About the Project
The Southern Reinforcement Project added overhead and underground transmission circuits in South Jersey. The project added two new 230kV overhead transmission circuits and three new 230kV underground circuits. 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 project installed approximately 12 miles of overhead transmission. A 10 mile overhead transmission circuit was added from PSE&G’s Gloucester Switching Station in Gloucester City to Atlantic City Electric’s Mickleton Substation in Mantua Creek. Also, a 2 mile overhead transmission circuit was installed in Pennsauken from PSE&G’s Camden Switching Station to PECO’s Richmond Substation.
This project added approximately 16 miles of underground transmission. A 7.5 mile underground transmission circuit was installed from the Gloucester Switching Station in Gloucester City to the Camden Switching Station in Pennsauken. A 5.5 mile underground transmission circuit was added from the Gloucester Switching Station in Gloucester City to the Cuthbert Boulevard Substation in Cherry Hill. Lastly, a 3 mile underground circuit was installed from the Cuthbert Boulevard Substation in Cherry Hill to the Camden Switching Station in Pennsauken.
PSE&G secured all necessary permits and approvals from municipalities along the route as well as the New Jersey Department of Environmental Protection and other appropriate state agencies.
Employment and Economic Benefits Report
The Brattle Group recently released a report on the employment and economic benefits of investing in transmission infrastructure, such as the Southern Reinforcement Project.
A robust transmission grid not only ensures reliable delivery of electricity but provides many other benefits such as reducing power production costs, facilitating renewable energy development, and providing insurance against extreme events such as local power shortages due to weather and other factors. Investment in transmission infrastructure also supports employment and stimulates the economy.
Economic benefits are significant. Each million dollars of transmission investment supports five to eight years of local full-time employment, with an expected economic impact of $1.4 million to $1.8 million.
According to the report, transmission infrastructure projects may be driven by a single concern, such as reliability, but may also relieve transmission congestion and enable future integration of lower-cost renewable resources. PJM Interconnection, the regional entity responsible for planning the transmission system, has noted that voltage upgrades can lower congestion costs by $1.7 billion, which benefits New Jersey ratepayers.
