How often should a Reliability Coordinator review its System Restoration plan?

The correct answer is that a Reliability Coordinator should review its System Restoration plan within 13 months of the last review. This timeframe allows for periodic evaluation of the plan to ensure that it remains effective and reflects any changes in system conditions, operations, or technology.

Regular reviews within this schedule are essential for maintaining the reliability and effectiveness of the System Restoration plan. They ensure that any lessons learned from previous events, operational changes, and updates in regulatory requirements can be incorporated, leading to better preparedness for emergencies. This time frame strikes a balance between maintaining up-to-date procedures and the operational burdens of reviewing too frequently.

In contrast, other options such as every 6 months, every 2 years, and annually do not align with the established guidelines which emphasize a maximum review period of 13 months. Adhering to this specific timeline ensures that the plan is robust and aligned with the best practices in reliability coordination.
