Market analysis of 6 December 2025
Wind generators delivered 100.97 GWh on 6 December 2025 and solar generators delivered 37.57 GWh, a combined 138.54 GWh across Australia’s five eastern and southern market regions. In Network Map’s daily unit records for 1 December to 31 December 2025, that was the 2nd-highest daily wind total of 31 dates and the 4th-highest combined wind and solar day.
Wind output averaged 66.07 GWh a day over the same dates, so 6 December ran 52.8% above the period mean. Hydro added 26.66 GWh, while black and brown coal units supplied 104.74 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 December to 31 December. Wind was the larger of the two on 6 December, at 2.69 times the solar total.

Where The Energy Came From
New South Wales supplied the largest regional share of wind and solar energy, 46.71 GWh or 33.7% of the day’s total. Victoria followed with 30.62 GWh, and Queensland contributed 27.35 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 6 December 2025, grouped by source fuel classification and region. Daily totals are summed across all classified units.
