Hanville Substation - 69 kV Electrical Substation in Ohio, United States

Hanville Substation is an operational electrical substation located in Ohio, United States. Owned and operated by FirstEnergy, a major utility in the region, the facility plays a critical role in the local power distribution network. The substation operates at a voltage level of 69 kV, which is typical for sub-transmission and distribution substations that step down power from higher voltage transmission lines to serve industrial, commercial, and residential customers. As part of the United States electrical infrastructure, Hanville Substation operates under the regulatory framework established by the Federal Energy Regulatory Commission (FERC) for wholesale electricity markets and the North American Electric Reliability Corporation (NERC) for reliability standards. The facility adheres to NERC's Critical Infrastructure Protection (CIP) standards, ensuring cybersecurity and physical security of bulk electric system assets. The 69 kV voltage class places it within the distribution-level infrastructure, which is essential for delivering electricity to end-users in the surrounding area. The substation's location in rural Ohio supports the regional grid's stability and reliability. FirstEnergy's ownership indicates integration into a larger utility network serving multiple states. The facility's operational status ensures continued service to the local community, contributing to the area's economic activity and quality of life. Its role in the electrical infrastructure underscores the importance of substations in maintaining a resilient power supply.

The substation is situated in a rural area of Ohio, where the surrounding landscape includes agricultural land and small communities. The 69 kV voltage level indicates a distribution substation, which typically has a smaller environmental footprint compared to high-voltage transmission substations. The facility's operation involves standard electrical equipment such as transformers and switchgear, which are designed to minimize electromagnetic field emissions and comply with local environmental regulations. The rural setting reduces potential impacts on densely populated areas, though the substation still requires vegetation management and stormwater controls to prevent runoff into nearby waterways.
