Commodity Demand — TAS1 — Wednesday 6 May 2026

Tasmania's spot price sits at $107.47/MWh with demand at 1,181.57 MW as of 06:30 AEST, placing the region firmly in the evening ramp-up that has been building since the mid-afternoon trough. The demand-price relationship today has been tightly correlated: the overnight low of around 919 MW (13:00–13:30 AEST) corresponded to prices in the $75/MWh range, while the morning peak near 1,270 MW at 17:50–18:00 AEST drove prices to a session high of $117.31/MWh. The current reading is tracking that same pattern as demand climbs again through the post-18:00 AEST evening load period, with price responding in near-lockstep — each demand increment above roughly 1,150 MW has consistently pushed the RRP above $100/MWh today.

The mid-session period between 12:30 and 15:30 AEST was notable for price stability in the $87–88/MWh band as demand held 960–1,090 MW, suggesting that band represents a comfortable dispatch zone. The sharp drop visible at 10:40–10:50 AEST — demand fell abruptly from 1,172 MW to 1,061 MW with prices falling to $88.22/MWh — was transient, with demand and price both recovering within 15 minutes, pointing to a brief industrial or interruptible load event rather than a structural shift. The current temperature of 5.2°C with a heating demand index of 12.8 and a forecast maximum of only 10.6°C today is sustaining elevated residential and commercial heating load, which underpins the evening demand trajectory.

Looking ahead, forecasts for the 07:00 AEST (21:00 UTC) interval are converging tightly at $88.16–$88.26/MWh, implying the dispatch model anticipates demand easing back into the 1,050–1,100 MW zone as the evening progresses past the peak. However, the 07:30 AEST (21:30 UTC) forecast is notably more dispersed — earlier runs were placing it at $135–155/MWh, with the most recent runs settling closer to $106–125/MWh — indicating residual uncertainty about whether this evening's demand will sustain above 1,200 MW long enough to tighten the supply stack further. With wind currently contributing 178.8 MW and hydro at 380.32 MW, Tasmania's generation mix is operating well below its hydro capacity ceiling, so the price outcome at peak will hinge on dispatch scheduling decisions rather than supply availability.
