Two large lithium-ion batteries will be built and connected to the grid in regional Victoria this year, giving the state’s west a significant renewable energy boost in time for next summer.

The batteries, which will store solar and wind-generated energy, will be built near Ballarat and Kerang and will have a combined generation capacity of 55 MW and a combined energy storage of 80 megawatt-hours – giving them more than half the power of South Australia's gigantic 100MW Tesla battery.

The batteries will be built in the state’s west, which is identified as having a vulnerable energy transmission network.

The Turnbull government has committed up to $25 million to what will be the first installation of large-scale, grid-connected batteries in Victoria.
