The Energy Storage Initiative supports and assists energy storage technologies and projects that improve the reliability of the Victorian electrical system, drive the development of clean technologies, and boost the local economy.

Supporting the integration of energy storage is one of the actions outlined in the Renewable Energy Action Plan, released in July 2017.

The $25 million Energy Storage Initiative was announced by the Premier, and the Minister for Energy, Environment and Climate Change in 2017, and in March 2018, two projects to build commercially-ready battery storage in western Victoria were selected.

The Projects

The two projects selected under the Energy Storage Initiative include:

Ballarat Energy Storage System

Spotless Sustainability Services are leading a consortium to build a 30 megawatt (MW) / 30 megawatt hour (MWh) battery at the Ballarat Terminal Station. The project will connect directly to an integral part of the electricity grid network. This project will provide crucial power supply, frequency control, and back-up services to support the network.

The battery system is being supplied by Fluence, will be owned by AusNet Service, and operated by Energy Australia.

See Spotless Sustainability Services' website for more information

Gannawarra Energy Storage System

Edify Energy are delivering a 25MW/50MWh battery co-located with the Gannawarra Solar Farm. This project will demonstrate the potential to pair battery storage with solar farms behind the meter to produce less variable and more consistent energy supply. Once completed, this project will be the largest integrated solar farm and battery project in Australia, and among the largest in the world. This battery is able to store 100% renewable energy since it is located behind the meter of the solar farm.

The battery will be a Tesla Powerpack system, jointly owned by Edify Energy and Wirsol Energy, and operated by EnergyAustralia.
