Overview
South Norfolk Substation is an operational electrical substation in the United States, owned and operated by Dominion Energy. It operates at a voltage of 230 kV, serving the grid in the Norfolk, Virginia area.
South Norfolk Substation is an operational electrical substation located in the United States, owned and operated by Dominion Energy. The facility operates at a voltage of 230 kV, placing it in the high-voltage transmission category, which is critical for long-distance power transfer and grid stability. As part of Dominion Energy's infrastructure, it supports the regional electric grid in the Norfolk, Virginia area. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which set reliability standards for the bulk power system. The 230 kV voltage level is typical for transmission substations that interconnect with lower-voltage distribution networks. Dominion Energy, a major utility in the Mid-Atlantic and Southeast, maintains a large portfolio of generation, transmission, and distribution assets. Environmentally, the substation is situated in an urban area near Norfolk, Virginia, a coastal city with a significant industrial and military presence. The facility plays a key role in maintaining grid reliability for the region, including support for critical infrastructure such as naval bases and port facilities. Its operational status ensures continued electricity supply to residential, commercial, and industrial customers in the area.
Environmental context
The South Norfolk Substation is located in an urban coastal environment near Norfolk, Virginia, an area prone to hurricanes and sea-level rise.
