How Victoria's grid-scale batteries performed in H2 2025: energy and FCAS market revenue, $/MW, $/MWh, top performers, and price events.
Victoria (VIC1) batteries earned $40.95M in estimated gross energy and FCAS market revenue in H2 2025, from 12 grid-scale units tracked by NEMPulse. Figures cover the full period.
Normalised across 1,620 MW and 3,296 MWh of registered capacity, the region earned $25k/MW and $12k/MWh for the period.
Energy arbitrage supplied 93% of the total and FCAS 6%, with estimated Frequency Performance Payments adding $531k. Within FCAS, regulation accounted for 69% and contingency 31%; the single largest market was raise regulation at $1.17M.
For context on the trading conditions, the average daily price spread (top two hours minus bottom two hours) in Victoria was $180/MWh, and the highest spot price reached $980/MWh.
Against the perfect-foresight energy benchmark, Victoria batteries captured 59% of what hindsight would have earned, an estimated $24.23M of unrealised upside.
On capture of the perfect-foresight energy benchmark, the strongest performers were Koorangie Energy Storage System (76%), Melbourne Renewable Energy Hub Connection A3 (76%), Rangebank BESS (68%). At the other end: Victorian Big Battery (39%), Gannawarra Energy Storage System (31%), Bulgana Green Power Hub (23%) — capture reflects strategy, contracting and constraints as much as skill, so a low figure is not automatically underperformance.
The strongest single day was 1 Sep 2025 at $877k, and the best single battery-day was Koorangie Energy Storage System on 1 Sep 2025 with $257k. Revenue stays concentrated: five of the period's 184 days delivered 8% of everything Victoria batteries earned.
3 batteries earned their first market revenue in the period — Melbourne Renewable Energy Hub Connection A1, Melbourne Renewable Energy Hub Connection A3, Melbourne Renewable Energy Hub Connection A2 — adding 600 MW of earning capacity.
Rangebank BESS led the region with $9.09M. Full dispatch, state-of-charge and bidding detail is available on each battery's page.
Victoria saw 16 price events this period, the sharpest elevated prices peaking at $980/MWh.
