Southwest Intertie Project - South

Western is considering whether to provide partial financing in the amount of $354 million for the southern portion of the Southwest Intertie Project. SWIP-South consists of approximately 235 miles of 500-kV transmission line and would extend from Harry Allen Substation near Las Vegas, Nev., northward to the proposed Thirtymile Substation near Ely, Nev. Western is considering partial financing of the project under provisions of our Transmission Infrastructure Program, which was created to implement section 406 of the American Recovery and Reinvestment Act of 2009.

The Department of the Interior, Bureau of Land Management, was the lead agency in the preparation of the Southwest Intertie Project Final Environmental Impact Statement and Proposed Plan Amendment (July 1993). BLM also prepared the Southwest Intertie Project Southern Portion Environmental Assessment (July 2008). Western is proposing to adopt the BLM's previous EIS and EA to meet its obligations under the National Enviromental Policy Act. The BLM's EIS and EA and Western's cover sheet together serve as Western's EIS NEPA documentation for the proposed SWOP-South financing.
