Once the TOP has developed a system restoration plan, what should be done with the plan?

The reason for periodically testing or simulating a system restoration plan is rooted in the need for preparedness and reliability in the electric power sector. Once a Transmission Operator (TOP) has developed a restoration plan, it is crucial to ensure that the plan is effective and that personnel are familiar with its execution. Regular testing or simulation helps identify any shortcomings or areas that may require adjustments, thereby enhancing the overall reliability of the grid.

Moreover, simulations allow staff to practice their roles within the plan, which is vital for their readiness in real emergency situations. Ensuring that the system restoration plan is not only theoretically sound but also practically applicable through regular drills can help prevent potential failures during actual events, ultimately contributing to a more resilient power system.

Other options focus on limited use or coordination that may not ensure the comprehensive readiness needed. For instance, using the plan only for the situation it was developed for does not capture changes in the operating environment or evolving challenges the system might face. Checking by system planning could be part of the evaluation process but does not encompass the active preparedness required. Lastly, coordinating only within the balancing authority may limit the effectiveness of the plan across wider operational contexts and fail to engage necessary stakeholders who may need to respond during a restoration effort.
