Overview
Coolidge Substation is an operational electrical substation in the United States, operating at 230 kV. It plays a key role in regional grid stability and power distribution.
Coolidge Substation is an operational electrical substation located in the United States, with coordinates 33.008390, -111.525719. Operating at a voltage of 230 kV, it is classified as a high-voltage substation, critical for transmitting electricity over long distances and ensuring grid reliability. The facility is part of the broader North American power grid, which is regulated by NERC reliability standards and FERC oversight. As a 230 kV substation, Coolidge Substation falls within the typical voltage range for transmission-level infrastructure in the United States. Such facilities are essential for stepping down voltage from extra-high-voltage lines to sub-transmission levels, serving industrial, commercial, and residential loads. The substation likely includes switchgear, transformers, and protection systems compliant with IEEE and NERC standards. Coolidge Substation contributes to the electrical infrastructure of the region by facilitating power flow and maintaining grid stability. Its operational status ensures continued service to local communities and industries. The substation's location in a rural or semi-urban area may influence its design and maintenance practices, with considerations for environmental impact and land use.
Environmental context
The substation is located in a region with a semi-arid climate, typical of the southwestern United States. Its operation involves minimal direct environmental impact, though the surrounding land use and proximity to sensitive habitats may require adherence to environmental regulations. The 230 kV voltage level indicates a significant role in the transmission network, with potential electromagnetic field considerations managed through standard siting practices.
