Overview
Seco Substation is an operational electrical substation in Texas, United States, owned by South Texas Electric Cooperative. It operates at 138 kV and 12.5 kV, serving the regional grid.
Seco Substation is an electrical substation located in Texas, United States, and is owned and operated by South Texas Electric Cooperative. The facility is currently operational and plays a role in the regional power distribution network, handling voltage levels of 138 kV and 12.5 kV. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which set reliability standards for the bulk power system. As a substation in the Electric Reliability Council of Texas (ERCOT) region, it is subject to ERCOT's grid management and reliability protocols. The dual voltage levels indicate it serves both transmission (138 kV) and distribution (12.5 kV) functions. Seco Substation contributes to the electrical infrastructure of south-central Texas, supporting local communities and industries. Its location in a rural area underscores its role in extending grid reliability to less densely populated regions. The facility's operational status ensures continued service for residential, commercial, and agricultural customers in the area.
Environmental context
The substation is situated in a rural area of Texas, characterized by rolling hills and semi-arid climate. The surrounding landscape includes grasslands and scattered woodlands, which are typical of the Texas Hill Country. Electrical infrastructure in such regions must consider potential impacts on local wildlife and vegetation, particularly during construction and maintenance. The substation's design likely incorporates measures to minimize electromagnetic field exposure and prevent oil leaks from transformers, aligning with environmental best practices.
Frequently asked questions
Seco Substation is located in Texas, United States, near coordinates 29.436494, -99.238361. It is owned and operated by South Texas Electric Cooperative.
Seco Substation operates at two voltage levels: 138 kV (transmission) and 12.5 kV (distribution). This dual voltage capability allows it to step down power from high-voltage transmission lines to lower voltages for local distribution.
Seco Substation is owned by South Texas Electric Cooperative, a member-owned utility serving rural areas in south-central Texas.
As part of the U.S. bulk power system, Seco Substation must comply with NERC reliability standards and FERC regulations. Additionally, it operates within the ERCOT grid, which has its own set of operational and planning standards.
Substations like Seco are critical nodes in the electrical grid, transforming voltage levels and routing power between transmission and distribution networks. They ensure reliable electricity delivery to homes, businesses, and industries.
