Neoen to build 341 MW/1,363 MWh Battery Energy Storage System in Australia

Neoen has been awarded a 300 MW / 4-hour capacity services contract by the Australian Energy Market Operator (AEMO) to build and deliver Stage 2 of Collie Battery sized at 341 MW/1,363 MWh located near the town of Collie, in the country of the Wilman people of the Bibbulmun nation, in the Southwest region of Western Australia.

The service contract was awarded in a competitive tender initiated by the Western Australian Coordinator of Energy. The Battery Energy Storage System (BESS) consisting of 348 Tesla Megapack 2 XL units will connect to Western Power’s new Palmer Terminal substation in the South-West Interconnected System (SWIS), a separate network to the one on the eastern coast of Australia.

Neoen has provided notices to proceed to Tesla and construction contractor UGL (a member of the CIMIC Group) signaling the start of construction for Stage 2 of Collie Battery, which is expected to be operational in Q4 2025. It follows on from the 219 MW/877 MWh Stage 1, which won a similar 197 MW / 4-hour contract with AEMO in June 2023 and is currently under construction and on track to start operating in Q4 2024.
