Commodity Demand — QLD1 — Saturday 9 May 2026

Queensland's spot price sits at $105.04/MWh with demand at 5,826 MW as of 06:35 AEST — a Sunday evening shoulder period that is pushing prices firmly into three figures. The demand-price relationship across today's trading history is sharp and clearly defined: when demand peaked at 7,215 MW around 18:05 AEST, prices were anchored in the $92–$112/MWh range throughout the morning and early afternoon high-demand window (06:00–14:00 AEST). As demand fell through the afternoon — dropping from roughly 7,100 MW at 17:00 AEST to the current 5,826 MW — prices have not retreated proportionally, instead holding above $95/MWh for most intervals since 19:00 AEST. This price stickiness at relatively modest Sunday evening demand levels indicates the dispatch stack is not carrying significant surplus capacity at this stack position.

The daily demand arc today follows a textbook autumn Sunday profile. Demand bottomed out overnight near 3,593 MW at approximately 11:35 AEST, when prices were deeply negative (troughing at -$3.20/MWh), reflecting oversupply against a low floor of consumption. The morning ramp was steep: demand climbed from ~4,965 MW at 15:00 AEST to 7,053 MW by 17:20 AEST — an increase of over 2,000 MW in roughly 2.5 hours — and prices tracked this ramp from $0/MWh through to $107/MWh. That $107/MWh level appears to be a key supply threshold; multiple intervals today have printed at or just above $105–$106/MWh without meaningfully exceeding it, suggesting marginal plant is clearing in a narrow band around that price point under current unit commitment.

Looking at today's remaining trajectory, the most recent forecast for the 21:00 AEST interval (07:00 UTC) has been revised upward to $107.80/MWh — well above earlier forecasts that sat around $77–$82/MWh — consistent with demand continuing to hold in the 5,800–6,000 MW range as the Sunday evening ticks along. Current temperature is 12.4°C with moderate heating demand, which supports sustained residential consumption through the evening. Demand is expected to ease progressively from around 22:00 AEST onward as the overnight trough begins, and forward load window pricing points to prices falling sharply into the $30–$50/MWh range post-midnight, then returning to near-zero or negative territory in the early hours of Monday morning as overnight oversupply conditions re-establish.

One market notice relevant to Queensland demand-side conditions is the increase in the Very Fast Contingency FCAS local dispatch cap in QLD from 200 MW to 250 MW, effective 5 May 2026. This adjustment increases the headroom for frequency response in islanding scenarios and is a minor factor in overall unit commitment costs, but does not materially shift today's demand or price outlook. The Armidale transformer outage (NSW constraint set N-AR_TX) affecting the QNI interconnector remains a background factor limiting northward flow from NSW, which can marginally tighten Queensland's supply position during high-demand intervals.
