Patriot Substation

TEP is building a new 138-kilovolt (kV) substation on the southwest corner of East Escalante and South Kolb roads. The Patriot Substation will help Davis-Monthan AFB meet Department of Defense-mandated energy resiliency directives, replace aging infrastructure and strengthen electric reliability for residential and commercial customers in the area.

The substation, which will connect to the Irvington-East Loop 138 Kilovolt (kV) Transmission Line, is expected to be in service in 2023.
