Overview
Liston Substation is an operational electrical substation in the United States, owned and operated by American Electric Power. It operates at a voltage of 138 kV, supporting regional grid stability.
Liston Substation is an operational electrical substation located in the United States, owned and operated by American Electric Power. The facility operates at a voltage of 138 kV, placing it in the medium-to-high voltage range typical for sub-transmission and distribution substations that serve industrial and residential loads. As part of the American Electric Power system, Liston Substation adheres to North American Electric Reliability Corporation (NERC) reliability standards and is subject to Federal Energy Regulatory Commission (FERC) regulation for transmission-level assets. The substation likely employs modern protection and control systems, including those based on the IEC 61850 standard for substation automation, ensuring efficient and reliable power distribution. The substation plays a critical role in the local electrical infrastructure, supporting grid stability and power delivery to the surrounding area. Its location in southern Texas places it in a region with growing energy demand, and its operational status ensures continued service to the community. The facility's 138 kV voltage level is common for interconnecting with higher-voltage transmission lines and distributing power to lower-voltage networks.
Environmental context
The substation is located in a region with a subtropical climate, which can pose challenges such as heat and humidity that affect equipment performance and longevity. The area is also prone to extreme weather events like hurricanes, requiring robust design and maintenance practices to ensure grid resilience. The substation's urban or rural setting influences its environmental impact, with potential considerations for electromagnetic fields and land use.
