Kino to DeMoss-Petrie 138 Kilovolt Transmission Line

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.

The Arizona Corporation Commission (ACC) must approve the route before the line can be built. In August 2021, TEP filed an application with the ACC for a Certificate of Environmental Compatibility (CEC). To allow ample time for collaboration with the City of Tucson and additional outreach to stakeholders, TEP withdrew its CEC application. TEP anticipates that the line siting hearing to consider its application will be rescheduled for the first quarter of 2023.

TEP will continue to communicate with neighbors and other stakeholders about the project, and public input 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.
