regional tas — TAS1
The spot price in Tasmania sits at $65.22/MWh against a total demand of 1,002 MW as of 06:30 AEST this morning. That price is well below the sustained peak of $106–$140/MWh seen during the 16:30–18:00 AEST window overnight, and represents a clear post-peak retreat. The 24-hour price trend shows a sharp morning ramp — prices climbed from around $65/MWh at midnight to a session high of $140.02/MWh at 16:30 AEST before easing through the evening back toward current levels. Demand has also pulled back from its overnight peak of approximately 1,200 MW, consistent with a Saturday morning profile.
The generation mix is entirely renewable: hydro is contributing 302.58 MW and wind 34.56 MW, with gas OCGT at 0 MW. Carbon intensity sits at 0 tCO2/MWh with renewable penetration at 100%, a position that has been sustained consistently across every 30-minute interval recorded over the past 24 hours. The gap between metered generation (337 MW) and total demand (1,002 MW) indicates Tasmania is drawing substantially from Basslink imports, which is the normal operating mode when local hydro dispatch is modulated for storage or commercial reasons.
Predispatch forecasts point to prices settling in the $65–$72/MWh range through the 07:00–07:30 AEST period, with the most recent forward runs clustering tightly around $71.39/MWh for the 07:00 interval and $65.14/MWh for the 07:30 interval. Load window data indicates off-peak pricing through the early morning hours (10:00–13:30 AEST) with forecast dispatch prices dipping as low as negative $15/MWh around 13:00 AEST, suggesting potential surplus conditions. Prices are expected to ramp again from approximately 15:30 AEST as the Saturday evening demand period approaches.
On market notices: there are no active notices directly affecting TAS1. The significant volume of active notices in the dataset are all directed at QLD1 and relate to repeated reclassification of the Mudgeeraba–Terranora 110 kV double circuit as a credible contingency event due to lightning activity — the most recent reclassification was issued at 04:09 AEST and remains in effect, though no constraint sets have been invoked. A cluster of "Prices Subject to Review" notices covering the 15:05–17:40 AEST intervals yesterday were subsequently confirmed unchanged under Clause 3.9.2B. An AEMO systems notice flags planned maintenance to Cisco ISE servers on 30 April between 12:00–18:00 AEST, with potential minor SSL VPN authentication delays for market participants.
