Commodity Demand — NSW1: Sunday 23 August 2026
NSW demand sits at 8,272 MW as of 06:25 AEST, up sharply from an overnight trough near 5,420 MW at 01:30 and climbing fast through the morning ramp. Spot price is $71.40/MWh, having already touched $90.49/MWh at 10:20 AEST-equivalent overnight-trading timestamps as demand crossed 9,150 MW. The data shows a tight relationship between demand and price above the 8,000 MW mark: every 100 MW of load added through the 7,000-9,200 MW band has been adding roughly $3-5/MWh, with the steepest gradient between 7,900 MW and 9,000 MW, where price jumped from $65/MWh to a peak above $90/MWh in under 90 minutes. Below 7,000 MW overnight, price was largely decoupled from demand and hovered in single digits to low $40s/MWh, confirming baseload plant is comfortably covering the trough.
The forecast trajectory points to a much sharper price response later today. AEMO's forward curve has prices easing to $57/MWh by 08:00 AEST and falling into negative territory ($-2/MWh) around 13:00-14:00 AEST as rooftop and grid solar ramp — consistent with today's forecast solar potential of 25.3% and light cloud cover (19%). But the afternoon-evening transition is the key risk window: forecast RRP climbs from $42.80/MWh at 00:30 AEST tomorrow-equivalent back up to $104.28/MWh by 18:30 AEST and $109.98/MWh by 19:30 AEST as solar drops away and evening demand ramps. This mirrors last night's pattern, where NSW demand climbed from 6,700 MW at 17:00 AEST to 8,270 MW by 20:25 AEST, pushing price from $57/MWh to $71/MWh over that window.
Current generation mix is black coal-dominated (4,882 MW), with wind contributing 843 MW and hydro 325 MW; renewable penetration sits at 21.3% and carbon intensity at 0.69 tCO2/MWh, reflecting the low-solar, moderate-wind conditions typical of this time of day. Today's mild temperature outlook (11.9-20.4°C) limits heating and cooling demand pull, so the demand curve is following typical midweek diurnal shape rather than being weather-driven. No NSW-specific demand-side notices are active; the SA voltage-control directions and VIC/TAS contingency reclassifications do not directly affect NSW load or pricing today. Traders should watch the 17:00-20:00 AEST window closely — that's where the forecast curve shows the largest, and least certain, price escalation of the day.
