Overview
La Sara Substation is an operational electrical substation in Texas, United States, owned and operated by South Texas Electric Cooperative. It operates at a voltage of 138 kV, serving the regional grid.
La Sara Substation is an operational electrical substation located in Texas, United States. Owned and operated by South Texas Electric Cooperative, it plays a key role in the regional transmission network. The substation operates at a voltage of 138 kV, which is typical for sub-transmission and distribution-level infrastructure in rural and suburban areas. 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 substation owned by a cooperative, it is part of a decentralized utility model common in rural Texas, where cooperatives ensure reliable power delivery to less densely populated regions. The substation's location in southern Texas places it in a region with growing energy demand due to industrial and agricultural activities. Its role in stepping down voltage for local distribution supports community reliability and grid stability. The facility's operational status and voltage level indicate it is a medium-scale asset critical to the local electrical infrastructure.
Environmental context
The substation is located in a rural area of southern Texas, characterized by flat terrain and agricultural land. The region experiences a subtropical climate with hot summers and mild winters, which can affect equipment performance and maintenance schedules. The facility's voltage level and rural setting suggest it is designed to withstand local weather conditions, including occasional hurricanes and severe storms, which are common in the Gulf Coast region.
