The Australian Renewable Energy Agency (ARENA) has significantly escalated its commitment to vehicle-to-grid (V2G) technology, injecting an additional AUD$13.6 million into Amber Electric’s pioneering V2G project. Announced on May 29, 2026, by Federal Energy Minister Chris Bowen in Lidcombe, Western Sydney, this funding boost will scale up the number of households participating in bi-directional V2G charging from an initial 50 to a substantial 1,000 across Australia. The project’s smart charging trial will also double from 950 to 2,000 households.
This expansion, bringing the total government funding for Amber’s V2G initiative to AUD$16.8 million, signals a critical step towards integrating electric vehicles (EVs) more deeply into Australia’s energy system. The move is designed to build real-world evidence to support a national V2G rollout, potentially offering significant savings for EV owners and enhancing grid stability for all consumers.
Unlocking Your EV’s Hidden Power Potential
V2G technology allows compatible electric vehicles to not only draw power from the grid to charge their batteries but also to send electricity back to the grid. This bi-directional flow enables EVs to act as mobile battery storage units, discharging power to support homes during peak demand periods or even feed surplus energy back into the wider network. For participating households, this translates into potential savings on electricity bills by optimising when they charge and discharge, and by earning revenue for supporting the grid.
Amber Electric’s initial ARENA-funded trial, which received AUD$3.2 million, saw overwhelming interest with over 6,000 expressions of interest for just 50 V2G spots, demonstrating a strong consumer appetite for the technology. This demand underscored the need for a larger-scale trial to gather comprehensive data on customer behaviour, technology performance, and market integration.
“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. This project brings those pieces together to demonstrate how EVs can become an an active part of the energy system. That means savings for owners and better utilisation of the grid, which can bring down the cost of the network for everyone.” — Darren Miller, ARENA CEO
ARENA CEO Darren Miller has set an ambitious target of one million V2G-capable EVs on Australian roads by 2035, highlighting the technology’s potential to transform the energy landscape. The expanded trial aims to provide crucial insights to inform future policy and industry investment decisions, bringing together customers, car manufacturers, network operators, and technology providers.
How V2G Benefits Australian Households and the Grid
For Australian EV owners, V2G offers a compelling proposition beyond just transportation. By participating in programs like Amber Electric’s, they can monetise their vehicle’s battery, effectively turning a depreciating asset into a revenue-generating one. Imagine your EV offsetting your household’s evening peak demand, or even earning credits by exporting power back to the grid when prices are high. This can significantly reduce overall running costs, making EV ownership even more financially attractive. For those interested in optimising their EV charging, especially with rooftop solar, exploring options like smart chargers is crucial.

From a grid perspective, V2G offers unprecedented flexibility. A fleet of V2G-enabled EVs can act as a massive distributed battery, absorbing excess renewable energy during periods of high generation (e.g., midday solar) and discharging it when needed most. This helps stabilise the grid, reduce the need for expensive peaker plants, and ultimately contributes to lower electricity costs for all consumers. This aligns with broader efforts to integrate renewable energy and manage demand, similar to the benefits offered by home energy management systems.

Challenges and the Path Forward
Despite the significant potential, V2G adoption faces several hurdles, including vehicle compatibility, grid integration standards, and consumer awareness. Currently, only a limited number of EV models support bi-directional charging, though this is rapidly changing as manufacturers recognise the value proposition. The expanded Amber trial includes owners of eligible Hyundai, Kia, BYD, and Zeekr models, with manufacturers confirming that participation will not affect vehicle battery warranties.
Another key challenge is ensuring seamless coordination between regulators, energy retailers, car manufacturers, network operators, and equipment suppliers. The Vehicle-Grid Network (VGN), which received AUD$2.37 million in funding (including AUD$1.09 million from ARENA), is specifically designed to address this coordination problem, aiming to align stakeholders around common standards and market frameworks by November 2029.
As Australia continues its transition to a cleaner energy future, initiatives like the expanded Amber V2G trial are vital. They not only empower individual households to take control of their energy use and potentially reduce their energy bills but also lay the groundwork for a more resilient, efficient, and renewable-powered national energy grid. For those considering an EV, understanding charging options, including both AC and DC, is important.

The insights gained from this large-scale trial will be instrumental in shaping the future of EV integration and energy management across the country.
This federal government-backed initiative, occurring just days before the end of May 2026, marks a tangible commitment to leveraging EV technology for broader energy system benefits, moving beyond simple transportation to a future where electric cars are active participants in powering our homes and communities.
