Some key details about the proposed battery energy storage system (BESS) include:  

Storage capacity: With a storage capacity of up to 400MW / 2400MWh (400MW for 6 hours), the BESS could supply electricity to over 250,000 households at times of peak demand.

Site Area: The proposed development footprint is up to 22 hectares, comprised of predominantly rural land currently used for livestock grazing. The site was carefully selected for its low environmental constraints and close proximity to existing 220kV transmission infrastructure, enabling a direct grid connection and helping to minimise additional impacts on the surrounding area. 

Project Components: The Project will include modular battery units, inverters, and grid connection infrastructure to safely store and dispatch energy to the grid via existing 220kV transmission lines that traverse the site. The facilities will also feature fire safety systems, secure access from the Princes Highway, and landscaping to support visual amenity and blend with the surrounding rural setting. 

Location: North of the Princes Highway, approximately 3km from Bunyip, in the Cardinia Shire area.
