A binding constraint (F_T+LREG_0050) reached an exceptionally high shadow price of $232,000/MWh in the NEM, indicating severe physical or operational congestion. This represents a major market disruption with the constraint marginal value far exceeding typical wholesale electricity prices, suggesting critical system limitations are being enforced.
The data shows the binding constraint F_T+LREG_0050 was active across multiple dispatch intervals with a dominant spike to $232,000 followed by lower values ($56–$45/MWh) in subsequent periods, indicating an acute constraint breach that was subsequently relieved. Without generation mix, demand, or regional price data, the binding constraint marginal value alone indicates that supply-demand balance or network transfer capability hit a hard limit during the spike interval, forcing AEMO to adjust dispatch at extreme cost.
