TranWest Express Transmission Line

On January 25, 2019, TransWest Express, LLC filed an application for a permit to construct and operate the TransWest Express Transmission Project (TWE Project) in Carbon and Sweetwater Counties.    The TWE Project is a high voltage transmission system that will extend across four states from south-central Wyoming to Southern Nevada.  In Wyoming, the TWE Project will include the Northern Terminal, an associated ground electrode, and a converter station, all in Carbon County near the Town of Sinclair.  In addition, about 92 miles of transmission line will extend west from the Northern Terminal following the I-80 corridor toward the Town of Wamsutter then turn south to the Colorado state line. The project is located on 4,298 acres of private, state and federal land in both Carbon and Sweetwater Counties.  Construction is anticipated to commence in the second quarter of 2020. The transmission line will take approximately 18 months to construct during 2020 and 2021. The Northern Terminal will be constructed in two stages. Stage I will take approximately 3 years to construct between 2020 and 2022. Stage II construction will take about 3 years to complete (2023 to 2025) but may commence 3 or more years after the completion of Stage I construction dependent on future demand and market conditions.  Construction manpower is anticipated to peak at 243 workers in October 2020 and 168 workers in June 2021.
