EU data-centre energy reporting is in force; a rating scheme is still being built

The European Commission’s energy-performance page for data centres records a reporting obligation under the Energy Efficiency Directive, a delegated regulation (EU/2024/1364), a July 2025 assessment of the 2024 reporting period, and a 26 March–23 April 2026 call for feedback on a draft EU-wide rating scheme. Those are transparency and policy steps. They do not publish a Swedish hall PUE in this register and they do not allocate megawatts.

The Commission page used here explains why the file exists. Data centres are described as growing infrastructure whose energy demand is a challenge. The page cites the IEA for a global electricity-consumption figure of about 1.5 percent, or 415 TWh, with a projection toward 945 TWh by 2030, driven mainly by accelerated computing for AI. Those are global context sentences. They are not a Swedish consumption census and not a site connection offer.

The legal instrument in force is reporting. The Energy Efficiency Directive introduced an obligation to monitor and report the energy performance of data centres. Delegated Regulation (EU) 2024/1364 sets out the information and key performance indicators. A European database collects and publishes data relevant to energy performance and water footprint for data centres with significant energy consumption. Reporting is not a permit, and a database row is not a Swedish commissioning certificate.

Assessment has started. In July 2025 the Commission published a report analysing data submitted in the 2024 reporting period. It also provides an aggregated online dashboard. Those products describe what operators reported under the scheme. They do not, in the pages used here, attach a PUE or water figure to Horndal, Falun, Kista or Luleå. If a later public extract names a Swedish facility, that extract can open a new row.

The next policy step is still incomplete. The Commission says it is preparing a Data Centre Energy Efficiency Package that will assess reported data, introduce a rating scheme and launch work on minimum performance standards. A call for feedback on a draft regulation for a common EU-wide rating scheme ran from 26 March to 23 April 2026. A draft and a consultation are not an adopted rating on a named Swedish hall.

Practical support pages are dated. The Commission lists a user manual and reporter guide of 3 September 2025, an FAQ of 28 July 2026, and a list of national contact points dated 11 March 2026. Those dates help a compliance file. They do not tell a land buyer whether a Swedish plot has spare power.

For a Swedish operator or investor the useful questions are institutional. Does the facility meet the reporting threshold? Which national contact point applies? Which reporting year is closed? Has any published dashboard figure been correctly scoped to the legal entity and the hall? Separately, what do the municipal, environmental and network files say? Those questions do not collapse into one PUE headline.

DataCenterSweden records the Commission page as a live EU policy source. It does not invent a Swedish performance score, does not convert the IEA projection into a Nordic megawatt need, and does not treat the unfinished rating scheme as a site decision. The next update would be a later adopted act or a public extract that actually names a Swedish facility.

Why it matters

EU reporting will show up in Swedish data rooms. It is useful as a compliance and transparency check, not as a spare-power map or a ready-made PUE league table.

What remains unknown

This register does not contain a published EED extract that names a Swedish hall’s PUE, water use or IT load, and the EU-wide rating scheme is not yet an adopted site score.
