Commodity Demand — NSW1: Friday 15 May 2026
NSW spot price sits at $81.53/MWh at 06:30 AEST with demand at 6,822 MW — well below the intraday peak of 9,112 MW reached around 17:55 AEST during the morning demand surge. The price-demand relationship across today's trading has been textbook: the morning ramp from around 06:30 AEST drove prices from the high-$30s into the $76–$87/MWh band as demand crossed 8,000 MW, held in that range through the 9,000+ MW plateau between approximately 17:30 and 18:00 AEST, then softened progressively as demand fell away through the afternoon and evening. The current 6,822 MW demand level reflects the Saturday post-evening lull, with today being a weekend driving the demand profile lower than comparable weekday peaks — the intraday high of ~9,112 MW is notably below what a mid-week winter morning would typically produce.
Price sensitivity has been clearly tiered across the day: demand in the 6,300–6,900 MW range has cleared broadly in the $40–$70/MWh band; demand above 8,500 MW has consistently attracted prices in the $76–$88/MWh range. The brief excursion above $95/MWh during the 07:15–08:30 AEST window (demand 8,400–8,450 MW) coincided with the steepest part of the morning ramp where marginal supply was tightest. The afternoon demand trough between approximately 02:30–03:30 AEST (6,300–6,580 MW) cleared at $40–$67/MWh, confirming a relatively elastic supply stack in that demand range on a Saturday.
Looking ahead, forecast prices for the next few intervals sit at $82.69/MWh for 07:00 AEST, stepping down toward the $61–$77/MWh range across the broader overnight window. Demand is currently trending fractionally upward from the 6,791 MW trough seen around 05:20 AEST, consistent with early-morning Saturday heating load in 13°C and fully overcast conditions. Today's weather profile — 100% cloud cover eliminating solar generation (solar is currently contributing just 141 MW) and a low wind potential score of 0.4 — means the generation mix is weighted toward black coal (4,651 MW) and wind (872 MW), with hydro (464 MW) and battery (118 MW) providing the balance. With solar suppressed all day by 96% average cloud cover forecast, there is no midday demand offset to drive the price dip typical of autumn weekdays, which supports prices staying in the $56–$80/MWh corridor through the bulk of today's daylight hours rather than dipping into the $30s as solar would normally enable.
The key demand-side notice for NSW is the Directlink No. 2 Leg return to service at 14:10 AEST, which restored interconnector capacity on the N-Q-MNSP1 and lifted the N-MBTE_1 constraint. This improves Queensland import headroom during any demand resurgence, providing modest downward price pressure at the margin should this evening's demand — currently building from the 6,822 MW base — approach the 7,500–8,000 MW range typical of Saturday evenings in mid-autumn.
