Overview
Swain Tie Substation is an operational electrical substation in the United States, owned and operated by Duke Energy. It handles voltages of 161 kV, 66 kV, and 13 kV, serving as a key node in the regional grid.
Swain Tie Substation is an operational electrical substation located in the United States, owned and operated by Duke Energy, a major utility in the region. The facility handles multiple voltage levels including 161 kV, 66 kV, and 13 kV, indicating its role in stepping down transmission-level power to sub-transmission and distribution voltages. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for the bulk power system. As part of Duke Energy's network, it likely complies with NERC Critical Infrastructure Protection (CIP) standards and participates in regional transmission planning through entities like the Southeastern Electric Reliability Council (SERC). This substation plays a critical role in maintaining grid stability and power delivery in the surrounding area. Its location in a mountainous region of North Carolina may pose environmental considerations such as vegetation management and storm resilience. The facility contributes to the reliability of electricity supply for local communities and industries.
Environmental context
The substation is situated in a mountainous region of western North Carolina, an area characterized by forested terrain and variable weather patterns. The local environment requires careful vegetation management to prevent outages from falling trees or branches. Storm events, including ice storms and heavy rainfall, can impact overhead lines and equipment, making resilience planning important for continuous operation.
Frequently asked questions
Swain Tie Substation is located in the United States, specifically in the mountainous region of western North Carolina, near the Great Smoky Mountains.
