Overview
McCormick 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.
McCormick 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 of 69 kV, which is typical for sub-transmission or distribution-level infrastructure. As part of the Arizona Public Service system, McCormick Substation adheres to North American Electric Reliability Corporation (NERC) reliability standards and Federal Energy Regulatory Commission (FERC) regulations for grid stability. The 69 kV voltage level indicates a medium-voltage substation that likely serves local distribution needs, connecting higher-voltage transmission lines to lower-voltage distribution feeders. The substation's location in Arizona places it within a region experiencing growing electricity demand due to population growth and economic development. Its operational status ensures continued support for residential, commercial, and industrial customers in the area. The facility contributes to grid resilience by providing voltage regulation and load balancing within the APS network.
Environmental context
The substation is situated in an urban or suburban area of Arizona, where land use is primarily developed. Electrical infrastructure like this substation has a localized environmental footprint, including electromagnetic fields and potential impacts on wildlife from vegetation management. The 69 kV voltage level is typical for distribution substations, which are less visually intrusive than high-voltage transmission facilities. The surrounding environment likely includes residential or commercial zones, with standard mitigation measures for noise and visual impact.
