Denmark is navigating the integration of data centers into its national energy infrastructure. Initially, reports indicated that most of the country’s approximately 50 data centers were releasing surplus heat into the air rather than utilizing it for district heating or industrial processes. Barriers to heat utilization included taxes, price cap regulations, and infrastructure investment limitations. For example, an Apple facility near Viborg has been unable to effectively provide heat due to these regulations, despite the potential for significant long-term savings.

More recently, the Danish government has announced plans to expand data center capacity to 18.4 GW by 2035. The strategic goal is to transform these facilities into ‘energy prosumers’ that contribute to grid stabilization and the renewable energy ecosystem. This expansion coincides with Denmark’s broader energy transition, where wind power has become a dominant source of domestic electricity production.

## Timeline

### 2026-08-20: Denmark expands data center capacity and wind energy share

Denmark is expanding its data center capacity to 18.4 GW by 2035 while wind energy accounted for roughly 60% of its domestic electricity production in 2025.

### 2026-08-15: Danish data centers struggle to utilize surplus heat

Few Danish data centers utilize surplus heat for district heating due to investment barriers and previous price caps, despite significant potential for energy savings and resource efficiency.
