South ChickashaTransmission Improvements Project

Public Service Company of Oklahoma (PSO) representatives plan to rebuild about 5 miles of 138-kilovolt power line in Grady County to improve electric reliability for area customers. Crews plan to begin construction in early fall 2023 and conclude in early 2024.

The South Chickasha Transmission Improvements Project also involves upgrading wires and making minor upgrades to substation equipment along the line route.

Project Updates

Summer 2022: TRC Companies, Inc., serves as PSO’s right-of-way representative for this project. TRC right-of-way agents plan to contact affected landowners to discuss field activities, easement acquisition and construction.

Early 2022: PSO crews and contractors performed surveying work in early 2022 within the utility's right-of-way along and adjacent to the line route.

*Company representatives plan to rebuild the power line in the existing right-of-way, which may require acquiring new or updating existing property easements. Easements are defined land rights that property owners grand the utility to allow for the safe construction, operation and maintenance of the power line.
