Market analysis of 19 April 2025
Wind generators delivered 71.73 GWh on 19 April 2025 and solar generators delivered 36.09 GWh, a combined 107.82 GWh across Australia’s five eastern and southern market regions. In Network Map’s daily unit records for 1 April to 30 April 2025, that was the 7th-highest daily wind total of 30 dates and the 9th-highest combined wind and solar day.
Wind output averaged 56.83 GWh a day over the same dates, so 19 April ran 26.2% above the period mean. Hydro added 24.99 GWh, while black and brown coal units supplied 106.83 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 April to 30 April. Wind was the larger of the two on 19 April, at 1.99 times the solar total.

Where The Energy Came From
Victoria supplied the largest regional share of wind and solar energy, 32.91 GWh or 30.5% of the day’s total. South Australia followed with 30.00 GWh, and New South Wales contributed 21.32 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.
