EU Mandates Energy and Water Disclosure for Data Centres over 500 kW
The European Commission proposes rules forcing large data centres to report resource usage, targeting 114 TWh in consumption by 2030.
Key points
- EU proposes mandatory energy and water disclosure for data centres exceeding 500 kW capacity to manage AI-driven demand.
- Data-centre electricity use is projected to rise from 68 TWh in 2024 to 114 TWh by 2030, exceeding 3% of total EU consumption.
- The regulation uses a rating system for transparency rather than hard caps, with disclosures required starting next year.
The European Commission has proposed a regulatory framework requiring data centres with power capacity exceeding 500 kW to disclose their energy and water consumption. This measure aims to manage grid strain and resource depletion as artificial intelligence workloads drive a surge in facility demand across the bloc.
According to reports from digitaltoday.co.kr, the proposal introduces a common rating system to benchmark operational efficiency. The initiative is not designed to cap absolute usage but to ensure transparency and sustainable integration into local energy systems, addressing the environmental impact of rapid AI infrastructure expansion.
Projected consumption surge to 114 TWh
EU data-centre electricity consumption reached 68 TWh in 2024, a figure expected to rise to 114 TWh by 2030 under International Energy Agency forecasts. This increase, driven largely by AI computing infrastructure, would account for more than 3 percent of the EU's total electricity consumption, highlighting the critical need for efficiency metrics.
The European Commission plans to triple data-centre capacity within seven years to strengthen digital sovereignty. However, this expansion creates a dual challenge: maintaining competitiveness in AI while preventing excessive strain on power grids and water supplies, particularly in regions facing water scarcity.
Rating system replaces hard usage caps
Rather than imposing immediate limits on electricity or water use, the proposal focuses on transparency. Operators must disclose resource usage, including water consumption linked to local scarcity levels and contributions to local energy ecosystems, such as waste-heat reuse for district heating.
The new rating system functions similarly to energy-efficiency labels for appliances, providing a standardized benchmark for comparing facility performance. This approach allows the EU to monitor efficiency gains without stifling the necessary expansion of digital infrastructure required for economic growth.
Consultation begins for 2026 implementation
A two-month consultation process has commenced, allowing the European Parliament and the Council of the European Union to review the proposed rules. If the legislative process proceeds as planned, data centres will be required to disclose sustainability-related ratings starting next year.
The rating system is expected to serve as a foundation for future minimum performance standards. As AI infrastructure continues to expand, these disclosures will likely inform stricter regulations on resource use, forcing operators to improve water efficiency and integrate more deeply with sustainable energy practices.
