Poteet Substation - Electrical Substation in Texas, United States

Poteet Substation is an electrical substation located in Texas, United States, and is owned and operated by South Texas Electric Cooperative. The facility is operational and serves as a key node in the regional power grid, stepping down transmission-level voltage for local distribution. The substation operates at voltage levels of 69,000 volts (69 kV) and 12,500 volts (12.5 kV), which are typical for sub-transmission and distribution applications in the United States. As part of the South Texas Electric Cooperative's network, it likely adheres to NERC reliability standards and FERC regulations for grid stability and safety. Located in rural Texas, Poteet Substation plays a critical role in delivering electricity to the surrounding community. Its operation supports the cooperative's mission to provide reliable power to member-owners, contributing to the region's agricultural and residential energy needs.

The substation is situated in a rural area of Texas, where the local environment is characterized by semi-arid conditions and agricultural land use. Electrical infrastructure in such settings must be designed to withstand extreme weather events, including heatwaves and occasional flooding. The facility's voltage levels and equipment age are factors in its environmental impact, with modern switchgear typically incorporating SF6-free alternatives to reduce greenhouse gas emissions.
