"Resilience" is in the title of Spain's data centre decree. It is not in the articles

The consultation window closed today at 17:00. The draft is called "energy and environmental sustainability, resilience and digital sovereignty requirements applicable to data centres", and its article 5 carries "resilience" in the heading. Read in full, it creates not a single resilience requirement: it defers them to whatever regulation already applies to you. We think that is sound legislative technique and bad news for anyone hoping somebody would hand them availability. It does not bind you — the threshold is 1 MW of grid access capacity — but it will reach you anyway, through the contract of whoever hosts you.

Spain's data centre decree is not decided by the 80% renewables rule: it is decided by a PUE of 1.15

On 27 August Spain opened public consultation on the draft royal decree regulating data centres. Coverage stopped at the 80% hourly renewables rule. We read all 32 pages and there are three things inside that almost nobody has reported: the surcharge scale in article 10, reaching 500% on network tolls and charges; a sentence in article 5.2(b) that leaves the customer's data outside the sovereignty the operator declares; and, in our judgement, the number that really filters projects, a PUE of 1.15 in the fourth transitional provision (with a WUE of 0.1 L/kWh), which the preamble itself acknowledges are the class "A" values proposed by the European Commission. Amazon reported a global PUE of 1.14 in 2025 and 1.15 in 2024.
