Siloam Springs Transmission Improvements Project

    SWEPCO plans to make improvements to the local electric transmission system to ensure continued reliable power delivery to northwest Arkansas.

    The Siloam Springs Transmission Improvements Project consists of rebuilding about two miles of 161-kilovolt (kV) transmission line to ensure continued reliable service to customers.

    Construction is expected to start in early 2019 and be completed by Summer 2019. The estimated project budget is $4 million.

    Project Updates

    As the project moves forward this summer, right-of-way agents will soon be in contact with landowners to discuss any supplemental easements along the existing transmission line route. These supplemental easements are voluntary; however, they do help to update the easement agreement to modern standards for safe operation and maintenance of the existing transmission line.

    SWEPCO Transmission Forestry teams will begin reviewing the existing right-of-way and determining maintenance clearing needs for safe rebuild and operation of the existing transmission line. Forestry crews expect to begin their right-of-way maintenance clearing mid-September 2018 and will be complete by the end of the year.



    • Some landowners have recently received inaccurate information regarding the project. SWEPCO does not plan to use eminent domain on this rebuild project. The transmission line is currently located within company-owned easements and will be rebuilt according to the current easement rights. We may seek voluntary supplemental easements in some cases to update them to current standards, but again, eminent domain is not involved.

    • In March, crews will begin survey activities along and adjacent to the transmission line route to gather data for final engineering of the rebuilding of the line. The survey work is expected to be complete by the end of April, weather permitting.

    • Volkert, Inc. is representing SWEPCO as the right-of-way representative on this project and will work closely with landowners as the project moves forward.
