Great Western Battery

The Great Western Battery involves the installation of a 500-megawatt, 1000 megawatt-hour battery at Wallerawang in NSW. The project is being developed by Neoen and will use existing network infrastructure near the decommissioned Wallerawang Power Station to connect to the national grid.

The project includes the construction of battery enclosures, inverters, transformers, and a transmission line connection to the existing Wallerawang sub-station.

The Battery will aim to provide Fast Frequency Response services to the National Electricity Market and act as a reserve to augment power supplies in the Central-West Orana Renewable Energy Zone.
