TL;DRThe European Commission is asking households to cut peak electricity use as AI data centres strain grids, while publishing a Data Centre Energy Efficiency Package with ratings and minimum performance standards. Ireland’s data centres already consume 22% of national electricity, and regional bills could rise 20-40%.
The European Commission has called on households across the bloc to reduce electricity consumption during peak hours, citing the rapid growth of AI data centres, accelerating electrification, and rising overall digital infrastructure demand as factors straining European power grids. The Commission simultaneously published a Data Centre Energy Efficiency Package on 3 June that introduces a rating scheme for data centres in Europe, assesses data submitted under existing reporting requirements, and launches work on minimum performance standards.
The message to consumers is awkward: Europe is racing to build AI infrastructure to avoid falling behind the US and China, but the electricity required to power that infrastructure is competing directly with household demand. US utilities plan to spend $1.4 trillion by 2030 on grid upgrades to meet AI-driven electricity demand, and Europe faces the same fundamental challenge with tighter grid capacity and higher baseline energy prices.
