Leonardtown Substation is an operational electrical substation located in Leonardtown, Maryland, United States. Owned and operated by Southern Maryland Electric Cooperative (SMECO), it plays a key role in distributing electricity to the surrounding community. The substation operates at voltage levels of 69 kV and 12.47 kV, indicating its function as a distribution substation stepping down transmission-level power for local use. As part of the U.S. electrical infrastructure, this facility operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) reliability standards and the Federal Energy Regulatory Commission (FERC) for interstate transmission. SMECO, a member-owned cooperative, adheres to these standards to ensure grid stability and reliability. The substation's dual voltage levels suggest it connects the transmission grid to distribution networks, typical for rural and suburban cooperatives. The substation's location in southern Maryland places it in a region with a mix of residential, agricultural, and commercial loads. Its operational status ensures continued service to the community, supporting local economic activities and daily life. The facility's integration into SMECO's network highlights its importance in maintaining reliable electricity supply in the area.

The substation is situated in a rural-suburban area of southern Maryland, characterized by mixed land use including residential developments and farmland. The local environment is influenced by the Chesapeake Bay watershed, with considerations for stormwater management and habitat preservation. As an electrical infrastructure facility, its environmental impact is primarily related to electromagnetic fields and land use, though modern substations are designed to minimize ecological disruption.
