Overview
Security Substation, operated by Sam Houston Electric Cooperative, is an operational 138 kV substation located in Texas, United States, serving as a key node in the regional electrical grid.
Security Substation is an operational electrical substation located in Texas, United States, and operated by Sam Houston Electric Cooperative. The facility operates at a voltage of 138 kV, placing it within the sub-transmission to transmission voltage range typical for distributing power from bulk transmission systems to local distribution networks. As part of the Electric Reliability Council of Texas (ERCOT) grid, the substation plays a role in maintaining reliable electricity supply to the surrounding region. The substation's technical specifications indicate a voltage level of 138 kV, which is common for regional power distribution in the United States. Under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Texas Reliability Entity (TRE), the facility must comply with reliability standards for grid stability and operational safety. The operator, Sam Houston Electric Cooperative, is a member-owned utility serving several counties in Southeast Texas, ensuring local oversight and community-focused service. Environmental and operational significance of Security Substation lies in its contribution to grid resilience and rural electrification. As part of the ERCOT system, the substation supports the integration of diverse generation sources, including natural gas, wind, and solar, which are prevalent in Texas. Its location in a rural area underscores its role in delivering electricity to agricultural and residential customers, while also facilitating potential future grid modernization efforts such as smart grid technologies and distributed energy resource integration.
Environmental context
Located in a rural area of Texas, Security Substation operates within the ERCOT grid, which faces environmental challenges including extreme weather events like hurricanes and winter storms. The substation's 138 kV infrastructure is designed to withstand local climate conditions, and its role in distributing power from transmission lines to local networks helps minimize transmission losses. The surrounding region's mix of forest and agricultural land requires careful siting to avoid habitat disruption, though the substation's footprint is relatively small.
