Regional Outlook — NSW1: Tuesday 9 June 2026

The NSW spot price sits at $71.75/MWh at 06:30 AEST with total demand at 8,359 MW and rising as the morning heating load builds. That current price represents a significant moderation from the sustained pressure seen through the earlier morning peak, where intervals repeatedly touched $111/MWh between 15:00 and 18:30 AEST and demand crested above 10,300 MW around 17:50–18:00 AEST. The 24-hour price profile has been characterised by two distinct cost bands: a soft overnight floor clustering around $61–$68/MWh through the small hours, and a persistent morning ramp that drove prices well above $100/MWh through the breakfast and early-business window. The current interval sits in the transitional zone between those regimes as demand climbs back toward that elevated morning range.

The generation mix at 06:25 AEST shows black coal supplying 5,393 MW, wind contributing 1,227 MW, hydro at 656 MW, solar at 111 MW, gas OCGT at 22 MW, and battery at a negligible 0.07 MW, with gas CCGT offline. Total renewable penetration sits at 26.92%, with wind carrying the bulk of that contribution given the low solar output expected on a winter morning with 23% cloud cover and zero solar potential. Carbon intensity is 0.6424 tCO2/MWh, which is elevated relative to the overnight low of approximately 0.507 tCO2/MWh recorded around 01:00 AEST when wind output was stronger relative to demand; the current reading reflects the higher coal dispatch share required to meet the climbing load.

Predispatch forecasts signal a sharp price escalation from 16:30 AEST onward. The curve lifts from $74.31/MWh at 07:00 AEST through $93/MWh by 08:00 AEST, then accelerates into the $120–$148/MWh range across the 15:30–22:00 AEST window, with the peak forecast at $148.16/MWh at 22:00 AEST. Notably, the 18:00–20:00 AEST band holds above $120/MWh throughout. This trajectory reflects winter evening demand loading against constrained transfer capacity — a pattern consistent with the grid stress score of 68.7 and low price stability score of 23.5. Flexibility-constrained buyers should note the $61/MWh floor window available overnight between 09:00–11:30 AEST before conditions tighten.

Two active market notices carry direct relevance to NSW today. AEMO issued an inter-regional transfer notice (MN 144217) following an unplanned outage of the Kerang–Koorangie 220 kV line in Victoria at 13:25 AEST, invoking constraint set V-KGKO which places equations on the VIC1–NSW1 interconnector. This constrains northbound transfer capacity from Victoria into NSW and is a material factor behind today's elevated price outlook — any reduction in Victorian import capability tightens NSW's supply stack precisely when evening demand peaks. Additionally, unit MULWASF1 was declared non-conforming (MN 144216) for a 25-minute window this morning at approximately 22:15 AEST, deviating by 15 MW under constraint
