Wyo. Stat. Ann. § 15-1-410
in effect(a) The territory and inhabitants of any annexed area are subject to all the laws, ordinances, rules and regulations of the city or town to which they are annexed and are entitled to all the rights, privileges and franchises or other services afforded the inhabitants thereof. The services shall be provided in accordance with the timetable provided pursuant to W.S. 15-1-402(c)(iii). Notwithstanding any other provision of law, no law, ordinance, rule or regulation of a municipality annexing property under W.S. 15-1-404 shall restrict the continuous use of the property by a current or subsequent owner of an interest in the property, if the use was existing at any time within the year prior to the date of annexation and was lawful at the time the property was annexed. For purposes of this subsection, a use which has been discontinued for any one (1) year period after the date of annexation shall not be considered continuous and shall not thereafter be reestablished unless in conformance with current law, ordinance, rule or regulation.
(b) The governing body of the annexing municipality shall, within thirty (30) days after the date of the annexation, give written notice of the annexation to all public electric utilities presently providing service within the annexed area and, except in the case of an annexing municipality which owns or operates its own electric utility, any area adjacent to the annexed area. Except in the case of an annexing municipality which owns or operates its own electric utility, any of those public utilities required to be notified may, within sixty (60) days after the date of annexation, petition the governing body of the annexing city or town for a franchise to serve additional portions within the annexed area or the entire annexed area. Except in the case of a municipality which owns or operates its own electric utility, any petitioning utility which does not currently hold a certificate of public convenience and necessity for the annexed area shall petition the public service commission for a certificate to include the annexed area, and if two (2) or more public electric utilities have been granted or are seeking a certificate of public convenience and necessity to serve the annexed area, the public service commission shall determine, following a hearing, which utility or utilities should be certificated in the public interest to provide service to the annexed area. No recipient of a certificate of public convenience and necessity shall serve any portion of the annexed area without the consent of the governing body of the annexing city or town and provided that the entire annexed area is served under one (1) or more certificates of public convenience and necessity.
(c) Except in the case of an annexing municipality which owns or operates its own electric utility, the governing body of the annexing municipality shall hold an appropriate public hearing and, upon determining that one (1) or more petitioning public utilities can meet the terms and conditions of a franchise, issue franchises to one (1) or more utilities to serve portions of or the entire annexed area.
(d) Notwithstanding any other provision of law, nothing contained in this section shall limit the right of a municipality which owns or operates its own electric utility to extend its electric service into any area annexed by the municipality, and nothing contained in this section shall subject any such municipality to the jurisdiction of the public service commission.
