Commodity Demand — TAS1: Sunday 6 September 2026

Tasmania spot price sits at $57.36/MWh at 06:30 AEST, with demand at 1,106 MW and climbing — up from a 925 MW trough around 01:00 AEST overnight. The region has already worked through a pronounced morning demand ramp, with load building from roughly 830 MW in the pre-dawn low (03:00-04:00 AEST) to over 1,160 MW by 08:30 AEST, and price responded sharply: intervals below $15/MWh in the early hours gave way to a sustained $85-98/MWh band once demand cleared 1,100 MW. That morning peak block (08:00-11:00 AEST) held prices near the mid-$90s/MWh for nearly three hours, confirming Tasmania's price curve steepens materially once demand pushes past the ~1,050-1,100 MW mark.

The forecast trajectory points to a second, larger price escalation ahead. AEMO's projections show forecast RRP climbing from $64.76/MWh at 07:00 AEST to a peak of $99.24/MWh around 09:30 AEST, easing only slightly through the late morning before a further push toward $95-96/MWh near midday (11:30-12:30 AEST). This aligns with the historical pattern already visible in today's price history, where the 09:00-12:00 AEST window consistently cleared above $80/MWh, with spikes into the high $90s. Traders should treat the 08:00-12:30 AEST window as the primary price-risk period today, with afternoon prices forecast to soften into the $60-70/MWh range by 14:00-18:00 AEST as demand eases back toward 900 MW.

Overnight demand-side conditions were unusually soft, with multiple 5-minute intervals settling below $15/MWh and several negative or near-zero prints between 23:00 AEST and 05:00 AEST — consistent with minimum load conditions rather than any binding network constraint. No non-conformance or intervention notices are currently active for TAS1; the only regional network item is a now-cancelled lightning-related contingency reclassification on the Gordon-Chapel St line from 5 September, with no live operational impact. Hydro is carrying 958 MW of generation (91.7% renewable share at last dispatch), supplemented by 414 MW wind and 124 MW gas OCGT, indicating the OCGT unit is already responding to the morning demand ramp rather than sitting idle.

Cool overnight temperatures (8.1°C, heating demand index 9.9) explain the early-morning load build, and today's forecast max of 14.2°C with only moderate solar potential (10.7%) suggests limited rooftop PV offset through the day. Combined with light wind potential (2.4%), Tasmania's generation stack will lean heavily on hydro dispatch to manage the midday demand peak — a factor likely underpinning the elevated forecast prices through the 09:00-12:30 AEST window as water-value considerations interact with rising load.
