S.C. Code Ann. § 58-27-1260
If such electrical utility, except a municipality within its corporate limits, desires to exercise a right or privilege under a permit, consent or other authority which it contemplates securing but which has not as yet been granted to it, such electrical utility may apply to the Commission for an order preliminary to the issue of the certificate. The Commission may thereupon make an order declaring that it will thereafter, upon application, under such rules and regulations as it may prescribe, issue the desired certificate upon such terms and conditions as it may designate after such electrical utility has obtained the contemplated permit, consent or other authority. Upon the presentation to the Commission of evidence satisfactory to it that such permit, consent or other authority has been secured by such electrical utility the Commission shall thereupon issue such certificate.
