How New South Wales's grid-scale batteries performed in June 2026: energy and FCAS market revenue, $/MW, $/MWh, top performers, and price events.
New South Wales (NSW1) batteries earned $2.59M in estimated gross energy and FCAS market revenue in June 2026, from 15 grid-scale units tracked by NEMPulse. Figures cover the full period.
Normalised across 2,419 MW and 7,194 MWh of registered capacity, the region earned $1,069/MW and $359/MWh for the period.
Total revenue was down 33% on May 2026, which returned $3.84M. Per MW per day — which strips out both fleet growth and the length of the window — earnings were down 48% at $36/MW/day. Optimal capture slipped 13 points, from 36% to 23%.
Energy arbitrage supplied 98% of the total and FCAS 1%, with estimated Frequency Performance Payments adding $23k. Within FCAS, regulation accounted for 84% and contingency 16%; the single largest market was raise regulation at $21k.
For context on the trading conditions, the average daily price spread (top two hours minus bottom two hours) in New South Wales was $78/MWh, down 15% on the previous period, and the highest spot price reached $300/MWh.
Against the perfect-foresight energy benchmark, New South Wales batteries captured 23% of what hindsight would have earned, an estimated $8.16M of unrealised upside.
On capture of the perfect-foresight energy benchmark, the strongest performers were Limondale Battery (61%), Riverena Energy Storage System 2 (53%), Darlington Point Energy Storage System (50%). At the other end: Waratah Super Battery (6%), Liddell Battery Energy Storage System (-72%), Mortlake Battery Energy Storage System (-100%) — capture reflects strategy, contracting and constraints as much as skill, so a low figure is not automatically underperformance.
The strongest single day was 26 Jun 2026 at $590k, and the best single battery-day was Eraring Battery Energy Storage System on 26 Jun 2026 with $242k. Revenue stays concentrated: five of the period's 30 days delivered 75% of everything New South Wales batteries earned.
Eraring Battery Energy Storage System led the region with $1.41M. Full dispatch, state-of-charge and bidding detail is available on each battery's page.
