North McCamey to Sand Lake Transmission Project

LCRA TSC and Oncor are jointly proposing to build and operate a new 345-kilovolt transmission line to improve reliability and accommodate future demand and generating capacity growth in West Texas. The new transmission line is planned for portions of Crane, Crockett, Pecos, Reeves, Upton and Ward counties. It will connect LCRA TSC’s existing North McCamey Substation in Upton County with Oncor’s existing Sand Lake Substation in Reeves County, which are about 75 miles apart.

The project requires LCRA TSC and Oncor to amend their certificates of convenience and necessity (CCNs) with the Public Utility Commission of Texas. As part of the process, LCRA TSC and Oncor will seek input from state and local elected officials and various agencies to identify routing constraints to help determine potential locations for new transmission facilities and assess the project’s potential impacts. LCRA TSC and ONCOR will hold open houses for the public to learn more about the project and provide their feedback.

PUC selects route for transmission line
The Public Utility Commission of Texas approved Route 65 consisting of the following links: A1-A2-A6-A9-C3-D2-E3-E6b-E8-E9-G3-G7-G9-G10-I12-M4-M8-O3-P4-P7-R3-R6-R10-T2-T4. See the ruling [PDF].

Application filed with the Public Utility Commission of Texas
LCRA TSC and Oncor filed an application with the Public Utility Commission of Texas (PUC) on June 22 to amend their Certificates of Convenience and Necessity for the North McCamey to Sand Lake 345-kV Transmission Line Project. The application includes data on 82 alternative routes that range from approximately 87 to 107 miles. Numerous other routes could be created by combining the filed segments into additional routes. The route order is numerical and does not signify any preference on LCRA TSC’s or Oncor’s part as to which route is ultimately approved.

In the application, LCRA TSC and Oncor identify Route 65 (consisting of links A1-A2-A6-A9-C3-D2-E3-E6b-E8-E9-G3-G7-G9-G10-I12-M4-M8-O3-P4-P7-R3-R6-R10-T2-T4) as the filed route that LCRA TSC and Oncor believe best addresses the PUC’s routing criteria. LCRA TSC and Oncor based this on factors such as Route 65’s relatively low estimated cost and short length, and other
criteria relating to the overall manner in which Route 65 minimizes impacts to the community by following existing rights of way, minimizing the number of habitable structures within proximity to the project, and minimizing impacts to natural and cultural resources.

All routes and route links included in the application — available at the link above — are available for selection and approval by the PUC. The deadline for intervention in PUC docket No. 55121 is Aug. 7, 2023. If approved by the PUC, the transmission line is scheduled to be energized by June 2026.
