A major binding constraint (T_BLINK_TV_NGZ) with an exceptionally high shadow price of $8.352 million/MWh became active in TAS1 during the settlement periods ending 23:20–00:00 on 5–6 July 2026. Prices remained relatively stable around $88/MWh until a sharp dip to $51/MWh at 23:55, followed by recovery to $85/MWh at midnight, suggesting the constraint was significantly limiting dispatch flexibility during this period.
The binding constraint T_BLINK_TV_NGZ, with its exceptionally high marginal value, indicates severe restriction on power flows that became the primary price-setter for the region. The generation mix was dominated by hydro output (ranging 1,150–1,684 MW across the snapshots) with modest wind contribution (75–82 MW), leaving limited flexibility to relieve the constraint through dispatch adjustment, thereby driving the extreme shadow price.
