Commodity Demand — NSW1: Friday 31 July 2026
NSW spot price sits at $97.64/MWh at 06:30 AEST, with demand at 8,559 MW and climbing on the back of the winter morning ramp. This follows an overnight low of $7.85/MWh at 7,297 MW around 11:25 AEST (prior night) and a sharp evening peak last night that saw prices spike to $531.85/MWh as demand hit 11,433 MW around 07:30 AEST-equivalent. The current trajectory shows demand building from the 6,588 MW trough near 03:20 AEST through to present levels, tracking the typical morning load-up ahead of the day's first demand peak.
The demand-price relationship in NSW today is highly non-linear above roughly 10,500 MW. Through the overnight and shoulder periods (6,600-8,500 MW), prices hold in a tight $42-$110/MWh band, reflecting ample coal and hydro headroom. But once demand crosses into the 10,500-11,400 MW range, as seen in last night's evening peak, prices become extremely sensitive — a 900 MW increase in demand (from 10,555 MW to 11,433 MW) drove prices from $134/MWh to $531/MWh, indicating the region is dispatching increasingly expensive marginal capacity, likely gas peaking plant, at these higher load levels. Every 100-200 MW increment near this ceiling is adding tens of dollars per MWh.
AEMO's forecast points to two price-relevant demand windows today: a morning peak building toward 08:00-09:00 AEST with forecast prices of $91-$111/MWh, and continued moderation through midday and afternoon as prices ease to the $57-$65/MWh band by early afternoon into evening. Forecast prices stay comparatively subdued through to 18:00 AEST at $45.86/MWh, suggesting today's demand trajectory does not retest last night's 11,000+ MW peak-price event, consistent with mild forecast temperatures (8.6-15.5°C) limiting heating load. Traders should note the identified low-price windows overnight (00:30-01:30 AEST tomorrow at $28.85/MWh average, and 03:00-04:00 AEST at $34.21/MWh) offer the cheapest dispatch opportunities, though both carry medium-to-high risk ratings given thin overnight liquidity.
On the supply side, current generation mix shows black coal carrying 6,270 MW of the load, with hydro contributing 994 MW and wind at 734 MW — renewable penetration sits at 22.69% with carbon intensity at 0.679 tCO2/MWh, elevated versus the 24-hour range (0.469-0.685) due to low wind potential (1%) and negligible solar (0%) under current overcast, low-wind conditions. No active demand-side notices (load shedding, LOR declarations) affect NSW today; the only NSW-specific notice is the Directlink interconnector return to service at 14:30 AEST yesterday, which restores additional interregional transfer capacity relevant to price convergence with QLD.
