Clements Gap BESS (CGBESS01) is a 91 MW / 120 MWh grid-scale battery energy storage system in South Australia, tracked live on NEMPulse using AEMO 5-minute dispatch data. This page shows Clements Gap 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 120 MWh of storage across 91 MW of power, Clements Gap BESS is a 1.3-hour short-duration battery — the 10th-largest of 18 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 29 Oct 2026: estimated gross energy + FCAS market revenue month-to-date $532k; capturing 70.8% 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.
