Hollymeade Substation - Virginia Electrical Substation | US Grid Infrastructure

Hollymeade Substation is an operational electrical substation located in Virginia, United States. Owned by Virginia Electric and Power Company, a subsidiary of Dominion Energy, the facility plays a key role in the regional transmission and distribution network. The substation's voltage levels of 230 kV and 34.5 kV indicate its function as a step-down substation, connecting high-voltage transmission lines to lower-voltage distribution networks. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), ensuring grid reliability and compliance with mandatory standards. As part of the PJM Interconnection, the facility adheres to stringent operational protocols. The 230 kV voltage class is typical for bulk power transmission, while the 34.5 kV level serves local distribution, reflecting the substation's role in both long-distance power transfer and local supply. Environmental considerations for this substation include its location in a region with varied topography and climate. The facility's design and operation incorporate standard practices for minimizing environmental impact, such as oil containment for transformers and noise mitigation. As part of the broader Virginia grid, Hollymeade Substation supports the state's growing energy demand and integration of renewable energy sources, contributing to grid stability and reliability.

The substation is situated in Virginia, a state with diverse ecosystems ranging from coastal plains to mountains. The facility's operation involves standard environmental management practices, including stormwater runoff control and hazardous material handling. Its location in a region with moderate seismic activity and occasional severe weather necessitates robust design for grid resilience. The substation's role in the local grid supports the area's economic activities and residential needs, with environmental impacts managed through compliance with state and federal regulations.
