Vermont has three types of electric utilities: investor owned utilities (1), municipal electric departments (14); and member-owned rural electric cooperatives (2). These seventeen electric distribution companies range in size from small municipal electric departments with a few hundred customers to one large investor owned utility (Green Mountain Power which merged with Central Vermont Public Service as of July 1, 2012) with more than 255,647 customers.
Vermont electric utilities are regulated monopolies and operate under a Certificate of Public Good (CPG) granted by the Vermont Public Service Board (Board). As regulated monopolies, rates and policies are subject to review by the Public Service Department (PSD) with approval by the Board. The Board maintains the Official Listing of Vermont Electric Utilities that operate under a CPG.
Vermont is the only state in New England that has chosen not to restructure its electric industry by adopting retail competition. Because Vermont utilities own few of their own generation resources and participate in the New England electric wholesale market, they share many characteristics with distribution companies in other New England states that have restructured.
