Commodity Demand — VIC1: Saturday 23 May 2026

Victoria's spot price sits at $67.47/MWh against total demand of 4,741 MW at 06:30 AEST — a relatively modest load level consistent with a Sunday winter morning before households and commercial activity ramp up. The price-demand relationship across today's trading history is pronounced: demand peaked at 6,573 MW around 17:55 AEST with prices pushing to $99.89/MWh, then softened through the afternoon and evening as load retreated. The current demand reading is well below that intraday peak, yet prices remain elevated in the $65–70/MWh range, reflecting tight supply-side conditions rather than demand alone — brown coal is carrying 4,439 MW of the current 5,304 MW generation stack, with wind contributing 849 MW and solar at zero in these pre-dawn hours.

The demand trajectory through today's price history reveals a clear morning ramp dynamic. Load troughed near 4,578 MW around 04:15 AEST before climbing sharply through the pre-dawn period, with prices spiking to $87.91/MWh at 14:30 AEST as demand crossed 4,937 MW on its way up. The morning peak corridor between 17:00–19:00 AEST produced sustained prices in the $88–$100/MWh range as demand held above 6,400 MW — a load band where generator dispatch tightens materially in Victoria. Evening demand has since pulled back as expected on a Sunday, tracking the $64–$70/MWh range as load settles in the 4,400–4,750 MW corridor.

Forward price forecasts for the overnight and early morning intervals are materially softer. The 07:00 AEST interval (21:00 UTC) is forecast at $69.41/MWh, with the 08:00 AEST slot dropping to around $50–$54/MWh range and the 09:30–10:00 AEST window as low as $22–$34/MWh in some forecast runs — consistent with minimum system load conditions typical of a Sunday night through early morning before the winter morning ramp reasserts. The repeat of today's demand profile tomorrow will be shaped by 100% cloud cover, a maximum of 16.4°C, and negligible solar potential, meaning heating demand drives the morning ramp without any solar relief to suppress midday prices.

One active market notice warrants attention: AEMO has issued a direction in the SA region commencing from the interval ending 04:05 AEST on 24 May, with intervention pricing not applying. While this directly affects SA, any constraint on the Heywood interconnector (V-SA) under SA system conditions can influence Victorian export headroom and marginal pricing during the morning ramp window. Traders with exposure to VIC morning peak intervals should factor in potential interconnector flow constraints as demand climbs from its current 4,741 MW base toward the 6,000+ MW range expected between 17:00–19:30 AEST tonight.
