Mountain Home Transmission Project

Example transmission structure for proposed project.

The Mountain Home Transmission Project is designed to bring transmission infrastructure to growing areas in Gillespie, Kimble and Kerr counties in Texas. The proposed project includes construction of a new 138-kilovolt (kV) load-serving Mountain Home Substation and a new 138-kV transmission line connecting the Mountain Home Substation to existing substations located in Harper and either Ingram or Hunt. In order to construct and operate these facilities, LCRA Transmission Services Corporation is preparing an application for an amendment to its existing Certificate of Convenience and Necessity that will be filed with the Public Utility Commission of Texas.
