Market analysis of 22 June 2023
Wind generators delivered 81.45 GWh on 22 June 2023 and solar generators delivered 14.45 GWh, a combined 95.89 GWh across Australia’s five eastern and southern market regions. In Network Map’s daily unit records for 1 June to 30 June 2023, that was the 21st-highest daily wind total of 30 dates and the 22nd-highest combined wind and solar day.
Wind output averaged 93.09 GWh a day over the same dates, so 22 June ran 12.5% below the period mean. Hydro added 68.09 GWh, while black and brown coal units supplied 208.13 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 22 June, at 5.64 times the solar total.
Where The Energy Came From
Victoria supplied the largest regional share of wind and solar energy, 34.38 GWh or 35.9% of the day’s total. South Australia followed with 31.24 GWh, and Queensland contributed 18.33 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 22 June 2023, grouped by source fuel classification and region. Daily totals are summed across all classified units.
