Grid Stability for ACT

Neoen Australia

We own and operate SA’s big battery

Sharing Benefits

Making a difference in local communities


The Capital Battery is a 100MW stand-alone battery capable of storing up to 200MWh 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.

Capital Battery Canberra


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.
