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. Substations/converter stations will be constructed at interconnection points 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.

In the news

"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."
