Publicly-owned energy company CleanCo Queensland’s 250MW/500MWh Swanbank battery energy storage system (BESS) has officially registered with AEMO and commenced its testing and commissioning phase.

Developer Epic Energy has commenced commercial operations at its 100MW/200MWh Mannum battery energy storage system (BESS) in South Australia.

Battery storage equipped with optimisation platforms not specifically designed for Australia’s NEM missed revenue opportunities during the 10 October price spike, according to Sahand Karimi, co-founder and CEO of OptiGrid.

Australia’s most powerful BESS, the 850MW Waratah Super Battery, achieved its first full discharge to the NEM last week.

Queensland’s Energy Roadmap 2025 suggests that by 2030, up to 4.3GW of short-duration energy storage could be operational.

On 10 October, electricity prices in New South Wales, Australia, reached the Market Price Cap of AU$20,300/MWh (US$13,307/MWh).

The New South Wales Independent Planning Commission has approved ACEnergy’s 250MW/1,100MWh Yanco battery energy storage system in Australia.

Australia has announced the results of the fourth Capacity Investment Scheme tender, with 11.4GWh of solar-plus-storage contracts awarded.

South Australia is set to open a tender seeking 700MW of long-duration energy storage to bolster grid reliability.

Battery energy storage revenues in Australia’s National Electricity Market (NEM) fell 61% in September 2025 to AU$85,000/MW (US$56,712/MW) as price volatility eased across the grid, according to new research from Modo Energy.
