Stephenson Substation - 138 kV Electrical Substation in the United States

Stephenson Substation is an operational electrical substation located in the United States, owned and operated by The Potomac Edison Company. The facility operates at a voltage of 138 kV, classifying it as a transmission-level substation that plays a role in the regional power grid. The substation operates under the regulatory framework of the United States, which includes reliability standards set by the North American Electric Reliability Corporation (NERC) and oversight by the Federal Energy Regulatory Commission (FERC) for transmission assets. As a 138 kV substation, it is typical of medium-voltage transmission infrastructure that supports distribution to local communities. The facility's operational status and voltage level indicate its importance in maintaining grid stability and power delivery in the region. Substations like Stephenson are critical nodes in the electrical infrastructure, enabling voltage transformation and switching functions to ensure reliable electricity supply to residential, commercial, and industrial customers.

The substation is located in a rural area of Virginia, near Winchester, with surrounding land uses including agriculture and low-density residential. The 138 kV voltage level suggests it serves as a distribution substation, connecting transmission lines to local distribution networks. Its location in a rural setting may reduce direct environmental impacts compared to urban substations, but it still requires vegetation management and electromagnetic field considerations typical of such infrastructure.
