Why Power, Not Space, Now Decides Data Centre Deals
Short answer: because grid connection has become slower than construction. In Europe's core hubs, connection queues now run substantially longer than the one-to-two years it takes to build the facility itself. A site without credible, dated power is not deliverable capacity, whatever its floor area. Any serious capacity search — on either side of the table — has to be run on time-to-power, not square metres.
The structural inversion
The International Energy Agency's published analysis of the European market sets out the position plainly: while a data centre typically takes one to two years to build, expanding the electricity infrastructure behind it takes considerably longer. Within the European Union, grid connection wait times range from roughly two to ten years depending on the country, and in the established FLAP-D hubs — Frankfurt, London, Amsterdam, Paris, Dublin — developers face queues averaging seven to ten years.
The European Union Agency for the Cooperation of Energy Regulators has put direct grid congestion costs at around EUR 4.3 billion in 2024, before any account is taken of the indirect cost of delayed projects.
This is an inversion of how the sector has historically worked. The building used to be the long pole. Now the connection is.
What it changes commercially
Power-secured sites carry a premium.
Certainty of energisation has become a pricing input in its own right. A site with a firm, dated connection is a materially different asset from a site with an application in a queue, even where the two look identical on paper.
Speculative land is being repriced.
Where a site has no credible route to power inside a usable window, the market increasingly treats it as optionality rather than capacity.
Capital is relocating.
Developers and investors are moving toward markets with genuine grid headroom — the Nordics, Iberia, Italy, and a widening set of secondary and emerging markets — rather than waiting out a queue in a saturated hub.
Regulators are intervening.
In the United Kingdom, Ofgem has moved away from strict first-come-first-served allocation toward a first-ready approach that prioritises projects holding land, financing and permits. Comparable reforms are under discussion elsewhere in Europe. These are real changes, but existing queues will take years to unwind, and reform does not add megawatts.
Efficiency rules are becoming gating conditions.
Reporting obligations under the EU Energy Efficiency Directive are now live, and national regimes have gone further — Germany applies a hard power usage effectiveness ceiling of 1.2 for facilities commissioned after 30 June 2026, alongside an escalating energy-reuse requirement. Elsewhere, proposals would tie efficiency compliance directly to the grant and retention of grid access. Efficiency is no longer only a sustainability question. It is increasingly a permission question.
The questions that actually matter
Whether you are seeking capacity or offering it, these are the questions that separate deliverable capacity from a plan:
Is the power energised, contracted, or applied for? Those are three different states, not three ways of saying the same thing.
What is the dated connection milestone, and who is the counterparty to it?
What is the rack density ceiling in practice, given the installed cooling design?
What behind-the-meter or on-site generation exists, and on what terms?
What efficiency and reporting obligations attach in this jurisdiction, and does the facility currently satisfy them?
What happens to the timeline if the connection slips — is there a fallback site or a phased alternative?
A requirement or an offer that cannot answer these is not yet ready to go to market.
Frequently asked questions
Does this mean nothing can be delivered in the core hubs?
No. It means near-term availability in those hubs is largely existing capacity being re-let or re-phased, rather than new build. That capacity exists — it is simply not advertised.
Are secondary markets a compromise?
Not necessarily. For many workloads, deliverable power in an available market is worth more than a queue position in a prestige one. It depends entirely on latency, sovereignty and interconnection requirements.
How does this affect the way you run a search?
We screen on time-to-power first. A site that cannot evidence a credible energisation date does not go onto a shortlist we put in front of a client.
