SRP resumes transmission project to support growth
The new approach reflects a reduced load forecast and changes in the city of Chandler’s General Plan for the area
Salt River Project is resuming a project to bring needed power lines to support economic development in the Price Road Corridor.
The new approach reflects a reduced load forecast and changes in the city of Chandler’s General Plan for the area.
In response to customer growth, SRP will bring a new double circuit 230-kV power line from its Knox substation in Chandler to a 230kV substation, identified as RS-27, which is located in the northern portion 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. SRP is seeking input on the best location of the line from this area to the RS-27 substation site.
According to John Coggins, SRP’s senior director of power delivery, the new project will have less impact on the surrounding community than previously planned because it will require fewer miles of 230 kV transmission lines and eliminates a second previously proposed substation. He added that the new approach will cost less for SRP customers and be just as reliable.
The project is responsive to changes in the city of Chandler’s 2016 General Plan 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-using facilities such as data centers. These changes decrease the demand for power that SRP forecasts will be needed for the Price Road Corridor in the future.
"SRP’s new Price Road Corridor transmission project will provide the capacity needed to ensure that adequate and reliable energy is available to allow businesses to grow and add jobs in this important commercial corridor," said Coggins.
Following the public process, SRP will apply for a Certificate of Environmental Compatibility (CEC) for the project which will be considered in a hearing before the Arizona Power Plant and Transmission Line Siting Committee. A final decision to approve the CEC for the project will be decided at an open meeting of the Arizona Corporation Commission.
The CEC application for the Knox transmission line to RS-27 will replace an earlier CEC by SRP for new power lines and substations for the Price Road Corridor. The previous application included route alternatives that were dependent on a Gila River Indian Community alternative that was rejected by the Community’s Tribal Council. SRP plans to withdraw that application.
SRP anticipates that the project could come before the ACC for approval this summer.
SRP is a community-based not-for-profit public power utility, serving about 1 million customers in Maricopa and Pinal counties.
