Collie Battery is Neoen’s first 4-hour long duration battery & its first major project in Western Australia. The project has development approval for 1 GW / 4 GWh.

Collie Battery is currently being built in stages, two of which are currently under construction: 

  • Stage 1 is sized at 219 MW / 877 MWh 
  • Stage 2 is sized at 341 MW / 1,363 MWh

Once operational, Collie Battery will be able to provide short duration storage in peak times to ease pressure on the grid. It will have the ability to charge and discharge 20% of the average demand in Western Australia’s South-West Interconnected System (SWIS).


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

Collie Battery is located approximately 13 km north-east of the town of Collie, 4km north-east of the Collie Power Station in the Southwest region of Western Australia.

It will connect into Western Power’s new Palmer Terminal substation in the SWIS.

Project Lifecycle

Shire of Collie representative Councillor Ian Miffling said the DA proposal was supported by the shire – “It’s been very well presented to the council and the community — there has been a good process.”

Get Involved

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.
