Maps and visuals

The route for the electricity transmission line is approximately 732 miles in length, with a typical right-of-way width of 250 feet. Substation/converter stations, approximately 200 acres in size, will be constructed at each terminating point in Wyoming, Utah and Nevada.

These maps show the TWE Project route selected by BLM and WAPA in their respective Records of Decision.

Power line design

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. The AC structures will look very similar to the DC structures, however, they will have three sets of conductor wires instead of two sets.

"Transmission is the biggest barrier to the development of Wyoming's considerable wind energy resources. But not only do we need to build the lines to carry this renewable energy to market, these lines must be 'right-sized' from the start. The key is to get the maximum number of electrons transferred with the least amount of environmental disturbance."

- Wyoming Governor Dave Freudenthal, 2009
