Overview
LNG Substation is an operational electrical substation in the United States, operated by Entergy. It handles voltages of 138 kV and 4.16 kV, serving as a key node in the regional grid.
LNG Substation is an operational electrical substation located in the United States, specifically at coordinates 30.444083, -95.522136, which places it in Texas near the Gulf Coast. The facility is owned and operated by Entergy, a major utility company serving the southern United States. With voltage levels of 138 kV and 4.16 kV, this substation is classified as a medium-to-high voltage facility, playing a critical role in stepping down transmission-level power for local distribution. As a substation operating under the jurisdiction of the United States, it adheres to NERC reliability standards and FERC regulations for grid stability. The 138 kV voltage level indicates it is part of the high-voltage transmission network, while the 4.16 kV side serves industrial or large commercial customers. Entergy's substations are typically equipped with modern switchgear and automation systems compliant with ISO/IEC 61850 standards, ensuring efficient and reliable power flow. The substation's location in a region prone to hurricanes and extreme weather underscores its importance for grid resilience. It supports the local economy by providing stable electricity to industrial facilities, including LNG terminals, and contributes to the overall reliability of the Texas Interconnection. Its operational status ensures continued service to communities and critical infrastructure in the area.
Environmental context
The substation is situated in a region with a humid subtropical climate, where high temperatures and occasional severe storms pose challenges to electrical infrastructure. Its proximity to the Gulf Coast means it must withstand hurricane-force winds and flooding, necessitating robust design and maintenance. The facility's role in supporting LNG operations also ties it to the broader energy transition, balancing natural gas exports with grid stability.
