Harrison Substation

TEP is proposing to build a new 138-kilovolt (kV) substation at the northwest corner of North Harrison Road and East Speedway Boulevard that will help ensure continued reliability and satisfy customers' future energy needs.

The proposed Harrison Substation will provide greater electric capacity to ensure continued reliability for current and future residential and commercial customers in the eastside service area. Three existing substations that serve the area are operating at or above capacity.

The proposed substation will connect to the existing 138-kV transmission line located along the south side of East Speedway Boulevard. The substation would improve electric reliability and reduce the frequency and duration of electrical service outages. The substation also would accommodate anticipated future growth in the area. The need for a substation in the area has been identified in long-term transmission plans filed with the Arizona Corporation Commission.
