Royal Decree-Law 7/2026 on Sustainability Requirements for Datacenters in Spain
Driven by the demand for artificial intelligence and cloud computing, permit applications for new data centers in Spain have surged beyond official forecasts.
While the Artificial Intelligence Strategy 2024 targeted 2.5 GW of computing power by 2030 (requiring roughly 3.5 to 4 GW of electricity capacity), granted network connection permits have already surpassed 12 GW.
In response, the Spanish government enacted Royal Decree-Law 7/2026 and introduced its implementing Royal Decree framework. The aim is to shift to sustainable datacenter deployment that protects the national grid, ensures renewable energy investment, and advances European digital sovereignty.
New Regulatory Framework
To prevent speculative projects from monopolizing scarce electricity transport capacity and water resources, the regulation introduces new operational conditions for data center operators seeking access power of 1 MW or more.
Transparency and reporting rules start at 500 kW IT power to align with EU Directive 2023/1791. Facilities must meet Class "A" ratings on the European performance scale once official EU labeling takes effect in August 2027.
In the interim, new data centers must deliver strict performance metrics:
Power Usage Effectiveness (PUE): Maximum 1.15
Water Usage Effectiveness (WUE): Maximum 0.1
Mandatory Renewable Thresholds
Data centers must ensure that at least 80% of their electricity usage is matched with new renewable generation on an hour-by-hour basis via self-consumption or forward Power Purchase Agreements (PPAs) with assets commissioned no more than 18 months prior.
If the national grid’s overall renewable integration exceeds 90%, access permits can be granted without proving prior additionality, though consumption hours remain capped relative to real-time green energy availability.
Non-compliance risks losing network access and connection permits entirely (caducidad automática), alongside capacity reservation charges and regulatory surcharges
To strengthen resilience, the framework mandates that operators of large facilities be legally established within the EU. Furthermore, operational data, metadata, and system logs handled by these datacenters must remain within EU jurisdiction to maintain grid rights.
What This Means for DataCenter Developers
For infrastructure developers, technology vendors, and power providers, Spain’s regulatory framework confirms that building data center infrastructure in Europe will increasingly require pairing new computing capacity directly with clean power generation and battery storage solutions.
Grid allocation and sustainability requirements ensure quality prevails over quantity in new connections, aligning digital expansion with the social, energy, and environmental priorities of Spain.
