Wind power blows away monthly generation records, nationally and in four states

A windy July has blown away a number of wind energy generation records across Australia, according to the latest monthly data from Rystad Energy, including for the country’s main grid, the National Electricity Market (NEM).

Rystad senior analyst in Australian renewables and power David Dixon says a new record of 3.74 terawatt-hours (TWh) was set for wind generation in the NEM in July, surpassing June 2023’s record of 3.07 TWh.

Monthly wind generation records were also set in four states, led by Victoria with an output of 1,516 gigawatt-hours (GWh) for July. In New South Wales, a new monthly record of 858 GWh was set, followed by 745 GWh in South Australia and 462 GWh in Queensland.

For wind and solar, July 2025 ends with all Australian large-scale PV and wind assets generating 5,177 GWh, up 23 per cent from 4,221 GWh for the same month last year.

As you can see in the chart below, the top performing wind energy assets for the month were mainly in NSW and Victoria, but Western Australia topped the charts with a 58 per cent capacity factor (CF) for Potentia Energy’s Flat Rocks wind farm.

In second and third spot for the best performing wind farms for July are EDL Energy’s Cullerin Range wind farm in NSW (51% CF) and Iberdrola’s Woodlawn (51% CF).

For large-scale solar, it was all about the Sunshine State in July, with Metka-owned Moura wind farm topping the charts with a capacity factor of 26 per cent, followed by X-Elio’s Blue Grass solar farm (24% CF) and Hana Financial’s Columboola solar farm (24% CF).

Indeed, all but three of the top performing solar assets for the month are Queensland projects.
