Overview
FM 237 Yorktown Substation is an operational electrical substation in Texas, United States, owned and operated by Guadalupe Valley Electric Cooperative. It operates at a voltage of 138 kV, serving the local grid.
FM 237 Yorktown Substation is an operational electrical substation located in Texas, United States. The facility is owned and operated by Guadalupe Valley Electric Cooperative, a member-owned utility serving rural and suburban areas. With a voltage level of 138 kV, this substation is classified as a high-voltage transmission substation, playing a key role in stepping down power for distribution to local communities. 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, it adheres to regional grid management protocols. The 138 kV voltage level is typical for subtransmission systems, connecting larger transmission lines to distribution networks. This substation supports the electrical infrastructure of Guadalupe Valley Electric Cooperative's service territory, which includes parts of south-central Texas. Its location near Yorktown ensures reliable power delivery to agricultural and residential customers. The facility contributes to grid stability in a region prone to extreme weather events, highlighting the importance of robust substation design and maintenance.
Environmental context
The substation is situated in a rural area of Texas, characterized by agricultural land and scattered communities. The local environment is subject to hot summers and occasional severe storms, including hurricanes and tornadoes, which can pose risks to overhead electrical infrastructure. The 138 kV voltage level indicates a moderate scale of environmental footprint, with typical considerations for electromagnetic fields and land use. Vegetation management around the substation is necessary to prevent outages, and the facility's design likely includes measures to withstand extreme weather events common to the region.
