AZ Power -- Planning for Arizona's Future

Abel-Moody 230kV transmission project

To meet increased electricity demand and growth, SRP plans to construct an approximately 20-mile,double-circuit, 230-kilovolt (kV) transmission line connecting two SRP-owned and previously sited 230/69kV substations. The new transmission line also will connect a new 230/69kV substation that will be sited and built as part of this project.

Arizona Corporation Commission grants CEC

On Dec. 15, 2009 the Arizona Corporation Commission voted unanimously (5-0) to confirm the Certificate of Environmental Compatibility (CEC) for the Abel-Moody 230kV line.

Line Siting Committee recommends CEC

The CEC specifies the placement of the new 230kV line starting near the Moody substation and extending north along the RWCD then south along the Union Pacific Railroad (UPRR), east on Ryan Road then south on Signal Butte Road to the UPRR, then following the UPRR south to the Magma Railroad into the Abel substation. It also identified the site of the new RS-24 substation, northwest of the Meridian and Combs intersection and south of Queen Creek wash.

The Siting Committee reached its decision after eight days of testimony, discussion and debate.

Project need

Existing electrical transmission facilities serving SRP's developing southeast service area, including Queen Creek, Gilbert, southeast Mesa and nearby unincorporated communities, need additional infrastructure to keep pace with current and future electricity demand. The new transmission line has two primary purposes:

  • Provide additional power that, according to projected development plans, will be required in the near future
  • Increase the reliability and performance of the local high-voltage system

Public outreach

In April 2008, SRP and its consultant, Transcon Environmental, began the siting study for the proposed Abel-Moody 230kV Transmission Project.

SRP and Transcon conducted a comprehensive public outreach process. The project team provided briefings to jurisdictional agencies, convened a Jurisdictional Working Group and held several series of open houses for the public.

  • May-June 2008: Stakeholder briefings, Jurisdictional Working Group meetings
  • June 24-25, 2008: Public open house meetings
  • July-August, 2008: Stakeholder briefings, Jurisdictional Working Group meetings
  • Aug. 25-27, 2008: Public open house meetings
  • September-October 2008: Stakeholder briefings, Jurisdictional Working Group meetings
  • Nov. 12-13, 2008: Public open houses
  • Jan. 29, 2009: Public open house

Construction timeline

SRP continues to monitor the load growth in the Queen Creek area. Construction of the double-circuit 230kV line and substation will occur when area growth resumes. Current projections show that the line will not be built in the next five years.
