Summary
Contractors told the commission they completed major grading at the Desert Mountain substation (285,000 cu yd excavated; five structure pads complete) and expect a lighter 2026 construction year with commissioning and energization currently estimated for 2030–2031.
Contractors with the TransWest Express project updated the Millard County Commission on preconstruction and grading work at the Desert Mountain substation and terminal pad, reporting substantial earthwork completed this season and outlining the near‑term schedule.
Monica Ellis of the Barnard Wilson joint venture and TransWest staff described the grading metrics: 285,000 cubic yards excavated, 282,000 cubic yards replaced and compacted, 70,000 cubic yards of aggregate imported and about 4,600 cubic yards excavated for the access road. Five structure pads for towers and the terminal were completed, and contractors said they expect substantial grading completion by the end of the year. Safety metrics cited included zero reportable incidents for the season.
Contractors said 2026 will include punch‑list items, seeding and stabilization work and lighter construction activity at the terminal; tower erection and line construction were not expected during the coming grading season. The project team reported an energization and commissioning window targeted around 2030–2031, subject to subsequent construction phases and approvals. Commissioners asked about workforce and local hiring; contractors said they are coordinating with Snow College and local training programs to align workforce pipelines and anticipate several hundred positions tied to the project in coming years.
