The Phoenix metropolitan area continues to be a fast-growing urban area, with an ever-increasing demand for electricity. We’re developing power lines and siting new facilities to help meet this demand.

project need
Connect the Perryville Substation to the Valencia Substation. Ensure a reliable power source for the future.

project description​
The electric system serving the central Buckeye area is made up of multiple substations and power lines. These substations are located in residential and commercial areas. The loss of any one of the 69kV lines or substations may result in power outages in the area until repairs can be made. Outages are often a result of powerful storms in the area or even vehicle accidents. Adding new facilities will improve reliability and help ensure APS has adequate power available to meet the electrical needs in the area.
To maintain reliable electric service and accommodate future load growth, APS plans to add a new substation near 239th Avenue and Southern​ Avenue. This new substation will require new 69kV power lines to connect into the existing electrical system currently serving the area. These new power lines will connect the new substation with both the Perryville Substation, located at Jackrabbit Trail and Lower Buckeye Road, and the Valencia Substation, located at Miller Road and Maricopa Road. The resulting project will create a continuous 69kV line between the Perryville and Valencia substations, with an interconnection at the new substation.​

project planning​
The new segments of the 69kV power line will be built on steel poles and will be either a single 69kV circuit configuration (three wires per circuit) or a double 69kV circuit configuration (six total wires on the same pole). The new 69kV power lines may be constructed in a new alignment or added in areas where some lines already exist. In most cases the existing facilities would be rebuilt on the new poles to consolidate structures. It is anticipated that any new poles would be approximately 65 feet in height. The line segments would require a right-of-way or easement approximately 30 to 40 feet in width to construct, operate, and maintain the facility. APS plans to have the first new 69kV power line (Valencia segment) in service by approximately late 2018.

In early 2017, APS hired Environmental Planning Group (EPG) to assist in evaluating route alternatives, to assess potential environmental impacts, and to support the public outreach process. Baseline information about land use, visual, biological, cultural, and recreational resources for the area has been collected. This information, along with engineering and construction studies performed by APS, was used to develop preliminary route alternatives within the study area.

When developing route alternatives, APS evaluates many criteria, including: environmental impacts, engineering and construction feasibility, land acquisition timing and costs, regulatory approvals, potential impacts to existing and planned neighborhoods, and input from agencies and the public.
 
 
Initial briefings were held with representatives and officials from the City of Buckeye to inform them of the proposed project, and to solicit input. The public was notified of the project with our first newsletter mailing in March 2017 and a public open house on March 22, 2017. A second newsletter was mailed in July to announce the second public open house that was held August 2, 2017. At these meetings the public learned about the project need, how the siting process is carried out, and provided their input on possible line route locations. Throughout this process we have received numerous comments about the project through the web, mail, email, and by telephone.
 
All comments, input, and data gathered have been analyzed and evaluated and the results were used to identify potential power line routes. These potential routes were further evaluated using the siting criteria mentioned above and several different alternatives were carried forward for public input (see map below).

public input is important​
An important component of this siting process is to gather input from residents, tenants, property owners, and businesses within the study area. APS and EPG have completed a thorough review of all public comments submitted. After consideration of the comments and a more detailed engineering evaluation, APS has selected the final power line routes. A third and final newsletter was mailed to the public and key stakeholders on October 13, 2017. This final newsletter illustrated the selected final power line routes and the anticipated schedule for construction.
Following this second open house, APS and EPG will review all additional public comments submitted. After consideration of the additional comments and a more detailed engineering evaluation, APS will select the final power line routes. A third and final newsletter will be prepared and distributed to the public and key stakeholders. This final newsletter will illustrate the selected final power line routes and the anticipated schedule for construction.​
project updates​
Although the siting process is now complete, this webpage will be maintained with the latest information. Questions can be submitted to an APS Siting Consultant at perryvillevalencia@apsc.com.
