How Queensland's grid-scale batteries performed in Q3 2026: energy and FCAS market revenue, $/MW, $/MWh, top performers, and price events.
Queensland (QLD1) batteries earned $25.70M in estimated gross energy and FCAS market revenue so far in Q3 2026, from 14 grid-scale units tracked by NEMPulse. Figures cover Q3 2026 to date (through 11 Sep 2026).
Normalised across 2,792 MW and 6,156 MWh of registered capacity, the region earned $9,206/MW and $4,175/MWh for the period.
Total revenue was up 36% on the same days of Q2 2026, which returned $18.85M. Per MW per day — which strips out both fleet growth and the length of the window — earnings were up 17% at $126/MW/day. Optimal capture improved 10 points, from 59% to 68%.
Energy arbitrage supplied 98% of the total and FCAS 2%, with estimated Frequency Performance Payments contributing the remaining 0% ($140k). Within FCAS, regulation accounted for 84% and contingency 16%; the single largest market was raise regulation at $248k.
For context on the trading conditions, the average daily price spread (top two hours minus bottom two hours) in Queensland was $103/MWh, broadly flat on the previous period, and the highest spot price reached $294/MWh.
Against the perfect-foresight energy benchmark, Queensland batteries captured 68% of what hindsight would have earned, an estimated $11.46M of unrealised upside.
On capture of the perfect-foresight energy benchmark, the strongest performers were Supernode BESS (78%), Swanbank BESS (77%), Western Downs Battery Energy Storage System (72%). At the other end: Wandoan Battery Energy Storage System (BESS) (50%), Broadsound Energy Park (47%), Stanwell Battery Energy Storage System (-114%) — capture reflects strategy, contracting and constraints as much as skill, so a low figure is not automatically underperformance.
The strongest single day was 30 Jul 2026 at $900k, and the best single battery-day was Supernode BESS on 30 Jul 2026 with $183k. Revenue stays concentrated: five of the period's 73 days delivered 13% of everything Queensland batteries earned.
Supernode BESS led the region with $5.22M. Full dispatch, state-of-charge and bidding detail is available on each battery's page.
