Knoxville Utilities Board – KUB – was created by an amendment to the Knoxville City Charter in 1939. As an independent agency of the City of Knoxville, KUB provides electric, fiber, natural gas, water, and wastewater services to more than 501,000 customers in Knoxville and parts of seven surrounding counties. KUB leads the way with EVSE incentives in the area and with DCFC installations, and owns and operates Knoxville’s only public CNG station.
