Commodity Demand — NSW1 — Saturday 9 May 2026

NSW spot price sits at $118.53/MWh with demand at 7,040 MW as of 06:35 AEST, placing the market firmly in the elevated-price band that has characterised the evening period since approximately 19:50 AEST. Today's demand profile has traced a textbook autumn weekday shape: a deep overnight trough bottoming near 4,800 MW between 11:40 and 13:00 AEST — where prices briefly turned negative (as low as -$3.83/MWh) — before a sharp morning ramp that pushed demand through 8,700 MW by 18:40 AEST and prices solidly above $100/MWh. Demand has since eased from that peak but remains at a level where the market is pricing marginal supply firmly above $100/MWh. The price-to-demand relationship is notably sensitive in the $97–$122/MWh corridor: every interval above roughly 6,800 MW today has cleared above $95/MWh, confirming that the current supply stack has limited low-cost headroom once the grid moves beyond mid-evening load levels.

The demand trajectory through the balance of tonight points to further easing. Forecast prices for the 07:00 AEST half-hour (21:00 UTC) have been revised upward across successive AEMO STPASA runs — from around $87–$92/MWh earlier in the day to $120/MWh in the most recent forecast issued at 06:01 AEST — suggesting dispatchers are carrying less comfortable margins than morning forecasts implied, consistent with demand sitting above 7,000 MW at this hour. The 07:30 AEST (21:30 UTC) interval is forecast at $92/MWh, indicating the market expects demand to ease toward the 6,500–6,800 MW range over the next hour, which should bring prices back below $100/MWh. Load windows confirm overnight prices from 08:30 AEST (22:30 UTC) onward are expected to fall sharply into the $35–$40/MWh range, with the deepest valley around 09:00–11:30 AEST (23:00–01:30 UTC) where forecast clearing prices drop to $10–$25/MWh as Sunday overnight demand sinks below 5,000 MW.

One market notice is directly relevant to NSW demand-side conditions today: AEMO commissioned the Wagga–Dinawan 330 kV double circuit (6L and 6J lines plus the Dinawan 330 kV buses) at 17:40 AEST under Market Notice 144069. This network augmentation improves transfer capability within the western NSW transmission corridor and marginally increases the dispatchable supply accessible to the Sydney load centre during evening peak, providing a modest constraint-relief factor that limits upside price risk relative to what the same demand level might have cost before commissioning. No reserve notices or directions are active in NSW. The Armidale No.3 transformer outage (Market Notice 144064) that constrained QNI earlier in the day has no active constraint set remaining, leaving interconnector headroom broadly normal for this hour.

For demand-side managers and flexible load operators, the price signal today is clear: the $8–$25/MWh trough between approximately 09:00 and 11:30 AEST represents the optimal load window on a day where evening prices are running $90–$120/
