What type of communication loss could trigger the implementation of the Operating Plan for backup functionality?

The implementation of the Operating Plan for backup functionality primarily concerns disruptions that affect real-time system monitoring and control operations. Loss of total ICCP (Inter-Control Center Protocol) communication signifies a severe breakdown in the data exchange between control centers. This type of communication is vital for maintaining situational awareness, coordinating operations, and managing grid stability.

When total ICCP communication is lost, operators cannot receive essential data regarding system status, generation, load, and other critical metrics. This can lead to significant risks in operational integrity and reliability, triggering pre-defined protocols, such as the Operating Plan for backup functionality, to ensure that proper procedures are followed to mitigate potential risks and maintain safety.

While website downtime and email failures can interrupt communication and the sharing of information, they typically do not have the same immediate and critical impact on operational control as a total loss of ICCP communication. Data transmission issues might pose a concern, but unless they lead to a total loss of communication, they generally don't warrant the implementation of such a plan.
