How Queensland's grid-scale batteries performed in Q2 2026: energy and FCAS market revenue, $/MW, $/MWh, top performers, and price events.
Queensland (QLD1) batteries earned $23.26M in estimated gross energy and FCAS market revenue in Q2 2026, from 15 grid-scale units tracked by NEMPulse. Figures cover the full period.
Normalised across 2,914 MW and 7,000 MWh of registered capacity, the region earned $7,981/MW and $3,322/MWh for the period.
Total revenue was up 8% on Q1 2026, which returned $21.62M. Per MW per day — which strips out both fleet growth and the length of the window — earnings were down 22% at $88/MW/day. Optimal capture improved 3 points, from 53% to 57%.
Energy arbitrage supplied 88% of the total and FCAS 11%, with estimated Frequency Performance Payments adding $187k. Within FCAS, regulation accounted for 23% and contingency 77%; the single largest market was lower 6-second at $910k.
For context on the trading conditions, the average daily price spread (top two hours minus bottom two hours) in Queensland was $99/MWh, down 25% on the previous period, and the highest spot price reached $393/MWh.
Against the perfect-foresight energy benchmark, Queensland batteries captured 57% of what hindsight would have earned, an estimated $15.25M of unrealised upside.
On capture of the perfect-foresight energy benchmark, the strongest performers were Western Downs Battery Energy Storage System (70%), Brendale BESS (65%), Western Downs Battery Energy Storage System (BESS) (64%). At the other end: Wandoan Battery Energy Storage System (BESS) (47%), Chinchilla BESS, Units 1-80 (45%), Broadsound Energy Park (-44%) — capture reflects strategy, contracting and constraints as much as skill, so a low figure is not automatically underperformance.
The strongest single day was 23 Jun 2026 at $681k, and the best single battery-day was Supernode BESS on 3 Jun 2026 with $120k. Revenue stays concentrated: five of the period's 91 days delivered 13% of everything Queensland batteries earned.
2 batteries earned their first market revenue in the period — Woolooga BESS, Stanwell Battery Energy Storage System — adding 522 MW of earning capacity.
Western Downs Battery Energy Storage System (BESS) led the region with $3.21M. Full dispatch, state-of-charge and bidding detail is available on each battery's page.
