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.
Information for all cases before the Commission is made available through the SCC's DocketSearch portal. Public comments related to Commission cases are accepted for a limited time. Cases for which comments are currently being accepted are listed on the Public Comments/Notices page.
