Overview
Donaldsonville Substation, operated by Entergy Louisiana in the United States, is an operational electrical substation handling voltages of 230 kV and 13.8 kV.
Donaldsonville Substation is an operational electrical substation located in the United States, specifically in the state of Louisiana. It is owned and operated by Entergy Louisiana, a major utility company serving the region. The substation handles multiple voltage levels, including 230 kV for transmission and 13.8 kV for distribution, indicating its role in both high-voltage transmission and local distribution. As part of the U.S. electrical infrastructure, this substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These standards ensure grid reliability and security. The substation likely uses modern switchgear and automation systems compliant with standards such as IEEE C37 for substation equipment. The substation plays a critical role in the local grid by stepping down transmission voltages for distribution to residential, commercial, and industrial customers in the Donaldsonville area. Its location in Louisiana, a state prone to hurricanes, requires robust design and emergency response protocols to maintain grid stability during extreme weather events.
Environmental context
The substation is situated in a region with a humid subtropical climate, which can lead to challenges such as corrosion and vegetation management. Its proximity to the Mississippi River and industrial facilities in the area may require careful environmental planning to mitigate risks of flooding and chemical exposure. The substation's design likely incorporates measures to withstand severe weather, including elevated equipment and flood barriers.
