Clinton Utilities Board (CUB) was founded in 1939. When the town acquired the system it served only 1,877 customers. Today CUB distributes electric service to more than 29,000 customers in six counties (Anderson, Campbell, Knox, Morgan, Roane and Union) and four municipalities (Clinton, Lake City, Norris and Oliver Springs). CUB purchases wholesale power from the Tennessee Valley Authority (TVA). CUB provides the necessary facilities to distribute electric service over approximately 1,400 miles of high voltage circuitry to our customers.

Clinton Utilities Board also provides water service to more than 6,000 customers and sewer services to more than 4,000 customers in the City of Clinton and the Claxton community.
