Vancleave Substation - 115 kV Electrical Substation in Mississippi

Vancleave Substation is an operational electrical substation located in Vancleave, Mississippi, United States. It is owned and operated by Singing River Electric Cooperative, a member-owned utility serving parts of Mississippi and Alabama. The substation operates at a voltage of 115 kV, which is typical for sub-transmission and distribution-level infrastructure in rural cooperative networks. The facility 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. As a 115 kV substation, it plays a role in stepping down power from higher transmission voltages for local distribution. Singing River Electric Cooperative's system includes multiple substations and over 2,000 miles of line, serving approximately 80,000 members. This substation is part of the cooperative's infrastructure supporting residential, commercial, and agricultural customers in the Gulf Coast region. Its location in a rural area means it is critical for maintaining reliable power supply to communities that may have limited redundancy. It contributes to the overall stability of the local grid.

The substation is located in a rural area of southern Mississippi, near the Gulf Coast. The region is prone to hurricanes and severe weather, which can pose risks to electrical infrastructure. The 115 kV voltage level indicates it is part of the sub-transmission network, which is essential for distributing power to local communities. The surrounding environment includes forests and wetlands, and the substation's design likely includes measures to withstand storm events.
