Overview
Virgil C. Summer Nuclear #1 Substation is an operational 230 kV substation in South Carolina, United States. It supports the nuclear power plant's grid connection and regional transmission stability.
Virgil C. Summer Nuclear #1 Substation is a key electrical infrastructure facility located near Jenkinsville, South Carolina, United States. Operating at 230 kV, it serves as the primary substation for the Virgil C. Summer Nuclear Generating Station, facilitating the transmission of generated power into the regional grid. The substation is operational and plays a critical role in the area's energy supply. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), ensuring compliance with reliability standards for bulk power systems. At 230 kV, it is classified as a high-voltage substation, typical for connecting large generation sources to the transmission network. The facility utilizes modern switchgear and automation systems consistent with ISO/IEC 61850 standards for substation communication. Environmentally, the substation is situated in a rural area near the Broad River, with the surrounding region characterized by mixed forest and agricultural land. Its operation supports the integration of nuclear power, a low-carbon energy source, into the grid. The substation's reliability is essential for maintaining grid stability in the region and for the safe transmission of electricity from the nuclear plant to consumers.
Environmental context
The substation is located in a rural area of South Carolina, near the Broad River, with the surrounding landscape consisting of forests and farmland. The facility's 230 kV voltage level indicates its role in high-voltage transmission, which is critical for grid stability.
