Australian electric vehicle (EV) owners could have access to cheaper electricity and gas following a new program designed to introduce vehicle-to-grid (V2G) charging across the country.

Energy company AGL has launched a new national trial of bi-directional V2G technology in partnership with several automakers as it finalises plans to leverage government approval ahead of a potential rollout to customers in 2026.

Auto brands Hyundai, Zeekr, Kia and BYD are working with AGL during the trial, ensuring owners of vehicles from those brands used in testing will not have their warranties voided as a result. 

Fifty electrified vehicles – including EVs and plug-in hybrids (PHEVs) – will be used as part of the testing over a 12-month period, with participants given a discounted bi-directional charger that will give them the opportunity to reduce their power bills.

A further 50 places are available for additional participants who already have or are willing to purchase AGL-approved charging equipment.

V2G technology refers to the ability of electrified vehicles to feed power back into the electricity grid. In this case participating owners will receive a credit from AGL towards their future energy bills, including both power and gas. 

V2G goes a step beyond vehicle-to-home (V2H) charging tech, which also provides a safety net in the event of electricity blackouts by allowing vehicles to power homes or otherwise. 

“Unlocking the potential of car batteries is a game changer for owners, by allowing them to reduce their energy usage costs, and for the broader community by contributing to grid stability during periods of peak energy demand,” AGL head of innovation and strategy, Renae Gasmier, said in a statement.
