Ausgrid has successfully connected a vehicle-to-grid (V2G) system to its electricity network—a significant step that will allow electric vehicles (EVs) to both draw power from the grid and discharge energy back into it.
The two-way flow of energy transforms EVs into mobile batteries, capable of supporting the network during peak times and providing a new level of energy independence for customers.

Ausgrid group executive distributed services Rob Amphlett Lewis said tapping into V2G was an exciting milestone that unlocked new opportunities for customers and the grid.
“We’ve done the foundational work to understand how to integrate this V2G technology safely and effectively and our customers can now begin to benefit,” he said.
“Customers can use their EV batteries to sell excess energy back to the grid during peak times and recharge at off-peak rates, creating an additional source of income.
“V2G transforms EVs into more than just a transportation tool—for customers that are interested, they can become income-generating assets and energy-management systems, enhancing the overall value and practicality of owning an EV.”
With a typical car battery approximately six times the size of an average home battery, the integration of V2G technology can offer advantages similar to those offered by home batteries, but on a larger scale.

Ausgrid head of customer connections Fatima Bazzi said, “This is a game-changer and we are excited to see how this technology will enable our customers to take a more active role in the energy ecosystem, turning their electric vehicles into a valuable resource that can support their homes and earn them income.
“V2G allows EVs to discharge energy back to the grid during periods of high demand, alleviating stress on the network and improving overall grid performance.”
