NEM Overview: Monday 3 August 2026

NEM spot prices are running in a tight $88-103/MWh band across the eastern regions this morning, with WA1 the outlier at $130.15/MWh. SA1 leads the eastern states at $102.66/MWh, followed by QLD1 ($97.83/MWh), NSW1 ($97.64/MWh), VIC1 ($92.52/MWh) and TAS1 the softest at $88.24/MWh. Demand sits at 9,510 MW in NSW1, 7,111 MW in QLD1, 6,662 MW in VIC1, 1,559 MW in SA1 and 1,234 MW in TAS1. Cold overnight temperatures (4-9°C across all regions) are driving heating demand, with NSW1 and TAS1 showing the highest heating load at 11.2 and 13.9 respectively, while solar and wind potential remain minimal ahead of sunrise.

Generation mix reflects the early-morning period, with black coal dominant in NSW1 (6,750 MW) and QLD1 (5,880 MW), and brown coal at 4,566 MW in VIC1. Wind is a significant contributor in VIC1 (2,371 MW) and NSW1 (827 MW), while batteries are active across all mainland regions — NSW1 batteries are generating 937 MW, QLD1 651 MW. TAS1 hydro output of 1,167 MW underpins that region's renewable penetration at 90.4%, the standout figure nationally. VIC1 sits at 36.7% renewable, SA1 at 30.6%, NSW1 at 26.4% and QLD1 the lowest at 16.0%. Carbon intensity tracks accordingly: TAS1 at 0.062 tCO2/MWh, SA1 at 0.399, NSW1 at 0.647, QLD1 at 0.736 and VIC1 at 0.762. The NEM-wide renewable penetration score sits at 41.7%, with the grid stress score elevated at 73.5, reflecting tight overnight conditions and cold-weather demand.

Interconnector flows show V-SA exporting 525 MW from Victoria into South Australia and VIC1-NSW1 flowing 255 MW northward, with none of the monitored links currently binding. NSW1 carries an active credible contingency reclassification on the Bayswater-Mt Piper 500kV lines due to lightning activity, cancelled and reinstated twice in the past 24 hours — worth monitoring given recurring storm cells in the area. TAS1 has seen a string of similar lightning-driven reclassifications on the Norwood-Scottsdale, Palmerston-Hadspen, Sheffield-George Town, Ulverstone-Emu Bay and Burnie-Port Latta-Smithton lines, all since cancelled, indicating the system is managing transient weather risk rather than sustained network constraints. SA1's prior AEMO intervention (Torrens Island directions for voltage support) was cancelled Sunday, and no active interventions remain in place this morning.

Through the day, expect prices to soften in NSW1, VIC1 and QLD1 as solar ramps into the low-to-mid 20% potential range by midday, with SA1 solar potential negligible under heavy cloud cover (96%). TAS1 hydro will continue to anchor low-carbon supply. WA1's elevated price warrants attention for traders exposed to that market, though it operates outside the interconnected NEM.
