Commodity Demand — NSW1: Thursday 13 August 2026
NSW spot price sits at $94.83/MWh at 06:25 AEST with demand at 9,279 MW and climbing — up from an overnight trough near 5,600 MW around 02:00-04:00 AEST, when prices briefly went negative (as low as -$10.50/MWh) on soft demand and continued wind/hydro output. That morning ramp is textbook: demand rose roughly 3,700 MW between 03:00 and 08:00 AEST, and price followed in lockstep, jumping from around $50/MWh to a peak of $121/MWh at 07:45 AEST as demand pushed through 10,000 MW. The market is showing high price sensitivity in this 9,000-10,300 MW band — every 500 MW of demand growth through the morning shoulder has been adding roughly $10-20/MWh to spot.
Demand has since eased through the day, tracking down from a mid-morning high near 10,395 MW (08:55 AEST) to the current 9,279 MW, with price compressing accordingly from the $110-120/MWh band down to the mid-$90s. This afternoon easing reflects typical NSW winter demand shape — a firm morning peak, a softer midday trough, and a building evening peak as heating load returns with the 8.6°C temperature and minimal solar contribution (solar generation is just 1.4 MW currently, reflecting the 20:30 UTC timestamp equivalent to early evening AEST).
The forward curve points to a sharp overnight price collapse from current levels down to the $13-40/MWh band between 21:00 and 05:00 AEST, consistent with falling demand and a supply-heavy overnight mix (coal at 6,832 MW, battery at 841 MW, hydro at 931 MW versus wind of just 227 MW). But the standout signal is tomorrow's morning peak: forecast prices spike to $293-300/MWh between 10:00 and 12:30 AEST, well above today's $121/MWh high. This isn't demand-driven in isolation — it points to a tighter supply margin materialising tomorrow, and traders should treat the 09:30-12:30 window as the highest-risk period for price volatility. Low-carbon-intensity, low-price load-shifting windows exist overnight (1:00-6:00 AEST, averaging $13-42/MWh), offering up to $287/MWh in savings versus the peak for flexible load.
No demand-side constraints from today's market notices — the NSW-relevant items relate to a resolved Liddell-Tomago line outage (returned to service 10 August) and network constraint automation in Sydney's south (CA_SYDS_59839EB2, active since 3 August), neither of which currently caps NSW demand-side flexibility.
