Rocky Mountain Power Inc. has applied to the Nevada Public Utilities Commission for a permit to build a segment of PacifiCorp’s 1,900-mile, $6-billion Energy Gateway Transmission Expansion Project. On May 21, PacifiCorp’s Salt Lake City-based division applied to build 77 miles of 500-kV transmission and ancillary facilities in Clark and Lincoln counties, Nev.
Portland, Ore.-based PacifiCorp’s Energy Gateway, announced in 2007, is envisioned as a network that will branch to the west and southwest from Windstar substation near Casper, Wyo., with north-to-south links between the branches in Utah and a separate segment between Washington and Oregon. The Federal Energy Regulatory Commission in October 2008 approved rate incentives for most of the proposed project.
