Overview
Tanners Point Terminal Station is an operational electrical substation in Virginia, United States, operated by Virginia Electric and Power Company. It operates at 230 kV, serving as a key node in the regional transmission grid.
Tanners Point Terminal Station is an operational electrical substation located in Virginia, United States. Owned and operated by Virginia Electric and Power Company (a Dominion Energy subsidiary), this facility plays a critical role in the regional high-voltage transmission network. The substation operates at 230 kV, a standard voltage level for bulk power transmission, indicating its importance in connecting generation sources to load centers. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). As part of the PJM Interconnection, the facility must comply with mandatory reliability standards, including those for voltage support, system protection, and cybersecurity. The 230 kV voltage class is typical for large substations that serve as major interconnection points within the Eastern Interconnection. Located near the Hampton Roads metropolitan area, Tanners Point Terminal Station supports the electrical infrastructure for a region with significant industrial, military, and residential demand. Its strategic position helps maintain grid stability and reliability for a densely populated coastal area. The substation's operational status and voltage level underscore its role in ensuring continuous power supply to critical facilities and communities.
Environmental context
The substation is situated in a coastal plain region of Virginia, an area prone to hurricanes and sea-level rise, which can pose risks to electrical infrastructure. The facility's design likely incorporates measures to withstand extreme weather events, such as elevated equipment and flood barriers. The surrounding environment includes urban and industrial zones, with potential impacts from electromagnetic fields and stormwater runoff managed through standard mitigation practices.
