Commodity Demand — VIC1: Sunday 14 June 2026

Victoria's spot price sits at $81.38/MWh with total demand at 6,368 MW as of 06:25 AEST, and the trajectory is upward. Demand has climbed sharply through the morning peak — from a trough near 4,170 MW around 01:10 AEST to the current level — tracking a clear correlation with price: every sustained demand push above 6,000 MW has anchored prices in the $70–$90/MWh band, while the overnight floor below 5,000 MW saw prices collapse to sub-$15/MWh, including a brief negative print at $-1.29/MWh around 03:50 AEST. The morning ramp has been steep, with demand lifting roughly 2,200 MW in under five hours on a cold winter Monday — ambient temperature is 5.5°C with a heating demand index of 12.5 — and prices have responded proportionally, breaking above $80/MWh as demand cleared 6,100 MW after 06:15 AEST.

The near-term outlook is for prices to escalate further before easing. Forecasts show the spot RRP lifting to $82.12/MWh at 07:00 AEST, then stepping up to $95.82/MWh by 07:30 AEST, and reaching a peak forecast of $101.09/MWh at 09:00 AEST. This price arc aligns with the typical weekday morning demand peak, where residential heating load and commercial ramp-up compress supply margins. The current generation mix — with brown coal at 4,641 MW, gas OCGT at 386 MW, and wind at 807 MW — shows peaking plant already in service, indicating the market is drawing on higher-cost capacity to meet the morning ramp. Solar contributes 0 MW at this hour, removing any intra-morning price relief until after 08:00 AEST when minimal irradiance begins.

The afternoon and evening present a markedly different picture. Forecasts show prices softening steadily from midday, dropping to $27–$30/MWh between 21:30–22:00 AEST as demand rolls off from its morning peak. More significantly, the forecast for 01:30–04:00 AEST tomorrow (Monday afternoon AEST equivalent for flexible load scheduling) shows prices in the $19–$42/MWh range, with the window between 00:30–04:00 AEST offering the lowest-cost exposure of the day. From 01:30 AEST tomorrow afternoon, forecasts turn negative — ranging from $-1.99/MWh to $-2.99/MWh between 01:30 and 04:00 AEST tomorrow — driven by forecast wind generation and suppressed midday demand. Demand-side managers and battery operators with flexibility to shift load out of the 06:00–10:00 AEST window stand to capture a spread exceeding $100/MWh against those negative afternoon periods.

The grid stress score of 83.6 out of 100 confirms the current supply-demand balance is tight. No VIC-specific generation outages or interconnector constraints are active that would artificially restrict supply in this period, so the price elevation is demand-driven rather than constraint-driven. The key risk to the morning price forecast is demand exceeding the current trajectory — a further 200–300 MW above the 07:30–
