What is the maximum duration for reporting unplanned telemetering outages?

The maximum duration for reporting unplanned telemetering outages is 30 minutes. This requirement is rooted in the need for real-time monitoring and communication in the electric grid, which is critical for maintaining reliability. When telemetering systems experience outages, they can severely hinder the ability of control centers to receive important data regarding the status and performance of the grid. Prompt reporting—within 30 minutes—allows operators to take the necessary corrective actions swiftly, thereby minimizing risks to grid stability and ensuring that all stakeholders have timely information to make informed decisions.

In the context of reliability standards, the 30-minute reporting window ensures that issues are escalated quickly, facilitating a coordinated response to restore normal operations. This time frame reflects the urgency with which grid operators must act in the event of telemetry outages, emphasizing the importance of maintaining a continuous flow of data in the monitoring and control of electricity transmission.
