Overview
White Stone Substation is an operational electrical substation in Virginia, United States, owned by Virginia Electric and Power Company. It operates at voltages of 115 kV and 13.2 kV, serving the local grid.
White Stone Substation is an electrical substation located in Virginia, United States. Owned by Virginia Electric and Power Company, the facility is operational and plays a role in the regional power distribution network. The substation operates at two voltage levels: 115,000 volts (115 kV) for transmission and 13,200 volts (13.2 kV) for distribution, indicating its function as a step-down substation connecting the high-voltage transmission grid to local distribution systems. As part of the U.S. electrical infrastructure, this 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, including voltage regulation, protection coordination, and maintenance practices. Substations like White Stone are critical nodes in the grid, facilitating power flow and ensuring system stability. The substation's location in Virginia places it within the PJM Interconnection, one of the largest regional transmission organizations in the U.S. Its role in stepping down voltage from transmission to distribution levels supports local communities and industries. The facility's age and specific equipment are not detailed, but typical substations of this scale include switchgear, transformers, and protection systems to ensure safe and reliable operation.
Environmental context
The substation is situated in a rural area of Virginia's Northern Neck region, near the Chesapeake Bay. Its operation involves electromagnetic fields and potential oil containment from transformers, which are managed under environmental regulations. The site's proximity to water bodies requires careful stormwater management and spill prevention measures to protect local ecosystems.
