Sylvania Substation: 138 kV Electrical Substation in Ohio, United States

Sylvania Substation is an operational electrical substation located in Ohio, United States. Owned and operated by FirstEnergy, the facility plays a key role in the regional transmission network, stepping down high-voltage electricity for distribution to local communities. The substation operates at 138 kV, a common voltage level for subtransmission systems that connect bulk power sources to distribution networks. Operating under the regulatory oversight of the Federal Energy Regulatory Commission (FERC) and the North American Electric Reliability Corporation (NERC), the substation adheres to mandatory reliability standards. These standards ensure grid stability, cybersecurity, and maintenance protocols. As part of FirstEnergy's infrastructure, the facility benefits from the company's extensive experience in managing transmission assets across the Midwest and Mid-Atlantic regions. The substation's location in Ohio places it within a region with a diverse industrial and residential load profile. Its role in voltage regulation and power flow management supports grid reliability for surrounding communities. The facility's operational status and integration into FirstEnergy's network underscore its importance in maintaining consistent electricity supply.

The substation is situated in an urban-suburban area of Ohio, where land use includes residential, commercial, and industrial zones. Its operation involves electromagnetic fields and potential noise from transformers, which are managed through standard mitigation practices. The facility's design and maintenance follow environmental guidelines to minimize impact on local ecosystems and communities.
