How often must Transmission Operators participate in the Reliability Coordinator's restoration drills and exercises?

Transmission Operators are required to participate in the Reliability Coordinator's restoration drills and exercises on an "as requested" basis. This means that while regular participation is encouraged for maintaining readiness and effective coordination in case of an emergency, the specific frequency can vary based on the Reliability Coordinator’s assessment of the needs.

This flexible approach allows for tailored participation that aligns with the operational requirements and the overall reliability strategy of the system. It recognizes that while training is essential, not every operator may need to engage in drills at a standardized frequency. Instead, these drills may be scheduled depending on the evolving conditions of the grid, changes in personnel, or updates in protocols.

This method ensures that operators remain proficient while also providing the Reliability Coordinator the ability to adapt the training to scenarios that are most relevant to current system dynamics. Regular communication and coordination help uphold the overall reliability of the transmission network.
