Regional Outlook — NSW1: Sunday 6 September 2026
**New South Wales spot price sits at $90.01/MWh as of 06:30 AEST, tracking near the middle of an overnight range that swung from $113.28/MWh at 18:00 down to sub-$5/MWh troughs between 09:00-15:00 AEST as overnight demand collapsed to 3,379 MW.** Demand has since rebuilt to 7,524 MW heading into the Monday morning ramp, and the price has climbed from single digits before dawn to the low-$100s during the 17:00-18:30 AEST window before easing back to $90.01/MWh. This mirrors typical morning demand build, with intraday volatility exceeding $110/MWh peak-to-trough over the past 24 hours.
Generation mix at 06:25 AEST is dominated by black coal at 5,400 MW, comfortably the largest contributor. Behind it, hydro is supplying 501 MW, battery output sits at 355 MW, wind at 283 MW, gas OCGT contributing a modest 43 MW, solar at just 23 MW (reflecting pre-dawn conditions), and gas CCGT offline. Renewable penetration reads 17.6%, well down from the 66% peak recorded around 23:30-00:00 AEST overnight when wind and hydro dominated a low-demand system. Carbon intensity has risen in step, now at 0.7236 tCO2/MWh, up from an overnight low of 0.2948 tCO2/MWh — a pattern consistent with coal's rising share as solar has not yet ramped and wind output remains modest against today's forecast average wind potential of 6.9%.
Predispatch forecasts show prices firming through the morning peak, reaching $111.98/MWh by 07:30 AEST and climbing further to $122.86/MWh at 09:00 AEST and $122.79/MWh at 09:30 AEST — the highest points in the current forecast window — before easing to the $100-114/MWh band through late morning. Afternoon forecasts ease further, with prices moderating to $83-85/MWh by 14:30-15:00 AEST and settling near $71-76/MWh through the 16:00-18:00 AEST period as solar generation ramps under today's forecast 27.9% average solar potential and milder 20.7°C max temperature keeps cooling demand low.
On notices, NSW-specific items are limited to network matters: the Dapto-Kangaroo Valley No. 18 330kV line outage was completed and returned to service on 5 September, and a brief NSW1 contingency reclassification affecting the Bayswater-Mt Piper 500kV lines due to lightning was cancelled the same day with no constraint sets currently invoked. No active NSW1 non-conformance or intervention events are on the board this morning — the recent non-conformance and intervention notices cluster in SA1 and VIC1, not NSW1. Grid stress score sits at 61.2 and market conditions at 48.2, consistent with today's price volatility profile rather than any acute NSW-specific constraint.
