Gateway South

With energy use on the rise and electrical demand fast approaching the limits of the existing transmission system, new facilities are needed to meet the growing needs. This growth in demand for electrical energy comes from both new and existing customers. Individually, consumers today are using 26 percent more electricity than they did 20 years ago.

As part of PacifiCorp’s Energy Gateway Transmission Expansion Project, the company is planning to build a high-voltage transmission line project across southern Wyoming, potentially crossing northwest Colorado, through Utah to a point north of Las Vegas, Nevada. This line segment, Gateway South, will be approximately 800 miles long, supplying present and future needs of customers and enhancing electric system reliability throughout the region. In addition, the project will enable delivery of existing and new generating resources, including wind, to more customers.
 
The proposed route for Gateway South, Aeolus to Mona, extends from eastern Wyoming to a hub near Mona, Utah, where it will connect with another segment that continues through southern Utah.
 
The proposed route for Gateway South, Mona to Crystal, is from a new substation that will be built near Mona, Utah, connecting to multiple substations through southwest Utah to a point north of Las Vegas, Nevada.
 
Sigurd to Red Butte, another transmission line that is part of the Gateway South project, will start in Sigurd, Utah, and continue south to the Red Butte Substation north of St. George, Utah.
 
Gateway South maps will be available following Public Scoping in Spring 2010.
 

Project Timeline

  • Public Scoping – August/September 2010
  • Informational Meetings – August/September 2010
  • Environmental Impact Statement – December 2008-2015
  • Estimated line in service for customers – 2017-2019

Public Participation

Public input is a very important part of this process and will be welcomed at all stages of this transmission line development. Public Scoping meetings are expected to be held as part of the environmental review process. The Bureau of Land Management will oversee this process under the National Environmental Policy Act and will host these meetings to collect official public comments on the project for the draft Environmental Impact Statement.
