How long can a BA use imported power in an emergency without submitting a request for Arranged Interchange?

A Balancing Authority (BA) is permitted to utilize imported power in an emergency situation for a duration of up to 60 minutes without the necessity of submitting a request for Arranged Interchange. This provision allows BAs to quickly respond to unforeseen events or contingencies—like sudden outages or significant load changes—by importing power to stabilize their system without the immediate bureaucratic requirement of formal arrangements. The allowance for using imported power for this time frame helps ensure reliability and continuity of service in critical situations, while still maintaining a framework that necessitates communication and coordination beyond that time period.
