Kino to DeMoss-Petrie 138 Kilovolt Transmission Line

Public Hearing Delayed for TEP Transmission Line Project

A public hearing for a proposed Tucson Electric Power (TEP) transmission line in midtown Tucson has been delayed until early next year.

The Arizona Power Plant and Transmission Line Siting Committee’s public hearing for TEP’s proposed Kino-DeMoss Petrie 138-kilovolt (kV) Transmission Line Project, originally scheduled to begin Monday, Sept. 13, has been rescheduled to begin Feb. 7, 2022. That date remains tentative and subject to change at the discretion of the committee’s chairman.

Tucson Electric Power (TEP) is developing plans for a new transmission line that will strengthen electric reliability for customers in central Tucson and help satisfy growing energy needs in our community.

TEP is identifying a route for the Kino to DeMoss-Petrie (Kino-DMP) 138-Kilovolt (kV) Transmission Line, which will connect the Kino Substation to the DeMoss-Petrie Substation and interconnect with the planned Vine Substation.

TEP has identified preliminary routes that could be combined in various ways to form route alternatives. TEP will use public input to identify up to three alternative transmission line routes in its application to the Arizona Corporation Commission (ACC), which must approve the route before the line can be built. After continued analysis and additional input from stakeholders, TEP included Route 5A as an option in its CEC application, which was filed with the ACC in August 2021.

Public outreach remains an important part of TEP’s planning process. TEP encourages neighbors and other stakeholders to share their comments using one of the public participation methods listed below.

Answers to Questions about Underground Electric Lines

Most of TEP's electrical facilities are installed above ground, but some lower-voltage distribution lines are installed underground. To learn more, please review answers to frequently asked questions about the potential underground installation of transmission lines and distribution lines.
