L164/Y151 ACR

Project

About the Project

The L164/Y151 ACR project ensures the equipment can continue to deliver reliable power to customers. Most parts of the L164 and Y151 lines were upgraded in 2004, 2012, and 2014, except for the South Broadway Tap section. To check the condition of the South Broadway Tap section, crews conducted aerial inspections to look for issues that could affect reliability. This project will upgrade the L164/Y151 line between Tewksbury Junction and the South Broadway Tap to fix the issues found during the inspection. The project will also connect the West Andover and South Broadway substations to National Grid’s private fiber network. This will improve communication, reduce delays, and reduce the need for outside communication providers. Installing optical ground wire (OPWG) on this section will support safe and reliable communication between the stations and reduce costs from leasing communication services.
