About the Project
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.
Authorized in February 2017 by PJM Interconnection (PJM), the regional transmission organization responsible for planning the transmission system in all or parts of 13 states, including New Jersey, the 55-mile reliability project replaces critical infrastructure that has reached its end of life and improves capacity significantly, while addressing voltage violations in the Metuchen area. On average, these transmission facilities are 80-plus years old.
The project replaces aging infrastructure in 17 municipalities, spanning Burlington, Mercer and Middlesex counties, including Edison, Milltown, East Brunswick, New Brunswick, North Brunswick, South Brunswick, Plainsboro, West Windsor, Hamilton, Chesterfield, Bordentown, Mansfield, Florence, Springfield, Burlington, Willingboro, and Burlington City.
Additionally, the project modifies, upgrades or reconfigures 17 electric stations, including Metuchen Switching Station, Pierson Avenue Substation, Meadow Road Substation, Edison Switching Station, Brunswick Switching Station, Devils Brook Substation, Plainsboro Substation, Dey Road Switch Rack, Forrestal Substation, Trenton Switching Station, Yardsville Substation, Ward Ave Substation, Colonial Pipe, Crosswicks Area Substation, Williams Substation, Bustleton Substation, and Burlington Substation.
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.
