CPS Energy is proposing to construct a new 138 kV substation and approximately two miles of new 138 kV transmission corridor in Medina County. The proposed transmission lines will require new Right of Way (ROW). One double-circuit transmission line will connect the new substation to the CPS Energy transmission system and the other single-circuit transmission line will connect the CPS Energy substation to the STEC San Geronimo substation.
