How Queensland's grid-scale batteries performed in 2025: energy and FCAS market revenue, $/MW, $/MWh, top performers, and price events.
Queensland (QLD1) batteries earned $67.63M in estimated gross energy and FCAS market revenue in 2025, from 11 grid-scale units tracked by NEMPulse. NEMPulse data begins 13 Apr 2025, so figures cover 13 Apr 2025–31 Dec 2025 of this period.
Normalised across 1,882 MW and 3,617 MWh of registered capacity, the region earned $36k/MW and $19k/MWh for the period.
Energy arbitrage supplied 77% of the total and FCAS 22%, with estimated Frequency Performance Payments adding $447k. Within FCAS, regulation accounted for 14% and contingency 86%; the single largest market was lower 6-second at $7.51M.
For context on the trading conditions, the average daily price spread (top two hours minus bottom two hours) in Queensland was $256/MWh, and the highest spot price reached $16,568/MWh.
Against the perfect-foresight energy benchmark, Queensland batteries captured 65% of what hindsight would have earned, an estimated $28.21M of unrealised upside.
On capture of the perfect-foresight energy benchmark, the strongest performers were Western Downs Battery Energy Storage System (70%), Greenbank BESS (68%), Chinchilla BESS, Units 1-80 (65%). At the other end: Bouldercombe Battery Project (46%), 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 12 Jun 2025 at $8.01M, and the best single battery-day was Western Downs Battery Energy Storage System on 12 Jun 2025 with $4.49M. Revenue stays concentrated: five of the period's 263 days delivered 22% of everything Queensland batteries earned.
Western Downs Battery Energy Storage System led the region with $26.07M. Full dispatch, state-of-charge and bidding detail is available on each battery's page.
Queensland saw 37 price events this period, the sharpest an extreme price event peaking at $16,568/MWh.

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.
