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.              
​Arizona Public Service Company (APS) is in the early stages of determining a location for a new 69 kilovolt (kV) electric substation in downtown Phoenix.
Voltage: 69/12kV
Estimated completion date: Site location 2018, substation complete 2021
Location: Downtown Phoenix
project need
Ensure reliable and adequate power for the vibrant and growing downtown Phoenix community.
project description
The electric system serving downtown Phoenix 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 vibrant and growing downtown area.
To maintain reliable electric service and accommodate future load growth, APS plans to add a few new substations in the downtown area over the next several years. APS’s initial and more immediate need is to acquire a one-acre property for a new substation in the area roughly defined as 7th Street to Central Ave, Fillmore Street to Moreland Street. This new substation will require new 69 kV power lines to connect into the existing electrical system currently serving the area. These power lines will connect the new substation to the existing 69 kV overhead power lines along Roosevelt Street.
your input is important to aps

An important component of this process is to gather input from residents, tenants, property owners, businesses, and community organizations within the study area. Three open houses have been held to allow members of the public and all interested parties to join APS, talk one-on-one about the need and benefits of the project, and provide input on potential sites for the project as well as architectural design elements.​

Input gathered at the first set of meetings is currently being evaluated and analyzed.  APS will be scheduling another open house, hopefully to be held in June, to share information the latest information and discuss remaining alternatives and receive further input and feedback.  APS is continuing to meet with local jurisdictional leaders and affected stakeholders to determine if other alternatives might be available. We anticipate having a final site selection towards the end of 2018​

public open house events
Open houses were held on February 27th, March 9th and March 15th.  APS plans to hold its next public open house sometime in June.  Local residents and stakeholders will be notified by mail and please check this web page for further information once that meeting is scheduled​.

project updates
Throughout the planning process, this webpage will be maintained with the latest information.  Question or comments on the Project can be directed to Kendra Lee, APS Program Manager at 602-371-7872 or by email at We look forward to your feedback.

project need
Build four new substations and interconnecting 69kV power lines

project description​
Arizona Public Service Company (APS) is developing a plan to build new energy facilities to better serve the growing population in the northern region of Peoria. APS continually monitors its electrical system and, when necessary, adds or upgrades facilities. These improvements enhance reliability and help ensure that an adequate supply of electric power is available to customers.
To maintain reliable electric service and accommodate future load growth, APS has determined the need to build new substations and associated 69 kilovolt (kV) power lines in the North Peoria region, as shown within the study area on the map below. These facilities would generally be located within or adjacent to the new Vistancia North, Lake Pleasant Heights, and Saddleback Heights developments. A network of 69kV power lines would be constructed to bring power from existing substations and power lines near the east side of the study area and provide possible connections for new sources of power near the northwest side of the study area.
A total of four new substations and interconnecting 69kV power lines are included in this siting process. APS anticipates the first substation (Substation W03) and related 69kV lines to be in service in 2021, located near the Vistancia North and Lake Pleasant Heights developments (see Phase 1, Substation W03 Siting area on the map below). Although the remaining three substations and interconnecting lines are part of this siting effort, it is anticipated that these facilities would not need to be constructed for 5 to 10 (or more) years, based on current housing development projections. ​

​project planning
It is anticipated that the new segments of the 69kV power lines would be built on steel poles, with either a single 69kV circuit configuration or a double 69kV circuit configuration (three wires per circuit). The new 69kV power lines may be constructed in a new alignment or added in areas where lines already exist. In most cases, if there are existing facilities they 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 40 to 60 feet in width to construct, operate, and maintain the facilities.

siting process

APS has hired Environmental Planning Group (EPG) to assist in evaluating substation sites and 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 will be collected. This information will be used to develop preliminary power line route and substation location alternatives within the study area.
When developing 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, developers and the public. The work completed thus far has included initial data collection of existing and planned land uses.
Initial briefings were held with representatives and officials from local, state, and federal agencies, including the City of Peoria, to inform them of the proposed project, and to solicit input. The public was notified of the project with our first newsletter mailing in April 2018 and the first set of public open houses was held on May 3rd and 8th, 2018. Those who attended either open house learned about the project need, how the siting process is carried out, had the opportunity to ask questions and speak about concerns, and were able to provide input on potential line route locations.

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 are currently reviewing comments and input received via email, postal mail, project web page, voice messages, and at the open houses. These comments as well as an evaluation of environmental factors, engineering and constructability, and other data will help to develop the preliminary alternative power line routes and substation locations.
APS will prepare and distribute a second newsletter to the public announcing project updates and notifying a second round of open houses, expected to be held in late summer of 2018. Preliminary alternative routes and substation locations will be presented at the open houses, and the opportunity for further public comment and input will be available at that time.
