Commodity Demand — VIC1: Friday 22 May 2026

Victoria's spot price sits at $47.93/MWh at 06:30 AEST with demand at 5,007 MW — a Saturday morning trough position that reflects a typical winter weekend profile. The price-demand relationship across the past 24 hours has been pronounced: when demand peaked at 7,519 MW around 08:15 AEST on Friday, prices reached $160/MWh, while the overnight nadir between 14:00–18:00 AEST saw demand fall below 4,600 MW and prices compress to single digits, including a brief negative print of -$1.51/MWh at 14:20 AEST. That 3,000 MW swing in demand produced a 160 $/MWh swing in price, confirming the market is operating in a steep part of the supply stack during morning and evening peaks.

Demand is now building from its overnight low, consistent with the Saturday morning warm-up cycle. At 8°C with 88% cloud cover and negligible solar potential, heating load is active and will drive demand upward through the morning. The generation mix at the most recent trading interval shows brown coal at 4,386 MW and wind at 1,664 MW, with solar contributing nothing and gas OCGT/CCGT offline — meaning incremental demand growth will draw on the same baseload stack that produced $100–160/MWh prices during Friday's morning peak. There is no gas peaking capacity currently in dispatch to buffer ramp events.

The forward forecast for 07:00 AEST (21:00 UTC) prices the next half-hour at $55.09/MWh, stepping up to a consensus range of $72–82/MWh by 07:30 AEST (21:30 UTC). This $15–25/MWh step-up aligns directly with demand expected to climb back through 6,000–7,000 MW as Saturday morning activity builds. Unlike a weekday profile, Saturday demand typically peaks earlier and lower — Friday's intraday peak above 7,200 MW is unlikely to be replicated today — but the absence of solar and compressed gas capacity means the 6,500–7,000 MW range remains a price-sensitive zone where $80–130/MWh outcomes are consistent with recent history.

One transmission factor warrants attention: Market Notice 144122 flags that the South Morang F2 500/330 kV transformer outage was scheduled through 17:00 AEST today, with constraint set V-SMTX_F_R active on VIC-NSW and VIC-SA interconnectors. This limits import/export flexibility on the northern boundary and reduces Victoria's ability to arbitrage interstate capacity during peak demand periods, adding upside price risk if demand climbs faster than the baseload stack can absorb without peaking plant.
