Price Road Corridor overview

Thank you for taking the time to learn more about SRP's Price Road Corridor 230 kV Transmission Line Project. The project is critical in enhancing reliability of our electric system and supporting the economic growth along the Price Road Corridor in Chandler.

Use the online open house to explore the major topics of the project. We encourage you to move in order from left to right through each topic. To submit questions, please use the online form on our contact page.

SRP's mission is to deliver high-value electricity and water for the benefit of our customers and the communities we serve. Delivering on this promise means addressing the needs of future customers today. Dr. A.J. Chandler shared in this vision when he sat on SRP's first board in 1903, collaborating to bring about the prosperous region that would later become the City of Chandler. With growth on the horizon for the Price Road Corridor, SRP is as committed today as it was more than 100 years ago to meeting the needs of our customers.

Project overview

SRP is planning to construct new electrical infrastructure to enhance reliability for current customers and support new and expanding businesses in the Price Corridor — a five-square-mile area in Chandler. The area is a thriving employment center and innovation hub for advanced business services, life sciences, aerospace, high technology research and manufacturing.

The project consists of a new double-circuit 230 kV power line from the Knox substation in Chandler to a new 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.

The Knox-to-RS-27 line will have less impact to the surrounding community than previously planned because it will require fewer miles of 230 kV transmission lines and eliminates a second previously proposed substation. The new approach will be more cost-effective for SRP customers and just as reliable.

The reduced scope of the project is responsive to changes in the City of Chandler's 2016 General Plan Document is a PDF that modify land use criteria to allow for office buildings that use less energy and reflect the City Council's desire to emphasize office space and employment rather than other higher energy-use facilities such as data centers. These changes decreased the load that SRP forecasts will be needed for the Price Road Corridor in the future.

Project milestones

On April 25, 2017, SRP held the first of its public open house meetings to gather comments on proposed routes that reflect the project's reduced scope and to review route alternatives. These routes were identified in an earlier public process to connect the Knox substation, located north of Pecos Road west of 56th Street, with the new RS-17 230 kV substation on SRP property at the intersection of Germann and Price roads, adjacent to Gila River Indian Community land. This site was identified for the future substation during an earlier public process.

SRP held the second project open house on June 1, 2017. View route maps presented on June 1 and maps from previous open house meetings.

SRP and the City of Chandler reached an agreement on a proposed route alternative for the final segment of the new transmission line. Portions of the route will be constructed underground with the City of Chandler paying the difference between building the line overhead — SRP's standard — and the added cost of putting them underground.

Next steps

On June 13, 2017, SRP filed an application for a Certificate of Environmental Compatibility (CEC) with the Arizona Corporation Commission (ACC) for a new 4.8-mile line from the Knox substation to a new RS-27 substation.

With the filing of the CEC, SRP's public process is complete. The ACC is conducting a public process to address the application. The Arizona Power Plant and Transmission Line Siting Committee held hearings July 24–25 and recommended approval of the CEC application.

The final decision to confirm the CEC will be decided at an open meeting of the Arizona Corporation Commission. Agendas are typically posted one week prior to the meeting date on the ACC website.
