Sigurd to Red Butte No. 2 345kV Transmission Project

PROJECT DESCRIPTION

PacifiCorp, doing business as Rocky Mountain Power (RMP) has filed an application for a right-of-way to construct and operate a 345 kV overhead transmission line to cross public lands (both BLM and the Forest Service) for the Sigurd to Red Butte No. 2 - 345 kV Transmission Project (Project).  The Project would provide about 600 megawatts of electrical capacity to respond to anticipated load growth in southwestern Utah.  This line would connect the Sigurd substation, located approximately six miles northeast of Richfield in Sevier County, Utah to the Red Butte substation, located southwest of the town of Central in Washington County, Utah.    Project details include:

  • 345 kV overhead transmission line
  • EIS being prepared
  • Approximatly 170 miles long
  • Typical H-frame steel towers
  • Towers 80 to 140 feet in height
  • Towers 800—to 1,200 feet apart
  • Agency preferred route could affect land in Sevier, Millard, Beaver, Iron, and Washington Counties. 
  • A geotechnical right-of-way application for RMP to gather geotechnical information to support the Project was filed in September 2009.  A separate EA was prepared for this short-term right-of-way application.  The geotechnical investigation is required to characterize the surface and sub-surface conditions along the proposed routes and to provide information necessary for the engineering design for the transmission line towers.

Announcements

Officials from the Bureau of Land Management (BLM) and U.S. Forest Service have signed Records of Decision (ROD) approving a right-of-way across federal land for the Sigurd to Red Butte No. 2 – 345-Kilovolt Transmission Line Project.   In response to anticipated load growth in southwestern Utah, the project will provide approximately 600 megawatts of electrical capacity—enough energy to power 584,000 American homes—upon completion. In support of the Obama administration's all-of-the-above energy strategy, this transmission line could provide clean wind energy projects in Utah with transmission capacity in the future.  Through construction, the project is also expected to boost the local economy by creating up to 255 jobs.

The signing of the RODs for this project will allow Pacificorp (doing business as Rocky Mountain Power) to construct, operate, and maintain a single-circuit, alternating-current, 345-kV overhead transmission line.  The transmission line would run approximately 170 miles from the existing Sigurd Substation near Richfield, Utah to the existing Red Butte Substation in Washington County, Utah.  The requested right-of-way width for construction and operation of the line on Federal lands is 150 feet.
