4 FAQs about Canberra Low Voltage Energy Storage Project

What is the Big Canberra battery project?

The ACT Government is committed to achieving a net zero emissions future. To reach this goal, the Big Canberra Battery project will see a network of batteries constructed across the ACT. A key project within this network is the Williamsdale Battery Energy Storage System (BESS), which will be built and operated by Eku Energy.

How many megawatts will a battery deliver in Canberra?

The Government says the battery will deliver at least 250 megawatts of power, enough stored renewable energy to supply one-third of Canberra for two hours during peak demand.

Will Canberra's big Canberra battery keep the lights on?

“The Big Canberra Battery will keep the lights on while driving down emissions, giving Canberrans confidence that clean energy can meet our needs well into the future,” said ACT Chief Minister, Andrew Barr.

What is the Big Canberra battery transformer?

The ACT Government has taken delivery of its Big Canberra Battery transformer, which is set to ensure stored electricity is converted to the correct voltage to be safely supplied to the grid.
