How Queensland's grid-scale batteries performed in Q4 2026: energy and FCAS market revenue, $/MW, $/MWh, top performers, and price events.
Queensland (QLD1) batteries earned $546k in estimated gross energy and FCAS market revenue so far in Q4 2026, from 14 grid-scale units tracked by NEMPulse. Figures cover Q4 2026 to date (through 1 Oct 2026).
Normalised across 2,792 MW and 6,156 MWh of registered capacity, the region earned $195/MW and $89/MWh for the period.
Total revenue was up 1562% on the same days of Q3 2026, which returned $33k. Per MW per day — which strips out both fleet growth and the length of the window — earnings were up 921% at $195/MW/day. Optimal capture improved 54 points, from 14% to 68%.
Energy arbitrage supplied 99% of the total and FCAS 1%, with estimated Frequency Performance Payments contributing the remaining 0% ($258). Within FCAS, regulation accounted for 94% and contingency 6%; the single largest market was raise regulation at $4k.
Against the perfect-foresight energy benchmark, Queensland batteries captured 68% of what hindsight would have earned, an estimated $243k of unrealised upside.
On capture of the perfect-foresight energy benchmark, the strongest performers were Western Downs Battery Energy Storage System (90%), Swanbank BESS (78%), Brendale BESS (77%). At the other end: Greenbank BESS (59%), Chinchilla BESS, Units 1-80 (46%), Tarong BESS (40%) — capture reflects strategy, contracting and constraints as much as skill, so a low figure is not automatically underperformance.
The strongest single day was 1 Oct 2026 at $546k, and the best single battery-day was Supernode BESS on 1 Oct 2026 with $94k.
Supernode BESS led the region with $94k. Full dispatch, state-of-charge and bidding detail is available on each battery's page.
