What is the time frame for the Reliability Coordinator to approve or disapprove a Transmission Owner's restoration plan?

The time frame for the Reliability Coordinator to approve or disapprove a Transmission Owner's restoration plan is 30 calendar days. This period allows the Reliability Coordinator to thoroughly review the proposed plan to ensure that it meets all necessary standards and regulations for reliability and safety.

This timeframe is critical because it balances the need for an expedient response from transmission owners in the event of a disturbance while still allowing adequate time for assessment and feedback. By establishing a clear window of 30 days, the NERC ensures that transmission restoration plans are appropriately scrutinized, helping to maintain the overall reliability of the electricity grid. This practice is part of a broader commitment to ensuring that all entities responsible for managing and restoring transmission resources cooperate effectively during both normal operations and disruptions. Maintaining this structure is vital for supporting operational excellence in power system reliability.
