EED data-centre reporting, explained for operators

Who must report

Any data centre in the EU with an installed IT power demand of at least 500 kW reports annually, regardless of type: enterprise, colocation, or co-hosting. Member states may widen the scope but cannot narrow it. Germany reports at 300 kW of net connected power and France pulls the threshold down to 100 kW, so a facility that is out of scope EU-wide can still be in scope nationally.

The first cycle (calendar year 2023 data) closed in September 2024, and the 15 May 2026 deadline for CY2025 has passed. The cycle that matters now covers calendar year 2026, due 15 May 2027. The first-year grace provisions that let operators omit hard-to-measure datapoints no longer apply.

What gets reported

Delegated Regulation (EU) 2024/1364 defines the content everywhere in the EU: facility identification and redundancy levels (Annex I), and 24 key performance indicators (Annex II) spanning energy, water, waste heat, renewables, ICT capacity, and data traffic. From those, the reporting platform computes four sustainability indicators: PUE, WUE, ERF, and REF.

The inputs are less exotic than the acronyms suggest: twelve months of electricity and water bills, meter or BMS readings where they exist, and a small set of declared facts about the facility. The hard part is provenance. Every figure must stay traceable to the document it came from, because measured and estimated values are not interchangeable once caps and verification enter the picture.

The colocation wrinkle

Colocation operators must report ICT capacity and data traffic for equipment they do not own. The regulation allows extrapolation covering at least 90 percent of new-equipment IT power and asks operators to state the share of computer-room floor area their figures cover. In practice this means colocation operators need a data relationship with their tenants that most contracts never anticipated.

Confidential filings, public aggregates

Your facility-level submission is confidential by regulation: the Commission and member states must treat it as commercially sensitive, and the EU database publishes only aggregated statistics. There is no public register of individual filings. That is precisely why buyer-facing, named comparisons live outside the filing system, and why operators who can show verified numbers stand out.

How NRGKit files it

We compute the 24 datapoints from your bills and exports with deterministic, auditable code, flag what is missing with a gap report, and produce the filing pack against the current template version for your register. Every figure carries its lineage. You review and sign before anything is submitted: you remain the filer of record, and no filing leaves draft status without a human signature.

Founding Filing Partners get the whole 2027 filing season done with them for £1,950 for the year, including the capacity headroom readout computed from the same bills.
