Data center policies in the EU

As data centers are projected to account for more than 3% of the European Union's (EU) total electricity demand by 2030, the EU is developing a sustainability rating scheme for data centers under the recently revised Energy Efficiency Directive.

With the technologies available today, the data center sector can continue to grow in the age of AI, while at the same time save energy, for themselves and other externally, and comply with the new regulatory requirements in the EED. Danfoss can support data center operators and owners in this transition.

Reporting requirements

Data centers with IT power demand of or greater than 500 kW must report annually the data on their energy performance and the key sustainability indicators Power Usage Effectiveness (PUE), Water Usage Effectiveness (WUE), Energy Reuse Factor (ERF) and Renewable Energy Factor (REF).

Heat Recovery

- - - - Data centers with IT power demand of > 1 MW should follow the best practices in the most recent version of the European Code of Conduct on Data Centre Energy Efficiency, such as the recovery of excess heat and the location of data centers where excess heat can be reused.
      - Data centers with IT power demand > 1MW shall utilize the excess heat or other excess heat recovery applications where technically and economically feasible.
      - Member States shall also ensure regional and local authorities develop local heating and cooling plans for municipalities with populations exceeding 45,000. These plans must be grounded in comprehensive national heating and cooling assessments and focus on enhancing energy efficiency, including via the recovery of waste heat. This presents a significant opportunity for data centers situated near communities, where excess heat can be effectively utilized for productive purposes.

Upcoming policy developments

- - - - With the goal to establish a sustainability rating scheme, the European Commission will, based on the data reported, assess the feasibility of introducing minimum performance standards and the transition towards net-zero emission data centers.
