Australia becomes the ‘world’s third-largest utility-scale battery storage market’

AI-summarised brief · reviewed before publication

Australia has become the world's third-largest utility-scale battery storage market, with 4.3GW of large-scale battery storage systems reaching financial close in 2025. The country now ranks behind only the US and China in utility-scale battery storage deployment. Investment in storage remained robust throughout 2025, with 2GW/5.1GWh of battery energy storage systems commissioned, representing a 233% year-on-year increase. Renewables now comprise approximately 43% of Australia's grid, creating an urgent need for technologies to manage system security. A growing share of the battery storage pipeline includes grid-forming capability, enabling systems to provide synthetic inertia and support system strength.
