Denmark’s electricity grid is under unprecedented pressure. So much so that Energinet — the state-owned company responsible for the country’s transmission network — has temporarily paused all new grid connection applications. But while many might instinctively point the finger at
electric vehicles, the data tells a very different story.
The Real Culprits: Data Centers, Battery Parks, and Power-to-X
The applications currently queuing up at Energinet represent a staggering combined demand of around
60 gigawatts of electricity. For context, Denmark’s current peak consumption sits at roughly
7 gigawatts. In other words, if every pending project were approved and built, Denmark’s electricity consumption would be
eight times larger than it is today.
The grid simply cannot handle that. As a result, Energinet has pressed what it internally calls the “big red button” — a three-month pause while the company analyses the situation and looks for solutions.
The projects driving this surge are not household EV chargers. They are
large-scale data centers, grid-scale battery storage facilities, and Power-to-X plants — installations that convert electricity into hydrogen or synthetic fuels. Each of these individually consumes vastly more power than entire neighborhoods of electric vehicles. The electrification of transport, by comparison, accounts for only a small share of the overall pressure on the grid.
A Grid Built for Another Era
The underlying problem is structural. Europe’s electricity infrastructure was designed for a different energy reality — one where consumption grew slowly and predictably. Today, societies are simultaneously trying to electrify industry, transport, and energy production itself. That is creating an entirely new kind of demand, and the grid was never built for it.
“Energinet is already building a lot of grid infrastructure, and we have more projects underway than ever before. But we need to build more — and we need to do it faster.”
Kim Willerslev Jakobsen, Director of System Operations at Energinet
He added that electricity demand is simply growing faster than the infrastructure can keep up with, forcing the company to make quicker investment decisions and prioritize more sharply than before.
An Emergency Package in the Works
To relieve pressure in the short term, Energinet is developing an emergency package aimed at unlocking additional capacity. The plan includes:
- Accelerating investment decisions on new grid infrastructure
- Deploying technical solutions to increase throughput in existing cables
- Introducing stricter prioritization of which projects gain grid access first
New high-capacity transmission lines — effectively electricity motorways — are already under construction across the country, but expanding grid capacity at the pace the new energy landscape demands can take many years.
A Europe-Wide Problem
Denmark is far from alone. Across
Europe, grid operators are facing similarly long queues of projects seeking connection. It is a sign that electrification is accelerating faster than anyone anticipated — and that the infrastructure race to keep up has only just begun.
