Why Are We Doing This Project?
As part of our ongoing commitment to deliver reliable energy and superior service, we are replacing two existing 115-kilovolt (kV) underground transmission lines in the Hartford area.
These two existing transmission lines, installed in 1974, are past their expected operating life of 40 years and the material is no longer being widely produced by manufacturers.
Where Is This Work Being Done?
The 1704 underground transmission line runs from the Southwest Hartford Substation to South Meadow Substation, and the 1722 line runs from Southwest Hartford Substation to Northwest Hartford Substation.
