How Queensland's grid-scale batteries performed in August 2026: energy and FCAS market revenue, $/MW, $/MWh, top performers, and price events.
Queensland (QLD1) batteries earned $11.67M in estimated gross energy and FCAS market revenue in August 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 $4,173/MW and $1,893/MWh for the period.
Total revenue was up 13% on July 2026, which returned $10.30M. Per MW per day — which strips out both fleet growth and the length of the window — earnings were up 4% at $135/MW/day. Optimal capture slipped 2 points, from 72% to 70%.
Energy arbitrage supplied 98% of the total and FCAS 2%, with estimated Frequency Performance Payments contributing the remaining 0% ($69k). Within FCAS, regulation accounted for 92% and contingency 8%; the single largest market was raise regulation at $118k.
For context on the trading conditions, the average daily price spread (top two hours minus bottom two hours) in Queensland was $110/MWh, up 15% on the previous period, and the highest spot price reached $294/MWh.
Against the perfect-foresight energy benchmark, Queensland batteries captured 70% of what hindsight would have earned, an estimated $4.86M of unrealised upside.
On capture of the perfect-foresight energy benchmark, the strongest performers were Western Downs Battery Energy Storage System (83%), Supernode BESS (78%), Woolooga BESS (77%). At the other end: Chinchilla BESS, Units 1-80 (61%), Wandoan Battery Energy Storage System (BESS) (60%), Broadsound Energy Park (46%) — capture reflects strategy, contracting and constraints as much as skill, so a low figure is not automatically underperformance.
The strongest single day was 5 Aug 2026 at $702k, and the best single battery-day was Supernode BESS on 5 Aug 2026 with $157k. Revenue stays concentrated: five of the period's 31 days delivered 26% of everything Queensland batteries earned.
Supernode BESS led the region with $2.33M. Full dispatch, state-of-charge and bidding detail is available on each battery's page.
