How New South Wales's grid-scale batteries performed in July 2026: energy and FCAS market revenue, $/MW, $/MWh, top performers, and price events.
New South Wales (NSW1) batteries earned $7.61M in estimated gross energy and FCAS market revenue in July 2026, from 14 grid-scale units tracked by NEMPulse. Figures cover the full period.
Normalised across 2,409 MW and 7,174 MWh of registered capacity, the region earned $3,159/MW and $1,061/MWh for the period.
Total revenue was up 184% on June 2026, which returned $2.68M. Per MW per day — which strips out both fleet growth and the length of the window — earnings were up 176% at $102/MW/day. Optimal capture improved 24 points, from 23% to 48%.
Energy arbitrage supplied 99% of the total and FCAS 0%, with estimated Frequency Performance Payments contributing the remaining 1% ($29k). Within FCAS, regulation accounted for 76% and contingency 24%; the single largest market was raise regulation at $11k.
For context on the trading conditions, the average daily price spread (top two hours minus bottom two hours) in New South Wales was $95/MWh, up 22% on the previous period, and the highest spot price reached $532/MWh.
Against the perfect-foresight energy benchmark, New South Wales batteries captured 48% of what hindsight would have earned, an estimated $8.00M of unrealised upside.
On capture of the perfect-foresight energy benchmark, the strongest performers were New England BESS (77%), Limondale Battery (77%), Eraring Battery Energy Storage System (66%). At the other end: Williamsdale BESS (-6%), Queanbeyan BESS (-16%), Liddell Battery Energy Storage System (-47%) — 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 31 days delivered 43% of everything New South Wales batteries earned.
Eraring Battery Energy Storage System led the region with $2.72M. 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.
