A 240MWp / 480MWh battery in the Mornington Peninsula will join Victoria’s growing cohort of utility-scale batteries after securing development approval this week.

The $190 million project by renewables developer Maoneng is expected to be done in 18 months and will employ 160 during its construction.  

It will be located next to AusNet’s existing Tyabb substation and will be used to help the grid to respond to fluctuations in demand caused by the influx of tourists visiting the area at certain times of the year. The battery will draw and store energy from the grid during off-peak periods and dispatch energy to the grid during peak periods.

The state has recently turned on Neoen’s 300 MW / 450 MWh big battery in Geelong that became operational late last year and took less than a year to construct.

Last year was a big year for grid-scale battery announcements in Australia. According to the Clean Energy Council, as of October 2021 there were 23 battery projects under construction or due to start soon around Australia.

These battery storage projects are expected to deliver 1425 MW of new energy storage capacity with the ability to discharge 2838 MWh.
