The European Commission has proposed energy and water efficiency ratings for data centres above 500 kW. Operators would also report their relationship to local water stress and ability to reuse waste heat. The proposal does not impose consumption caps, but it begins turning resource efficiency into a comparable procurement metric.
- Scope: individual data centres above 500 kW
- EU data-centre capacity: 12 GW in 2025, projected 28 GW in 2030
- Current share of EU electricity demand: about 2.5%
- EU countries and lawmakers have two months to object
What is—and is not—decided
The proposal focuses on transparency and a common rating scheme. It does not yet cap energy or water use or require publication of total power consumption. Accumulated ratings, however, could inform future minimum standards, permits and procurement policies.
How component RFQs may change
Contact resistance and heat from busbars, connectors and terminals contribute to facility efficiency. Buyers may request long-term power-loss and temperature-rise data.
Heat exchangers and cooling components may need to prove leakage control, corrosion resistance, water efficiency and waste-heat compatibility.
Suppliers able to provide material origin, recycled content, product-emissions data and lot traceability are likely to be better positioned in European projects.
Action checklist
- Establish baseline data for resistance, power loss, heat and cooling performance.
- Compare efficiency and corrosion performance before and after material or plating changes.
- Translate part life and electricity savings into total cost.
- Add environmental and traceability data to English RFQ packages.
- Monitor the objection period and any future minimum-efficiency rules.
BIZPECTRA view
The proposal does not directly regulate component makers. But once operators are ranked by efficiency, pressure will move into power, connector and cooling supply chains. Korean suppliers should add quantified loss and environmental data to proven quality and fast delivery.

Downstream RFQ effects are BIZPECTRA's inference from the proposal and established global procurement practice.
Material optimisation and Ni/Ag/Sn/Au selective plating can reduce contact resistance, heat and precious-metal use while protecting reliability.
