CoreWeave Puts Most of 22.5 MW Online in Copenhagen

CoreWeave said on Oct. 27 that most of a planned 22.5 megawatts of IT capacity is online at atNorth's DEN01 data center in Copenhagen, the company's first deployment in Denmark.

The hall runs NVIDIA Blackwell systems linked by NVIDIA Quantum-X800 InfiniBand, CoreWeave said. DEN01 has an agreement to send surplus heat into the local district-heating network. The company said the site brings its European footprint to nine data centers across five countries: the United Kingdom, Spain, Sweden, Norway and Denmark.

The 22.5 MW figure is IT capacity inside a colocation hall, not a new utility interconnection filed in this release. CoreWeave said it operated 51 data centers and more than 1.5 gigawatts of active power as of June 30, 2026, and that contracted power stood at about 4.2 gigawatts as of its Aug. 11, 2026 earnings call. The release does not say the Copenhagen hall sits inside that contracted total, or that it was added on top of it. The release says the majority of the 22.5 MW is online and does not split live megawatts from the rest.

On Oct. 22, Voltgrid reported that NVIDIA's Jensen Huang described neocloud demand as extremely strong and capital as scarce. The Copenhagen notice adds a dated megawatt figure to that demand, at a site that is already partly in service.

A private network timed to mid-2027

CoreWeave is adding points of presence in the United Arab Emirates, India, Indonesia, Singapore, Australia, Korea and Japan. It said the build starts later in the fourth quarter of 2026 and reaches a full loop in mid-2027, extending a backbone it already runs in North America and Europe onto four continents. Each new point is planned to carry several 400 gigabit-per-second links, with hardware MACsec encryption and redundant paths. The company calls the backbone petabit-scale. That label is CoreWeave's own description. The release does not publish a measured traffic total.

atNorth chief executive Eyjólfur Magnús Kristinsson said the partnership gives CoreWeave a hall built for GPU-heavy work, and that the operator backs renewable generation through power purchase agreements while sending heat to nearby homes. The release names no power-purchase counterparty, no contracted megawatts and no date for when the heat supply starts.

What is not confirmed yet

The release gives no GPU count for DEN01, and it does not say how many of the 22.5 MW are serving customers today. Heat reuse and renewable-power agreements are described as arrangements, not as commissioned megawatts. atNorth operates the building. CoreWeave pointed to earlier capacity news in Indonesia and India without restating those megawatts in this notice.
