Overview
Jefferson Street Substation is an operational 230 kV substation owned by Dominion Energy in the United States. It plays a key role in regional grid stability and power distribution.
Jefferson Street Substation is a 230 kV electrical substation located in the United States, owned and operated by Dominion Energy. As a high-voltage substation, it serves as a critical node in the transmission network, stepping down voltage for distribution to residential, commercial, and industrial customers. The facility is currently operational and contributes to the reliability of the regional power grid. The substation operates at 230 kV, a common voltage level for bulk power transmission in the United States. It falls under the regulatory oversight of the Federal Energy Regulatory Commission (FERC) and must comply with North American Electric Reliability Corporation (NERC) reliability standards. Dominion Energy, as the owner and operator, adheres to these standards to ensure grid stability and prevent cascading failures. The facility likely employs modern switchgear and protection systems, including those based on IEC 61850 for substation automation. Located in an urban area, Jefferson Street Substation supports the electrical infrastructure of the surrounding community by providing reliable power supply. Its strategic position within Dominion Energy's network enhances grid resilience and facilitates the integration of distributed energy resources. The substation's operational status and voltage level underscore its importance in maintaining continuous electricity service to end-users.
Environmental context
The substation's urban location means it operates in a densely populated area, where electromagnetic fields and noise are managed to minimize community impact. Its 230 kV voltage level indicates a significant role in the transmission grid, with potential environmental considerations related to land use and visual impact. Typical substations of this scale are designed with containment measures for insulating fluids to prevent soil and water contamination.
