Who is responsible for having a restoration plan for the system after a disturbance?

The responsibility for having a restoration plan for the system after a disturbance primarily lies with the Transmission Operator. This role involves overseeing the transmission of electrical power and ensuring the reliability and stability of the transmission network. The Transmission Operator must develop and implement plans and procedures that allow for the quick and efficient restoration of power following outages or disturbances.

When a disturbance occurs, the Transmission Operator coordinates with various entities to ensure that the system can be safely restored, minimizing downtime and ensuring that the power system is stable and reliable. They are tasked with understanding the entire system topology and anticipating issues that may arise during restoration, making their role critical in managing and executing restoration plans effectively.

While other roles like Reliability Coordinators and Generator Operators play significant parts in overall grid management and stability, the Transmission Operator specifically focuses on the operational aspect of restoration in the transmission network. The System Operator also has an important function but primarily supports day-to-day operations rather than focusing solely on restoration plans.
