LCRA TSC's Leander-Round Rock
Transmission Line Project​

Lower Colorado River Authority Transmission Services Corporation (LCRA TSC) is proposing to build and operate a new 138-kilovolt (kV) transmission line located in southwestern Williamson County. The proposed project consists of constructing a new 138-kV transmission line to connect two new substations to the existing Leander and Round Rock substations.

On April 28 the LCRA TSC filed an application with the Public Utility Commission of Texas (PUC) to amend its Certificate of Convenience and Necessity for the Leander-Round Rock Transmission Project. The application includes data on 31 alternate routes that range from approximately 12 to 21 miles long and are estimated to cost from $67.8 to $99.6 million. Numerous other routes could be created by combining the filed segments into additional routes.

In its application, LCRA TSC identifies Route 31 as the filed route that LCRA TSC believes best addresses the routing requirements of the Public Utility Regulatory Act and the regulations of the Public Utility Commission of Texas. You can use an interactive mapping tool to see the various alternative routes proposed in the filing.

This infrastructure is needed to support the growing population and energy needs of the region. LCRA TSC is working on this project with the Public Utility Commission (PUC), which will make the final decision on the route to be constructed. It is PEC’s understanding that the proposed segments are based on a number of factors including cost, public input, environmental considerations, aesthetics, cost and land use.

Members who would like to give input on the proposed lines can visit lcra.org/lrr or call 512-578-7051 for more information.
