Data centres and airports: energy resilience synergies and stranded asset risks
Reviewed by Joe Ashwell
First reported on New Civil Engineer
30 Second Briefing
Potential “symbiotic” energy resilience relationships between data centres and airports are being explored, as both require N+1 or higher redundancy, dual grid feeds and on-site backup generation to keep 24/7 operations running. An airports strategy expert suggests co-locating hyperscale data halls with major hubs could justify shared high-voltage substations, large-scale battery storage and potentially hydrogen-ready CHP plant sized for peak aviation and IT loads. However, the expert warns that current demand projections for data centres may be a bubble, risking stranded electrical and civil infrastructure if growth stalls.
Technical Brief
- Shared HV yards imply integrated earthing, fault-level coordination and protection selectivity across aviation and IT feeders.
- Civil works could consolidate cable tunnels, duct banks and transformer compounds within common secure airside/landside corridors.
- Hydrogen-ready CHP plant would require dedicated bunded fuel farms, blast stand-offs and hazardous area zoning.
- Large battery systems near runways trigger additional fire engineering, smoke control and ICAO obstacle limitation assessments.
- Noise and vibration from standby generation must be attenuated to protect both terminal structures and server racks.
- Grid-connection consents and wayleaves could be pooled, but stranded-asset risk complicates long-life substation and trench design.
- For similar multi-user energy hubs, contract structures need clear allocation of capex, redundancy obligations and decommissioning liabilities.
Our Take
New Civil Engineer’s recent collaboration with Heathrow Airport on its Early Careers Innovation Challenge suggests UK airports are actively scouting unconventional infrastructure ideas, so a ‘symbiotic’ model with data centres could find a ready testbed at hubs like Heathrow.
Within our 857 Infrastructure stories, relatively few pieces link digital infrastructure directly with airport energy systems, so this concept sits at the edge of current practice rather than reflecting an already-established model.
Given New Civil Engineer’s coverage of BIM, common data environments and digital handover, any airport–data centre energy pairing will likely hinge on robust shared data architectures, not just physical co-location of plant and backup power.
