Commodity Demand — NSW1: Wednesday 3 June 2026

NSW spot price sits at $71.40/MWh with total demand at 8,197 MW as of 06:25 AEST, tracking the evening demand ramp that began around 05:00 AEST when the region emerged from an overnight trough near 6,400–6,500 MW. The price trajectory today has been tightly demand-correlated: the overnight period saw demand collapse to a low of approximately 6,400 MW between 12:30–13:30 AEST, with spot prices briefly turning negative (down to -$5.01/MWh at 14:20 AEST). As demand climbed through the morning, prices followed—peaking at $78.39/MWh at 09:50 AEST when demand sat near 9,900 MW, then easing through midday as demand fell back toward 8,100–8,500 MW before beginning the current evening ascent.

The day's demand profile shows a textbook winter double-hump: a morning peak of 10,103 MW reached at approximately 19:05 AEST, prices tracking between $43–$78/MWh through that window, followed by a midday trough and now a second evening ramp underway. Demand has risen roughly 1,600 MW in the past 90 minutes and continues to climb. Forecast prices for the 07:00–07:30 AEST slots (21:00–21:30 UTC) are locked in at $69.37/MWh and $75.31/MWh respectively, consistent with the current settlement price and reflecting market expectation of continued demand growth into the 8,500–9,000 MW range as residential heating loads intensify. Current temperature sits at 12.8°C with a heating demand index of 5.2, which supports that trajectory.

The $71–$77/MWh price band expected through the next hour represents a meaningful premium to the $50–$65/MWh range that prevailed during this morning's equivalent demand period, suggesting marginal generation costs are firmer on the evening stack. Wind is currently producing 2,035 MW and solar has essentially exited at 99 MW—the loss of solar as a price suppressor between the morning and evening peaks is a direct driver of the tighter supply margin now evident. Battery discharge at 224 MW is contributing but is insufficient to materially compress the price. With 73% cloud cover today and solar potential rated at zero for the current period, there is no intraday renewable upside to soften the ramp.

Demand-side market notices are not a material factor for NSW pricing today—all active contingency reclassifications affecting NSW (Bayswater–Mt Piper and Armidale–Dumaresq lines) have been cancelled, and no NSW-specific constraints remain invoked. The key price risk for the next two to three hours is the pace of the evening demand ramp; if demand approaches the 9,000–9,500 MW range seen this morning, prices have demonstrated willingness to test $75–$78/MWh. Forward load windows from 09:00 AEST tonight point to a sharp price retreat into the low-to-mid $20s/MWh as overnight demand unwinds below 7,000 MW.
