How New South Wales's grid-scale batteries performed in H1 2026: energy and FCAS market revenue, $/MW, $/MWh, top performers, and price events.
New South Wales (NSW1) batteries earned $31.24M in estimated gross energy and FCAS market revenue in H1 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 $13k/MW and $4,342/MWh for the period.
Total revenue was up 76% on H2 2025, which returned $17.79M. Per MW per day — which strips out both fleet growth and the length of the window — earnings were down 28% at $71/MW/day. Optimal capture improved 11 points, from 31% to 42%.
Energy arbitrage supplied 98% of the total and FCAS 1%, with estimated Frequency Performance Payments adding $185k. Within FCAS, regulation accounted for 86% and contingency 14%; the single largest market was raise regulation at $222k.
For context on the trading conditions, the average daily price spread (top two hours minus bottom two hours) in New South Wales was $148/MWh, down 44% on the previous period, and the highest spot price reached $20,300/MWh.
Against the perfect-foresight energy benchmark, New South Wales batteries captured 42% of what hindsight would have earned, an estimated $41.80M of unrealised upside.
On capture of the perfect-foresight energy benchmark, the strongest performers were Eraring Battery Energy Storage System (59%), Limondale Battery (57%), Riverena Energy Storage System 2 (56%). At the other end: Orana BESS (8%), Liddell Battery Energy Storage System (-55%), Mortlake Battery Energy Storage System (-58%) — capture reflects strategy, contracting and constraints as much as skill, so a low figure is not automatically underperformance.
The strongest single day was 10 Jan 2026 at $6.64M, and the best single battery-day was Eraring Battery Energy Storage System on 10 Jan 2026 with $3.62M. Revenue stays concentrated: five of the period's 181 days delivered 36% of everything New South Wales batteries earned.
4 batteries earned their first market revenue in the period — Orana BESS, Quorn Park Solar Hybrid, New England BESS, New England BESS — adding 634 MW of earning capacity.
Eraring Battery Energy Storage System led the region with $19.56M. Full dispatch, state-of-charge and bidding detail is available on each battery's page.
New South Wales saw 13 price events this period, the sharpest an extreme price event peaking at $20,300/MWh.
