Commodity Demand — QLD1: Sunday 30 August 2026

Queensland spot price sits at $87.73/MWh as at 06:30 AEST, with demand at 6,499 MW and climbing through the morning ramp. This follows a textbook overnight pattern: demand troughed near 3,760 MW around 02:45-03:00 AEST, dragging price into negative territory (-$7 to -$9/MWh) as minimum demand conditions took hold. From there, demand has risen roughly 2,740 MW in under four hours as the morning ramp kicks in, pulling price up from negative territory through $50-90/MWh as higher-cost plant is dispatched to meet the load.

The demand-price relationship overnight was highly elastic below 5,000 MW — every 100-200 MW move triggered $5-10/MWh swings, and price spent several hours pinned at negative or near-zero levels between 22:00 and 05:00 AEST as demand fell to 3,760-4,700 MW. Once demand crossed roughly 5,600 MW around 06:00 AEST, the market steepened noticeably: price jumped from $25/MWh to over $90/MWh as demand rose through 6,100 MW, indicating the marginal generation stack tightens sharply above 6,000 MW. Peak pricing yesterday's equivalent period hit $99-102/MWh between 08:00-08:30 AEST when demand peaked near 7,225-7,240 MW — that's the level to watch for today's morning peak.

AEMO's forecast trajectory points to a stronger price outcome for today's morning peak than yesterday: forecast RRP climbs from $64/MWh at 07:00 AEST to $95.71/MWh at 07:30 AEST, then $116.30/MWh at 08:00 AEST, with the 08:00-09:30 AEST window holding above $104-116/MWh — roughly 15-20% firmer than yesterday's comparable peak. Price is forecast to ease back through the day to the $62-73/MWh band from midday through the evening, before the next ramp-down into negative territory overnight (forecast turns negative again around 01:00-04:00 AEST tomorrow). Weather offers little demand relief: today's forecast max is a mild 21.8°C with low solar potential (14.7%) and negligible wind (1.2%), meaning minimal rooftop solar offset during the day and limited wind contribution to ease the evening ramp. Current generation mix shows black coal supplying 5,278 MW (the dominant marginal source through this period), wind at 1,249 MW, and batteries contributing 604 MW — with renewable penetration at just 26.5% and carbon intensity at 0.643 tCO2/MWh, both consistent with the low-solar, low-wind conditions driving today's price firmness at the margin.
