OCI Alamo 1 is a substation located in Texas, United States, owned and operated by CPS Energy. As a 138 kV substation, it plays a key role in the regional transmission and distribution network, supporting the electricity needs of the San Antonio area. The facility operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), ensuring grid reliability and compliance with mandatory standards. The 138 kV voltage level classifies it as a medium-voltage substation, typical for subtransmission and distribution within urban and suburban environments. As part of CPS Energy's infrastructure, OCI Alamo 1 contributes to the stability and resilience of the local power grid. Its location in a growing metropolitan area underscores its importance in meeting increasing electricity demand and supporting community services.

Located in a semi-arid region of Texas, the substation's operation is influenced by local climate conditions, including high summer temperatures that drive peak electricity demand for cooling. The facility's urban setting requires careful management of electromagnetic fields and noise, while its role in grid stability supports the integration of renewable energy sources like solar and wind, which are expanding in the state.
