Commodity Demand — TAS1: Sunday 9 August 2026
Tasmania's spot price sits at $63.24/MWh at 06:30 AEST, with demand climbing to 1,229 MW and still rising into the morning ramp. This follows a sharp overnight-to-morning trajectory: demand bottomed near 1,050-1,065 MW around 03:00-03:30, then built steadily through the 06:00-10:00 window, peaking above 1,370 MW at 07:55-08:05 when price pinned at the $88.24/MWh cap for an extended run. The relationship is clear-cut this morning — every 100 MW of demand growth from the overnight trough has pushed price up roughly $25-40/MWh, with the steepest sensitivity between 1,150 MW and 1,300 MW, where hydro dispatch and gas peaking (172 MW OCGT currently online) are both being drawn on to cover the ramp.
Demand is currently easing back from that morning peak, sitting at 1,229 MW and trending down through the evening data window, consistent with the typical Tasmanian shoulder pattern. Forecast pricing points to a firmer evening peak ahead: AEMO's forward curve shows $65.28/MWh at 21:00, stepping up to $88.48/MWh by 22:00 and holding near $88/MWh through 23:00-23:30 before easing. Tomorrow's outlook is more aggressive — forecast prices climb through the 08:00-11:00 window to a $102.51/MWh peak at 09:30 AEST, indicating demand is expected to build faster than today's equivalent morning ramp, likely tightening the hydro-gas balance further.
Overnight, price sensitivity drops away sharply: forecasts show a collapse to $15.10/MWh through the 01:00-07:00 window as demand troughs, with brief dips to $11.76/MWh at 02:30. This is the basis for the identified low-risk load-shifting windows (02:30-07:00 AEST), where average prices of $13-15/MWh offer $87-133/MWh savings versus the daytime peak — relevant for any flexible load or battery charging strategies.
No Tasmania-specific demand-side notices are active today. The three TAS1 network reclassification notices from early August (Norwood-Scottsdale, Palmerston-Hadspen, Sheffield-George Town lines) have all been cancelled, and system conditions are otherwise clear of constraints affecting local demand or price formation. Grid stress reading sits at 68.4, consistent with the current mid-morning ramp rather than any abnormal event.
