Overview
Lynnhaven Substation is an operational electrical substation in Virginia, United States, owned and operated by Virginia Electric and Power Company. It operates at 230 kV, serving the regional grid.
Lynnhaven 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. With a voltage level of 230 kV, it is classified as a high-voltage substation, typical of infrastructure supporting bulk power transfer and distribution to urban and suburban areas. 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 the U.S. grid. As part of the PJM Interconnection, the facility adheres to mandatory reliability standards, including NERC CIP for cybersecurity and FERC Order 1000 for transmission planning. The 230 kV voltage level indicates its role in stepping down power from higher transmission voltages for local distribution. Lynnhaven Substation contributes to grid stability and reliability in the Hampton Roads region. Its coastal location near Virginia Beach underscores its importance in serving a densely populated area with critical infrastructure, including military installations and tourism hubs. The facility's operational status ensures continued support for regional electricity demand and resilience against weather-related disruptions.
Environmental context
The substation is situated in a coastal urban environment, where grid reliability is critical for hurricane-prone areas. Its 230 kV voltage level places it in the high-voltage transmission category, requiring robust design to withstand extreme weather. The surrounding region's mix of residential, commercial, and military loads demands consistent power quality, with the substation serving as a key node in the local distribution network.
