Regional Outlook — VIC1: Sunday 17 May 2026

The spot price in Victoria sits at $226.51/MWh at 06:30 AEST, with total demand at 5,266 MW and climbing. That price represents the upper end of a volatile overnight range: intervals tracked between roughly $97/MWh and $244/MWh across the past 24 hours, with a sustained elevated band of $130–$190/MWh through the early morning peak and a brief spike to $244/MWh at 17:00 AEST. The grid stress score of 82.2 reflects that tightness — this is not a relaxed market open. Murraylink remains offline following an unplanned outage of the Redcliffs converter station (Market Notice 144097/144099), removing the SA–VIC interconnector from the dispatch stack and constraining Victoria's import flexibility.

The generation mix at the latest interval (05:55 AEST) shows brown coal supplying 1,580 MW, gas OCGT at 274 MW, wind at 258 MW, hydro at 17 MW, and battery discharge contributing 16 MW. Solar output is zero, consistent with pre-dawn conditions and today's 100% cloud cover. Renewable penetration sits at 13.61% with carbon intensity at 0.9811 tCO2/MWh — up from the daytime low of 0.667 tCO2/MWh recorded around 17:55 AEST when wind was stronger and solar was contributing. With wind potential rated at just 0.1 today and overcast conditions limiting solar throughput (average solar potential of 2.5 for the day), the mix is unlikely to shift materially toward lower-carbon sources during daylight hours.

Predispatch signals are uniformly bearish for buyers across the morning. Forecasts for the 07:00 AEST interval (21:00 UTC) centre in the $250–$278/MWh range across all recent predispatch runs, with the 07:30 AEST half-hour similarly priced at $260–$277/MWh. The 08:00 AEST period steps higher, with multiple predispatch runs pointing toward $280–$360/MWh, and the 08:30–09:30 AEST window carrying forecasts as high as $359–$374/MWh. That escalation is consistent with Monday morning commercial demand loading onto a grid already operating without Murraylink, with low wind, and with brown coal and gas carrying the bulk of the stack. Large energy users with flexible load should note the extended elevated window — the predispatch curve does not show material relief until the 10:00–11:00 AEST range, where prices ease toward $277–$330/MWh.

The most directly relevant active notice for Victorian traders is the Murraylink outage (I-MURRAYLINK / I-ML_ZERO constraint sets invoked), which removes the SA–VIC flow path and tightens the VIC dispatch envelope. A non-conformance notice for Loy Yang A Unit 2 (LYA2, -16 MW, 15 May) is still listed as active but predates today's conditions and is not considered material to this morning's dispatch. The Upper Tumut units 1–4 trip in NSW (non-credible contingency event, 14 May) warrants monitoring for any residual constraint flow effects on the VIC1–NSW1 interconnector, though no direct V
