Extra-high voltage power line projects

SRP's Public Involvement department actively pursues constructive interaction with communities to site critical infrastructure.

Public Involvement incorporates technical and educational elements in its outreach efforts to the people, organizations and jurisdictional leaders in each community. The department then works to ensure that SRP project management receives constructive feedback from the communities.

Once a project is sited, Public Involvement remains in contact with the community through construction providing a continuous thread of communication from project start to finish.

These include active 500-kV, 230-kV and 115-kV power line siting and construction projects.

500-kV

There are no 500-kV projects currently in the siting process or under construction.

230-kV

230-kV projects currently in the siting process:

  • Price Road Corridor
    A public process is underway to site new 230-kilovolt (kV) power lines and a new 230-kV substation. These new facilities will provide greater reliability and enhance the overall electric system for customers in south Tempe and Chandler. You can learn more on our online open house website.

230-kV projects currently in design or construction:

  • Abel - Moody
    SRP will build a double-circuit 230-kV transmission line connecting the Abel substation to a previously sited 230/69-kV substation site to serve developing areas in and around Queen Creek. The new transmission line will also connect to a new 230/69-kV substation that was sited as part of this project.

115-kV

115-kV projects currently in design or construction:

  • Superior - Silver King Relocation
    At the request of Resolution Copper Mining, LLC, SRP will relocate approximately one mile of an existing 115-kV line on Resolution's property.

Permitted corridors

See our list of permitted transmission projects that have not yet been constructed.
