Market analysis of 27 October 2023
Wind generators delivered 62.77 GWh on 27 October 2023 and solar generators delivered 52.94 GWh, a combined 115.71 GWh across Australia’s five eastern and southern market regions. In Network Map’s daily unit records for 1 October to 31 October 2023, that was the 21st-highest daily wind total of 31 dates and the 19th-highest combined wind and solar day.
Wind output averaged 77.43 GWh a day over the same dates, so 27 October ran 18.9% below the period mean. Hydro added 32.95 GWh, while black and brown coal units supplied 169.51 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 October to 31 October. Wind was the larger of the two on 27 October, at 1.19 times the solar total.
Where The Energy Came From
New South Wales supplied the largest regional share of wind and solar energy, 42.69 GWh or 37.1% of the day’s total. Queensland followed with 32.03 GWh, and Victoria contributed 23.38 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 27 October 2023, grouped by source fuel classification and region. Daily totals are summed across all classified units.
