The first of its kind 100MW Tesla lithium-ion battery began operating back in late 2018 and its fed power from nearby Hornsdale wind farm. 

Neoen have also announced further battery storage projects including coupling an existing 194MW wind farm to a major storage facility as well as the proposal of a 50MW storage facility in Queensland.
