Vail Substation

TEP is planning for upgrades at a southeast Tucson substation that will improve electric reliability and support our development of a cleaner, greener energy grid.

TEP is seeking approval from the City of Tucson to rezone land adjacent to the Vail Substation, located near Interstate 10 and South Rita Road, to accommodate construction of new 230-kilovolt (kV) substation facilities and potential installation of a battery energy storage system.
