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 $2.81M in estimated gross energy and FCAS market revenue so far in Q4 2026, from 15 grid-scale units tracked by NEMPulse. Figures cover Q4 2026 to date (through 7 Oct 2026).
Normalised across 2,794 MW and 6,160 MWh of registered capacity, the region earned $1,007/MW and $457/MWh for the period.
Total revenue was up 52% on the same days of Q3 2026, which returned $1.85M. Per MW per day — which strips out both fleet growth and the length of the window — earnings were up 47% at $144/MW/day. Optimal capture improved 1 point, from 66% to 68%.
Energy arbitrage supplied 98% of the total and FCAS 2%, with estimated Frequency Performance Payments contributing the remaining 0% ($18k). Within FCAS, regulation accounted for 95% and contingency 5%; the single largest market was raise regulation at $31k.
For context on the trading conditions, the average daily price spread (top two hours minus bottom two hours) in Queensland was $106/MWh, up 34% on the previous period, and the highest spot price reached $121/MWh.
Against the perfect-foresight energy benchmark, Queensland batteries captured 68% of what hindsight would have earned, an estimated $1.30M of unrealised upside.
On capture of the perfect-foresight energy benchmark, the strongest performers were Swanbank BESS (82%), Supernode BESS (78%), Western Downs Battery Energy Storage System (74%). At the other end: Chinchilla BESS, Units 1-80 (58%), Bouldercombe Battery Project (57%), Tarong BESS (42%) — 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 $548k, and the best single battery-day was Supernode BESS on 4 Oct 2026 with $107k.
Supernode BESS led the region with $537k. Full dispatch, state-of-charge and bidding detail is available on each battery's page.

Automatically generated from AEMO public data using fixed templates (not AI-written). Figures are estimated gross market revenue (energy + FCAS) from dispatch — they exclude contracts, hedges and network-support schemes (e.g. SIPS), so actual commercial revenue will differ.
