Energinet, Denmark's transmission system operator, extended its pause on new large-load connection agreements on Wednesday 27 May, prolonging a hold first imposed in March. The decision keeps fresh data-centre hook-ups frozen in one of Europe's cleanest and most wind-rich grids. 1
The extension matters because it disproves a comfortable assumption. One theory held that US moratoriums and British queues would simply push demand toward countries with renewable surpluses to spare. Denmark has exactly that surplus and still cannot connect the load. The constraint is not generation mix but the pace at which any transmission network can physically be built out to carry new demand. Surplus wind does not help if the wires cannot move it to where the compute sits.
The scale of the backlog explains the freeze. Energinet is sitting on a connection queue of roughly 60 GW against national peak demand of about 7 GW, with data centres making up around 14 GW of that pipeline. At that volume the queue itself becomes the bottleneck: the operator cannot assess applications fast enough regardless of any intent to approve them.
The same dynamic has now surfaced across very different jurisdictions. Johor in Malaysia halted approvals after the country's first water-rights protest , a grid-and-resource ceiling reached despite no shortage of political will to build. Clean or not, the grid grows at the speed it grows, and the compute boom is arriving faster.
