Regional Outlook — VIC1: Saturday 16 May 2026

The Victoria spot price sits at $157.23/MWh as of 06:30 AEST, up sharply from the near-zero and negative prices that dominated overnight — the market printed as low as -$11.56/MWh between roughly 01:00 and 04:00 AEST as overnight demand fell to around 3,350–3,500 MW. The morning ramp has driven demand back to 4,469 MW and lifted prices considerably, consistent with the pattern seen across the full price history where the breakfast ramp pushed prices through $100/MWh from around 15:30 AEST and sustained them in the $110–$175/MWh band through the afternoon and evening. Grid stress is elevated, with a score of 75.7/100, and price stability is weak at 35.2/100, reflecting the wide intraday spread.

The generation mix as of 06:00 AEST is dominated by brown coal at 1,601 MW, with battery storage contributing 167 MW — the largest non-coal source currently dispatched. Wind is producing 75 MW, hydro 0.42 MW, and solar is negligible at 0.06 MW given 100% cloud cover and zero solar potential this morning. Both gas OCGT and gas CCGT are at zero output. Renewable penetration sits at just 13.17%, its lowest point in the dataset, reflecting the absence of solar and weak wind. Carbon intensity is 1.0594 tCO2/MWh — the highest recorded across today's data — having climbed steadily from a low of approximately 0.25 tCO2/MWh during the overnight period when wind and battery output were proportionally larger against reduced demand. Today's weather outlook (max 15.9°C, full overcast, minimal wind potential) will keep solar generation negligible and wind output modest for the full day.

The most material active market notice for Victoria is the Murraylink unplanned outage (Notice 144100), with constraint set I-ML_ZERO invoked at 01:45 AEST today, zeroing the V-S-MNSP1 interconnector. This cuts the Victoria–South Australia transfer path via Murraylink, removing a cross-border balancing option at a time when Victoria is reliant on brown coal to carry load. A separate notice (144097) had already flagged a short-notice outage of the Murraylink Redcliffs converter station in Victoria from 20:45 the prior evening, with constraints I-MURRAYLINK invoked. The combination of both Murraylink notices indicates the interconnector is effectively offline; traders should treat Victoria as more electrically isolated from SA than usual for the remainder of the day.

Predispatch forecasts for the next few half-hours point to prices easing from the current $157/MWh level, with the 07:00 AEST half-hour forecast at $121.54/MWh and the 08:00 AEST period forecast in the $110–$123/MWh range. Later half-hours extend into the $125–$154/MWh band, suggesting the market does not anticipate a sustained spike but equally does not expect a return to the cheap overnight pricing. With Murraylink isolated, cloud cover suppressing solar all day, and heating demand (3.3 units) supporting residential load, VIC prices are likely to remain well above the $100/MWh floor through the morning peak and into the evening ramp.
