The Roseland – Pleasant Valley Project (RPV) is a $546 million investment designed to strengthen the electric transmission system by replacing older transmission facilities between PSE&G’s Roseland Switching Station in Roseland, N.J., and its Pleasant Valley Switching Station in Hopewell, N.J. On average, these transmission facilities are approximately 90 years old.

Authorized in April 2018 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 51-mile project replaces existing lattice towers that have reached their end of life. The existing towers, most of which were built around the 1920s and 1930s from Roseland to Lambertville and in the 1960s from West Amwell to Pleasant Valley, will be replaced with new steel structures. The voltage of these transmission lines is remaining the same.

The project replaces aging infrastructure in 17 municipalities, spanning Essex, Morris, Somerset, Hunterdon, and Mercer counties, including Roseland Borough, Livingston Township, Florham Park Borough, Chatham Borough, Chatham Township, Long Hill Township, Bernards Township, Warren Township, Bridgewater Township, Branchburg Township, Hillsborough Township, Readington Township, Raritan Township, East Amwell Township, West Amwell Township, Lambertville City, and Hopewell Township.

In addition, this project makes minor modifications to three PSE&G electric stations, including Roseland Switching Station, Branchburg Switching Station and Pleasant Valley Switching Station.

The project is separated into two segments and requires overhead transmission modifications within existing PSE&G rights-of-way. Segment I of the project runs from Roseland to Branchburg, while Segment II runs from Branchburg to Pleasant Valley.  This project is anticipated to be in service in June 2023.


The segment of the Project spanning the Township of  Bridgewater entails the replacement of twenty-eight (28) existing lattice towers with twenty-six (26) Y-frame monopoles and two (2) H-frame structures, all of which  will remain within the existing ROW, with no additional  land rights required. The heights of the existing lattice towers that encompass the Project in Bridgewater range from approximately 72 feet to 131 feet and the  proposed heights of the new structures will range from  approximately 113 feet to 168 feet.

Bridgewater has two separate construction schedules.

The first planned segment started at the Readington Substation on Milltown Rd and heads north.

Q4 2022

We have completed surveying of the right-of-way, along with verifying subsurface conditions and underground utilities.  On or about the middle October 2022, you may see our crews on the right-of-way south of Readington Station installing temporary access roads. These temporary access roads, either stone or timber matting, allow for our construction traffic and work locations around each transmission structure. All construction activity will take place within the limits of the ROW.

Once completed, contractors will begin installation of the foundations for the new “Y” monopoles.  These new “Y” monopoles may shift along the centerline of the existing lattice towers, but will remain within the ROW.  This work may generate some unavoidable noise and vibration.  In addition, our contractors will begin the process of removing the wires from the existing structure.

Pursuant to the Bridgewater construction office, work hours will be Monday – Friday, 7:30 a.m. - 6 p.m. and Saturday, 8 a.m. - 4 p.m. All construction activity will take place within the limits of the ROW. 

Safety is our highest priority at PSE&G, and it is essential that you and anyone occupying your property refrain from going on the right-of-way during these activities.

August 14-18 2017

PSE&G will be completing underground construction activity on Main Street between Tea Street (Bound Brook) and STS Drive. Minor traffic changes may be required, including lane shifts. 

Safety is our highest priority. PSE&G is working with the Bridgewater 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.

69kV Initiative

Reliability Project Overview

PSE&G is currently conducting statewide electric reliability improvements to its utility infrastructure. These enhancements will improve both electric service reliability and system redundancy to ensure safe and reliable service to our customers. Throughout the state of New Jersey, PSE&G infrastructure upgrades will reduce the demand on the existing 26kV network. The projects will install 69kV transmission circuits connecting PSE&G stations around the state.
