6 FAQs about [Canberra completes energy storage power station]
Is Canberra building a big battery in Williamsdale?
The ACT Government is building a big battery in Williamsdale. Construction has begun, in partnership with Eku Energy. This project is part of larger efforts to make Canberra a cleaner, greener city. Construction has begun the Williamsdale Battery Energy Storage System (BESS).
How much power will the Big Canberra battery deliver?
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.
What is the Big Canberra battery project?
Through this, three medium-sized neighbourhood-scale batteries will be installed in Casey, Dickson and Fadden. A battery operator will be selected in late 2024 following a procurement process. The Big Canberra Battery project will provide renewable energy security across the electricity grid.
When will a solar battery be operational in Canberra?
The battery is expected to be operational in 2026 and will be able to store enough renewable energy to power one-third of Canberra for two hours during peak demand periods.
Will Canberra's energy supply be future-proof?
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.
What is Williamsdale battery energy storage system?
It will store enough renewable energy to power one-third of Canberra for two hours during peak demand. Image: ACT Government. The $300-400 million Williamsdale Battery Energy Storage System will plug into the ACT electricity grid from early 2026, with construction now underway on the site adjacent to the solar farm.
