Eraring Battery Energy Storage System 2 (ERB02) is a 351 MW / 1390 MWh grid-scale battery energy storage system in New South Wales, tracked live on NEMPulse using AEMO 5-minute dispatch data. This page shows Eraring Battery Energy Storage System 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 1390 MWh of storage across 351 MW of power, Eraring Battery Energy Storage System 2 is a 4.0-hour long-duration battery — the 5th-largest of 18 grid-scale batteries in New South Wales 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 1 Sept 2026: estimated gross energy + FCAS market revenue month-to-date $715; capturing 14.7% 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.
