Commodity Demand — TAS1 — Sunday 10 May 2026

Tasmania spot price sits at $103.04/MWh with demand at 1,229 MW as of 06:35 AEST — demand is climbing sharply through the Monday morning ramp, up from an overnight trough of around 890 MW recorded near 13:00–14:00 AEST. The price-demand relationship today is tightly correlated: prices held at the $88–$89/MWh floor during the overnight low-demand period, stepped to $96.24/MWh as demand crossed the ~1,020 MW threshold around 06:55 AEST, and pushed through $100/MWh once demand cleared 1,215 MW from around 07:40 AEST. The mid-morning plateau above 1,240 MW (07:50–09:15 AEST) coincided with repeated prints at $106.22–$106.26/MWh, confirming a clear price band transition at that demand level. A brief sub-$96/MWh interval at 09:20 AEST when demand dipped to 1,219 MW illustrates just how narrow the margin is between the two price tiers.

The afternoon period showed an unusual pattern: demand fell to the low 1,000s MW between 14:00 and 19:00 AEST, yet prices remained locked at $106.22/MWh for sustained periods — decoupling from the demand-price relationship observed earlier. This suggests the pricing reflected supply-side scheduling or Basslink transfer constraints rather than demand pressure alone. Hydro is supplying 828 MW with wind contributing 14 MW; gas OCGT is offline. With no thermal marginal unit setting price, the $96.24/MWh and $106.22/MWh price bands appear to be structural scheduling artefacts rather than a smooth demand-curve response.

Looking ahead through today, AEMO forecasts for the 07:00 AEST half-hour (21:00 UTC) are tightly clustered around $101–$107/MWh across multiple forecast runs, with one outlier at $207.73/MWh from the 13:01 UTC run subsequently revised away — indicating brief dispatch uncertainty that has since resolved. Forecast prices for 07:30 and 08:00 AEST (21:30 and 22:00 UTC) track $106–$115/MWh, consistent with demand continuing above 1,200 MW through the morning peak. The 08:00 AEST temperature of 8°C with 100% cloud cover and a heating demand signal of 10 confirms winter space heating is active and sustaining the elevated demand base. Demand is unlikely to ease materially until mid-morning, keeping prices in the $100–$107/MWh range for the next two to three trading intervals.

Traders should note the two discrete price tiers operating today — $88–$96/MWh below ~1,020 MW and $96–$107/MWh above it — with the current 1,229 MW demand level sitting firmly in the upper band. No Tasmania-specific network notices are currently active that would alter interconnector capacity on Basslink (T-V-MNSP1), though the contingency reclassifications from earlier in the week on Sheffield–George Town 220 kV lines have since been revoked. Absent any Basslink constraint binding, today's price trajectory is demand-driven and consistent with a typical winter Monday morning profile.
