Sunday's NEM traded broadly within normal winter ranges overnight, with NSW1 averaging $80/MWh (peak $121/MWh) sitting as the priciest mainland region across the 24-hour window. Early-morning demand ramps are well underway: Queensland reached 6,631 MW by 06:30 AEST after troughing near 4,716 MW overnight, while Victoria's demand stood at 5,805 MW with spot at $51/MWh — still recovering from mid-afternoon near-zero prints during the solar oversupply window. Watch for the VIC–NSW interconnector: it was the sole binding interconnector at 06:30 AEST, flowing 508 MW northward into NSW, which may sustain the NSW premium into the morning peak build.
Tasmania is the standout. During the 20:10–20:30 AEST window on 28 June, TAS1 achieved 100% renewable generation — hydro contributing approximately 2,936 MW and wind 399 MW — with no fossil fuel dispatch required to meet regional demand. RRPs held steady at $70.20/MWh through those settlement periods, demonstrating that the milestone carried no material price disruption. Carbon intensity for the region registered 0.00 tCO₂/MWh during that window. South Australia also recorded 96.5% renewable penetration on the day, with wind averaging 1,663 MW and RRPs falling sharply to $33.77/MWh within a single five-minute period. VIC1 briefly touched negative pricing (–$0.05/MWh) across two intervals at 16:55–17:00 AEST amid high wind and steady baseload output.
WA1 was the highest-priced region across both markets over the 24-hour period, averaging $104/MWh with an intraday peak of $233/MWh — significantly above any NEM region. No further granular event data is available for WEM at this publication time; energy managers with WA exposure should monitor dispatch reports directly for intraday context.
LOR: No Lack of Reserve conditions are forecast across the NEM in the next 48 hours per STPASA. Gas: Short-term trading market prices eased noticeably today — Brisbane STTM fell to $11.17/GJ from $13.03/GJ yesterday; Sydney dropped to $10.35/
