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.
