A high-value binding constraint (F_S+SETB_L1) with a shadow price of $998/MWh has emerged in the NEM, indicating significant transmission congestion or network limitations are restricting power flow and inflating marginal costs. This constraint is substantially more severe than concurrent binding constraints, which carry marginal values below $5/MWh, suggesting a localised but acute bottleneck in the network.
The binding constraint F_S+SETB_L1 is the active network limitation driving the high marginal value, reflecting supply-demand imbalance or generation dispatch limitations within its affected region. The magnitude of this shadow price relative to other concurrent constraints indicates this particular network equation is the primary economic bottleneck, likely driven by transmission capacity limits or topology constraints that are preventing efficient power transfers during this period.
