Commodity Demand — TAS1: Saturday 6 June 2026
Tasmania's spot price sits at $87.24/MWh at 06:30 AEST with demand at 964 MW — a significant step down from today's peak of 1,278 MW reached around 17:35 AEST, when prices held in the $83–$87/MWh range. The demand-price relationship across today's cycle reveals a relatively compressed price band: even at peak demand above 1,250 MW during the morning period (16:00–18:30 AEST), prices largely remained in the $71–$87/MWh corridor. The sharpest price sensitivity appeared during the pre-dawn period (13:30–16:00 AEST), where demand sat in the 940–980 MW range yet prices periodically spiked to $95–$150/MWh — driven by dispatch-level tightness rather than volume, consistent with a small, islanded grid where marginal unit dispatch can move prices independently of aggregate demand.
The morning ramp (15:30–18:30 AEST) saw demand climb from around 970 MW to 1,083 MW, with prices stepping from $80.20/MWh to a brief $150.04/MWh spike at 16:00 AEST before retreating sharply to $80.20/MWh within one interval. This spike-and-retreat pattern — replicated at lower magnitudes throughout the overnight period — points to tight reserve conditions at the margin rather than sustained demand pressure. Since 04:30 AEST, demand has been easing from the 1,250 MW range toward the current 964 MW, consistent with a Sunday load profile and mild winter conditions (current temperature 12.7°C, heating demand index 5.3).
Forward forecasts for the 21:00–22:00 AEST window (07:00–08:00 UTC) are priced at $87.24/MWh, with the 07:30–10:30 AEST window showing forecast prices stepping up into the $87–$103/MWh range — reflecting the anticipated morning demand rebuild. Today's weather outlook (max 15.9°C, 86% average cloud cover, wind potential 6.2) points to sustained heating demand and limited solar contribution, which will underpin a gradual load recovery through the morning. With wind currently generating 464 MW and hydro at 633 MW covering the full 964 MW load, supply adequacy at current demand levels is not the constraint — the risk is price volatility at the margin during any unexpected demand step-up, as the overnight history demonstrates.
