Commodity Demand — QLD1: Wednesday 9 September 2026
Queensland spot price sits at $102.74/MWh at 06:30 AEST, with demand at 6,394 MW and climbing through the evening peak. This follows a textbook demand-price curve for today: overnight demand troughed near 3,900 MW between 10:00-11:00am AEST (pricing collapsed to $0-$13/MWh in that window), then built steadily through the day to a first peak above 7,550 MW just after 6:00pm AEST, where prices hit $105-107/MWh. The current 6,394 MW reading reflects the evening secondary ramp as the market moves past 8:00pm AEST, with price and demand rising in lockstep — a $20/MWh gain over the past 30 minutes tracking a 300 MW demand increase.
The demand-price relationship today is unusually tight and linear. Every major price inflection matches a demand inflection: the $0/MWh floor coincided with the 4,100-4,900 MW overnight trough, the climb to $90-105/MWh band tracked demand's rise through 6,500-7,500 MW during the 8:00am-11:00am AEST block, and the current uptick mirrors demand pushing back through 6,300+ MW. This suggests the region is operating without significant surplus capacity buffering the demand curve — each MW of load is moving price more than usual for QLD, consistent with black coal carrying 5,453 MW of the 7,265 MW generation mix and limited headroom from hydro (197 MW) and batteries (414 MW) to smooth peaks.
Forecast demand and pricing for the remainder of today show the evening peak has effectively passed its highest point (~7,550 MW near 6:00pm AEST was the daily maximum), with AEMO's forward curve showing prices easing to $63-83/MWh by 9:00-10:00pm AEST and continuing down to sub-$40/MWh overnight troughs by midnight-2:00am AEST tomorrow. The forecast then shows a fresh ramp tomorrow morning, with prices projected back above $95-102/MWh by 8:00-9:30am AEST as demand rebuilds — a repeat of today's pattern. Wind is contributing 1,068 MW currently and renewable penetration sits at 23.6%, below the 49.4% score average for the period, meaning thermal and battery dispatch are setting the marginal price through this evening ramp-down.
No demand-side notices are active for QLD specifically today — the market interventions and directions logged over the past 24 hours (TORRENS ISLAND direction, SA voltage foreseeable intervention) are confined to the SA region and don't carry direct implications for QLD supply-demand balance. Traders should watch the 8:00-9:30pm AEST window for any late demand surprise given the current upward price momentum, though the forward curve implies this is the tail of today's peak rather than a new demand driver.
