In a bid to foster electric grid stability and renewable energy penetration, the Australian state of Victoria has contracted with Neoen SA, France, to deliver a 300 MW/450 MWh storage lithium-ion Tesla battery.

The Victorian Big Battery increases the power flow through the Victoria-New South Wales Interconnector (VNI), allowing Victoria to draw an additional 250 MW from the adjoining state in periods of peak demand between The Victorian Big Battery will charge during the day when renewable energy is cheap and abundant and then dispatch energy as needed. Source: NeoenNovember and March each year and increase supply reliability. The battery will be able to charge during the day when renewable energy is cheap and abundant and then dispatch that energy as needed, lowering power costs for consumers.

Neoen previously claimed title as owner of the world's largest battery with its Hornsdale 315 MWt facility fed by 99 wind turbines in South Australia. The new Victoria facility will be three times the size of the Hornsdale plant.

The battery system is expected to have the capacity to power half a million homes for one hour and is ideally situated in a region flush with wind farms and solar installations. When the project is completed at the end of 2021, the power grid will rely on continuous computer analysis to determine which regions need supplemental power, how much is required and when to deliver it.
