Sooner-Wekiwa Project


Sooner-Wekiwa Project

Transource plans to develop the Sooner-Wekiwa Project, a new overhead electric transmission line in Oklahoma designed to save customers hundreds of millions of dollars.

The Southwest Power Pool (SPP) awarded Transource the opportunity to construct a new electric transmission line in Oklahoma to address deficiencies in the electric grid and improve consumer access to low-cost power in Oklahoma as well as some customers in Arkansas, Missouri, Texas and Louisiana, while providing $16.8 million in congestion savings during the first year and $465.6 million over the next 40 years.

The Sooner-Wekiwa Project involves:

  • Building approximately 80 miles of 345-kilovolt (kV) electric transmission line from Oklahoma Gas & Electric’s Sooner Substation in Noble County to Public Service Company of Oklahoma’s (PSO) Wekiwa Substation in Tulsa County
  • Upgrading the Sooner and Wekiwa substations to integrate the facilities into the grid

Transource plans to build the new overhead electric transmission line connecting the two substations. The incumbent utilities will each make upgrades at their respective substations.

Plans include building about 25 miles of the transmission line in PSO’s service territory.
