High-tech Interconnect Project (HIP)
About the project
On December 16, 2021, The Arizona Corporation Commission (ACC) voted unanimously to approve a Certificate of Environmental Compatibility (CEC) for the High-Tech Interconnection Project (HIP). Construction began in January 2022 on a new 230-kV substation on Intel’s campus, as well as new 230-kV transmission lines connecting the campus to two existing substations. See details.
SRP worked with the City of Chandler and Intel on the High-Tech Interconnect Project (HIP). The transmission project will provide reliable power to the recently announced $20 billion expansion of Intel’s Chandler campus. The Intel expansion is reported to be the largest private investment in Arizona's history and will be a major economic boost for Chandler, the region and the state, providing thousands of new high-paying jobs. Read press release.
SRP worked with the City of Chandler to meet the City’s preference to underground a significant portion of the transmission line, address conflicts with existing underground utilities, and ensure technical feasibility of the underground segments. The remaining overhead segments are located within areas that already have overhead transmission facilities or are commercial in nature. The underground portion of the route was approved between SRP and the City of Chandler, with the City paying for the incremental cost of undergrounding.
The Intel expansion will require SRP to build a new 230-kilovolt (kV) substation on Intel’s campus as well as new 230 kV transmission lines connecting the campus to two existing substations.
Overhead line: SRP is constructing a new 230 kV line to serve the Intel campus. The approximately 3-mile line will run along Old Price Road and onto the Intel property (see map below). SRP crews installed the foundations and poles, and line crews are in the process of pulling new conductor.
The 230 kV line will require approximately thirty-nine (39) tubular steel structures over the 3-mile line. The structures range from 90 to 180 feet tall.
Underground line: SRP is constructing a new 230 kV underground line to serve the Intel campus. The 230 kV underground line will be installed on the Intel campus and Chaparral Way. SRP hired a contractor to install the 230 kV underground line.
This project is now online.
