When the power grid runs low, your EV's battery could help

London

THE Nissan Leaf sitting in Paul Kershaw's driveway outside Cambridge, England, might look like just another car, waiting for its driver to take it for a spin. But the electric vehicle (EV) has been more than a means of transportation. It's also powered appliances, streetlights and other grid-reliant machinery in the neighbourhood.

The exchange of power is part of a trial launched in 2019 by Ovo Energy Ltd, the UK's second biggest energy supplier. When Mr Kershaw heard about the programme, he applied to be one of 330 people to register his car as an energy-storage device. "I use my car only one per cent of the time so knowing that my car is there, and it's active and it's doing something, it's being used to balance the grid," Mr Kershaw said, "it's great knowing that."
