South Hummocks BESS

RWE Renewables Australia is proposing to construct a standalone, lithium-ion Battery Energy Storage System (BESS) at South Hummocks in South Australia, about 125 kilometres north-west of Adelaide in the Barunga West Council.

The proposed project site consists of 56 hectares of private land zoned rural under the South Australian Planning, Development and Infrastructure Act 2016. It is currently used for cereal cropping and is situated close to existing grid infrastructure. The proposed BESS would have a maximum capacity of 80 megawatts (MW) and 320 megawatt hours (MWh).

The BESS would connect to the Kadina East 132kV line, via the Hummocks substation.

As part of this project, RWE will be engaging with the local community to develop lasting partnerships.

Project benefits

The proposed South Hummocks BESS aims to improve the reliability and security of the electricity network by storing energy during periods of low demand, and dispatching energy during periods of peak demand and emergency events. The BESS would be a key piece of infrastructure in supporting energy storage development in regional Australia and would subsequently assist in reducing emissions by improving national resilience in energy supply and supporting affordable energy for Australian homes.

The project would also create job opportunities, with an estimated 80 full-time equivalent jobs during the up to 24-month construction period and up to three ongoing positions during operations.
