Carville Substation is an operational electrical substation located in Maryland, United States. Owned and operated by Delmarva Power, it plays a key role in the regional transmission and distribution network. The substation handles voltages of 138 kV and 25 kV, indicating its function in stepping down high-voltage transmission power for local distribution. As part of the U.S. electrical infrastructure, Carville Substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These bodies enforce reliability standards and oversee interstate electricity transmission. The substation's voltage levels suggest it is a medium-scale facility typical of substations serving suburban or rural areas. The substation's location in Maryland places it within the PJM Interconnection, one of the largest regional transmission organizations in the U.S. This ensures grid stability and reliability for the surrounding communities. Delmarva Power, a subsidiary of Exelon, serves over 500,000 customers in Delaware, Maryland, and Virginia, making Carville Substation an integral part of the regional power supply.
Environmental context
Carville Substation is situated in a rural area of Maryland, near agricultural land and small communities. The substation's operation involves electromagnetic fields and potential impacts on local wildlife, though standard mitigation measures are typically employed. Its location away from dense urban centers reduces exposure to sensitive populations, but proximity to farmland requires careful management of any potential environmental risks.
