About the project
The Liddell Battery is a 500 MW, two-hour duration, grid scale battery located on the former Liddell Power Station site.
Construction of the battery is complete, with commissioning of the first 250 MW underway, and the battery expected to slowly ramp up to full commercial operations by June 2026. Significant targets were set around the employment of apprentices and local procurement – with locally sourced steel used for construction such as fences and steel rods in concrete and a First Nations business involved in construction. More than 600 workers have contributed to the construction and commissioning of the battery.
The total construction cost was approximately $750 million, with Fluence as the engineering, procurement and construction (EPC) contractor. Transgrid has constructed and operates a 330/33kV battery substation, and~450mtrs of 330kV overhead transmission line and an extension to the existing 330kV switch yard.
The project is supported by both a $35 million grant awarded by the Australian Renewable Energy Agency (ARENA) as part of its Advancing Renewables Program and a Long-Term Energy Service Agreement (LTESA), arranged by AEMO Services on behalf of the NSW Government.
