Overview
Stonewater Switching Station is a 230 kV substation in Virginia, United States, operated by Virginia Electric and Power Company. It plays a key role in regional grid stability.
Stonewater Switching Station is an electrical substation located in Virginia, United States, operated by Virginia Electric and Power Company. The facility operates at a voltage of 230 kV, classifying it as a high-voltage transmission-level asset critical for bulk power transfer and grid reliability. The substation falls under the regulatory oversight of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for the interconnected power system. As part of the PJM Interconnection regional transmission organization, it must comply with mandatory reliability standards and grid operational protocols. This facility serves as a switching station, enabling the routing and control of electrical power within the transmission network. Its location in Virginia supports the growing energy demands of the region, contributing to the stability and resilience of the local electrical infrastructure.
Environmental context
The substation is situated in a region with a mix of urban and suburban development, typical of Northern Virginia. The local electrical infrastructure must accommodate increasing population density and commercial activity. The 230 kV voltage level indicates its role in long-distance power transmission, which can have land-use implications for transmission corridors. Proper maintenance of switchgear and insulation is essential to minimize environmental risks such as oil leaks or SF6 emissions.
