Mostly by staying under the size where scarce-capacity rules start, buying sites that already hold capacity, moving just outside the constrained grid, or bringing their own power. Thresholds are low: 3.5 MW in Frankfurt (1 MW in local bottlenecks), 3.5 MVA in Berlin, 5 MVA and 2,000 m² in Amsterdam, 1 MVA in Dublin.

Key facts
- Frankfurt (NRM): new requests of 3.5 MW or more are allocated pro rata; in local bottlenecks from above 1 MW (ingenieur.de).
- Berlin: from 3.5 MVA, capacity is shared out once a year; 70 requests for about 2,300 MVA met 365 MVA available, 47 qualified and 37 received capacity (ingenieur.de).
- Amsterdam: zoning restricts data centers above 2,000 m² floor area and 5 MVA connection capacity (Gemeenteblad 2026-433374).
- Dublin: below 1 MVA a site is exempt from the CRU data centre decision; 1–10 MVA sites must provide an autoproducer unit covering 100% of MIC (Mason Hayes & Curran).
- Germany’s Data Center Capital launched with eight sites of 2–9.5 MW, 46 MW in total, all in southern German cities (IDCNova).
The six routes
- Stay under the threshold (edge and enterprise sites of 1–3.5 MW).
- Buy a site that already holds capacity, such as an existing building or older data center.
- Use approvals granted before the rules tightened.
- Move just outside the constrained grid area.
- Own or nearby generation (required in Dublin for 1–10 MVA).
- Accept a non-firm connection where offered.
Questions
Is there a ban on data centers in these cities?
Why are secondary German cities attractive?
