The Great Western Battery is a proposed 500 MW stand-alone battery in NSW.

The name was chosen due to the project’s proximity to the Great Western Highway, one of Australia’s earliest inland roads.

The battery will be able to provide a variety of services to the grid including frequency control and load shifting, which are both necessary for the development of more renewable energy.


Battery storage allows us to store the energy and reinject it into the grid whenever it’s needed.

The Great Western Battery will be located in the Lithgow region of NSW, just north of Wallerawang and about a 40 minute drive from Bathurst.

It will be linked to Transgrid’s transmission network via a substation.

Neoen has been contributing to Australia’s energy transition with 100% renewable energy since 2012.

With a balanced portfolio of wind, solar and big battery projects, we are aiming to achieve 10 GW by 2030. We own and operate all of the projects we build (rather than developing them to be sold) and as long-term neighbours we are committed to sharing the benefits with surrounding communities.

This dedication to community and environment has made us a renewable energy developer of choice in Australia.
