Overview
What it means
Data centres with installed IT power demand of at least 500 kW must report indicators including energy consumption, PUE, WUE, waste-heat reuse and renewable-energy share. Operators submit facility-level information to the European database, while the regulation generally provides for public dissemination through aggregated national and EU statistics rather than a complete public record for every individual facility.
How it is used
Operators compile and submit the required KPI set annually. The Commission and national authorities use the information for sector comparison, planning and policy development; public users should not assume that every facility-level submission is openly identifiable.
Why it matters
The scheme turns a rapidly growing infrastructure footprint into a consistent regulatory evidence base. It improves scrutiny of the sector while retaining important limits on what facility-level information is publicly disclosed.
Current status
First reporting round 2024; common rating scheme in development (draft delegated act, 2026).
