Overview
King's Mill Substation is an operational electrical substation in Virginia, United States, owned by Virginia Electric and Power Company. It operates at 230 kV and 115 kV voltage levels, serving the regional grid.
King's Mill 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, the facility plays a key role in the regional transmission network. The substation handles voltage levels of 230 kV and 115 kV, indicating its function as a step-down or distribution hub within the grid. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for bulk power systems. As part of the PJM Interconnection, the facility must comply with stringent grid stability and cybersecurity requirements. The dual voltage capability suggests it connects high-voltage transmission lines to lower-voltage distribution networks, serving both industrial and residential customers in the area. Located in southeastern Virginia, the substation supports a region with a mix of urban, suburban, and coastal communities. Its proximity to the Atlantic coast and major military installations underscores its importance for critical infrastructure resilience. The facility's operational status and integration into the broader PJM grid contribute to reliable electricity supply for the surrounding area, supporting economic activities and community services.
Environmental context
The substation is situated in a region with a temperate climate, where seasonal storms and hurricanes can pose risks to electrical infrastructure. Its location near coastal areas may require enhanced flood protection and vegetation management to maintain reliability. The facility's voltage levels and grid role influence its environmental footprint, with potential impacts from electromagnetic fields and land use, though modern substations are designed to minimize ecological disturbance.
