Earlville Substation - Operational Substation in the United States

Earlville Substation is an operational electrical substation located in the United States, owned and operated by Choptank Electric Cooperative. The facility serves as a key node in the regional power distribution network, stepping down transmission voltage for local distribution. The substation operates at voltage levels of 69 kV (transmission) and 12.47 kV (distribution), typical for a medium-voltage substation in rural cooperative systems. As part of the U.S. electrical infrastructure, it falls under NERC reliability standards and FERC regulation for grid stability and interconnection requirements. As a cooperative-owned asset, Earlville Substation supports the electric needs of member-consumers in the region. Its role in voltage transformation and grid reliability is essential for maintaining power quality and service continuity in the surrounding area.

The substation is located in a rural area of the Mid-Atlantic United States, where agricultural land and scattered residential developments dominate. Electrical infrastructure in such settings must balance reliability with minimal environmental footprint, often involving vegetation management and wildlife protection measures. The voltage levels indicate a role in both local distribution and sub-transmission, with potential impacts on nearby habitats through electromagnetic fields and land use.
