Overview
Dolehard Substation is an operational electrical substation in Ohio, United States, owned and operated by AEP Ohio. It operates at 69 kV, serving as a key node in the regional transmission grid.
Dolehard Substation is an operational electrical substation located in Ohio, United States. Owned and operated by AEP Ohio, the facility is part of the regional transmission network, stepping down voltage for distribution to local communities. The substation operates at 69 kV, a common sub-transmission voltage level that connects bulk power systems to distribution feeders. As a substation within the PJM Interconnection, Dolehard Substation adheres to NERC reliability standards and FERC regulations governing grid stability and security. The 69 kV voltage level indicates a medium-voltage facility typically serving urban or suburban areas, with switchgear and transformers designed for efficient power flow management. AEP Ohio, a subsidiary of American Electric Power, maintains a large portfolio of substations across the state. The substation plays a critical role in ensuring reliable electricity supply to surrounding areas, supporting residential, commercial, and industrial customers. Its operational status and integration into the broader PJM grid contribute to regional energy resilience and load balancing.
Environmental context
The substation is located in rural Ohio, an area with mixed agricultural and residential land use. The 69 kV voltage level suggests moderate electromagnetic field exposure, though standard setbacks and shielding are typically employed. The facility's operation involves minimal direct environmental impact, with oil-filled transformers managed under EPA spill prevention regulations. Its grid role supports local electrification without significant ecological disruption.
