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.

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

Q4 2021

We have completed surveying of the right-of-way, along with verifying subsurface conditions and underground utilities, and the installation of 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.  Road closures will be needed for this process.

On or about Friday, November 19, 2021, PSE&G and its contractors will utilize helicopter crews to help install the RPV transmission lines in parts of Chatham Township and the Township of Long Hill. The schedule for this activity is an estimated timeframe and may be slightly adjusted.

The helicopter activity is expected to last for two days, from 9 a.m. to 5 p.m., depending on the weather. This activity entails pulling ropes from one transmission structure to the next, using a small helicopter. 

On Friday, November 19, brief and intermittent road closures are anticipated along Long Hill Lane (Chatham Twp), Crestwood Rd., Meyersville Rd., Hickory Tavern Rd., Long Hill Rd. and Mountain Ave.  On Saturday, November 20, brief and intermittent road closures are anticipated along Crestwood Rd.

Meyersville Rd., Hickory Tavern Rd., Long Hill Rd., Mountain Ave., and Morristown Rd.

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.
