# EU EED Article 12 data centre reporting and performance

Article 12 of the EU Energy Efficiency Directive requires qualifying data centre owners and operators to publish annual energy performance information and feed the European database.

*EED Article 12* *Data centres* *EU*

## EU Energy Efficiency Directive Data centre reporting and performance

Article 12 focuses on owners and operators of EU data centres whose installed IT power demand reaches the reporting threshold.

Use this page to check the trigger, reporting cadence, Annex VII data categories, European database publication, and evidence that should support a defensible submission.

Article 12 of Directive (EU) 2023/1791 creates a transparency regime for data centres. It is not a general corporate energy-audit page: the relevant question is whether a data centre in an EU Member State reaches the installed IT power-demand threshold and must make Annex VII energy-performance information publicly available each year.

## When Article 12 data centre reporting is triggered

Member States must require owners and operators of data centres in their territory to publish Annex VII information where the data centre has installed information technology power demand of at least 500 kW. The reporting trigger is tied to the data centre and its installed IT power demand, not to enterprise size, corporate revenue, or a generic sustainability-reporting category.

The Directive excludes data centres used for, or providing services exclusively with the final aim of, defence and civil protection. A separate Article 12 provision says Member States should encourage data centres with installed IT power demand equal to or greater than 1 MW to take account of the European Code of Conduct on Data Centre Energy Efficiency.

- Start with an inventory of EU data centres, owners, operators, municipality, operating start date, and installed IT power demand.
- Classify whether each site is at least 500 kW installed IT power demand for Article 12 publication.
- Record any defence or civil-protection-only exclusion before removing a site from the reporting population.
- Flag sites at or above 1 MW installed IT power demand for European Code of Conduct best-practice review.
- Keep the calculation basis for installed IT power demand with the reporting file, because the threshold drives the obligation.

*Placement: after evidence section*

## Prepare an Article 12 data-centre reporting file

Turn the EED Article 12 threshold, Annex VII fields, and European database workflow into a recurring evidence pack for each qualifying EU data centre.

## Annual reporting cadence and European database

The Directive states that the Article 12 publication obligation applies by 15 May 2024 and every year thereafter. The Commission news release on Delegated Regulation (EU) 2024/1364 describes the first reporting date for operators as 15 September 2024, followed by 15 May in 2025 and subsequent years.

The Commission has prepared a European database for the energy performance and water footprint of data centres. Article 12 says the database includes information communicated by obligated data centres and is publicly available at aggregated level, so internal evidence should separate site-level submission data from what appears in public aggregated outputs.

- Set the annual reporting calendar around the 15 May recurring date after the first 2024 reporting period.
- For historical 2024 work, distinguish the Commission's 15 September 2024 delegated-regulation reporting date from the recurring 15 May cycle.
- Keep proof of database registration, reporter role assignment, submitted values, validation checks, and any corrections.
- Retain the public-publication decision for information withheld under trade-secret, business-secret, or confidentiality law.
- Reconcile submitted values to internal metering, operations, facilities, water, renewable-energy, and heat-reuse records before filing.

## What Annex VII data must be prepared

Annex VII groups the required information into site identity, capacity and activity data, and performance indicators for the last full calendar year. A useful reporting pack should therefore combine legal-entity ownership data with technical facility data and measured annual performance values.

The Directive names performance topics rather than a single metric: energy consumption, power utilisation, temperature set points, waste heat utilisation, water usage, and use of renewable energy. Until the delegated act under Article 33(3) applies, Annex VII points to the CEN/CENELEC EN 50600-4 data-centre facilities and infrastructure series where applicable.

- Identity fields: data-centre name, owner, operator, operating start date, and municipality.
- Scale and activity fields: floor area, installed power, annual incoming and outgoing data traffic, and amount of data stored and processed.
- Performance fields: last full calendar-year energy consumption, power utilisation, temperature set points, waste heat utilisation, water usage, and renewable-energy use.
- Methodology fields: data source, meter or system of record, reporting boundary, aggregation method, reviewer, and version date for each reported value.
- Confidentiality fields: which Annex VII items are published, withheld, or aggregated, and the legal basis for any withheld trade-secret or confidential information.

## How the performance scheme and next steps affect planning

Delegated Regulation (EU) 2024/1364 is the first phase of an EU-wide scheme to rate data-centre sustainability. The Commission states that the delegated act sets out the information and key performance indicators to be reported and defines the first sustainability indicators for rating data centres.

Article 12 also required the Commission to assess available submitted data by 15 May 2025 and report to the European Parliament and Council, including possible further measures such as minimum performance standards and a net-zero data-centre-sector feasibility assessment. Teams should avoid assuming a final minimum-performance standard unless they can point to a later binding measure.

- Treat current Article 12 work as monitoring, reporting, publication, and evidence preparation, not as proof that a site has met a future performance standard.
- Track Delegated Regulation (EU) 2024/1364 outputs separately from the Directive text so KPI definitions and methodology changes are not mixed with the Article 12 threshold.
- Prepare trend views for energy use, water use, renewable-energy use, cooling settings, and waste-heat utilisation because the Commission uses submitted data to assess efficiency.
- Do not publish claims such as 'EED-compliant data centre' unless the claim states exactly which Article 12 reporting step or database submission was completed.
- Keep a watch item for any later EU minimum performance standards, but do not invent dates, penalties, or pass/fail labels before they are grounded in a binding source.

## Evidence file for an Article 12 data centre report

A defensible evidence file should let a reviewer trace each public or database-reported value back to the site boundary, meter or operational system, calculation method, and approval owner. The highest-risk gaps are usually threshold calculations, unreviewed confidentiality exclusions, and performance numbers copied from dashboards without a stable reporting boundary.

Because Article 12 data can feed public transparency, aggregated database outputs, Commission assessment, and the rating scheme, the evidence pack should be maintained as a recurring annual reporting file rather than a one-off compliance memo.

- Scope record: EU site list, owner/operator mapping, municipality, operating start date, installed IT power-demand calculation, and any exclusion rationale.
- Data workbook: Annex VII field list, data source, reporting boundary, calculation method, last full calendar-year values, reviewer, and approval status.
- Confidentiality log: Annex VII items withheld or aggregated, legal rationale, approving owner, and publication wording.
- Submission record: platform registration, reporting account, submitted values, timestamps, validation messages, correction history, and exported receipt where available.
- Performance trend pack: annual energy, power-utilisation, temperature, waste-heat, water, and renewable-energy values with notes on material methodology changes.
