FLAP-D grid connection thresholds for data centers

In Europe’s core markets, rationing starts at small sizes: 3.5 MW in Frankfurt (above 1 MW in local bottlenecks), 3.5 MVA in Berlin, 5 MVA with a 2,000 m² floor cap in Amsterdam, about 40 MW before a Paris-area project moves from Enedis to RTE, 1 MVA in Dublin, and multi-year waits above 1 MVA in West London.

Quick answer

In Europe’s core markets, rationing starts at small sizes: 3.5 MW in Frankfurt (above 1 MW in local bottlenecks), 3.5 MVA in Berlin, 5 MVA with a 2,000 m² floor cap in Amsterdam, about 40 MW before a Paris-area project moves from Enedis to RTE, 1 MVA in Dublin, and multi-year waits above 1 MVA in West London.

Key facts

Ireland: data centres at or above 1 MVA must show a credible plan to meet at least 80% of annual demand from new Irish renewable generation, within a six-year glide path (Mason Hayes & Curran).
Berlin’s first allocation: about 2,300 MVA requested against 365 MVA available (ingenieur.de).

Where connection rules change, by city
City	Threshold	What happens above it	Source
Frankfurt	3.5 MW (1 MW in bottlenecks)	Pro-rata allocation of new requests by NRM	ingenieur.de
Berlin	3.5 MVA	Annual allocation; 37 of 70 requests got capacity in the first round	ingenieur.de, Raue
Amsterdam	5 MVA and 2,000 m²	Zoning restricts new or expanded data centers	Gemeenteblad 2026-433374
Paris region	≈40 MW	Connection moves from Enedis distribution to RTE transmission	Grid Readiness
Dublin	1 MVA	CRU rules: 1–10 MVA needs an autoproducer covering 100% of MIC	Mason Hayes & Curran
West London	1 MVA	Multi-year waits, some connection dates toward 2035	Data Centre Axis
