How Queensland's grid-scale batteries performed in H2 2026: energy and FCAS market revenue, $/MW, $/MWh, top performers, and price events.
Queensland (QLD1) batteries earned $15.61M in estimated gross energy and FCAS market revenue so far in H2 2026, from 14 grid-scale units tracked by NEMPulse. Figures cover H2 2026 to date (through 15 Aug 2026).
Normalised across 2,870 MW and 6,763 MWh of registered capacity, the region earned $5,438/MW and $2,308/MWh for the period.
Total revenue was up 30% on the same days of H1 2026, which returned $12.01M. Per MW per day — which strips out both fleet growth and the length of the window — earnings were down 15% at $118/MW/day. Optimal capture improved 16 points, from 51% to 67%.
Energy arbitrage supplied 98% of the total and FCAS 2%, with estimated Frequency Performance Payments contributing the remaining 0% ($75k). Within FCAS, regulation accounted for 80% and contingency 20%; the single largest market was raise regulation at $148k.
For context on the trading conditions, the average daily price spread (top two hours minus bottom two hours) in Queensland was $102/MWh, down 38% on the previous period, and the highest spot price reached $294/MWh.
Against the perfect-foresight energy benchmark, Queensland batteries captured 67% of what hindsight would have earned, an estimated $7.19M of unrealised upside.
On capture of the perfect-foresight energy benchmark, the strongest performers were Swanbank BESS (80%), Supernode BESS (77%), Tarong BESS (71%). At the other end: Wandoan Battery Energy Storage System (BESS) (49%), Broadsound Energy Park (33%), Woolooga BESS (-8%) — 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 46 days delivered 21% of everything Queensland batteries earned.
Supernode BESS led the region with $3.22M. Full dispatch, state-of-charge and bidding detail is available on each battery's page.
