EnergyAustralia is to develop a grid-scale battery alongside its Hallett Power Station in Canowie, 210 kilometres north of Adelaide.
The Hallett Battery Energy Storage System will have an initial storage capacity of 50MW and discharge capacity of up to 200MWh and be able to power up to 81,000 homes and small businesses for four hours.
EnergyAustralia said the project will undergo “further assessments and community consultation and is subject to the necessary South Australian planning approvals”. Subject to such approvals, the Hallett battery is expected to be operational at the beginning of 2026.
Daniel Nugent, head of portfolio development at EnergyAustralia, said: “We have already made good progress in planning the Hallett BESS, which supports South Australia’s position as a leader in clean energy generation. The project’s development and environmental planning are well advanced, and we have an ambition to expand its capacity to 150MW and 600MWh after the successful completion of stage one.”
