Victorian Big Battery (VBB1) is a 360 MW / 450 MWh grid-scale battery energy storage system in Victoria, tracked live on NEMPulse using AEMO 5-minute dispatch data. This page shows Victorian Big Battery'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 450 MWh of storage across 360 MW of power, Victorian Big Battery is a 1.3-hour short-duration battery — the largest of 15 grid-scale batteries in Victoria 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 $52k; capturing 32% 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.
