    Trade Zone 138-kilovolt Substation

    The Trade Zone 138-kilovolt (kV) Substation project includes plans to build the new Trade Zone 138-kV Substation in south McAllen and connect the substation to the existing South McAllen - Las Milpas 138-kV transmission line. Plans also involve completing minor upgrades to the distribution system before connecting it to the new substation.

    Substation Construction: Spring 2019 - Summer 2020
    Line Construction: Fall 2019 - Summer 2020
    In-Service Date: Summer 2020

    Facilities

    Trade Zone Substation facilities will be approximately 230 feet x 230 feet within a 5 acre area.

    Plans include creating a detention basin at the entrance to the substation approximately 145 feet x 100 feet and approximately 4 feet deep.

    The detention basin helps protect the area around the substation against flooding when large amounts of rainfall occur. The detention basin is designed to hold water for a limited amount of time to allow for draining.
