Market analysis of 25 July 2025
Wind generators delivered 123.46 GWh on 25 July 2025 and solar generators delivered 22.82 GWh, a combined 146.28 GWh across Australia’s five eastern and southern market regions. In Network Map’s daily unit records for 1 July to 31 July 2025, that was the 8th-highest daily wind total of 31 dates and the 8th-highest combined wind and solar day.
Wind output averaged 90.70 GWh a day over the same dates, so 25 July ran 36.1% above the period mean. Hydro added 27.80 GWh, while black and brown coal units supplied 102.37 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 July to 31 July. Wind was the larger of the two on 25 July, at 5.41 times the solar total.
Where The Energy Came From
Victoria supplied the largest regional share of wind and solar energy, 55.95 GWh or 38.2% of the day’s total. South Australia followed with 36.20 GWh, and Queensland contributed 29.46 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 25 July 2025, grouped by source fuel classification and region. Daily totals are summed across all classified units.
