commodity demand tas — TAS1

Tasmania's spot price sits at $88.14/MWh with demand at 1,002 MW at 06:30 AEST, representing a clean inflection point: demand has rebounded sharply from a midday trough near 840 MW (where prices compressed to the low-to-mid $60s/MWh) and is now climbing back through the four-figure mark as the evening ramp takes hold. The price-demand relationship across today's data is pronounced — the 840–870 MW range through the afternoon consistently produced prices in the $52–$69/MWh band, while the 1,150–1,180 MW range seen during the morning peak (around 18:00–19:30 AEST) held prices anchored near $96.18/MWh, with brief spikes to $107–$118/MWh as demand surged through the 1,090–1,130 MW zone on the way up.

The demand trajectory from here points firmly upward. The current 1,002 MW reading is still 170–180 MW below the morning peak of ~1,180 MW recorded around 18:30–19:30 AEST, and the pattern from the equivalent period in today's data shows demand accelerating at roughly 15–25 MW per 5-minute interval during the evening build. Forecast prices for the 07:00–07:30 AEST window (21:00–21:30 UTC) are converging in the $96–$106/MWh range across multiple AEMO pre-dispatch runs, consistent with demand pushing back into the 1,050–1,100 MW territory. The most recent pre-dispatch reads — issued around 06:02 AEST — are printing $96.16/MWh for the 07:00 slot, suggesting the dispatch engine is not anticipating a significant supply constraint beyond the standard hydro-dominated stack.

Price sensitivity today shows a clear threshold around 1,000 MW: below it, prices fall into the $60–$85/MWh range; above it, the stack tightens and prices lock onto the $96–$97/MWh band with episodic jumps to $107–$118/MWh when demand accelerates quickly through 1,080–1,130 MW. Generation is currently 395.5 MW hydro and 74.2 MW wind, with gas OCGT at zero, indicating Tasmania is operating comfortably within its hydro capacity at present demand levels — but the OCGT sitting idle also means there is headroom in the stack that has not yet been called on. As demand approaches and exceeds 1,100 MW in the next 60–90 minutes, watch for whether dispatch pulls additional hydro or whether interconnector flows from Victoria adjust to cap local price pressure.

No market notices directly affect Tasmania today. The SA contingency reclassifications and intervention events in the notice register are confined to that region and carry no direct constraint implication for TAS1 or Basslink flows based on current data.
