Big Level Substation - 69 kV Electrical Substation in the United States

Big Level Substation is an operational electrical substation located in the United States, with coordinates approximately 30.82°N, -89.05°W. The facility operates at a voltage of 69 kV, which classifies it as a medium-voltage substation typically used for subtransmission or distribution within the electrical grid. As a substation in the United States, Big Level Substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These bodies enforce reliability standards and oversee transmission-level assets. The 69 kV voltage level is common for local distribution networks, connecting bulk power systems to end users. The substation's location in a rural area of Mississippi suggests it serves a smaller community or industrial load. Its operational status indicates ongoing contribution to grid reliability, supporting the local electrical infrastructure and ensuring stable power delivery to surrounding areas.

The substation is situated in a rural area of southern Mississippi, characterized by pine forests and wetlands. The local environment may be sensitive to electromagnetic fields and habitat fragmentation, though substations typically have a small footprint. The 69 kV voltage level poses minimal environmental risk compared to higher-voltage transmission lines, and standard mitigation measures are likely in place to manage any ecological impacts.
