New developments in processing renewable projects, storage, repowering and grid access
On 6 November 2025, Royal Decree 997/2025 approving urgent measures to strengthen the electricity system was published in the Official State Gazette (BOE). The regulation introduces new developments in the processing of renewable projects, storage, repowering, and grid access for demand-side installations, among which the following stand out:
- It strengthens (i) supervision and verification of compliance with obligations by all agents in the electricity sector, and (ii) data transparency.
- It reformulates the definition of installed capacity for the purposes of obtaining administrative authorizations for both storage and generation facilities.
- It includes specific measures to boost hybrid storage in renewable projects, orienting storage facilities toward spaces already occupied by infrastructure.
- It establishes the Spanish government’s commitment to developing a national roadmap to promote repowering.
- It regulates the phases of operating authorizations—provisional and final—enabling partial authorizations to be granted for projects that share common infrastructure.
- It concludes the regulation of the access conditions for demand facilities.
- It temporarily relaxes the requirements for obtaining the administrative operating authorization (“AAE”).
