Hookdale Substation: 138 kV Electrical Infrastructure in the United States

Hookdale is an operational electrical substation located in the United States, with coordinates 38.785901, -89.319632. The facility operates at a voltage of 138 kV, classifying it as a high-voltage substation critical for transmission and distribution within the regional power grid. As part of the U.S. electrical infrastructure, it supports the reliable delivery of electricity to surrounding communities and industries. 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 transmission-level assets. The 138 kV voltage level is typical for sub-transmission or distribution substations, serving as a link between higher-voltage transmission lines and lower-voltage distribution networks. Such facilities are essential for voltage regulation and load balancing. Hookdale's operational status ensures continued grid connectivity and power quality for the region. Substations like this are integral to maintaining the resilience of the U.S. electrical grid, particularly in areas with varying demand. The facility's location and voltage level contribute to its significance in local and regional energy infrastructure.

The substation is located in a rural or semi-rural area of the United States, where electrical infrastructure supports agricultural and residential loads. The 138 kV voltage level indicates moderate environmental impact, primarily through electromagnetic fields and land use. Substations of this scale typically require cleared land and may affect local wildlife habitats, but they are designed to minimize ecological disruption through standard mitigation practices.
