Darrow/Terex Substation - Ohio Electrical Substation | United States

Darrow/Terex Substation is an operational electrical substation located in Ohio, United States. Owned by Ohio Edison, a subsidiary of FirstEnergy, this facility plays a key role in the regional power grid. The substation handles multiple voltage levels, including 138 kV, 69 kV, and 12.47 kV, indicating its function in both transmission and distribution. As part of the United States electrical infrastructure, this substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). Ohio Edison, as a utility, adheres to NERC reliability standards to ensure grid stability. The substation's voltage levels suggest it serves as a critical node for stepping down power from high-voltage transmission lines to lower voltages for local distribution. The substation's location in Ohio places it within the PJM Interconnection, one of the largest regional transmission organizations in the US. Its operational status and voltage capacity indicate its importance in maintaining reliable electricity supply to residential, commercial, and industrial customers in the area. The facility contributes to grid resilience and supports the integration of diverse power sources.

The substation is situated in a region with a mix of urban and suburban development, typical of northeastern Ohio. The local electrical infrastructure must accommodate seasonal weather variations, including winter storms and summer heat waves, which can impact grid reliability. The substation's voltage levels and location suggest it supports both residential and industrial loads, with potential environmental considerations related to electromagnetic fields and land use. Proper maintenance and adherence to environmental regulations help mitigate any local ecological impacts.
