When is it required to notify entities of defective or non-working interpersonal communication capabilities?

In the context of NERC requirements, the notification time frame for defective or non-working interpersonal communication capabilities is set at 30 minutes. This standard is crucial because effective communication is vital for maintaining reliability in the grid. When any communication capability fails, it can hinder the ability of operators and reliability coordinators to share critical information or respond to emergencies effectively.

The 30-minute requirement ensures that entities can promptly address communication issues before they escalate into more serious reliability concerns. This time frame balances the need for a quick response with the operational capability of the entities involved, helping to maintain the integrity and reliability of the electric grid. The specific duration is derived from established guidelines that prioritize swift communication recovery to facilitate coordination among reliability coordinators and other stakeholders.
