Colocation data center: per-kW prices across Europe in 2026
Frankfurt, London, Amsterdam, Paris, Madrid: what does 1 kW of premium colocation really cost in 2026? Full benchmark.
2026 context
AI demand has blown up colocation pricing: +38% in 2 years across European Tier-1 hubs (FLAP-D: Frankfurt, London, Amsterdam, Paris, Dublin).
2026 premium colocation rates (€/kW/month)
| City | Setup | Recurring /kW/month | Energy €/MWh | Verdict |
|---|---|---|---|---|
| Dublin | €850 | €245 | 110 | Saturated, frozen |
| Frankfurt | €720 | €195 | 95 | Premium, 18-month wait |
| Amsterdam | €680 | €185 | 88 | Centre moratorium |
| London | €760 | €215 | 105 | Expensive energy |
| Paris | €650 | €175 | 78 | Nuclear = stability |
| Marseille | €520 | €138 | 75 | Intercontinental cables |
| Madrid | €480 | €125 | 60 | Solar available |
| Milan | €510 | €132 | 82 | Growing hub |
| Stockholm | €420 | €108 | 38 | PUE 1.1 |
| Warsaw | €380 | €95 | 65 | Emerging |
The hidden cost: energy
Over a 7-year cycle, energy is 55–65% of colocation TCO. A Voltarione PPA at -€25/MWh saves over 7 years for 1 MW: €1.52M.
Recommendation by profile
- European latency-critical: Paris or Frankfurt + Voltarione France/Germany PPA
- AI training, non latency-bound: Stockholm or Madrid + solar/hydro PPA
- Multi-zone backup: Marseille + Madrid + Warsaw triangle inside ENTSO-E

How much electricity does an AI data center really consume? A 2026 European benchmark (MW, €/MWh, PPA)
A frontier AI training cluster now draws 100–300 MW continuously, inference already accounts for 80–90% of AI compute, and the all-in energy cost of a 100 MW campus ranges from €38–55M/year in the Nordics to €118–149M/year in Dublin. A data-heavy 2026 European benchmark.
