The Hallett Battery Energy Storage System (BESS) will be constructed on the traditional country of the Ngadjuri People. We recognise their continued connection to land, waterways and community and we pay our respects to Elders past and present.

EnergyAustralia is planning to develop the Hallett Battery Energy Storage System (BESS) alongside its Hallett gas-fired power station, in Canowie, 210km north of Adelaide.

This grid-scale battery would have an initial storage capacity of 50MW and discharge capacity of up to 200MWh.  It will be able to power up to 81,000 homes and small businesses for four hours.  There are plans to triple its capacity to 150MW in a future second stage.

The battery project has received Crown Sponsorship and declared as critical infrastructure by the South Australian Department of Energy and Mining.

Developing the battery on EnergyAustralia land, alongside our gas-fired power station, means the project will use the existing transmission infrastructure and connection to the grid. This substantially minimises the project's impact on the surrounding environment.

We anticipate the battery will be ready and storing excess energy generated by renewables by the end of 2026.
