Electric Transmission America, a joint venture of subsidiaries of American Electric Power and MidAmerican Energy Holdings Co., has formed a joint venture company with Westar Energy Inc. to build and own new electric transmission assets in Kansas.
The ETA and Westar joint venture, named Prairie Wind Transmission LLC, is proposing to build approximately 230 miles of extra-high voltage 765-kilovolt transmission facilities extending from Wichita, Kan., west to a substation northeast of Dodge City, Kan., and then south to the Kansas border from Medicine Lodge, Kan. The project will provide enhanced electricity transport in Kansas and support expansion of renewable electricity generation in the region.
Southwest Power Pool’s estimated costs for the project are approximately $600 million; however, final costs will be dependent on the routing of the line, equipment and commodity costs. Anticipated completion would be in 2013. AEP’s ownership share of the joint venture will be 25 percent.
