Canberra South Energy Storage Project

The Big Canberra Battery project will provide renewable energy security across the electricity grid. It will help grow the ACT's renewable energy sector, provide more local employment opportunities, and deliver a positive financial return for the territory. Building a cleaner future

The Big Canberra Battery will be capable of delivering 250 MW of power – more than a third of Canberra's peak electricity demand. It will be able to deliver this power for two hours. The Big Canberra Battery will have 500 MWh of capacity, which on a single charge could supply 23,400 households with their daily energy use.

The ACT Government has reached a major milestone in its work to future-proof Canberra's energy supply. The development application has been approved to deliver Stream 1 of the project – a grid-scale battery in Williamsdale. This ACT Government has partnered with Eku Energy on this project. Construction will begin later this year.

The Big Canberra Battery will have 500 MWh of capacity, which on a single charge could supply 23,400 households with their daily energy use. Approximately 180–200 jobs will also be created through the project. More batteries for Canberra

Batteries can store excess renewable energy to be used at later times of higher demand - thereby extending the benefit of renewable energy into the evenings. It will increase the renewable energy hosting capacity across the ACT enabling more Canberrans to access the benefits of renewables.

Energy storage is a key priority for the ACT Government as it transitions away from fossil fuels and gas and pursues its plan to reach net zero emissions by 2045. This grid-scale storage system can store as much electricity as can be generated from 25,000 average solar rooftop solar systems on an average day 2.
