Battery energy storage systems in Australia’s NEM are facing new operational and revenue challenges due to minimum system load events.

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.

Tesla has announced that by the end of 2026, it expects to have around 4.5GW of grid-forming battery storage operating across Australia.

ESN Premium speaks with Michael Bennett, chief transformation officer at Powin, about battery management and state-of-charge.

A reduction in price volatility has seen BESS revenue decrease by 40% in Australia’s NEM month-on-month in March 2025.

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.

The start of 2025 has seen new and updated BESS revenue indexes launched for Germany as well as other other European markets, by optimiser enspired and consultancies Clean Horizon, Aurora Energy Research and LCP Delta.

Modo Energy has signalled that 16.8GW of battery energy storage systems (BESS) will connect to Australia’s National Electricity Market (NEM) by the end of 2027.
