Commodity Demand — TAS1 — Saturday 9 May 2026

Tasmania's spot price sits at $88.20/MWh with demand at 1,039.89 MW as of 06:35 AEST, having climbed steadily from the overnight trough of around 856 MW at approximately 13:30 AEST. The demand profile today has traced a clear autumn Sunday pattern: a deep overnight low, a morning ramp through the 06:00–08:00 AEST window that pushed demand to a day-to-date peak of around 1,174 MW, followed by a gradual retreat through the afternoon and early evening settling into the current mid-1,000 MW range. Pricing has been notably sticky to the $88.18–$96.24/MWh band throughout, with the principal price sensitivity emerging not at the demand peak itself but during the midday period — the single interval reaching $104.31/MWh at 22:00 UTC (08:00 AEST) coincided with demand at 1,070 MW, suggesting dispatch stack dynamics rather than raw demand volume are the primary price driver at these load levels. Three brief dips to the high-$60s/MWh occurred near 20:25–20:35 UTC (06:25–06:35 AEST) when demand was around 1,035–1,047 MW, pointing to short-lived surplus conditions on the Basslink interconnector or hydro dispatch adjustments rather than any structural softness.

The evening demand trajectory is now building again, consistent with residential heating load in 7.2°C conditions with a heating demand index of 10.8. Demand has risen from a late-afternoon trough near 930 MW back through 1,000 MW and is currently tracking above 1,039 MW. The most recent AEMO forecast for the 07:00 AEST half-hour prints $91.35/MWh, a modest step up from the prevailing $88.20/MWh, with the 07:30 AEST interval forecast at $96.22/MWh — indicating dispatchers anticipate demand continuing to build into a Sunday evening peak likely in the 1,050–1,150 MW range. Generation is currently 820 MW hydro and 41 MW wind, with gas OCGT at zero, so any material demand lift toward the 1,100–1,150 MW zone that characterised the morning peak will require additional hydro dispatch or Basslink import, both of which carry their own marginal cost implications reflected in that $96.22/MWh forward signal.

The forward price outlook for the balance of today and into the early hours of Sunday 10 May holds largely in the $88.20–$96.22/MWh corridor, with no forecast intervals breaching $100/MWh. The price band is tighter than the intraday spread observed during the morning session, suggesting AEMO's pre-dispatch model sees demand remaining contained below the stress thresholds that triggered the brief $104.31/MWh spike. Weather is a marginal supporting factor: today's forecast maximum of 17.4°C limits cooling demand to near zero, and with wind potential rated at just 0.1 and cloud cover only 4% at present, overnight conditions will sustain heating demand without introducing any renewable variability. There are no active AEMO market notices specific to Tasmania affecting current dispatch, and the earlier LOR1 declared for 5 May has been cancelled, leaving no reserve adequacy concerns on the immediate horizon for TAS1.
