TUA serves 11,000 residential, commercial and industrial customers with low-cost, reliable power. Over 250 miles of distribution lines are maintained by the electrical department, which includes line workers and grounds workers, two engineering associates and an electric department manager. In addition to line maintenance, crews are also on call 24 hours a day for power outage emergencies.
TUA provides power through two main 161 kV substations, the most recent one being constructed by TUA staff and energized in March of 1997. Each main substation has the capacity of 75 MVA and each typically carries a winter peak load of 32 MW. The TUA distribution voltage is nominally 13 kV, three phase, 60 hertz.
TUA is a power distributor for the Tennessee Valley Authority, which has provided low-cost, reliable, public power to the customers of Tennessee and portions of surrounding states since 1933.
TVA provides regulatory oversight for your local power company’s rates and service practice policies.
If you have an issue or complaint that you have not been able to resolve with your local power company, TVA’s Complaint Resolution Process may be able to help.
There are three ways to begin the process:

Downed power lines are a serious emergency and should be reported immediately by calling Tullahoma Utilities Authority's 24-hour Emergency Hotline at 931-455-4515.
Never, under any circumstances, go near a downed power line or anything that is in contact with the line. It is very possible that the line could be energized, and there is absolutely no way for you to tell the difference. Remember, too, the line can become energized at any time.
If you are in a vehicle that hits a pole and wires fall on your vehicle, stay inside and ask someone to call 911 for fire and police rescue first, then TUA for assistance. Unless your life is threatened by severe injury or fire, you should remain in your car until an TUA representative tells you it is safe to leave. If you must leave, however, jump completely clear of the vehicle, never touching the vehicle and the ground at the same time. Land with your feet together and be careful to maintain your balance.
Again, to report an emergency such as a downed wire, an extremely low wire or one that is sparking, call TUA's 24-hour Emergency Line at 931-455-4515.
