Which of the following actions is important for coordinating with Transmission Operators during system restoration?

Aligning on restoration timelines is essential when coordinating with Transmission Operators during system restoration because it ensures that all parties involved have a shared understanding of the sequence and timing for restoring power. This coordination is critical to effectively manage resources, prioritize actions, and minimize downtime. By agreeing on restoration timelines, operators can synchronize efforts, avoid conflicting actions, and work together to address the most urgent needs in the system.

While establishing communication lines, developing backup plans, and updating contact information are also important actions in the restoration process, they primarily focus on the logistics of communication, preparedness for contingencies, and ensuring that operators can reach each other in an emergency. The crucial element that ties these efforts together to ensure a smooth and efficient restoration process, however, lies in the synchronization of timelines, since this direct alignment helps to mitigate confusion and enhances the overall effectiveness of the restoration activities.
