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 UA North 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.

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.
