A pronounced north-south price split has defined the NEM overnight. Queensland led with a 24-hour average of $74/MWh and a morning peak of $231.70/MWh around 22:10 AEST, while Victoria and South Australia spent most of the session in negative or near-zero territory — Victoria averaging just $2/MWh, SA averaging $3/MWh. Tasmania held firm at an $81/MWh average, anchored by stable hydro dispatch. Three binding interconnector constraints were shaping flows at 06:35 AEST, with the VIC–NSW interconnector the dominant active link. Being a Saturday, southern-region demand is expected to remain subdued through the morning; watch Queensland for any continuation of the elevated price pattern that characterised yesterday's afternoon peak window.
Tasmania's grid achieved 100% renewable penetration during the 17:05–17:35 AEST window on 1 May, with all demand met by hydro (approximately 223–234 MW) and wind (approximately 72–97 MW). Spot prices held between $73.68/MWh and $74.64/MWh across that interval — stable and moderate, with no material price stress. By 06:35 AEST, Tasmania's carbon intensity read 0.00 tCO2/MWh with 263 MW of hydro and 45 MW of wind covering the full 973 MW load. The 24-hour average of $81/MWh and max of $106/MWh reflect a well-supplied, balanced region throughout the day.
The WEM continued to trade at a material premium to eastern states, with WA1 averaging $115/MWh across the 24-hour period and a narrow max of $119/MWh — the tightest high-to-average spread of any region in the dataset today. No intraday volatility events were flagged. Detailed dispatch and constraint data for the WEM are not available in today's feed beyond these price figures.
