What is the first step in performing System Restoration following a widespread blackout?

The first step in performing System Restoration following a widespread blackout involves identifying the affected area and performing a complete system assessment. This step is crucial because it allows operators to understand the extent of the outage, the number of customers affected, and the specific conditions of the transmission and generation facilities.

A complete system assessment provides vital information about the readiness of generation units, the status of substations, and any potential hazards or equipment failures that may have occurred during the blackout. This information is essential for making informed decisions on how to prioritize restoration efforts, mobilize resources effectively, and strategize on the safest and most efficient way to bring the system back online.

While notifying operators of the blackout situation, reestablishing communication, and deploying emergency response teams are all important components of the response process, these actions should occur after a thorough assessment of the situation is made. Understanding the scope of the issue lays the groundwork necessary for coordinating subsequent response activities.
