Greenbank BESS (GREENB1) is a 259 MW / 400 MWh grid-scale battery energy storage system in Queensland, tracked live on NEMPulse using AEMO 5-minute dispatch data. This page shows Greenbank BESS'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 400 MWh of storage across 259 MW of power, Greenbank BESS is a 1.5-hour medium-duration battery — the 9th-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 July 2026: estimated gross energy + FCAS market revenue month-to-date $92k; capturing 44% of optimal dispatch value.
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.
