Energy Gateway South Transmission Project
PacifiCorp
Delivering Electricity from New Generating Resources in Carbon County
PacifiCorp's Gateway South Transmission Project is a 416 mile, single-circuit 500-kilovolt (kV), overhead, alternating-current transmission line, beginning near Medicine Bow, Carbon County, Wyoming. The high-voltage transmission line is part of part of PacifiCorp’s Energy Gateway transmission expansion project and will extend south and west to the Clover Substation near Mona, Juab County, Utah. The Energy Gateway transmission expansion will:
- Serve the growing needs of customers while improving the reliability of its overall transmission system
- Ensure the system is adequate and capable of meeting future customer load growth
- Provide more flexibility to move energy resources where they are needed and to maintainlow-cost delivery and service reliability
- Help shape customers’ future rates instead of leaving it largely exposed to market price volatility and availability of outside resources
