How New South Wales's grid-scale batteries performed in 2026: energy and FCAS market revenue, $/MW, $/MWh, top performers, and price events.
New South Wales (NSW1) batteries earned $38.83M in estimated gross energy and FCAS market revenue so far in 2026, from 15 grid-scale units tracked by NEMPulse. Figures cover 2026 to date (through 31 Jul 2026).
Normalised across 2,419 MW and 7,194 MWh of registered capacity, the region earned $16k/MW and $5,397/MWh for the period.
Energy arbitrage supplied 98% of the total and FCAS 1%, with estimated Frequency Performance Payments adding $212k. Within FCAS, regulation accounted for 85% and contingency 15%; the single largest market was raise regulation at $233k.
For context on the trading conditions, the average daily price spread (top two hours minus bottom two hours) in New South Wales was $139/MWh, and the highest spot price reached $20,300/MWh.
Against the perfect-foresight energy benchmark, New South Wales batteries captured 43% of what hindsight would have earned, an estimated $49.80M of unrealised upside.
On capture of the perfect-foresight energy benchmark, the strongest performers were New England BESS (67%), Limondale Battery (63%), Eraring Battery Energy Storage System (60%). At the other end: Williamsdale BESS (-7%), Mortlake Battery Energy Storage System (-47%), Liddell Battery Energy Storage System (-50%) — 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 212 days delivered 31% of everything New South Wales batteries earned.
4 batteries earned their first market revenue in the period — Orana BESS, New England BESS, New England BESS, Quorn Park Solar Hybrid — adding 634 MW of earning capacity.
Eraring Battery Energy Storage System led the region with $22.28M. Full dispatch, state-of-charge and bidding detail is available on each battery's page.
New South Wales saw 14 price events this period, the sharpest an extreme price event peaking at $20,300/MWh.
