The Kansas Corporation Commission (KCC) has approved a stipulation and agreement reached between Prairie Wind Transmission and ITC Great Plains in Phase II of their applications for the right to construct extra-high-capacity 765 kV transmission lines going west from Wichita, Kan., to Spearville, Kan., and south to the Kansas-Oklahoma border. The project comprises the first 765 kV transmission lines west of the Mississippi River.

Under the agreement, Prairie Wind Transmission will be responsible for constructing a new 765 kV/345 kV substation near Wichita, Kan.; a new 765 kV/345-kV substation northeast of Medicine Lodge, Kan., near the new Flat Ridge Wind Farm, which is jointly owned by Westar Energy and BP Alternative; and a 765 kV transmission line to connect the two new substations. Prairie Wind also will be responsible for constructing a 765 kV line south to the Oklahoma border.

ITC Great Plains will be responsible for constructing a 345 kV/138 kV substation next to Prairie Wind's new substation near Medicine Lodge; a new 765 kV/345 kV substation in Comanche County, Kan.; a new 765 kV/345 kV substation near Spearville, Kan.; a new 765 kV line from the Medicine Lodge substation to the Comanche County substation; and a new 765 kV line from the Comanche County substation to the new Spearville substation.

The project will enhance access to lower-cost electric power markets, improve efficiency of the electric grid, improve reliability and enable development of renewable energy.

Prairie Wind Transmission and ITC Great Plains previously had submitted separate proposals to build 765 kV transmission lines from the Wichita area to western Kansas.

Before the project can move forward, Prairie Wind must receive all necessary regulatory and Southwest Power Pool (SPP) approvals, including regional funding. Upon receiving regulatory and SPP approval, Prairie Wind Transmission will proceed with a line siting application at the KCC.

Prairie Wind Transmission is a joint venture between Westar Energy Inc. and Electric Transmission America.
