Australian Utility Solar Sets State Records as PV Curtailment Nearly Halves
Curtailment of utility-scale photovoltaic (PV) output in Australia's National Electricity Market fell to 168 GWh in August 2026 from 284 GWh in August 2025, according to pv magazine, which described the reduction as significant.
Three states posted record monthly utility PV generation over the same period. New South Wales delivered 684 GWh, Queensland 665 GWh and Victoria 213 GWh, pv magazine reported.
On a combined solar and wind basis, Victoria led all states with 1,387 GWh of utility generation in August 2026.
Rystad Energy analyst David Dixon said Australia's utility-scale solar and wind assets together produced 4.99 TWh in August 2026, a 3% increase on the 4.86 TWh recorded in August 2025.
Project financing also moved during the month. More than 1 GW of utility generation and storage assets reached financial close in Australia in August 2026, according to pv magazine.
The curtailment figure is the sharper of the two operational data points: at 168 GWh, the volume of utility PV energy spilled rather than delivered was well below the 284 GWh recorded a year earlier, even as state-level generation records were set. Curtailment occurs when renewable output is cut back because network capacity or demand cannot absorb it, so the year-on-year drop indicates more of the available solar resource reached the market.
The aggregate generation increase of 3% is modest against the state records, reflecting the mix of solar and wind in the 4.99 TWh total reported by Dixon. Victoria's position at the top of the combined solar and wind table with 1,387 GWh sits alongside its 213 GWh of utility PV, the smallest of the three record-setting PV figures.
