Market analysis of 8 July 2023
Wind generators delivered 158.25 GWh on 8 July 2023 and solar generators delivered 25.65 GWh, a combined 183.91 GWh across Australia’s five eastern and southern market regions. In Network Map’s daily unit records for 1 July to 31 July 2023, that was the highest daily wind total of 31 dates and the highest combined wind and solar day.
Wind output averaged 84.60 GWh a day over the same dates, so 8 July ran 87.0% above the period mean. Hydro added 28.44 GWh, while black and brown coal units supplied 158.04 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 8 July, at 6.17 times the solar total.
Where The Energy Came From
Victoria supplied the largest regional share of wind and solar energy, 71.09 GWh or 38.7% of the day’s total. New South Wales followed with 42.57 GWh, and South Australia contributed 34.50 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 8 July 2023, grouped by source fuel classification and region. Daily totals are summed across all classified units.
