Knoxville Utilities Board was created by an amendment to the Knoxville City Charter in 1939. As an independent agency of the City of Knoxville, KUB provides electric, gas, water, and wastewater services to more than 445,000 customers in Knoxville and parts of seven surrounding counties. KUB believes utility service should be so reliable that customers can take it for granted, and we work hard to maintain such reliability.
