The Australian Renewable Energy Agency (ARENA) has committed an additional AUD$13.5 million to expand Amber Electric’s vehicle-to-grid (V2G) and smart charging programs, effectively enabling more electric vehicle (EV) owners to use their cars as ‘driveable home batteries’. Announced on June 1, 2026, this significant funding injection aims to enrol an additional 950 customers into the V2G program and over 1,000 into smart charging initiatives, marking a critical step in integrating EVs into Australia’s energy grid.
This latest investment brings ARENA’s total support for Amber Electric’s V2G and smart charging efforts to AUD$16.8 million, building on an initial AUD$3.2 million contribution made in 2024. The move underscores a federal push to leverage the growing fleet of EVs for grid stability and household energy management, offering a new pathway for Australians to cut electricity costs and contribute to the renewable energy transition.
What is Vehicle-to-Grid (V2G) Technology?
V2G technology is a two-way system that allows an EV battery to not only charge from the electricity grid but also to export stored energy back to it when needed. This capability transforms an EV from a mere transport device into a flexible energy asset, functioning much like a conventional home battery storage system.
For Australian households, the benefits are threefold:
- Cost Savings: EV owners can earn income by exporting surplus energy back to the grid, particularly during peak demand periods when electricity prices are higher. This can significantly offset charging costs and overall energy bills.
- Solar Optimisation: Homes with rooftop solar can charge their EVs during the day using excess solar generation and then discharge that stored energy for household use in the evening, reducing reliance on grid electricity when the sun isn’t shining.
- Grid Stability: On a larger scale, aggregated V2G-enabled EVs can help stabilise the national electricity grid by providing dispatchable power, reducing pressure during peak demand, and supporting the integration of more renewable energy sources.
“V2G is a two-way technology that allows people to use their EV battery to store energy and send electricity back to the electrical grid when needed.”
While V2G technology offers substantial advantages, concerns about potential battery wear from more frequent charging and discharging cycles have been raised. However, proponents argue that smart energy management systems and advancements in battery technology are helping to minimise these effects.
Expanding Access and Addressing Barriers
ARENA’s expanded program is specifically designed to tackle existing barriers hindering widespread V2G deployment across Australia. These include crucial areas such as charging standards, interoperability between different EV models and charging infrastructure, and addressing battery warranty concerns.
ARENA CEO Darren Miller emphasised the necessity of collaboration to scale this technology effectively, stating, “To unlock V2G at scale, we need to bring together customers, car makers, networks and technology providers.” This collaborative approach is vital to ensure a seamless and reliable V2G ecosystem that benefits both consumers and the broader energy market.
The Role of Smart Charging
Alongside V2G, the smart charging component of Amber Electric’s program plays a crucial role. Smart charging allows EV owners to automatically charge their vehicles when electricity prices are low and emissions are minimal, typically during periods of high renewable energy generation. This intelligent charging helps maximise cost savings for EV owners and further supports the efficient use of clean energy.

Impact on Australia’s Energy Future
The federal government’s “Driving the Nation Program” prioritises V2G support as part of its broader strategy to accelerate Australia’s shift to electric vehicles and enhance EV charging infrastructure. By enabling EVs to act as flexible energy resources, Australia can better manage its grid during periods of high demand or low renewable output, reducing reliance on traditional fossil fuel generators.
This expansion of V2G capability complements the rapid growth of stationary battery storage across the country. Australia has seen substantial increases in both home and utility-scale battery installations, positioning it as a global leader in battery storage capacity. This growing battery fleet is already contributing to lower wholesale electricity price spreads by absorbing midday solar surpluses.
As more Australians adopt EVs and home battery solutions, programs like Amber Electric’s, backed by ARENA, are crucial for unlocking the full potential of these technologies. They empower individual households to become active participants in the energy market, contributing to a more resilient, sustainable, and cost-effective energy future for the nation.
How Your EV Compares to a Home Battery
While a dedicated home battery system like a Tesla Powerwall or Sungrow SBR offers seamless integration with rooftop solar for household consumption, V2G-enabled EVs provide a unique advantage: mobility. The average EV battery capacity often significantly exceeds that of a typical home battery, offering a larger potential storage resource for both personal use and grid support.
| Feature | Dedicated Home Battery (e.g., Tesla Powerwall 2) | V2G-Enabled Electric Vehicle (e.g., Nissan Leaf) |
|---|---|---|
| Primary Function | Stationary energy storage for home | Transport, with optional energy storage/export |
| Capacity (Usable) | Typically 10-14 kWh | Often 40-90 kWh+ |
| Mobility | None | Yes |
| Grid Interaction | Store solar, time-shift, VPP participation | Store solar/grid, time-shift, VPP (via V2G) |
| AUD Price (Installed) | AUD$13,000 - $18,000 (excl. rebates) | Varies by EV model (AUD$40,000 - $100,000+) |
This expanded program is a clear indication that the line between transportation and home energy management is blurring, creating new opportunities for Australians to save money and support the grid. Understanding how to best size a home battery for your solar system and usage is also key, as detailed in Your 2026 Guide: Precisely Sizing a Home Battery for Your Solar System & Usage.
The federal government continues to support cleaner, cheaper energy solutions, and the latest V2G funding is set to accelerate the adoption of these innovative technologies, offering tangible benefits for Australian households.
