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


The Capital Battery is a 100 MW stand-alone battery capable of storing up to 200 MWh of energy with up to 2 hours of power in reserve.

50 MW was committed as part of the ACT Government’s 2020 renewable energy auction, with a further 50 MW yet to be contracted.

The battery will provide a predictable supply of electricity to the grid through its ability to dispatch energy during peak times of demand.


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

The Capital Battery will be located in the ACT, just north of the Queanbeyan substation.

This is approximately 3km south of Fyshwick and 3km north of Queanbeyan.

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

These big batteries mean that our small jurisdiction is again punching above our weight when it comes to real climate action. Our investment is on par with the Tesla Hornsdale battery on a per capita basis – the largest investment of its kind in the world.

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.
