How Queensland's grid-scale batteries performed in H2 2025: energy and FCAS market revenue, $/MW, $/MWh, top performers, and price events.
Queensland (QLD1) batteries earned $43.53M in estimated gross energy and FCAS market revenue in H2 2025, from 11 grid-scale units tracked by NEMPulse. Figures cover the full period.
Normalised across 1,882 MW and 3,617 MWh of registered capacity, the region earned $23k/MW and $12k/MWh for the period.
Energy arbitrage supplied 76% of the total and FCAS 23%, with estimated Frequency Performance Payments adding $435k. Within FCAS, regulation accounted for 14% and contingency 86%; the single largest market was lower 6-second at $4.82M.
For context on the trading conditions, the average daily price spread (top two hours minus bottom two hours) in Queensland was $183/MWh, and the highest spot price reached $1,000/MWh.
Against the perfect-foresight energy benchmark, Queensland batteries captured 63% of what hindsight would have earned, an estimated $18.72M of unrealised upside.
On capture of the perfect-foresight energy benchmark, the strongest performers were Greenbank BESS (71%), Western Downs Battery Energy Storage System (69%), Chinchilla BESS, Units 1-80 (64%). At the other end: Bouldercombe Battery Project (36%), Supernode BESS (36%), Swanbank BESS (-1%) — capture reflects strategy, contracting and constraints as much as skill, so a low figure is not automatically underperformance.
The strongest single day was 29 Oct 2025 at $831k, and the best single battery-day was Western Downs Battery Energy Storage System on 29 Oct 2025 with $307k. Revenue stays concentrated: five of the period's 184 days delivered 8% of everything Queensland batteries earned.
4 batteries earned their first market revenue in the period — Western Downs Battery Energy Storage System (BESS), Brendale BESS, Tarong BESS, Supernode BESS — adding 1,020 MW of earning capacity.
Western Downs Battery Energy Storage System led the region with $13.59M. Full dispatch, state-of-charge and bidding detail is available on each battery's page.
Queensland saw 16 price events this period, the sharpest a price spike peaking at $1,000/MWh.
