SouthWestern Power Group, Salt River Project, Tucson Electric Power, Energy Capital Partners and Shell WindEnergy Inc. have entered into an agreement on April 30, 2008, to proceed with the development of the SunZia Southwest Transmission Project (SunZia). When fully developed, the 500-mile SunZia transmission line project will provide an expected 3,000 megawatts of new transmission capacity. The specific alignment will be determined after detailed evaluation of alternative transmission system configurations and routes. Local, state and federal permitting efforts will begin immediately, including an extensive public involvement process, with the first phase expected to initiate commercial operation by 2013.

"In addition to promoting development of wind, solar and geothermal energy production, by creating regional access to these renewable resources, SunZia increases the reliability of the underlying extra high-voltage transmission system in southern New Mexico and southern Arizona", said Tom Wray of SWPG and SunZia's project manager. "SunZia will help create a critical link between existing and planned transmission and generation facilities, while providing new opportunities for the efficient delivery of new resources to meet growing power demands in the southwest."
