The 50 Largest Solar Plants in Spain: Updated 2026 Ranking
Spain is home to some of the largest photovoltaic installations on earth. With over 6,000 utility-scale solar plants connected to the national grid and cumulative installed capacity exceeding 30 GW, the country has transformed itself in a decade from a solar also-ran into the undisputed leader of European solar power.
This article presents the updated 2026 ranking of the 50 largest solar plants in Spain by installed capacity (MWp). Each entry includes location, owner, capacity and commissioning date. For the full interactive database — filterable by province, owner and power range — visit the PV Maps plant inventory.
Why This Ranking Matters
Knowing which plants are the largest is not just trivia. For professionals in the sector, this data serves concrete commercial purposes:
- O&M companies can identify which large assets are coming up on their 5-year O&M contract review cycle and target prospecting accordingly.
- Market representation firms can analyse how the biggest operators are performing in the energy market and build competitive intelligence for their pitches.
- Investors can use the commissioning date and owner data to identify assets that may be in acquisition review or portfolio restructuring.
- Developers can benchmark their own projects against operational peers.

Key Patterns in Spain’s Largest Solar Plants
Extremadura Dominates
Of the top 10 plants, 7 are located in Extremadura (Cáceres or Badajoz provinces). The combination of Spain’s highest irradiance levels, abundant flat land with low agricultural value, and robust grid infrastructure makes Extremadura the natural home of utility-scale solar.
Concentration Among Major Owners
Spain’s largest energy utilities collectively own roughly 40% of the top 50 plants by capacity. The remaining 60% is split among independent power producers, infrastructure funds and international energy companies. Want to know exactly who owns each plant? Contact us for full ownership data.
The 2021-2023 Build Wave
The vast majority of plants in the top 50 were commissioned between 2021 and 2023, reflecting the development pipeline that was assembled in 2017-2019 and delayed by permitting bottlenecks and COVID-19 supply chain disruptions. A new build wave is now underway for 2024-2026.
