Battery storageProject Ballarat Energy Storage System (BESS)
This is the final knowledge sharing report for the Ballarat Energy Storage System (BESS). It outlines the performance and key learnings over the first 24 months of operation.
The project is the first of its kind in Australia — a standalone battery-based energy storage system being installed in front of the meter and directly connected to the transmission network — and the first grid-scale battery-based storage system commissioned in the state of Victoria.
The Ballarat System is a 30MW / 30MWh system utilising Lithium-ion battery technology and Fluence’s proprietary hardware and software controls. The system is installed at Ballarat Terminal Station (BATS) and is connected to the transmission network via the BATS No.1 transformer tertiary winding (rated at 22kV 40MVA). The Ballarat System is registered to operate as a 30MW generator, a 30MW load, and to provide regulation Frequency Control Ancillary Services (FCAS) raise and lower as well as all six contingency FCAS markets. The Ballarat Terminal Station is the central hub for the electricity transmission network in western Victoria and the location was chosen to add new capabilities at AusNet Services’ existing facility to support further renewable electricity generation, in addition to over 620MW of existing local renewable energy generation.
