Sunday trade across the NEM followed a familiar weekend pattern — overnight prices softened with demand troughs across all regions before the morning ramp took hold. Queensland saw prices move into negative territory overnight before recovering to $79.92/MWh by 06:30 AEST as demand climbed from ~4,465 MW to 6,457 MW. Victoria tracked a similar arc, bottoming near 2,800 MW overnight and lifting to 5,031 MW at $79.72/MWh through the morning ramp. Tasmania was the regional outlier, with spot at $106.02/MWh and demand at 1,108 MW at 06:30 AEST. Watch SA pricing through the afternoon — the $74–$110/MWh band has held firm for most of the session and wind output will be the key variable heading into this evening.
Tasmania — 100% renewable window and elevated pricing. Between 07:30–08:00 AEST, TAS1 achieved 100% renewable penetration, with hydro running at approximately 530–550 MW and wind contributing 53–81 MW. Gas OCGT was fully offline across those intervals. Spot held at $96.22/MWh throughout — firm but orderly. TAS1 posted the highest 24-hour average in the NEM at $98/MWh with a daily peak of $140/MWh, well above mainland region averages. The QNI interconnector also shaped broader market dynamics, with 317 MW flowing south from Queensland into NSW at last read.
Western Australia's wholesale electricity market traded in a notably tight band through the past 24 hours. WA1 averaged $87/MWh with a daily high of just $89/MWh — the narrowest peak-to-average spread of any region covered today. Conditions were settled and unremarkable, with no significant events or constraint activity reported. WEM continues to operate independently of NEM dynamics, as expected.
LOR: No Lack of Reserve conditions are forecast across the NEM in the next 48 hours per the latest STPASA run — a clean outlook through the coming working week. Gas hubs: Short-term trading market prices firmed slightly day-on-day at Sydney ($10.
