Henne-McCarty Lane Transmission Line Upgrade
The project goes from the Henne Substation near exit 195 on Interstate 35 to the McCarty substation south of San Marcos.
LCRA Transmission Service Corporation (TSC) will upgrade the existing 6.6-mile, 138-kilovolt (kV) transmission line by replacing the existing steel lattice structures with new steel poles and installing new conductors to increase the electrical capacity of the line. Some substation equipment will also be upgraded at the Henne substation.
This area between San Marcos and New Braunfels is experiencing significant growth, which is expected to continue. This upgrade will address the need for increased capacity and reliability in the corridor between New Braunfels and San Marcos, and the surrounding areas.
