Fredericksburg Road Substation - 138 kV Electrical Substation in San Antonio, Texas

Fredericksburg Road Substation is an operational electrical substation located in San Antonio, Texas, United States. Owned and operated by CPS Energy, the facility plays a key role in the regional power distribution network. As a 138 kV substation, it falls within the typical voltage range for sub-transmission and distribution substations in the United States. 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. CPS Energy, as a municipally owned utility, adheres to these standards to ensure grid stability and safety. The facility's voltage level of 138 kV is common for urban substations, supporting load centers in the San Antonio area. Environmentally, the substation is situated in an urban setting, which influences its design and operational practices to minimize local impacts. As part of CPS Energy's infrastructure, it contributes to the reliable electricity supply for residential, commercial, and industrial customers in the region. The substation's role in voltage regulation and power distribution is critical for maintaining grid stability and supporting community energy needs.

Located in an urban area of San Antonio, the Fredericksburg Road Substation operates within a developed environment where land use is predominantly commercial and residential. The substation's 138 kV voltage level indicates it is a key node in the local distribution network, with potential electromagnetic field considerations managed through standard siting and shielding practices. Urban substations typically have reduced ecological footprint compared to rural installations, but require careful integration with surrounding infrastructure to minimize visual and noise impacts.
