Overview
Saint Marys Substation is an operational electrical substation in the United States, owned and operated by Midwest Electric Inc. It operates at a voltage of 138 kV, serving the regional grid.
Saint Marys Substation is an operational electrical substation located in the United States, owned and operated by Midwest Electric Inc. The facility is part of the nation's extensive electrical infrastructure, stepping down transmission-level voltages for local distribution. With a voltage of 138 kV, it falls within the typical range for sub-transmission substations, supporting grid stability and power delivery to surrounding communities. 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 bulk power systems. As a 138 kV facility, it is subject to NERC's Critical Infrastructure Protection (CIP) standards, ensuring cybersecurity and physical security measures are in place. Environmentally, the substation's location in Ohio places it within a region with a mix of urban and rural areas, where electrical infrastructure plays a key role in supporting industrial, commercial, and residential loads. The facility's operation contributes to the reliability of the local grid, minimizing outages and supporting economic activity. Its voltage level indicates it serves as a critical node in the regional transmission network.
Environmental context
The substation is situated in a region with a temperate climate, where seasonal weather variations can impact grid operations. Its rural-urban interface location means it supports both agricultural and residential power needs. The 138 kV voltage level suggests it is a key distribution point, with potential environmental considerations related to electromagnetic fields and land use, though standard mitigation measures are typically employed.
