Commodity Demand — VIC1: Sunday 30 August 2026
Victoria's spot price sits at $95.69/MWh as at 06:30 AEST, with demand at 6,022 MW and climbing sharply through the morning ramp. Demand has risen from an overnight trough near 2,900-3,100 MW (03:00-05:00 AEST) to over 6,000 MW in the space of three hours, and price has followed almost in lockstep — a clear demonstration of VIC1's steep supply curve at this time of year. Through the overnight low-demand window, prices spent extended periods negative (as low as -$20/MWh around 04:00 AEST) as minimum system load conditions combined with must-run generation pushed the market into oversupply. That relationship inverted quickly once demand cleared roughly 4,400 MW, with price jumping from single digits to above $80/MWh within 30 minutes as brown coal and gas peaking plant were recalled to meet the ramp.
The generation mix at 20:30 UTC (06:30 AEST) shows brown coal carrying 4,290 MW of the load, with battery storage contributing 687 MW and gas OCGT a further 398 MW — solar is still at zero given the early hour and heavy 95% cloud cover, while wind sits low at 190 MW. Renewable penetration has fallen to 16.5% as the overnight wind and battery contribution is diluted by the demand ramp, and carbon intensity has correspondingly risen to 0.978 tCO2/MWh, up from a low of 0.777 tCO2/MWh at 06:00 AEST.
AEMO's forecast trajectory points to a firming price profile through the morning peak, with forecast RRP climbing to $144.48/MWh by 08:00 AEST and holding above $140/MWh through to 10:00 AEST before easing into the afternoon. This aligns with the seasonal load pattern — cool 9.9°C conditions this morning are driving heating demand (8.1 on the index), and the demand curve is expected to plateau through mid-morning trade before the typical shoulder-season afternoon relief, with forecast prices falling below $30/MWh by 14:30 AEST and into negative single digits again overnight. Traders should note the extreme intraday volatility bands VIC1 is exhibiting — a swing from -$20/MWh to +$144/MWh forecast within a 12-hour window — reinforcing that minimum demand periods carry oversupply risk while the morning and evening ramps remain tight for dispatchable capacity.
No VIC-specific demand-side notices are active today; the SA region's recurring Minimum System Load advisories (MSL1 forecast again for 31 August, 13:00-14:00 AEST) don't directly affect Victorian demand but signal continued low-demand risk across the wider NEM that can pressure interconnector flows and dampen VIC pricing during those windows.
