SANDLAKE – NORTH MCCAMEY 345 KV TRANSMISSION LINE PROJECT

Oncor Electric Delivery Company LLC (“Oncor”) and Lower Colorado River Authority Transmission Services Corp. (“LCRA TSC”) continue to monitor electric demand in West Texas due to significant increases in oil and gas production, transportation, mid-stream processing, and other activities in the Permian Basin. In support of this continued load growth, Oncor and LCRA TSC propose to construct a double-circuit 345 kV transmission line (project) located within Crane, Reeves, Ward, Crockett and Pecos Counties. The proposed project would connect the North McCamey Station, which is located approximately 0.6 mile north of the City of McCamey, and the Sand Lake Station, which is located approximately 6 miles northeast of the City of Pecos on the northwest side of Farm-to-Market Road (FM) 3398. Completion of the new project will provide an essential transmission-level electric source to the area to facilitate future developments and maintenance needs and to generally improve electric reliability to the area. The project has been independently reviewed and endorsed by the Electric Reliability Council of Texas (“ERCOT”) as critical to the reliability of the ERCOT transmission system. The proposed transmission line will be approximately 90-100 miles in length, if approved by the Public Utility Commission of Texas (“PUC”).

 

Voltage and Structure Type - The project is a double-circuit capable 345 kV transmission line constructed on steel lattice towers.
