Overview
Sub 4 is an operational electrical substation located in the United States, operating at 100 kV. It plays a role in regional power distribution and grid stability.
Sub 4 is an operational electrical substation located in the United States, with coordinates 35.996876, -78.937776. The facility operates at a voltage level of 100 kV, placing it within the medium-voltage range typical for distribution substations that serve local industrial, commercial, and residential loads. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and is subject to Federal Energy Regulatory Commission (FERC) oversight for reliability standards. In the United States, substations like Sub 4 are critical nodes in the bulk power system, ensuring voltage regulation and power flow control. The 100 kV voltage level suggests this facility likely connects transmission lines to lower-voltage distribution networks. As part of the U.S. electrical infrastructure, Sub 4 contributes to grid resilience and energy delivery in its region. Its operational status indicates ongoing service, supporting local communities and industries. The facility's location in the southeastern United States places it in an area with growing energy demand, where substations play a key role in integrating renewable energy sources and maintaining grid stability.
Environmental context
The substation is located in the southeastern United States, a region characterized by a humid subtropical climate with hot summers and mild winters. Electrical infrastructure in this area must withstand occasional severe weather events such as thunderstorms and hurricanes, which can impact grid reliability. The 100 kV voltage level and operational status suggest the facility is designed to meet local load demands while adhering to environmental regulations for electromagnetic fields and noise.
