To continue to provide safe and reliable electric service in this area, Oncor Electric Delivery Company LLC (Oncor) is proposing to construct a double-circuit 138 kV transmission line in Nolan County, with both circuits operational, between Oncor’s existing Plowboy Substation to Oncor’s planned Oak Spring Switch. The existing Plowboy Substation is located approximately 0.90 miles west-northwest of the intersection of Interstate Highway (IH) 20 and United States Highway (US) 84. The planned Oak Spring Switch is located approximately 1.52 miles south-southeast of the intersection of IH 20 and Farm to Market Road (FM) 608. The Proposed Transmission Line Project is currently planned for completion in 2028.
Voltage and Structure Type – The project includes a new 138 kV Double Circuit Transmission Line, approximately 3 miles in length. The structure will be constructed on self-supporting monopole structures.
