Approved Projects

Broken Arrow - Tulsa Electric Transmission Improvements

Public Service Company of Oklahoma, in conjunction with AEP Oklahoma Transmission Company, is planning to rebuild approximately five miles of existing transmission line from Broken Arrow to Tulsa. Upgrades to the existing 69-kilovolt (kV) system include removing current transmission facilities and replacing them with sturdier facilities. This project is the final phase of a greater initiative to rebuild approximately 49 miles of line from Chouteau to PSO’s Tulsa Southeast Substation. These improvements will bring the facilities up to current standards and thereby enhance reliability.

Broken Bow - Lone Oak Upgrades

AEP Oklahoma Transmission Company, an affiliate of Public Service Company of Oklahoma (PSO), is planning improvements to the local electric transmission system to ensure continued reliable power delivery to southeastern Oklahoma. The Broken Bow to Lone Oak upgrades extend from an existing hydro-electric generation plant located near Broken Bow approximately 80 miles northwest to PSO’s Lone Oak substation. Improvements to the existing 138 kV line are necessary to enhance long-term reliability and support continuous growth in the region.

Darlington Road – Roman Nose

Public Service Company of Oklahoma, in conjunction with AEP Oklahoma Transmission Company, is planning to build approximately 13 miles of 138 kilovolt (kV) transmission line from a substation near Calumet to a point of interconnection with OG&E near Geary, OK. This investment is necessary to provide overload relief and ensure capacity for future growth in the area.

Maud to Weleetka Transmission Improvements

AEP Oklahoma Transmission Company, an affiliate of Public Service Company of Oklahoma (PSO), is planning to rebuild approximately 49 miles of electric transmission line to bring the system up to current standards and ensure continued reliable power. The line originates at an existing PSO substation south of Weleetka, then heads west towards Earlsboro before turning south to reach an OG&E substation located west of Maud. The rebuild project will involve removing existing transmission facilities and replacing them with steel structures and new wire. These improvements are necessary to ensure the continued reliability of the electrical system.

McAlester Area Improvements

Public Service Company of Oklahoma, in conjunction with AEP Oklahoma Transmission Company, is planning to invest approximately $19 million in electrical infrastructure upgrades in order to meet capacity needs for the City of McAlester and the Steven Taylor Industrial Park. Plans call for the addition of two new substations and approximately 8 miles of 138 kilovolt (kV) transmission line. The enhancements will benefit the area by increasing system capacity, improving reliability and allowing the company to more effectively isolate outages when they occur.

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 equipment and line and some minor upgrades to surrounding substations. These improvements will continue through 2020.

Western Oklahoma Transmission Reinforcement Project

AEP Oklahoma Transmission Company, an affiliate of Public Service Company of Oklahoma (PSO), is planning significant improvements to the electric transmission system to ensure continued reliable power in western Oklahoma. The Western Oklahoma Transmission Reinforcement Project includes the following:

  • Building a new substation
  • Constructing a new 345-kilovolt (kV) transmission line from west of Elk City to a point of interconnection with Oklahoma Gas & Electric Company (OG&E) near Mountain View.
These investments are necessary to address existing system overloads and enhance long-term reliability in the region.
