For Oncor and LCRA TSC to continue to provide safe and reliable electric service in this area, a new 765 kV transmission line is needed. The Project would connect a new LCRA TSC 765 kV Big Hill Substation, located in close proximity to LCRA TSC’s existing Big Hill 345 kV Substation 13 miles northeast of the City of Eldorado in Schleicher County, Texas, and the expansion of Oncor’s existing Bell County East Switch, located 5.5 miles southeast of the City of Temple in Bell County, Texas. The Proposed Transmission Line Project is currently planned for completion in summer 2030.
Voltage and Structure Type
The project includes a new 765 kV single-circuit transmission line constructed on self-supporting, steel lattice towers.
