Eldean Substation is an operational electrical substation located in Ohio, United States. Owned and operated by Dayton Power & Light, it plays a key role in the regional electrical infrastructure. The substation operates at a voltage of 138 kV, which is typical for sub-transmission and distribution-level assets in the US grid. As part of the US electrical infrastructure, Eldean Substation operates under the regulatory framework established by the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These standards ensure grid reliability and security. The substation's voltage level places it in the medium-to-high voltage range, supporting local distribution networks and industrial customers. The substation's location in Ohio, a state with a diverse industrial base and significant electricity demand, underscores its importance in maintaining grid stability. Its operational status and connection to the broader transmission network contribute to the reliable delivery of electricity to homes and businesses in the region.

The substation is situated in a rural area near Troy, Ohio, surrounded by agricultural land and residential communities. Its operation involves standard electromagnetic fields and noise, which are managed through typical substation design practices. The site's location away from sensitive ecological areas reduces direct environmental impact, though its role in the grid supports regional energy distribution.
