Regional Outlook — TAS1: Saturday 30 May 2026

The spot price sits at $81.76/MWh as of 06:30 AEST, with total demand at 899.78 MW — a notable step down from the overnight peak above 1,200 MW seen during yesterday's morning ramp, which briefly pushed prices to $131.33/MWh at 17:25 AEST. Across the 24-hour price history, the weighted average has tracked in the $87–103/MWh band for most of the day, with the current reading representing one of the softer prints in that window. Demand is easing on a cool Sunday morning (current temperature 6.5°C, heating demand of 11.5 kWh equivalent), and with no solar generation active, the load profile is flatter than it will be mid-afternoon.

Tasmania's generation mix is entirely emissions-free at the current dispatch interval: hydro is contributing 578.19 MW and wind 407.91 MW, with gas OCGT sitting at 0 MW. Combined output of 986.10 MW comfortably covers the 899.78 MW load, implying surplus capacity available for export via Basslink to Victoria. Carbon intensity sits at 0 tCO₂/MWh and renewable penetration is 100%, a position the region has held continuously across the entire 24-hour carbon history. With current wind potential rated at 0.7 out of a possible scale and today's forecast averaging 2.0, wind output may ease slightly across the day. Solar potential averages 4.4 today against a partly cloudy 38% cloud cover outlook, though given Tasmania's latitude and winter season, the contribution remains minimal.

Predispatch forecasts point to prices settling in the $83–87/MWh range through tonight's trading intervals (07:00–08:30 AEST), consistent with the current softening trend as Sunday demand stays subdued. The lowest forecast window across the load schedule falls around the 09:00–10:00 AEST range (23:00–00:00 UTC), where multiple predispatch runs are pricing at $73.83–$74.10/MWh — rated "good" quality by the model. Prices are then expected to climb back toward $85–87/MWh through the early hours of tomorrow as demand builds into the working week. The sharpest value opportunity for flexible load or storage dispatch today is centred on that late-morning AEST trough window.

There are no active market notices directly affecting Tasmania or the Basslink interconnector (T-V-MNSP1). The notices in the feed relate to contingency reclassifications in VIC1 (Yallourn–Rowville 220 kV lines, now resolved), inter-regional transfer variations affecting VIC and SA, and routine AEMO market systems maintenance. Traders should note the Heywood transformer returned to service on 29 May, restoring full VIC–SA interconnector capacity, which indirectly benefits Tasmania's export stack through improved mainland grid headroom. No low-reserve conditions are currently declared anywhere in the NEM per the latest MTPASA notice dated 19 May.
