How New South Wales's grid-scale batteries performed in Q2 2026: energy and FCAS market revenue, $/MW, $/MWh, top performers, and price events.
New South Wales (NSW1) batteries earned $12.51M in estimated gross energy and FCAS market revenue in Q2 2026, from 13 grid-scale units tracked by NEMPulse. Figures cover the full period.
Normalised across 2,219 MW and 6,690 MWh of registered capacity, the region earned $5,640/MW and $1,871/MWh for the period.
Total revenue was down 33% on Q1 2026, which returned $18.81M. Per MW per day — which strips out both fleet growth and the length of the window — earnings were down 57% at $62/MW/day. Optimal capture slipped 6 points, from 45% to 39%.
Energy arbitrage supplied 98% of the total and FCAS 1%, with estimated Frequency Performance Payments contributing the remaining 1% ($100k). Within FCAS, regulation accounted for 91% and contingency 9%; the single largest market was raise regulation at $101k.
For context on the trading conditions, the average daily price spread (top two hours minus bottom two hours) in New South Wales was $90/MWh, down 56% on the previous period, and the highest spot price reached $341/MWh.
Against the perfect-foresight energy benchmark, New South Wales batteries captured 39% of what hindsight would have earned, an estimated $18.31M of unrealised upside.
On capture of the perfect-foresight energy benchmark, the strongest performers were Eraring Battery Energy Storage System (61%), Limondale Battery (61%), Riverena Energy Storage System 2 (58%). At the other end: Orana BESS (8%), New England BESS (5%), Liddell Battery Energy Storage System (-71%) — 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 $569k, and the best single battery-day was Eraring Battery Energy Storage System on 13 Apr 2026 with $245k. Revenue stays concentrated: five of the period's 91 days delivered 18% of everything New South Wales batteries earned.
Eraring Battery Energy Storage System led the region with $6.67M. Full dispatch, state-of-charge and bidding detail is available on each battery's page.
