Market analysis of 23 June 2025
Wind generators delivered 152.81 GWh on 23 June 2025 and solar generators delivered 27.79 GWh, a combined 180.60 GWh across Australia’s five eastern and southern market regions. In Network Map’s daily unit records for 1 June to 30 June 2025, that was the 2nd-highest daily wind total of 30 dates and the 2nd-highest combined wind and solar day.
Wind output averaged 76.41 GWh a day over the same dates, so 23 June ran 100.0% above the period mean. Hydro added 19.69 GWh, while black and brown coal units supplied 107.28 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 June to 30 June. Wind was the larger of the two on 23 June, at 5.50 times the solar total.
Where The Energy Came From
Victoria supplied the largest regional share of wind and solar energy, 69.85 GWh or 38.7% of the day’s total. New South Wales followed with 40.37 GWh, and South Australia contributed 32.04 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 23 June 2025, grouped by source fuel classification and region. Daily totals are summed across all classified units.
