How Queensland's grid-scale batteries performed in August 2026: energy and FCAS market revenue, $/MW, $/MWh, top performers, and price events.
Queensland (QLD1) batteries earned $229k in estimated gross energy and FCAS market revenue so far in August 2026, from 13 grid-scale units tracked by NEMPulse. Figures cover August 2026 to date (through 1 Aug 2026).
Normalised across 2,392 MW and 5,207 MWh of registered capacity, the region earned $96/MW and $44/MWh for the period.
Total revenue was up 597% on the same days of July 2026, which returned $33k. Per MW per day — which strips out both fleet growth and the length of the window — earnings were up 400% at $96/MW/day. Optimal capture improved 40 points, from 14% to 54%.
Energy arbitrage supplied 97% of the total and FCAS 2%, with estimated Frequency Performance Payments adding $301. Within FCAS, regulation accounted for 91% and contingency 9%; the single largest market was raise regulation at $4k.
For context on the trading conditions, the average daily price spread (top two hours minus bottom two hours) in Queensland was $82/MWh, up 68% on the previous period, and the highest spot price reached $90/MWh.
Against the perfect-foresight energy benchmark, Queensland batteries captured 54% of what hindsight would have earned, an estimated $188k of unrealised upside.
On capture of the perfect-foresight energy benchmark, the strongest performers were Brendale BESS (73%), Supernode BESS (72%), Western Downs Battery Energy Storage System (71%). At the other end: Western Downs Battery Energy Storage System (BESS) (22%), Wandoan Battery Energy Storage System (BESS) (16%), Broadsound Energy Park (-8%) — capture reflects strategy, contracting and constraints as much as skill, so a low figure is not automatically underperformance.
The strongest single day was 1 Aug 2026 at $229k, and the best single battery-day was Supernode BESS on 1 Aug 2026 with $40k.
Supernode BESS led the region with $40k. Full dispatch, state-of-charge and bidding detail is available on each battery's page.
