South Australia's SA1 trading region hit the NEM AU$20,300/MWh price cap twice on the evening of 21 June, as battery storage systems across the region captured significant revenue. The Mannum battery energy storage system (100MW/200MWh), optimised by a UK-headquartered firm, delivered the strongest performance, discharging from 21.4% to 3.2% state of charge at an average output of 15MW and generating an estimated AU$151,740. The article, sourced from NEMPulse (an independent open-data dashboard tracking grid-scale battery storage in the NEM), highlights how battery storage fleets are capitalising on extreme price volatility in the National Electricity Market.
