The Day In Its Monthly Context
The first chart places 25 December alongside the other dates of December 2025, splitting each day into net energy value and ancillary-service value. It shows whether the day stood out because of energy prices or because of ancillary services.
How The Regions Compared
Batteries in Victoria recorded the largest regional total, AUD 297,438 from 12 units. Queensland recorded AUD 233,262 from 11 units; South Australia recorded AUD 214,156 from 15 units; New South Wales recorded AUD 142,597 from 13 units.
Charging value was positive in Victoria, Queensland, South Australia and New South Wales, which happens when batteries charge while prices are below zero.
Using The Day For Battery Benchmarking
A high-value day is a useful benchmark: first find when value was concentrated, then separate the energy and ancillary-service products behind it. Comparing a single battery with its regional cohort on the same day shows how its dispatch captured the price spread.
Figures are modelled wholesale value from Network Map’s battery daily totals for 25 December 2025: discharge value plus signed charging value plus ancillary-service value, for intervals ending 00:05 to 24:00 UTC+10.
