Question 1 · Application

A Transmission Operator adds new alarm points and new displays to the energy management system at its primary control center. Which part of its Operating Plan for backup functionality governs what happens next?

  1. A. The Operating Procedure for deciding when to move to backup
  2. B. The list of entities notified when operating locations change
  3. C. The Operating Process keeping backup and primary consistent
  4. D. The annual test demonstrating two continuous hours of backup use
Show the answer

Answer C The Operating Process keeping backup and primary consistent

R1 Part 1.3 requires an Operating Process for keeping the backup functionality consistent with the primary control center, which is what a change to primary displays and alarms triggers. The decision-authority procedure, the notification list and the annual test all deal with using or proving the backup, not with maintaining it in step.
