Data-centre rules
Data centre regulation in Spain
Our tracker lists 7 rules for building and running a data centre in Spain, national and EU, and 3 of them are in force.
Each comes with its status, who it applies to and the next date that matters. When a rule here changes, the change is logged below with its date.

Spain in detail
What the national rules say, with the legal texts.
Spain has a draft Royal Decree, not adopted, on sustainability, resilience and digital sovereignty requirements for data centres. The public hearing ran from 27 August to 10 September 2026. As drafted, it applies to data centres with at least 1 MW of access power that seek grid access and connection permits, including applications already filed but not yet granted. They must reach class A on the EU scale, set for now at a PUE of 1.15 or lower and a WUE of 0.1 or lower. They must also pass one of two renewable tests. In the general case, self-generation or renewable power purchase agreements from recently commissioned plants cover 80% of consumption, and renewable output matches at least 80% of consumption in each hour. Where the national renewable share exceeds 90%, a cap on the hours a site may draw from the grid applies instead. Data centres with 500 kW of IT power or more would also report energy and water data to the ministry each year, for publication. The decree would enter into force 20 days after publication in the Official State Gazette. No approval date is published.
