About the project
The Liddell Battery is a 500 MW, two-hour duration, grid scale battery to be located on the former Liddell Power Station site at AGL Macquarie.
Construction work for the battery has commenced in June 2024, with the commencement of operations targeted for December 2025. Significant targets have been set around the employment of apprentices, local procurement – including 95% of steel being sourced locally - and working with First Nations businesses. At the peak of construction more than 150 workers will be involved in the project.
The total construction cost is estimated to be approximately $750 million. Fluence has been selected as the engineering, procurement and construction (EPC) contractor. Connection Agreements have been signed with Transgrid to construct and operate 330/33kV battery substation and ~450mtrs of 330kV overhead transmission line and an extension to the existing 330kV switch yard.
The project will be 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.
This will be the first new development to be built as part of our Hunter Energy Hub after Liddell was safely and respectfully retired in April 2023.
