EU mandates data centre energy and water efficiency disclosures

The European Commission published a Delegated Regulation establishing a common Union rating scheme for data centres, according to energy.ec.europa.eu. Reuters reported that the rules will require data centres to disclose energy and water efficiency figures, giving grid operators and regulators a standardised view of load quality across the EU.

The timing matters for power-market participants. AI data centre capacity additions are accelerating in multiple European bidding zones, and the absence of comparable efficiency data has complicated PPA structuring and grid-connection prioritisation. A common rating scheme changes that baseline.

Separately, Recharge News notes that AI data centre developers are increasingly siting capacity where power is cheap and plentiful, a dynamic that intersects with wind-rich zones in northern Europe. Whether the new disclosure framework accelerates or complicates those siting decisions will be a key question for asset managers with wind and storage exposure.
