Hawes Substation - 69 kV Electrical Substation in the United States

Hawes Substation is an operational electrical substation located in the United States, with coordinates 31.511751, -110.254694. The facility operates at a voltage of 69 kV, placing it in the medium-voltage range typical for distribution-level substations that step down power from higher transmission voltages for local delivery. As a substation in the United States, Hawes Substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) reliability standards and Federal Energy Regulatory Commission (FERC) oversight for transmission-level assets. The 69 kV voltage level is commonly used for sub-transmission or distribution, and the facility likely includes switchgear, transformers, and protection systems compliant with standards such as IEEE C37. The substation's location in a rural area near Sierra Vista, Arizona, suggests it serves local communities and possibly industrial or military installations. The environmental context of Hawes Substation includes its placement in a semi-arid region with low population density, reducing direct human exposure but requiring robust insulation and cooling systems to handle temperature extremes. The substation's role in grid stability is critical for maintaining reliable power supply to the surrounding area, and its operational status indicates ongoing maintenance and compliance with NERC reliability standards.

Hawes Substation is situated in a semi-arid region of the southwestern United States, characterized by low rainfall and high temperatures. The facility's 69 kV voltage level and rural location reduce its environmental footprint compared to urban substations, but it still requires measures to manage heat dissipation and prevent wildlife interference. The substation's operation supports local grid stability, which is essential for the region's growing population and economic activities.
