Market analysis of 30 May 2025
Wind generators delivered 44.68 GWh on 30 May 2025 and solar generators delivered 25.33 GWh, a combined 70.01 GWh across Australia’s five eastern and southern market regions. In Network Map’s daily unit records for 1 May to 31 May 2025, that was the 23rd-highest daily wind total of 31 dates and the 24th-highest combined wind and solar day.
Wind output averaged 69.05 GWh a day over the same dates, so 30 May ran 35.3% below the period mean. Hydro added 46.38 GWh, while black and brown coal units supplied 127.15 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 May to 31 May. Wind was the larger of the two on 30 May, at 1.76 times the solar total.
Where The Energy Came From
South Australia supplied the largest regional share of wind and solar energy, 20.58 GWh or 29.4% of the day’s total. New South Wales followed with 19.16 GWh, and Victoria contributed 17.91 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 May 2025, grouped by source fuel classification and region. Daily totals are summed across all classified units.
