Suitable energy storage project sites are quickly being snapped up in Australia’s National Electricity Market (NEM), with a premium on grid location.  

On day one of the Energy Storage Summit Australia 2025, the audience heard that although 2 to 4-hour duration battery energy storage systems (BESS) are favourable, longer durations are starting to challenge this.

Ahead of the Energy Storage Summit Australia 2025, which will take place next week (18-19 March) in Sydney, we take a look at some of the key debates set to take centre stage at the event.

ACEnergy has submitted a 400MW/1,760MWh BESS to the Australian government’s Environment Protection and Biodiversity Conservation (EPBC) Act.

Modo Energy has said that revenue for BESS in Australia’s NEM fell by 7% month-on-month in January, despite revenue tripling in Queensland.

Gold Green Energy has secured consent for a 400MWh solar-plus-BESS site, whilst AEMO has seen 18.1GW of BESS seeking a connection to the NEM.

Modo Energy has said that battery energy storage systems (BESS) in Australia’s National Electricity Market (NEM) earned an average of AU$148,000/MW (US$92,810/MW) in 2024, a 45% increase year-on-year.

Modo Energy’s Wendel Hortop tells Energy-Storage.news that over 4GW of utility-scale BESS on the NEM will be in commercial operation by 2025.

Copenhagen Infrastructure Partners (CIP) has issued notice to proceed for Summerfield large-scale battery storage project in South Australia.

Eku Energy’s chief technology officer, Elias Saba, discusses the shift in economics of long-duration BESS in Australia’s NEM.
