Thursday night into Friday brought a split NEM: Queensland saw deeply negative prices overnight — troughing at -$7.33/MWh on demand as low as 3,748 MW — before recovering to $93.79/MWh by 06:30 AEST as Saturday morning load built. Victoria held firm above $90/MWh despite relatively modest Saturday demand of 4,889 MW at the same mark. South Australia sustained an elevated price band from around 17:00 AEST Thursday, reaching a spot of $107/MWh at 06:30 AEST against demand of 1,299 MW — well below its earlier peak of 1,831 MW near 18:25 AEST. Interconnector flows are active on four of five monitored NEM links, with none currently binding; the dominant flow is QNI at -909 MW (power moving north, NSW to QLD). Watch SA prices through the morning as demand climbs back toward peak-period levels.
Tasmania recorded 100% renewable penetration during the early evening of 8 May, with hydro contributing approximately 588–653 MW and wind a supplementary 75–118 MW. Gas OCGT units were offline throughout the period. Wholesale prices held steady at ~$88.18/MWh across the vast majority of dispatch intervals from mid-afternoon onward — one of the most consistent price profiles in the NEM on the day. The 24-hour average settled at $87/MWh, with a narrow max of $89/MWh, indicating a well-supplied, stable dispatch stack. Tasmania's emissions intensity registered 0.00 tCO₂/MWh at 06:30 AEST.
The WEM posted the highest 24-hour average across all six regions at $96/MWh, with a contained max of $102/M
