西班牙储能政策重大突破：储能明确列为“公共用途”

Core Viewpoint - The Spanish government approved Royal Decree 7/2025 on June 24, addressing key issues hindering the safe and legal deployment of energy storage projects, marking a significant breakthrough for energy storage development in Spain [1][2]. Group 1: Regulatory Changes - The new regulation exempts energy storage facilities from environmental assessment procedures if located within the boundaries of renewable energy plants that have passed environmental evaluations, significantly shortening project approval timelines [1][2]. - Energy storage facilities and their related power connection infrastructure are now explicitly classified as "public utility," granting them the same legal support as generation facilities in terms of land acquisition and approval processes [2]. - The definition of "installed capacity" has been clarified to refer to the maximum output power of inverters, altering the approval authority for mixed projects based on capacity thresholds [2]. Group 2: Project Approval and Prioritization - The new rules eliminate discriminatory treatment of mixed generation projects in technical limit directives, ensuring all renewable energy plants receive priority during grid congestion, thus becoming the last to be curtailed [2]. - Energy storage facilities will now have flexible access permissions on the demand side, distinguishing their identity from that of electricity consumers [3]. Group 3: Implementation and Future Considerations - The Royal Decree has a 30-day temporary effectiveness period, requiring approval from the Congress to be permanently integrated into the legal framework; failure to pass will result in the automatic expiration of all provisions [3]. - The regulation also outlines the roles of independent aggregators in the behind-the-meter (BTM) storage sector, indicating a need for further discussions and refinements [3]. Group 4: Context of Regulatory Changes - The regulatory changes were prompted by a significant power outage on April 28, where the grid supply dropped by approximately 60% within five seconds, affecting both Spain and Portugal [5][6]. - The outage was attributed to a sudden voltage surge and inadequate voltage control capabilities within the Spanish electricity system, highlighting the need for improved regulatory oversight and grid construction [6].
