Westwego Substation - 115 kV Electrical Substation in Westwego, Louisiana

Westwego Substation is an operational electrical substation located in Westwego, Louisiana, United States. It operates at a voltage of 115 kV, placing it in the medium-voltage range typical for distribution and sub-transmission networks. The substation plays a key role in the local power grid, stepping down higher transmission voltages for distribution to residential and commercial customers in the Westwego area. As part of the United States electrical infrastructure, this substation operates under the regulatory framework established by the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These bodies enforce reliability standards and ensure the stability of the bulk power system. The 115 kV voltage level is common for sub-transmission systems that connect major transmission lines to local distribution networks. The substation's location in Westwego, a suburb of New Orleans, places it within a region vulnerable to hurricanes and flooding. Its operational status is critical for maintaining grid stability in this area, supporting emergency response and recovery efforts during extreme weather events. The facility contributes to the resilience of the local electrical infrastructure by providing a reliable point of power distribution.

The Westwego Substation is situated in a low-lying coastal region of Louisiana, which is prone to hurricanes, storm surges, and flooding. The substation's design and operation must account for these environmental risks to ensure grid reliability. Its voltage level of 115 kV indicates a role in sub-transmission, which is critical for distributing power from larger transmission lines to local distribution networks. The facility's location in an urban-suburban area means it serves a dense population center, requiring robust infrastructure to withstand extreme weather events.
