How Queensland's grid-scale batteries performed in H1 2026: energy and FCAS market revenue, $/MW, $/MWh, top performers, and price events.
Queensland (QLD1) batteries earned $47.34M in estimated gross energy and FCAS market revenue in H1 2026, from 15 grid-scale units tracked by NEMPulse. Figures cover the full period.
Normalised across 2,694 MW and 6,411 MWh of registered capacity, the region earned $18k/MW and $7,385/MWh for the period.
Total revenue was broadly flat on H2 2025, which returned $46.53M. Per MW per day — which strips out both fleet growth and the length of the window — earnings were down 28% at $97/MW/day. Optimal capture slipped 10 points, from 69% to 59%.
Energy arbitrage supplied 90% of the total and FCAS 9%, with estimated Frequency Performance Payments contributing the remaining 1% ($406k). Within FCAS, regulation accounted for 28% and contingency 72%; the single largest market was lower 6-second at $1.43M.
For context on the trading conditions, the average daily price spread (top two hours minus bottom two hours) in Queensland was $115/MWh, down 37% on the previous period, and the highest spot price reached $19,728/MWh.
Against the perfect-foresight energy benchmark, Queensland batteries captured 59% of what hindsight would have earned, an estimated $28.78M of unrealised upside.
On capture of the perfect-foresight energy benchmark, the strongest performers were Western Downs Battery Energy Storage System (75%), Brendale BESS (70%), Western Downs Battery Energy Storage System (BESS) (63%). At the other end: Supernode BESS (50%), Chinchilla BESS, Units 1-80 (48%), Broadsound Energy Park (-34%) — capture reflects strategy, contracting and constraints as much as skill, so a low figure is not automatically underperformance.
The strongest single day was 15 Jan 2026 at $2.28M, and the best single battery-day was Supernode BESS on 15 Jan 2026 with $545k. Revenue stays concentrated: five of the period's 181 days delivered 10% of everything Queensland batteries earned.
2 batteries earned their first market revenue in the period — Supernode BESS, Stanwell Battery Energy Storage System — adding 560 MW of earning capacity.
Western Downs Battery Energy Storage System (BESS) led the region with $6.88M. Full dispatch, state-of-charge and bidding detail is available on each battery's page.
Queensland saw 2 price events this period, the sharpest an extreme price event peaking at $19,728/MWh.
