New South Wales is already home to several large-scale BESS, such as the Bulabul battery storage system, owned by Ampyr Australia (pictured) Image: Ampyr Australia.
Ausgrid has submitted its 150MW/300MWh Berkeley Vale Battery Energy Storage System (BESS) to the Australian government’s Environment Protection and Biodiversity Conservation (EPBC) Act for federal environmental assessment.
The project involves installing a BESS adjacent to Ausgrid’s existing Berkeley Vale Zone Substation. It is classified as a New South Wales State Significant Development (SSD).
The facility will have a maximum power output of 150MW with a 2-hour duration, equating to 300MWh of storage capacity, and will connect to the substation via a 33kV underground cable.
