Overview
Rio Vista Substation is an operational electrical substation in Arizona, United States, owned and operated by Arizona Public Service. It operates at a voltage of 69 kV, serving the local grid.
Rio Vista Substation is an operational electrical substation located in Arizona, United States. Owned and operated by Arizona Public Service, 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 distributing electricity to industrial and residential areas. The substation operates under the regulatory framework of the United States, which includes NERC reliability standards for grid stability and FERC oversight for transmission-level assets. While 69 kV is below the typical threshold for NERC registration, it still adheres to state-level utility regulations and reliability requirements. The facility is part of Arizona Public Service's infrastructure, which serves a large customer base across the state. Rio Vista Substation contributes to the electrical infrastructure of the Phoenix metropolitan area, supporting grid reliability and local energy distribution. Its location in a growing region underscores its importance in meeting increasing electricity demand. The substation's operational status ensures continued service to the community, aligning with sector goals of maintaining a stable and resilient power supply.
Environmental context
The substation is located in the Sonoran Desert region of Arizona, characterized by arid climate and high solar irradiance. The surrounding area includes urban development and natural desert habitats. Electrical infrastructure in this region must consider heat management and wildfire risks. The facility's voltage level and urban location influence its environmental footprint, with typical considerations for electromagnetic fields and land use.
