S.C. Code Ann. § 58-27-1290: Abandonment of service.

No electrical utility shall abandon all or any portion of its service to the public, except for ordinary discontinuance of service for nonpayment of undisputed charges in the usual course of business, unless written application is first made to the commission for the issuance of a certificate authorizing the abandonment, and until the commission in its discretion issues a certificate after a public hearing of all parties appearing to the commission to be interested. The electrical utility also must serve a copy of its application upon the Office of Regulatory Staff.

In any such case, any interested party shall have the right within fifteen days after the final order of the commission to apply to the Supreme Court for a review thereof, and in such case, no such abandonment shall be permitted until the appeal is heard and the Supreme Court by order permits the abandonment.
