We Will Prove Our Worth Every Day!


Call LUB immediately at (423) 562-3316 or 1-800-352-1340 if:

  • Reporting EmergenciesThe electric power is out, a power line is down, or there's another electrical emergency
  • You have no water or a water quality problem
  • Your wastewater (sewage) backs up

(Don't call 911. That line is reserved only for police, fire, and medical emergencies.)


  • Severe weather (snowstorms, thunderstorms, wind, ice storms, etc.)
  • Animals (such as birds or squirrels interfering with poles and lines)
  • Overloaded lines
  • Blown transformers
  • Vehicles striking and breaking utility poles
  • Problems at substations


  • Restore power at main substations
    • A problem within a substation or with the transmission line going to the substation would cause all of the substation to be out of service.
  • Repair main distribution feeder lines
    • Each main feeder circuit or line serves a section of LUB customers from the substation.  There can be more than a thousand customers on a main feeder circuit.
  • Repair three-phase lines
  • Repair single-phase lines
    • These serve smaller groups of customers off a main feeder.  They can be isolated from the main feeder by disconnects, fuses and other sectionalizing equipment.
  • Individual services
    • These problems usually affect individual services. 

Substation and transmission lines are first priority. If there are no problems at the substation, LUB employees will work to repair damage to the main feeder lines. This action restores power to a large number of people as quickly as possible. If there are no other main feeder line problems, LUB crews then begin repairing problems on tap lines, which may serve as many as 100 customers. After these lines have been repaired, crews will begin repairing individual services.


  • Locate candles, kerosene lamps, or flashlights to help you see if the power goes off at night. You will be able to see what you are doing, and circumstances seem less threatening.
  • Look to see if your neighbors' lights are off. If the neighbors' lights are not off, the problem may be confined to your home.
  • Check fuses and breakers. If there is a problem with the fuses or breakers, again, the problem may be confined to your home.
  • Turn off all electrical appliances that were on, especially heat pumps, air-conditioners, and electric heating. This will prevent the system from overloading once the power is restored.
  • Call LUB to inform them of the power outage. Give your address, how long the power has been off, or if there are lines down.
