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 $12.52M in estimated gross energy and FCAS market revenue in Q2 2026, from 14 grid-scale units tracked by NEMPulse. Figures cover the full period.
Normalised across 2,319 MW and 6,942 MWh of registered capacity, the region earned $5,398/MW and $1,803/MWh for the period.
Total revenue was down 33% on Q1 2026, which returned $18.72M. Per MW per day — which strips out both fleet growth and the length of the window — earnings were down 56% at $59/MW/day. Optimal capture slipped 7 points, from 45% to 38%.
Energy arbitrage supplied 98% of the total and FCAS 1%, with estimated Frequency Performance Payments adding $92k. 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 38% of what hindsight would have earned, an estimated $19.53M of unrealised upside.
On capture of the perfect-foresight energy benchmark, the strongest performers were Riverena Energy Storage System 2 (59%), Darlington Point Energy Storage System (59%), Eraring Battery Energy Storage System (59%). At the other end: Orana BESS (8%), Mortlake Battery Energy Storage System (-57%), Liddell Battery Energy Storage System (-75%) — 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 13 Apr 2026 with $244k. 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 $6.65M. Full dispatch, state-of-charge and bidding detail is available on each battery's page.
