Commodity Demand — TAS1: Wednesday 15 July 2026
Tasmanian demand sits at 1,293 MW as of 06:30 AEST, up sharply from the overnight trough near 1,050-1,100 MW and pushing the spot price to $107.78/MWh. The region is tracking a classic winter morning ramp — demand has climbed roughly 240 MW since 04:00 AEST, with price responding non-linearly: intervals above 1,250 MW have consistently printed $100-175/MWh, while sub-1,100 MW overnight troughs saw prices fall to $20-60/MWh and briefly to near-zero. This demand-price coupling reflects Tasmania's reliance on hydro dispatch bidding alongside a 207 MW GAS_OCGT contribution currently in the mix, with gas peaking capacity typically called on as demand climbs through the morning shoulder.
The forecast trajectory is the key story for today. AEMO's price forecasts show a sharp escalation from the current $107.78/MWh into the 07:00-08:00 AEST window, with forecast RRP hitting $457.50/MWh by 07:30 and holding in the $200-260/MWh band through mid-morning. This aligns with the seasonal winter peak pattern — cold outdoor temperatures (7.2°C currently, heating demand index at 10.8) are driving thermal load right as rooftop solar contribution remains negligible (solar potential at 0). The forecast profile extends further into extreme territory around midday, with spikes to $413.93/MWh at 10:00 and $421.22/MWh at 12:00 AEST, before easing back to $75-140/MWh through the afternoon and evening as demand tapers.
Demand itself isn't forecast in the dataset (values show as zero), but the price trajectory implies AEMO expects the current ramp to continue into a sustained morning-into-midday peak, likely exceeding the 1,320 MW intraday high seen yesterday around 08:00 AEST. Traders should note the active credible contingency reclassification on the Gordon-Chapel St 220kV lines (cancelled as of yesterday evening) and the prior LOR1 reserve notice from 13 July — both signal the network operates with tighter margins during Tasmania's winter demand peaks, amplifying price volatility when hydro and gas capacity are stretched.
