commodity demand nsw — NSW1

NSW spot price sits at $71.40/MWh with total demand at 7,671 MW as of 06:30 AEST — well off today's peak but climbing through the early morning ramp. The demand trajectory across the past 24 hours tells a clear story: prices were anchored above $97/MWh when demand crested near 9,220 MW during the 18:00–19:00 AEST business peak, collapsed into negative territory (reaching -$8.92/MWh) through the 11:00–13:00 AEST overnight trough as demand fell to the 6,400–6,600 MW range, and are now rising again as the morning ramp accelerates. The price-demand relationship is tight: every sustained move above 8,500 MW has corresponded with prices above $80/MWh, while sub-6,700 MW demand has reliably cleared below $20/MWh or into negatives.

The forecast for the coming intervals points to a mid-morning peak period with prices expected in the $65–$77/MWh band, consistent with the 21:00 AEST interval forecasts that have converged on that range throughout the day. Current demand at 7,671 MW is tracking the typical autumn morning ramp — expect prices to push toward the $76–$97/MWh band as demand approaches the 8,500–9,000 MW range around 17:00–19:00 AEST. The generation mix at this interval is heavily weighted to black coal at 5,391 MW, with wind contributing 93 MW and solar 64 MW at 2.84% renewable penetration, leaving the grid exposed to thermal marginal cost pricing as demand rises.

A significant operational flag: AEMO has issued a sustained series of Manifestly Incorrect Inputs reviews under NER clause 3.9.2B covering intervals from approximately 03:30 through 15:45 AEST today. The 05:25 AEST interval has been confirmed with prices unchanged, but reviews remain active across more than a dozen subsequent intervals spanning the 03:30–15:45 AEST window. Traders should treat settled prices across those intervals as provisional — any repricing would alter the effective cost profile for positions dispatched through the overnight and early morning periods. The load window data signals that the optimal demand-shifting window is the 11:00–13:30 AEST overnight valley, where forecast prices range from -$8.92/MWh to approximately $10/MWh, representing savings of up to $143/MWh against current spot.
