Phillip Island BESS (PIBESS1) is a 7 MW / 12 MWh grid-scale battery energy storage system in Victoria, tracked live on NEMPulse using AEMO 5-minute dispatch data. This page shows Phillip Island 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 12 MWh of storage across 7 MW of power, Phillip Island BESS is a 1.7-hour medium-duration battery — the 17th-largest of 18 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 1 Oct 2026: estimated gross energy + FCAS market revenue month-to-date $-1k; capturing -138.2% 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.
