Great Basin Transmission Announces Open Season for the Southwest Intertie Project

ST. LOUIS, MISSOURI (November 6, 2008) – Great Basin Transmission, LLC ("GBT") announces today an Open Season to receive proposals for the purchase of long-term point-to-point transmission rights on the Southwest Intertie Project ("SWIP").  Successful bidders in the Open Season will secure firm transmission rights to support financing of new generation resources and to allow existing generation resources to transport their output to attractive liquid markets in the West.

The SWIP is a proposed above-ground 500 kilovolt ("kV") alternating current ("AC") transmission line stretching over 500 miles between southern Idaho and southern Nevada. As much as 1,850 megawatts ("MW") of north-to-south transmission capacity and 1,850 MW of south-to-north transmission capacity will be available for purchase during the Open Season. 

The SWIP will provide a new energy pathway connecting the existing high voltage transmission infrastructure near Twin Falls, Idaho and the existing systems in northern Nevada and the Las Vegas area. It will provide direct interconnection and/or viable access to multiple transmission providers in the West which may include Arizona Public Service, Idaho Power, Los Angeles Dept. of Water and Power, Nevada Power (NV Energy), PacifiCorp, Salt River Project, Sierra Pacific Power (NV Energy), Southern California Edison, and Western Area Power Administration.

The SWIP is being developed in phases and is well advanced such that the first phase connecting southern Nevada with northern Nevada is expected to begin construction in 2009 and achieve commercial operation as early as 2010. The next phase reaching to southern Idaho is expected to achieve commercial operation as early as 2011.

GBT is developing the SWIP in response to the growing needs of the Desert Southwest and the Northwest. The SWIP will provide economic, environmental and reliability benefits for the West. The SWIP will also provide an important pathway for renewable energy resources to reach major load centers. 

GBT will conduct the Open Season in a transparent and nondiscriminatory manner. Entities wishing to secure long-term point-to-point transmission rights on the SWIP may submit proposals for consideration. To ensure a fair and open process, generation affiliates of GBT will not submit proposals in the Open Season. GBT will hold a conference for potential bidders in Las Vegas on November 18, 2008, to provide a description of the SWIP and key information about the Open Season process. GBT staff will be available at the conference to answer questions and receive feedback from potential bidders. The specific time and location details for the conference will be posted on the SWIP Open Season website.
