As part of our Energy Gateway Transmission Expansion, we are planning to build a high-voltage transmission line, known as Gateway South (Segment F), extending approximately 400 miles from the planned Aeolus Substation in southeastern Wyoming into the Clover Substation near Mona, Utah.
The Sigurd to Red Butte line (Segment G) is a critical piece of our Energy Gateway transmission expansion and is the third segment of the expansion to be built. The 345-kilovolt high-voltage transmission line stretching approximately 170 miles originates at the Sigurd Substation, near Richfield, Utah and extends south to the expanded Red Butte Substation near Central, Utah. The Sigurd to Red Butte project was completed in May 2015.
As part of PacifiCorp’s Energy Gateway Transmission Expansion, the company is planning to build a 500 kV high-voltage transmission line, known as Gateway South (Segment F), extending approximately 400 miles from the planned Aeolus substation in southeastern Wyoming into the Clover substation near Mona, Utah.
This proposed line segment is part of the Gateway South portion of PacifiCorp's transmission expansion project.
