How New South Wales's grid-scale batteries performed in H2 2026: energy and FCAS market revenue, $/MW, $/MWh, top performers, and price events.
New South Wales (NSW1) batteries earned $11.81M in estimated gross energy and FCAS market revenue so far in H2 2026, from 15 grid-scale units tracked by NEMPulse. Figures cover H2 2026 to date (through 15 Aug 2026).
Normalised across 2,709 MW and 7,824 MWh of registered capacity, the region earned $4,358/MW and $1,509/MWh for the period.
Total revenue was down 21% on the same days of H1 2026, which returned $14.87M. Per MW per day — which strips out both fleet growth and the length of the window — earnings were down 61% at $95/MW/day. Optimal capture slipped 1 point, from 48% to 47%.
Energy arbitrage supplied 99% of the total and FCAS 0%, with estimated Frequency Performance Payments contributing the remaining 1% ($47k). Within FCAS, regulation accounted for 77% and contingency 23%; the single largest market was raise regulation at $20k.
For context on the trading conditions, the average daily price spread (top two hours minus bottom two hours) in New South Wales was $97/MWh, down 70% on the previous period, and the highest spot price reached $532/MWh.
Against the perfect-foresight energy benchmark, New South Wales batteries captured 47% of what hindsight would have earned, an estimated $12.43M of unrealised upside.
On capture of the perfect-foresight energy benchmark, the strongest performers were Limondale Battery (80%), New England BESS (68%), Eraring Battery Energy Storage System (65%). At the other end: Williamsdale BESS (-7%), Queanbeyan BESS (-19%), Liddell Battery Energy Storage System (-25%) — 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 $400k. Revenue stays concentrated: five of the period's 46 days delivered 32% of everything New South Wales batteries earned.
Eraring Battery Energy Storage System led the region with $4.06M. 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.
