Overview
Chino Valley Substation is an operational electrical substation in Arizona, United States, owned and operated by Arizona Public Service. It operates at 69 kV, serving the local grid.
Chino Valley Substation is an operational electrical substation located in Arizona, United States. Owned and operated by Arizona Public Service, the facility plays a role in the regional transmission and distribution network. The substation operates at a voltage level of 69 kV, which is typical for sub-transmission or distribution-level infrastructure in the United States. As part of the Arizona Public Service system, Chino Valley Substation operates under the regulatory framework of the Federal Energy Regulatory Commission (FERC) and adheres to North American Electric Reliability Corporation (NERC) reliability standards. These standards ensure grid stability and security for transmission-level assets. The 69 kV voltage class is commonly used for local distribution and industrial supply, connecting higher-voltage transmission lines to end users. The substation's location in rural Arizona supports the electrical infrastructure for the surrounding community and regional grid. Its operational status contributes to the reliability of electricity supply in the area, serving residential, commercial, and agricultural loads. The facility is part of a broader network that maintains power quality and system resilience.
Environmental context
The substation is situated in a semi-arid region of Arizona, where high summer temperatures and low humidity can affect equipment performance and maintenance cycles. The surrounding area is characterized by open rangeland and low-density development, reducing the risk of vegetation-related outages but increasing exposure to dust and wildlife. The 69 kV voltage level indicates a moderate scale of infrastructure, with typical environmental considerations including electromagnetic field management and oil containment for transformers.
Frequently asked questions
