SWAT - Central Arizona Transmission System (CATS)

The Central Arizona Transmission System (CATS) is a task force of the Southwest Area Transmission (SWAT) subregional planning group. The CATS purpose is to serve as a transmission planning forum for identifying long-term local and subregional transmission needs and facilitating reliability in joint planning, development and operation of the transmission system in Central Arizona. The CATS study area is generally defined as the developable land between Phoenix and Tucson, the bulk of it within the Pinal County borders. The task force proposes an open stakeholder process and will follow the SWAT Charter in coordinating and performing these local and subregional planning efforts.
