Person plugging in charger to their EV

Excess EV energy could recharge grid

In the near future electric cars could help the UK’s electricity networks meet demand by sending excess energy back to the grid at peak times, according to one distribution company.

Western Power Distribution (WPD) is currently undertaking a trial to see how a Vehicle to Grid (V2G) system could work. EV owners would be able to plug their cars into a charger, which would then draw power from the car at peak times, then charge the car during off-peak periods.

During peak times of the day when more electricity is used in people’s homes, more electricity has to be generated, which requires the burning of fossil fuels from power stations, damaging the environment. A nationwide network of batteries, however, can store electricity generated from renewable sources at non-peak times, feeding it back to the grid at peak times.

Electric vehicle batteries have the potential to deliver the necessary nationwide storage, which is what WPD’s trial is testing.

Called the Electric Nation project WPD is recruiting 100 Nissan EV owners in the Midlands, South West England and South Wales to take part in the trial of V2G smart charging technology.

The company is working with a wide range of organisations, including local authorities, housebuilders and fuel station operators to facilitate the installation of more charge points, including at EV filling stations/charging hubs, and through on-street charging solutions for the 40 per cent of homes that don’t have off-street parking.
