EV charging company Zaptec has set out its vision to transform airport parking into strategic energy hubs using vehicle-to-grid (V2G) technology to stabilise the grid.

Zaptec charging infrastructure at Oslo Airport shows how sites can be turned into a flexible energy resource

As UK airports and transport hubs increasingly roll out EV charging infrastructure, the company believes there is a growing opportunity to go beyond simple driver convenience and use airport car parks to support future-ready energy systems, helping operators cut energy costs, boost resilience and support a more stable grid.

Zaptec already supports major EV charging deployments across the Nordics. At Oslo Airport Gardermoen, the company provides charging across hundreds of parking bays, with advanced load and phase balancing and MID‑compliant metering. The Zaptec system charging architecture is designed so that V2G functionality can be integrated as V2G‑capable vehicles and market frameworks mature, which can turn sites into a flexible energy resource over time.

With hundreds of connected EVs and their in‑built batteries onsite, idle airport car parks can transform into dynamic energy assets, according to Michael Braybrook, UK managing director at Zaptec.

By acting as a distributed energy reserve, V2G‑enabled EV charging infrastructure offers airports and other transport hubs the ability to use stored energy in parked vehicles to support their own systems at critical times, or export energy back to the grid when it is most valuable. This can help reduce peak demand charges, provide flexibility services and improve overall operational resilience.

V2G capability could also be critical in maintaining essential energy services such as lighting, communications and safety systems in the event of a power disruption, similar to the outage experienced at Heathrow Airport in March 2025.

Designing airport EV charging infrastructure with smart load management and future V2G integration in mind from day one will allow operators to treat car parks as flexible energy assets, accelerating low‑carbon infrastructure, supporting sustainability targets and ultimately advancing their net zero goals.

“At the same time, travellers still get what they expect, cars automatically charged and waiting for them when they get back from their trip,” Braybrook added.
