Load Advisor: Monday 15 June 2026
NEM-wide spot prices sit at $70.61/MWh in NSW, $70.84/MWh in QLD, and $69.18/MWh in TAS as of 06:30 AEST, while VIC and SA are already at or below zero (-$0.10/MWh and -$0.09/MWh respectively) on 5,381 MW and 1,494 MW of demand. WA is the outlier at $112.41/MWh. The strongest immediate load-shifting signal is in VIC and SA, where prices will remain deep in excellent territory through the overnight period before a secondary negative-price window opens this afternoon.
The best windows by region are as follows. **VIC** offers the most sustained opportunity: prices will drop to $5.08/MWh at 11:00 AEST, flatten near $10.50/MWh through to 16:30 AEST, then turn negative from 23:30 AEST (reaching -$3.21/MWh by 04:00 AEST tomorrow) — the afternoon negative-price window running 23:30–04:00 AEST is the standout slot NEM-wide, with savings of up to $66.96/MWh against the current price. **SA** mirrors this pattern closely: prices will dip to $5.03–$5.88/MWh around 23:00–23:30 AEST, then go negative from 23:30 AEST, bottoming at -$3.00/MWh by 04:00 AEST (savings up to $68/MWh). **NSW** will see its cheapest window between 13:00–14:30 AEST at $26.44–$28.95/MWh, representing $44–$56/MWh savings against daytime peaks forecast at $79–$83/MWh from 16:00 AEST onwards. **QLD** offers a narrower overnight trough at 13:30–14:30 AEST ($26.12–$28.91/MWh) but faces a sustained peak from 16:00–04:00 AEST at $75–$91/MWh — load should be pulled well forward of 16:00 AEST or deferred past that block entirely. **TAS** presents the weakest case, with prices anchored near $59–$65/MWh across virtually the entire forecast horizon and savings confined to a modest $15–$22/MWh band; only the 04:00 AEST slot at $59.65/MWh offers marginal relief.
Periods to avoid are clear: NSW and QLD both face morning ramps from 16:00–18:30 AEST with forecasts of $77–$91/MWh; VIC jumps sharply from $10.65/MWh at 16:30 AEST to $54–$64/MWh between 17:00–19:30 AEST; and SA spikes from sub-$20/MWh to $43–$65/MWh across the same 16:00–20:00 AEST window. Full-cloud cover across VIC, SA, and TAS today with temperatures ranging 8–17°C will sustain heating demand through the day, underpinning those morning and evening peaks.
