Prairie Wind TransmissionPrairie Wind Transmission
Joint venture between Westar and Electric Transmission America (ETA)
ETA is owned 50/50 by AEP and Mid American
AEP is the only utility in nation that has 765kV in operation
AEP has designed, constructed and operated 765kV for almost 40 years

Prairie Wind TransmissionPrairie Wind Transmission
Prairie Wind was formed to design, construct and operate the first 765kV transmission west of the Mississippi
SPP’s consultant Quanta identified the Prairie Wind project as the logical first step in building a 765kV overlay in the SPP
Coupled with the Tallgrass Project announced by Oklahoma Gas & Electric and ETA, substantial progress will be made in realizing a transmission “interstate highway” in the SPP

Benefits of Prairie Wind ProjectBenefits of Prairie Wind Project
Enables substantial renewable wind development in western Kansas
Provides substantial economic development benefits to Kansas via jobs for construction of line and wind farms and royalty payments to landowners
Enables broader opportunities for energy markets in Kansas thereby lowering power supply costs
Substantial environmental benefits
Lower voltage lines will be unloaded
Using 765kV technology results in substantially lower losses on the transmission system and improved reliability
