Public Service Company of Oklahoma (PSO), in conjunction with AEP Oklahoma Transmission Company announced plans to invest in electric transmission infrastructure in Beckham, Kiowa and Washita counties. The Western Oklahoma Transmission Reinforcement Project will address existing system overloads as well as ensure reliable electric service and capacity for future growth in the region.

Plans include building a new substation approximately 15 miles west of Elk City. In addition, the company will construct approximately 70 miles of new 345-kilovolt (kV) transmission lines starting at the proposed substation and travelling east to connect with an OG&E 345 kV transmission line near Mountain View. The investments are expected to total an estimated $120 million.

Plans call for the project to be complete in 2018. Before work begins, the company will identify preliminary line routes and seek input from the public.
