An overhead transmission line is a set of three wires, called conductors, attached to structures that deliver electric power from generating sources (aka wind turbine, solar, etc) to customers. The power is then distributed to consumers from the substations through lower-voltage distribution lines. The three transmission line conductors carry the electric power, but transmission lines also may have one or two smaller wires called shield wires at the top of the structure that protect the line from lightning strikes. Transmission lines are designed to operate at a specific design voltage. The higher the voltage, the more electric power a transmission line can carry.
PSE&G’s Southern Reinforcement Project will ensure reliable electric power for the southern New Jersey region by providing additional 230,000 volt (230kV) lines to the area.
People are using more electricity to power everything from big-screen televisions to computers and the latest kitchen gadgets. The existing southern New Jersey infrastructure, some of which dates back to the 1940s, was built before the popularity of computers, large televisions, iPods, cellular phones and other electric devices that have become common in our lives. Population trends indicate continued growth in the region.
The PSE&G Southern Reinforcement Project is designed to deliver the electric power required by southern New Jersey businesses and residents. The project will relieve transmission system overloads, provide better power quality, and reduce transmission system congestion experienced in the region.
The selected routes follow existing PSE&G rights of way for the overhead potion of the project and is has been primarily sited in road rights of way for the underground route to avoid impact on private property.
Underground transmission wire upgrades will take place in Pennsauken, Merchantville, Cherry Hill, Collingswood, Woodlynne, Camden, Haddon Township, Audubon, Mt. Ephraim and Gloucester City. Additional overhead lines will be installed in existing rights of way in Pennsauken, Gloucester City, Brooklawn, Westville, Woodbury City, Deptford and West Deptford. Also, upgrades will occur at several PSE&G switching stations. They are: Gloucester Switching Station (Gloucester City) Deptford Substation (Deptford) and Thorofare Substation (West Deptford).
Overhead and Underground construction may begin in the second quarter of 2013. Switching Station upgrades began in Gloucester City in December 2012.
The project cost is estimated to be $435 million.
The upgrade will help the region’s utilities meet the growing demand for safe, reliable electricity.
The Southern Reinforcement Project will secure necessary approvals and permits from government entities along the route, including municipalities, the New Jersey Department of Environmental Protection, the Army Corps of Engineers and Camden and Gloucester counties.
Why doesn’t PSE&G focus on energy conservation and alternative energy sources like solar and wind power?
PSE&G is committed to initiatives already under way to reduce electric use by boosting energy efficiency and renewable energy sources. But even with these alternatives, statewide electric demand is still expected to increase. This upgrade is needed to meet regional demand.
Electric and magnetic fields are present wherever there is a flow of electric current, whether in wires in the home, electrical appliances, or power lines. Electric fields are produced by the voltage or electrical pressure in a wire and are present even if an appliance is turned off, as long as it is connected to a source of electric power. Magnetic fields are produced whenever there is a flow of electric current through a wire. Electric and magnetic fields are not visible, like other fields such as a gravitational field or a temperature field.
The overwhelming body of scientific study shows no definitive link between EMF and human health issues. Since 1977, concerns over magnetic fields and possible health effects have been the subject of numerous scientific and regulatory review panels, and extensive research and studies continue to be funded in this field of study.
After nearly 30 years of worldwide research, there are no direct or causal links between electric and magnetic fields and adverse health effects. New Jersey has standards regarding maximum permissible electric fields at the edge of transmission line rights of way. However, there are no state standards with regards to magnetic field levels nor are there any federal rules, regulations or standards for either electric or magnetic field levels.
Magnetic fields from appliances like hair dryers, microwave ovens, and motorized appliances are often stronger than the fields directly beneath power lines. PSE&G will design and install this line according to appropriate state and federal guidelines related to safety and environmental impact.
