(1) Notwithstanding the provisions of Section 77-3-11, Mississippi Code of 1972, and Section 77-3-13, Mississippi Code of 1972, no public utility or other person shall begin the construction of any facility for the generation and transmission of electricity to be directly or indirectly used for the furnishing of public utility service in this state, even though the facility be for furnishing the service already being rendered, without first obtaining from the commission a certificate that the public convenience and necessity requires, or will require, such construction.

(2) The commission shall develop, publicize and keep current an analysis of the long-range needs for expansion of facilities for the generation of electricity in Mississippi, including its estimate of the probable future growth of the use of electricity, the probable needed generation reserves, the extent, size, mix and general location of generating plants and arrangements for pooling power to the extent not regulated by the Federal Energy Regulatory Commission and other arrangements with other utilities and energy suppliers to achieve maximum efficiencies for the benefit of the people of Mississippi, and shall consider such analysis in acting upon any petition by any utility for construction. Each public utility engaged in the generation, transmission and distribution of electric energy shall, upon request of the commission, submit to the commission its forecasts and plans for the addition of generating capacity planned by the utility for an ensuing five-year period and shall furnish to the commission such documents and proof with respect to the need therefor as the commission may reasonably require. In considering these analyses and forecasts, the commission shall consult with the University Research Center, the utilities commissions or comparable agencies of neighboring states, the Federal Energy Regulatory Commission and other agencies having relevant information and/or duties and responsibilities in this area, and particularly with the Department of Economic and Community Development with reference to the accomplishment of the Mississippi Energy Plan provided for in Section 57-39-11, Mississippi Code of 1972.

(3) In acting upon any petition for the construction of any facility for the generation of electricity, the commission shall take into account the utility’s arrangements with other electric utilities for interchange of power, pooling of plant, purchase of power and other methods for providing reliable, efficient and economical electric service.

(4) As a condition for receiving such certificate, the utility shall file an estimate of construction costs in such detail as the commission may require. The commission shall hold a public hearing on each application, and no certificate shall be granted unless the commission has approved the estimated construction costs.

(5) The commission shall maintain an ongoing review of such construction as it proceeds, and the applicant shall submit at such times as the commission shall require during construction a progress report and any revisions in the cost estimates for the construction.

(6) The certification requirements of this section shall not apply to persons who construct an electric generating facility primarily for that person’s own use and not for the primary purpose of producing electricity, heat or steam for sale to or for the public for compensation; and the commission may provide for exemption from certification requirements for cogeneration facilities and small standby facilities; provided, however, that such persons shall, nevertheless, be required to report to the commission the proposed construction of such a facility before beginning construction thereof.
