McAlester - Atoka Transmission Line Rebuild

    Southeast Oklahoma Area Improvements

    The Southeast Oklahoma Area Improvements Project is an approximately $105 million investment designed to ensure continued reliable power and support local economic growth and development. The multi-phase project includes rebuilding about 125 miles of transmission line, upgrading about 5 miles of distribution line and equipment, and making minor upgrades to surrounding substations. These improvements will continue through 2020.

    AEP Public Service Company of Oklahoma (PSO) plans to rebuild about 35 miles of electric transmission line to bring the system to current standards and ensure continued reliable power. The line was originally built in 1963 and needs to be improved to better serve the area. These upgrades will benefit the region by strengthening the transmission system and improving its reliability in the future.


    The project will involve removing about 35 miles of existing wood poles. The majority of the new poles will be steel single-pole structures. The electric wire will also be replaced.


    Southwest Power Pool (SPP), the regional transmission organization, along with PSO field personnel identified the need for these upgrades to address local electricity supply concerns. SPP operates under federal mandate to ensure reliable supplies of power and adequate transmission infrastructure. Updating the area’s transmission system will also support future economic growth and development.
