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.

The proposed loop location along Oncor’s existing Jewett Switch – Crockett Switch 138 kV Line, where the project commences, is located approximately 2.1 miles east of the intersection of State Highway (“SH”) 7 and Farm to Market Road (“FM”) 542 in Leon County, Texas. The proposed Glaze Lake Switch property is located approximately 0.13 miles northeast of the intersection of FM 542 and County Road (“CR”) 250. The proposed Leon Solar POI will be located approximately 0.4 miles northeast of the proposed Glaze Lake Switch. The project is approximately 9.7 miles in length between the loop location on Oncor’s existing Jewett Switch – Crockett Switch 138 kV Line and the proposed Glaze Lake Switch, and it is approximately 0.4 miles in length between the proposed Glaze Lake Switch and the proposed Leon Solar POI and constructed entirely within right-of-way that has already been acquired for this project, if approved by the Public Utility Commission of Texas (PUC). The proposed project is currently planned for completion in November 2025.

Voltage and Structure Type – The project includes a new double-circuit 138 kV transmission line, constructed on steel monopole structures.

Oncor Electric Delivery Company LLC (Oncor) proposes to construct a new double-circuit 138 kilovolt (kV) transmission line within the cities of Arlington and Grand Prairie, Texas. The proposed transmission line will begin at Oncor’s proposed Division Substation, to be located southwest of Division Street and Stadium Drive. From that location, the proposed transmission line will extend east to an intermediate point along the existing Executive Parkway Switch–Sherry Switch transmission line located between the proposed Division Substation and State Highway (SH) 360. The proposed transmission line will then follow this existing transmission line corridor to the north of Division Street, before continuing eastward to a potential endpoint along the existing Liggett Switch–Cedar Hill Switch 138 kV transmission line, located east of SH 360. The exact locations of the intermediate point along the Executive Parkway Switch–Sherry Switch transmission line and of the eastern endpoint along the Liggett Switch–Cedar Hill Switch transmission line will be subject to selection and approval by the Public Utility Commission of Texas (PUCT).

Voltage and Structure Type – The project includes a new double-circuit 138 kV transmission line, constructed on steel monopole structures.

Public Meeting – Notice of the public meeting notice will be published in the local newspaper during the week of 3/17/25. Public Meetings will be held on Monday and Tuesday, March 24-25, 2025 at the Hilton Arlington at 2401 East Lamar Blvd. Arlington, Texas 76006 from 4:00 - 7:00PM.
