Editorial note: Europe's five core data center markets added 194 megawatts of new capacity in the first half of 2026, though not evenly. Paris alone accounted for 72.5 MW, while Dublin managed just 11.4. This roundup covers the week of August 3 to 10, 2026, and if it's being republished on a regular schedule, every figure below should be checked against current sources first, since that's the whole point of a "this week" post.Ireland: grid policy is reshaping who can build
Ireland: Grid Policy Is Reshaping Who Can Build
Ireland's Large Energy User Action Plan has been in effect since March 31, 2026, and it requires any operator seeking a new grid connection to show it can match at least 80 percent of its power demand with new renewable projects built inside Ireland itself. Data centers made up 22 percent of Ireland's electricity use in 2025, and an Irish High Court case is currently challenging whether rules permitting gas powered backup generation at connected sites actually comply with EU law.
Netherlands: Still Restricted, But Finding Workarounds
A Dutch government decree from January 2024, limiting new hyperscale data centers to two remote northern municipalities, is still in force. Rather than fight it, some developers are building around it. In July 2026, the Municipality of Uithoorn reached an agreement with Switch Datacenters and a group of local greenhouse growers to send the facility's waste heat directly into greenhouse heating systems nearby.
Spain: New AI Campuses Betting on Their Own Power
In central Spain, a 3 billion euro AI campus backed by EdgeMode, BlackBerry AIF, and the town of Mora is moving through regional permitting. It shares a strategy with several other projects in the region right now: build the power source first, rather than wait in a grid connection queue that could take years.
Germany: A National Strategy, and Real Compliance Deadlines
Germany's National Data Centre Strategy launched in March 2026 with a target of doubling national capacity by 2030. Existing facilities now have to hit a Power Usage Effectiveness rating of 1.5 by July 2027 and 1.3 by 2030. Maincubes' 40MW facility in Dietzenbach is one of the first built to meet the new heat reuse rules, and the Argaman Group's 200MW project in Birstein runs on its own dedicated wind farm rather than the public grid.
The Bigger Picture: Where Capacity Actually Landed in H1 2026
JLL's mid year EMEA report shows exactly how uneven that 194 MW of new capacity was. Paris led at 72.5 MW, London added 49 MW, Frankfurt 45 MW, Amsterdam 16.3 MW, and Dublin trailed at just 11.4 MW, a fairly stark illustration of how much Ireland's grid restrictions are slowing delivery compared to the rest of the FLAP-D group.
Public Pushback Is Part of the Story Now
Stack Infrastructure pulled a proposed project out of Babenhausen, Germany, after the city council pushed back and demanded more transparency, echoing what happened to Meta's planned facility in Zeewolde, Netherlands, back in 2022. For anyone working in site selection or construction in this industry, dealing with local pushback is now just part of the job.
