Overview
Ehrenberg Substation is an operational electrical substation in Arizona, United States, owned and operated by Arizona Public Service. It operates at a voltage of 33 kV, serving the local grid.
Ehrenberg 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 power distribution network. With a voltage level of 33 kV, it is classified as a medium-voltage substation, typical for distributing electricity to local communities and industrial areas. The substation operates under the regulatory framework of the United States, which includes reliability standards set by the North American Electric Reliability Corporation (NERC) and oversight by the Federal Energy Regulatory Commission (FERC) for transmission-level assets. While 33 kV is below transmission-level thresholds, the facility must still comply with applicable grid codes and safety standards to ensure stable and reliable power delivery. As part of Arizona Public Service's infrastructure, Ehrenberg Substation contributes to the electrical supply in the region, supporting residential, commercial, and agricultural customers. Its location in a rural area of western Arizona underscores its importance in maintaining grid stability and providing essential electricity services to the surrounding community.
Environmental context
The substation is situated in a rural desert environment in western Arizona, characterized by arid conditions and high solar exposure. The surrounding area is sparsely populated, with land use primarily consisting of agriculture and open desert. The facility's operation involves minimal direct environmental impact, though its role in the grid supports the integration of renewable energy sources, such as solar power, which are prevalent in the region.
