How Queensland's grid-scale batteries performed in September 2026: energy and FCAS market revenue, $/MW, $/MWh, top performers, and price events.
Queensland (QLD1) batteries earned $383k 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 2,572 MW and 5,567 MWh of registered capacity, the region earned $149/MW and $69/MWh for the period.
Total revenue was up 66% on the same days of August 2026, which returned $230k. Per MW per day — which strips out both fleet growth and the length of the window — earnings were up 55% at $149/MW/day. Optimal capture improved 27 points, from 54% to 81%.
Energy arbitrage supplied 98% of the total and FCAS 2%, with estimated Frequency Performance Payments contributing the remaining 0% ($156). Within FCAS, regulation accounted for 92% and contingency 8%; the single largest market was raise regulation at $5k.
Against the perfect-foresight energy benchmark, Queensland batteries captured 81% of what hindsight would have earned, an estimated $89k of unrealised upside.
On capture of the perfect-foresight energy benchmark, the strongest performers were Western Downs Battery Energy Storage System (96%), Supernode BESS (92%), Supernode BESS (89%). At the other end: Chinchilla BESS, Units 1-80 (69%), Western Downs Battery Energy Storage System (BESS) (68%), Wandoan Battery Energy Storage System (BESS) (43%) — 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 $383k, and the best single battery-day was Supernode BESS on 1 Sep 2026 with $76k.
Supernode BESS led the region with $76k. Full dispatch, state-of-charge and bidding detail is available on each battery's page.
