The electric power tax is imposed upon persons in the business of selling electric power. It is imposed at either the wholesale level or the retail level depending on who is selling the electric power and whether the electric power tax had been previously paid on the electric power. The tax is imposed based on the number of kilowatt hours of electric power sold. See Code Section 12-23-10.

Code Section 12-23-20 provides the following exemptions from the electric power tax:

1. Electric power manufactured or generated in another state and brought into SC until such power has lost its interstate character and immunities;
2. Electric power or energy generated in SC by plants constructed after May 1, 1951 and exported to another state;
3. any person owning and operating an electric manufacturing or generating plant of ten horsepower or less;
4. any industrial plant manufacturing or generating power for its own use or for use upon its own premises by its bona fide operatives or employees, but the tax shall be paid upon so much thereof as may be sold to other than its employees;
5. A municipality manufacturing or generating electricity for the use of its customers; or
6. Electric power used in manufacturing or generating hydroelectric power and steam electric power, and electric power used in the operation of such electric power manufacturing or generating plants and auxiliary machinery and equipment necessary thereto; provided, that all such power that is used for generation of power, which is to be exempt from taxation, shall be exempt only if it is metered; nor shall they apply:
7. When the entire capital stock of a corporation owning and operating a plant manufacturing or generating electric power is owned by an industrial corporation, to such power as may be furnished by such generating corporation to such industrial corporation for use and consumption by such industrial corporation or for use upon the premises of such industrial corporation by its bono fide operatives or employees, but the tax shall be paid upon so much of such power as may be sold to other than such industrial corporation's employees.
8. Electric power sold to industrial customers as a class in excess of the amounts of electric power sold to industrial customers as a class during the corresponding months of SC's fiscal year 1957 - 1958; but all sales of electric power to any class of customer other than industrial customers shall continue to be assessed and taxed as provided in this article. As used in this section, "industrial customers" shall mean that class of customer engaged in the business of manufacture, fabrication, processing and related work.

Yes. Section 12-23-130 exempts the S.C. Public Service Authority from the electric power tax and states:

Public Service Authority, and all property leased to and operated by the S.C. Public Service Authority for the generation or transmission of electric power shall, for all tax purposes, be considered the property of the Authority.

Section 12-23-20 (8) states "Industrial customers shall mean that class of customers engaged in the business of manufacture, fabrication, processing and related work."
