The proposed route for the 600 kilovolt direct-current transmission line is approximately 725 miles in length, with a typical right-of-way width of 250 feet. Two substation/converter stations, approximately 200 acres in size, will be constructed at each terminating point. In addition to the proposed route, the right-of-way application submitted to the Bureau of Land Management by TransWest Express LLC includes alternative routes. The ROW application also provides for the TWE Project to be configured to allow for a potential interconnection with the IPP transmission system near Delta, Utah.
Along the route, transmission structure heights may vary from 100 feet to 180 feet depending upon structure type, terrain, span and line crossings. The span between structures may vary from 900 to 1,500 feet.

"A robust transmission grid provides consumers with access to lower-cost electricity. On a severely constrained transmission grid… consumers are forced to rely on local power plants even though plants in other regions can produce power more efficiently and at lower cost."
