How often does a transmission owner need to report restoration information?

The frequency of reporting restoration information by a transmission owner is crucial for maintaining effective communication and ensuring the reliability of the grid. Reporting every 30 minutes or after 10 lines have been restored is designed to provide timely updates during restoration efforts, reflecting the dynamic nature of grid management. This requirement helps ensure that all stakeholders, including operators and other entities involved in transmission, are kept informed about the restoration progress in real time.

The rationale behind reporting every 30 minutes is that it allows for an assessment of the ongoing restoration efforts and enables necessary adjustments to be made based on the current situation. If significant progress is made, such as restoring multiple lines, this triggers an update. Such a threshold encourages timely and actionable communication, which is vital in emergency situations.

In contrast, reporting every hour after a restoration or every hour regardless of restoration may not offer sufficient granularity of information during critical or complex restoration scenarios. These options may lead to delays in responses to developing situations, whereas the chosen option emphasizes the importance of timely communication in managing and restoring the transmission network effectively.
