The register.
Regulation in this market moves faster than marketing copy does, and a good deal of what circulates as fact is a summary of a summary. So every regulatory statement on this site is an entry here, with its source and the date we read it, and the build fails if a page cites something that is not in the register.
The open items at the bottom are open. They are questions where the position genuinely moved recently, or where the answer is consequential enough that we would rather show the working than assert a number.
Article 12 of the Energy Efficiency Directive (EU) 2023/1791 places an annual reporting obligation on data centres with an installed IT power demand of at least 500 kW. Enterprise, colocation and co-hosting facilities are all in scope.
Member States transposing Article 12 may lower the 500 kW threshold but may not raise it. The scope is therefore wider in some Member States than the Directive's floor.
Directly relevant to siting: a facility below 500 kW at Union level may still be in scope nationally.
Commission Delegated Regulation (EU) 2024/1364 sets the first phase of a common Union rating scheme for data centres and specifies 24 reportable data points across energy, sustainability indicators, ICT capacity and data traffic.
The first reporting period was due by 15 September 2024 covering calendar year 2023. Subsequent reports are due annually by 15 May.
The reported sustainability indicators are Power Usage Effectiveness (PUE), Water Usage Effectiveness (WUE), Energy Reuse Factor (ERF) and Renewable Energy Factor (REF).
The Union-wide data centre rating scheme foreseen by the Energy Efficiency Directive is not yet in force. No facility may be described as holding an EU rating.
Register only until the scheme is adopted. Machine Core Systems claims no rating.
Germany's Energieeffizienzgesetz requires data centres commencing operation from 1 July 2026 to achieve a PUE of 1.2 or lower. A draft amendment published in 2026 would raise that figure to 1.3.
Both figures must be shown together. Citing 1.2 alone misstates the current position; citing 1.3 alone states a draft as law.
Under the draft amendment, facilities operating before 1 July 2026 would meet an annual-average PUE of 1.6 from 1 July 2027 and 1.4 from 1 July 2030, relaxed from the current 1.5 and 1.3.
Facilities coming online from July 2026 must reach an Energy Reuse Factor of 10 percent, rising to 15 percent in 2027 and 20 percent in 2028.
The Netherlands limits hyperscale data centres to 10 hectares and caps their grid connections at 70 MW, admitting new hyperscale development only in Eemshaven, the Schiphol region, and Hollands Kroon.
Introduced under the Rutte IV cabinet in 2022. It is a siting and connection cap, not a prohibition — do not describe it as a ban.
Amsterdam and Haarlemmermeer imposed a further round of municipal restrictions in December 2023, on top of the national hyperscale limits, driven by a shortage of grid capacity.
The ISO/IEC 30134 series defines the data centre key performance indicators: 30134-2 Power Usage Effectiveness, 30134-3 Renewable Energy Factor, 30134-6 Energy Reuse Factor, 30134-9 Water Usage Effectiveness.
The EN 50600 series is the European standard for data centre facilities and infrastructures, covering power distribution, environmental control, physical security, management and operational information, and energy efficiency.
A PUE figure is not comparable unless its measurement category is declared. The categories differ in where and how often energy is measured, and a facility can report materially different PUE values under each.
This is the whole argument of the measurement page. A bare PUE number is a marketing artefact, not an engineering one.
DMTF Redfish (DSP0266) defines a standard HTTPS and JSON interface for platform telemetry, including power and thermal metrics, and is the vendor-neutral basis for automated energy measurement.
EN/IEC/UL 62368-1 is the unified safety standard for information technology and audio-video equipment, replacing IEC 60950-1 and IEC 60065.
ASHRAE Technical Committee 9.9 publishes the thermal guidelines that define the environmental classes data centre equipment is specified against.
The Cyber Resilience Act (EU) 2024/2847 imposes cybersecurity obligations on products with digital elements, including vulnerability handling, a software bill of materials, and support across the expected product lifetime.
The Data Act (EU) 2023/2854 places design obligations on connected products and switching obligations on data processing services, including the withdrawal of switching charges.
The Radio Equipment Directive delegated regulation (EU) 2022/30 applies cybersecurity requirements to internet-connected radio equipment, with EN 18031 as the harmonised standard family.
Directive (EU) 2024/825 on empowering consumers for the green transition restricts generic environmental claims that cannot be substantiated. An efficiency claim without a stated workload, standard, measurement point and date is not substantiated.
This is why no comparative efficiency percentage appears anywhere on this site.
The AI Act (EU) 2024/1689 applies obligations in phases. A hardware vendor is not a provider of an AI system by virtue of selling compute, but may be in scope where it supplies a system placed on the market under its own name.
The proposed Cloud and AI Development Act would tie public-sector cloud procurement to Union assurance levels. It is a proposal and has not been adopted.
FCC Part 15 governs unintentional radiators. Equipment intended for a residential environment is subject to the stricter Class B emissions limits.
Equipment placed into a US workplace is expected to carry a listing from an OSHA-recognised Nationally Recognized Testing Laboratory, typically against UL 62368-1.
The FCC's US Cyber Trust Mark is a voluntary labelling program for consumer connected devices.
The FTC Green Guides govern environmental marketing claims in the United States. Unqualified general environmental benefit claims are treated as deceptive.
A TPM proves what was loaded. A TEE proves what is running and protects it while it runs. Hardware with a TPM and no confidential-computing capability is not a trusted execution environment and is never described as one.
Not cited anywhere in the site’s copy. Listed here because they bear on decisions a buyer in this market has to make.
Whether a product falls into a CRA importance class — and therefore loses the self-assessment route — depends on the functions it ships. A delivered hypervisor or container runtime is a classification question, not a marketing one.
Per-SKU classification must be settled with counsel before any conformity claim is published.
An amending regulation adjusting the AI Act's application timeline has been reported. The exact Official Journal citation must be confirmed before it is referenced in writing.
Regulation (EU) 2019/424 sets ecodesign requirements for servers and data storage products. The status of its successor instrument, including any parts-pairing provisions, is unconfirmed.
Several US states apply large-load interconnection procedures and reporting duties above thresholds in the tens of megawatts. Thresholds vary by state and utility and must be cited per jurisdiction.
A range was reported in secondary sources. No specific figure is quoted on this site until each state's tariff has been read directly.
US export controls applicable to advanced computing hardware have changed repeatedly. The current posture, and the correct classification per SKU, must be confirmed before any shipment or published availability.
