Beaver Substation - High-Voltage Electrical Substation in Ohio, United States

Beaver Substation is an operational electrical substation located in Ohio, United States, owned and operated by American Transmission Systems. The facility handles high-voltage transmission at 345 kV and 138 kV, indicating its role in both bulk power transfer and sub-transmission distribution within the regional grid. 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. The dual voltage levels suggest the presence of step-down transformers, a common configuration for substations that interconnect high-voltage transmission lines with lower-voltage distribution networks. As part of the American Transmission Systems network, Beaver Substation contributes to grid stability and power delivery in the Great Lakes region. Its location in Ohio places it within the PJM Interconnection, one of the largest regional transmission organizations in the United States, which coordinates the movement of wholesale electricity across multiple states.

The substation is situated in a region with a mix of urban and rural areas, where electrical infrastructure must balance reliability with environmental considerations. The high voltage levels (345 kV) indicate potential electromagnetic field (EMF) considerations, though standard setback regulations apply. The facility's operational status suggests ongoing maintenance to minimize risks such as oil leaks from transformers, which are managed under environmental protection guidelines.
