Overview
Cauthorn Substation is an operational electrical substation in Texas, United States, operated by Southwest Texas Electric Cooperative. It handles voltages of 138 kV and 24.9 kV, serving the local grid.
Cauthorn Substation is an operational electrical substation located in Texas, United States, owned and operated by Southwest Texas Electric Cooperative. The facility handles transmission-level voltage of 138 kV and distribution-level voltage of 24.9 kV, indicating its role in stepping down power for local distribution. As a substation in the United States, Cauthorn Substation operates under the regulatory framework established by the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These standards ensure grid reliability and security for transmission assets. The substation likely employs standard automation and protection systems, such as those based on IEC 61850, to manage power flow and maintain stability. The substation serves the rural region of southwest Texas, contributing to the electrical infrastructure that supports agricultural, residential, and commercial activities. Its location in a sparsely populated area underscores its importance in extending reliable power to remote communities. The cooperative ownership model reflects a community-focused approach to electricity distribution.
Environmental context
The substation is situated in a semi-arid region of Texas, characterized by low rainfall and high temperatures. The surrounding landscape consists of grasslands and scrub, with minimal industrial activity. The facility's environmental impact is primarily related to land use and potential electromagnetic fields, which are managed through standard siting practices. The substation's role in the grid helps integrate renewable energy sources, such as wind and solar, which are increasingly prevalent in Texas.
