William Blount Substation - 161 kV Electrical Substation in the United States

William Blount Substation is an operational electrical substation located in the United States. Operating at a voltage of 161 kV, it is classified as a high-voltage substation, typically serving transmission-level functions within the electrical grid. The facility is part of the broader North American power system, which is regulated by NERC reliability standards and FERC oversight for interstate transmission. As a 161 kV substation, it falls within the typical range for sub-transmission or transmission voltage levels, often connecting bulk power systems to local distribution networks. The facility's location in the United States means it operates under stringent reliability requirements, including compliance with NERC Critical Infrastructure Protection (CIP) standards for cybersecurity and physical security. Substations of this voltage class are common across the country, supporting grid resilience and load balancing. The environmental context of this substation is shaped by its role in the electrical infrastructure. Its operation involves electromagnetic fields and potential impacts on local land use, but modern substations are designed with mitigation measures. The facility contributes to the reliability of electricity supply in its region, supporting residential, commercial, and industrial customers. Its location in the United States ensures adherence to environmental regulations such as the National Environmental Policy Act (NEPA) for any expansions or modifications.

The substation operates at 161 kV, a voltage level that requires careful siting to minimize electromagnetic field exposure and visual impact. Its location in the United States subjects it to federal and state environmental regulations, including NEPA reviews for new construction. The facility's role in grid stability means it supports the integration of renewable energy sources, contributing to broader environmental goals.
