Miles Avenue Substation - 138 kV Electrical Substation in Ohio, United States

Miles Avenue Substation is an operational electrical substation located in Ohio, United States. Owned and operated by AEP Ohio, the facility is part of the state's high-voltage transmission network, stepping down power for distribution to local communities. With a voltage level of 138 kV, it is classified as a medium-to-high voltage substation, typical for regional grid interconnection and industrial supply. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for bulk power systems. AEP Ohio, a subsidiary of American Electric Power, manages the facility in compliance with these standards, ensuring grid stability and safety. The 138 kV voltage level is common for sub-transmission systems, linking larger transmission lines to distribution networks. Environmentally, the substation's location in Ohio places it within a region with diverse energy mix, including coal, natural gas, and renewables. Its role in the grid supports reliable electricity supply to residential, commercial, and industrial users. The facility's operational status contributes to the resilience of the local power infrastructure, particularly during peak demand periods.

The substation is situated in an urbanized area of Ohio, where electrical infrastructure plays a critical role in supporting local communities and industries. The 138 kV voltage level indicates its function in sub-transmission, balancing grid stability and load distribution. The facility's age and equipment condition are typical for substations of this scale, with regular maintenance ensuring minimal environmental impact from potential oil leaks or SF6 emissions.
