The North Quincy Cable Project is the proposed replacement of the 115kV underground electric transmission cables (also known as the 532N and 533N cables) located between National Grid’s North Quincy Substation and National Grid’s Field Street Substation.
In recent years, National Grid has made numerous repairs to this cable system to enable continued delivery of electricity to our customers. Originally installed in 1973, these cables are nearing the end of their service life and need to be replaced.
National Grid is proposing to replace the existing cables with new, modern cables installed within a concrete duct bank, and manhole system. Replacement of these aging cables will improve electric reliability for our area customers, and minimize maintenance and repair costs, providing the capacity to meet growing electric energy needs.
National Grid is committed to actively working with local officials, residents, local businesses in Quincy, the Department of Conservation and Recreation, and the Department of Transportation to solicit feedback and maintain an open dialogue throughout the permitting and route selection process. Permitting began in the spring of 2020. Under our proposed schedule, we expect construction to begin in the summer of 2022 and to have the new cables in service by late 2023.
