PEPCO Substation 117 - Washington, D.C. Electrical Substation

PEPCO Substation 117 is an operational electrical substation located in Washington, D.C., United States. Owned by Potomac Electric Power Company (PEPCO), it serves as a critical node in the regional power distribution network. The substation is part of the broader infrastructure that supplies electricity to the nation's capital and surrounding areas. As a substation, this facility transforms voltage levels and routes power within the grid. While specific technical specifications such as voltage level are not detailed, substations of this type typically operate at medium to high voltages (e.g., 69 kV to 138 kV) to distribute electricity from transmission lines to local distribution networks. PEPCO, a subsidiary of Exelon Corporation, operates under the regulatory oversight of the Federal Energy Regulatory Commission (FERC) and adheres to North American Electric Reliability Corporation (NERC) reliability standards. The substation's location in downtown Washington, D.C., underscores its importance in supplying power to a dense urban area with high demand, including government buildings, commercial centers, and residential neighborhoods. Its operational status ensures grid stability and reliability for critical infrastructure in the capital region.

Located in an urban environment, PEPCO Substation 117 is situated in a densely populated area with high electricity demand. The substation's operation involves electromagnetic fields and potential noise, typical of urban substations. Its presence supports the integration of renewable energy sources and grid resilience, contributing to the local energy transition.
