Lemoyne Substation is an operational electrical substation located in Ohio, United States, owned and operated by FirstEnergy. The facility operates at voltage levels of 345 kV and 138 kV, indicating its role in both high-voltage transmission and sub-transmission within the regional power grid. As part of FirstEnergy's infrastructure, it supports the reliable delivery of electricity across the Midwest and Mid-Atlantic regions. The substation's technical specifications include dual voltage levels, which are typical for facilities that interconnect bulk power transmission lines with local distribution networks. In the United States, such substations are subject to NERC reliability standards and FERC regulation, ensuring grid stability and compliance with mandatory reliability requirements. The 345 kV level is commonly used for long-distance power transfer, while 138 kV serves regional distribution. Operationally, Lemoyne Substation plays a critical role in maintaining grid stability for the surrounding area, including industrial, commercial, and residential customers. Its location in Ohio places it within the PJM Interconnection, one of the largest regional transmission organizations in the world. The substation's continued operation supports the integration of diverse generation sources and helps meet the electricity demands of the region.
Environmental context
The substation is situated in a region with a mix of urban and agricultural land use, typical of northwestern Ohio. Its operation involves electromagnetic fields and potential impacts on local wildlife, though modern substations are designed to minimize ecological disruption. The facility's high voltage levels require careful management of insulation and safety systems to prevent environmental incidents such as oil leaks from transformers.
