Corrigan Bulk Substation - Entergy 138 kV Substation in Texas

Corrigan Bulk Substation is a high-voltage electrical substation located in Texas, United States, owned and operated by Entergy. Operating at 138 kV, it is a medium-scale transmission asset that steps down voltage for distribution or interconnects transmission lines, supporting the regional grid. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for bulk power systems. Entergy, as the owner and operator, complies with these standards to ensure stable and secure electricity delivery. The 138 kV voltage level is typical for sub-transmission and distribution substations in the US, serving industrial, commercial, and residential loads. Located in a rural area of Texas, Corrigan Bulk Substation contributes to the reliability of the local power supply, supporting communities and industries in the region. Its operational status and adherence to NERC standards help maintain grid resilience against weather and demand fluctuations, which is critical in Texas's diverse climate.

The substation is situated in a rural area of Texas, where the local environment includes forests and agricultural land. Its operation involves electromagnetic fields and potential impacts on wildlife, but standard mitigation measures are typically employed. The 138 kV voltage level indicates moderate infrastructure footprint, with rights-of-way managed to minimize ecological disruption.
