Regional Outlook — NSW1: Wednesday 9 September 2026
NSW spot price sits at $119.02/MWh as of 06:30 AEST, sitting near the top of a steady overnight climb from sub-$65/MWh levels around midnight. Demand has risen sharply alongside price, up from a low near 5,290 MW around 12:00 AEST overnight to 8,418 MW currently, tracking the typical morning ramp. Prices spent the early hours in a low band ($0-$50/MWh) between 22:30 and 03:00 AEST as demand troughed, before climbing steadily through the $70s, $90s, and into triple digits as the morning peak builds — a pattern consistent with normal diurnal demand-driven pricing rather than any supply disruption.
Generation mix in the latest interval shows black coal supplying 5,395.7 MW, the dominant source, with hydro contributing 791.1 MW, wind at 1,068.5 MW, batteries delivering 354.6 MW, solar at 112.3 MW (reflecting early morning/low light conditions), and gas OCGT a minor 46.5 MW. Renewable penetration sits at 29.95%, having fallen from an overnight peak above 60% (reached around 02:00 AEST when demand was low and wind generation dominated) as coal ramps back up to meet rising morning demand. Carbon intensity currently reads 0.6151 tCO2/MWh, up from an overnight low of 0.3425 tCO2/MWh — this inverse relationship between renewable share and carbon intensity is typical for NSW's diurnal pattern.
Predispatch forecasts show prices easing through today's late morning into the low $40s-$50s/MWh range by 07:00-13:00 AEST (overnight into early morning target times), before climbing again into the $100-$118/MWh band around the 08:00-11:00 AEST window tomorrow as demand builds — consistent with the current trajectory. Prices are then forecast to moderate to the high $80s/MWh through the afternoon and evening period. Identified low-price windows for flexible load between 01:00-07:00 AEST tomorrow offer averages of $34-$45/MWh, representing $74-$110/MWh savings versus peak, with zero carbon intensity flagged in those windows given high renewable output relative to demand.
No active market notices directly affect NSW generation or network operation today — the reclassified contingency event on the Bayswater-Mt Piper 500kV lines from 5 September has since reverted to non-credible, and the Dapto-Kangaroo Valley 330kV line outage was completed and returned to service. Current NSW-specific interventions are absent; the active AEMO intervention and direction notices in the log relate to SA region voltage support (Torrens Island units) and are not impacting NSW dispatch. Weather today is cool (10.8°C, rising to 11-16.1°C range) with 89% cloud cover suppressing solar potential near zero currently, though outlook improves into the weekend with stronger solar potential (up to 22.8%) forecast from 13 September.
