The SMECO service territory includes Charles County, St. Mary's County, the southern portion of Prince George's County, and most of Calvert County, Maryland. The Cooperative's Distribution Network is supplied from six separately metered intertie points within the PEPCO Transmission Zone of the PJM Control Area.
