Commodity Demand — QLD1: Saturday 18 July 2026
Queensland demand sits at 5,791 MW as of 06:30 AEST, with spot price at $58.62/MWh — down sharply from the overnight morning peak. Demand has already retraced from this morning's high of 7,268 MW (recorded around 18:00 AEST market time, 08:00 UTC), which coincided with the session's price peak of $85.37/MWh. That roughly 25% swing in demand between trough and peak drove prices from negative territory up to the mid-$80s, confirming QLD's price curve remains tightly coupled to load: every 500 MW step up through the 5,000-7,000 MW band added roughly $10-15/MWh to the RRP.
The overnight period was dominated by negative pricing, with RRP troughing at -$6.50/MWh around 01:05 AEST as demand fell below 3,900 MW — a function of minimal underlying load meeting continued wind output (1,134 MW currently) and black coal baseload (5,054 MW) that doesn't ramp down instantly. As demand climbed through the 05:00-08:00 AEST window, prices flipped positive and accelerated quickly once load crossed 5,500 MW, hitting $78-85/MWh through the mid-morning demand plateau near 7,000-7,200 MW.
Looking at today's forecast trajectory, demand-driven price signals point to another firming period ahead: forecast RRP climbs from $39.75/MWh at 16:00 AEST (target time) to $67.83-78.51/MWh through the 17:00-20:00 AEST evening window as the demand curve rebuilds. AEMO's forecast RRP profile shows a secondary peak near $85.39/MWh around 19:00 AEST target time, mirroring this morning's pattern — a predictable evening ramp as solar drops away and rooftop PV contribution fades, even though grid-scale solar generation in this dataset shows negligible output (0.1 MW), reflecting the overnight/early-morning snapshot.
On demand-side factors, no specific market notices point to unusual load events today — the active notices largely relate to network outages (Tailem Bend capacitor bank in SA, historical Directlink and transmission line restorations in NSW) rather than QLD demand-side interventions. However, the 16 July QLD-region AEMO direction (clause 4.8.9(a1)(1)) remains listed as active, a reminder that generator dispatch instructions have
