How New South Wales's grid-scale batteries performed in September 2026: energy and FCAS market revenue, $/MW, $/MWh, top performers, and price events.
New South Wales (NSW1) batteries earned $232k in estimated gross energy and FCAS market revenue so far in September 2026, from 14 grid-scale units tracked by NEMPulse. Figures cover September 2026 to date (through 1 Sep 2026).
Normalised across 2,199 MW and 7,719 MWh of registered capacity, the region earned $106/MW and $30/MWh for the period.
Energy arbitrage supplied 100% of the total and FCAS 0%. Within FCAS, regulation accounted for 92% and contingency 8%; the single largest market was raise regulation at $689.
Against the perfect-foresight energy benchmark, New South Wales batteries captured 76% of what hindsight would have earned, an estimated $71k of unrealised upside.
On capture of the perfect-foresight energy benchmark, the strongest performers were New England BESS (94%), Smithfield Battery Energy Storage System, Units 1 - 36 (92%), Limondale Battery (91%). At the other end: Capital Battery (66%), Eraring Battery Energy Storage System (0%), Liddell Battery Energy Storage System (0%) — capture reflects strategy, contracting and constraints as much as skill, so a low figure is not automatically underperformance.
The strongest single day was 1 Sep 2026 at $232k, and the best single battery-day was Orana BESS on 1 Sep 2026 with $124k.
Orana BESS led the region with $124k. Full dispatch, state-of-charge and bidding detail is available on each battery's page.
