South Caldwell - Macksburg 138kV Transmission Line Project

    The proposed South Caldwell-Macksburg transmission line is part of the overall Marietta Area Improvements Project. The 23-kilovolt (kV) infrastructure has reached an age where it is in need of rebuild and redesign to improve reliability for the customers across the region. Bringing additional power sources into the region will improve the electric service reliability.

    The South Caldwell-Macksburg transmission line is a 138-kV transmission line that connects South Caldwell Substation -- passing through South Olive Substation, in Noble County -- to Macksburg Substation in Washington County. This project will improve service for customers, decrease power interruptions and speed recovery of service when outages occur.

    The South Caldwell-Macksburg line will be approximately eight miles long, depending on the route selected. The line will likely run through Olive, Jackson and Jefferson townships in Noble County with a short section in Aurelius Township in Washington County.

    AEP Ohio projects South Caldwell-Macksburg, an approximate $15 million investment, will contribute approximately $660,000 in property taxes annually to the community.
