Neoen acknowledges the Whadjuk people, Traditional Owners of the land on which Muchea Battery will store energy. We pay our respects to their Elders past and present.


The name – Muchea – has been given to the project as it is very close to the town of Muchea. The town’s name comes from the Aboriginal word “Muchela” which means in Nyoongar ‘water hole’, referring to the abundance of water in Muchea.

The location was selected based on it’s proximity to the grid and to the existing industrial area. The land on which the battery will be constructed is relatively flat and has no potential risk to the ecological communities.


The battery will support increased amounts of renewable energy in WA by providing grid services – storing low cost energy when the sun is shining and wind is blowing for releasing at times when its needed most, and through helping to deliver a more secure and modern energy system.


The Muchea Battery is a grid-scale battery that will connect into Western Australia’s electricity grid via the transmission network.

At this early stage in the project’s development no decision has been made about which of a number of leading battery technologies will be used.

Whichever battery technology is chosen, the Muchea Battery will provide stability for the region by dispatching stored energy to the grid during peak times of demand.


Umwelt are an environmental consultancy who are helping Neoen with environmental and social studies and development approvals for the project. Studies completed or underway are related to water (surface and groundwater), noise, visual, flora and vegetation, bushfire, and traffic.

These studies will be used to ensure the project addresses key environmental and planning needs.


Neoen are leading the way in delivering big batteries in Australia and around the world.

Neoen’s 150MW Hornsdale Power Reserve , more commonly as the ‘Tesla Big Battery’, has been keeping the lights on and electricity costs low for South Australians, since 2017.

Our 300MW Victorian Big Battery, currently under construction near Geelong, will be one of the world’s largest batteries.
