South Beaumont Substation | Entergy Electrical Substation in Beaumont, Texas

South Beaumont Substation is an operational electrical substation located in Beaumont, Texas, United States. Owned and operated by Entergy, the facility plays a key role in the regional transmission and distribution network, handling voltage levels of 138 kV and 69 kV. As part of the Entergy system, it supports electricity delivery to residential, commercial, and industrial customers in Southeast Texas. 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. The facility's dual voltage levels indicate it serves both transmission (138 kV) and sub-transmission (69 kV) functions, typical for substations that step down power for local distribution. Entergy, a major utility in the Gulf Coast region, maintains a portfolio of substations to ensure grid stability and resilience. Environmentally, the substation is situated in a region prone to hurricanes and severe weather, making grid hardening and reliability critical. The facility's role in the Entergy network contributes to the energy supply for the Beaumont area, which includes industrial facilities along the Gulf Coast. Its operational status ensures continued support for local communities and economic activities.

The substation is located in Beaumont, Texas, a coastal area susceptible to hurricanes and flooding, which poses risks to electrical infrastructure. The facility's voltage levels (138 kV and 69 kV) indicate its role in both transmission and distribution, requiring robust design to withstand extreme weather. Entergy's grid in this region is subject to NERC reliability standards that mandate vegetation management and equipment protection to minimize outage risks.
