Myrtle Substation - Virginia Electrical Substation Operated by Dominion Energy

Myrtle 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 and distribution network. The substation handles voltages of 115 kV and 34.5 kV, indicating its function in stepping down power from high-voltage transmission lines to lower-voltage distribution circuits. 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 bulk power system. As part of the Virginia electric grid, Myrtle Substation is subject to state-level oversight by the Virginia State Corporation Commission. The facility's voltage levels are typical for a medium-to-large substation supporting both industrial and residential loads in the region. Myrtle Substation contributes to grid stability and reliability in southeastern Virginia, an area with a mix of urban, suburban, and rural communities. Its location near the Great Dismal Swamp and the Hampton Roads metropolitan area underscores its importance in serving a diverse customer base. The substation's operational status and integration with the broader PJM Interconnection grid ensure continued electricity supply to the region.

The substation is situated in a region characterized by a mix of forested wetlands and agricultural land, with the nearby Great Dismal Swamp providing important ecological functions such as flood control and carbon sequestration. The facility's operation involves electromagnetic fields and potential impacts on local wildlife, though modern substation design typically includes measures to minimize environmental disturbance. The surrounding area's climate, with hot summers and mild winters, influences the substation's cooling and maintenance requirements.
