Colocation data center: per-kW prices across Europe in 2026

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
