Overview
Jones Substation is an operational electrical substation owned by Salt River Project in the United States. It operates at 69 kV, serving the local grid in Arizona.
Jones Substation is an operational electrical substation located in the United States, owned and operated by Salt River Project. The facility operates at a voltage of 69 kV, placing it in the sub-transmission class typical for regional distribution networks. As part of Salt River Project's infrastructure, it supports electricity delivery in the Phoenix metropolitan area. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which set reliability standards for the bulk power system. With a voltage of 69 kV, Jones Substation is a key node in the local distribution network, stepping down power from higher transmission voltages for end users. Environmentally, the substation is located in an urbanized area of Arizona, where grid reliability is critical for residential and commercial customers. Its role in the Salt River Project system contributes to the region's energy resilience, supporting growing demand in the Phoenix area. The facility's operational status ensures continued service to the community.
Environmental context
Jones Substation is situated in an urban setting in Arizona, where high summer temperatures drive peak electricity demand for air conditioning. The facility's 69 kV voltage level is typical for sub-transmission networks that balance reliability with environmental footprint. Its location in a developed area minimizes land-use impacts while supporting grid stability for surrounding communities.
