Commodity Demand — NSW1: Saturday 22 August 2026
NSW spot price sits at $119.02/MWh at 06:30 AEST with demand at 7,294 MW, holding near the top of the price-setting band that's dominated trading since the overnight low. The relationship between demand and price today is tight and non-linear: demand troughed around 4,630-4,900 MW between 12:45pm and 3:00pm AEST overnight, driving prices into negative territory (as low as -$7.82/MWh) for an extended stretch, before the morning ramp saw demand climb from 5,500 MW to over 8,900 MW by mid-morning, pushing prices from near-zero up through $100/MWh and briefly spiking to $142.90/MWh at 8:15pm AEST as demand peaked near 8,890 MW.
The demand trajectory today shows a classic Sunday shape — an overnight trough, a moderate morning ramp, and a broad midday plateau rather than a sharp evening peak. Demand has been easing back from the ~8,890 MW high, tracking down through the 7,000-7,300 MW band through the afternoon and evening, with price responding accordingly, oscillating between $95-$122/MWh as generators adjust to the gentler demand slope. Forecasts for the remainder of today point to further softening: AEMO's price forecast has RRP falling to $69.99/MWh by 9:30am, then collapsing through single digits and into negative territory ($-6.60/MWh) between 1pm and 2pm AEST as demand drops toward typical Sunday midday lows, before recovering only modestly into the evening (forecast $57-97/MWh band through the afternoon-evening window).
Price sensitivity to demand is elevated at the margin — each 500-1,000 MW swing in demand is triggering $30-60/MWh price moves, consistent with a supply stack where black coal (5,867 MW) and hydro (857 MW) are covering the bulk of load and gas peaking units are only marginally engaged (OCGT at 34.5 MW, CCGT at zero). This leaves limited fast-response headroom to smooth price volatility as demand ramps. No specific NSW demand-side notices are in force today; the active market notices relate to SA voltage-support interventions and network outages in NSW (Vineyard-Sydney West, Lismore-Koolkhan lines) that affect transfer capability rather than NSW load directly. Given the forecast demand trough around 1-2pm AEST, load-shifting opportunities are strongest in that window, with the overnight low-price window (1am-5am AEST tomorrow) also flagged as low-risk for flexible load at $-5 to $1/MWh.
