Second Street Substation - Ohio Electrical Substation Operated by AEP Ohio

Second Street Substation is an operational electrical substation located in Ohio, United States. Owned and operated by AEP Ohio, a major utility in the region, this facility plays a critical role in the local electrical infrastructure by stepping down transmission voltages for distribution. The substation operates at a voltage of 69 kV, which is typical for sub-transmission or distribution-level infrastructure in the United States. As part of AEP Ohio's network, it is subject to reliability standards set by the North American Electric Reliability Corporation (NERC) and regulated by the Federal Energy Regulatory Commission (FERC) for interstate transmission aspects. The facility's equipment likely includes circuit breakers, transformers, and switchgear compliant with IEEE and ISO/IEC 61850 standards for automation. Located in a region with a mix of industrial, commercial, and residential loads, Second Street Substation supports grid stability and power delivery to local communities. Its operational status ensures continued service, and its integration into AEP Ohio's broader system underscores its importance in maintaining reliable electricity supply in the area.

The substation's location in Ohio places it within a temperate climate zone, where seasonal weather variations can impact grid operations. The facility's 69 kV voltage level indicates it serves as a distribution node, likely in a suburban or rural setting. Its proximity to load centers minimizes transmission losses, and its design includes standard environmental safeguards such as oil containment for transformers to prevent soil and water contamination.
