Overview
SRP Rohrig Substation is an operational electrical substation in Arizona, United States, owned and operated by Salt River Project. It operates at 69 kV, serving the local grid.
SRP Rohrig Substation is an operational electrical substation located in Arizona, United States. Owned and operated by Salt River Project, this facility plays a role in the regional power distribution network. The substation operates at a voltage level of 69 kV, which is typical for sub-transmission or distribution substations in the United States. As part of the Salt River Project system, the substation is subject to NERC reliability standards and FERC regulations for grid stability. The 69 kV voltage level indicates it serves as a distribution substation, stepping down power from higher transmission voltages for local delivery. The facility is located in a suburban area near Phoenix, supporting residential and commercial loads. The substation contributes to the reliability of the electrical grid in the Salt River Valley. Its operational status ensures continued power supply to the surrounding community. The facility is part of a broader network of substations managed by Salt River Project, which serves over one million customers in Arizona.
Environmental context
The substation is located in the Sonoran Desert region of Arizona, characterized by hot summers and mild winters. The facility's design must account for high ambient temperatures and occasional monsoon storms. Its urban-suburban setting means it is integrated into a developed area with existing infrastructure, minimizing additional land disturbance. The 69 kV voltage level suggests it is a distribution substation, which typically has a smaller footprint and lower environmental impact than high-voltage transmission substations.
