How Queensland's grid-scale batteries performed in 2026: energy and FCAS market revenue, $/MW, $/MWh, top performers, and price events.
Queensland (QLD1) batteries earned $70.58M in estimated gross energy and FCAS market revenue so far in 2026, from 15 grid-scale units tracked by NEMPulse. Figures cover 2026 to date (through 11 Sep 2026).
Normalised across 2,794 MW and 6,160 MWh of registered capacity, the region earned $25k/MW and $11k/MWh for the period.
Energy arbitrage supplied 92% of the total and FCAS 7%, with estimated Frequency Performance Payments contributing the remaining 1% ($546k). Within FCAS, regulation accounted for 33% and contingency 67%; the single largest market was lower 6-second at $1.45M.
For context on the trading conditions, the average daily price spread (top two hours minus bottom two hours) in Queensland was $112/MWh, 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 $43.40M of unrealised upside.
On capture of the perfect-foresight energy benchmark, the strongest performers were Supernode BESS (68%), Swanbank BESS (67%), Woolooga BESS (65%). At the other end: Bouldercombe Battery Project (44%), Broadsound Energy Park (39%), Stanwell Battery Energy Storage System (-114%) — 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 $2.06M, and the best single battery-day was Supernode BESS on 15 Jan 2026 with $602k. Revenue stays concentrated: five of the period's 254 days delivered 7% of everything Queensland batteries earned.
3 batteries earned their first market revenue in the period — Supernode BESS, Broadsound Energy Park, Woolooga BESS — adding 662 MW of earning capacity.
Tarong BESS led the region with $9.37M. 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.
