Overview
Southwest Lima Substation is an operational electrical substation in Ohio, United States, owned and operated by American Electric Power. It handles voltages of 345 kV and 138 kV, serving as a key node in the regional transmission grid.
Southwest Lima Substation is an operational electrical substation located in Ohio, United States. Owned and operated by American Electric Power (AEP), the facility is a critical component of the regional high-voltage transmission network, handling voltages of 345 kV and 138 kV. This places it in the large-scale category for substations, supporting bulk power transfer and grid stability. 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 transmission-level assets. As part of AEP's system, it likely incorporates modern automation and protection schemes compliant with industry standards such as IEEE C37. Substations of this voltage class are typically equipped with circuit breakers, transformers, and switchgear designed for high-capacity operations. Environmentally, the substation's location in Ohio places it within a region with a mix of urban and rural areas. Its role in the grid is significant for local communities and industries, ensuring reliable power delivery. The facility's operational status contributes to the resilience of the regional electrical infrastructure, supporting economic activities and daily life in the surrounding area.
Environmental context
The substation is situated in Ohio, a state with diverse geography including agricultural lands and urban centers. Its operation involves electromagnetic fields and potential impacts on local wildlife, though modern substations are designed with mitigation measures. The facility's high voltage levels indicate a critical role in grid stability, which is essential for integrating renewable energy sources and managing load fluctuations.
