Overview
West McComb Substation is an operational electrical substation in Mississippi, United States, owned and operated by Entergy Mississippi. It operates at 115 kV, serving the local grid.
West McComb Substation is an operational electrical substation located in Mississippi, United States. Owned and operated by Entergy Mississippi, the facility plays a key role in the regional power distribution network. The substation operates at a voltage of 115 kV, which is typical for sub-transmission and distribution-level infrastructure in the United States. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which set reliability standards for the bulk power system. As part of Entergy Mississippi's network, it contributes to the stability and reliability of the local grid. The 115 kV voltage level indicates it serves as a critical link between higher-voltage transmission lines and lower-voltage distribution networks. Environmental and operational significance of West McComb Substation lies in its role in delivering electricity to the surrounding community. Substations like this are essential for voltage regulation and load management, supporting residential, commercial, and industrial customers. Its location in Mississippi, a state prone to severe weather, underscores the importance of robust infrastructure for grid resilience.
Environmental context
The substation is located in a region of Mississippi with a humid subtropical climate, characterized by hot summers and mild winters. The area is susceptible to thunderstorms, hurricanes, and tornadoes, which can pose risks to electrical infrastructure. The 115 kV voltage level and the substation's role in the local distribution network make it a critical asset for maintaining grid stability during extreme weather events. Its urban or rural setting influences the surrounding land use and potential environmental impacts, such as electromagnetic fields or land disturbance.
