The Blackwell-powered installation adds European computing capacity at a site with an agreement to supply surplus heat to district heating.
Listen to this story
CoreWeave’s Copenhagen site is its first deployment in Denmark and expands its European footprint to nine data centers across five countries. At atNorth’s DEN01 facility, most—but not all—of the planned 22.5 MW of IT capacity was online when the company announced the deployment on October 27, 2026. The build adds GPU capacity using NVIDIA Blackwell systems and a Quantum-X800 InfiniBand fabric; it also pairs compute expansion with a district-heating heat-reuse arrangement, though the environmental benefits described are stated aims rather than reported results.
Denmark joins CoreWeave’s existing European markets in the United Kingdom, Spain, Sweden and Norway.
CoreWeave reported 51 operating data centers and more than 1.5 GW of active power globally as of June 30, 2026.
The company separately cited about 4.2 GW of contracted power on its August 11 earnings call, distinct from active power.
CoreWeave’s first Denmark deployment is operating in Copenhagen, adding AI computing capacity to its European infrastructure. On October 27, 2026, the company said most of its planned 22.5 megawatts of IT capacity was online at atNorth’s DEN01 data center. The opening gives CoreWeave a presence in a fifth European country.
DEN01 uses NVIDIA Blackwell systems connected through NVIDIA Quantum-X800 InfiniBand. Blackwell supplies the computing systems, while InfiniBand provides the network connecting them. atNorth CEO Eyjólfur Magnús Kristinsson described the facility as designed for GPU-intensive processing—the chip-heavy computing used for AI workloads.
The Copenhagen deployment brings CoreWeave’s European footprint to nine data centers across five countries. Denmark joins the United Kingdom, Spain, Sweden and Norway, extending the company’s regional presence through capacity housed at a Nordic data-center operator’s facility.
DEN01 also has a heat-reuse agreement to supply surplus heat to the district heating network. The arrangement gives heat from the computing facility a use beyond the data center itself. CoreWeave describes it as a way to reduce reliance on alternative heating sources.
Kristinsson linked the partnership to renewable energy development through power purchase agreements and to warming local homes through heat reuse. His case for DEN01 combines infrastructure built for demanding computing jobs with energy efficiency and local heating benefits. Those environmental benefits are the operator’s stated aims.
The Denmark deployment sits within a much larger global operation. CoreWeave cited 51 operating data centers worldwide and more than 1.5 gigawatts of active power as of June 30, 2026. It separately cited approximately 4.2 gigawatts of contracted power as of its August 11 earnings call, showing the scale of its power commitments alongside its operating infrastructure.
