How New South Wales's grid-scale batteries performed in Q3 2026: energy and FCAS market revenue, $/MW, $/MWh, top performers, and price events.
New South Wales (NSW1) batteries earned $27.97M in estimated gross energy and FCAS market revenue in Q3 2026, from 17 grid-scale units tracked by NEMPulse. Figures cover the full period.
Normalised across 3,169 MW and 8,804 MWh of registered capacity, the region earned $8,825/MW and $3,176/MWh for the period.
Total revenue was up 123% on Q2 2026, which returned $12.51M. Per MW per day — which strips out both fleet growth and the length of the window — earnings were up 55% at $96/MW/day. Optimal capture improved 15 points, from 39% to 54%.
Energy arbitrage supplied 99% of the total and FCAS 0%, with estimated Frequency Performance Payments contributing the remaining 1% ($114k). Within FCAS, regulation accounted for 82% and contingency 18%; the single largest market was raise regulation at $50k.
For context on the trading conditions, the average daily price spread (top two hours minus bottom two hours) in New South Wales was $101/MWh, up 12% on the previous period, and the highest spot price reached $532/MWh.
Against the perfect-foresight energy benchmark, New South Wales batteries captured 54% of what hindsight would have earned, an estimated $22.87M of unrealised upside.
On capture of the perfect-foresight energy benchmark, the strongest performers were Limondale Battery (81%), Orana BESS (72%), Eraring Battery Energy Storage System (68%). At the other end: Queanbeyan BESS (21%), Liddell Battery Energy Storage System (19%), Eraring Battery Energy Storage System 2 (-109%) — capture reflects strategy, contracting and constraints as much as skill, so a low figure is not automatically underperformance.
The strongest single day was 30 Jul 2026 at $1.24M, and the best single battery-day was Orana BESS on 30 Jul 2026 with $404k. Revenue stays concentrated: five of the period's 92 days delivered 16% of everything New South Wales batteries earned.
One battery earned its first market revenue in the period — Williamsdale BESS — adding 250 MW of earning capacity.
Eraring Battery Energy Storage System led the region with $8.80M. Full dispatch, state-of-charge and bidding detail is available on each battery's page.
New South Wales saw one price event this period, elevated prices peaking at $532/MWh.
