Benefits of the Southwest Intertie Project-North (SWIP North)
Prepared for Great Basin Transmission, LLC
The Southwest Intertie Project-North (SWIP North) is a planned 275 mile 500 kV alternating current (AC) transmission line from the Midpoint substation in southern Idaho to the Robinson Summit substation in central Nevada. The addition of SWIP North (in conjunction with the recently completed One Nevada Line and CAISO-approved Harry Allen to Eldorado project) will create a major new transmission path that runs parallel to the existing constrained transmission corridors between the northwestern and southwestern portions of the Western Electricity Coordinating Council (WECC) region and connects low-cost renewable-generation areas in Wyoming to markets in California, Nevada, and Arizona.
