Reliability Project Overview

The Metuchen-Trenton-Burlington Project (MTB) is a $739M investment designed to strengthen the electric transmission system by replacing 138,000-volt (138kV) circuits with 230,000-volt (230kV) circuits between the PSE&G Metuchen Switching Station in Edison, NJ and the PSE&G Burlington Switching Station in Burlington, NJ.  The project replaces aging infrastructure in 17 municipalities and modifies, upgrades or reconfigures 17 electric stations.

The project is separated into three segments and requires overhead transmission modifications within existing PSE&G right of ways. The existing 138kV lattice towers supporting the overhead lines will be replaced with monopoles.  Segment IA of the project runs from Metuchen to Brunswick, while Segment IB runs from Brunswick to Trenton. Segment II runs from Trenton to Burlington. This project is anticipated to be in-service in June 2022.

NOTE: Construction schedule information is tentative and subject to change based on several factors, including weather and field conditions.

Q1 2019 - Q1 2020

On or about Saturday, March 28, 2020, PSE&G and its contractors will utilize helicopter crews to help install the MTB transmission line from the transmission structure near University Drive to the transmission structure on the southbound side of Interstate 295. The schedule for this activity is an estimated timeframe and may be slightly adjusted.

This helicopter activity in Hamilton is expected for a four-day period, from 8 a.m. to 6 p.m., weather permitting. This activity entails pulling a rope from one transmission structure to the next using a small helicopter. Brief and intermittent road closures are expected along University Drive, Flock Road, Edinburg Road, Paxson Road, Mount Drive, Alton Road, McAdoo Avenue, Marshall Avenue, Wilson Avenue, Hoover Avenue, Nottingham Way, State Highway 33, Whitehorse Avenue, and I-295.

Safety is our highest priority. PSE&G will work with the Hamilton Police Department to minimize any traffic concerns or inconvenience to the public. It is essential that you and anyone using your property, including children and pets, refrain from going near our construction work zones. For construction activities in and on the public right of way, local authorities will provide traffic control to keep both our work crews and the traveling public safe.

We apologize for any inconvenience this may cause and thank you for your understanding as we improve electric service reliability for your neighborhood and the region.

69kV Initiative

June 2020

On or about Monday, June 15, 2020, construction to expand the substation along Clinton Avenue will begin.  This project will improve the performance of the electric transmission system and maintain safe, reliable electric service for residents and businesses in Hamilton and surrounding communities.  These upgrades include building a new, two-story structure to enclose equipment and controls. The structure is designed to blend with the existing neighborhood. 

Work hours will be between 7 a.m. and 5 p.m., Monday through Friday, as well as some nights and weekends, as needed. Construction will continue through the winter of 2022 with landscaping and final restoration completed by the spring of the following year.
