How Victoria's grid-scale batteries performed in October 2026: energy and FCAS market revenue, $/MW, $/MWh, top performers, and price events.
Victoria (VIC1) batteries earned $100k in estimated gross energy and FCAS market revenue so far in October 2026, from 9 grid-scale units tracked by NEMPulse. Figures cover October 2026 to date (through 1 Oct 2026).
Normalised across 1,555 MW and 3,260 MWh of registered capacity, the region earned $64/MW and $31/MWh for the period.
Total revenue was up 18% on the same days of September 2026, which returned $85k. Per MW per day — which strips out both fleet growth and the length of the window — earnings were up 90% at $64/MW/day. Optimal capture slipped 12 points, from 29% to 17%.
Energy arbitrage supplied 94% of the total and FCAS 5%, with estimated Frequency Performance Payments contributing the remaining 1% ($204). Within FCAS, regulation accounted for 89% and contingency 11%; the single largest market was raise regulation at $4k.
Against the perfect-foresight energy benchmark, Victoria batteries captured 17% of what hindsight would have earned, an estimated $457k of unrealised upside.
On capture of the perfect-foresight energy benchmark, the strongest performers were Mornington BESS (100%), Rangebank BESS (44%), Koorangie Energy Storage System (40%). At the other end: Victorian Big Battery (-3%), Melbourne Renewable Energy Hub Connection A3 (-15%), Hazelwood Battery Energy Storage System (-63%) — capture reflects strategy, contracting and constraints as much as skill, so a low figure is not automatically underperformance.
The strongest single day was 1 Oct 2026 at $100k, and the best single battery-day was Mornington BESS on 1 Oct 2026 with $36k.
Mornington BESS led the region with $36k. Full dispatch, state-of-charge and bidding detail is available on each battery's page.
