Technical FAQs 4

What is the Big Canberra battery project?

The Big Canberra Battery project will deliver an ecosystem of batteries across the ACT to ensure that our electricity grid remains stable. The Big Canberra Battery project includes: The large-scale battery storage system in Williamsdale will deliver 250 megawatts (MW) of power, store renewable energy and support grid reliability.

How will battery storage affect Canberra's electricity grid?

Battery storage will play an increasing role in Canberra’s electricity grid as we move towards electrifying our city and achieving net zero emissions by 2045. Renewable energy such as wind and solar energy make electricity that large-scale batteries can store. Batteries help support the electricity grid when the sun and wind can’t.

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.

What does Williamsdale's battery storage system mean for Canberra?

The large-scale battery storage system in Williamsdale will deliver 250 megawatts (MW) of power, store renewable energy and support grid reliability. This is enough energy to power one-third of Canberra for two hours during peak demand periods. Behind-the-meter batteries were installed to help power essential services across nine government sites.
