Spain mandates data centres run mostly on renewables

Spain has introduced a requirement that data centres source the majority of their electricity from renewables, according to Recharge News. The rule directly targets one of the fastest-growing load categories in the Iberian zone.

The policy raises the compliance bar for operators already competing for renewable capacity in a zone where solar curtailment and grid congestion are live constraints. Data centre developers with signed or pending connection agreements in Spain will need to demonstrate renewable sourcing at the majority level, which typically flows through PPAs, on-site generation, or guarantees of origin matched to consumption.

No specific percentage threshold or phase-in timeline was published in available reporting. Operators active in the Spanish zone should monitor the official gazette for the full regulatory text. The rule adds Spain to a short list of European jurisdictions imposing supply-mix conditions on data centre load, ahead of any harmonised EU-level standard.
