Public Service Company of Oklahoma, in conjunction with AEP Oklahoma Transmission Company, built approximately 13 miles of new 138-kilovolt (kV) transmission line from a substation near Calumet to a point of interconnection with OG&E near Geary, OK.
The need for this project was driven by growing power demand in the area and Southwest Power Pool (SPP). SPP, a regional transmission organization, identified the need for these upgrades to bolster the local electric transmission system and provide continued reliable power to Canadian county.
The company’s estimated investment on this project is approximately $11 million and was completed and placed in-service in June 2017. Right-of-way restoration is still underway and is expected to be complete later this year.
