Directive (EU) 2023/1791 recast in October 2023. Article 12 introduces obligations specific to data centres above 500 kW IT installed power: mandatory reporting of energy performance and sustainability indicators (PUE, WUE, ERF, REF), with the Commission's first-phase Union rating scheme adopted under Delegated Regulation 2024/1364, second-stage rating in feedback consultation since March 2026, and the Q3 2026 Data Centre Energy Efficiency Package expected to include second-stage rating plus minimum-performance-standards work.

What are the specific PUE thresholds under EED?

The EED reporting itself does not set thresholds; it requires reporting. Thresholds come through the rating scheme (in force at first-phase; second-stage under consultation) and potentially through minimum performance standards (in preparatory work). Singapore DC-CFA2 already sets a threshold: PUE ≤ 1.25 at 100% IT load.

Is Singapore DC-CFA2 an allocation gate or reporting requirement?

An allocation gate. Singapore is not merely regulating equipment efficiency; it is rationing scarce data-centre capacity through an efficiency criterion. IMDA awards specific allocation slots against DC-CFA2 criteria including PUE ≤ 1.25, green-energy sourcing and IT-efficiency requirements.

Which US states have the tightest data-centre efficiency frameworks?

Virginia (SCC + locality permitting), Oregon (PUC + utility service territory conditions) and California (CEC + CPUC + Title 24) have the tighter current frameworks. Arizona has water-use pressure. Texas is comparatively less efficiency-focused. US frameworks are heterogeneous, not converging on a common Singapore-style gate.

Which vendors are best positioned for EED-driven vendor selection?

European incumbents with mature high-efficiency portfolios (Schneider Electric with Galaxy + EcoStruxure, ABB Electrification) lead. Non-European vendors compete through EU subsidiaries (Vertiv, Eaton). Delta Electronics is growing EU share with high-efficiency UPS + 800V DC power-rack capability.

EU EED, Singapore DC-CFA2 and the US state read-across: efficiency as procurement constraint

29 August 2026 · 22 min read

EU EED, Singapore DC-CFA2, US state read-across. Regulatory ladder REPORT > RATE > PROCURE > STANDARDISE > EXCLUDE. Efficiency becomes procurement constraint. — Efficiency is migrating from ESG preference to procurement constraint. EU EED reporting → rating → minimum standards; Singapore DC-CFA2 allocation gate; US state mosaic.
