North Dakota Century Code Title 49. Public Utilities § 49-03-01.3. Exclusions from limitations on electric distribution lines, extension, and service and on issuance of certificates of public convenience and necessity

Sections 49-03-01 through 49-03-01.5 shall not be construed to require any such electric public utility to secure such order or certificate for an extension of its electric distribution lines within the corporate limits of any municipality within which it has lawfully commenced operations; provided, however, that such extension or extensions shall not interfere with existing services provided by a rural electric cooperative or another electric public utility within such municipality; and provided duplication of services is not deemed unreasonable by the commission.

Sections 49-03-01 through 49-03-01.5 shall not be construed to require an electric public utility to discontinue service to customers thereof whose places receiving service are located outside the corporate limits of a municipality on July 1, 1965; provided, however, that within ninety days after July 1, 1965, any electric public utility furnishing service to customers whose places receiving service are located outside the corporate limits of a municipality shall file with the commission a complete map or maps of its electric distribution system showing all places in North Dakota which are located outside the corporate limits of a municipality and which are receiving its service as of July 1, 1965. After ninety days from July 1, 1965, unless a customer whose place being served is located outside the corporate limits of a municipality is shown on said map or maps, it shall be conclusively presumed that such customer was not being served on July 1, 1965, and cannot be served until after compliance with the provisions of section 49-03-01.1.
