Owned by Southern Maryland Electric Cooperative, it plays a key role in distributing electricity to the surrounding area. The substation is part of the regional transmission and distribution network, supporting reliable power delivery to residential and commercial customers. The substation operates at voltage levels of 69 kV and 12.47 kV, typical for sub-transmission and distribution substations in the United States. As a facility under the jurisdiction of the North American Electric Reliability Corporation (NERC), it adheres to reliability standards that ensure grid stability and security. The cooperative ownership model reflects a common structure in rural electric systems, where member-owned utilities prioritize local service. Hughesville Substation contributes to the electrical infrastructure of southern Maryland, an area with a mix of rural and suburban development. Its operational status ensures continued support for community energy needs, including residential, agricultural, and small industrial loads. The substation's role in voltage transformation and distribution is critical for maintaining power quality and reliability in the region.

The substation is situated in a rural-to-suburban transition zone in southern Maryland, where land use includes agriculture, forests, and low-density residential development. Electrical infrastructure in such areas typically requires careful siting to minimize visual and ecological impact, including consideration of wildlife corridors and stormwater management. The facility's operation involves standard electromagnetic field management and oil containment for transformers, aligning with environmental best practices for substations.
