Overview
Potosi Substation is an operational electrical substation in Texas, United States, owned and operated by Golden Spread Electric Cooperative. It operates at a voltage of 138 kV, serving the regional grid.
Potosi Substation is an operational electrical substation located in Texas, United States. Owned and operated by Golden Spread Electric Cooperative, the facility plays a key role in the regional transmission network. With a voltage level of 138 kV, it is classified as a high-voltage substation, typical for sub-transmission and distribution support in rural and semi-urban areas. The substation 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 part of the Electric Reliability Council of Texas (ERCOT) interconnection, the facility adheres to regional grid reliability requirements. The 138 kV voltage level is common for stepping down power from higher transmission voltages to distribution networks. Golden Spread Electric Cooperative is a generation and transmission cooperative serving member cooperatives in Texas and Oklahoma. Potosi Substation contributes to grid stability and power delivery in the region, supporting residential, commercial, and industrial loads. Its operational status ensures continued reliability for the local community and the broader ERCOT system.
Environmental context
The substation is located in a semi-arid region of Texas, characterized by grasslands and agricultural land. Electrical infrastructure in such areas must consider thermal management and vegetation clearance to prevent fire risks. The facility's design likely includes measures to minimize electromagnetic field exposure and comply with environmental regulations. Its rural setting reduces direct impact on densely populated areas, but grid reliability is critical for supporting local agriculture and energy needs.
