Why Are We Doing This Project?
As part of our ongoing commitment to deliver reliable energy and superior service to our customers, we are proposing to replace existing 115-kilovolt (kV) high pressure fluid-filled (HPFF) underground transmission lines with new 115-kV cross-linked polyethylene (XLPE) transmission lines.
Two underground transmission lines in Danbury, the 1270 and 1337 lines, were built in 1976 and are past their useful life expectancy. Replacing the existing HPFF with XLPE will modernize the existing transmission system and increase reliability.
The proposed project is part of a larger program we are conducting throughout our service territory in Connecticut and Massachusetts related to underground cable modernization. This program is designed to modernize and increase the capacity of the existing underground transmission cable systems by replacing existing fluid-filled cable with cross-linked polyethylene cable.
Where Is This Work Being Done?
The 1270/1337 underground transmission lines run from Triangle Substation to Middle River Substation, both in Danbury, Connecticut.
