How New South Wales's grid-scale batteries performed in October 2026: energy and FCAS market revenue, $/MW, $/MWh, top performers, and price events.
New South Wales (NSW1) batteries earned $1.05M in estimated gross energy and FCAS market revenue so far in October 2026, from 16 grid-scale units tracked by NEMPulse. Figures cover October 2026 to date (through 7 Oct 2026).
Normalised across 3,159 MW and 8,784 MWh of registered capacity, the region earned $331/MW and $119/MWh for the period.
Total revenue was down 68% on the same days of September 2026, which returned $3.28M. Per MW per day — which strips out both fleet growth and the length of the window — earnings were down 69% at $47/MW/day. Optimal capture slipped 42 points, from 68% to 27%.
Energy arbitrage supplied 96% of the total and FCAS 2%, with estimated Frequency Performance Payments contributing the remaining 2% ($15k). Within FCAS, regulation accounted for 91% and contingency 9%; the single largest market was raise regulation at $13k.
For context on the trading conditions, the average daily price spread (top two hours minus bottom two hours) in New South Wales was $75/MWh, down 40% on the previous period, and the highest spot price reached $146/MWh.
Against the perfect-foresight energy benchmark, New South Wales batteries captured 27% of what hindsight would have earned, an estimated $2.71M of unrealised upside.
On capture of the perfect-foresight energy benchmark, the strongest performers were Limondale Battery (59%), New England BESS (47%), Darlington Point Energy Storage System (43%). At the other end: Orana BESS (25%), Wallgrove BESS 1 (18%), Waratah Super Battery (5%) — capture reflects strategy, contracting and constraints as much as skill, so a low figure is not automatically underperformance.
The strongest single day was 4 Oct 2026 at $335k, and the best single battery-day was Eraring Battery Energy Storage System on 4 Oct 2026 with $122k.
Eraring Battery Energy Storage System led the region with $348k. Full dispatch, state-of-charge and bidding detail is available on each battery's page.
