Commodity Demand — NSW1: Monday 22 June 2026
NSW spot price sits at $140.73/MWh with demand at 9,233.8 MW at 06:25 AEST, continuing an evening ramp that began around 05:00 AEST from a mid-afternoon trough near 7,300–7,400 MW. The price-demand relationship today has been pronounced: as demand climbed from its overnight low around 6,800 MW (circa 12:50 AEST) through the morning peak, prices spiked repeatedly into the $175–$298.99/MWh range between 06:00 and 08:10 AEST when demand was pressing 9,800–10,760 MW. The mid-day softening to ~8,200–8,900 MW pulled prices back to the $85–$110/MWh band, confirming a tight demand-price relationship at the top of today's dispatch stack.
The forward curve points to a significantly more stressed morning tomorrow. Forecast prices remain elevated in the $131–$164/MWh range through 08:00–09:00 AEST tonight as demand continues its winter evening climb, before easing to $79–$84/MWh overnight. The standout signal is the 07:00–10:30 AEST tomorrow window, where the forecast sits at $275–$480/MWh across multiple half-hour periods, with $480.01/MWh forecast for 09:30, 10:00, and 10:30 AEST. This mirrors today's pattern where the morning demand ramp to above 10,000 MW — driven by cold temperatures (current 8.4°C, heating demand at 9.6 units) and the commercial/industrial load pickup — exhausted lower-cost dispatch capacity and forced expensive peakers to set price.
Two network notices shape today's capacity picture. The Newcastle–Eraring 330 kV line returned to service at 11:15 AEST this morning after a nine-day planned outage, restoring transfer capability into that corridor. Separately, a Murraylink planned outage invoked constraint set I-MURRAYLINK from 12:30 AEST, limiting SA-VIC-NSW import flexibility; this remains active and reduces the buffer available to NSW from western interconnector flows during tomorrow's morning peak. AEMO also issued a direction under s.116 of the National Electricity Law overnight to maintain secure operating conditions in NSW, cancelled at 08:50 AEST — confirming the grid was operationally tight during this morning's ramp.
The overnight demand trough presents the clearest cost opportunity: forecast prices drop to $42–$43/MWh between 14:00 and 16:00 AEST (00:00–02:00 local), with demand typically bottoming near 6,800–7,100 MW in that window based on today's profile. Flexible loads and battery charging should target that corridor. Any participant with exposure to the 07:00–10:30 AEST tomorrow window faces substantial price risk — the $480.01/MWh forecast across three consecutive half-hours reflects a market expecting tomorrow's morning demand ramp to replicate or exceed today's 10,700+ MW peak against constrained interconnector support.
