Seadoc Substation: 138 kV Electrical Substation in the United States

Seadoc Substation is an operational electrical substation located in the United States, with coordinates 28.952188, -95.434648. The facility operates at a voltage level of 138 kV, which is typical for sub-transmission and distribution substations, serving to step down power from high-voltage transmission lines to lower voltages for local distribution. As a substation in the United States, Seadoc Substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) reliability standards and the Federal Energy Regulatory Commission (FERC) for transmission-level assets. The facility likely adheres to standards for grid stability, protection, and automation, including the use of ISO/IEC 61850 for substation automation and communication. The substation's location near the Gulf Coast of Texas places it in a region with significant industrial activity, including petrochemical and refining operations, which demand reliable electricity supply. Its operational status ensures continued support for local grid stability and power delivery to residential, commercial, and industrial customers in the area.

The substation is located in a coastal region of Texas, an area prone to hurricanes and severe weather events that can impact electrical infrastructure. The facility's design likely incorporates resilience measures such as elevated equipment and flood protection to mitigate storm-related risks. Its operation supports the local grid, which serves a mix of urban, rural, and industrial loads, including petrochemical facilities along the Gulf Coast.
