Commodity Demand — TAS1: Monday 11 May 2026
Tasmania's spot price sits at $106.24/MWh at 06:30 AEST with demand at 1,152 MW and rising. The price-demand relationship is tracking the classic autumn evening ramp: demand troughed near 935 MW around 02:10–02:15 AEST at $96.22/MWh, held a flat $96.24/MWh floor through most of the overnight and midday period, then stepped to $106.24/MWh as demand climbed back above 1,130 MW from 06:20 AEST onward. That $10/MWh price step appears to be a consistent dispatch threshold in today's market — the $96.24/MWh floor dominated for roughly 16 hours across the low-demand trough, while the $106.24/MWh level activates reliably once demand pushes above approximately 1,100–1,130 MW.
The demand profile today has traced a clear double-peak shape. The first peak reached 1,373 MW at 06:05 AEST (the overnight-to-morning peak), with a secondary morning commercial peak at 1,367 MW around 07:00–07:05 AEST. Demand then eased through the midday period, hitting a secondary trough near 956 MW at 01:00 AEST and a brief anomalous dip to 848 MW around 01:05–01:30 AEST — likely a data artefact or a short-duration demand response event — before recovering. With demand now at 1,152 MW and climbing through the evening, the trajectory is consistent with Tasmania's standard autumn weekday profile heading into the 07:00–09:00 AEST commercial ramp.
The evening demand trajectory is the key price driver for the rest of today. Forward forecasts for the 07:00 AEST (21:00 UTC) interval show $96.24/MWh consensus across nearly all runs, suggesting AEMO's pre-dispatch does not anticipate demand breaching the upper dispatch stack threshold before that interval. However, given demand is already at 1,152 MW at 06:30 AEST and the standard autumn morning peak sits in the 1,350–1,375 MW range, traders should expect the price to cycle between $96.24/MWh and $106.24/MWh through the 07:00–09:00 AEST window as dispatch clears against the next generation step. Generation is currently 741.79 MW hydro and 57.54 MW wind, with gas OCGT at zero — the absence of gas peaking capacity in dispatch today keeps the price ceiling anchored at the current $106.24/MWh level unless demand substantially overshoots the morning peak seen earlier in the session.
Weather is the remaining demand wildcard. Temperature sits at 10.7°C with 99% cloud cover and a heating demand index of 7.3, consistent with the 935–1,370 MW demand range observed today. Tomorrow's forecast maximum of 15.8°C and improving solar potential suggest the afternoon demand trough could be slightly deeper on Wednesday, with the overnight heating load moderating. No Tasmania-specific market notices are active that would restrict interconnector capacity or alter the dispatch stack today, so the Basslink flow position remains the primary variable for whether local price diverges from the mainland during any demand surge.
