Grid access is becoming the scarce resource — and Denmark is earlier in the curve than it looks
Auxilium Infrastructure Partners’ perspective on why network capacity, not generation, is becoming the binding constraint of the energy transition — and what that changes for where assets get built.
The energy transition is usually described as a race to build more renewable generation. That description is no longer complete. The more consequential contest is for something less visible and far harder to manufacture: access to the network that carries the power. For most of the sector’s history the working assumption was simple — if a project needed electricity, the grid would eventually deliver it. That assumption is now breaking down.
Earlier this year Energinet paused new transmission-level connection agreements as requests reached levels the system had never seen. The reaction across the Danish market was immediate, and the underlying question was the right one: how much capacity is actually available? It is tempting to read the pause as a Danish administrative event. It is better read as a local instance of a European pattern.
The scarcity has moved
The premise that organised energy policy for a generation — electricity is scarce, so build more of it — has quietly inverted. Generation is increasingly abundant; network capacity is not. And almost every component of the transition now competes for the same constrained resource: battery storage, data centres, EV charging, industrial electrification, heat pumps and district heating, Power-to-X, and new renewable generation itself. Each case is sound in isolation. Together they are bidding for a fixed pool of grid capacity. The scarcity has moved from the electrons to the connection — a subtle distinction with profound consequences.
Denmark does not have to imagine where this leads
Two larger markets are already further along. In the Netherlands — Europe’s clearest case of congestion — businesses in several regions now wait years for a new connection, industrial expansion has been deferred, and investment decisions increasingly turn on network access rather than capital. The Dutch position did not arrive overnight; it accumulated as electrification outpaced grid expansion, and was structural before it was widely visible.
The United Kingdom tells the complementary story: a connection queue that grew to many times the network’s capacity, clogged with projects that would never be built but still held their place ahead of mature ones. The response was to stop allocating access first-come, first-served and start weighting project maturity, readiness, and system value. That logic is now spreading across Europe — Denmark included.
The end of “connect everything”
This is the real content of the Energinet discussion. For decades the sector assumed every viable project could eventually connect if its developer waited long enough. That assumption fails once requested capacity runs well ahead of available capacity. Operators and policymakers are then forced into questions they could previously avoid: which projects create the most value for society, which strengthen system stability, and which are mature enough to justify scarce capacity. Those questions will not recede. They will define allocation as electrification accelerates.
Existing connections are repricing
The first-order consequence is that existing electrical infrastructure is becoming a strategic asset. Across Europe, developers are favouring industrial sites with connections already in place over greenfield sites that require reinforcement, for the simple reason that an existing connection can shorten delivery by years. Established high-voltage links, substations, industrial zoning, a documented consumption history, access roads — attributes once treated as operational convenience — are becoming strategic advantages. In some cases the connection is worth more than the land beneath it.
Flexibility, not just more steel
More network will be built, and it is needed. But reinforcement alone cannot close the gap on the timeline the transition requires; flexibility has to carry part of the load. Battery storage absorbs surplus generation, reduces curtailment, supports local balancing, and defers expensive upgrades. Industrial flexibility — electric boilers, thermal storage, cooling, controllable processes — does the same from the demand side. The future system will not simply be larger. It will need to be smarter, and optimising what already exists may matter as much as building what does not.
A fourth factor
For decades, energy developers focused on securing land, permits and financing. Increasingly, a fourth factor sits alongside them: access to the grid. Investors are pricing connection risk next to financial risk. Industrial companies are incorporating grid availability into site-selection decisions. Developers are prioritising locations where infrastructure already exists.
The pause announced by Energinet should therefore not be viewed as an administrative footnote. It is an early indication of a broader structural shift already visible elsewhere in Europe. The defining constraint of the next phase of the energy transition may not be our ability to generate renewable electricity. It may be our ability to move it to where it is needed.
At Auxilium Infrastructure Partners, we continuously engage with these dynamics in both development and operations across DK1 and DK2. We are always interested in discussing our perspective with investors and partners navigating this transition.
