A new battery energy storage system (BESS) project has been proposed in Collie, Western Australia, featuring an on-site collector substation and two 330/33kV transformers, along with a 2km underground 330kV transmission cable to connect to Western Power's Palmer Terminal Station. The project area spans close to 180 hectares, with a disturbance footprint of 98.47 hectares, which will involve the removal of potential nesting trees but retain over 80 hectares of native vegetation.

This proposal adds to Collie's growing energy storage infrastructure, including Neoen's 2.2GWh battery, which significantly boosted the company's profitability in 2024. Synergy's 2,000MWh battery system has also been highlighted by Prime Minister Anthony Albanese. The region is experiencing rapid energy infrastructure development, with Tesla exploring a battery re-manufacturing facility for Asia-Pacific operations.
