Vehicle-to-Grid (V2G) technology allows you to use the large battery in your electric vehicle to power your home and even sell energy back to the grid. In 2026, what was once a future concept is now becoming a reality for Australian households, thanks to major trials from energy retailers, newly approved hardware, and growing support from car manufacturers. While not yet a mainstream off-the-shelf product, V2G is moving out of the lab and into driveways, offering a compelling alternative to a stationary home battery.
This guide breaks down the essential information for 2026: the required technology, the costs involved, which cars are compatible, and whether it makes financial sense for you.
How Does V2G Work in Australia?
Standard EV charging is a one-way street: electricity flows from the grid or your solar panels into your car. V2G, enabled by a special bidirectional charger, creates a two-way street.
- Vehicle-to-Home (V2H): You can use the energy stored in your EV to power your home. This is particularly valuable during evening peak hours when electricity prices are highest, allowing you to run on stored solar or cheap off-peak energy instead of drawing from the grid.
- Vehicle-to-Grid (V2G): You can export surplus energy from your EV back to the electricity grid. Energy retailers, through programs often called Virtual Power Plants (VPPs), can pay you for this energy, especially during periods of high demand or grid instability.
Essentially, your car doesn’t just sit idle — it becomes an active asset that can lower your energy bills and even generate income.
What Do You Need for a V2G Setup in 2026?
Getting V2G-ready involves three key components:
- A V2G-Compatible EV: Not all EVs can discharge power. The vehicle’s internal hardware and software must be designed for bidirectional flow. While the Nissan Leaf and Mitsubishi Outlander PHEV have long been the primary examples, 2026 sees this list expanding through official trials.
- A Bidirectional Charger: This is the critical piece of hardware that manages the two-way energy flow. These units are more complex and expensive than standard chargers. As of April 2026, several models are now approved for use in Australia by the Clean Energy Council.
- Network and Retailer Approval: You need permission from your local electricity network operator (known as a DNSP) to connect a device that can export power. You also need to be with an energy retailer running a V2G program to manage the process and provide financial rewards.
V2G-Ready EVs in Australia
Historically, V2G in Australia was limited to EVs using the CHAdeMO charging standard. However, the focus in 2026 has shifted to the more common CCS2 standard, with several brands now officially supporting V2G within controlled trials — a crucial step that protects your vehicle’s battery warranty.
| Vehicle Model | V2G Status in 2026 | Battery Size (Usable) | Charging Plug |
|---|---|---|---|
| Nissan Leaf | Commercially available | 39 kWh | CHAdeMO |
| Mitsubishi Outlander PHEV | Commercially available | 13.8 kWh | CHAdeMO |
| Kia EV9 | Hardware confirmed V2G-ready | 99.8 kWh | CCS2 |
| Select BYD models (e.g., Atto 3) | Supported in AGL, Origin & Amber trials | 60.5 kWh | CCS2 |
| Select Hyundai models | Supported in AGL trial | Varies by model | CCS2 |
| Select Kia models (e.g., EV6) | Supported in AGL trial | 77.4 kWh | CCS2 |
A key barrier to V2G adoption has been vehicle battery warranties. The launch of major trials in 2026 with direct manufacturer support from brands like BYD, Kia, and Hyundai is a game-changer, giving consumers confidence that using their car as a battery won’t void their warranty.

The Costs: V2G Charger vs. a Home Battery
The primary financial decision for many households is whether to invest in a V2G setup or a traditional stationary home battery like a Tesla Powerwall. A V2G setup has a lower hardware cost but relies on your car being plugged in, whereas a home battery is a dedicated, always-on device.
| Item | V2G Setup | Dedicated Home Battery | Notes |
|---|---|---|---|
| Main Hardware | Bidirectional Charger | Tesla Powerwall 3 | The Powerwall 3 has now replaced the Powerwall 2 in Australia. |
| Hardware Cost (AUD) | $6,000 - $10,000+ | $12,000 - $15,000 | V2G charger prices vary by model (e.g., StarCharge Halo RRP $6,000, Numbat from $10,000). Powerwall pricing is for the unit only. |
| Installation Cost (AUD) | $1,500 - $3,000+ | $2,000 - $4,000+ | Both require a qualified installer and may need switchboard upgrades. |
| Total Estimated Cost | $7,500 - $13,000+ | $14,000 - $19,000+ | For financing options, see our guide on Best Solar Panel & Home Battery Financing Options in Australia 2026. |
| Storage Capacity | 50 - 100 kWh | 13.5 kWh | V2G unlocks the full capacity of your car’s battery (e.g., ~60 kWh for a BYD Atto 3). |
The Financial Payback: Is V2G Worth It?
With a significantly larger battery capacity for a lower upfront cost, V2G presents a strong financial argument. The savings come from two main areas:
- Bill Reduction (V2H): By using your EV to power your home from 4 pm to 9 pm, you can drastically reduce your reliance on expensive peak-rate grid electricity. This strategy, known as ‘load shifting’, is the most immediate benefit.
- Grid Earnings (V2G): Participating in a VPP allows an energy retailer to draw power from your car during critical grid events. Early results from Australian trials show this can be highly lucrative. One household earned $300 overnight, while another made $257 in a single day. The Electric Vehicle Council estimates a typical V2G user could earn around $1,000 per year.
Major energy retailers are now leading the charge. AGL is running a 100-person trial across VIC, NSW, QLD, and SA with discounted chargers. Origin Energy is offering a subscription bundle including a BYD Atto 3, a StarCharge bidirectional charger, and a specialised energy tariff with free home charging for up to 24,000km per year.
Bottom Line
In 2026, Vehicle-to-Grid technology in Australia is making its decisive move from theory to practice. It is no longer a question of if, but how it will be rolled out. For the average consumer, it is not yet a simple case of buying a charger at a retailer and plugging it in. Availability is largely confined to those participating in the landmark trials run by AGL, Origin, and others.
However, the value proposition is becoming undeniable. A V2G setup costs significantly less than a standalone home battery of a comparable size and unlocks an enormous energy storage resource you already own. If you are an EV owner (or prospective buyer) in NSW, VIC, QLD, or SA with a compatible vehicle, applying to join one of the current V2G trials is the single best way to access this technology in 2026. For everyone else, the progress this year means a wider commercial release is now firmly on the horizon.
