Commodity Demand — VIC1 — Wednesday 29 April 2026

Victoria's spot price sits at $8.15/MWh at 06:35 AEST with demand at 5,025 MW — a significant step up from the overnight trough of around 3,750 MW reached in the early hours, and demand is climbing as the morning ramp takes hold. Today's price-demand relationship has been textbook: prices tracked near zero or negative through the afternoon and evening solar window (demand below 4,100 MW, prices as low as -$0.10/MWh from roughly 02:15–04:00 AEST), then lifted sharply as demand crossed the 4,500 MW threshold around 04:45 AEST and generation mix shifted. The morning ramp from ~4,300 MW at 04:30 AEST to the current 5,025 MW has been accompanied by prices moving from sub-$10/MWh to a current $8.15/MWh — still relatively contained, suggesting supply is keeping pace with the climb so far.

The day's price-demand inflection point is clearly the evening peak. Forecasts for the 07:00 AEST half-hour (21:00 UTC) are pinning the RRP at approximately $33/MWh, a modest lift from current levels, but the 07:30 AEST (21:30 UTC) interval is where the step-change occurs — forecast RRP of $65–67/MWh. This aligns with the historical pattern visible in the data: demand reached 6,200–6,400 MW during the morning peak (around 17:00–18:30 AEST) and prices ran at $74–92/MWh in that band. With current wind generation at 1,156 MW and brown coal at 1,223 MW, the evening demand surge — which will push demand back toward the 5,500–6,000 MW range as residential heating load builds on a 15.6°C autumn evening — will require additional dispatchable capacity to fill the gap as solar zeroes out.

Demand-side context from market notices is limited for Victoria directly, but the QNI interconnector constraint (I-QN_550, invoked from 17:40 AEST) restricts NSW-QLD flows, which can tighten available import capacity into Victoria's supply chain indirectly. Weather for today's outlook shows a max of 24.2°C with 75% cloud cover and low solar potential (1.3 average), meaning rooftop solar suppression of midday demand will be reduced relative to clear-sky days, keeping daytime grid demand slightly elevated and supporting prices in the $30–70/MWh range through the business hours into the evening peak. Traders should note the $33/MWh forecast at 07:00 AEST gives way rapidly to $66/MWh at 07:30 AEST — that 30-minute window represents today's primary exposure point for unhedged load.
