Dobbins Substation - Ohio Electrical Substation Operated by Ohio Edison

Dobbins Substation is an operational electrical substation located in Ohio, United States, and operated by Ohio Edison, a subsidiary of FirstEnergy. The facility operates at a voltage of 138 kV, classifying it as a sub-transmission or distribution-level substation that plays a role in stepping down power for local distribution. As part of the U.S. electrical infrastructure, Dobbins Substation operates under the regulatory framework established by the Federal Energy Regulatory Commission (FERC) and the North American Electric Reliability Corporation (NERC) reliability standards. The substation likely employs conventional air-insulated or gas-insulated switchgear, typical for facilities of this voltage class in the region. The substation contributes to grid stability and reliability in the surrounding area, supporting residential, commercial, and industrial loads. Its location in Ohio places it within the PJM Interconnection regional transmission organization, which coordinates the movement of wholesale electricity across multiple states.

The substation is situated in a region with a temperate climate, where seasonal temperature variations can affect electrical demand and infrastructure performance. The surrounding area is a mix of urban and rural land uses, with the substation's footprint designed to minimize local environmental impact through standard containment and safety measures for insulating fluids and equipment.
