What's New

The Record of Decision (ROD) for the Energy Gateway South Transmission Line Project was signed on December 13, 2016, and is now publicly available.  The ROD can be accessed through the Documents tab on the left-hand column of this site.

The BLM published the Final Environmental Impact Statement (EIS) and Proposed Land Use Plan Amendments (LUPA) on May 12, 2016.  The 30-day public protest period ended June 13, 2016.
 
PacifiCorp (doing business as Rocky Mountain Power) a regulated public utility, has filed an application for a right-of-way (ROW) to construct, operate and maintain a 500 kV overhead, alternating current transmission line to cross public and private lands for the Energy Gateway South Transmission Line Project. When completed, the Project would transmit about 1,500 megawatts of electricity generated from renewable and thermal sources at planned facilities in Wyoming.

The project begins in south central Wyoming near Medicine Bow, at the planned Aeolus Substation, and traverses from northeast to southwest across northwestern Colorado to the planned Clover Substation near Mona, Utah.

• 500 kV alternating current overhead transmission line
• 250 foot right-of-way width
• 400+ miles long
• Guyed steel lattice and self-supporting steel lattice towers,
• 140-190 feet in height
• Average tower spans are 1,000 to 1,500 feet apart
  (4-5 structures per mile)
• Alternative routes affect 17 counties in Wyoming, Colorado & Utah
• Scoping meetings were held spring 2011
