The Victorian Big Battery (VBB) modernises the state’s electricity grid and boosts the reliability of power supply in the face of increasingly hot summers.

The 300 Megawatt (MW) battery is owned and operated by renewable energy specialist Neoen, and can store enough energy to power more than one million Victorian homes for 30 minutes.

It is one of the largest batteries in the world, promising to strengthen Victoria’s energy reliability, drive down electricity prices, and support the transition to renewable energy and net-zero emissions.

Modernising Victoria's electricity system

With climate change resulting in hotter summers, peak demand for electricity is rising. At the same time, Victoria’s ageing coal-fired generators are becoming increasingly unreliable, resulting in a need for additional capacity to ensure the state’s power supply.

The ‘Victorian Big Battery’ operates as a virtual transmission line between November and March each year, enabling increased flows of up to 250MW over the Victoria-New South Wales interconnector. This reduces the risk of unscheduled load shedding over the peak summer months.

The battery also participates in energy markets throughout the year, with 50MW available for this purpose during the summer and the full 300MW at other times. This additional capacity will lower electricity prices for all Victorians and deliver significant net benefits to Victoria, far outweighing the cost of the project.
