AEMO has revealed a big increase in battery energy storage system (BESS) output in Australia’s National Electricity Market (NEM).

New UL9540A test aims to further enhance battery storage fire safety, while large-scale fire testing (LSFT) aims to address remaining gaps.

A 238.5MW/477MWh standalone battery energy storage system (BESS) has been commissioned in South Australia, and an optimisation deal signed for another of the state’s largest BESS assets.

Queensland achieved a new battery discharge record on 30 March 2025, with a maximum instantaneous battery discharge of 474.1MW at 17:55.
