European Energy MarketsBackground
The Energy Efficiency Directive (EU) 2023/1791 sets binding energy-efficiency targets for the European Union and places obligations on each member state. Its duties need national law to take effect, so its reach depends on how each capital transposes it.
One of those duties covers computing infrastructure. Article 12 requires data centres of 500 kW and above to report their energy and water performance. Spain's draft data-centre decree, whose consultation closed on 10 September 2026 with an 80% hourly-matched renewables test, would serve as the Spanish route for that reporting.
The text itself changed on 5 August 2026 without any national act. Article 93 of the recast gas directive, Directive (EU) 2024/1788, applied from that date by force of its Article 96. It deleted Articles 17 and 19 of the Energy Efficiency Directive and replaced part of its Article 39.
