Clinton - Foss TapTransmission Line Rebuild Project

Public Service Company of Oklahoma (PSO) representatives plan power grid upgrades to the 69-kilovolt Clinton Junction-Clinton City and Foss Water Plant Tap electric transmission lines. This project involves rebuilding about 18 miles of power line with steel single-pole structures.

Project Updates

Late Fall 2022: As PSO representatives prepare to rebuild the line, crews plan to start installing gates and culverts in mid-January 2023 on select properties along the power line route. These allow PSO representatives to safely access areas within the company’s easements. Crews plan to conclude this work by the end of January 2023, weather permitting. Crews plan to start rebuilding the Clinton Junction - Clinton City portion of this project in early 2023. The Foss Tap portion of this project will start in early 2024. PSO representatives expect the project to finish in spring 2024.

Early 2022 - Spring 2022: TRC Companies, Inc., serves as PSO’s right-of-way representative for this project. TRC representatives are contacting affected landowners to discuss field activities, easement acquisition and construction.

Spring 2021: PSO crews and contractors performed preliminary surveying work.

*Easements are defined land rights that property owners grant the utility to allow for the safe construction, operation and maintenance of the power line.
