A Certificate of Public Convenience and Necessity

The Colorado Public Utilities Law (Colorado Revised Statutes § 40-1-101, et seq.) and the rules of the Colorado Public Utilities Commission (CPUC) (4 Code of Colorado Regulations 723-3) require that an electric utility seeking to construct and operate an electric transmission line must first obtain a Certificate of Public Convenience and Need (CPCN) for the transmission line unless the CPUC determines that construction of the line is in the ordinary course of business in which case, a CPCN is not needed for the transmission line project.

In the case of a proposed electric transmission line, a CPCN application must include the following information:

  • A statement of facts showing how the proposed transmission line is required for the public convenience and necessity
  • A description of the proposed transmission line
  • The estimated cost of the proposed transmission line
  • The anticipated construction time frame and in-service date for the transmission line
  • Maps showing the general area of the line, population centers, major highways, and county and state boundaries
  • Electrical diagrams of the proposed transmission line
  • Information on alternatives studied and the criteria used to rank such alternatives
  • A report on prudent avoidance measures relating to exposure to magnetic fields associated with the proposed transmission line
  • Information concerning projected audible noise levels associated with the transmission line and cost-effective mitigation measures

This information is considered by the CPUC when determining the need for the proposed transmission line. It is important to note that the CPCN process does not decide the final location of the transmission line. The final location and alignment of the transmission line is determined through a separate and extensive federal, state, and local government siting and permitting process.
