Overview
Pennimann Substation is an operational electrical substation in Virginia, United States, operated by Dominion Energy. It operates at a voltage of 230 kV, indicating a high-voltage transmission-level facility.
Pennimann Substation is a high-voltage electrical substation located in Virginia, United States. Operated by Dominion Energy, the facility is part of the regional transmission grid, handling a voltage of 230 kV, which classifies it as a transmission-level asset critical for bulk power transfer. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), ensuring compliance with reliability standards for grid stability. As a 230 kV facility, it plays a key role in connecting generation sources to distribution networks, typical of substations in the mid-Atlantic region. Environmental considerations for this substation include its location in a coastal area of Virginia, which may be subject to weather-related risks such as hurricanes. The facility's role in maintaining grid reliability supports local communities and industries, contributing to the overall resilience of the electrical infrastructure in the region.
Environmental context
The substation is situated in a coastal region of Virginia, an area prone to hurricanes and severe storms that can impact electrical infrastructure. Its 230 kV voltage level indicates a critical role in the transmission grid, requiring robust design to withstand extreme weather events. The facility's location near the Chesapeake Bay watershed also necessitates careful management of potential environmental impacts, such as stormwater runoff and vegetation management.
