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


No it’s not in Western Australia ! This NSW battery is named after the Great Western Highway which runs just to the south of the site. It is the main highway linking Sydney to Bathurst.

The road’s history dates back to early colonial times – in 1792 the first overland track from Sydney to Parramatta was formed, along what is now the Parramatta Road.

In the early 1800’s a number of expeditions found routes through the Blue Mountains, and by 1815 the road had reached Bathurst and was given the name the Great Western Road by Governor Macquarie.


The NSW Government is committed to a clean energy transition and has set a target for achieving zero emissions by 2050.

In November 2020 they released the NSW Electricity Infrastructure Roadmap, part of the strategy is to establish Renewable Energy Zones (REZ’s) including one in the Central West.

It is hoped that the Great Western Battery can play its part in supporting the NSW Government to achieve a smooth transition.


The Great Western Battery is a grid-scale battery that will connect into Australia’s national 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 Great Western Battery will provide stability for the region by dispatching stored energy to the grid during peak times of demand.

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.
