September 2017: Final CEC approval
On Sept. 12, 2017, the Arizona Corporation Commission (ACC) granted approval of a Certificate of Environmental Compatibility (CEC) for the Price Road Corridor (PRC) project. The approval, by unanimous vote, is the final step of the application process and enables SRP to move forward with project construction.
Route approved by the ACC:
June-July, 2017: Proposed project for CEC filing and Line Siting Committee approval
On June 13, 2017, SRP filed an application for a CEC with the ACC for 4.8 miles of new overhead transmission line from the Knox substation to a new RS-27 substation, generally along the south side of the Loop 202 and then adjacent to the Gila River Indian Community boundary north of the substation site. The remainder of the project is planned to be underground.
The Arizona Power Plant and Transmission Line Siting Committee held public hearings July 24–25 and recommended approval of the CEC application. The map above, approved by the ACC, was also approved by the Line Siting Committee during this time frame.
June 1, 2017: Second open house
The two maps below were used at our second open house. These maps show a proposed route alternative for the final segment of the new transmission line. This alternative resulted from the agreement between SRP and the City of Chandler. The map on the left displays the entire project path from the Knox substation, along the Loop 202, to the north-west portion of the Price Road Corridor. The map at right displays just the northern portion of the corridor. The routes reflected in these maps were included in the CEC application.
April 2017: First open house
The map below shows the northern portion of the corridor and was used by the public in our first open house meeting to suggest route alternatives to connect the line from the intersection of Price Road and the Loop 202, as it enters the Price Road Corridor, to the site of the new RS-27 substation.
March 2017: Project resumption
The map below highlights the route proposed with SRP's resumption of the project on March 28, 2017. It reflects a reduced load forecast and changes to the City of Chandler's General Plan for the area. The Price Road Corridor 230 kV project consists of a new double circuit 230 kV power line from the Knox substation in Chandler to a 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.
Late 2013
The map below illustrates the status of the public siting process on private lands in late 2013. At that point, SRP concentrated most of its efforts towards pursuing the route alternative on the Gila River Indian Community land (GRIC). We indicated to the public at that time that if SRP was not successful in obtaining the route on the GRIC, we would continue pursuing these alternatives. Now, based on the City of Chandler's August 2016 General Plan and SRP's reduced load forecast, we have removed the Chandler Boulevard alternative as well all single and double circuit 230 kV route alternatives south and east of the RS-27 substation site.
