Summerfield BESS 2 (SMFBESS2) is a 154 MW / 480 MWh grid-scale battery energy storage system in South Australia, tracked live on NEMPulse using AEMO 5-minute dispatch data. This page shows Summerfield BESS 2'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 480 MWh of storage across 154 MW of power, Summerfield BESS 2 is a 3.1-hour long-duration battery — the 5th-largest of 17 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.
As of 6 Aug 2026: estimated gross energy + FCAS market revenue month-to-date $-299.
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.
