Huffman Substation - 138 kV Electrical Substation in the United States

Huffman Substation is an operational electrical substation located in the United States, with coordinates 36.777280, -80.719338. 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. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), ensuring compliance with reliability standards for bulk power systems. As a 138 kV facility, it is typical of sub-transmission or distribution substations that step down voltage for local distribution networks. Environmentally, the substation's location in a rural area of Virginia minimizes direct impact on urban populations, though its role in grid stability supports reliable electricity supply to surrounding communities. The facility's operational status indicates ongoing contribution to the electrical infrastructure of the region.

The substation is situated in a rural area of Virginia, where the surrounding landscape includes forested and agricultural land. Its operation at 138 kV places it within the sub-transmission voltage class, which typically involves lower environmental footprint compared to extra-high-voltage lines. The facility's presence supports grid reliability for local communities without significant urban density.
