About the project
SRP has received a request to provide energy for a commercial data center customer on its own private parcel within the Elliot Road Technology Corridor located in Mesa, Arizona. SRP is responsible for ensuring all customers are provided affordable and reliable electrical service.
As part of this project, SRP will build a new customer-dedicated substation (Hartman) and add a line extension of five 69k poles within the existing SRP Transmission Corridor to serve the new substation.
This substation facility converts higher voltage of 69kV to lower voltage 34.5kV by use of one or more transformers. The substation also monitors and protects each circuit and provides operational control to ensure the system is safe, reliable, and maintainable.
The substation will be located on customer's private property west of Signal Butte just north of Elliot Road.
