Australia has notched up a “remarkable run” on big battery investment in the first quarter of 2025, with six projects worth $2.4 billion and a combined 1,510 megawatts (MW) of capacity and more than 5 gigawatt-hours of storage duration reaching financial close in just three months.

New quarterly data from the Clean Energy Council (CEC) details a flying start to what promises to be a big year for firming, as investment dollars flow to both stand-alone battery energy storage systems (BESS) and to hybrid projects with batteries included alongside big wind and solar.

“This is the second-best quarterly result on record in terms of energy output,” the report says, and the “best annual start for new storage projects on record,” and all with the uncertainty of a federal election thrown into the mix.
