MASSACHUSETTS – National Grid plans to begin the second phase of construction for the $92 million North Quincy Cable Replacement Project, an 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 new cables will be installed within a concrete duct bank and manhole system.
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 2,100-foot section of the new conduit system on Newport Avenue to the West Squantum Street overpass.
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 should help improve safety and reliability and provide the area’s transmission grid with greater operational flexibility, National Grid said in a press release.
“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 of 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.”
The next phase construction works are expected to start in April and continue until near the end of 2023.
