PPAs.

Spain, European solar curtailment champion

With 32 GW of solar installed end of 2025 and a summer peak that exceeds national demand by 15%, Spain is Europe's first victim of solar curtailment.

Why Andalusia?

  • Sunshine: 2,800 h/year vs 1,700 in France
  • Solar LCOE: €28–34/MWh, the lowest in Europe
  • Available land and fast permitting (~14 months)
  • Limited interconnection to France → exports blocked

Current PPA prices

  • 10-year solar PPA: €48–54/MWh fixed
  • 15-year solar PPA: €42–48/MWh fixed
  • 20-year solar PPA: €38–44/MWh fixed

Compare to Spanish average baseload 2025: €78/MWh.
