Transmission line construction continues in Charles County

Transmission line construction continues in Charles County

SMECO is committed to electric service reliability in Southern Maryland. As part of this commitment, the cooperative replaced an aging single-circuit 69,000-volt (69-kV) line with a double-circuit line on new steel poles from the Hawkins Gate switching station near La Plata to the Westlake substation near the St. Charles Towne Center. Construction took place between October 2013 and December 2014, and SMECO energized the new line on December 10, 2014. The double-circuit transmission line added capacity and improved reliability.

Because of the increased growth in Waldorf, the Westlake substation is one of the most heavily loaded substations in SMECO's service territory. The upgraded transmission line from Hawkins Gate switching station to the Westlake substation is the first of multiple projects planned for upgrading infrastructure in Charles County.

SMECO is now beginning another project that includes a new transmission line that will go from Hawkins Gate to the new Wooded Glen substation (just north of La Plata and Laurel Springs Regional Park) and to the new Dorchester substation. Construction of the two new substations will start in 2015, and they are scheduled to be energized in 2016.

In preparation for the installation of the new line, SMECO began clearing the right-of-way along Route 488 in October 2014 moving towards Dorchester. Penn Line is finishing the last section next to the CSX tracks now. The clearing is scheduled to be completed by March 1, 2015, and construction is expected to begin this summer.

The new lines and new substations will ensure continued reliability for that area of Charles County.
