Spain solar surplus 2026: the Andalusia opportunity
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.
Data centers moving in
- AWS Aragón: 2.5 GW planned by 2030
- Microsoft Madrid: 1 GW phase 1
- Meta Talavera: 600 MW
- Equinix Barcelona: 400 MW extension
The Voltarione effect
We list 47 Andalusian solar parks (50–250 MW each) currently in partial surplus. Quote request from the Spain page in 60 seconds.

How much electricity does an AI data center really consume? A 2026 European benchmark (MW, €/MWh, PPA)
A frontier AI training cluster now draws 100–300 MW continuously, inference already accounts for 80–90% of AI compute, and the all-in energy cost of a 100 MW campus ranges from €38–55M/year in the Nordics to €118–149M/year in Dublin. A data-heavy 2026 European benchmark.

How European AI data centers can secure low-carbon power in weeks, not years, by combining renewable surplus, hourly matching and producer mapping. Structured for search engines, AI assistants and energy buyers.
Electricity surplus for data centers in Europe: the market about to redefine digital energy access
100 TWh today, 236 TWh by 2035: why European renewable surplus is the natural answer to data center energy hunger, and how Voltarione connects the two directly.
