Neoen scales up 270 MW/540 MWh Battery storage project in Australia

Neoen has expanded its Western Downs Battery, located in Barunggam country near the town of Chinchilla in South West Queensland, Australia. The Project which is currently under construction has a total installed capacity of 270 MW / 540 MWh. 

The extension project will be delivered by Tesla and construction contractor UGL (a member of the CIMIC Group) who commenced construction of the initial stage of the project in January 2023. 

Western Downs Battery, consisting of Tesla Megapack 2XL units, leverages the existing infrastructure of Neoen's Western Downs Green Power Hub. The Hub includes Australia's largest solar farm at 460 MWp capacity, which has recently been commissioned. Queensland's transmission network operator Powerlink will be delivering the project's connection works and a dedicated high-voltage line into the Western Downs substation. The battery is expected to start operating in the Australian summer of 2024/25.
