Guest Substation - Operational 161 kV Electrical Substation in the United States

Guest Substation is an operational electrical substation located in the United States, owned and operated by Sand Mountain Electric Cooperative. The facility operates at a voltage of 161 kV, classifying it as a transmission-level substation that plays a role in the regional power grid. As a substation in the United States, Guest Substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These bodies enforce reliability standards for transmission assets, ensuring grid stability and security. The 161 kV voltage level is typical for sub-transmission or transmission systems, connecting local distribution networks to higher-voltage bulk power systems. The substation's location in the southeastern United States places it within a region with a diverse energy mix, including natural gas, hydroelectric, and renewable sources. Its role in the grid is critical for maintaining reliable electricity supply to the surrounding communities served by Sand Mountain Electric Cooperative. The facility's operational status and voltage level underscore its importance in the local electrical infrastructure.

The substation is located in a rural area of the southeastern United States, where the electrical infrastructure supports a mix of residential, agricultural, and light industrial loads. The 161 kV voltage level suggests the substation is part of the transmission network, which can have environmental considerations such as land use for transmission corridors and potential impacts on local wildlife. However, substations themselves have a relatively small footprint and are typically designed to minimize environmental disturbance.
