The NEM ran a split overnight session: Victoria and South Australia touched floor prices repeatedly, with VIC1 sitting at $8.15/MWh and SA1 at $8.45/MWh at 06:35 AEST as morning demand ramped from deep overnight troughs. Tasmania held the highest NEM average at $100/MWh, tracking a steady climb from a 01:45 AEST trough near 843 MW. Queensland entered the morning peak at $70.96/MWh with demand at 6,741 MW and rising. Watch the QNI interconnector today — it is binding at its import limit of –523 MW, creating a material north–south price spread that is shaping NSW1 and QLD1 dispatch through the morning ramp.
Tasmania reached 100% renewable generation during the 09:35–10:00 AEST window, with hydro contributing approximately 1,255 MW combined and wind adding around 117 MW. Notably, spot prices remained orderly at $106.26/MWh through the period — a fully renewable operating state without price volatility. TAS1 posted the NEM's highest 24-hour average at $100/MWh and a session max of $140/MWh, reflecting Tasmania's structural supply tightness relative to southern mainland regions.
WA1 posted the highest average price across all six regions at $149/MWh, with a session maximum of $157/MWh — a comparatively narrow spread suggesting sustained elevated conditions rather than a single spike event. The WEM continues to trade materially above NEM mainland averages. No additional WEM event data is available for this session; the pricing level alone warrants attention for WA-based energy managers.
