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 number of peer-reviewed studies have documented that the aggregate output of wind and solar plants spread over a large geographic area is much less variable than the output of plants clustered into a small area. Thus, a more robust grid can significantly reduce the cost of integrating wind and solar power with the grid by allowing larger power flows between regions as well as making it possible to access renewable resources from a greater diversity of areas."
