Tarong BESS (TARBESS1) is a 393 MW / 600 MWh grid-scale battery energy storage system in Queensland, tracked live on NEMPulse using AEMO 5-minute dispatch data. This page shows Tarong 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 600 MWh of storage across 393 MW of power, Tarong BESS is a 1.5-hour medium-duration battery — the largest of 17 grid-scale batteries in Queensland by registered power, and one of the ten largest in the NEM. 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 $184k; capturing 67% 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.
