Summary
- UNIQ LAND is proposing a 150MW data centre campus near Langenhorn in Schleswig-Holstein, with possible expansion to 300MW connection capacity.
- Local residents have challenged the project’s scale, building height, and transparency during the planning process.
- Renewable-rich siting does not remove the need for public consent, land-use clarity, and a regional data centre strategy.
UNIQ LAND Development is proposing a 150MW data centre campus near Langenhorn in North Frisia, Schleswig-Holstein, in a project that has drawn local resistance before municipal planning permission has been granted.
The proposal covers a site near Sikkeackerweg and has been reported as a 55,000m² development with potential to expand grid capacity to 300MW. Construction has been described as possible from March 2028, subject to approval.
The site is being promoted around Schleswig-Holstein’s strong renewable energy position, particularly wind generation. UNIQ LAND’s managing director, Jens Kampkötter, has linked the location to sustainable digital infrastructure and Europe’s need for resilient modern capacity.
Residents raised objections during a June town hall meeting, including concerns about the height of proposed buildings and the transparency of the planning process. Local authorities have not yet granted permission.
Wind power does not settle planning
North Frisia sits at the sharp end of a European siting shift. Developers are looking beyond the largest metropolitan hubs towards regions with renewable energy, available land, and potentially easier routes to grid capacity. Those areas are often rural or semi-rural, and many have not previously hosted infrastructure with hyperscale electrical loads.
A 150MW data centre is a large industrial user. Even where regional electricity is abundant, the development still changes land use, skyline, construction traffic, noise conditions, emergency generation requirements, and local heat rejection. The load may look attractive to a renewable-heavy region, but the buildings still need a social licence as well as a grid connection.
The Langenhorn proposal sits within a wider Schleswig-Holstein discussion. Other data centre schemes have been floated in the state, and local stakeholders have called for clearer regional strategy rather than one-off municipal decisions on very large loads.
That question is becoming more urgent across Germany. Data centre development has historically clustered around Frankfurt, where network connectivity and enterprise demand are strongest. Constraints in established hubs are now pushing developers into new regions, but those regions need planning frameworks, grid studies, heat-use options, and public engagement processes able to handle projects measured in hundreds of megawatts.
Powered land still has to be bankable
UNIQ LAND describes its broader model as data centre land development across the DACH region, including site screening, permitting, grid connection, and ready-to-build land. Langenhorn puts that model into public view: a powered-land opportunity only becomes bankable when planning risk is controlled.
The project’s possible 300MW connection capacity also changes the local conversation. Even if the first phase were smaller, residents and local authorities will look at the end-state infrastructure. The difference between a 150MW phase and a 300MW campus affects grid planning, backup power, heat rejection, building massing, and cumulative regional impact.
Heat reuse could form part of the local case, particularly where large data centres are proposed close enough to homes, farms, or commercial users. Yet heat recovery is not automatic. It requires temperature compatibility, distribution infrastructure, paying heat customers, and a governance model that survives after consent is granted.
Opposition to data centres is also becoming more sophisticated. Communities are asking whether scarce clean power is being used well, whether promised jobs match the electrical load, and whether municipalities are being asked to approve strategically significant infrastructure without a state-level plan.
Langenhorn may still become a viable site. Schleswig-Holstein has renewable electricity, open land, and a growing role in Germany’s energy system. The local reaction so far is a warning to developers chasing power-rich regions: renewable siting strengthens the carbon case, but it does not settle the planning case.
Germany’s next data centre geography will be shaped by more than megawatts. Early engagement, a credible local benefit case, transparent design, and state-level coordination will decide whether powered land becomes buildable land.
