Neoen to build 219MW long-duration battery in Australia

June 21, 2023

Renewable energy producer Neoen is to build its first long-duration battery after winning a 197 MW / 4-hour capacity services contract by the Australian Energy Market Operator (AEMO) in a competitive tender initiated by the Western Australian Coordinator of Energy. 

The service will be delivered via the first stage of the 219 MW / 877 MWh Collie Battery, which consists of 224 Tesla Megapack 2XL units. 

The project, which Neoen originated in 2021, received development approval for a total of 1 GW / 4 GWh in December 2022. 

The battery is located near the town of Collie, on the country of the Wilman people of the Bibbulmun nation, in the South West region of Western Australia. It will connect to Western Power’s Shotts Terminal substation, which is part of 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) signalling the start of construction for the first stage of the Collie Battery. It is expected to be operational in Q4 2024. The battery will be Neoen’s first 4-hour long duration battery.
