Sooner - Wekiwa Project

    The Sooner-Wekiwa Project increases consumer access to more affordable power in Oklahoma as well as parts of Arkansas, Missouri, Texas and Louisiana.

    The Southwest Power Pool (SPP) awarded Transource the opportunity to construct an electric transmission line in Oklahoma to address deficiencies in the electric grid and improve consumer access to low-cost power.

    The Sooner-Wekiwa Project involves:

    • Building 76 miles of 345-kV electric transmission line from Oklahoma Gas & Electric’s (OG&E) Sooner Substation in Noble County to Public Service Company of Oklahoma’s (PSO) Wekiwa Substation in Tulsa County
    • Upgrading the Sooner and Wekiwa substations to integrate the facilities into the grid

    Construction on the new line begins spring 2024 and concludes in late 2025. According to SPP, the project is expected to provide an estimated $16.8 million in congestion savings during the first year and $465.6 million over the next 40 years.

    Additional Project Details

    Transource representatives plan to build the new transmission line in an approximately 130-foot-wide right-of-way corridor to ensure the safe construction, operation and maintenance of the facilities.

    Typical regional farming practices can continue within the right-of-way, right up to the structure, and landowners will be fairly compensated for easements required to build the line, as well as potential impacts, such as crop loss during construction and restoration.

    Transource treats people and the environment with respect in constructing new facilities. Transource prioritizes proactive and early engagement with landowners and stakeholders. If your property is involved on the final route, a right-of-way agent will contact you to negotiate easements and compensation.
