Main Line Substation - 69 kV Electrical Substation in the United States

Main Line Substation is an operational electrical substation located in the United States, with coordinates 30.545176, -91.167320. It is owned and operated by Products (SE) Pipe Line Corporation, a company involved in pipeline operations. The substation operates at a voltage of 69 kV, which classifies it as a medium-voltage substation typically used for sub-transmission or distribution within the electrical grid. The substation's technical specifications include a voltage level of 69 kV, which is common for regional power distribution and industrial supply. In the United States, substations of this voltage are subject to NERC reliability standards and FERC regulation, ensuring grid stability and compliance with federal guidelines. The facility likely plays a role in stepping down power from higher transmission voltages for local distribution or supporting pipeline infrastructure. As part of the U.S. electrical infrastructure, Main Line Substation contributes to the reliability of power supply in its region. Its operation by a pipeline company suggests a specialized role in supporting energy transport infrastructure. The substation's location in the southern U.S. places it within a grid that must manage seasonal weather challenges, including hurricanes, which underscores the importance of robust substation design and maintenance.

The substation is located in a region with a humid subtropical climate, characterized by hot summers and mild winters. The area is prone to thunderstorms and hurricanes, which can pose risks to electrical infrastructure. The substation's design likely incorporates measures to withstand extreme weather, such as elevated equipment and flood protection. Its operation supports local industry and communities, but the environmental context requires ongoing maintenance to ensure resilience against natural events.
