The Legislature of the State of Alabama has investigated the economic, financial and environmental impact associated with the potential for duplication of electric distribution facilities used for the furnishing of retail electric service. Among its findings are the conclusion that with respect to retail electric sales, the benefit normally associated with competition between two or more entities for customers is outweighed by the tremendous cost burden which must be borne by such customers associated with the maintenance of two or more duplicate sets of facilities. It is the further finding of the legislature that the existence of duplicate facilities for the furnishing of electricity at retail is not in the public interest because of the adverse impact which such duplication has on environmental and aesthetic values and on safety. It is therefore declared that the policy of the State of Alabama is to ensure effective, economical and orderly supply of electric service at retail to customers in the state and to avoid unnecessary duplication of facilities by electric suppliers for the furnishing of such services which would result in waste and in degradation of the environment. To accomplish these objectives, it is necessary and in the public interest to establish, mandate and implement procedures for determining which electric supplier shall furnish electric service to customers at retail within various areas of the state including areas within present and future corporate limits of municipalities in the state.
