Overview
Frio Town Substation is an operational electrical substation in Texas, United States, operated by South Texas Electric Cooperative with a voltage of 69 kV.
Frio Town Substation is an operational electrical substation located in Texas, United States. It is owned and operated by South Texas Electric Cooperative, a member-owned utility serving rural areas in south-central Texas. The substation operates at 69 kV, a typical voltage level for sub-transmission and distribution networks in the region. The substation falls under the jurisdiction of the North American Electric Reliability Corporation (NERC) and the Electric Reliability Council of Texas (ERCOT), which enforce reliability standards for the bulk power system. As a 69 kV facility, it plays a role in stepping down power from higher voltage transmission lines to distribution levels for local communities. South Texas Electric Cooperative is a generation and transmission cooperative that supplies power to distribution cooperatives in the area. Frio Town Substation supports the electrical infrastructure of rural Frio County and surrounding areas, contributing to grid stability and reliability for agricultural and residential customers. Its location in south-central Texas places it within a region that experiences high summer demand due to air conditioning loads, making substation reliability critical for peak demand periods.
Environmental context
The substation is located in a rural area of south-central Texas, characterized by hot summers and mild winters. The surrounding landscape is primarily agricultural, with ranching and crop farming. The 69 kV voltage level indicates it serves local distribution needs, and its operation is subject to ERCOT's grid management, which includes environmental compliance for land use and electromagnetic fields. Typical substations in this region are maintained to withstand extreme weather events like thunderstorms and occasional hurricanes.
