Connecting the Box Canyon Solar Project to local electric customers

To deliver renewable power to local electric customers, the Box Canyon project is filing an application for a Certificate of Environmental Compatibility (CEC) for a 7-mile, 230-kilovolt (kV) gen-tie transmission line and substation dedicated exclusively to the planned Box Canyon solar generation facility. The gen-tie will connect the new substation, at the Solar facility, to local Pinal County electrical districts and other public power agencies in Arizona at the existing SRP Abel Substation in the Town of Florence.

The addition of the infrastructure will:

  • Facilitate the delivery of renewable power to local electrical customers
  • Invest in new energy infrastructure to increase grid reliability and resiliency
  • Utilize the existing substation infrastructure to deliver renewable power generated at the Box Canyon Solar facility
