Accelerating Energy Storage in Spain: Regulatory Urgency and Technological Strategies for a Sustainable Future
The energy storage sector in Spain is at a pivotal point with increasing investment interest technological progress and supportive European regulations driving growth.
Despite these positive signals administrative delays and a lack of clear regulatory frameworks continue to hinder project development and deployment.
During the third edition of the Storage Forum organised by El Periodico de la Energia leaders from major energy firms called for swifter regulatory processes stable legal environments and economic mechanisms to accelerate battery adoption.
Daniel Fernandez Alonso from Engie emphasised the favourable outlook following the approval of Royal Decree-Law 7 2025 highlighting demand access connection improvements and capacity mechanisms as vital for project stability.
He also indicated that signals from Brussels are promising with potential capacity auctions expected before year end underlining the importance of a consistent regulatory approach.
However Engie warned that many of these measures remain yet to be practically implemented. They stressed that faster administrative procedures and faster regulation are crucial to prevent project delays.
Representing developers Lourdes Llana from RIC Energy acknowledged regulatory progress but pointed out ongoing issues with administrative clarity and social opposition. She noted that misconceptions about storage technologies often lead to rejection and cost impositions.
Technical and regulatory hurdles still challenge developers especially for hybrid projects due to incomplete regulations governing auxiliary services and connection procedures.
MarIa Perez of Naturgy emphasised that energy storage models must evolve as integral tools for managing risks and stabilising the grid rather than solely as financial products.
She highlighted that falling costs and built-in renewable infrastructure have improved profitability prospects but warned about operational complexities in the market.
Similarly Marta Fernandez of Acciona Energy advocated for leveraging existing renewable infrastructure to maximise grid utilisation and reduce investment costs. She also stressed the strategic importance of long-duration hydraulic pumping for system stability and called for enhanced inter-agency coordination.
Venancio Javier Rodriguez from Endesa underscored the necessity of deploying storage where it offers genuine value rather than based solely on connection capacity. He criticised the current approach of developing projects without clear planning which risks future technical and economic issues.
He called for more rational planning driven by territorial and demand analysis along with capacity release mechanisms to unblock current network constraints.
Despite differing perspectives all participating firms agreed that Spain possesses the technology capital and corporate interest to lead in energy storage within Europe. Nonetheless faster regulation and reduced administrative uncertainty are crucial to avoid further delays and unlock the full potential of batteries for the future electrical system.
