Market analysis of 28 October 2022
Wind generators delivered 109.99 GWh on 28 October 2022 and solar generators delivered 36.38 GWh, a combined 146.38 GWh across Australia’s five eastern and southern market regions. In Network Map’s daily unit records for 20 October to 31 October 2022, that was the highest daily wind total of 12 dates and the highest combined wind and solar day.
Wind output averaged 70.84 GWh a day over the same dates, so 28 October ran 55.3% above the period mean. Hydro added 37.55 GWh, while black and brown coal units supplied 138.02 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 20 October to 31 October. Wind was the larger of the two on 28 October, at 3.02 times the solar total.
Where The Energy Came From
Victoria supplied the largest regional share of wind and solar energy, 58.16 GWh or 39.7% of the day’s total. New South Wales followed with 43.04 GWh, and South Australia contributed 21.35 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 28 October 2022, grouped by source fuel classification and region. Daily totals are summed across all classified units.
