Aerospace Research Campus Transmission Project

Tucson Electric Power (TEP) has identified a potential route for a new transmission line that will serve Pima County’s Aerospace Research Campus, supporting economic development and job creation in our community.

The Aerospace Research Campus Transmission Project will link TEP’s existing 138 kilovolt (kV) transmission system to the proposed Franco Wash Switchyard, located south of the Tucson International Airport. This upgrade will support new aerospace development and other supply chain industries planned for the 500-acre business campus with no impact on service reliability for other customers.

Public input is an important part of TEP’s planning process. We encourage neighbors and other stakeholders to share their comments using one of the public participation methods listed below.
