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 $142k in estimated gross energy and FCAS market revenue so far in October 2026, from 12 grid-scale units tracked by NEMPulse. Figures cover October 2026 to date (through 1 Oct 2026).
Normalised across 2,084 MW and 5,521 MWh of registered capacity, the region earned $68/MW and $26/MWh for the period.
Total revenue was down 39% on the same days of September 2026, which returned $233k. Per MW per day — which strips out both fleet growth and the length of the window — earnings were down 49% at $68/MW/day. Optimal capture slipped 56 points, from 76% to 20%.
Energy arbitrage supplied 97% of the total and FCAS 3%, with estimated Frequency Performance Payments contributing the remaining 0% ($271). Within FCAS, regulation accounted for 96% and contingency 4%; the single largest market was raise regulation at $2k.
Against the perfect-foresight energy benchmark, New South Wales batteries captured 20% of what hindsight would have earned, an estimated $526k of unrealised upside.
On capture of the perfect-foresight energy benchmark, the strongest performers were Limondale Battery (70%), Orana BESS (59%), Capital Battery (42%). At the other end: Liddell Battery Energy Storage System (-3%), Eraring Battery Energy Storage System (-7%), Smithfield Battery Energy Storage System, Units 1 - 36 (-29%) — capture reflects strategy, contracting and constraints as much as skill, so a low figure is not automatically underperformance.
The strongest single day was 1 Oct 2026 at $142k, and the best single battery-day was Orana BESS on 1 Oct 2026 with $100k.
Orana BESS led the region with $100k. Full dispatch, state-of-charge and bidding detail is available on each battery's page.
