The Transmission Service Provider shall approve or deny each on-time Arranged Interchange or emergency Arranged Interchange that it receives and shall do so prior to the expiration _____ if submitted greater than one hour after the start time.

• A. 2 hours
• B. 30 minutes
• C. 4 hours
• D. 24 hours

Answer: (A)

The requirement focuses on timely action for Arranged Interchanges to keep real-time scheduling aligned. When a Transmission Service Provider receives an on-time Arranged Interchange or an emergency Arranged Interchange, it must approve or deny it within a defined window. If the interchange is submitted more than an hour after the start time, the deadline is two hours after the start time. In other words, the TSP must complete the decision before the interchange expires two hours after the start, so late submissions don’t linger unresolved and affect reliability and settlements. The other timeframes would either be impractical for timely scheduling or allow too long a delay for late submissions.
