Collie Battery is Neoen’s first 4-hour long duration battery & its first major project in Western Australia. Stage 1 of Collie Battery, sized at 219 MW / 877 MWh, is currently under construction.

The project has development approval for 1 GW / 4 GWh and is located near the town of Collie.

Once operational, Collie Battery will be able to provide short duration storage in peak times to ease pressure on the grid. It will offer grid stability and other services which will encourage integration of more renewable energy into the electricity network.


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

The Collie Battery will be is located approximately 13km north-east of Collie – 4km north-east of the Collie Power Station.

It will connect into the Shotts Terminal substation at 330kV. The proximity to the substation minimises electrical connection infrastructure, increasing performance and reducing costs.


For western Australia

More renewables, reliable power, has the capacity to lower energy costs

For regional economy

Regional jobs & supply chain opportunities

For local community

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.”

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.
