The Shepherd Substation was recently built here: it hosts a 138-kV transmission line with 1 transformer. Verify if there are 2, 3, or 4 switches.
The 138-kV transmission line travels northbound past the Medina River, then heads northeast. The new line merges onto the 138-kV line going from the Howard Substation to the Cagnon Substation. The merge takes place at Power Tower 166.
