Potomac River Substation - 230 kV Electrical Substation in the United States

Potomac River Substation is an operational electrical substation located in the United States, with coordinates 38.820806, -77.042184. As a 230 kV substation, it operates at a high-voltage level typical of transmission infrastructure, facilitating the efficient transfer of electricity across the grid. The facility is part of the broader North American power system, which is regulated by NERC reliability standards and FERC oversight for interstate transmission. The substation's voltage level of 230 kV places it in the medium-to-high voltage range, commonly used for regional transmission networks. Such substations are critical for stepping down power from higher-voltage lines for distribution or interconnecting different parts of the grid. In the United States, substations like this one must comply with NERC's Critical Infrastructure Protection (CIP) standards to ensure cybersecurity and physical security. Located near the Potomac River, the substation serves the surrounding urban and suburban areas, supporting residential, commercial, and industrial electricity demand. Its operational status ensures continued reliability of the local grid, contributing to the overall stability of the regional power system. The facility's role in voltage regulation and power flow management is essential for maintaining service quality and preventing outages.

The substation's location near the Potomac River places it in a region with sensitive aquatic ecosystems. While substations themselves have minimal direct environmental impact, their operation supports the integration of renewable energy sources and grid efficiency, which can reduce overall emissions. The 230 kV voltage level indicates a significant role in the transmission network, potentially influencing land use and local wildlife corridors through associated transmission lines.
