European Commission Proposes Energy Rating Scheme for Data Centres

This initiative aims to enhance energy efficiency in data centres, which are projected to consume a significant portion of the EU's electricity by 2030.

• On September 21, 2026, the European Commission proposed a common energy rating scheme for data centres with IT power demand exceeding 500 kW.
• The scheme mandates transparency in energy and water consumption, waste heat reuse, and clean energy integration.
• Labels are expected to be introduced in 2027, following a two-month scrutiny period by the European Parliament and Council.

• Data centres are projected to triple in capacity over the next five to seven years, driven by rising AI demand.
• Electricity consumption by EU data centres is expected to reach 114 TWh annually by 2030, accounting for 3% of total EU electricity use.
• This proposal builds on previous regulations aimed at improving energy efficiency and reducing carbon emissions in the digital sector.

The European Commission's proposal for a common energy rating scheme for data centres is a strategic response to the escalating demand for digital services, particularly those driven by artificial intelligence. As data centres are projected to triple in capacity over the next few years, their energy consumption is expected to soar to 114 TWh annually by 2030. This represents a significant increase from 68 TWh in 2024, highlighting the urgent need for regulatory measures to ensure that this growth does not come at the expense of energy efficiency and sustainability.

The new scheme targets data centres with an installed IT power demand exceeding 500 kW, requiring them to disclose metrics related to energy and water efficiency, waste heat reuse potential, and contributions to grid flexibility. By establishing a standardized rating system, the European Commission aims to enhance transparency and accountability within the sector. The introduction of electronic A-to-G style labels will provide a clear benchmark for operators, investors, and consumers, facilitating informed decision-making.

This initiative is part of a broader effort to align the EU's digital sovereignty goals with its energy transition objectives. By promoting sustainable practices in data centre operations, the Commission hopes to mitigate the environmental impact of the digital economy while ensuring that the energy grid remains stable and resilient. The emphasis on transparency is seen as a foundational step toward driving efficiency improvements across the sector.

The proposal also comes in the wake of previous regulatory efforts, including the recast Energy Efficiency Directive and earlier delegated regulations that established reporting obligations for data centres. These prior steps laid the groundwork for the current initiative, which is expected to culminate in the introduction of minimum performance standards legislation in Q2 2027.

As the EU moves forward with this proposal, market participants are likely to experience increased scrutiny regarding efficiency metrics in site selection and operational practices. The anticipated labels will not only serve as a tool for compliance but also as a competitive differentiator in an increasingly sustainability-conscious market.

• Data Centre Operators: Must adapt to new reporting requirements and improve energy efficiency to meet compliance standards.
• Investors: Will need to reassess investment strategies based on the sustainability metrics of data centre operations.
• Energy Providers: May experience shifts in demand patterns as data centres optimize their energy consumption.
• Regulatory Bodies: Will oversee the implementation and enforcement of the new rating scheme, impacting their operational focus.
• Multinational Corporations: Could influence global supply chains and procurement criteria based on EU standards.

• Implementation Timeline: Monitor the progress of the scrutiny period and the introduction of labels in 2027, as this will set the stage for compliance expectations.
• Market Reactions: Watch for shifts in site selection and operational practices among data centre operators as they adapt to new efficiency metrics.
• Legislative Developments: Keep an eye on the planned minimum performance standards legislation expected in Q2 2027, which could further impact operational requirements.
