Oncor Electric Delivery Company LLC (Oncor) has applied to amend its certificate of convenience and necessity to construct, own, and operate a new, double-circuit 138 kV loop transmission line to be built on double-circuit steel monopoles between Oncor’s existing Jewett Switch – Crockett Switch 138 kV Line and the proposed Glaze Lake Switch. Between the proposed Glaze Lake Switch and the proposed 138 kV point of interconnection (“POI”) for the proposed Leon Solar Park generation facility (“Leon Solar POI”), Oncor will construct double-circuit, 138 kV capable steel monopoles, with one 138 kV circuit installed initially.
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.
