Rooftop solar meets 99.9% of South Australia electricity demand

On August 31, 2026, rooftop solar met 99.9% of South Australia's total electricity demand at 1:30 p.m., reducing grid-scale generation to just 2 MW—a new winter record—while the broader National Electricity Market hit a record winter minimum operational demand of 11,992 MW.

This peak was achieved during mild, clear winter conditions on a specific date; the region's renewable energy system remains integrated with the broader NEM.
