Mine Road Substation - Virginia Electrical Substation | United States

Mine Road Substation is an operational electrical substation located in Virginia, United States. Owned and operated by Virginia Electric and Power Company, a subsidiary of Dominion Energy, this facility plays a key role in the regional power grid. The substation handles voltage levels of 230 kV and 34.5 kV, indicating its function in both high-voltage transmission and lower-voltage distribution. As part of the U.S. electrical infrastructure, Mine Road 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 for the bulk power system, ensuring stable and secure electricity delivery. The substation's dual voltage levels suggest it serves as a critical node for stepping down power from transmission lines to local distribution networks. The substation's location in Virginia places it within the PJM Interconnection, one of the largest regional transmission organizations in the U.S. This context underscores its importance in maintaining grid stability and supporting the growing energy demands of the region. The facility's operational status and ownership by a major utility highlight its role in delivering reliable electricity to residential, commercial, and industrial customers.

The substation is situated in a region with a mix of urban and rural areas, where electrical infrastructure must balance reliability with environmental considerations. Voltage levels of 230 kV and 34.5 kV indicate a facility that connects high-voltage transmission lines to local distribution, potentially impacting land use and wildlife corridors. Standard practices such as vegetation management and oil containment for transformers help mitigate environmental risks.
