TransPower Vehicle to Grid (V2G)

TransPower will investigate network impact and flexibility services for vehicle-to-grid (V2G) from domestic, commercial and public charging through demonstrator trials and collaborative research and development.

We are leading projects on:

  • Bus2Grid: Supporting a project to turn a 30-bus garage into the first of its kind in the UK V2G bus garage.
  • E4Future: A ¬†trial on 1,000 V2G fleet vehicles
  • PowerLoop: Domestic customer V2G trial involving customers in specific areas.
  • V2Street: Public charging networks with a local authority and a charge point provider. Targeted at the 60-70% of Londoners without off-street charging capability.

Project data

Start date: 02/04/2018
End date: 01/09/2021
Budget: £1.345m

The integration of renewable energy sources, and the forecasted growth of EVs present a number of challenges and opportunities for distribution networks. Until now there has been limited demonstration of V2G in the UK, in particular Distribution System Operator services and revenue stacking have yet to be explored, both of which are key to unlocking the commercial business case and customer offer of EVs.

This project explores V2G technology as one smart solution capable of reducing reinforcement costs due to electric vehicle (EV) uptake. UK Power Networks is evaluating the technical, commercial and customer proposition of V2G technology to the distribution network.

This project is the first in the UK to demonstrate Vehicle-to-Grid across a suite of V2G assets, from cars exporting at home to buses exporting at depots and cars powering lamp posts. UK Power Networks is seeking to unlock the value of vehicles being used as mobile batteries by developing new services through its DSO market that can generate revenue for customers.

Transpower sets out to establish the value of V2G flexibility and further prepare the business so that customers can benefit from it. A greater understanding and use of mobile battery assets (vehicles) has the potential to defer network reinforcement and support network resilience, facilitating the connection of additional loads and low carbon technologies.
