Commodity Demand — VIC1: Thursday 14 May 2026

Victoria's spot price sits at $54.69/MWh at 06:35 AEST with demand at 5,454 MW and rising — up from a low of around 4,235 MW in the early evening trough and climbing steadily through the post-sunset ramp. The demand trajectory over the past hour tells the key story: from 4,892 MW at 06:00 AEST to 5,454 MW at 06:35 AEST, a 562 MW lift in 35 minutes has pushed the price from $65.46/MWh to the current level. That rate of demand growth is consistent with Victoria's typical autumn evening ramp as space heating loads build in 10.5°C ambient conditions, and it is not yet near the day's peak demand band.

The price-demand relationship through today's data is sharp and instructive. Demand peaked at 6,652 MW around 18:10 AEST (08:10 UTC) with prices reaching $127.90/MWh, and an isolated spike to $192.78/MWh coincided with demand near 6,629 MW at 17:55 AEST — indicating tight supply margins at the top of the morning peak. By contrast, the midday trough, where demand fell to around 4,235–4,300 MW between 03:00–04:00 AEST (17:00–18:00 UTC), saw prices collapse to $13–$20/MWh, with wind generation at 2,257 MW and battery output at 307 MW covering a large share of load. The price elasticity across today's demand range has been steep: roughly every 500 MW of additional demand above 5,000 MW has corresponded to a $30–$50/MWh price step-up, with non-linear spikes emerging above 6,500 MW.

The evening ramp is the critical outlook driver. Demand is on an upward trajectory from 5,454 MW now and, based on today's morning peak pattern, is likely to approach 6,400–6,600 MW in the 07:00–09:00 AEST window. Forecast prices for the 07:00 AEST half-hour (21:00 UTC) are anchored around $63.88/MWh in the most recent AEMO pre-dispatch runs, with the 07:30 AEST period forecast at $63.88–$68.38/MWh — materially below this morning's equivalent peak outcome of $127–$131/MWh. That discount likely reflects tonight's strong wind output of 2,257 MW holding down marginal costs as demand climbs. Solar contributes zero at this hour and gas OCGT and CCGT are both offline, leaving wind, brown coal at 992 MW, and battery at 307 MW as the active supply stack.

Demand-side risk to the price outlook is moderate. No Victorian-specific market interventions or network constraints are active; the SA direction issued earlier today has been cancelled. Weather is benign for demand — tonight's forecast high of 21°C for Friday limits upside heating load risk against this morning's outcome. The most likely scenario is that the evening peak lands in the $65–$90/MWh range if wind holds and demand tracks seasonally normal. A wind output reduction or unexpected load surge above 6,600 MW would be the primary trigger for a price breakout toward the $100–$130/MWh range seen at
