Castroville Substation is an operational electrical substation located in Texas, United States. Owned and operated by CPS Energy, the facility plays a key role in the regional power distribution network. The substation operates at a voltage of 138 kV, which is typical for sub-transmission and distribution-level infrastructure in the United States. As part of the U.S. electrical grid, Castroville Substation adheres to North American Electric Reliability Corporation (NERC) reliability standards and is subject to Federal Energy Regulatory Commission (FERC) oversight for transmission-level assets. The facility likely employs standard substation automation protocols such as IEC 61850 for communication and control. Its location in Texas places it within the Electric Reliability Council of Texas (ERCOT) interconnection, which manages the state's power grid independently. The substation supports grid stability and electricity delivery to the surrounding community. CPS Energy, based in San Antonio, is one of the largest municipally owned utilities in the U.S., serving over 800,000 electric customers. Castroville Substation contributes to the reliability and resilience of the local electrical infrastructure.
Environmental context
The substation is situated in a rural area near Castroville, Texas, characterized by agricultural land and low population density. The 138 kV voltage level indicates it serves as a distribution hub, likely connecting to lower-voltage lines for residential and commercial customers. The facility's environmental impact is minimal, with typical considerations including electromagnetic field management and stormwater runoff control. Its operation supports the integration of renewable energy sources, such as wind and solar, which are increasingly prevalent in Texas.
