Commodity Demand — QLD1: Wednesday 17 June 2026

Queensland spot price sits at $78.73/MWh at 06:30 AEST with demand at 6,764 MW — a level that has pulled prices firmly into the upper $70s after the overnight trough. Today's demand profile follows a textbook winter weekday pattern: the dataset shows demand collapsed to a floor near 5,160 MW around 12:05 AEST before the morning ramp began at roughly 15:00 AEST (05:00 UTC), lifting demand through 5,800 MW and driving prices from the high $30s–low $40s range up toward current levels. The price sensitivity to demand is sharp at this point of the supply stack — each 200–300 MW increment above 6,500 MW has been consistently pushing prices from the mid-$60s into the $72–$81/MWh band, with the $80.73/MWh ceiling appearing repeatedly as demand cleared 7,000 MW during the morning peak (17:00–18:00 AEST), where demand reached 7,738 MW.

The morning peak has passed and demand is now in controlled descent, sitting around 6,764 MW and trending toward the midday softer period. The current $78.73/MWh price reflects residual tightness from the overnight-to-morning ramp rather than a fresh demand surge. Weather is a factor: Brisbane is sitting at 10.8°C with a heating demand index of 7.2, which is sustaining residential and commercial loads above typical June levels. Without significant solar potential (currently zero at this hour, 66% cloud cover), the afternoon period will rely on gas OCGT — currently dispatching 935 MW — and batteries at 476 MW to manage the evening ramp.

The forward price strip signals a clear demand-driven arc for the rest of the day. Prices are forecast to hold around $80.72–$80.73/MWh through to 09:00 AEST (23:00 UTC) as demand remains elevated in the 6,500–7,000 MW range, before dropping sharply to $53.75/MWh by 09:00 AEST and then into the $25–$44/MWh band through the overnight trough from 11:00 AEST onward. The critical price event is tomorrow's morning ramp: forecasts show prices stepping from $66.53/MWh at 16:00 AEST (06:00 UTC) to a peak of $105.53/MWh by 19:30 AEST (09:30 UTC), indicating the market anticipates demand clearing well above 7,500 MW during tomorrow's working-day peak — consistent with today's observed price behaviour at equivalent demand levels.

Demand-side participants have a well-defined window: the overnight trough between 11:00 AEST tonight and 15:30 AEST tomorrow offers prices ranging from $23.63/MWh to $39.75/MWh, representing savings of 66–82% against current spot. The MT PASA notice published 16 June confirms no Low Reserve Conditions are identified across the outlook period, so tonight's price softness reflects genuine demand reduction rather than any supply-side constraint.
