Coral Substation - 138 kV Electrical Substation in the United States

Coral Substation is an operational electrical substation located in the United States, with coordinates 31.037544, -103.722656. The facility operates at a voltage of 138 kV, classifying it as a high-voltage substation that supports transmission and distribution networks. Substations of this voltage level are critical for stepping down power from transmission lines to sub-transmission or distribution levels, serving industrial, commercial, and residential loads. In the United States, substations like Coral are subject to regulatory oversight by the Federal Energy Regulatory Commission (FERC) and must comply with North American Electric Reliability Corporation (NERC) reliability standards. These standards ensure grid stability, cybersecurity, and operational resilience. The 138 kV voltage level is common for sub-transmission systems, often linking bulk power transmission to local distribution networks. The environmental context of Coral Substation includes its location in a rural area of Texas, where it supports the electrical infrastructure for surrounding communities and industries. Substations in such settings are essential for maintaining reliable power supply, especially in regions prone to extreme weather events. The facility's operational status indicates it is actively contributing to the regional grid, with potential implications for local energy security and economic activity.

Located in a rural area of Texas, Coral Substation operates in a region with a semi-arid climate and sparse vegetation. The substation's 138 kV voltage level indicates it serves as a critical node in the local transmission network, supporting agricultural, oil and gas, and residential loads. Its rural setting reduces immediate environmental impacts but requires robust design to withstand weather extremes such as heatwaves and occasional storms.
