Regional Outlook — NSW1: Monday 11 May 2026
The NSW spot price sits at $84.79/MWh with total demand at 7,621 MW as of 6:25 AEST. Tracking across today's price history, the market has followed a clear autumn weekday profile: an overnight trough hitting lows of $14.52/MWh around 3:05 AEST, a sustained morning peak band of $100–$121/MWh between roughly 5:30 and 9:30 AEST as demand climbed to an intraday high of 9,491 MW, then a gradual easing through the afternoon and evening back toward current levels. The 24-hour average across the available settlement history sits in the mid-$70s/MWh range, placing the current price modestly above that average as demand begins its evening build.
The generation mix at the 6:00 AEST trading interval is dominated by black coal at 5,297 MW, with hydro contributing 660 MW, wind at 236 MW, and solar at 77 MW. Gas-fired capacity — both CCGT and OCGT — is at zero output. Total renewable contribution stands at 15.52% of generation, consistent with overnight and morning carbon history data which showed renewables ranging from a low of 7.9% in the early hours to a peak near 20% during the previous evening. Carbon intensity sits at 0.7435 tCO2/MWh, a slight improvement from the overnight high of 0.8103 tCO2/MWh but reflecting the post-solar-generation period with coal carrying the baseload. Today's weather outlook — a partly cloudy day with a maximum of 20.8°C and average solar potential of 12.1 — points to a modest solar contribution lifting renewable penetration through the mid-morning period before fading into the afternoon.
Predispatch forecasts for the 7:00 AEST half-hour (21:00 UTC) are consistently clustering in the $88–$110/MWh range, with the most recent runs (from 6:01–6:31 AEST) settling around $88–$111/MWh, signalling prices are expected to firm as demand rises into the evening peak. The 7:30 AEST (21:30 UTC) forecasts are more elevated, with multiple runs pointing toward $108–$124/MWh — a clear predispatch signal of an evening ramp. The optimal load window data corroborates this: the cheapest periods today are flagged between 9:30 and 11:30 AEST UTC equivalent (roughly 1:30–3:30 AEST tomorrow morning), with prices as low as $9–$24/MWh rated "excellent" — well suited for flexible industrial loads or battery charging.
On market notices, the most operationally relevant item for NSW is the Wagga–Dinawan 330 kV double-circuit commissioning (Wagga–Dinawan 6L and 6J lines plus the Dinawan 330 kV A and B buses), completed on 9 May 2026 at 17:40 AEST. This augmentation adds transmission capacity in the southern NSW network and is now in service. The active inter-regional transfer limit notice for Directlink (constraint N-MBTE_1 on interconnector N-Q-MNSP1, in place since 5 May due to an unplanned outage of leg 3) remains active and is
