Regional Outlook — TAS1 — Friday 1 May 2026

The TAS1 spot price sits at $74.78/MWh with total demand at 973 MW as of 06:35 AEST. That current price is well below the dominant price band that prevailed through the overnight and morning periods, when the RRP was locked in at or near $88.14/MWh across dozens of consecutive intervals — a pattern consistent with a binding constraint on the Basslink interconnector or a hydro dispatch ceiling anchoring the price at a scheduling floor. The 24-hour range spanned from a low of $64.76/MWh to an intraday peak of $105.52/MWh at 16:30 AEST, with that single spike short-lived and pricing quickly reverting. Overnight demand troughed around 800 MW before climbing back through the morning to a peak of approximately 1,168 MW during the 18:00–19:00 AEST window, consistent with a cool autumn Saturday morning heating load now unwinding.

The generation mix at the 06:30 AEST dispatch interval is entirely renewable: hydro is producing 263 MW, wind is contributing 45 MW, and gas OCGT sits at 0 MW. Carbon intensity is 0 tCO2/MWh and renewable penetration is 100%, a position that has been sustained continuously throughout the entire 24-hour price history on record. Current conditions reinforce this: temperature sits at 11.9°C with full cloud cover, near-zero wind potential, and no solar contribution. With wind output modest at 45 MW, hydro is carrying the bulk of Tasmania's internal generation requirement, with the balance of the ~973 MW demand figure likely met via Basslink imports from Victoria — a flow direction consistent with the region's current pricing dynamics.

Predispatch forecasts through to approximately 12:30 AEST today are tightly clustered in the $73.33–$76.90/MWh range, with no significant uplift signalled. Near-term intervals at 07:00–08:00 AEST are forecast at $74.66–$74.70/MWh, and the 08:00 AEST half-hour points slightly to ~$81.28/MWh, suggesting a modest step-up as the business day commences. The 10:30 AEST band forecast at $80.88–$83.65/MWh implies continued gradual firming into mid-morning. Overnight predispatch intervals (12:00–03:30 AEST tomorrow) are forecast in the $73.33–$75.82/MWh corridor — broadly stable and unremarkable absent any supply-side event.

The one active notice requiring attention for TAS1 is a Forecast LOR1 (Lack of Reserve Level 1) declared by AEMO under clause 4.8.4(b) for Tuesday 5 May 2026 between 07:30 and 08:00 AEST. The forecast capacity reserve requirement is 577 MW against a minimum available reserve of only 561 MW — a 16 MW shortfall. While LOR1 does not trigger intervention, it signals tight reserve margins during that window and warrants monitoring as the week progresses, particularly given that weekend wind potential is forecast to remain low (0.5–0.8 average through 4–5 May) and temperatures are expected to fall to minimums of 8.7–10°C by Monday–Tuesday, which could sustain elevated heating demand into
