S.C. Code § 6-23-30
In addition and supplemental to the powers granted to municipalities of the State, and in order to accomplish the purpose of this chapter, a municipality may plan, finance, develop, acquire, purchase, construct, reconstruct, improve, enlarge, own, operate, and maintain an undivided interest as a tenant-in-common in a project situated within or without the State jointly with one or more municipalities in this State or any other state, owning electric distribution facilities, or with any political subdivisions or agencies of any other state, and may make these plans and enter into these contracts in connection with them, not inconsistent with the provisions of this chapter, as are necessary or appropriate; provided, all municipal tenants-in-common must be located within the area generally served by the same electric supplier. The acquisition of a project or projects by municipalities as tenants-in-common by purchase is limited to a project or projects under construction on the date of approval of this chapter, or a project or projects on which construction will commence subsequent to the date of approval of this chapter. The amount of capacity and output of a project purchased by municipal tenants-in-common may not be less than ten percent of the rated capacity of the project.
Municipal tenants-in-common pursuant to the provisions of this section, by contract, may waive their right of partition either in kind or by sale. The power and right to enter into agreements to waive the right of judicial partition authorized by this section are in addition to these powers and rights already authorized by the laws of South Carolina.
Nothing contained in this section prevents a municipality or municipalities from undertaking studies to determine whether there is a need for a project or whether the project is feasible.
