Service restoration depends on the magnitude and duration of the storm causing the service interruptions.
 
UI’s general sequence of service restoration is:

First Priority

• Public safety requires the de-energizing or cutting down of downed line, primary voltage distribution lines.
• Restoration of service to previously designated public emergency service institutions such as major hospitals, evacuation centers, as prioritized by municipal officials.

Second Priority

• Service restoration to a maximum number of customers in a minimum amount of time using available work forces. This usually involves the removal of trees and limbs, the bypassing of some damaged equipment and the re-energizing of primary voltage distribution lines.

Third Priority

• The repair and restoration of equipment and lines serving small groups of customers.

Fourth Priority

• Although the restoration of service lines to individual homes or buildings is designated as Priority 4, they will in most cases be done at the same time as other restoration work designated with a higher priority. This is accomplished by using crews not normally associated with distribution restoration work.
