Technical FAQs 4

Will a big battery power Canberra?

The government said the big battery project will be capable of responding rapidly to network constraints and will be able to store enough renewable energy to power one-third of Canberra for two hours during peak demand periods. The Williamsdale battery will be developed, built and operated by Macquarie Group offshoot Eku Energy.

How will the Big Canberra battery project work?

Selection of the battery operator will be made in late 2024 following a procurement process. The Big Canberra Battery project will provide renewable energy security across the electricity grid, help the ACT grow its renewable energy sector, provide more local employment opportunities, and deliver a positive financial return for the Territory.

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.

Why is the Big Canberra battery a significant milestone for EKU energy?

Quote attributable to Eku Energy CEO, Dan Burrows: "The Big Canberra Battery represents a significant milestone for Eku Energy as it marks our first GWh of projects in delivery in Australia. We are proud to be working in partnership with the ACT Government to deliver the development of the first stream of the Big Canberra Battery.
