National Grid to Begin Second Phase of North Quincy Cable Replacement Project

March 21, 2022
The next phase of the project will start with construction beginning on Newport Avenue near West Squantum Street and will proceed down Newport Avenue to Furnace Brook Parkway.

National Grid plans to begin its second phase of construction for the US$92 million North Quincy Cable Replacement Project, a major investment to modernize and strengthen the electric transmission network in Quincy.

The North Quincy Cable Project is slated to replace the 115-kV underground electric transmission cables located between National Grid’s North Quincy Substation and  the company’s Field Street Substation. The existing cables are nearly 50 years old, and in recent years National Grid has made numerous repairs to ensure continued reliable delivery of electricity to customers. The old cables will be replaced with new modern cables installed within a concrete duct bank and manhole system.

Work on the first phase of the project was completed last year, as National Grid used a horizontal directional drilling process and other conventional construction methods to install an approximately 2100-ft section of the new conduit system on Newport Avenue to the West Squantum Street overpass.

The next phase of the project will start with construction beginning on Newport Avenue near West Squantum Street and will proceed down Newport Avenue to Furnace Brook Parkway; turning east on Furnace Brook Parkway to the Southern Artery; then south on Southern Artery to Morrison Street; turning east on Morrison Street and terminating at National Grid’s substation. Construction is expected to start in April and expected to continue through until near the end of 2023.

National Grid has worked closely with and received extensive input from municipal officials, including the Quincy Department of Public Works, the city’s traffic engineer, the Water & Sewer division and other local stakeholders. The project will help improve safety and reliability and provide the area’s transmission grid with greater operational flexibility. It will also improve the system’s ability to support new customers in the region and continued service for residents and businesses.

National Grid is seeking permits to undertake work from the Quincy City Council on March 21. In addition, the company is holding a virtual open house on March 29 at 6:30 p.m.  Interested parties are encouraged to pre-register for the meeting here.

“We look forward to the next phase of this important project.  Installing this modernized cable will ensure reliability for Quincy and surrounding communities, and allow for economic growth in the region,” said Tim Moore, vice president, electric project management and construction, National Grid New England. “We will do everything we can to minimize traffic disruption throughout this project and appreciate everyone’s patience.”

Project benefits include:                                                   

  • A safer, more reliable and resilient electric transmission system to support our customers in Quincy and surrounding communities. 
  • Enhanced ability to meet growing electric energy needs.
  • Modern cables protected by concrete duct bank.
  • More efficient means of maintenance and repair.
  • Increased property tax revenues for Quincy.
