Overview
Sligo Substation is an operational electrical substation in Virginia, United States, owned by Virginia Electric & Power Company. It operates at voltages of 230 kV, 34.5 kV, and 13.2 kV, serving the regional power grid.
Sligo Substation is an operational electrical substation located in Virginia, United States. Owned by Virginia Electric & Power Company, a subsidiary of Dominion Energy, the facility plays a key role in the regional transmission and distribution network. The substation handles multiple voltage levels, including 230 kV for high-voltage transmission and lower voltages for local distribution. The substation operates under the regulatory framework of the U.S. Federal Energy Regulatory Commission (FERC) and adheres to North American Electric Reliability Corporation (NERC) reliability standards. As part of the PJM Interconnection, the facility contributes to grid stability and reliability across the mid-Atlantic region. The 230 kV voltage level indicates its importance in bulk power transmission. Located in a rural area of northeastern North Carolina, near the Virginia border, the substation supports local electricity distribution and grid interconnection. Its operational status and ownership by a major utility underscore its role in maintaining reliable power supply to surrounding communities and industries.
Environmental context
The substation is situated in a rural area with mixed agricultural and forested land use. Its operation involves electromagnetic fields and potential impacts on local wildlife, though modern substations are designed to minimize ecological disruption. The facility's voltage levels and grid role contribute to regional energy reliability, supporting both residential and industrial loads.
