Tailem Bend 3 BESS (TB3B1) is a 263 MW / 526 MWh grid-scale battery energy storage system in South Australia, tracked live on NEMPulse using AEMO 5-minute dispatch data. This page shows Tailem Bend 3 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 526 MWh of storage across 263 MW of power, Tailem Bend 3 BESS is a 2.0-hour medium-duration battery — the 2nd-largest of 18 grid-scale batteries in South Australia 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.
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.
