Tenn. Code Ann. § 65-4-114: Service requirements

The commission has the power, after hearing, upon notice, by order in writing, to require every public utility, as defined in § 65-4-101 , to:

(1) Furnish safe, adequate, and proper service and to keep and maintain its property and equipment in such condition as to enable it to do so; and

(2) Establish, construct, maintain, and operate any reasonable extension of its existing facilities where, in the judgment of the commission, such extension is reasonable and practicable, and will furnish sufficient business to justify the construction, operation, and maintenance of the same, and when the financial condition of the public utility affected reasonably warrants the original expenditure required in making such extension, or to abandon any service when, in the judgment of the commission, the public welfare no longer requires the same.
