A major binding constraint (T_BLINK_TV_NGZ) with an exceptionally high shadow price of $7.31/MWh occurred in TAS1 during the early morning period of 6 June 2026, coinciding with regional energy prices rising from $82.14 to $87.20/MWh between 06:45 and 07:00. The constraint subsequently relaxed as prices fell back to $77.66/MWh by 07:10.
The binding constraint T_BLINK_TV_NGZ with its extreme marginal value indicates a significant physical or operational limitation was actively constraining energy dispatch in Tasmania. The constraint's release coincided with a price decline and apparent reduction in wind generation (from 366 MW to 302 MW), suggesting that relief from the binding constraint may have enabled more efficient dispatch as the system state changed, though the data supports only that the constraint was active during the period of elevated prices and subsequently became less binding.
