commodity demand vic — VIC1

Victoria's spot price sits at $122.29/MWh with demand at 5,694.91 MW at 16:30 AEST, continuing the morning ramp that began around 15:00 AEST (05:00 UTC) when demand climbed from ~4,760 MW and prices broke above $109/MWh. The price-demand relationship today is tight: each step up in demand through the morning peak corridor has translated directly into price escalation, with the 16:00–16:30 AEST window seeing demand surge through 5,600 MW and prices lock in above $120/MWh. Brown coal is carrying the baseload at 1,664 MW, gas OCGT is dispatching 542.29 MW to cover the gap, wind is contributing only 114.5 MW, and solar is at zero — leaving the grid heavily reliant on thermal plant at a carbon intensity of 0.9084 tCO2/MWh with just 14.6% renewable penetration.

The overnight-to-morning trajectory tells today's price story clearly. Demand troughed around 4,080–4,100 MW between 12:30–13:00 AEST (02:30–03:00 UTC) with prices hugging $56–60/MWh, then climbed steadily through the business-day ramp. The most price-sensitive period is now approaching: the history from this data set shows that demand in the 5,600–5,800 MW band consistently produces prices in the $120–172/MWh range, with spikes to $171.96/MWh recorded earlier in the day when demand reached similar levels. The current reading at 5,694.91 MW puts Victoria squarely in that volatile band, and with solar contributing nothing and wind at a negligible 114.5 MW, there is no renewable headroom to cap prices if demand pushes higher through the 17:00–19:00 AEST evening ramp.

The demand trajectory from the price history points to a likely evening peak above 6,000 MW — the data shows demand reaching 6,198–6,272 MW in the 02:00–03:30 UTC window (12:00–13:30 AEST, which maps to early afternoon). That afternoon peak drove sustained pricing of $130–161/MWh. Today's cooling demand is negligible (0) with heating demand modest at 0.5 and temperature at 17.5°C, so the evening peak will be demand-driven by lighting and cooking load rather than temperature stress — but the generation mix offers no buffer. Grid stress is scored at 74.4 with market conditions at 52.6, confirming the dispatch stack is stretched. Traders and flexibility operators should expect prices to remain above $120/MWh through the 17:00–20:00 AEST window, with spike risk if any thermal unit de-commits or demand surprises to the upside.
