commodity demand nsw — NSW1

NSW spot price sits at $120/MWh with demand at 6,612 MW as of 06:30 AEST, marking the tail end of the evening price elevation that began around 06:00 AEST when prices broke above $100/MWh. Today's demand profile has followed a textbook autumn weekday pattern: a deep overnight trough bottoming near 3,785 MW around 13:00 AEST (when prices ran persistently negative, reaching as low as -$8.73/MWh), a sharp morning ramp through 06:15–07:30 AEST driving demand to a peak of 8,385 MW and prices tightly clustered at $100–$116/MWh, followed by a gradual mid-morning decline back through the 7,500–8,000 MW range where prices settled in the $80–$100/MWh corridor through the afternoon.

The price sensitivity to demand during this cycle is pronounced. The transition from the overnight negative-price period to positive territory occurred almost instantaneously once demand crossed approximately 6,300 MW around 15:55 AEST, with prices jumping from $23.67/MWh to $79/MWh within a single interval at 16:00 AEST. The evening ramp between 06:00 and 06:30 AEST saw prices accelerate from $79/MWh to $120/MWh as demand climbed from 6,455 MW to 7,189 MW — roughly $17/MWh of price uplift per 200 MW of demand addition. This tight demand-price relationship in the 6,500–7,200 MW range signals a steep marginal cost curve at current dispatch levels, with black coal at 5,279 MW and hydro at 461 MW providing the primary generation stack and no gas CCGT or OCGT online at this interval.

The forward price outlook points to a significant easing as demand retreats through the morning. Forecast RRP for the 07:00 AEST interval (21:00 UTC) has converged to $120/MWh across the most recent pre-dispatch runs, but the 07:30 AEST target carries a long-run forecast of $37.89/MWh — consistent with demand falling back below the ~6,500 MW threshold as the morning peak dissipates on a Sunday. Load window data confirms prices are forecast to return to negative territory between 08:00 and 14:30 AEST (22:00–04:30 UTC), deepening to -$25/MWh during the midday trough. Traders should note that AEMO has issued a large volume of "Prices Subject to Review" notices under NER clause 3.9.2B covering intervals from approximately 15:00 through 16:30 AEST this morning, flagging potential manifestly incorrect inputs across those pre-dawn periods — final settlement values for those intervals may differ from dispatch prices shown.

The dominant demand-side driver today is the Sunday low-activity profile combined with mild autumn temperatures (8.1°C, minimal cloud cover but zero solar generation at this pre-dawn hour). Heating demand is modest at 9.9 units, insufficient to sustain elevated demand through mid-morning once the breakfast peak clears. The practical implication: the $120/MWh print is transient, and absent any supply constraint or forecast deviation, NSW prices are on course to track back below zero by 08:30–09:
