Planned or unplanned telemetering and control equipment outages must be reported if they last longer than how many minutes?

The requirement to report planned or unplanned telemetering and control equipment outages after a specific duration is crucial for maintaining system reliability and awareness among entities involved in grid management. Outages lasting longer than 30 minutes must be reported to ensure that all relevant parties are informed about potential impacts on grid operations and reliability.

This reporting requirement is in place so that reliability coordinators and operators can take necessary actions, such as adjusting operations or notifying other interconnected entities, to manage any risks associated with the outage. Timely information sharing is essential to maintain situational awareness and response readiness.

Other choices represent either too short or too long a duration for mandatory reporting, which would not effectively support operational reliability. By establishing 30 minutes as the threshold, it strikes a balance that promotes communication and coordination among grid participants while avoiding unnecessary alerts for very brief outages.
