Overview
Hanger Substation is an operational electrical substation owned by Salt River Project in Arizona, United States. It operates at 69 kV, serving the local grid.
Hanger Substation is an electrical substation located in Arizona, United States, and is owned and operated by Salt River Project. The facility operates at a voltage level of 69 kV, which classifies it as a medium-voltage substation typical for distribution and sub-transmission roles within the regional power grid. As part of the Salt River Project, one of the largest public power utilities in the United States, Hanger Substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). The substation likely incorporates standard automation and protection systems compliant with IEEE and NERC standards to ensure grid reliability and safety. The substation plays a critical role in distributing electricity to residential, commercial, and industrial customers in the Phoenix metropolitan area. Its operational status contributes to the stability of the local electrical infrastructure, supporting the growing energy demands of the region.
Environmental context
The substation is located in an arid desert climate typical of central Arizona, where high temperatures and seasonal monsoon storms can affect electrical equipment performance. The surrounding area is predominantly urban and suburban, with proximity to residential and commercial developments. The facility's design likely includes measures to mitigate heat-related stress on transformers and switchgear, as well as protection against dust and occasional flooding.
Frequently asked questions
Hanger Substation is located in Arizona, United States, near the coordinates 33.364390, -111.892772, within the service area of Salt River Project.
Hanger Substation operates at a voltage of 69 kV, which is a common sub-transmission voltage level used for distributing power from higher-voltage transmission lines to local distribution networks.
Hanger Substation is owned and operated by Salt River Project, a major public power utility serving the Phoenix metropolitan area.
Substations in the United States must comply with NERC reliability standards for grid stability and FERC regulations for interstate electricity transmission. Additionally, equipment often follows IEEE and ANSI standards for safety and interoperability.
A 69 kV substation typically serves as a sub-transmission node, stepping down voltage from higher transmission levels (e.g., 230 kV or 500 kV) for distribution to local feeders, or stepping up voltage from generation sources. It is critical for maintaining voltage stability and reliability in the regional grid.
