Neoen has secured a 197 MW/4-hour capacity services contract with the Australian Energy Market Operator (AEMO), which was awarded following a competitive tender by the Western Australian Coordinator of Energy. Neoen will provide the service through its Stage 1 of Collie Battery, with a capacity of 219 MW/877 MWh and consisting of 224 Tesla Megapack 2XL units.
The AEMO Non-Co-optimised Essential System Services (NCESS) contract will provide 197 MW of storage capacity for 4 hours, charging during the day and discharging in the evening peak. This aims to address the risks identified by AEMO relating to the retirement of coal power plants and increased penetration of rooftop solar in Western Australia.
Neoen's Collie Battery, which received development approval for 1 GW / 4 GWh in December 2022, and is located near the town of Collie, will also connect to Western Power’s Shotts Terminal substation of the South-West Interconnected System. The battery is expected to be operational in Q4 2024, and it is Neoen’s first major project in the region and its first globally to have a 4-hour duration capacity.
