San Angelo Coke Street Substation is an operational electrical substation located in San Angelo, Texas, United States. Owned and operated by American Electric Power, the facility plays a key role in the regional transmission network. With a voltage level of 138 kV, it is classified as a high-voltage substation, typical for distributing power from transmission lines to local distribution systems. 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, the facility adheres to specific grid reliability and operational protocols. The 138 kV voltage level is common for subtransmission and distribution substations in the United States, supporting industrial, commercial, and residential loads. Environmentally, the substation is situated in an urban area of San Angelo, a city in west-central Texas with a semi-arid climate. The facility's operation is critical for maintaining grid stability in the region, especially during peak demand periods. Its location within the ERCOT system underscores its importance in balancing supply and demand across the Texas interconnection. Typical substations of this voltage class require regular maintenance to ensure reliability.
Environmental context
The substation is located in San Angelo, Texas, a city with a semi-arid climate and hot summers that drive high electricity demand for cooling.
