NEM-wide prices tracked a textbook autumn diurnal pattern overnight — demand troughed across all regions in the early hours before climbing through the morning ramp. By 06:30 AEST, SA1 was sitting at $125/MWh, VIC1 at $103/MWh, TAS1 at $106/MWh, and QLD1 at $86/MWh. The QNI interconnector is running at its import limit of −590 MW (fully bound), shaping the QLD–NSW price spread. Watch SA1 and VIC1 through the afternoon shoulder — both regions showed $125–$138/MWh peaks during yesterday's evening band and conditions are similar today.
Tasmania is the standout region in today's brief. TAS1 recorded 100% renewable penetration during the early evening, with hydro running at approximately 742–857 MW and wind contributing up to 58 MW — zero gas-fired output. Simultaneously, a major binding network constraint — T_BLINK_TV_NGZ — registered a shadow price of $7,308,000, one of the more significant constraint events seen in the region recently. Despite the severity of that constraint, wholesale prices remained comparatively measured, peaking at $105.63/MWh at 08:00 before settling back to the ~$96/MWh range, indicating the constraint was acting on network flows rather than directly lifting spot. TAS1's 24-hour average settled at $98/MWh — the highest NEM average across the day.
The WA Wholesale Electricity Market continued trading at a premium to eastern states, with WA1 recording a 24-hour average of $107/MWh and a comparatively narrow range — max
