Overview
Normanna Substation is an operational electrical substation in Texas, United States, owned and operated by American Electric Power. It operates at a voltage of 69 kV, serving as a key node in the regional transmission grid.
Normanna Substation is an operational electrical substation located in Texas, United States. Owned and operated by American Electric Power, one of the largest electric utilities in the country, this facility plays a role in the regional power transmission network. With a voltage level of 69 kV, it is classified as a sub-transmission or distribution substation, typically serving local industrial, commercial, and residential loads. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for the bulk power system. As part of the Electric Reliability Council of Texas (ERCOT) interconnection, Normanna Substation adheres to specific grid reliability and operational protocols. The 69 kV voltage level is common for distribution substations that step down power from higher transmission voltages for local distribution. Located in a rural area of Texas, the substation supports the electrical infrastructure for agricultural and small community needs. Its operational status ensures stable power supply to the surrounding region, contributing to grid resilience. The facility's age and specific equipment details are not publicly available, but its role within the American Electric Power network underscores its importance in maintaining reliable electricity service.
Environmental context
The substation is situated in a rural area of Texas, where the local environment is characterized by agricultural land and scattered communities. Electrical infrastructure like Normanna Substation is designed to minimize visual and ecological impact, with standard practices including vegetation management and wildlife protection measures. The 69 kV voltage level indicates a moderate scale, with typical environmental considerations focused on electromagnetic field management and stormwater runoff control.
