Friday night into Saturday delivered a split NEM: Tasmania averaged $81/MWh on constrained hydro export capacity, while Victoria and South Australia spent most of the past 24 hours in negative or near-zero territory — SA averaging just $2/MWh with sustained negative prices through the morning low-demand window. NSW1 ($55/MWh avg) and QLD1 ($53/MWh avg) tracked closer to mid-market levels, each spiking modestly into the $73–$77/MWh range during evening demand peaks before easing. For today, the Sunday low-demand profile is already in play: SA spot was sitting at –$2.18/MWh and VIC at –$2.29/MWh at 06:35 AEST, with demand well below daily peaks. Watch the late-afternoon shoulder ramp — VIC1 peak demand reached 5,409 MW at 19:00 AEST yesterday — for any price recovery heading into Sunday evening.
Tasmania's grid reached 100% renewable penetration during the early evening of 2 May, with hydro (387 MW) and wind (56 MW) covering the entire regional load and no gas-fired capacity online. Spot prices held at approximately $73–$74/MWh through those intervals — orderly conditions with no significant volatility. By 06:35 AEST this morning, TAS1 was trading at $84.62/MWh against demand of 944 MW, well below the intraday peak of 1,148 MW recorded at 18:00 AEST. Tasmania's carbon intensity registered at 0.00 tCO₂/MWh this morning. Two interconnectors remain binding: the VIC–NSW link is pinned at its 1,061 MW export limit, continuing to shape the price spread between those two regions.
The WA Wholesale Electricity Market averaged $100/MWh over the past 24 hours, with a maximum of $105/MWh — notably firmer than most NEM regions for the period. No
