In case of facility outages, how soon after should a notification be given for facilities rated 345 kV and below after taking them out?

For facilities rated 345 kV and below, prompt notifications are essential to maintain the reliability of the electric grid. The requirement is to provide notice within a specified timeframe after a facility has been taken out of service. This immediate communication helps ensure that operators and stakeholders can respond quickly to potential reliability issues and adjust operations accordingly.

The correct timeframe of 15 minutes is crucial, especially in situations that could affect system stability. In a dynamic environment like electric transmission, delays in communication can lead to larger problems, including the inability to manage load demands or adequately implement contingency plans. Therefore, the requirement for a 15-minute notification reflects the urgency and critical nature of keeping all operational participants informed so that they can take necessary actions to safeguard the transmission system.
