S.C. Code Ann. § 58-27-440

Whenever the service rendered by any electrical utility operating under an indeterminate permit shall be found inadequate by order of the Commission after hearing and such electrical utility shall fail to remedy the same after having been given a reasonable opportunity to do so, the indeterminate permit enjoyed by such electrical utility in respect to the service so found to be inadequate may with the consent of such municipality be declared revoked by the Commission upon such terms as shall be reasonable and just. But no order of the Commission revoking any such permit shall have any force and effect until a final determination of any proceeding brought to review the same.
