How New South Wales's grid-scale batteries performed in H2 2026: energy and FCAS market revenue, $/MW, $/MWh, top performers, and price events.
New South Wales (NSW1) batteries earned $45.78M in estimated gross energy and FCAS market revenue so far in H2 2026, from 17 grid-scale units tracked by NEMPulse. Figures cover H2 2026 to date (through 13 Nov 2026).
Normalised across 3,169 MW and 8,804 MWh of registered capacity, the region earned $14k/MW and $5,199/MWh for the period.
Total revenue was up 68% on the same days of H1 2026, which returned $27.25M. Per MW per day — which strips out both fleet growth and the length of the window — earnings were down 5% at $106/MW/day. Optimal capture slipped 7 points, from 48% to 40%.
Energy arbitrage supplied 99% of the total and FCAS 0%, with estimated Frequency Performance Payments contributing the remaining 1% ($202k). Within FCAS, regulation accounted for 86% and contingency 14%; the single largest market was raise regulation at $121k.
For context on the trading conditions, the average daily price spread (top two hours minus bottom two hours) in New South Wales was $160/MWh, down 5% on the previous period, and the highest spot price reached $23,200/MWh.
Against the perfect-foresight energy benchmark, New South Wales batteries captured 40% of what hindsight would have earned, an estimated $64.94M of unrealised upside.
On capture of the perfect-foresight energy benchmark, the strongest performers were Limondale Battery (68%), Orana BESS (65%), New England BESS (60%). At the other end: Liddell Battery Energy Storage System (22%), Queanbeyan BESS (20%), Eraring Battery Energy Storage System 2 (17%) — capture reflects strategy, contracting and constraints as much as skill, so a low figure is not automatically underperformance.
The strongest single day was 12 Oct 2026 at $5.87M, and the best single battery-day was New England BESS on 12 Oct 2026 with $975k. Revenue stays concentrated: five of the period's 136 days delivered 21% of everything New South Wales batteries earned.
One battery earned its first market revenue in the period — Williamsdale BESS — adding 250 MW of earning capacity.
Eraring Battery Energy Storage System led the region with $12.80M. Full dispatch, state-of-charge and bidding detail is available on each battery's page.
New South Wales saw 4 price events this period, the sharpest an extreme price event peaking at $23,200/MWh.
