Canberra's Williamsdale battery storage system now live on the grid
The 250 megawatt Williamsdale battery storage system is now sending energy to Australia's grid, boosting Canberra's renewable network.
Eku Energy's Williamsdale Battery Energy Storage System was turned on today after a two-year build. The facility can store enough power to supply about one-third of Canberra for two hours during peak demand, strengthening the ACT's energy security.
The Williamsdale battery contains 136 Tesla Megapacks arranged in grid clusters, connected via a transformer heavier than an ACTION bus. The battery responds to grid changes within milliseconds, storing renewable energy and releasing it when demand spikes.
The ACT government paid no upfront cost under a revenue-sharing deal and will receive about 20 to 25 million dollars a year. Chief Minister Andrew Barr said it was the first of more storage projects to come as Canberra electrifies faster than anywhere else in the country.

Why it mattersAs homes, vehicles and heating switch to electric power, batteries store renewable energy to prevent blackouts. This battery strengthens that system.
AustraliaCanberra households and businesses get more reliable power during peak periods. The ACT is aiming for net zero emissions by 2045, and this battery is central to that plan.
