McAlmont Substation - Operational 115 kV Substation in the United States

McAlmont Substation is an operational electrical substation located in the United States, with coordinates 34.800511, -92.188796. The facility operates at a voltage level of 115 kV, classifying it as a medium-voltage substation within the US electrical infrastructure. As a substation, it serves as a node in the transmission and distribution network, stepping down voltage for local distribution or interconnecting transmission lines. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for the bulk power system. In the United States, substations like McAlmont are critical for maintaining grid stability and are subject to NERC's Critical Infrastructure Protection (CIP) standards. The 115 kV voltage level is typical for sub-transmission or distribution substations, often serving industrial or urban areas. McAlmont Substation contributes to the electrical infrastructure of its region by facilitating reliable power delivery. Its operational status indicates ongoing service to the grid, supporting local communities and industries. The substation's location in the United States places it within one of the world's largest interconnected power systems, where aging infrastructure and increasing demand pose ongoing challenges for grid operators.

The substation is located in a region with a temperate climate, where seasonal weather variations can impact grid operations. The 115 kV voltage level suggests it may serve urban or suburban areas, where electromagnetic fields and land use are typical environmental considerations. Substations are generally designed with containment measures for potential oil leaks from transformers, and their operation is regulated to minimize environmental impact.
