Commodity Demand — NSW1: Saturday 25 July 2026
NSW demand sits at 7,846 MW as of 06:30 AEST, with spot price at $90.49/MWh — near the top of a range that has oscillated between $65-101/MWh over the past two hours as the region moves through the morning ramp. The 20:25 interval (06:25 local reference in trading terms) spiked to $101.10/MWh as demand touched 7,914 MW, confirming NSW's price curve is highly demand-elastic in this band: every ~150-200 MW of incremental load is adding $10-15/MWh, consistent with black coal (6,377 MW, the dominant source) running near its efficient dispatch ceiling and battery output (575 MW) absorbing the residual volatility.
The forecast trajectory points to a much sharper move ahead. AEMO's demand-linked price forecast shows spot climbing from $76.92/MWh at 06:30 to $108-123/MWh through the 07:00-09:30 window, then peaking at $134.86/MWh around 11:00 AEST before easing back to $80-85/MWh by early afternoon and settling near $65-70/MWh by 18:00. This morning peak is sharper than yesterday's equivalent window, where demand topped out at 10,155 MW (08:00 AEST) with prices holding in the $70-90/MWh band — today's forecast suggests tighter reserve margins or lower renewable contribution are pushing the marginal price higher for a similar demand shape.
Weather is a key demand-side driver: current temperature is 9.6°C with heating demand at 8.4 (elevated) and negligible wind (12.7 km/h, wind potential just 3.2%) and zero solar potential pre-dawn. Wind generation is currently only 551 MW and solar 15 MW, meaning the region is leaning heavily on thermal and battery dispatch to meet the morning ramp — a combination that explains why the price-demand relationship is steeper than typical shoulder-season mornings. Renewable penetration has fallen to 19.1% as of the last carbon reading (intensity 0.710 tCO2/MWh), down from 57% overnight when demand was low and wind/hydro covered a larger share.
No NSW-specific reserve or constraint notices are active today; the only live inter-regional issue is the Lismore 330kV circuit breaker outage affecting NSW-QLD transfer capacity, which could tighten import support if NSW demand runs hotter
