The Burlington Camden Reliability Project will upgrade existing overhead and underground transmission circuits from 138kV to 230kV operation in South Jersey. The upgrade will deliver increased electric capacity required by New Jersey business and residents, increase transfer capability, provide better power quality, and reduce transmission system congestion.
This overall project is approximately 37-circuit miles and is divided into overhead and underground portions. This project will upgrade approximately 30-circuit miles from PSE&G’s Burlington Switching Station located in Burlington City and Burlington Township, New Jersey to PSE&G’s Camden Switching Station located in Pennsauken, New Jersey. Also, an existing 7-circuit miles of 138kV underground circuit will be replaced and upgraded for 230kV operation from PSE&G’s Camden Switching Station in Pennsauken, New Jersey to PSE&G’s Gloucester Switching Station in Gloucester City, New Jersey.
PJM Interconnection LLC, the regional entity responsible for transmission system planning, identified the need for this important project and assigned it to PSE&G to enhance reliability of electricity supplies in the region.
New Jersey Regional Benefits
Customers are using more electricity to power everything from big screen televisions to the latest kitchen appliances. As the continued demand for safe, highly reliable electricity grows due to increased population growth in both Burlington and Camden counties, additional transmission lines are needed to meet this need now and into the future.
The PSE&G Burlington Camden Reliability Project is designed to deliver the electric power required by southern New Jersey businesses and residents. Analysis has shown that voltage violations near the Burlington and Camden 138 kV stations would result in unplanned outages. The recommended solution to address these voltage violations is to upgrade and convert the existing transmission lines, substations and switching stations from 138 kV to 230 kV. This project will relieve transmission system overloads, provide better power quality, and reduce transmission system congestion experienced in the region.
Project at a Glance
Estimated Project Cost: $399 million
Voltage Upgrades: 230 kV
Underground Transmission Upgrades
- Underground work will replace 138 kV cables with 230 kV cables from the Camden Switching Station (Pennsauken) to Cuthbert Boulevard Substation (Cherry Hill) and onto the Gloucester Switching Station (Gloucester City).
- The cables will be installed in existing underground pipes from Camden Switching Station (Pennsauken) to Cuthbert Boulevard Substation (Cherry Hill) to Gloucester Switching Station (Gloucester City) and will be upgraded for 230 kV operation. The distance of the underground portion is approximately 7 miles.
Overhead Transmission Upgrades
- The overhead project will go through Burlington City, Burlington Township, Willingboro, Delran, Cinnaminson and Pennsauken along an existing PSE&G overhead right-of-way.
- The existing six 138 kV wires will be reconfigured to three and will be operated at 230 kV on the existing towers.
- The distance of the overhead portion is approximately 15 miles.
- The following stations will be upgraded to 230 kV operation: Burlington Switching Station (Burlington City and Township), Levittown Substation (Willingboro), Cinnaminson Substation (Cinnaminson), Camden Switching Station (Pennsauken), Cuthbert Blvd. Substation (Cherry Hill) and Gloucester Switching station (Gloucester City).
- The routes selected follow existing PSE&G rights-of-way for both the overhead and underground portions of the project.
Anticipated Project Schedule
Underground Construction Start Date: March 2011
Overhead Construction Start Date: 1st Quarter 2012
Substation and Switching Station Construction: 2nd Quarter 2012
Estimated In-Service Date: June 2014
The project will secure the necessary permits and approvals from municipalities along the route as well as the New Jersey Department of Environmental Protection and other appropriate state, regional and federal agencies.
