Ballarat Energy Storage System

AusNet Services is hosting a 30 Megawatt (MW) 30 Megawatt-hour (MWh) Battery Energy Storage System which is to be installed at the Ballarat Terminal Station in Warrenheip, Victoria. The world-class consortium comprising Spotless, AusNet Services, EnergyAustralia and Fluence, was  commissioned by the Victorian Government and the Australian Renewable Energy Agency (ARENA) to design, construct and operate Victoria’s first utilities scale grid-connected Battery Energy Storage System. AusNet Services will own the Ballarat Energy Storage System.


This 33-million-dollar project is Victoria’s first utilities scale Lithium-Ion battery storage system, which once complete will be the size of nine shipping containers and have the capacity to power more than 20,000 homes for an hour before being recharged.

As the battery is within AusNet Services Ballarat Terminal Station, it will be fully integrated into the electricity grid, where it will contribute to meeting peak energy demand. It will also help to enhance the stability and security of the State's energy supply.


Approximate dates for the project program are as follows:
