Eku Energy to develop 250MW Australian battery

April 14, 2023

The Australian Capital Territory Government in Canberra has entered into a “long-term partnership” with Macquarie’s Green Investment Group global specialist energy storage team, Eku Energy, to develop the next stage of the Big Canberra Battery with a large-scale battery storage facility in Williamsdale.

The 250MW, 500MWh battery energy storage system is expected to store enough renewable energy to power one-third of Canberra for two hours during peak demand periods.

The storage system will cost between $300 and $400 million to build and will be developed, built and operated by Eku Energy. Construction will start in late 2024 with completion expected in 2025.
