Commodity Demand — QLD1 — Monday 4 May 2026

Queensland spot price sits at $82.49/MWh with demand at 6,495 MW as of 06:35 AEST. That current level represents the region well into its morning demand recovery — demand troughed around 4,340 MW in the early hours (approximately 13:15 AEST overnight) before climbing sharply through the pre-dawn ramp. The price-demand relationship today has been tight and consistent: prices held $22–$40/MWh when demand sat below 4,600 MW overnight, then tracked upward in lockstep with demand as the morning ramp accelerated from 14:00 AEST (04:00 UTC), with the most acute price response occurring between 5,800 MW and 6,500 MW where spot repeatedly tested and held the $75–$93/MWh range. The morning peak of approximately 7,785 MW at 07:55 AEST drove sustained pricing at $91–$95/MWh for nearly three hours — a clear indication of tight marginal plant positioning above 7,500 MW.

Demand has since eased from that morning peak toward the current 6,495 MW, consistent with the typical mid-morning pullback as commercial loads stabilise and the pre-lunch lull sets in. Prices have tracked this moderation, stepping back from the $92–$95/MWh band seen between 17:00–21:00 AEST. The forward forecast signals a renewed price escalation this evening: AEMO's most recent pre-dispatch forecasts for the 07:00 AEST half-hour (21:00 UTC) are pointing to $93.35/MWh, with the 07:30 AEST window forecast at $92.73–$120.26/MWh across successive runs. The 08:00–09:00 AEST window carries forecasts in the $100–$124/MWh range, reflecting the anticipated demand surge as the Tuesday morning business peak builds — with today's max temperature forecast of 25.7°C and 94% cloud cover providing minimal solar suppression of that demand ramp.

Two market notices are directly relevant to Queensland's price outlook today. AEMO has invoked constraint set N-MBTE_1 following an unplanned outage of Directlink's No. 3 Leg from 02:30 AEST, restricting the N-Q-MNSP1 interconnector and reducing Queensland's ability to export to or import from NSW at full capacity. This tightens the effective supply envelope available to Queensland dispatchers during peak periods. Additionally, AEMO has confirmed an increase in the Very Fast Contingency FCAS cap for Queensland from 200 MW to 250 MW effective today, reflecting AEMO's assessment that Queensland islanding scenarios remain credible — a factor that imposes incremental FCAS cost uplift on dispatch during periods where the region approaches its interconnector limits.

The demand trajectory through the rest of today points to a second, more sustained peak building from approximately 08:00–09:30 AEST as the full Tuesday business load comes on. With cloud cover at 94% suppressing rooftop solar contribution and the Directlink constraint reducing interconnector flexibility, the supply stack faces this peak with less buffer than a typical Tuesday. Forecast prices in the $100–$124/MWh range for the 08:00–09:30 AEST window are credible given those structural constraints. Load-shedding flexibility or demand response positioned ahead of
