Overview
South Berwick Substation is an operational electrical substation in Ohio, United States, owned and operated by AEP Ohio. It handles voltages of 345 kV and 69 kV, serving the regional grid.
South Berwick Substation is an operational electrical substation located in Ohio, United States. Owned and operated by AEP Ohio, the facility plays a key role in the regional transmission and distribution network. The substation handles multiple voltage levels, including 345 kV and 69 kV, indicating its function as a step-down point between high-voltage transmission lines and lower-voltage distribution circuits. Operating under the regulatory oversight of the Federal Energy Regulatory Commission (FERC) and the North American Electric Reliability Corporation (NERC), the substation must comply with mandatory reliability standards. AEP Ohio, a subsidiary of American Electric Power, operates a large portfolio of generation, transmission, and distribution assets across the state. The substation's dual-voltage configuration is typical for facilities that interconnect bulk power transmission with local distribution networks. The substation's location in Ohio places it within the PJM Interconnection, one of the largest regional transmission organizations in the United States. As part of this grid, South Berwick Substation contributes to the reliable delivery of electricity to residential, commercial, and industrial customers. Its operational status ensures continued support for grid stability and power flow management in the region.
Environmental context
The substation is situated in a rural or suburban area of Ohio, where land use is a mix of agriculture and residential development. Electrical infrastructure like this typically has a localized environmental footprint, including electromagnetic fields and potential impacts on wildlife. The facility's design and operation are subject to environmental regulations that manage these effects, such as compliance with the National Environmental Policy Act (NEPA) for new projects. The surrounding landscape may include farmland and woodlands, which can influence vegetation management practices around the substation.
