Big grid-scale batteries will be installed in South Australia’s mid-north in the same region as the Tesla and Neona batteries at Jamestown.

Battery and solar systems will be connected by Tilt Renewable to their existing wind farms, who will also place a pumped-hydro storage project in a disused quarry at Highbury in Adelaide’s north-east.

Besides only being about one fifth as powerful as the existing big batteries in the region, experts say the new additions of renewable energy storage will still help drive down energy prices.
