Overview
Sherman Street Substation is an operational electrical substation in Phoenix, Arizona, owned and operated by Arizona Public Service. It operates at 69 kV, serving the local grid.
Sherman Street Substation is an operational electrical substation located in Phoenix, Arizona, United States. Owned and operated by Arizona Public Service (APS), the facility plays a key role in the regional power distribution network. With a voltage level of 69 kV, it is classified as a medium-voltage substation, typical for urban distribution systems. 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. As part of APS's infrastructure, it adheres to NERC's Critical Infrastructure Protection (CIP) standards and contributes to grid stability in the Phoenix metropolitan area. The 69 kV voltage level is common for sub-transmission and distribution, linking higher-voltage transmission lines to local distribution networks. Environmentally, the substation's urban location in Phoenix means it supports a dense population center with high electricity demand, particularly during peak summer cooling periods. Its role in the grid is critical for maintaining reliable power supply to residential, commercial, and industrial customers. The facility's operational status ensures continued service, and its integration with APS's broader system enhances grid resilience.
Environmental context
Located in the urban environment of Phoenix, Arizona, Sherman Street Substation operates in a region characterized by high summer temperatures and significant air conditioning demand. The substation's 69 kV voltage level is typical for distribution networks, and its urban setting means it is subject to local environmental regulations regarding noise, electromagnetic fields, and stormwater management. The facility's role in the grid is critical for meeting peak load demands and maintaining system stability.
