How Queensland's grid-scale batteries performed in June 2026: energy and FCAS market revenue, $/MW, $/MWh, top performers, and price events.
Queensland (QLD1) batteries earned $7.70M in estimated gross energy and FCAS market revenue in June 2026, from 14 grid-scale units tracked by NEMPulse. Figures cover the full period.
Normalised across 2,912 MW and 6,996 MWh of registered capacity, the region earned $2,643/MW and $1,100/MWh for the period.
Total revenue was up 14% on May 2026, which returned $6.73M. Per MW per day — which strips out both fleet growth and the length of the window — earnings were up 6% at $88/MW/day. Optimal capture improved 5 points, from 49% to 54%.
Energy arbitrage supplied 90% of the total and FCAS 9%, with estimated Frequency Performance Payments adding $52k. Within FCAS, regulation accounted for 26% and contingency 74%; the single largest market was lower 6-second at $230k.
For context on the trading conditions, the average daily price spread (top two hours minus bottom two hours) in Queensland was $91/MWh, down 11% on the previous period, and the highest spot price reached $233/MWh.
Against the perfect-foresight energy benchmark, Queensland batteries captured 54% of what hindsight would have earned, an estimated $5.90M of unrealised upside.
On capture of the perfect-foresight energy benchmark, the strongest performers were Swanbank BESS (68%), Western Downs Battery Energy Storage System (BESS) (64%), Western Downs Battery Energy Storage System (63%). At the other end: Bouldercombe Battery Project (42%), Greenbank BESS (38%), Broadsound Energy Park (-37%) — capture reflects strategy, contracting and constraints as much as skill, so a low figure is not automatically underperformance.
The strongest single day was 23 Jun 2026 at $681k, and the best single battery-day was Supernode BESS on 3 Jun 2026 with $120k. Revenue stays concentrated: five of the period's 30 days delivered 38% of everything Queensland batteries earned.
One battery earned its first market revenue in the period — Stanwell Battery Energy Storage System — adding 300 MW of earning capacity.
Supernode BESS led the region with $1.22M. Full dispatch, state-of-charge and bidding detail is available on each battery's page.
