NEM Overview: Friday 7 August 2026
Spot prices show a wide inter-regional spread this morning, with NSW1 at $109.96/MWh and QLD1 at $97.80/MWh well above VIC1 and SA1, both sitting at $0.01/MWh, and TAS1 at $0.08/MWh. WA1 (on its separate market) is at $85.15/MWh. Demand is highest in NSW1 at 8,459 MW and QLD1 at 6,257 MW, while VIC1 (5,341 MW), SA1 (1,377 MW) and TAS1 (1,092 MW) are running lighter. The NSW1/QLD1 premium over the southern states reflects tighter local conditions — NSW1 renewable penetration sits at just 17.4% with black coal supplying 5,663 MW of its mix, and QLD1 is similarly thermal-heavy at 16.4% renewables with 5,797 MW of black coal generation. VIC1-NSW1 flow is currently binding at 822 MW (export limit), pushing Victorian surplus generation north and helping explain the price gap.
Renewable penetration is diverging sharply by region. SA1 is at 97.2% renewables right now, running almost entirely on 1,556 MW of wind generation with negligible gas support. TAS1 sits at 83.8% renewables, driven by 595 MW of hydro output, and VIC1 is at 52.4%, with wind contributing 3,171 MW alongside 2,926 MW of brown coal. The NEM-wide renewable penetration score of 41.9% reflects this split between wind/hydro-rich southern regions and coal-dominated NSW1/QLD1. Grid stress is elevated at a score of 61.3, consistent with the binding T-V-MNSP1 (Basslink) flow of -422 MW and the binding VIC1-NSW1 interconnector, both indicating active transfer constraints managing the north-south price differential.
Weather today offers limited renewable upside in the south — VIC1, SA1 and TAS1 all show heavy cloud cover (82-100%) with low solar potential and modest wind potential, so the current north-south generation and price split is likely to persist through the day. QLD1 has clear skies and rising solar potential (30.4% average), which should support midday solar contribution there, though its wind resource remains thin. Cold minimum temperatures across all regions (4.8-11.7°C) are lifting heating demand generally, keeping thermal generation load elevated in NSW1 and QLD1.
On notices, traders should note the active non-conformance declaration for QLD1's MPP_1 unit (49 MW, 16:20-17:30 window on 7 August) and the ongoing reclassification of the Nebo SVC and transformer contingency in QLD1 to credible status, which remains in force with no invoked constraint sets but warrants monitoring given the region's current price premium. The NSW1 automated constraint set on the NSW1-QLD1 interconnector (invoked 4 August, still active) is also relevant given the -705 MW flow currently running from QLD1 into NSW1 (import direction) rather than typical southward transfer, worth watching if QLD1 tightness persists into peak demand periods.
