Ballarat Battery Energy Storage System

The world-class consortium comprising Spotless, AusNet Services, EnergyAustralia and Fluence, has been 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.

The 30 Megawatt (MW) 30 Megawatt-hour (MWh) Battery Energy Storage System will be located at the AusNet Services Ballarat Terminal Station in Warrenheip, Ballarat. The system will comprise nine purpose-built and engineered battery enclosures (similar to a standard shipping container) for its Lithium–Ion batteries, operating system and environmental controls, security and associated cooling and safety systems.

Spotless Sustainability Services will manage the design and construction of this landmark project. They will commission the Battery Energy Storage System from Fluence, the recognised energy storage global leader. The system will be an unregulated asset of AusNet Services and will be installed at its Ballarat Terminal Station and connected to its electricity transmission network. Once the system has been commissioned and accepted by AusNet Services and the Australian Energy Market Operator (AEMO), EnergyAustralia will operate the charge and discharge of the system.
