Commodity Demand — QLD1: Tuesday 19 May 2026

Queensland spot price sits at $111.11/MWh with demand at 6,580 MW as of 06:30 AEST — a material step up from the $72–$83/MWh range that prevailed through the afternoon trough when demand bottomed near 5,460 MW between 03:00 and 05:30 AEST. The demand ramp from that trough has been steep and price-responsive: the first move through $111/MWh coincided with demand crossing 6,400 MW around 06:10 AEST, and the trajectory is still climbing. Today's price history demonstrates clear threshold behaviour — spot held below $90/MWh for most of the 5,460–5,750 MW range, then accelerated sharply once demand pushed above 6,200 MW in the post-solar evening climb.

Today's demand profile has followed a textbook winter Wednesday shape: a morning peak near 7,900 MW around 18:00–18:30 AEST, a mid-morning plateau in the 7,000–7,100 MW range through the early hours, then the solar-assisted midday trough dropping demand to a low of around 5,460 MW before the evening ramp now underway. Critically, prices remained well-contained — mostly $72–$83/MWh — through the entire 5,460–7,900 MW morning and afternoon window, suggesting adequate supply stack depth at those demand levels. The price escalation now occurring tracks the evening ramp, where demand is adding roughly 200–300 MW every 30 minutes.

Forward forecasts for the 21:00–21:30 AEST window (07:00–07:30 UTC) are clustering in the $83–$106/MWh range, well below the $177–$231/MWh spikes that appeared in the equivalent period on Tuesday evening. That is a meaningful downward revision from early-day forecasts, which were pricing this window as high as $231/MWh. The moderation reflects either improved supply availability or lower-than-anticipated demand momentum. Weather is supportive of this softer outlook: current conditions show 14.4°C with minimal cloud cover and only 3.6 heating degree units, limiting aggressive heating load. The daily outlook for today tops at 22°C with low cloud cover, pointing to a moderate evening peak.

The key risk factor from market notices is the ST PASA LOR1 declared for QLD on 19 May (covering 06:00–19:30 AEST), citing minimum available reserves of 1,012 MW against a requirement of 1,197 MW. That notice was active across the full demand range today and did not produce sustained high pricing — the LOR1 was effectively resolved by the market through the day without AEMO intervention. With demand now at 6,580 MW and rising into what the data shows is a price-sensitive zone above 6,500 MW, traders should watch whether demand holds below 6,800–7,000 MW as the evening progresses; the history from Tuesday shows that level coincides with $177–$231/MWh outcomes if supply margins are tight.
