Opequon Substation - 138 kV Electrical Substation in the United States

Opequon Substation is an operational electrical substation located in the United States, with coordinates 39.438521, -77.956363. The facility operates at a voltage of 138 kV, placing it in the medium-to-high voltage range typical for sub-transmission and distribution substations. As part of the national grid, it contributes to the reliable delivery of electricity to surrounding areas. The substation operates under the regulatory framework of the United States, which includes NERC reliability standards for bulk power system stability and FERC oversight for interstate transmission. The 138 kV voltage level is commonly used for regional power distribution, connecting higher-voltage transmission lines to local distribution networks. Substations of this type often feature switchgear, transformers, and protection systems compliant with standards such as IEEE C37. Opequon Substation serves as a critical node in the local electrical infrastructure, supporting grid stability and power quality for residential, commercial, and industrial consumers. Its operational status ensures continued service to the community, and its location in the United States benefits from robust regulatory oversight and established maintenance practices.

The substation is located in a region with a temperate climate, where seasonal weather variations can impact grid operations. The 138 kV voltage level indicates a moderate scale of infrastructure, typically situated in suburban or rural areas to balance accessibility and environmental footprint. Substations of this type are designed with containment measures for insulating oils and other materials to minimize environmental risks.
