Australia’s 55 grid-scale battery energy storage systems (BESS) tracked by NEMPulse generated a combined AU$17.98 million (US$12.43 million) in estimated gross energy and frequency control ancillary services (FCAS) market revenue during June 2026.

NEMPulse is an independent, open-data dashboard that tracks the dispatch, revenue, and bidding behaviour of every grid-scale battery storage system in the National Electricity Market (NEM).

Normalised across the fleet’s 7,960MW and 18,961MWh of active capacity, battery storage systems earned AU$2,000 per MW and AU$948 per MWh for the period, equivalent to AU$27,000 per MW annualised.
