Germany Moves to Ease Data Center Heat Recycling Rules to Boost AI Infrastructure

The German federal government has approved an amendment to relax strict regulations imposed on new data centers under the Energy Efficiency Act passed in 2023. The original law required all new data centers to recycle a portion of the waste heat generated by their computer equipment, ideally into nearby municipal heating systems. However, according to WIRED, this requirement was criticized by the industry as a 'data center prevention act,' leading to the cancellation of several large projects.

Under the amended bill, soon to be submitted to the German parliament for ratification, data center operators will no longer be obligated to reuse waste heat but only to assess its technical and economic feasibility; they are exempt if it is not feasible. Katherina Reiche, Germany's Federal Minister for Economic Affairs and Energy, stated that this move aims to create conditions for digital sovereignty and economic growth. Previously, Stack Infrastructure canceled a $3 billion data center project in Hesse due to compliance difficulties, and state-owned Komm.ONE withdrew from a project in Baden-Württemberg.

This policy shift reflects the difficult trade-off between AI ambitions and climate commitments across Europe. Germany plans to double the scale of its data center fleet and quadruple the amount of compute available for running AI models by 2030, aiming to reduce dependence on US AI technology. However, EU member states have committed to cutting greenhouse gas emissions by 55 percent by the end of the decade. Patrick Graichen, a former senior official at Germany's Ministry for Economic Affairs and Energy, criticized the government for sacrificing climate targets to ride the AI wave.
