Miss. Code § 77-5-447
This article is for the public purpose of promoting the increased use of electricity in the urban and rural areas of this state, and to enable all counties, as well as cities and towns, to secure the benefit of the surplus power generated or to be generated by the Tennessee Valley Authority at Wilson Dam in the State of Alabama and Norris Dam in the State of Tennessee, or the power generated at any other works or dams. This article is remedial in nature and the powers granted in it shall be liberally construed to effectuate the purposes hereof, and to this end every municipality shall have power to do all things necessary or convenient to carry out the purposes hereof in addition to the powers expressly conferred in this article.
The powers conferred by this article shall be in addition and supplemental to the powers conferred by any other law. Bonds may be issued under the provisions of this article for the acquisition or improvement of an electric plant notwithstanding that any other law may provide for the issuance of bonds for like purposes and without regard to the requirements, restrictions or procedural provisions contained in any other law. Any proceedings heretofore taken by any municipality relating to the subject-matter of this article, whether or not commenced under any other law, may at the option of the governing body, be discontinued and new proceedings instituted under this article.
