On August 6, 2025, Spain’s Ministry for the Ecological Transition and Demographic Challenge (MITECO) approved €148.5 million in grants for 199 cutting-edge renewable energy installations, all paired with battery storage. According to the ministry, the funded projects will deliver 299.6 MW of mostly photovoltaic generation alongside 351.6 MWh of storage capacity, creating a more stable supply from intermittent solar power. Catalonia leads with 79 approved projects, followed by the Valencian Community (30), Castilla y León (17), and Andalusia (13), signalling broad regional participation in the shift toward renewables with built-in storage. The grants form part of Spain’s RENOINN programme, financed by the EU’s NextGenerationEU Recovery and Resilience Facility, which requires recipients to combine generation with storage for most funding lines. The scale and scope of this commitment mark a strong signal of momentum for Spain’s emerging energy storage sector.
Agrivoltaics with storage—solar arrays integrated into farmland—secured the largest share: €77.1 million for 62 projects, including 19 in the Valencian Community and 13 in Catalonia. These sites will pair crop cultivation with battery-backed solar production, and grantees must report annually for five years on both energy output and agricultural impacts. Floating solar systems, mostly for agricultural irrigation ponds, received €10.1 million for 11 self-consumption plants. Another €23.4 million went to 27 projects integrating renewables into infrastructure such as transport corridors, brownfields, and former industrial sites, adding 45.6 MW and 133.2 MWh of storage. For community energy, €18.2 million was allocated to 67 shared self-consumption projects aimed at 4,000 vulnerable users, combining resilience with potential cost savings.
The Institute for Diversification and Saving of Energy (IDAE) will manage the funding call, oversee technical assessments, and monitor performance over five years. By tying storage to nearly every funded project, MITECO’s strategy moves Spain’s renewable expansion beyond simple generation toward a more flexible, dispatchable model that can deliver power when demand—not daylight—peaks.
