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 $33.54M in estimated gross energy and FCAS market revenue in Q3 2026, from 16 grid-scale units tracked by NEMPulse. Figures cover the full period.
Normalised across 2,796 MW and 6,164 MWh of registered capacity, the region earned $12k/MW and $5,441/MWh for the period.
Total revenue was up 41% on Q2 2026, which returned $23.78M. Per MW per day — which strips out both fleet growth and the length of the window — earnings were up 34% at $130/MW/day. Optimal capture improved 11 points, from 59% to 70%.
Energy arbitrage supplied 98% of the total and FCAS 2%, with estimated Frequency Performance Payments contributing the remaining 0% ($181k). Within FCAS, regulation accounted for 73% and contingency 27%; the single largest market was raise regulation at $319k.
For context on the trading conditions, the average daily price spread (top two hours minus bottom two hours) in Queensland was $107/MWh, up 8% on the previous period, and the highest spot price reached $446/MWh.
Against the perfect-foresight energy benchmark, Queensland batteries captured 70% of what hindsight would have earned, an estimated $13.53M of unrealised upside.
On capture of the perfect-foresight energy benchmark, the strongest performers were Western Downs Battery Energy Storage System (81%), Supernode BESS (78%), Swanbank BESS (75%). At the other end: Woolooga BESS (52%), Broadsound Energy Park (50%), Stanwell Battery Energy Storage System (-56%) — 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 $920k, and the best single battery-day was Supernode BESS on 30 Jul 2026 with $182k. Revenue stays concentrated: five of the period's 92 days delivered 10% of everything Queensland batteries earned.
Supernode BESS led the region with $6.51M. Full dispatch, state-of-charge and bidding detail is available on each battery's page.
Queensland saw one price event this period, negative pricing bottoming at $-246/MWh.
