Australian electric vehicle (EV) owners are set to gain greater control over their energy bills, with the Australian Renewable Energy Agency (ARENA) injecting an additional AUD$13.6 million into Amber Electric’s pioneering vehicle-to-grid (V2G) pilot project. Announced on May 29, 2026, the funding expansion brings ARENA’s total commitment to the trial to AUD$16.8 million, significantly scaling up efforts to integrate EVs directly into the national energy system.
The expanded program will see the number of households participating in V2G technology increase from 50 to 1,000, while smart EV charging capabilities will extend to 2,000 households, up from 950. This initiative aims to gather crucial real-world data on how EVs can not only reduce individual household energy costs but also provide vital support to Australia’s electricity grid by optimising charging times and feeding power back when needed most.
Unlocking Your EV’s Hidden Potential
For many Australian households, rooftop solar systems generate abundant electricity during daylight hours. However, much of this energy is often exported to the grid for a low feed-in tariff, while homes then draw expensive power back during evening peaks. V2G technology fundamentally alters this dynamic by transforming an EV into a mobile home battery, allowing owners to store their excess solar generation and discharge it to power their homes when grid electricity prices are high.
Federal Minister for Climate Change and Energy, Chris Bowen, emphasised the dual benefits of the program, stating, “Vehicle-to-grid technology means your car does not just get you from A to B, it can help power your home and support the grid.” This capability enables households with solar to maximise self-consumption, significantly reducing their reliance on grid power and potentially cutting annual electricity bills by hundreds, or even thousands, of dollars. Early estimates suggest that optimising EV charging with solar could slash bills by over AUD$1,500 annually.
“To unlock V2G at scale, we need to bring together customers, car makers, networks and technology providers. A big part of that is giving manufacturers the confidence their vehicles will perform as expected, including through validated approaches to battery use and warranties.” – Darren Miller, ARENA CEO
Amber Electric’s smart charging technology plays a pivotal role, automatically charging EVs when wholesale electricity prices are low and when rooftop solar generation is abundant. Conversely, drivers can program their EV to discharge power to their home or even sell it back to the grid during peak demand periods, all while maintaining a user-defined minimum state of charge.
The Technical Shift: How V2G Works
V2G technology relies on bi-directional chargers that allow electricity to flow both into and out of an EV’s battery. This contrasts with conventional AC home chargers, which typically only allow power to flow in one direction. While the number of V2G-capable EVs and compatible chargers is currently limited, trials like Amber’s are crucial for developing the necessary infrastructure and proving the economic and grid-stability benefits. The expansion aims to understand customer behaviour, technology performance, and market integration, with results informing future policy and industry investment.
Table: V2G Trial Expansion Details
| Feature | Before May 29, 2026 | After May 29, 2026 Expansion |
|---|---|---|
| ARENA Funding | AUD$3.2 million | AUD$16.8 million (total) |
| V2G Households | 50 | 1,000 |
| Smart Charging Households | 950 | 2,000 |
This move aligns with broader efforts to modernise Australia’s grid, which is increasingly dealing with high levels of intermittent renewable energy. By leveraging distributed energy resources like V2G-enabled EVs, the grid can become more resilient and efficient. For homeowners, understanding how to optimise EV charging with solar in 2026: slash bills by $1,500+ annually is becoming increasingly important.
The Road Ahead for Australian EV Owners
ARENA CEO Darren Miller has set an ambitious target of one million V2G-capable EVs on Australian roads by 2035. Achieving this will require close collaboration between consumers, car manufacturers, network operators, and technology providers to ensure vehicles perform as expected and warranties are robust.
The expansion of Amber Electric’s V2G trial, launched in Lidcombe, Western Sydney, represents a significant step towards this goal. It provides a real-world testbed for the technology, moving beyond theoretical models to practical application in Australian homes. As more EV models enter the market with V2G capabilities, and as smart charging infrastructure becomes more widespread, the financial benefits for solar-equipped EV owners are expected to grow substantially. This development also highlights the evolving landscape for managing household energy, where understanding how to size a home battery for your solar system will soon extend to integrating your electric vehicle.
This initiative not only promises significant individual savings but also contributes to national energy security and the broader transition to a low-carbon economy. As electricity prices continue to be a concern for many, the ability to turn a depreciating asset like a car into a valuable energy storage device offers a compelling new pathway to energy independence.

The outcomes of this expanded trial will be closely watched by industry and consumers alike, as they will inform the future shape of Australia’s energy market and the role of EVs within it.
