On April 11, 2023, the Bureau of Land Management (BLM) gave final approval, allowing for construction to begin on the TransWest Express transmission project. The BLM started reviewing the project in 2008.[1] The $3 billion transmission project is designed to deliver 3,000 MW of onshore wind generation from Wyoming to California and the Southwest. The 732-mile, bi-directional TransWest Express project is slated to run from a 600-turbine wind farm in Wyoming’s Carbon County to the Eldorado substation in southern Nevada in three segments. The project includes a 3,000-MW direct current (DC) segment between Wyoming and Utah and two 1,500-MW alternating current (AC) segments from Utah to the south of Las Vegas, NV. The project is being developed by TransWest Express LLC, a subsidiary of the Anschutz Corp. TransWest expects the first stage of its project will be completed in 2027. The full 3,000 MW line is expected to be completed by the end of 2028.
