Wyo. Stat. Ann. § 37-13-130

The public utility concerned is responsible for all construction work involving its facilities and may contract out such of this construction work as it deems desirable. There shall be no competitive bidding as to the construction of the converted facilities since existing facilities are owned and operated by the public utility and the continuity of service of the public utility is essential. Title to the converted facilities is solely in the public utility involved. The public is only purchasing the intangible benefits which come from removal of the overhead facilities and replacement by underground facilities.
