The vehicle-to-grid system allows cars to charge up when power is abundant and send electricity back into the grid when demand surges.

Octopus Energy Ltd., Britain’s largest power utility, has partnered with Chinese electric vehicle (EV) giant BYD Co. Ltd. on a service in the U.K. that can help EV owners cut down on charging costs by providing them with a way to supply electricity to the grid.

The Power Pack Bundle, launched last month, offers customers a leased BYD Dolphin and a special two-way charger that turns the car into a battery that can send electricity back to the grid during peak hours.
