Ballarat Energy Storage System

The Ballarat Battery Energy Storage System (BESS) is Victoria’s first utilities scale grid-connected battery.  




Overview

The Ballarat BESS is a 30MW/30MWhr battery. It was integrated into the electrical grid in 2018.  

Our battery has the capacity to power over 20,000 homes for more than an hour before being recharged. It’s located in the Ballarat Terminal Station. This allows us to help Victoria meet peak energy demand and improve the stability of the state’s energy supply. 

The project was commissioned by the Victorian Government and Australian Renewable Energy Agency (ARENA). The Ballarat BESS was designed, constructed, and is now operated with our help from our partners Spotless, EnergyAustralia and Fluence.
