Denmark Halts New Data Center Grid Connections as Power Demand Outpaces Supply

Denmark has become the first Nordic country to confront its data center energy crisis head-on, after the nation's state-owned grid operator introduced a temporary freeze on new grid connection agreements following what officials described as an "explosion" in capacity requests.

Energinet, the Danish grid operator, enacted the pause in March, citing a backlog of roughly 60 GW of projects awaiting connections — a figure that dwarfs Denmark's peak electricity demand of approximately 7 GW. Data centers alone account for nearly a quarter of that queue, representing 14 GW of pending requests.

The freeze is scheduled to last three months, or until Energinet can complete an overview of the situation and implement new measures to expand capacity. Industry insiders, however, say an extension cannot be ruled out.

"We have to be realistic and look at what is actually available. It's not possible to really just go berserk with all kinds of connection agreements, because the power is not available," Henrik Hansen, CEO of the Data Center Industry Association (DDI), told CNBC. Hansen added that the surge in applications has created a "fantasy" queue, and called on the industry to apply stricter criteria to determine which projects deserve the fastest connections.

"We argue very much for the need to clean up that queue and look into stronger criteria in terms of maturity, actual investment decisions, customers and also the societal value," Hansen said.

The timing is complicated by domestic politics. Denmark is in the process of forming a new government following a general election, and no formal policy decisions have been made. The energy and climate ministry declined to comment. Prior to the election, Energy Minister Lars Aagaard signaled he would explore giving Danish customers priority grid access, effectively pushing data centers toward the back of the line. "I suspect that data centers and battery parks, among other things, are taking up much of the available capacity in the electricity grid," Aagaard told business news outlet Finans in January.

The stakes for the data center industry are significant. Denmark had approximately 398 MW of installed data center capacity in 2026, with an additional 208 MW under construction, according to the DDI Association. That figure is projected to grow by 1.2 GW by 2030, with hyperscalers currently representing 60% of existing capacity.

Operators from major technology companies made clear at the Data Centers Denmark conference in Copenhagen last week that regulatory uncertainty translates directly into capital flight. "You can only wait so long," Diana Hodnett, global director of data center public affairs, partnerships and economic development at Google, told CNBC. She noted that when the outcome of a moratorium is unclear, companies pivot immediately to other markets. "I'm not sure governments and TSOs realize how quickly that can happen," Hodnett added.

Pernille Hoffmann, managing director of the Nordics at Digital Realty, framed the risk plainly: "If you cannot get your AI workloads located in Denmark, you'll just move them somewhere else, and that is what we will see."

The debate is unfolding across Europe. The Netherlands and Ireland are the only two European countries to have enforced full moratoriums on data centers, though both have since eased restrictions under certain conditions. Grid pressures are nonetheless spreading continent-wide, as AI-driven demand compounds an electrification trend already accelerated by the energy transition and broader digitalization.

Sebastian Schwartz Bøtcher, country sales director at Schneider Electric, described the situation on LinkedIn as the "energy policy hunger games," warning against singling out specific industries. Tobias Johan Sørensen, a senior analyst at think tank Concito, echoed that view, arguing for differentiated queues based on a clear set of criteria rather than outright exclusions.

How Denmark resolves the tension between grid constraints and its ambitions as a data center hub will likely be watched closely by other Nordic nations still weighing their own responses to surging energy demand.
