Transmission Line Projects

Construction and operation of transmission lines and/or facilities above 115 kV in Virginia usually require the issuance of a Certificate of Public Convenience and Necessity (CPCN) from the State Corporation Commission. Staff guidelines on transmission projects that require a CPCN, and Guidelines of Minimum Requirements for Transmission Line Applications, are available among our guidance documents.
