West Milersburg Substation - 138 kV Electrical Substation in Ohio, United States

West Milersburg Substation is an operational electrical substation located in Ohio, United States. Owned and operated by Holmes-Wayne Electric Cooperative, it serves as a key node in the local distribution network, stepping down transmission-level voltage for rural and suburban consumers. The substation operates at 138 kV, a common voltage level for sub-transmission and distribution in the United States. As part of the cooperative's infrastructure, it adheres to NERC reliability standards and FERC regulations for grid stability. The facility's equipment likely includes circuit breakers, transformers, and switchgear compliant with IEEE standards. This substation plays a vital role in delivering electricity to Holmes-Wayne Electric Cooperative's members, ensuring reliable power supply for residential, agricultural, and small commercial loads. Its location in rural Ohio supports the region's energy needs while maintaining grid resilience through compliance with North American electric reliability standards.

The substation is situated in a rural area of Ohio, where agricultural land and small communities dominate the landscape. Electrical infrastructure in such settings typically has minimal direct environmental impact, though proper maintenance of insulating fluids and vegetation management around rights-of-way are standard practices to prevent soil and water contamination. The 138 kV voltage level indicates moderate electromagnetic field exposure, which is managed through siting and shielding regulations.
