Market analysis of 30 October 2025
Wind generators delivered 43.25 GWh on 30 October 2025 and solar generators delivered 52.27 GWh, a combined 95.51 GWh across Australia’s five eastern and southern market regions. In Network Map’s daily unit records for 1 October to 31 October 2025, that was the 26th-highest daily wind total of 31 dates and the 24th-highest combined wind and solar day.
Wind output averaged 80.66 GWh a day over the same dates, so 30 October ran 46.4% below the period mean. Hydro added 40.69 GWh, while black and brown coal units supplied 78.14 GWh.
The Daily Pattern Through The Month
The first chart places the event day in its monthly context. It shows daily wind and solar energy for each date from 1 October to 31 October. Solar was the larger of the two on 30 October, at 1.21 times the wind total.
Where The Energy Came From
Victoria supplied the largest regional share of wind and solar energy, 29.21 GWh or 30.6% of the day’s total. New South Wales followed with 27.43 GWh, and Queensland contributed 25.74 GWh.
Reading The Day For Asset Performance
A high-output day is a useful benchmark for comparing a single wind or solar unit with its fuel group and its region. The next step is to match each unit’s interval output with the prices that applied when the energy was delivered, which turns the volume result into a revenue view.
Figures use positive energy from Network Map’s daily unit records for 30 October 2025, grouped by source fuel classification and region. Daily totals are summed across all classified units.
