Commodity Demand — NSW1: Wednesday 5 August 2026
NSW spot price sits at $207.51/MWh as of 06:30 AEST, with demand at 10,056 MW and climbing through the morning ramp. Overnight demand troughed near 6,400-6,700 MW between 01:30-03:00 AEST, coinciding with prices near zero and briefly negative (-$5.99/MWh at 01:50), before rising steadily as the cold morning heating load builds — current temperature is 6.8°C with heating demand at 11.2 and negligible solar potential (0%) at this hour.
The demand-price relationship this morning is tight and elastic. As demand climbed from 8,362 MW to over 11,300 MW between 06:00-08:35 AEST, prices jumped from ~$97/MWh to peaks above $230/MWh, with the volatile band between $169-$241/MWh persisting as generation stacked in black coal (6,701 MW) and battery (756 MW) to cover the ramp, while wind (428 MW) and solar (5 MW) contributed minimally given low wind potential (1.9%) and pre-dawn conditions. Demand has since eased back to 10,056 MW at 20:30 AEST equivalent trading interval, with price still elevated at $207.51/MWh reflecting continued tightness into the evening peak.
AEMO's forecast trajectory points to a sharp price escalation later today: forecast RRP jumps to $299.99/MWh by 21:00 AEST, peaking near $332.59/MWh by 22:00 AEST, before easing to the $50-90/MWh band overnight. A second, more pronounced peak is forecast for tomorrow's morning ramp, with prices forecast to spike to $299.99/MWh by 13:00 AEST and $291.90/MWh by 13:30 AEST — indicating the market is pricing in another steep demand ramp similar to today's pattern. Traders should note the constraint set CA_SYDS_59839EB2 active on the NSW1-QLD1 interconnector, which may limit import relief during these peak windows, tightening the demand-price relationship further. Grid stress score sits at 75.8, consistent with the observed price volatility across today's ramp periods.
