Rex Brown 115kV Substation - Mississippi Electrical Substation Operated by Entergy Mississippi

Rex Brown 115kV 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 transmission network, stepping down high-voltage electricity for local distribution. The 115 kV voltage level is typical for sub-transmission systems that connect bulk power sources to distribution networks. 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 U.S. grid. As part of Entergy Mississippi's infrastructure, it supports the company's service area, which includes urban and rural communities. The facility's design likely incorporates standard substation automation protocols such as IEC 61850 for efficient monitoring and control. Environmentally, the substation's location in Mississippi places it within a region prone to severe weather, including hurricanes and thunderstorms, which can impact grid stability. The facility's role in maintaining reliable power supply is critical for local communities, supporting residential, commercial, and industrial customers. Its operational status ensures continued contribution to the regional electrical infrastructure.

The Rex Brown 115kV Substation is situated in Mississippi, a state with a humid subtropical climate and vulnerability to extreme weather events like hurricanes and tornadoes. Such conditions pose risks to electrical infrastructure, requiring robust design and maintenance. The substation's urban or rural setting influences its environmental impact, with potential considerations for land use and electromagnetic fields. Its operation aligns with grid reliability standards to mitigate weather-related disruptions.
