Electric Transmission America (ETA) has signed two separate memorandums of understanding (MoUs) with Exelon and MidAmerican Energy Holdings (MEHC) to develop two 765kV, extra high-voltage transmission projects in the Midwest US.

The two projects include a series of transmission lines that will extend from the Indiana/Ohio border into Iowa and will establish part of the infrastructure needed to strengthen the Midwest transmission grid and provide Midwest states with access to additional sources of energy.

ETA has signed an MoU with Exelon to jointly develop 420 miles of 765kV transmission lines that will extend from the Indiana/Ohio border west across Indiana into Henry County, Illinois.

ETA will develop 104 miles of the proposed transmission lines located in Indiana, and Exelon subsidiary Commonwealth Edison will build the Illinois portion of the project.

ETA signed a second MoU with MEHC to jointly develop another 180 miles of 765kV transmission lines that will extend from the terminus of the first project in Henry County, Illinois, to Louisa County, Iowa, and then to Buchanan County, Iowa.

The projects are the first commercial transmission proposals supported by the recently completed SMARTransmission study, an effort to develop a conceptual 20-year transmission plan for the Midwest.

ETA is a joint venture between subsidiaries of American Electric Power and MEHC to build and own electric transmission assets.
