Negley Substation: AEP Ohio 138 kV Electrical Substation in Ohio

Negley Substation is an operational electrical substation located in Ohio, United States. Owned and operated by AEP Ohio, the facility plays a critical role in the regional power transmission network, stepping down high-voltage electricity for distribution to local communities and industries. The substation operates at a voltage of 138 kV, which is a standard transmission-level voltage in the United States. As part of AEP Ohio's infrastructure, it is subject to reliability standards set by the North American Electric Reliability Corporation (NERC) and regulated by the Federal Energy Regulatory Commission (FERC). The facility's equipment likely includes circuit breakers, transformers, and switchgear compliant with IEEE standards. Negley Substation contributes to grid stability in the region, supporting the integration of diverse generation sources and ensuring reliable power supply to residential, commercial, and industrial customers. Its location in Ohio places it within the PJM Interconnection, one of the largest regional transmission organizations in the U.S., which coordinates electricity movement across multiple states.

The substation's location in Ohio places it within a temperate climate zone, where seasonal weather variations can impact grid operations. The facility's 138 kV voltage level indicates it is a transmission substation, likely situated in a rural or suburban area to balance land use and proximity to load centers. Its operation involves minimal direct environmental impact, though electromagnetic fields and potential oil leaks from transformers are managed through standard industry practices.
