What is SWAT? Southwest Area Transmission (SWAT) is a voluntary and open study group comprised of regulators, governmental entities, transmission users, transmission owners, transmission operators, environmental entities, and other stakeholders. The goal of SWAT is to promote collaborative regional transmission planning in the Desert Southwest. http://www.westconnect.com/planning_swat. php 3

History of SWAT Utilities have always been engaged in regional cooperation to ensure the reliability of the grid (Western Systems Coordinating Council formed 1967). In the mid- grid and encouraged formation of regional transmission groups (Southwest Regional Transmission Association formed 1994). Local voluntary study groups formed in Arizona when the Arizona Corporation Commission began conducting Biennial Transmission Assessments in 2000 (e.g. Southeast Arizona Transmission Study and Central Arizona Transmission Study). Organizations. Many planning groups realigned, but RTOs never became mandatory. (SWRTA merged with WSCC in 2002 to form WECC, while WestConnect prepared to become an RTO in the Southwest) In 2004, CATS expanded its voluntary group to form SWAT. SWAT has coordinated with Sierra Subregional and Colorado Coordinated Planning Groups since 2007 to meet increased FERC regional planning requirements (WestConnect Agreement for Subregional Transmission Planning). SWAT will continue to define its role through the future as regional transmission planning needs change (e.g. FERC Order No. 1000). 4
