A record-breaking month of renewable energy generation has been set in three different states across Australia in May, new data reveals, as solar and wind continue to push down spot prices on the electricity market and batteries continue to smooth price volatility.

Rystad Energy reports that Australia’s large-scale solar and wind assets generated a total of 4.6 terawatt-hours (TWh) over the month of May, up 10 per cent from 4.2 TWh in May 2025.

And despite May 2026 featuring the worst wind and solar drought on Australia’s main grid since 2022, four new records were set: Wind generation for the month of May in Victoria of 1,079 gigawatt-hours (GWh) and Queensland (625 GWh), and utility PV generation for the month of May in NSW (549 GWh) and Queensland (538 GWh).

At a state level, Victoria took out top spot for utility solar and wind generation combined, at 1,218 GWh combined, including 139 GWh from utility PV and 1,079 GWh from wind.

Rystad’s top-performing wind assets for the month were mostly in Queensland and Western Australia, although the project in number one spot for capacity factor (CF) was the 175 megawatt (MW) White Rock Wind Farm in Glen Innes, NSW, at 45.6% CF.
