A binding constraint (F_T+NIL_MG_RECL_R6) reached a marginal value of $20,290/MWh in the NEM, indicating a significant scarcity signal in the market. This high shadow price reflects a severe limitation in the system's ability to meet demand under the constraint conditions active at the time.
The binding constraint F_T+NIL_MG_RECL_R6 with a marginal value of $20,290 was the primary driver of this scarcity event. Additionally, the concurrent binding constraint T_BLINK_TV_NGZ exhibited an exceptionally high marginal value of $7,308,000, which substantially elevated overall system stress and contributed to the elevated marginal value of the primary constraint, indicating multiple simultaneous limitations on system capability.
