Municipal electric utilities must file for construction authority if construction projects exceed a certain cost threshold. These filing requirements cover the generally small construction projects normally proposed by municipal electric utilities. These projects are most always classified as Type III (or less commonly as Type II) projects under Wis. Admin. Code ch. PSC 4. Projects can include new or expanded buildings, new or expanded substations, certain transmission and/or distribution construction or upgrade projects, and small generation projects. In order to obtain construction authority, an application must be filed with the Commission. In order to prepare a complete application, the following filing requirements must be followed.
