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.


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


230-kV projects currently in design or construction:

  • Southeast Power Link
    SRP will build seven miles of new overhead 230-kilovolt (kV) power lines. A half-mile of the proposed route will be located in Queen Creek and the remainder in Mesa. The project also includes a new 230/69-kV receiving station.
  • Price Road Corridor
    SRP will bring a new double circuit 230-kilovolt (kV) power line from its Knox substation in Chandler to a 230 kV substation site, identified as RS-27, located in the northern section of the Price Road Corridor. The proposed route will run east from the Knox substation, primarily on the south side of the Loop 202, to the north-west portion of the Price Road Corridor. You can learn more on our online open house website.
  • Abel - Pfister - Ball
    Formerly the Abel-Moody 230kV transmission project. 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 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
