Wedoany.com Report-Dec.2, Spain's Institute for the Diversification and Saving of Energy (IDAE) has published the Final Proposed Resolution for the first call of its innovative energy storage support programme, originally launched in May 2025 and co-financed by European Regional Development Fund (ERDF) resources for the 2021–2027 period.

Following provisional results announced in late October, the final decision approves funding for 133 projects with a combined power capacity of nearly 2,400 MW and total energy storage capacity of approximately 10,000 MWh.

The selected initiatives cover a range of advanced storage technologies designed to enhance grid flexibility and support greater integration of renewable generation across Spain. The aid package forms part of broader national efforts to strengthen energy system resilience and accelerate the transition toward higher shares of renewable electricity.

Awarded projects will now proceed to the formal grant acceptance phase, enabling implementation to begin once administrative requirements are completed. The substantial capacity approved in this initial call demonstrates strong industry response and underlines the growing role of energy storage in Spain's evolving electricity infrastructure.
