Building for Reliability

SMECO continuously works on projects to improve the reliability of our electric system.

Lexington Park Substation Upgrades:

SMECO is rebuilding the Lexington Park substation to expand its load capacity. The Co-op has replaced the substation’s two large transformers. One of them will eventually move to the Milestown substation, which is also slated for a rebuild.

One side of the Lexington Park facility has a new 69-kV circuit breaker, new switches, and new reclosers. In October 2022 SMECO will begin replacing the infrastructure on the other side of the substation. The upgrade at Lexington Park includes a new control house, powered by two new service transformers.

New Substation & Transmission Line in St. Mary’s County:

SMECO has built a new substation in Chaptico. The facility will add capacity to our transmission system in the northern part of St. Mary’s County, absorbing some of the load from four other substations in the area. To supply electricity to the Chaptico substation, SMECO plans to build seven miles of 69-kV transmission line from the Ryceville substation. The new line will use SMECO’s existing right-of-way for the 230-kV line that connects the Ryceville and Hewitt Road switching stations. Construction on the new 69-kV line began in March 2022 and will be complete in October, so that Chaptico can be energized in the fourth quarter of 2022.

Path for the new 69-kV transmission line, which will use the existing right-of-way in the area.
