Ballarat Battery Energy Storage System (BALB1) is a 30 MW / 30 MWh grid-scale battery energy storage system in Victoria, tracked live on NEMPulse using AEMO 5-minute dispatch data. This page shows Ballarat Battery Energy Storage System'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 30 MWh of storage across 30 MW of power, Ballarat Battery Energy Storage System is a 1.0-hour short-duration battery — the 12th-largest of 15 grid-scale batteries in Victoria 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 $5k; capturing 38.1% 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.
