In February, the Australian energy grid experienced a significant blackout due to major storms in Melbourne. In a groundbreaking event, ACT Government vehicles played a crucial role in stabilizing energy grid by feeding power back into it. This marks a potential first in the world where vehicle to grid V2G technology has been deployed to assist during a power emergency.
The Incident and Response
The blackout, caused by severe storms, affected a large portion of the grid. At the time, 16 ACT Government fleet electric vehicles (EVs) were connected to V2G smart chargers across the ACT. Out of these, four were actively charging while 12 were idle. Upon receiving a signal from the grid, these EVs began supplying power back into the grid within seconds. This emergency response lasted only a few minutes before the grid stabilized, allowing the vehicles to resume charging with minimal disruption.

How V2G Technology Works
V2G technology operates through a bi-directional charger that allows energy from an EV battery to flow back into the grid, similar to how rooftop solar panels work. This capability transforms EVs from mere consumers of electricity into dynamic assets that can support the grid during peak demand or emergencies.
Benefits of V2G
The successful deployment of V2G technology during the blackout highlights its significant potential benefits:
- Enhanced Grid Security: V2G can provide critical support to the electricity grid during emergencies, ensuring stability and preventing prolonged outages.
- Reduced Emissions: By using EVs to supply power, reliance on fossil fuels is reduced, leading to lower greenhouse gas emissions from the transportation sector.
Ross De Rango, Head of Energy and Infrastructure at the Electric Vehicle Council, emphasized the importance of V2G technology for Australia’s future. “V2G represents a huge opportunity for Australia,” he said. “Over time, it will put downward pressure on energy bills for everyone (not just EV drivers) and enable us to close coal and gas-fired power stations sooner.”
Broader Implications
The growing uptake of EVs in Canberra and the potential for V2G technology to be integrated nationwide could play a pivotal role in Australia’s transition to renewable energy. By harnessing the power stored in EV batteries, significant portions of peak energy demand can be met without burning fossil fuels, recharging the vehicles later from excess wind or solar power.

The deployment of V2G technology is part of the ACT’s first Integrated Energy Plan, reflecting a commitment to innovative solutions for a sustainable future. For more information on the ACT’s pathway to electrification and its Everyday Climate Choices, visit the Everyday Climate Choices website.
In conclusion, the successful use of V2G technology during the February blackout is a testament to the potential of EVs in enhancing grid stability and promoting renewable energy. As Australia continues to embrace sustainable practices, V2G stands out as a promising innovation that benefits both the environment and the economy.
