Overview
Quanex Substation is an operational electrical substation in Texas, United States, owned and operated by San Bernard Electric Cooperative. It operates at voltage levels of 69 kV and 12.5 kV.
Quanex Substation is an operational electrical substation located in Texas, United States, owned and operated by San Bernard Electric Cooperative. The facility serves as a key node in the local electrical distribution network, stepping down transmission-level voltage for distribution to residential, commercial, and industrial customers in the region. The substation operates at voltage levels of 69 kV and 12.5 kV, typical for a distribution substation that connects the subtransmission system to local distribution feeders. As part of the U.S. electrical grid, the facility adheres to North American Electric Reliability Corporation (NERC) reliability standards and is subject to Federal Energy Regulatory Commission (FERC) oversight for transmission-level assets. The substation likely employs modern switchgear and protection systems to ensure grid stability and safety. Located in a rural area of Texas, Quanex Substation supports the electrical infrastructure of the surrounding community, providing reliable power to agricultural, residential, and small commercial loads. Its role in the distribution network is critical for maintaining voltage stability and service continuity in the region. The facility's operational status and integration with the broader grid underscore its importance to local energy security.
Environmental context
The substation is situated in a rural area of Texas, where the local environment includes agricultural land and scattered residential developments. Electrical infrastructure in such settings must consider potential impacts on wildlife and vegetation, particularly during construction and maintenance. The facility's voltage levels and equipment are designed to minimize electromagnetic field exposure and comply with environmental regulations. The rural location also reduces the risk of urban-related hazards such as vandalism or accidental contact.
