Stanwell Battery Energy Storage System (STABESS1) is a 317 MW / 1200 MWh grid-scale battery energy storage system in Queensland, tracked live on NEMPulse using AEMO 5-minute dispatch data. This page shows Stanwell Battery Energy Storage System's energy arbitrage and FCAS revenue, state of charge, dispatch profile, bidding behaviour, and actual-vs-optimal performance in the Australian National Electricity Market (NEM).
With 1200 MWh of storage across 317 MW of power, Stanwell Battery Energy Storage System is a 3.8-hour long-duration battery — the 5th-largest of 17 grid-scale batteries in Queensland by registered power. Duration sets how long it can sustain full output, and with it how much of the daily price spread it can arbitrage before running flat.
As of 6 Aug 2026: estimated gross energy + FCAS market revenue month-to-date $-122.
Price and dispatch are measured AEMO values; energy and FCAS revenue are derived from them; FPP revenue and integrated state of charge are estimated. See the provenance scheme on the methodology page.
