How Queensland's grid-scale batteries performed in July 2026: energy and FCAS market revenue, $/MW, $/MWh, top performers, and price events.
Queensland (QLD1) batteries earned $9.85M in estimated gross energy and FCAS market revenue in July 2026, from 14 grid-scale units tracked by NEMPulse. Figures cover the full period.
Normalised across 2,870 MW and 6,763 MWh of registered capacity, the region earned $3,432/MW and $1,456/MWh for the period.
Total revenue was up 28% on June 2026, which returned $7.70M. Per MW per day — which strips out both fleet growth and the length of the window — earnings were up 26% at $111/MW/day. Optimal capture improved 14 points, from 54% to 68%.
Energy arbitrage supplied 98% of the total and FCAS 2%, with estimated Frequency Performance Payments contributing the remaining 0% ($46k). Within FCAS, regulation accounted for 73% and contingency 27%; the single largest market was raise regulation at $87k.
For context on the trading conditions, the average daily price spread (top two hours minus bottom two hours) in Queensland was $96/MWh, up 5% 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 $4.54M of unrealised upside.
On capture of the perfect-foresight energy benchmark, the strongest performers were Swanbank BESS (82%), Supernode BESS (78%), Tarong BESS (74%). At the other end: Wandoan Battery Energy Storage System (BESS) (46%), Broadsound Energy Park (27%), 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 31 days delivered 31% of everything Queensland batteries earned.
Supernode BESS led the region with $2.02M. Full dispatch, state-of-charge and bidding detail is available on each battery's page.
