Mt. Pleasant to Glasgow

The Mt. Pleasant to Glasgow project is a 138 kV line that runs along the existing transmission corridor that goes west from the Mt. Pleasant Substation, north along the Maryland/Delaware state lines, across the C & D Canal, and then to the Glasgow Substation. The project work involved replacing the current, double-wood-pole “H” frame style line with two single-steel-pole lines. One set of the new steel poles will replace the existing transmission line and the other set of new steel poles will be used for a new transmission line. Both lines are the same voltage – 138 kV – as the existing “H” frame line. Construction work began in March of 2012 and was completed in 2013.
