Commodity Demand — VIC1: Tuesday 19 May 2026

Victoria's spot price sits at $55.68/MWh with demand at 5,424 MW as of 06:25 AEST, well down from the session peak of 7,178 MW recorded at 08:05 AEST when prices were clearing in the $74–$80/MWh range. The demand-price relationship today is tracking closely to the typical morning ramp pattern: from overnight lows near 4,450 MW (15:30–17:30 AEST) where prices softened into the $35–$55/MWh range, demand has been climbing steadily through the post-sunset period, pulling prices back above $55/MWh. The overnight trough between roughly 14:05–14:10 AEST (00:05–00:10 UTC) saw negative and near-zero prices as supply surplus suppressed the market, with the low of -$12.10/MWh at 15:15 AEST the session floor.

The current generation mix has brown coal carrying 4,404 MW, wind contributing 1,689 MW, and battery storage dispatching 216 MW, with solar at zero given the 10°C overcast conditions and 100% cloud cover. Carbon intensity stands at 0.8516 tCO2/MWh with renewables at 30.2% of the mix. Critically, today's weather profile — maximum of 16.1°C with moderate cloud and low solar potential — constrains any midday demand reduction from rooftop PV that might otherwise soften the evening ramp. Heating demand at 7.6 units is active and will sustain elevated evening consumption.

The forecast price series for 07:00–08:30 AEST (21:00–21:30 UTC) points to $74.49/MWh and $80.79/MWh respectively from the most recent AEMO pre-dispatch run at 06:01 AEST, consistent with demand climbing back toward the 5,500–6,000 MW range as households reach peak evening heating load. Earlier pre-dispatch runs issued during the pre-dawn hours had the 21:00 AEST interval as high as $107/MWh before revising down as the trading day progressed — a signal that the market was uncertain about the evening trajectory. The $74–$81/MWh band now represents the settled consensus for the evening peak, roughly 35–45% above the current price.

For traders and demand-response managers, the key demand threshold to watch is the crossing above 6,000 MW, which earlier today consistently coincided with prices clearing above $80/MWh and occasionally spiking to $95–$113/MWh during the morning peak. Tonight's heating-driven demand build is tracking toward that same zone. AEMO's MT PASA notice confirms no low reserve conditions for Victoria, and no VIC-specific reserve or constraint notices are currently active, so the evening price escalation is expected to be demand-led and orderly rather than scarcity-driven. Load windows in the 09:30–10:30 AEST period (23:30–00:30 UTC) are forecast at $33–$35/MWh, offering the lowest-cost window for flexible loads before tomorrow's morning ramp.
